Design, Standards and Quality Assurance
Why Quality in Service?
Understand and improve operational processes.Identify problems
quickly and systematically.
Establish valid and reliable
service performance measures.
Measure customer
satisfaction and other
performance outcomes.
Use quality practices to:
Aviation Quality Assurance Aviation quality assurance is a
system for monitoring aviation equipment, programs, and procedures to ensure that the Federal Aviation Administration (FAA) quality standards are being met.
The Aviation System Standards (AVN) was designed to maximize the effectiveness and safety of aviation operations, and is enforced by the FAA Safety and Quality Assurance Office.
The primary safety programs of the Aviation System Standards include:
Flight Safety Environmental Occupational Safety and Health Safety Management Systems Internal Evaluation Programs
The Flight Safety program is a leading example of a quality assurance system in action. Safety programs are developed and tested to assess potential risk factors in flight operations.
Two key programs that monitor and resolve flight safety issues are:
the FOQA (Flight Operational Quality Assurance)
the ASAP (Aviation Safety Action Program)
Both programs collect and analyze recorded flight data. The information is taken from routine flights or is collected in response to an accident; either way, it is used to assess the safety of flight operations, air traffic control methods, and airport and aircraft design and maintenance.
Repair stations and aircraft maintenance technicians are subject to quality standards regarding their inspections, maintenance, and repair work. They can also use the information obtained through FOQA and ASAP programs to improve maintenance procedures.
The quality assurance standards ensure that aircraft are kept in optimal working condition, and are safe for private and commercial use.
Maintenance Of Aircraft Maintenance of aircraft is a comprehensive,
ongoing process. The entire aircraft needs to be examined, maintained, and have the necessary parts replaced to uphold the safety standards mandated by the FAA.
Aircraft are required to be maintained after a certain period of calendar time or flight hours or flight cycles.
Proper aircraft maintenance is essential for keeping aircraft and aircraft parts in optimal condition, and ensuring the safety of pilots, crew, and passengers.
Proper inspection methods must be employed to insure that the aircraft can be certified airworthy
FAA Aircraft Certification
The FAA aircraft certification
process is not rocket science...
….but there are certain steps that must be followed and key information, should know to avoid the problems that can occur.
STANDARD PARTS A standard part is a part or
material that conforms to an established industry or U.S. Government-published specification. The FAA’s acceptance of a standard part as an approved part is based on the certification that the part has been designed and produced in accordance with an independent established set of specifications and criteria.
Standard parts are produced per published specifications and criteria.
To provide approvals under which parts could be produced, the FAA issued the following Technical Standard Orders (TSO): TSO-C148, Aircraft Fasteners; TSO-C149, Aircraft Bearings; and TSO-C150, Aircraft Seals. Authorizations for these TSO’s are not issued for standard parts nor for parts used in critical applications. In contrast to “standard part” nuts, bolts, etc., these fasteners, bearings, and seals must meet the TSO minimum performance, marking, and installation approval requirements.
Aircraft quality assurance inspector has to insure that all of the maintenance that has been done on an aircraft meets the technical standards that have been established by the aircraft manufacturer and the Federal Aviation Administration. Aircraft maintenance that is done incorrectly can cost human lives. Quality assurance inspectors are responsible to objectively enforce proper aircraft maintenance procedures.
Aircraft tires are classified by size, structure, ply rating as well as by inflation pressure and tire profile.
Bridgestone (leading tires manufacturing company) currently manufactures Type III, VII, Radial, Metric and Three Part Type tires.
Rib Deflector Tread This pattern (CD, RD) was developed for rear-
engined jet aircraft. A flange is provided on the sidewall to deflect runway water away from the engines.
