The Superior Air Parts

PMA story

How we make our PMA parts as good as the “original” parts


As one of the largest PMA producers in the industry, one question we get asked a lot is: how we go about creating our FAA-Parts Manufacturer Approval (PMA) parts? Well, it’s a long process. The first step is determing why our customers need these parts in the first place?

The two biggest reasons are price and availability. OEM parts are becoming hard to get or they are becoming much too expensive.

Once the part is identified, we do a thorough design and metallurgical analysis. We also gather information from engine shops to find out if there are any opportunities to improve on the performance.

Of course the part’s form and function must match or exceed the original's standards in order to receive our PMA from the FAA. With that as a foundation, our engineering team creates a new design for the part that takes advantage of any new advancements in materials or manufacturing.

Once the design is finalized, we then work with the best manufacturing facilities around the world to craft each part using the most advanced materials and production techniques available. The result is that our FAA-PMA parts often set new standards for the aviation industry.
