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 he was practicing short field landings and configured the airplane with full flaps on the approach. The student pilot reduced power too early for the airplane configuration, which caused a loss of airspeed and a subsequent hard landing. During subsequent annual maintenance, a mechanic noted that the firewall was bent. The student pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
