NTSB Narrative Summary Released at Completion of Accident
According to a Federal Aviation Administration inspector, the pilot experienced a loss of lift while soaring and performed an
off-field landing to a pasture. During the landing, a gust of wind blew the glider down an embankment and into a barbed wire fence. During the impact with the fence, the left wing sustained leading edge damage, and the empennage separated partially from the fuselage. A postaccident examination of the glider and its systems revealed no preimpact malfunctions or failures.
NTSB Probable Cause Narrative
The loss of directional control during an off-field landing in gusting wind.
