NTSB Factual Report

The pilot reported that, during a hand propeller start, the tailwheel-equipped airplane was secured by having the passenger stand in front of the horizontal stabilizer. He added that, as he rotated the propeller with the throttle "cracked", the engine started, but "it ran fast enough" to break the passenger's hold. As the airplane began to move forward, he grabbed onto the lower right-wing strut in an attempt to enter the airplane. Subsequently, he let go, the left main landing gear ran over his shoulder, and the airplane stuck maintenance equipment.

The airplane sustained substantial damage to the right wing and fuselage.

During a telephone conversation with the NTSB investigator-in-charge, the pilot reported that, the throttle was "cracked a little more than it should have been." He added that, he did not use wheel chocks before attempting the start.

The pilot did not report that there were any preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to properly secure the airplane before a hand propeller start, which resulted in the airplane moving forward and colliding with maintenance equipment.
