Primary finding
Probable cause
The pilot's exceedance of the airplane's critical angle of attack while attempting to avoid a deer during landing, resulting in an aerodynamic stall.
Investigator assessment
Analysis narrative
The pilot reported that he conducted a visual approach to land at a grass airstrip with tall crops adjacent to the runway. As he was landing a deer jumped out of the crops onto the runway. The pilot pulled the nose up to avoid hitting the deer and the airplane stalled. The airplane hit the ground and "flipped" two times, substantially damaging the tail, wings, and fuselage. The pilot reported no mechanical anomalies with the airplane that would have precluded normal operation.
