NTSB narrative
The flight instructor reported that, during a simulated engine failure in the traffic pattern, with gusting wind conditions, the student pilot entered a forward slip on final approach. He added that 10 to 20 ft above the runway surface, "the wind gust we were riding suddenly halted wherein the aircraft began a rapid downward descent." The flight instructor reported that he "went for the flight controls to take command," but the student pilot at that same time applied back pressure on the flight controls. Subsequently, the airplane touched down hard, bounced, and the flight instructor performed a go-around. The flight instructor completed the subsequent traffic pattern and landing without further incident.
The engine mounts and firewall sustained substantial damage.
The flight instructor reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
An automated weather observation station at the airport reported that, about the time of the accident, the wind was from 170° at 16 knots, gusting to 24 knots. The flight instructor reported that the landing was on runway 15.
Probable cause
The student pilot's incorrect control application during landing after a simulated engine failure, which resulted in a hard, bounced landing, and the flight instructor's delayed action to perform a go-around in gusting wind conditions.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
