Probable cause
The pilot’s failure to maintain directional control during takeoff which resulted in a ground loop and collision with terrain.
NTSB analysis
The pilot of the tailwheel equipped airplane reported that, during takeoff from a field, the airplane veered to the left. While attempting to correct with right rudder control and brake application, the left main landing gear went into a rut and the airplane subsequently ground looped. The airplane sustained substantial damage to the right wing, right horizontal, and right elevator. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
