The European Union Aviation Safety Agency (EASA) has granted Hartzell Engine Tech supplemental type certificate (STC) approval for Plane-Power ALT-FLX alternator upgrades in a wide variety of piston-powered airplanes and helicopters.
The STC was previously approved in the U.S. by the FAA.
According to Hartzell, the EASA STC covers a number of Aviat, Beechcraft, Cessna, Cirrus, Diamond, Extra, Mooney, Piper, and SOCATA airplanes along with several models of Robinson and Sikorsky helicopters.
The STC approved Plane-Power ALT-FLX alternators that “provide up to 100 amps in a 12-volt electrical system and up to 150 amps in a 24-volt system,” Keith Bagley, Hartzell Tech president, said in a statement. “Weights are comparable to replaced alternators, and kits provided contain all the brackets and hardware needed to complete the upgrade.”
