Duncan Aviation has created an online parts manufacturer approval (PMA) library comprising more than 75 PMAs that are available for sale, the Lincoln, Nebraska-based MRO provider announced. PMAs in the searchable library can be found by aircraft, PMA category (such as Aircell, airframe, installations, and interiors), or viewing the full list.

The PMA library is in addition to Duncan’s searchable online library of STCs produced by its engineering and certification departments. Those can be sold as a complete STC package or as individual PMA parts. “You can think of a PMA as an egg that’s a part of an entire carton; the STC is the entire carton, with regard to STCs,” Duncan Aviation PMA project lead Chad Ladwig said. “We can sell the entire carton, the STC, or we can sell the individual eggs, the PMA.”

Since going live with the PMA library, Duncan said it has received multiple requests for quotes, including dust panes for Cessna Citation 550s and 560s and Gogo kits modification parts for a Wi-Fi system.
