Primary finding
Probable cause
The pilot’s failure to maintain directional control of the airplane during the takeoff roll.
Investigator assessment
Analysis narrative
The pilot of the tailwheel-equipped airplane reported that, during the takeoff roll, the airplane started to veer left. As he recovered, the airplane "violently" turned to the right and exited the runway. He reduced the engine power, and the airplane nosed over. The airplane sustained substantial damage to the left-wing lift strut and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
