Aircraft Accident/Incident Report

Livermore, California 94550
Thursday, March 21, 2013 15:10 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that after a normal landing, the tailwheel-equipped airplane began to drift right and that he applied control inputs to counteract the drift. The airplane then started to veer to the left, and the pilot applied right rudder to stop that movement; however, his foot became entangled in the rudder pedal, and the airplane ground looped. Subsequently, the right main landing gear collapsed, which resulted in substantial damage to the fuselage. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control during the landing roll.
