EASA Grants Hartzell Engine Tech OK for Aircraft Alternator Upgrades

The European Union Aviation Safety Agency (EASA) grants Hartzell Engine Tech STC approval for Plane-Power ALT-FLX alternator upgrades in a wide range of piston-powered airplanes and helicopters. The upgrades were previously approved in the United States by the Federal Aviation Administration.

Aircraft covered by EASA's STC include a number of Aviat, Beechcraft, Cessna, Cirrus, Diamond, Extra, Mooney, Piper and SOCATA airplanes, as well as Robinson helicopters, among others.

“The Plane-Power ALT-FLX alternators are now STC-approved by EASA for a variety of aircraft and provide up to 100 amps in a 12-volt electrical system and up to 150 amps in a 24-volt system,” says Hartzell Engine Tech president, Keith Bagley. “Weights are comparable to replaced alternators, and kits provided contain all the brackets and hardware needed to complete the upgrade.”
