NTSB narrative
During an instructional flight in a glider, the student was high on the final approach, deployed the spoilers and entered a forward slip. The flight instructor stated that shortly after, the student “suddenly and unexpectedly” pulled back on the control stick while the rudder and ailerons were cross controlled. The flight instructor immediately took control, pushed the control stick forward and closed the spoilers; however, insufficient altitude remained for a full recovery, which resulted in a hard landing and serious injuries to the instructor. The flight instructor reported that there were no preimpact malfunctions or anomalies that would have precluded normal operation.
Probable cause
The student pilot's failure to maintain an appropriate glide path to the runway.

- 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, coordinates, cause areas, damage. 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.
