Cyclic bumping
Gator,
Yes, I strongly suspect that many of the mast bumping incidents in Robinson are related to the cyclic being knocked out of the pilots hands by a passenger knocking the centre post.
It's only happened to me once, by a friends wife sat beside me trying to point a scenery... we were in the mountains on a beautiful sunny evening, so you can imagine how the accident report would have read...
Despite the common doctrine for a two finger grip for fine control movements these days the cyclic gets a somewhat firmer grip from me.
