NTSB narrative
The glider made an off-airport landing on a dirt road in crosswind conditions with rising terrain to the right, and ground looped. While soaring, the glider encountered sinking conditions and could not maintain sufficient lift for a landing at the departure gliderport. After determining that he was unlikely to be able to return to the departure airport, the pilot made a forced landing on a fire service road. During the landing rollout, due to a combination of rising terrain and an existing crosswind, the right wing lifted up, and the left wing contacted the ground, and ground looped.
Probable cause
loss of thermal lift during flight that resulted in a forced landing in an area without suitable landing terrain. Also causal was the pilot's inadequate compensation for the existing crosswind.

- 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. 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.
