Accident Sequence
According to the pilot, during an attempted engine start, the battery was found to be low. The pilot exited the airplane and instructed the passenger to remain inside, explaining how to turn the magnetos on and off. Subsequently, the pilot used the tail tie-down hook and secured the tail of the aircraft to the ramp with a rope. The pilot then hand-propped the engine, which started, but the throttle was positioned too far forward, causing the airplane to accelerate. The rope, described as old, broke under the strain. The aircraft continued forward, and the passenger turned the magnetos to the OFF position. Despite this action, the airplane continued and impacted a hangar before coming to rest.
Aircraft Damage
The accident sequence resulted in substantial damage to the firewall and right wing of the airplane. No further specifics about the extent of damage were provided.
Pilot Report
The pilot reported that, aside from the low battery, there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
