Aircraft involved
Probable cause & findings
The pilot's loss of directional control during the landing roll, which resulted in a runway excursion and an impact with terrain.
Factual narrative
The pilot of a tailwheel-equipped airplane reported that he encountered terrain induced turbulence over the runway threshold and bounced on the touchdown. During the landing roll, the left wing rose and the airplane began a "sweeping turn to the left." He attempted to correct with right rudder and brake, but the airplane exited the runway to the left, traveled about 25 feet down an embankment, and came to a stop. The right wing sustained substantial damage. The pilot stated there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
