Aircraft involved
Probable cause & findings
The pilot's failure to maintain directional control during the landing roll with a light crosswind, which resulted in a runway excursion and collision with terrain.
Factual narrative
The pilot of the tailwheel-equipped airplane reported that, he was landing with a light crosswind from the left. The main landing gear touched down followed by the tailwheel and the pilot began applying the brakes while maintaining back pressure on the control stick. As the pilot increased brake pressure, the airplane veered to the left. The pilot increased power and added right rudder control, however, the airplane exited the runway. The right main landing gear collapsed, and the right wing was substantially damaged when it struck the ground. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
