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.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
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.
