Primary finding
Probable cause
The pilot's failure to maintain directional control during the landing roll, which resulted in a runway excursion and encounter with terrain.
Investigator assessment
Analysis narrative
The pilot reported that the airplane landed on centerline, immediately pulled to the left, and quickly left the runway. It continued until encountering a swampy area at which time the nose wheel dug in, and the airplane nosed over. The left wing strut and wing sustained substantial damage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
