b. If STC-approved interior kit with
either PMA or TSO-approved materials for a
part 23 aircraft is bought, the mechanic would
only have to reference the STC number on
FAA Form 337 and the aircraft’s records.
Part 23, appendix F would not be required.
c. If an annual inspection is to be
performed on a part 23 aircraft in which a
new interior was installed, but the aircraft’s
records do not reflect that a burn test was
performed on the interior’s materials and
fabric by an FAA Approved Repair Station, or
there is no mention of an STC or FAA
Form 337 in the aircraft records, then a burn
test that meets, part 23, appendix F must be
accomplished before the aircraft is approved
for return to service.
9-63. SOURCE OF INFORMATION. If
information regarding the original or properly
altered fire protection qualities of certain cabin
interior materials is not available, requests for
this information should be made to the aircraft
manufacturer or the local FAA regional office,
specifying the model aircraft and the aircraft
manufacturer. The date the aircraft was
manufactured or the serial number, and the
14 CFR part under which the aircraft is
operated (i.e., CAR-3, 14 CFR part 91, or
part 121, etc.).
9-64. UPHOLSTERY AND/OR BELTS.
Upholstery and/or belts that have been washed
may lose some or all of their fire-resistant
qualities. Unless the soap is completely
removed from the cloth, the strength of the
material may be significantly reduced. Consult
the manufacturer to determine how to maintain
the fire-resistant qualities.
