Probable cause
The pilot's exceedance of the critical angle of attack on final approach in turbulent conditions, which resulted in an aerodynamic stall and collision with terrain.
NTSB analysis
The pilot of the glider reported that due to the lack of thermals, he decided to land on an off-airport field. The pilot further reported about 20 feet above the ground on final approach he encountered turbulence behind obstacles. Subsequently, the glider entered an aerodynamic stall and impacted terrain in a nose low attitude.
The right wing, fuselage, and canopy were substantially damaged.
The pilot did not report any mechanical malfunctions or failures with the glider that would have precluded normal operation.
