Probable cause
The student pilot’s failure to maintain airplane control during the landing roll and the flight instructor’s delayed remedial action, which resulted in a ground loop.
Findings · 5
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 student pilot of the tailwheel-equipped airplane reported that, during the landing roll after the initial touch down, the airplane veered to the right. He applied excessive left rudder input to correct it, causing the airplane to oscillate left and right. The flight instructor attempted to regain the directional control, but his foot became caught. As the airplane decelerated and the oscillation increased, the airplane ground looped to the left, resulting in substantial damage to the right wing and aileron. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
