PMA Twin Otter Parts List & Beyond!


PMA Parts List by Specific Aircraft Applications (PDF):


PMA Design and Manufacturing’s primary objective is to engineer and manufacture FAA approved PMA parts that meet or exceed the original equipment manufacturer’s (OEM) item specifications, often at a substantial savings compared to the OEM prices. We supply PMA's to most major airlines with Twin Otters and to the manufacture of the latest series of the Twin Otter.


Team JAS’ quality control ensures that your PMA components are of the highest quality and are fully interchangeable with their OEM equivalents. JAS-PMA parts are engineered, manufactured and inspected according to Federal Aviation Regulations Part 21. Our on-staff DMIR’s are available to provide same-day 8130 approvals.


Our goals are to deliver high quality aircraft parts, to maintain an active inventory of our FAA approved PMA parts, and to meet our customers need for just-in-time deliveries. We engineer and manufacture those “hard to find” consumable parts that aircraft owners and operators use on a daily basis.

Continued Growth

Team JAS' manufacturing division is part of MARPA. MARPA is the non-profit trade association that represents the Parts Manufacturer Approval (PMA) community. On a daily basis we reminder ourselves that we're here to do the following for our customers: Deliver High Quality Parts, Maintain Active Inventory, Meet Customers Needs.

Educational Material

“Lack of knowledge about PMA continues to be a major obstacle in the path to achieving PMA savings. In the view of the FAA there is no drop off in status from the OEM part to the PMA part. Both have equal standing.”
