It was touched on a little bit when I was at the factory school last year. The straps between the OH-58 and the JetRanger are identical, the only difference is in the paperwork. It was mentioned that only one time have they had a TT failure, and I think it was in an OH-58. IIRC, there was a small hole in the epoxy coating, allowing moisture into the strap which then corroded the wire inside.
I'm sure they don't mind the extra revenue from all those straps, and they can reduce their liability by making them get replaced all the time.
