PMA

Why PMA?

A Parts Manufacturer Approval (PMA) is an FAA approved alternate replacement part for use in the maintenance of type-certificated aircraft, engines, accessories and propellers. The approval confers combined design, production, and installation authority in one document (the supplement).

As an industry leader with over 30 years of PMA 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.

Our FAA-approved components typically offer 40-60% cost savings over the OEM equivalent.

  • Wencor’s engineering expertise can also incorporate significant improvements, resulting in more reliable aircraft components.

The FAA has delegated Wencor the authority to perform engineering, manufacturing, operations, airworthiness and maintenance functions.

  • Wencor was one of the first PMA companies to be awarded Organizational Design Authorization (ODA) in 2009. This means Wencor can significantly reduce the time to market of your PMA development projects.

Our design and engineering processes address many of the pain points and limitations of OEM products.
