THE APS Brake DIFFERENCEFAA-PMA certified Brakes

APS brake discs and linings have successfully completed a rigorous design and testing process in order to receive FAA-PMA certification.  The approval process often takes months or even years to complete since the FAA requires that all PMA parts meet or exceed the standards of the OEM factory part that they are replacing.  APS discs and linings are FAA approved direct replacements for the OEM brakes & linings under this PMA approval.   


Single Piece ForgingHigh Grade Aerospace Steel

Each disc is manufactured from a single piece, premium quality carbon steel forging. When the metal is forged it creates a directional grain flow that follows the contour of the disc which reduces the risk of cracks and catastrophic failure associated with the inferior welded design.

The Highest Technical Standards

APS uses the highest technical standards available in its manufacturing processes, producing a disc with extremely precise tolerances. This ensures correct run-out values which eliminate disc vibrations and ensures improved pad to disc fit for better braking and performance. APS brakes have been tested by demanding dynamometer testing as well as extreme flight testing.


Our state-of-the-art CNC lathes ProvideExtremely tight tolerances

APS has the capability to maintain extremely tight tolerances with state-of-the-art CNC lathes. When coupled with a well-researched design and extreme testing, the result is a longer-lasting disc with higher performance and greater safety margins.

After machining, the discs are subjected to a proprietary heat treatment process that gives the discs their characteristic appearance. APS brakes are not only aesthetically pleasing but offer enhanced wear characteristics and have a high resistance to corrosion and longer life associated with the thermal cycling experienced in the aircraft braking environment.

The corrosion protection also makes the discs particularly suited for agricultural aircraft that are exposed to harsh chemicals as well as aircraft located in coastal areas and aircraft that are left outside on the ramp full time.

A good many of our staff at APS are pilots and we know how important it is to you to trust your braking equipment.  In a highly regulated and safety-conscious industry such as aviation, APS goes beyond FAA and industry requirements to ensure that you can brake with confidence.
