Our L-4 was based in the US During WWII from 1943 to 1945. We bought
it early this year and have enjoyed every minute of it. The stearman was built
in 1942 during WWII and we have owned it since 1975.
Owning and operating antique aircraft has been a part of our family for 3
generations going back to 1963 when my father Tom bought a Piper Tri-
pacer. Our family has owned aircraft ever since. Our aviation roots rundeep in this family, and that is why we choose AUA as our agency. They
have a long distinguished record of service with the types of aircraft we
operate, and understand our problems and concerns.

AirVenture 2012 is now amere five months down
the road! Wow, there is so
much going on right now,
and so much to accomplish before
July sneaks up on us yet again. Ev-
ery year I tell our Vintage volun-
teer group that the goal is to always
outdo ourselves from one year to the
next. The volunteer work weekendsare already completely planned out,
and we’re ready to launch into yet
another year of accomplishment on
the grounds at EAA. It’s going to be
another great year at Oshkosh, so I
hope you will be able to join us for
another exciting event full of avia-
tion and excitement.Planning for the Cubs2Osh-
kosh event is already gaining a fair
amount of steam. This will certainly
be an event to remember. With the
exception of the wonderful yearly
Sentimental Journey fly-in that
takes place in Lock Haven, Pennsyl-
vania, I don’t believe you could ever
see a bigger field of yellow Cubs; it
will be a magnificent thing to see.
I have been really impressed with
the number of folks who have al-
ready committed to participating in
the 75th anniversary of the beloved
ers who are also planning to makethe trip. Be sure to click on the
“Cubs Location” link and check out
the map that shows where all of the
Cubs will be coming from. A num-
ber of individuals are already plan-
ning to hook up with other Cub
pilots traveling from the same gen-
eral area en route to Oshkosh.
VAA Director/CFI Steve Krog, whoowns and operates several Cubs out
of the Hartford, Wisconsin, Munic-
ipal Airport (HXF), has graciously
reached out to the community of
Hartford and has already experi-
enced a large interest from them
desiring to participate as a host com-
munity/gathering spot for the manydozens of Piper Cubs en route to
AirVenture Oshkosh. Hartford, Wis-
consin, is conveniently located 33
miles northwest of Milwaukee and
is a convenient short 60-mile flight
to Oshkosh. Hartford has a grass
strip (2,250 feet), and self-serve fuel
is available. Several other airports
around the country are also plan-ning to host our Cub pilots while
en route to Oshkosh, and that infor-
mation will be kept updated on the
forums area of the Cubs2Oshkosh
website. The parking/camping ar-
House and Senate conferees havenow managed to work out their dif-
ferences and recently finalized the
language in the bill. The U.S. Sen-
ate overwhelmingly passed the FAA
Reauthorization Bill, 75-20, on Feb-
ruary 6, so it’s now headed to the
president’s desk for signature. If the
president signs the bill, the FAA will
have its first long-term funding plansince 2007. This will finally end the
string of 23 short-term funding ex-
tensions that have kept the FAA op-
erating since 2007, and will allow
the agency to plan and implement
some of its key projects and initia-
tives. EAA and other aviation groups
have long worked hard to have lan-guage included that benefits GA in
a variety of areas, including no user
fees or aviation fuel tax increases,
funding for airport improvement
projects and the NextGen air traffic
control system, as well as progress
for vintage aircraft data and airport
through-the-fence agreements. This
effort toward a full FAA reauthoriza-tion bill was the result of GA groups
being stronger together to repre-
sent our members and all aviators.
But, it’s not all good news for our
local airports that may now experi-

VAA NEWS
SOME VINTAGE AIRCRAFT OWNERS got a big win in theFAA reauthorization bill signed in early February by Presi-dent Obama, as the measure included an EAA-supported
provision that authorizes the FAA to release certain typecerticate and design data for aircraft no longer supportedby a manufacturer.
Te specic element of the bill (Section 302) providesthat the FAA can release “abandoned” data that is essen-tial to safely maintain and operate vintage aircraft. Tatincludes data for aircraft such as those built by long-defunct companies whose type certificates were not ac-quired or maintained. Tree years is the initial threshold
for inactivity. It also gives the FAA the authority to de-clare that data as abandoned, or releasable to the publicif aviation safety will be enhanced by the information foraircraft, engines, propellers, and other aircraft appliances.
“Tis is great progress for those who own and restorevintage aircraft and preserve our aviation legacy,” said
ing data relating to aircraft that were certifi-cated between 1927 and 1939, and precludesthe destruction of any such airworthiness
and historically significant documentation.Te amendment also eliminates the ability oftype certificate holders from that period toforce the FAA to withhold such data under theclaims of “trade secrets.” Te amendment wasproposed by longtime EAA member Greg Her-rick, an owner and restorer of numerous vin-tage aircraft, and included in the legislation byRep. Sam Graves (R-Missouri).
“There are two initial and complementaryvictories contained in the nearly decade-longeff ort: the preservation and release of histori-cally significant documentation necessary torestore and maintain truly antique prewar air-
craft contained in the Herrick Amendment, and the EAAinitiative giving the FAA authority to release the designand airworthiness data for both pre- and post-World War
II general aviation aircraft that are no longer supported bya manufacturer,” said Doug Macnair, EAA vice presidentof government relations.
“These efforts do not give completely unfettered ac-cess to design data,” continued Macnair, “ but they do goa long way toward helping owners of antique and vintageaircraft maintain these beautiful ying pieces of history.Te EAA eff ort also seeks to protect not only owners ofaircraft that are no longer supported by a manufacturer,
but also those that may not be supported in the future,making this a long-term protection for all general avia-tion owners. We are very grateful to the FAA for theircollaboration in this effort and their willingness to in-troduce the original language into the early drafts of thereauthorization bill on behalf of EAA and all who own

User Fees: Good News,Bad News
The possibility of GA user fees justwon’t go away, despite more than a
decade of congressional oppositionfrom both parties and overwhelmingnegative responses from the aviationcommunity. Already in early 2012 wehave heard good news and bad newson the subject.
First the good news: T he finallanguage in the first full FAA reau-
thorization bill in five years passedboth houses of Congress in earlyFebruary and was signed by Presi-dent Obama on Feb. 14. It containsno provision for user fees and no in-crease in the aviation fuel tax, whichis GA’s fair contr ibution to FAA’sfunding. The reauthorization billwas a goal of EAA’s advocacy efforts,
as it stabilizes the agency’s fundingand planning through 2015 and al-lows major initiatives such as Next-Gen and airport improvements tomove forward.
N o w f o r t h e b a d n e w s : T h eObama administration’s proposedFiscal Year 2013 budget includes a
$100-per-flight user fee for selectedGA aircraft fl ying within controlledairspace. While the budget proposalwould exempt all piston aircraft, mil-itary aircraft, public aircraft, air am-bulances, aircraft operating outsideof controlled airspace, and Canada-to-Canada flights, the plan wouldcreate additional financial burdens
for GA and require new bureaucracyto administer user fee collection. Italso opens the door to an eventualexpansion of user fees to other pri-vate aircraft and GA operations.

