Aerometals Earns PMA For MD500 Transmission Gears

FAA has granted parts manufacturer approval (PMA) to El Dorado Hills, Calif.-based Aerometals for the main rotor transmission on the MD500. The PMA comes after Aerometals built a test stand with a 500-hp electric motor instead of a gas turbine. The MD500’s transmission, rated at 425 hp for up to five minutes, ran at 467 hp for eight hours during the Aerometals PMA testing process with FAA.
