4. 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.

5. The primary safety programs of the
Aviation System Standards include:
 Flight Safety
 Environmental
 Occupational Safety and Health
 Safety Management Systems
 Internal Evaluation Programs

6.  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

7.  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.

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

10. 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

11.  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

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.
 CD: Center rib with deflector
 RD: Center groove with deflector
