Probable cause
The student pilot’s failure to maintain yaw control during takeoff, which resulted in an aborted takeoff and subsequent landing on grassy terrain, during which the airplane bounced and then nosed over.
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 solo student pilot was flying in the traffic pattern and was intending to perform a touch-and-go landing. During the takeoff, the airplane "veered heavily to the left." The student attempted to correct the veer without success. The student then chose to land the airplane on grassy terrain. During the landing, the airplane bounced twice and nosed over, which resulted in substantial damage to the right wing and the rudder. The student reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
