Probable cause

The pilot's exceedance of the airplane's critical angle-of-attack while maneuvering at low altitude, which resulted in an aerodynamic stall.

Findings · 2

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 was performing a low approach with full flaps about 30 feet above the runway. He further reported that when the airplane was about 60 feet from the end of the runway, he started to add power to go-around, but the airplane entered an aerodynamic stall. Subsequently, the nose of the airplane "suddenly" dropped, the airplane impacted the terrain, and stopped on the remaining runway surface. The fuselage and both wings sustained substantial damage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