EAA Skiplane Fly-InLike so many locations here in the north-
ern half of the United States, the winter hasbeen unusually mild (yes, we consider 25
degrees F to be a mild winter!) and very dry,with little snowfall. Happily, there’s beenexactly one Saturday when the annual EAASkiplane Fly-In at Pioneer Airport couldhave accommodated skiplanes, and that wasSaturday, January 21. With just the rightamount of snow on the ground, 33 skiplanesflew in and participated, joining hundreds
of attendees on the ground. A last-minutesnowfall the day before covered Pioneer’srunway, drawing planes from three states.Te gathering was also a celebration of
Audrey Poberezny’s birthday, and attend-ees enjoyed celebratory chili, soup, andbirthday cake inside one of the Pioneer Air-port hangars.
EAA’s Sweepstakes Cub sporting new
TrickAir wheel-penetration skis was a pop-ular participant, prompting several attend-ees to enter the sweepstakes on the spot. Alist of attending skiplanes appears at www.SportAviation.org .
Right: Rick Kluver’s Piper J3C-65 painted
up as a NE-1, the Navy’s version of the
L-4. His NE-1 isn’t knock-kneed, it’s justthat the port ski has stuck with its nose
in the same position it was in while the
Cub rested on the ground. When a ski
is stuck in this way, while it’s not the
preferred way to have a ski hang up,
all is well as long as a “wheel landing”
isn’t attempted. Normally, a length of
cable and bungee cord will keep the
tips slightly up in relation to the centerline of the air-
plane, like the position of the starboard ski.

Friends of the Red Barn 2 12Friends of the Red Barn 2012Each year at EAA AirVenture Osh-
kosh the largest single space for the
display of enthusiasts’ aircraft is theVintage parking and camping area.For four decades it’s been not only apicturesque scene of the finest restoredairplanes in this country, but also agathering place for aviation people andtheir magnificent machines to shareknowledge and friendship.
Each day during the convention, weget to see the widest variety possible ofairplanes, including a few one-of-a-kindaircraft. Don’t forget the special TypeClub parking area, where we host manyexamples of a particular manufacturer’sairplane. From replica race planes tothe American Barnstormers Tour, theamazing colors and outlines of thegolden age of aviation are on displayfor all to see each year. All of this is pos-
sible through the efforts of the nearly500 VAA volunteers, the volunteer VAAboard of directors, and the VAA staff.
Their passion is what makes it agreat place to be throughout the weekof AirVenture, and it’s why so manyvisitors and aviation enthusiasts comeback year after year to work, relax, andenjoy aviation’s premier event. It’s a
place to rekindle old friendships andmake new ones. A time to relax andenjoy aviation, learn something new,and rub elbows with our fellow aviators.As you can imagine, it takes some fairlysubstantial financial resources to under-write such an event, and the Vintage
structures. There’s never a shortage ofwindows that need caulking, doors
that need to be replaced, and roofsthat need to be repaired. To be cer-tain, almost all of the labor involvedis performed by our dedicated andtalented volunteers, but what aboutthe cost of supplies and hardware?
That’s where our Friends of the RedBarn campaign comes in—it providesall of us, who wish, the opportunity toassist in the vital financial support ofthe VAA’s activities.
We’re most appreciative of thecontributions made by hundreds ofVAAers who see the tangible benefits ofsupporting their fellow VAA membersin this manner. As a critical part of theVAA budget, the fund pays for suchdiverse items as VAA awards presentedduring the annual EAA Vintage Aircraft
Awards program, special recognitionfor our many volunteers, and expensesassociated with our special displays, fo-rums, and educational areas such as theVAA Workshop and Type Club areas inthe Vintage Hangar.
Your annual contribution made inthe first half of 2012 will directly ben-efit this year’s convention activities and
VAA programs throughout the year.Please consider actively participat-
ing in the 2012 VAA Friends of the RedBarn Campaign. Your donation may betax-deductible to the extent allowed bylaw, and you can enhance your partici-pation if you work for a matching gift
AirVenture Oshkosh. From parkingairplanes to feeding people at the Tall
Pines Café and Red Barn, volunteersdo it all. Some may ask, “If volunteersare providing the services, where isthe expense?”
Glad you asked. The scooters for theflightline crew need repair and batter-ies, and the Red Barn needs paint, newwindowsills, updated wiring, and othersundry repairs, plus we love to care forour volunteers with special recognitioncaps and a pizza party. The list reallycould go on and on, but no matter howmany expenses we can point out, theneed remains constant. The Friends ofthe Red Barn fund helps pay for theVAA expenses at EAA AirVenture, andit’s a crucial part of the Vintage AircraftAssociation budget.
Please help the VAA and our nearly
500 dedicated volunteers make this anunforgettable experience for our manyEAA AirVenture guests.
Your contribution now really doesmake a difference. There are seven lev-els of gifts and gift recognition. Thankyou for whatever you can do.

A gleaming new Travel Air Model 3000 (C-5427,
s/n 516) climbed aloft in the summer skies
above Wichita, Kansas, for its first flight in
1928. Powered by a water-cooled, 8e-cylinder
Hispano-Suiza “Hisso” Model E 180-hp engine,its wings embraced the sky as its “elephant-ear”
ailerons created a distinctive silhouette on the tips of its 34-
foot, 8-inch wingspan (lower span 28 feet 8 inches). The new
three-place biplane measured 24 feet, 3 inches from its wood
prop to tailskid. It carried 42 gallons of fuel and could cruise at
100 mph with a range of more than 400 miles.
A perusal of this Travel Air’s records is a glance back into
familiar aviation history. The first document in its airworthi-ness file is the manufacturer’s affidavit, which states that the
airplane was manufactured on June 7, 1928, in conformity to
ATC No. 31 and was signed by Walter H. Beech and notarized
by Olive Mellor of Travel Air Manufacturing Co. Inc.
The Travel Air Manufacturing Company of Wichita, Kansas,
touted its new biplane as “typical of the proverbial brilliant
performance with dependability that characterizes all Travel Air
Biplanes” ( Aero Digest, April 1928). Two years later, the Travel Air
Company Division of Curtiss-Wright advertised the Travel Air as:“A Plane for Every Purpose—Sportsmen Penetrate the Wilds
in Their Travel Airs. In commercial flying, Travel Airs daily
ply their way over mail, transport, and business corporation
routes. They constitute a major proportion of all commercial
planes in service in the United States. And in distance and

