Probable cause

The pilot's exceedance of the airplane's critical angle of attack during a go-around, which resulted in an aerodynamic stall and subsequent impact with terrain.

Findings · 4

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 had just landed when he thought that he saw a crop duster airplane descending for a short base for landing on the opposite runway. The pilot initiated a go around with the flaps still extended and with a high-density altitude. The airplane attained an altitude of about 50 to 100 ft above ground level when the airplane stalled, and the left wing dropped. The pilot attempted to recover but did not have enough altitude before the airplane collided with the ground. The airplane nosed over and came to rest inverted. The wings and fuselage were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
