Probable cause

The pilot's failure to maintain yaw control and his exceedance of the airplane’s critical angle of attack during an aborted landing, 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 of the tailwheel-equipped airplane reported that, during landing, as soon as the main landing gear touched down, the airplane yawed left. He tried to correct with right rudder and applied full power for a go-around. During the go-around, the airplane seemed to continue to yaw left, and he attempted to correct with full right rudder, but the airplane continued to drift left, aerodynamically stalled, and subsequently collided with the ground. The airplane sustained substantial damage to the wings, fuselage, and empennage. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation.