ren – Northern California Distribu-
tor for Travel-Air” on the fuselage.
Current Caretaker
Joe Santana grew up in Sac-ramento, California, where his
neighbor first introduced him to
aviation. “He had a homebuilt Stits
Playboy at the airport, and he used
to let me sit in it,” shares Joe. “After
I soloed at 17 and earned my pri-
vate that summer, he also took me
to my first EAA meeting.”
Joe also spent a lot of time hang-
ing around a duster strip just south of
Sacramento. That’s where he started
learning about the joys of old bi-
planes and the pilots who flew them.
“Back in the early 1970s, my first air-
plane was a Luscombe, and I flew off
a strip at Clarksburg. There was a per-
son who restored dusters there, andthey were using N3N Stearmans and
Travel Airs for dusting. I used to sit
around with those guys at the shop,
and the old duster pilots used to tell
me that a 220-hp Travel Air could
outfly a 450-hp Stearman,” recollects
Joe, adding, “I really wanted to get an
old biplane, and I decided I wanted aTravel Air, because it cruises fast, flies
real well, and hauls a good load.”
Finding that Travel Air would
take a few decades, though. In the
meantime, he tried college after
high school, but just didn’t take to
scholastic bookwork very well. So
he obtained his A&P and CFI and
taught flying for a while. He workedfor a Piper dealer in Sacramento and
then started flying DC-3 freight-
ers—and even flew as a fish and
game warden pilot, using a Beech
18 to plant fish in the high Sierras.
(C-5427) was sold to D.C. Warren
Company at Oakland Airport in
San Francisco. In April 1929, the
biplane was sold to W.J. Browne
of Stockton, California, and it re-mained in the Golden State for
years. In January 1943, the biplane
landed in the hands of Harry New-
ell of Phoenix, Arizona. It stayed in
The Grand Canyon state for nearly
three decades.
In 1945, the biplane was con-
verted for use in crop dusting and
seeding. A hopper, agitator, and
gearbox were installed. The elevator
controls were modified, and a cen-
ter section fuel tank was installed.
The Hisso was removed, and a
9-cylinder, 220-hp Wright Whirl-
wind J-5A was installed (changing
the biplane to a Model 4000).
In 1947, owners Wayne J. Kem-painen and James A. Strand of
Farm Aero Service in Phoenix had
the Wright J-5A and motor mount
removed, and a Lycoming motor
mount and Lycoming R680-9 in-
stalled, along with a Stearman oil
tank and modified exhaust stack
that extended over the top wing.In February 1970, NC5427 landed
in the hands of PSA Captain Spen-
cer Nelson of San Diego. “Spence
was very well-known in the Travel
Air world as a restorer,” explains
Joe, “and he and PSA mechanics
Jim Ward and Harry Somers worked
with him to rebuild the biplane.”
After Spence died in a PSA midaircollision in September 1978, Jim and
Harry continued with their Travel
Air West restoration company. They
sold NC5427 to Leland Jones of An-
chorage [in 1983], with the agree-
strument panel of laminated birch
plywood and a new aft cockpit
panel of laminated birch and rose-
wood, as well as installing new seat
belts and a shoulder harness in theaft cockpit.
They replaced all of the wood-
work on the fuselage, and fabri-
cated new stainless steel control
cables. The biplane was finished
with Stits Aerothane in an elegant
combination of dark green on the
fuselage and cream-colored wings.
Joe took note of this handsome
Travel Air during his PSA overnights
in San Diego, and discovered that it
had already been flown 105 hours
since its restoration. He bought the
biplane from then-registered owner
Carolyn Jones of Alaska in Au-
gust 2004. “Then I flew it home to
Waynesboro,” says Joe, smiling, “andhave had the airplane ever since. I’ve
probably put 220 hours on it, flying
it mostly during the summers.”
Flight TransitionDespite his fairly extensive fly-
ing time in 2004—including 3,500
hours of tailwheel time—the insur-ance company wanted Joe to log five
hours of time with a flight instructor
in the Travel Air in order to insure it.
“It really worked out great,”
shares Joe enthusiastically, elabo-
rating, “Captain Dick Doll, who
was No. 1 on the PSA seniority list,
did some of the flying on the air-
plane when it was first restored.Dick started out flying in dusters
and raced P-51s at Reno, and I was
never senior enough to fly with
him on PSA—so I asked him if he’d
check me out. He said, ‘Yeah, sure!’

of landings. That was a real treat,
because he’s such a great guy.”
Exceptionally pleased with his
Travel Air, Joe says, “It flies great! It
lifts off around 55 mph, climbs right
out, and cruises about 95-97 mph
indicated, at low altitude. I fly final
around 55-60 mph, and it’s pretty
straightforward in a crosswind. It
originally had a skid, but now it hasa tail wheel. The 12-inch mechani-
cal brakes are original for that air-
plane and work great. They’re ‘good
enough,’ and that’s what you want
on that airplane. It burns 12 gph at
cruise and holds 68 gallons of fuel,
with 26 in the center section and 42
in the main tank. The longest leg I’ve
flown is 4 hours and 45 minutes, and
it burned about 52 gallons before I
landed—and it had 16 gallons left.”
Joe hasn’t had any maintenance
challenges with the Travel Air—but
it has had a few repairs. Incidents can
happen to any pilot, and Joe unabash-
edly admits that he “ground looped
it at Oshkosh two years ago, so TedDavis in Wisconsin repaired the lower
left wing. That was a good opportu-
nity to do some other work, so we had
the engine overhauled by Al Holloway
in California. We also discovered that
built for three” across the
country and sharing the
experience with others.
(And he’s currently trea-
surer of the Travel AirRestorers Association.) Of
course, sharing starts at
home; he’s enjoyed tak-
ing his two sons up for
early-evening flights in
the Shenandoah Valley.
(His youngest son, Peter,
has just earned an instrument rating,
and his older son, Paul, is a Black-
hawk pilot with the National Guard
in Iraq.) “The Travel Air is a great air-
plane, and we have a lot of fun with
it,” shares Joe.
His biplane was featured during
the Vintage Aircraft Association’s
centennial celebration of the first
air mail flight in the United States,which was held during EAA AirVen-
ture 2011. Though NC5427 was not
owned by Pacific Air Transport, it was
selected as an example of the type
that flew the mail. “Andrew King of
Virginia called me to see if I was in-
terested in bringing the Travel Air for
the air mail display at Oshkosh,” ex-
plains Joe, “and he was familiar with
Pacific Air Transport—their planes
were green and cream, and they did
have a Travel Air. So my airplane was
a good representation of that. We
got some original pictures of a Travel
Air 4000 that were taken at Pearson
Field, which was one of their termi-
nals in Vancouver. That’s how wereplicated the Pacific Air Transport
Air Mail graphics for the fuselage,
which we put on just for Oshkosh.”
NC5427 also enjoyed a bit of
“movie star status” during AirVenture,
about the First Women’s Transcon-
tinental Air Derby of 1929. Andrew
was aerial coordinator for the film,
and Joe was happy to participate,
along with several other antique air-plane owners.
The photo planes were a Breezy
and a J-3 Cub. Describing the experi-
ence and the film itself, Joe explains,
“Heather worked on this film, on her
own, for 13 years. She gathered un-
believable amounts of archival foot-
age about the women and the Air
Derby, and includes that in the film.
She filmed our airplanes because they
were similar to ones that flew in the
Air Derby, and that way she could in-
clude current color footage to bring
the airplanes to life for the audience.
We filmed for a couple of days, and
we each flew about three hours.”
Built for Sharing Joe has been depositing numerous
experiences in his memory bank offavorite Travel Air flights since 2004.
Though he’s enjoyed them all, there
is one particular “annual deposit”
that registers at the top of his account.
“Probably the greatest thing we do
with this airplane is taking it to the
Dirksen’s family farm in Winchester,
Indiana. The year before last, I took
three people up—and they were in
their 30s, but they had never been
in an airplane before in their life. We
go to the Dirksen’s, and their kids are
so excited to have us come, and they
treat us so well! “We get to land in their hayfield,
and the whole town comes out, and
we give rides. I mean, that’s what it’s
all about,” shares Joe exuberantly,
“and to fly with Ted Davis, Andrew

