3. Number Required for Dispatch MAINTENANCEPROCEDURES

OPERATIONALPROCEDURES21 - Air Conditioning 4. Remarks and Exceptions

10-1 Engine Main Air Valves C 2 1 (M) (O) One may be inoperative for pressurized flight provided;

a) Valve is secured closed, and b) Flight Deck Heat Valve System is

operative.

1. Verify affected valve mechanical indicator arm is secured closed.

2. Pull and collar the affected MAIN AIR VLV circuit breaker.

3. Disconnect electrical connector from valve, bag, and stow.

With engines running, select AUX HEAT (F/DK VLV) and confirm that airflow is present.

C 2 0 (M) (O) May be inoperative provided:

a) Both valves are secured closed, b) Ram Air and Dump Valve, or Vent

Valve (Post Mod. 25G726A/C) are verified operative before the first flight of the day,

c) DUMP VLV, or VENT VALVE (Post Mod. 25G726A/C) is selected OPEN,

d) Flight is conducted in an unpressurized configuration,

e) Aircraft is operated at or below 15,000 feet MSL, and

f) Applicable Oxygen requirements are established and complied with.

1. Visually confirm valve mechanical indicator arms are in the closed position.

2. Pull and collar the affected MAIN AIR VLV circuit breaker.

3. Disconnect electrical connectors from valves, bag, and stow.

Reference Table 1, ConfigureAircraft for Unpressurized Flight.

10-2 Engine Main Air Valve Position Indicators

C 2 1 (O) One may be inoperative provided both engine main air valves are operative.

With engines running and APU OFF,a) Sequentially select L & R Main Air

Valves OPEN and CLOSED.b) Confirm that airflow is present with

valve OPEN and that flow stops when valve is closed.

C 2 1 (O) One may be inoperative provided indicator associated with the operative main engine air valve is operative.

With engines running and APU OFF,1. Select operative Main Air

stall detector vent.

2. Confirm that No.6 static vent orifices on each static vent plate are clear of obstruction.

3. Energize PE busbar.

4. At the pitot head connection, apply sequentially the pressure (P) values given in Table 2, and in each case slowly increase pressure (V) to the stall detector vent until the stick shaker motor operates. Note V pressure at each point.

5. Verify that V pressures meet requirements of Table 2, and then release pressures.

NOTE

Table 2 provides a V/P ratio of 0.71 ± 0.02 on increasing pressure, when checked using Millimeter(s) (mm) water.

NOTE

When A.S.I. gauges (calibrated in knots) are used as alternative to mm water gauge, the readings will not provide the same ratio as mm water to knots as conversion is not linear. Reference Check Pressures Table 2.

6. Remove test set connection from pitot head and apply increasing pressure to stall detector vent until stick shaker motor operates. Maintain this vent pressure, reconnect test set to pitot head and apply increasing pressure (P) until warning system cuts out. Verify that, at cutout, the pressure (P) was between 76.5 and 86.0 mm water (70 ± 2 knots). Release pressures.

7. Disconnect and remove test sets.

PROCEDURES

Perform the following procedure to bypass the LH and RH Flap Bias Switches:

1. Ensure power is removed from aircraft.

2. To bypass LH Wing Flap microswitches:

• Remove 2nd (from the rear) overwing access panel on LH side, using quick release fasteners.

• Locate terminal block JBA, remove nut from JBA8, and remove the wire marked A8JB:W1:55:W1:JD3L. Stow wire to safely isolate the 15/45 Flap LH microswitch.

• Remove nut from JBA7, and remove the wire marked A7JB:W1:55:W1:P1N from JBA7 and place on JBA8. This isolates the 0 Flap LH microswitch and provides 28V to the SSU 1.

• Replace nuts on JBA7 and JBA8 terminal blocks and replace overwing access panel.

3. To bypass RH Wing Flap microswitches:

• Remove 2nd (from the rear) overwing access panel on LH side, using quick release fasteners.

• Locate terminal block KB, remove nut from KB8, and remove the wire marked 8KB:W2:55:W2:KD4L. Stow wire to safely isolate the 15/45 Flap RH microswitch.

• • Remove nut from KB7, and remove the wire marked 7KB:W2:55:W2:P2N from KB7 and place on KB8. This isolates the 0 Flap RH microswitch and provides 28V to the SSU 2.

• • Replace nuts on KB7 and KB8. terminal blocks and replace overwing access panel.

4. Power up the aircraft and check that the SSU Fault light and the STALL IDENT light are not illuminated.

system exists which would adversely affect operation of the airplane, and

b) A procedure is established and used to ensure that the associated thrust reverser(s) is disabled and pinned in the stowed (forward thrust) position.

Refer to Table 1 for maintenance procedure. 1. Confirm that the associated (M) procedure for disabling thrust reverser(s) in the stowed position is accomplished, and

2. Confirm that no apparent damage to the thrust reverser system exists which would adversely affect operation of the airplane, and

3. Plan flight to ensure that safe landings can be made at the airports to be used with the thrust reverser(s) inoperative (INOP).

Note

Care should be exercised when advancing single reverse thrust to avoid controllability effects.

For NORDAM (Dee Howard) Clamshell Thrust Reversers, perform the following steps: a) Verify that the airplane bus bars are de-energized and that no external electrical power is connected. b) Open and collar the Thrust Reverser (TR) circuit breakers (Refer to Table 2). c) Remove the outboard fairing from each TR. d) Verify that the TR’s are stowed and latched. e) On the outboard of each engine install the two latch lock pins through the latch box cover and the latch box.

NOTE

It may be necessary to remove the lockwire from the bolts in the latch box.

f) Attach the two latch lock pins with screws. g) Lockwire the bolts in the latch box and route the wire over the lock pins. h) Inspect visible operating mechanism for evidence of damage. i) Install the outboard fairing to each TR. j) Put a warning placard over the annunciators in the flight compartment reading, ‘THRUST REVERSER INOP’.

For Aeronca Cascade Thrust Reversers, perform the following steps: a) Remove the inboard and outboard pneumatic latch access panels.

NOTE

Before the inboard access panel can be removed, the detachable panels on the engine mounting pylon, adjacent to the pneumatic latch panel, must first be removed.

b) At each pneumatic latch-mounted switch assembly, verify that the switch operating plunger is fully up. Insert a stop pin and push the stop pin fully home.

NOTE

The stop pin is retained by its handling loop abutting the access panel when the panel is closed.

a) At sub-panel DA-E open and collar circuit breaker C1 (LH system) and/or D1 (RH system).b) If both systems are to be inhibited, open and collar circuit breakers C4 and D4 (3A) and E1 (5A).c) Inspect visible mechanism for indications of damage.d) Check that blocker doors are correctly stowed and free of damage.e) Put a warning placard over the annunciators in the flight compartment reading, ‘THRUST REVERSER INOP’.
