OPP

"OPP" stands for Owner Produced Parts

Aero-Vintage Consulting does not sell new parts for TC approved aircraft.  Instead, AVC supports the OPP process.  We have developed streamlined procedures to assist airplane owners to properly execute the "Owner Produced Product" rule, reference 14 CFR 21.303(b)(2). 

Here are some of the parts produced by our customers with assistance from AVC.

OPP - Regulatory Issues - To sell a new aircraft "part" to be installed on a Type Certificated aircraft, that part must be FAA PMA'd (have FAA parts manufacturing approval), reference 14 CFR 65.303A. Obviously this is impossible on most older aircraft because it is a big deal to obtain PMA. The alternative is to allow the owner/operator to produce this part and then install it on his Type Certificated aircraft. The owner may contract to have that part produced but he must be actively involved in the production of that part by providing input or assistance to the producer of the part. He could provide drawings or the original part. He could participate directly in the production of the part by personally supervising the manufactering of the part or provide quality control. The data used would have to be "approved data." The airplane owner/operator would make a log book entry that identifies the owner produced part [FAR 21.303(b)(2)], specifying his participation in the manufacturing of the part, and make a declaration that the part is airworthy. This policy is defined in FAA AGC-200 policy memorandum on the definition of an "owner produced part" dated Aug. 5, 1993.
