The PMA Advantage: Superior value & performance

WHY PMA?

A Parts Manufacturer Approval (PMA) is an FAA approved alternate part for use in the maintenance of type-certificated aircraft, engines, accessories and propellers. The FAA grants approval in the combined design, production, and installation authority, displayed in one document (the supplement).
As an industry leader with over 35 years of PMA design and development experience, Wencor provides PMAs to commercial, business and general aviation customers for virtually every section of the aircraft. Wencor also engineers Owner Operator Parts and Build to Print Machined Parts.

Wencor has been delegated authority by the FAA to perform Engineering, Manufacturing, Operations, Airworthiness, and Maintenance functions.

Wencor has been delegated authority by the FAA to perform Engineering, Manufacturing, Operations, Airworthiness, and Maintenance functions.

In 2009, Wencor was one of the first PMA companies to be awarded Organizational Design Authorization (ODA), which provides Wencor the unique opportunity to significantly reduce the time-to-market of PMA development projects.
