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

During landing of the student pilot's first solo cross country flight, the airplane bounced and began to drift to the left of the runway centerline. The student attempted unsuccessfully to correct the drift, and consequently performed a go-around. Images of the student pilot's go-around were captured by a security camera on the airport. Review of the captured images revealed that during the go-around, the airplane rolled and turned to the left, while simultaneously pitching up into a nose-high attitude. The airplane then pitched nose down while continuing to roll and turn left, before moving out of view of the security camera. A postaccident examination of the accident site revealed, that after moving out of view of the security camera, the airplane impacted the ground, 180 degrees off the runway heading, and nosed over. Examination of the airplane revealed that it had incurred substantial damage to the wings, fuselage, and engine firewall. No preimpact malfunctions of the airplane or engine were discovered.
