What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The PIC started the aircraft engine with a high throttle setting while on the ground facing an avionics business hanger. The engine started and the PIC lost control of the aircraft during a turn to the left. The right wing leading edge of the aircraft struck the tail section of a parked PA-30 removing the vertical fin and rudder sections of the aircraft. The left turn was wide enough to trace the tire tracks off the ramp leading to a grass area, then back to the ramp before stopping the aircraft. The PIC examined the damage to his aircraft and despite the advise of avionics technicians, departed the surgarland airport (ksgr) and returned the aircraft to a hangar at west Houston airport (kiws). The PIC flew the aircraft (N1988M) in an unairworthy condition after the accident. Further investigation showed several ad's had not been complied with on the last annual inspection.
