In 10000 hours of helicopter time the biggest fright I’ve had is in one of those bloody things, descending right hand turn and it started the chugging thing, seriously thought it was going to destroy itself. Didn’t they start usiing stiffer transmission mount rubber blocks in an effort to fix that issue?
Is there any other aircraft built in mass numbers which have had so many tragic results from not totally explained reasons?
I will never get in another.
