Probable cause

The pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle of attack during the landing flare, which resulted 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 receiving instruction reported that, during an airplane checkout, he performed a simulated engine failure. He added that, during the landing flare, the airplane "ran out of energy," and the right wing struck the runway. The flight instructor reported that, about 5 ft above the runway, the airplane aerodynamically stalled, and the right wing dropped and struck the runway. The airplane sustained substantial damage to the right wing. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
