What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) PIC attempted to hand prop the engine. Another person assisted by holding on to the rail. Pilot stated a gust of wind startled the person holding the tail of the aircraft, and he let go. The aircraft then moved under its own power and struck a building. Person holding the tail of the aircraft stated that the throttle was open too FAR causing the aircraft to move uncontrollably, and thus he was unable to hold the aircraft.
