Bell 206 Question


Recommended Posts

This came across my desk a few days ago;


"The K-Flex coupling on the power shaft came into contact with the transmission isolation mount..."


Any ideas what may have caused this? It wasn''t improper installation and I know it was bad enough that the coupling had to be replaced.

Wario: Some reasons for past contacts I have seen with D/S and isolation mount include;


1. Soft mount/rubber

2. Landing/taking off on a slope or angled suface incuding floating barge/ship where there is considerable movement of the deck.

3. Incurrence of negative G in flight (rare one)
