NTSB narrative
The flight instructor reported that his student was practicing landings, and the airplane touched down right of the runway centerline and began to bounce as the student attempted to realign with the centerline. The flight instructor indicated that a wind gust was likely responsible for the initial bounce, but the airplane continued to bounce with an escalating intensity. He noted that on the third or fourth bounce he assumed control of the airplane in order to abort the landing. He reported that before he could establish a climb the airplane experienced an additional hard landing. He regained control and landed the airplane without further incident. The operator reported that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation of the airplane.
Probable cause
The flight instructor’s delayed remedial action to the student pilot’s bounced landing and subsequent loss of aircraft control.

Source notes (4)
- 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.
