Incident Overview
According to the pilot, no tiedowns, chocks, or other restraining devices were available before the start of the engine. To compensate, the pilot instructed a non-certificated person to sit in the aircraft and apply the brakes while he rotated the propeller by hand to start the engine.
Sequence of Events
The engine started successfully. However, the individual in the cockpit inadvertently increased engine power. The pilot was unable to stop the aircraft, which then rolled forward and collided with three other parked aircraft. Subsequently, the aircraft struck a dirt bank, causing the nose gear to collapse.
Findings
The investigation did not specify any injuries, aircraft types, registrations, or further details regarding the pilot or the non-certificated person. The event was attributed to the lack of proper restraining devices and the inadvertent power increase by the non-certificated person.
