NTSB narrative
The pilot reported that the glider was towed to 500 feet AGL, and released. He said that when he started his turn, the left wing dropped, and the glider entered a spin to the left. He applied opposite rudder, and the glider recovered after two turns. He said shortly thereafter he became disoriented, and does not remember anything else. A witness said that the glider entered another spin, about 100 feet AGL, and struck the ground at the approach end of runway 01. The pilot reported over 10 hours in gliders including 1 hour in make and model. He reported that there was no mechanical malfunction with the glider. According to the FAA, the glider was being flight tested, and had flown six times on the day of the accident.
Probable cause
The pilot's failure to maintain adequate airspeed which resulted in an inadvertent stall/spin. A related factors was the pilot lack of familiarity with the airplane.

- 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.