He also flies the Travel Air to
Hagerstown, Indiana, for an-
other fun gathering—the “Hag-
erstown Or Bust” Ford Model T
and vintage airplane fly-in. “Lit-
erally hundreds of Model T’s
from across the country show
up there on the fairgrounds,
and they have a nice grass field
for the airplanes,” adds Joe,
smiling, “We do a balloon bust
there, a flour bomb drop, and
Ted gives rides in the New Stan-
dard. We’ll also fly to Brodhead,
Wisconsin, and Blakesburg,
Iowa, for those fly-ins.”One thing is certain—when
the Travel Air landed in Joe’s
hands in 2004, it found a very
good home, indeed. It flies reg-
ularly, and continues bringing
joy not only to its caretaker, but
to many others across the coun-
try. And it’s still pleasing to thediscerning eyes of aircraft judges
at fly-ins. That’s quite under-
standable, since NC5427 still
looks like it’s fresh out of resto-
ration—even though it’s been
20 years. This handsome bi-
plane received two awards to its
credit this past year: the Silver
Age (1928-1936) Champion—
Bronze Lindy at EAA AirVenture
Oshkosh, and the Travel Air
Type Club Award at the Antique
Airplane Association’s annual
invitational fly-in. Joe readily
credits these awards to the resto-
ration efforts of Travel Air West

ing homage to Jim Ward and

ily, and her direct inspiration to create
the documentary arose during a con-
versation with the legendary Evelyn
Bryan Johnson in Morristown, Tennes-
see. Known as “Mama Bird,” Evelyn haslogged 57,635.4 hours of flight time.
Heather had the opportunity to meet
Evelyn, and recalls asking her a few
questions about the races and how they
began. “As she talked,” says Heather,
“something just clicked inside of my
gut, and I knew this was the story I had
been looking for.” Heather embraced
her own challenge and resigned from
her position with Discovery Communi-
cations in mid-2007, in order to devote
her full-time energy to the task.
Filmmaking can be a tedious un-
dertaking. In Heather’s case, it was
similar to a first-time aircraft restorer
tackling a ground-up restoration.
Heather shares that the most sig-nificant challenge she encountered
while creating this film was likely her
own confidence—or lack thereof.
“I had been in the industry over
a decade, had a master’s in produc-
ing film and video, but I had never
produced my own film,” she admits,
adding, “The other significant chal-
lenge was finding the right people
to help work on the film. But in the
end, I met some incredibly talented
and gifted people and am grateful for
what they brought to the project.”
Though there were times when
Heather really didn’t know how she
was going to achieve her goal, that
wasn’t a deterrent—in fact, it turnedher personal resolve into tangible ac-
tion. “I’d never written a script…and
[eventually realized that] I had to be
the one to write the film. [Another
challenge] that took years to work
lected by Aerial Coordinator Andrew
King as representative of the types
flown in the 1929 Air Derby: 1928
Travel Air 4000 (Joe Santana), 1929
Speedwing Travel Air B9-4000 (BillPlecenik), 1930 Monocoupe 90 (Bob
Coolbaugh), 1928 Monocoupe 70
and 1929 Waco GXE (Paul Dough-
erty), and 1930 Fleet 7 (Mike O’Neal).
Ever attentive to detail, Heather
ensured that when the audience sees
archival footage of Louise Thaden’s
Travel Air flying, they hear a Wright
J-5 engine and not some other en-
gine—and she did this as closely as
possible with each aircraft.
Watching this documentary makesit easy for viewers to feel as thoughthey have been personally intro-duced to each of the featured women
pilots. The transitional graphics weretastefully done, the clips of the origi-nal pilot licenses added even morehistorical detail, and the personal in-
terviews (especially with Pat ThadenWebb, Margaret Whitman Blair, andElinor Smith Sullivan) added greatdepth to the documentary.
Heather offers a bit more insight to
the film, and her own personal phi-
been given talents and gifts, and it is
our responsibility, in my opinion, to
nurture, develop, and explore those
interests, no matter how irrational
it may be. To do so means givingback to the world and making it a
better place. The women in 1929 did
this with gusto. I can only hope that
by exploring my interest in these
women and bringing their story for-
ward, it will inspire others to take a
risk of their own and contribute to
the world in their own unique way.”
Most any project comes bear-ing not only cloudy challenges, butthe proverbial silver linings, as well.Heather thoughtfully reflects, “Oneperspective I gained in researchingall about these women is that ratherthan seeing them as icons or legendsper se, I realized they were just people
too, doing something they felt calledto do, and they went and did it. In theend, I love…learning from those whohave overcome their own personalobstacles to achieve something.”
Heather eloquently sums up her
unique mission in creating her film
company, Archetypal Images, with the
following statement: “…to produce
films that explore and harness that
light in the eyes of people who have
found their calling in life, and share
that sparkle with others who are still
searching to find their own passion.”It is clear that Heather has discov-
ered her own calling in life, and her
passion for accuracy and authen-
tic detail was the catalyst for herto achieve excellence in her work.

