NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
During the solo instructional flight, the student pilot landed hard, which resulted in deformation of the airplane's firewall. A witness observed the pilot's landing and reported that following the first touchdown, three additional pilot-induced oscillations occurred. During this event engine power increased, and the elevator moved up and down. On the third bounce, the witness heard the airplane's propeller impact the runway. The student pilot, who had about 2.2 hours of total solo flying experience, did not report any mechanical malfunction with the airplane during the accident flight.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot's improper flare, which resulted in a hard landing. Contributing factors were his improper recovery from the subsequent bounced landing and pilot-induced oscillations. Full narrative available
