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 reported that, while rolling out on landing, the airplane suddenly veered to the right causing the nose to turn to the left. The student pilot attempted to correct with opposite rudder; however, the airplane exited the left side of the runway, proceeded down a terrace, and nosed over, which resulted in substantial damage to the vertical stabilizer. The student pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. At the time of the accident, the student pilot was landing the airplane on runway 34 with wind from 300° at 6 knots.
