What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) "Industrial incident-no intent to fly". On September 11, 2002 at 1324 PDT a Robinson R-22 became airborne with a a & p certificated mechanic as the sole occupant in the aircraft. Since he did not knot how to fly helicopters and it was only about 4-5 feet above the ground when he elected to exit the aircraft out of the right side door while the aircraft was still in flight causing the aircraft to go out of control and strike the ground. Substantial damage occurred to the aircraft after it came to rest in the dirt next to the taxiway where it had been parked. While performing a maintenance engine runup to tighten the belts the mechanic had just completed a full power runway and reportedly had taken his hand off the throttle (on the collective) however the governor was still in the "on" position and resulted in full power being applied to the engine with the collective not frictioned to the down position. The aircraft became airborne and the result is as staed in the preceding paragraph. VFR conditions prevailed. The mechanic had abrasions on his head and wrist and back but no other person was injured.
