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.

According to Airwolf senior engineer John Montana, “The development of Airwolf’s new torsion-tension straps is the result of more than seven years of research and development.” He said the new product is “technically superior.” The straps can be installed in the field by a licensed mechanic or repair station.

Montana described the price as “significantly lower” than that of the original Bell parts. “For years the only option was no option at all,” he said. “Now, there’s a much more affordable and FAA-approved alternative.”

Exact pricing and information regarding use and installation is available at the Airwolf booth. The Middlefield, Ohio manufacturer expects to begin shipping its TT straps in April.
