Incident Overview
During a hand-propping start procedure, the engine of the aircraft unexpectedly accelerated to full power. The pilot managed to reach the controls as the aircraft began moving against its locked brakes. However, he was unable to arrest the forward motion before the aircraft struck a parked Beech 58P, registration N3664G.
Pilot Actions and Contributing Factors
The pilot reported that he had inadvertently left the throttle open while clearing the engine during the start sequence. Additionally, when attempting to reduce power after the engine had started, he forgot to press the button on the throttle control. The pilot noted that most of his flying experience had been in aircraft equipped with a different type of throttle mechanism.
Sequence of Events
The accident occurred during a ground operation involving hand propping, a method where the propeller is manually turned to start the engine. The exact location and date of the incident were not specified. The pilot's failure to ensure the throttle was closed and his unfamiliarity with the throttle button's operation contributed to the loss of control during the start.
Damage Assessment
The collision resulted in damage to both aircraft, though the extent was not detailed. No injuries were reported in the source.
