NTSB narrative
THE AIRCRAFT WAS AIRBORNE WITH A PRIVATE PILOT ON THE FLIGHT CONTROLS IN FRONT AND A CFI IN THE REAR SEAT. THE CFI SAID HIS PURPOSE WAS TO OBSERVE PILOTING TECHNIQUE AND JUDGEMENT WITH NO FORMAL INSTRUCTION PLANNED. THE PRIVATE PILOT TOOK THE GLIDER BEYOND GLIDING DISTANCE TO THE DEPARTURE AIRPORT AND ALTHOUGH THE CFI SAID HE PROTESTED THE PILOT'S ACTION, HE ALLOWED IT TO HAPPEN. WITH THE PRIVATE PILOT STILL ON THE CONTROLS, THE GLIDER WAS SET UP FOR A PRECAUTIONARY OFF AIRPORT LANDING IN A FIELD AND ENCOUNTERED AN AREA OF SINK. THE GLIDER STRUCK A TREE, SPUN AROUND AND HIT THE GROUND NOSE FIRST.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN ADEQUATE CLEARANCE FROM TREE DURING THE PRECAUTIONARY LANDING. FACTOR WAS A LOSS OF THERMAL LIFT.

- 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.
