Hartzell Engine Tech received FAA Parts Manufacturer Approval for its Sky-Tec HT starters for Robinson two-place R22 and four-place R44 light utility helicopters. The company’s Sky-Tec HT starter for Lycoming engines features an integrated self-resetting Kickback Protection System (KPS) to protect the powerplant and starter from an engine kickback.
Hartzell Engine Tech President Keith Bagley, commented: “Hartzell Engine Tech’s durable Sky-Tec HT starters with their Kickback Protection System are in full production and available today through the company’s distribution system. They replace our older starters installed by Robinson helicopters at the factory and also older competitor starter units. The Sky-Tec brand, which we acquired in 2016, continues to reflect the highest levels of quality, innovation and value,” he added.
Robinson helicopter operators can check the Hartzell Engine Tech site at Product Lines Lycoming (skytec.aero) to determine if their specific model is covered under the new PMA. To find domestic and international distributors go to Distributors (skytec.aero).
Robinson Helicopter Company in Torrance, Calif. has produced more than 10,000 of the two helicopter models since the R22 was introduced in 1979 and most are still flying today. The PMA for these plug-and-play starters was obtained through the company’s Organization Designation Authorization program.