At any gathering of sport planes,
one is likely to see at least a few
monoplanes of the “parasol” type.
Old-timers will have seen so many
of them that they’re likely to take
them quite for granted. And new-comers often have such scant
knowledge of aviation’s long and in-
volved history that to them a Loehle
Parasol or Baby Ace is likely to be
just another of a thoroughly bewil-

ries by Joseph P. Juptner, and the
Aircraft Yearbooks by the Aeronauti-
cal Chamber of Commerce. I wasquite surprised at the large number
of parasol types I found pictured
and described in these old books.
While many were obscure types, all
were interesting to study with the
question in mind, “Why did the de-
signer do what he did?”
A parasol monoplane is one on
which the wing is mounted above
and more or less clear of the fuse-
lage. The word is derived from the
Italian parare, meaning “to ward
off,” and sole, meaning “sun.” A
lady’s parasol wards off the sun.
Because a wing above the fuselage
wards off the sun, the French seem
to have been the first to apply theword “parasol” to airplanes. Fig. 1
shows a parasol monoplane built
by Henri Farman in 1910. He was
famous for his biplanes—perhaps
he cobbled up this parasol to learn
wing configurations were popular
because these arrangements lent
themselves to effectively arrangingthe many rigging wires needed to
achieve structural rigidity.
quent crashes of those days, pusher
engines could tear loose and fly for-
ward onto unfortunate airmen.
Parasol monoplanes provided
the answer. Fig. 2 shows a German-designed, Austrian-built Albatros of
1914. The good downward visibility
is obvious. Note also the many brace
wires. Bleriot and Morane Saulnier
in France brought out similar-looking
designs, and two-seaters from the
latter company were used by the
French throughout that war.
As the outcome of several inci-dents of the wings of wire-braced
monoplanes collapsing under the
strain of combat flight, other coun-
tries such as Britain stayed with the
more rigidly trussed biplanes. Seek-
ing more speed from available en-
gines, late in the war the Germans
developed monoplane fighters suchas the Junkers and Fokker Triplanes.
The latter had its cantilever wing
mounted parasol-fashion above the
fuselage to put it out of the way of
aiming forward-firing machine guns.
As the result of aerodynamic re-
search begun during that war and
carried on into the 1920s, thicker
airfoils came into general use. These
allowed the use of deeper wing spars,
so multiple brace wires below and
above parasol wings gave way to
simpler, cleaner wing struts running
from fuselage lower longerons out to
fittings on the undersides of wings.
Strut-braced low-wing mono-
planes were also built but had dis-advantages. Struts running from top
longerons to fittings on the upper
surfaces of wings disturbed airflow
and hurt wings’ lifting qualities.
Some low wings had struts running

facturer built military observation
and fighter planes of this type be-
cause of good visibility and simple,sturdy construction. When twin
machine guns were mounted in fu-
selages, it was necessary to use in-
terrupter mechanisms to halt their
firing when propeller blades passed
in front of the guns. Some 1920s
parasol fighters moved the guns
outboard to where struts met the
undersides of their wings. Fairings
enclosed the guns and at the same
time cleaned up the airflow where
struts met the wings. This allowed
uninterrupted and therefore more
deadly gun firing.
The more designers studied para-
sols, the more advantages they dis-
covered. As originally produced,the sleek 1927 Lockheed Vega, Fig.
3, was a high-wing cabin mono-
plane. Western Air Express liked
its speed but found things to com-
plain about. The cantilever wing’s
headroom. Because of its shape,
the single pilot’s seat up forward
intruded into cargo space at the for-ward end of the cabin. Pilots felt
it would be hard to get out of the
enclosed cabin should they have to
take to their parachutes. In a crash,
the cargo would come flying for-
ward onto them.
Lockheed engineers realized the
Vega’s wooden wing and fuselage
could easily enough be revised to
create the parasol Air Express. Rais-
ing the wing clear of the fuselage
got its deep spars out of the cabin
headspace. Cargo area was increased
at the front end of the cabin. Prob-
ably lift was increased by separating
the underside of the wing’s central
portion from the fuselage, thus in-creasing the amount of working
wing area. Accustomed to open-
cockpit biplanes, pilots had no trou-
ble with poor forward visibility in
the rearward-located open cockpit.
ier and faster. Their weight so far aft
balanced the extra 200 pounds of
the 425-hp Pratt & Whitney enginethat replaced the original Vega’s
220-hp Wright Whirlwind. When a
mixed load was to be carried, cargo
could be loaded into the front of
the cabin with passengers behind
it, affording them the best possible
safety in a crash.
This mention of the Air Express
brings out the point that the para-
sol configuration lends itself to the
simple and clean installation of
one-piece wings, either strut-braced
as in the Pietenpol, Fig. 7, or can-
tilever as on the Potez 60, Fig. 19.
Such long wings can be awkward
in a homebuilder’s basement shop,
but in factory-built planes save theweight and cost of center section
fittings. Cutouts in the top or bot-
tom of a fuselage are not needed.
Because the weight of the fuse-
lage, engine, occupants, and land-

but str ucturally was a parasol. Its layout facilitated cockpit access. Small engine on long nose balanced pilot’s

wing, what is called “pendulum sta-
bility” is good. Looking at a parasol
monoplane from ahead or behind,
it’s easy to visualize how all this
weight below the wing will act torestore an upset plane to level at-
titude. But it’s easy to place more
importance on this than is justified.
If it has been well-designed and its
pilot is normally alert, a low-wing
plane will not suddenly roll over
upside-down.
However, it’s not as well-known
as it deserves to be that parasols arevery good in regard to longitudinal
stability. That is valuable in respect
to behavior in steep climbs, stalls,
and turbulent air. In Fig. 4A, note
the relationship between the cen-
ter of gravity (CG) and the center
of lift (CL) in this parasol in level
flight. It is standard practice to po-sition the center of gravity ahead
of the center of lift and to balance
a plane with a download on the
stabilizer. An appreciable nosing
down-force, D, is then present.
When the engine is throttled or
quits, the plane will automatically
nose down and begin to glide. In
this drawing, the center of gravity’sforward position has been exagger-
ated in the interests of clarity.
As this parasol noses up, Fig. 4B,
the wing sort of “rotates” backward.
This shifts the center of lift back-
ward, too, and the force D becomes
stronger. More backward stick force
is needed to hold the nose up,which is a desirable characteristic.
In level flight, a low-wing as in
Fig. 4C has about the same force
arrangement. But when it noses
up, due to its lower position the

powered Fairchild 22 of the early 1930s.

