Aircraft Aircraft Damaged
Human Factors
Hand-propped aircraft was started with throttle fully advanced; and no one in cockpit. Traveled approximately 10-15 FT collided with a parked truck. The right wing also contacted the tip of the vertical stabilizer on a nearby aircraft. Damage: Truck -- Side of body received impact damage; tire punctured by prop tip; flat 'topper' punctured by prop tip. Other aircraft -- broken vertical stab attach bracket; dented tip on vertical stab. Accident aircraft -- bent prop; bent motor mount; dented cowl; 1 bent wing rib.Details: I was being instructed on how to prop this airplane. First attempt resulted in flooded carburetor. Per procedure; magnetos were shut off; throttle advanced to full; and prop turned backwards 8 blades. Then magnetos on; throttle retarded to idle; except that after magnetos on and just about to retard throttle; another vehicle appeared and was insistent that he would drive around the plane. There was insufficient room; so trotted off to turn him around and forgot that the throttle was still advanced. Plane jumped chocks; we were able to pull throttle back; but it was still moving and spinning down to idle when it hit truck.
Luscombe 8A pilot reported the aircraft got away from him during a hand prop exercise with an instructor; striking a truck and another aircraft.
