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 stated that this was his fourth solo flight and that he had accumulated about 2 hours of solo flying experience. He flew to a nearby airport for practice touch-and-go landings and takeoffs and was planning a standard rectangular pattern. As he approached the airfield, a tower air traffic controller instructed him to perform a straight-in approach. This was the student pilot’s first attempt at a straight-in landing, and he had difficulty stabilizing the airplane’s flight path before touchdown. The airplane landed hard, bounced, and departed the left side of the runway. The airplane rolled into muddy terrain, bending the nose wheel landing gear mounting structure and the engine firewall. The pilot did not report any mechanical anomalies that would have precluded normal operation.
