ENGINEERING BETTER OPTIONS

For over 35 years, Wencor has been working closely with airlines and MRO’s to develop FAA Approved alternative parts for airframes and engines that offer increased availability, enhanced reliability and a lower total cost of ownership. With ~7,000 PMA’s we support most major aircraft and engines models across numerous ATA chapters.

Wencor has been delegated 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 ability to significantly reduce the time-to-market for PMA development projects.

Wencor’s in-house engineering addresses many of the pain points and limitations experienced with any OEM products.

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.
