Aircraft involved

Probable cause & findings

The student pilot's improper flare, which resulted in a hard landing.

Factual narrative

The student pilot was on a solo training flight. The student and a certified flight instructor reviewed weather and additional flight information prior to the flight. The student flew in the local 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, the airplane drifted across the runway and it climbed approximately 20 feet above ground level during the initiation of the flare. The airplane dropped and the nose and right wing impacted the runway, followed by the left wing impacting the pavement. A post accident examination revealed that the wing spar was damaged. The student pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. The student pilot was on a solo training flight.
