Primary finding
Probable cause
The pilot's failure to maintain directional control during the landing roll, which resulted in a runway excursion and damage to the left aileron and elevator.
Investigator assessment
Analysis narrative
The pilot of the tailwheel equipped airplane reported that during the landing roll he lost directional control, which resulted in a ground loop to the left, a runway excursion, both main landing gear collapse, and substantial damage to the airplane's left aileron and elevator. The pilot reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
