Tension-Torsion Straps for Bell 206 Jet Ranger and 206L Long Ranger
Airwolf Aerospace developed a Tension-Torsion (TT) strap for Bell 206 Jet Ranger and 206L Long Ranger civilian and military helicopters. Airwolf manufactures the straps under an FAA PMA.
Airwolf’s TT straps anchor each rotor blade to the mast while accommodating the multi-directional forces inherent in rotorcraft flight. The straps are manufactured to better accommodate the torsion and tension requirements of the rotor hub.
TT straps must be replaced at 1,200 hours or two years, according to Bell Helicopter. They are approved for all Jet Rangers, Long Rangers and military OH 58s.