puzzlingly tail-heavy as to make it
rotate backward into inverted posi-
tion. This was called “catastrophic
instability.” When this appeared
while flying at low altitude, the re-sult was indeed catastrophic.
Because of this lessened nosing-
down tendency with increasing
angle of attack, low-wings can be
sensitive to load distribution, how
fuel happens to slosh back in tanks
when climbing steeply, airfoil cen-
ter of lift travel, amount of wing
dihedral (which affects the verti-cal location of the center of lift),
position and weight of the landing
gear, and so on. Ride or “feel” in
turbulent air can be “jiggly.” In-
creasing lightness of rearward stick
force when approaching the stall
can be a warning that a low-wing
is approaching catastrophic insta-bility. Now you understand clearly
why we have aeronautical engi-
neers and test pilots.
After World War I, some designers
looked for ways to improve the per-
formance of cheap, surplus Curtiss
Jennys. It’s often easy to rebuild a bi-
plane into a parasol monoplane. The
center section cabane strut fittingsare already in place, and fittings
where lower wing spars attached
to the fuselage can be reworked
if necessary to accept parasol lift
strut ends. Thick-airfoil monoplane
wings installed on Jenny fuselages
resulted in worthwhile performance
improvement and called the parasoldesign to the attention of the Amer-
ican aviation community.
While surplus Jennys were cheap
to buy, they were large and com-
plicated airplanes and thus costly

ers brought out neat parasols such
as the Davis, Fig. 9, and the Inland
Sport, Fig. 10. Open cockpits were
then still much in favor, and many
designers were still wary of low-wings. These monoplanes needed
substantially fewer wing spars/wing-
tip bows and ribs than did biplanes.
The depression that followed
the stock market crash of 1929
increased designers’ interest in
monoplanes, including parasols.
Some outcomes of this were the
very handsome Fairchild 22, Fig.5, for affluent buyers and the low-
priced American Eaglet, Fig. 13,
Taylor Cub, Fig. 14, and others for
less well-heeled customers.
To coax acceptable climb from
low-powered airplanes, it’s impor-
tant to reduce drag. Open-cockpit
parasols like the Eaglet and Cubcould be fitted with detachable
cockpit enclosures, which helped.
And, by making cold-weather fly-
ing more bearable, these accessories
boosted small airports’ income by
encouraging wintertime instruc-
tion and rentals. Merely by raising
the light superstructure atop fu-
selages, some of these ships couldeasily be changed into high-wing
cabin jobs.
In some cases it’s possible to
argue at length as to whether a
particular ship is a parasol or high-
wing cabin plane. The English
Comper Swift, Fig. 3, and Corben
Super Ace, Fig. 15, are examples.In some planes such as the Ford-
engined Pietenpol, Fig. 7, and the
Cirrus-engined Westland Widgeon,
Fig. 11, the carburetors were posi-
tioned so high that in order to ob-

carrying angles for the various
struts. In some parasols such as the
smallish Pietenpol, the vertical space
between fuselage top and the lower
surface of the wing was just scant
enough to make front cockpit entry
and exit a problem. Pilots instructed
passengers in a well-thought-out en-
try and exit procedure. Glued wood-
to-wood joints are not as strong as
are welded ones in steel tubing, and
a fuselage is basically a beam that
carries engine weight in the front
and elevator up-and-down loads atthe rear end. To avoid discontinuity
in a wooden top longeron caused by
a cockpit door cutout, designer B.H.
Pietenpol did not incorporate a door
in his Air Camper’s fuselage. Large
people or ones having arthritic
knees sometimes could not get into
a Piet. But the welded steel tube con-struction popular in the fuselages
of factory-made parasols made the
incorporation of door openings a
simple matter.
Some parasols had their wings
mounted as high as their designers
dared, such as on the Ross RS-1, Fig.
6, to facilitate entry and exit. But
this could bring on a tendency totip easily in crosswind landings. In
those days flying was often done
out of farm fields, which allowed
taking off and landing into the
wind all the time. But the high-
winged, narrow-geared Ross could
be a problem on a modern airstrip
during crosswind conditions.The Czech Letov, Fig. 8, had an-
other approach to front cockpit
access—this cockpit was located
ahead of the wing. It worked, but
put pilot and passenger unhap-
few Pietenpols had hinged flaps in
the trailing edges of their wings.
These helped cockpit access yet
retained unbroken trailing edge
shape in flight.
The 1929 Davis had a double-
tapered wing employing box spars
that were deepest at the point of
wing V-strut attachment and ta-
pered both toward the tips and the
center section as yet another way
of improving cockpit access. This
design also kept the struts short so
as to make them stiff and compara-tively light, and also to reduce drag.
Yet another cockpit access solu-
tion was to use swept-back wings
as in the Kaminskas aerobatic para-
sol, Fig. 17. This puts the center
section ahead of the cockpit, while
the sweepback positions the wing’s
center of lift where it has to be forproper aircraft balance in flight.
Many military parasols used this
configuration to keep the center sec-

cilitate quick exit should it become
necessary to take to parachutes.
French air show pilots favored
Morane Saulnier and Dewoitine
parasols for yet another reason.
When going upward at the begin-
ning of a loop, one sees only empty
sky in front of the plane’s nose.
Then as one goes over the top and
starts down, the center section of a
parasol (or biplane) facilitates judg-
ing attitude in relation to the up-
side-down horizon.
We could say many more things
and print twice as many photos, ifspace permitted. But what we’ve
been able to cram into the avail-
able space should be enough to
help you to learn how to under-
stand and evaluate parasol mono-
planes. The type is very old, but
will be with us for a long time to
come because of its versatility andadaptability to various sport flying
requirements. Why, when rain-
storms disrupt activities at fly-ins,
people even scurry to get under the
wings of parasol monoplanes!

Defects in wood structures are critical, and inspec-
tion techniques must be developed to locate and iden-
tify these structural problems. This data is important to
new mechanics who may not be familiar with inspect-
ing wood structures, particularly wood wing spars.
This is important when inspecting wood spars inAeronca, Bellanca, and Champion aircraft. FAA Air-
worthiness Directive 2000-25-02 R1 in particular re-
quires close inspection of wood wing spars installed in
Aeronca 7 and 11 series aircraft and Bellanca Citabria
acrobatic aircraft.
One would think that a 65-hp Aeronca Champ or
Chief would not experience compression failures in
wing spars, but I have seen this defect and feel it is im-
portant to expand on the airworthiness directive be-cause compression failures are difficult to locate, and
in the case of the Champ and Chief, are often mostly
hidden because they will form under a wing rib that is
nailed to the spar at a critical location.
American Champion Service Bulletin 406 Revision
A gives detailed information on the subject. These
compression failures can happen if the aircraft ground
loops and the wingtip strikes the ground, or they canbe caused by over-stressing the spar when pulling
some g ’s performing spins or other semi-aerobatic or
aerobatic maneuvers.
A compression failure is defined as a break across
grain lines of the wood caused by very high compressive
dent occurred. This type damage may have happened
when the tree was cut and it fell across another tree or
a large rock, which fractured the entire log. In-service
compression failures will normally appear on the top
flange of the spar, and in the case of Aeronca and Bel-
lanca spars, directly adjacent to a plywood plate in-stalled at the front and rear strut attachment point.

