Australia’s Airwork Helicopters has received an FAA supplemental type certificate (STC) for composite tail rotor blades for the Bell Helicopter B206, the company said.
The certificate is dated some 22 months after the company said it received Australian certification for the same product. In May 2015, Airwork Helicopters received Civil Aviation Safety Authority STC and Australian Parts Manufacturing Approval for manufacturing the blades.
Airwork Helicopters said its 206 composite tail rotor blades have a 5,000-hour life, significant noise reduction, 30% lower hourly operating cost, increased strength, replaceable bushings and abrasion strips, corrosion resistance, are impervious to salt water and have improved ground clearance.
