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 40 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.
Proven PMA Expertise
Delivering uncompromising engineering standards since the first FAA approval in 1985 has led to improved component reliability and lower operational costs.
Advanced Design & Development
Our state-of-the-art Innovation Center addresses OEM limitations with shorter lead times, improved part availability, and often, product improvements.
Integrated Alternative Materials
Combining standard parts, PMA products, and DER repairs in a single assembly allows Wencor to provide the best option for our customers.
