WARNING
BACKGROUND. Replacement parts, materials and accessories may be sold as being of aircraft
quality when actually the quality and origin of these units are unknown. Users of such units are
usually unaware of potential hazards involved with replacement parts not eligible for use on
certificated aircraft. Units may be deceptively advertised as "unused," "like new" or
"remanufactured." This implies the quality of such units is equal to an original, repaired or
overhauled unit.
Federal Aviation Regulations (FAR) 43.13 and FAR 145.57 specify performance rules for
replacement of parts and materials used in maintenance and alteration of United States (US)
certificated aircraft. As outlined in FAR 91.403, FAR 121.363, FAR 123.45, and FAR 135.143 (a),
the
owner/operator is responsible for continued airworthiness of the aircraft which includes parts
replacement.
IDENTIFICATION OF THE APPROVED PARTS. Approved serviceable replacement parts are
identified by:
a. A Federal Aviation Administration (FAA) Form 8130-3 Airworthiness Approval Tag. An
Airworthiness Approval Tag identifies a part or group of parts approved by authorized FAA
representatives.
b. An FAA Technical Standard Order (TSO) number and identification mark that indicates the
part or appliance has been manufactured under the requirements of FAR 21 Subpart O.
c. An FAA Parts Manufacturer Approval (PMA) symbol, together with the manufacturer's name,
part number and make and model of the type certified product on which the part might be
installed, stamped on the part. An FAA / PMA is issued under FAR 21.305. The make and
model information may be on a tag attached to the part.
d. Shipping ticket, invoice or other document which verifies the part was manufactured by a
facility holding an FAA Approved Production Inspection System issued under FAR 21 Subpart
F or by a manufacturer holding an FAA Production Certificate issued under FAR 21 Subpart G.
e. Certificate of airworthiness for export issued by a foreign government under the provisions of
FAR 21 Subpart N.
KNOW YOUR SUPPLIER. Many reproduced parts and components are available for purchase
and installation on US certified aircraft. Often, an original part is used as a sample to produce
duplicates. The reproduced parts appear to be as good as the original part; however, many
unknown factors are not readily apparent to the purchaser such as degree of heat treating, plating,
inspections, tests and calibrations. Often the faulty part is not discovered until a malfunction or an
accident occurs.
SUMMARY. In accordance with FAR certification of materials, parts and appliances for
return to service for use on aircraft is the responsibility of the person\agency who signs the
approval.
The owner/operator is responsible for the continued airworthiness of the aircraft. To
assure continued safety in aircraft operation, great care must be used when inspecting, testing
and determining the acceptability of all parts and materials. Exercise extreme discretion to identify
and establish the origin of materials, parts, and accessories.
