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 was on his first solo flight and was attempting to land. Just before touch down, a gust of wind pushed the airplane off the left side of the runway, and it struck a ditch. Subsequently, the left horizontal stabilizer sustained substantial damage. The student pilot reported that the airplane had no preimpact mechanical malfunctions or failures that would have precluded normal operation.
