The NTSB's narrative final · quoted from the NTSB record

The student pilot was on a solo training flight. The student flew in the local practice area and then returned to the departure airport for touch-and-go takeoffs and landings. The student completed one landing uneventfully. On the second landing, as the student flared, the airplane ballooned to approximately 20 feet above ground level. The airplane dropped hard and the nose and right wing impacted the runway, followed by the left wing. A postaccident examination revealed that the wing spar sustained substantial damage. The student reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
