Every company which manufactures
parts not integrated into the
aircraft at the time of "Type
Certification" must obtain their
own Parts Manufacturer Approval
(PMA) from the Federal Aviation
Administration (FAA). The FAA
has been granting PMA since the
late 1960's. |
| |
There are four (4) methods by
which PMA's are approved by the
FAA:
-
License
-
Test and Computation
-
Identicality
-
Supplemental Type Certificate
(STC)
|
| |
"PMA by License" means that the
Type Certification Holder
(Boeing, Airbus, Pratt, GE etc.)
grants a "license" or right to
produce parts with its approval
and technical support and the
FAA follows with its
manufacturing authorization.
Whereas in each of the other
three cases the parts
manufacturer must create a
different part number. When a
PMA is granted through a
"license" the part number
remains the same as that of the
Type Certificate Holder. For
example, the Boeing part is
63-12345-6, under a PMA by
license, Boeing would grant the
license and the FAA would
approve the part manufacturer to
make the part and sell it with
the part number 63-12345-6,
which is the identical part
number.
In
the other methods of PMA's
listed above, the part number
must use either a prefix
(D69-12345-6), suffix
(69-12345-6D) or entirely
different part number, because
the part number has not been
approved by the Type
Certification Holder (TCH) as a
licensed part number.
|
| |
When a manufacturer receives
authority from the FAA to
manufacture a PMA part, the FAA
issues a "PMA Supplement" to
document the approval and the
method of approval. This
supplement for a licensed PMA
will document that the approved
PMA part number and the original
TCH part number are identical.

OEM Licensed PMA's offer
significant cost savings vs. OEM
products. In addition, ancillary
cost savings include reduced
engineering workload and part
commonality saves inventory
control costs.
