FREQUENTLY ASKED QUESTIONS
United States
Parts documentation
for U.S. repair stations
The following is from Federal Aviation
Administration regulations and advisory circulars.
Question: What documentation is
required for parts?
Answer: There are three answers to this
question: First, the regulatory answer from a U.S.based
Part 145 repair station (and independent
Part 65 maintenance organizations); second, a
foreign-based FAA Part 145 covered under a
Bilateral Aviation Safety Agreement; and third,
what your customers contractually require of you.
Most Bilateral Aviation Safety Agreements
evaluate the existing regulatory system in the
host country. In many cases, the traceability for
parts of the host country may exceed the broad
approach allowed by the FAA. As such, a foreignbased
FAA Part 145 repair station must follow
whatever guidance is provided in the Bilateral
Aviation Safety Agreement.
In many cases, your customer may have a
more-limited acceptance of traceability of parts
than the broad application of the regulations, in
which case, you should meet your contractual
obligations.
However, for a U.S.-based Part 145 repair
station and independent Part 65 maintenance
organizations, the best guidance is contained
within FAA Advisory Circular 20-154: Guide for
Developing a Receiving Inspection System for
Aircraft Parts and Materials.
Contained within paragraph 6: Developing the
Receiving Inspection System Plan, paragraph
h, Part/Material Documentation/Identification,
states:
Procedures should clearly state and/or
illustrate the documentation or other means
of identification that would be acceptable
for receiving parts or material from different
types of vendors. The following are possible
sources, but not the only sources, for
determining airworthiness:
1. Shipping ticket, invoice, or other
documents from the PAH.
2. Parts markings such as PMA, TSO,
data plates, serial numbers, part
numbers, manufacturing production
numbers, etc.
3. Letter of Direct Ship Authority,
issued to the supplier by the PAH.
4. Maintenance release document(s)
that meet Part 43, signed by
an appropriately certificated
person, qualified for the relevant
function, that signifies the item
was approved for return to service
after maintenance, preventative
maintenance, rebuilding, or
alteration. Records could also reflect
the removal of parts/components or
appliances from a TC'd product.
(5) FAA Form 8130-3 is used for export
approval, conformity determination from the
PAH, or approval for return to service after
maintenance or alteration by an authorized
Part 145 repair station or the holder of
an air carrier operating certificate issued
under Part 121 or 135. Export Certificate
of Airworthiness, JAA Form 1 (invalid if
dated after 11/28/04), Transport Canada
Authorized Release Certificate - Form One,
and EASA Form 1 (effective on 11/28/04)
provided the United States has a current
BASA and MIP with the exporting country.
Part or material certification forms such as
ATA Form 106, or a material certification
form verifying that the standard parts
conform to established industry or U.S.
specifications, could be provided. q