spar flange carries a tension load. Therefore, any crack
across the grain lines can be dangerous, and if not de-
tected, it can lead to complete failure.
Illustrations 2-4 are three photos that show a com-
pression failure I found on a Bellanca 7ACA. Illustra-
tion 2 is the back side of the front spar. The bright
wood to the left of the photo is where a plywood rein-
forcement plate was glued to add strength where the
front lift strut attaches. To the right of the photo is out-
board of the plate and the typical spot where a com-
pression failure will form.
The lines are made with a pen to highlight the de-
fect. There are some interesting items to observe here.
First the crack goes into the upper nail hole that holdsthe aluminum rib to the spar. The failure is under the
wing rib and therefore impossible to visually locate.
The failure is about 25-30 percent of the spar width.
That is almost a total failure of the upper spar flange.
Illustration 2: Bellanca 7ACA, back side of the front spar.
Illustration 3 shows the view looking down on the
top of the spar; the crack is clearly visible. This is the
only location to spot a compression failure at this loca-tion on the Aeronca and Bellanca series airplanes. The
American Champion Company states that an opening
should be cut into the fabric to inspect this area to fa-
cilitate complete inspection.
It will be necessary to remove a small segment of
aluminum leading edge to gain complete access to this
area. In this view it is very evident as to the defini-
tion of a compression failure—a jagged crack across the
grain fibers.
Illustration 4 shows the compression failure on
the front side of the spar that has progressed to 15-
20 percent of spar width. I took these photos after
the spar was removed from the wing in preparation
to installing a newly fabricated front wing spar. The
bright wood to the right was where a plywood plate
was glued to support loads at the front lift strut
attach point. To the left of the photo is outboard
to the wingtip. There are two parallel pencil linesto allow proper positioning of the wing rib before
nailing to the spar. Again, note that the failure is
under the rib.
Illustration 4: Compression failure on the front side of the spar.
Illustration 5 shows two inspection openings on the
top of the front spar of my Champ wings covered in
Poly-Fiber through silver. These openings comply withthe recommendations in SB 406, Revision A. When the
wings are finished, aluminum covers will be screwed in
place and sealed with a soft rubber gasket so moisture
will not penetrate this critical area.

When re-covering a set of Bellanca 7ECA wings, Ifound a compression failure in the rear spar at the in-
board aileron attach point. Unfortunately I do not
have a photo of that failure.
Shakes and checks are also on the critical inspec-
tion list. Shakes are identified as cracks. Shakes and
checks normally can be found at spar ends and are
due to moisture entering the wood and causing it to
swell. Spar ends are susceptible if the grain is not com-pletely filled with varnish—filling the end grain nor-
mally takes additional coats of varnish because the
varnish will penetrate the grain structure and be drawn
into the wood fibers.
Shakes are defined as a longitudinal crack along
jor fittings such as lift struts and streamline wire at-
tachment points. There are times when a shake that
begins at the end of a spar will progress outboard and
will exit the plywood doubler and form itself into a
longitudinal crack. AC43.13-1B states that most lon-
gitudinal cracks can be repaired by gluing on plywood
plates on both sides of the spar; however, to adequately
inspect the spar and glue on such plates, the wing has
to be uncovered, and most mechanics will opt to re-
place the entire spar or splice in a new section through
the damaged area.
This final illustration is interesting from the stand-
point of visually inspecting damage. Look closely at
the photo in Illustration 7 and you will see two distinctfailure modes in wood. First, half of the thickness of
the spar has failed due to compressive forces, while the
other half has failed due to tension forces. How could
this happen, except in an accident? Well, back in 1970,
that is what happened to the pilot of a CallAir A-9 agri-
cultural airplane. While spraying next to his house, he
decided to make a pass over the home to wave at his
wife. In a steep left turn, he put the wing into a largetree in his front yard and tore off the outer 6 feet of the
front wing spar. He was able to fly back to his strip and
land safely, and I was called to make a repair without
removing the wing from the airplane.

Today was a great day for this old tail-
wheel flight instructor. One of my stu-
dents took and passed her checkride and
is now a bona fide pilot. Now, that isn’t a
big deal nor different from most anyone
else receiving a pilot’s license. But this
one was special to me.
About 18 months ago she and her husband came
to me. He was already a pi-
lot, and up until this day she
was a very good navigator/
passenger. But on this day
she wanted to begin taking
flight lessons. I thought this
wasn’t anything unusual;
over the years I’ve workedwith a number of spouses
who wanted to learn to fly.
In this case , however ,
the situation was a bit more
challenging. This couple had
previously restored an air-
plane together, he doing the
structural work and she do-ing the fabric. Together they
flew it all around the area,
proudly showing the plane.
Then together they began
another aircraft restoration.
uncomfortable with whatever we were doing, she
was to tell me so.
The first lesson began with a 30-minute session
taxiing a tailwheel airplane around the ramp area
and then out to the runway, learning the S-turn
method of taxiing while doing so. Quite tentative at
first, she soon acquired the feel for the airplane, at
least on the ground, and relaxed somewhat.
The first step of confidence-
building now accomplished,
we aligned the airplane with
the turf runway in preparation
for the takeoff. While explain-
ing the control stick position
and movement, I could feel
her tension building. Her gripon the Cub’s control stick was
like a vise. To break the ten-
sion I told her I could take her
pulse simply by placing a fin-
ger on top of my control stick.
She laughed and relaxed, but
only just a bit.
Throughout the late summerand early fall we flew weekly.
Each new maneuver was a
challenge, not because it was
difficult for her to master but
rather because of her anxiety.

