Bell 206 Question

Wario · July 13, 2003

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.

How hard?

The only time I have ever seen that was after a hard landing.

Have a talk with the last person to drive it.

An extreme off level landing could also have caused this,tail low I would think....as mentioned check with the last driver...oops!

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)
