FAA Parts Manufacturing Approval

Posted on March 28, 2019 James Williams FAA Parts Manufacturing Approval

Aviation parts are strictly regulated by the Federal Aviation Administration (FAA), whom are involved in all parts of manufacturing and distribution. Original Equipment Manufacturers (OEMs) or manufacturers with a Parts Manufacturing Approval (PMA) may produce aircraft parts.

After an OEM manufactures a part, the FAA uses an FAA approved method called Test & Analysis, or Test & Computations, to deconstruct the part and create their own production drawing to produce a PMA replacement part. The parts function, application, and criticality are studied, and the result will display the necessary dimensions, features, and characteristics of the part. PMAs can be considered a FAA manufacturing license that conveys the airworthiness of an aircraft part. 
The FAA emphasizes the importance of safety and instills safety standards to protect the lives carried aboard an aircraft. So, it’s not enough to just produce a part that mimics the original part, it must also meet FAA standards that shows its function and durability. A PMA part has a requirement to disclose to the FAA where the part will be used on the aircraft.
A, FAA airworthiness approval for a part can also come in the form of a Technical Standard Order (TSO). To obtain a TSO it is only required to follow minimum FAA mandated standards and requirements. In order to obtain an FAA PMA approval, the applicant must prove that their part is equal to or better than the original part.
Because parts are highly regulated by the FAA, it is safe to use parts other than the OEMs. However, it’s important to pay attention to the parts history and airworthiness to make sure it was produced according to the proper FAA standards. Parts should have appropriate documentation and labels that disclose this information.
