Oldlae is on the money.
JUANK
The dreaded "collective bounce". I have taken 2 aircraft straight to maintenance because of low minimum collective friction.
Afterwards when other pilots return to fly the aircraft the "whining" about the collective friction is louder than the engines.
The "chorizo's" in the pilot seat are too SOFT!
It is not "optional" - get used to it.
This issue is not limited to Bell medium products, it affects the Super Puma as well.
It has destroyed a few aircraft - if all else fails RTFM!!!!!!!!!!!!!!
