NTSB narrative
The glider pilot reported that he was unable to find thermals that would provide suitable lift for continued flight. Subsequently, a field was selected that the pilot assessed was adequate for a successful landing. After overflying the field at 1,000 feet above ground level the pilot began his approach. The approach and touchdown were uneventful. During the landing roll, as the pilot deployed the speedbrakes and applied braking, the glider pitched forward and the left and right wings contacted crops that were located on either side of the glider's landing roll. The left wing engaged the crops more fully than the right wing and the glider yawed to the left before coming to rest. As a result, the empennage was substantially damaged. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airframe that would have precluded normal flight.
Probable cause
The glider's impact with crops during the off-airport landing.

- 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, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2011-07-21.
