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.

APS also has FAA/PMA approval to manufacture on Silicon Rocker Cover Gaskets (direct replaement on Lycoming and Continental Brands) and Oil Drain-Back Tubes for Lyoming engines. For more information, check out their other products in the links below.
