In the AS350 we had the rotor brake and fuel shut of lever located under the collective. It took a little bit of effort to cock your wrist so that you could reach these levers if/when needed. At the time our squirrels had an inefficient/ineffective gust lock. One of our trainees had a hot start, and attempted to activate the fuel shut off lever. His fore arm caught the collective as he was activating the fuel shut off and he became airborne. Unfortunately his flight only lasted a matter of seconds before he smite the ground.
I also understand that the PC9 had an accident with some confusion with respect to levers on the throttle quadrant. I QFI directed his pax (a none type endorsed pilot) to activate the gear/flap(?) lever. I believe the fuel shut of/emergency fuel (?) was/is located nearby and he shut the aircraft down – both ejected safely, but some embarrassment for the Kiwi exchange QFI.