For example, I would ask her to demonstrate a
steep 360-degree turn to the right or left keeping
the altitude within plus or minus 200 feet. Once
that was accomplished we would tighten the pa-
rameters to 100 feet, then 50 feet, and finally 20
feet. Using this method, she learned to relax a bit
more, yet she strived for perfection with less self-
induced pressure.
When the cold weather and snow finally arrived, we
decided to put further training on hold until spring.
Spring 2011 arrived, and we resumed our flight
training. It was now time to work in the traffic pat-
tern in preparation for solo. Lack of self-confidence
again surfaced, but with encouragement and regularreminders to relax, progress was made. Finally, it
was time for me to get out of the Cub and turn her
loose for three takeoffs and landings. She argued at
first that she wasn’t ready, but I convinced her that
she was. Each of the three takeoffs and landings were
near perfect.
When she taxied back to the hangar following
that first solo, the grin on her face was spectacular!
She had transformed from someone afraid of touch-
ing the controls to being able to safely and confi-
dently fly the airplane solo! What a milestone. After
the traditional cutting of the shirttail, I asked how
she felt, and she responded by telling me that her
butt cheeks were so tight, she thought the seat cush-
ion was still there!
Crosswind takeoffs and landings were next on
the agenda, and these came to her almost naturally.Within two hours she had mastered the technique
and was ready for the dual and solo cross-country
phase. At this point I strongly pushed for getting
her written test taken. She had been procrastinating,
thinking that she wasn’t ready to take and pass the
exam. I set a deadline of the next Friday. If she didn’t
have the test taken by then, we would postpone the
planned dual and solo cross-country flights.Pressure now dutifully applied, she accepted the
challenge. I’ve found over the years that setting
deadlines helps students move forward. She called
me on that Friday afternoon and in an excited voice
explained that she had achieved a 90 percent on the
to schedule the checkride for the following Saturday.
I spoke with her several times during the week
preceding the flight test. Each time it was to bolster
her courage and confidence. Nervous, yes, but she
was prepared. Finally, checkride day was here, and
I think she arrived at the hangar at 5 a.m. for the 9
a.m. appointment. For several hours she paced the
hangar, reviewing everything in her mind. The per-
fectionist in her rose to the surface once again.
Once the designated examiner arrived and the
oral portion of the checkride began, she relaxed a
bit. The examiner quite understood and helped put
her at ease. The remainder of the checkride went
without a flaw, and the examiner commented so.Finally, with the new piece of paper in hand
proclaiming she was a real pilot, she finally be-gan to unwind, but not without a lot of kiddingand congratulations.
I’ve been providing flight instruction for 40 years
and have worked with a number of students, but this
student and her accomplishments were very special
to me. With great pleasure I watched her transform
from a position of timidity and anxiety to one of
self-confidence and achievement.
It proves that anyone with a real desire can over-
come most any obstacle, learn to fly, and enjoy the
pleasure of flying!

try was gradually replacing wooden-spoked wheels with pr essed-steelwheels. In order to sur vive, HayesWheels and Forgings needed to de-
velop new products.It so happens that both the c om-
pany’s general manager and chief en-gineer, William Kistler and Norman A.Thompson, were aviation enthusiasts.Kistler, who seemingly never soloeddespite many hours of training, ownedan airplane, an Arrow A-2 Sport two-
seat light biplane. Tompson, who hadflown with the Royal Flying Corps andRoyal Air Force during the Great War,owned a Lincoln Page LP-3 light biplaneas well as a private airfield and hangarnear Chatham. One day, the LP-3 wasseriously damaged in a crash causedby a frozen fuel line. Eager to y again,Thompson took the welded steel tubefuselage to a local automobile mechanicand talented welder, Philip Alexander.Putting the Lincoln Page back into yingcondition proved relatively easy, whichgot both men thinking. If money couldbe found, it should not be too compli-cated to design and build an airplanefrom scratch. Kistler readily agreed to -
nance the project. Here, he thought, wasa new type of product that could restorethe fortunes of Hayes Wheels and Forg-ings. Te airplane would be produced bya subsidiary, a manufacturer of woodenwheel hubs and spokes, W. & O. McVeanof Dresden, Ontario.(Te McVean family had arrived in
Dresden around 1870, and it domi-nated the local business communityfor almost half a century. Its patriarch,
Alexander McVean, was a close friendof Canada’s first prime minister, SirJohn A. MacDonald. Two of his sons,
somewhat heavier than planned, the Valkyr V-2 proved remarkably suc-cessful and easy to fly. Sadly, no oneshowed much interest in the new de-
sign. Airplanes like the de HavillandMoth, the Avro Avian, and the Curtiss-Reid Rambler were already flying inCanada in some numbers. Registeredwith some difficulty as CF-AKP onMay 14, 1930, by O. & W. McVean, the Valkyr V-2 was sold to Alexander inOctober 1933. Its pilot throughout the
1930s was Ernest H. Taylor, a youngaviation enthusiast who had drawnmany of the ttings and componentsof the airplane. Grounded followingthe outbreak of the Second World War,CF-AKP was destroyed by a hangar rein 1940 (some sources say 1946).
Design of another airplane begansoon after the rst ight of the Valkyr
V-2. Larger, heavier, more powerful,and better equipped than its predeces-sor, the Valkyr V-3 was a three-seater(two side-by-side seats at the frontand a single seat further back). Thisconguration had proven very popular
nated the project. Convinced that thenew airplane had potential, Thomp-son, Taylor, and Alexander asked thatthe uncompleted airframe be turned
over to them. Tis was soon done, andconstruction started anew at Tomp-son’s aireld, near Chatham.Te Valkyr V-3 was registered as CF-
AQA on February 19, 1931, again withsome difficulty, by O. & W. McVean.Thompson test flew the orange andbrown biplane around Easter. He quickly
realized that the airplane’s flying char-acteristics were not as good as those ofits predecessor. Enlarging the rudderhelped, but did not solve everything.Rumor has it that the Valkyr V-3 wouldgo into a steep dive after being stalled.Worse still, control could only be re-gained after a considerable loss of height.
In September 1931, both Valkyrstook part in a 450-mile air rally, theTip Top Aerial Derby, sponsored byTip Top Tailors of Toronto, Ontario.More than 20 airplanes, includingboth Valkyrs, completed this race. Te Valkyr V-2 actually came in third.
As the economic depression deep-ened, Hayes Wheels and Forgings’

should not be toocomplicated to design

situation grew worse and worse. Iteventually closed down all operations.In May 1936, G.B. Stewart and C.W.Burgess of Dixie, Ontario, submittedbut did not complete an application to
certify the airplane. M.J. Wilson of Cha-tham bought CF-AQA later that yearbut did not complete the certificationprocedure. Frank H. Armitage of Ham-ilton, Ontario, bought the Valkyr V-3at a public auction in August 1936. Tefollowing year, the 165-hp Continen-tal A-70 engine suffered a midair fail-
ure. Armitage chose to replace it witha 200/220-hp Wright J-5 engine. TomSenior of Brantford, Ontario, boughtCF-AQA, possibly in late 1937, and cer-tied the airplane in January 1938. Be-fore long, he realized the Valkyr V-3 wasin rather poor shape and decided to dis-pose of it. Over the next few months,Senior apparently sold the airplane twoor three times, but the buyers soon re-turned it—and presumably asked fortheir money back.
Senior finally sold CF-AQA to R.M. Armstrong who certied the airplane inJuly 1939. Tis young miner and inex-perienced pilot from the Levack minesnear Sudbury, Ontario, soon contacted
another pilot and experienced amateurairplane builder by the name of L.A.Hottie. Armstrong wanted to know ifHottie could make the Valkyr V-3 air-worthy again. He could indeed.
On November 6, 1939, the Valkyr V-3 stal led while performing somelow-level aerobatics near Larchwood,Ontario. It spun into the ground. Arm-strong and his passengers, G. Lennox
and F. Church, were killed instantly.It is worth noting that Ernest H.
Taylor later worked for Victory Air-craft at Malton, near Toronto, duringthe Second World War;
