FAA OKs Duncan Aviation’s PMA Quality System
The company can manufacture approved parts to support its own STCs as well as many OEM installations.

Duncan Aviation completed an FAA quality system audit of its PMA approval quality system. The PMA authorization allows the company to manufacture approved replacement parts to support its own STCs and many OEM installations. The audit, performed every three to four years, verifies that Duncan consistently produces high-quality parts to FAA-approved design data, while maintaining compliance with the applicable FAA regulations. Additionally, the FAA found that Duncan maintains the proper records, ensuring that every part manufactured at its Lincoln, Neb. facility can be traced from its raw material state to the finished product.
