NTSB narrative
The Certified Flight Instructor (CFI) reported that she was demonstrating a landing approach in the glider without the use of dive-brakes. The CFI stated that that the glider landed long, and during the landing roll, it became evident that the aircraft would not stop before the end of the runway. The CFI reported that in order to avoid overrunning into a corn field at the end of the runway, she deployed the dive-brakes and turned the aircraft to the right towards an open flat field. The aircraft impacted between two trees on the right side of the runway. Inspection of the wreckage revealed no pre-accident flight control anomalies.
Probable cause
the misjudged planned approach and the evasive maneuver attempted by the pilot-in-command. A factor was the presence of trees.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1999-07-09.
