Location: Geneseo, NY
Accident Number: GAA17CA560
Date & Time: 09/27/2017, 1245 EDT
Registration: N38633

Defining Event: Loss of control on ground
Injuries: 2 Minor
Flight Conducted Under: Part 91: General Aviation - Personal

Analysis 

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 National Transportation Safety Board 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 reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
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.
