Eric Wolff is pleased with his company Airwolf’s timeline for delivering on its promise of aftermarket life-limited PMA parts for Bell 204, 205, 212, UH-1 and Enstrom 480 helicopters by the end of the summer. But Airwolf (Booth No. 3513) had a bit more news at this year’s Heli-Expo. According to Wolff, the company will be the OEM supplier of TT straps for the Enstrom 480 by year-end, as well.
Airwolf Filter Corp., a specialist in remote-mounted oil filter systems for piston aero engines, has scored a first. Over the past year, a team from the Middlefield, Ohio-based company has identified has identified every aircraft data sheet on file with the FAA and EASA and added to their approval model list every remaining piston-engine aircraft powered by a Continental, Curtiss-Wright, Franklin, Husoi, Jacobs, Kinner, Lycoming, Ranger, Warner or WSK PZL Kalisz engine.
After spending last year traveling the globe with world-renowned aviators, Breitling’s first (of 500) Naval Centennial Limited Edition Airwolf timepiece is being auctioned online to benefit the National Flight Academy. The auction will close at 5 p.m. EST on February 29. The first-off-the-line watch was worn by aviators in a global journey that started with Commander Mark Kelly on Space Shuttle Endeavour’s last flight into space in May.
Airwolf Aerospace of Middlefield, Ohio (Booth No.10243) announced it has received FAA Supplemental Type Certificate (STC) approval for its recently PMA-approved Torsion-Tension-(TT) Straps for Bell 206 JetRanger, 206L LongRanger and OH 58 helicopters, as well as STCs from the European Aviation Safety Association (EASA), Brazil’s Agencia Nacional de Aviacao Civil (ANAC) and Transport Canada.
These STCs will allow installation of the straps in regions of the world that do not otherwise permit use of PMA parts for flight critical components.
Airwolf Aerospace has developed a new tension-torsion (TT) strap for Bell 206 JetRanger and 206L LongRanger helicopters and military variants, including the OH-58 Kiowa. The straps, manufactured under FAA parts manufacturer approval (PMA) regulations are on display here at the Airwolf booth (No. 3561).
The TT straps anchor each rotor blade to the mast while accommodating the multi-directional forces inherent in rotorcraft flight.
For Robinson Helicopter, switching from aluminum to stainless-steel skin for main rotor blades has been “a mixed bag,” said company vice president Kurt Robinson, who defended the move on the grounds that the change means lighter and stronger blades with better corrosion resistance. But critics argue that the stainless skins do not hold paint well and that the switch from aluminum
The European Aviation Safety Agency has granted approval of a recent FAA-approved rotor blade tape installation STC for Robinson R22s and R44s. Airworthiness Directive 2007-26-12 was issued to address delamination of the helicopters’ main rotor blades.
Airwolf Aerospace has been issued an FAA STC for its permanent fix for main rotor blade delamination on the Robinson R22 and R44, an issue covered by Airworthiness Directive 2007-26-12. According to the AD, the blade skins begin to debond at the skin-to-spar bond line near the blade tip, and can separate when the bond line is exposed due to excessive erosion of the blade finish or when corrosion occurs on the internal aluminum tip cap.
Airwolf Aerospace, a provider of firewall-forward accessories, has been awarded an FAA STC that the company claims will permanently prevent leading-edge skin delamination on Robinson R22 and R44 helicopter main rotor blades.
