Aircraft involved
Probable cause & findings
The pilot’s failure to maintain directional control during a full-stop landing, resulting in a runway excursion and impact with a snow berm.
Factual narrative
The pilot reported that while making a full-stop landing following a local flight in his tailwheel-equipped airplane and slowing on the runway centerline, the airplane began drifting to the left toward a snow berm on the edge of the runway. The pilot added power as the left main landing gear tire contacted the snow. The airplane slid into the berm and came to rest in about 8-12 inches of snow. The airplane sustained substantial damage to the left elevator. The pilot reported there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
