Analysis

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.
