NTSB narrative
The glider pilot had released the glider from the tow plane prematurely at 1,500 feet MSL due to conflicting traffic. After 'thermalling with another glider for a while, he could not find much lift,' so he headed back to the airport to land. The pilot added that he was too low when he entered the downwind leg for runway 16; however, he estimated that he would be able to reach the approach end of the runway. In a written statement, he stated that he became distracted by a yellow glider that he thought was blocking the landing runway. The pilot reported that while maneuvering to land at the threshold for the 4,500-foot turf runway, he turned the aircraft onto the base leg prematurely; consequently the left wing impacted the ground nearly perpendicular to the runway near the threshold. Subsequently, the glider impacted the ground in a nose low attitude, bounced back in the air and impacted the ground in a tail low attitude, separating the tail section.
Probable cause
The pilot's misjudgment of the distance and altitude. Factors were the lack of thermal lift and his diverted attention while on downwind.

- 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.
