NTSB narrative
The pilot reported that the glider experienced a loss of lift during a cross country flight and he executed an off-airport approach and landing to a field. During the landing flare, the glider’s left wing struck a fence post. Subsequently the glider landed sideways and came to rest upright. Examination of the glider revealed that the left wing spar and the fuselage were structurally damaged. The pilot reported no mechanical anomalies with the glider’s flight control systems.
Probable cause
A loss of lift which necessitated a forced landing in a field.

- 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.
- API snapshot SHA-256: 8487c7a7547cb03bff64847dff4b588dd76da3aa3910d91c2a37bdfe740dd7c9; retrieved 2026-09-15T11:52:10.285Z.
