NTSB Factual Report

The pilot reported that during the takeoff roll in a tailwheel equipped airplane, he inadvertently actuated the left brake when his left foot became entangled within the rudder pedal and control cable. The pilot stated that he then lost control of the airplane and subsequently groundlooped, which resulted in structural damage to the fuselage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to maintain directional control of the airplane during takeoff roll.
