Friday, June 11, 2010 16:00 PDT
NTSB Narrative Summary Released at Completion of Accident
The pilot stated that during cruise flight in the glider he encountered significant sinking air that prevented him from being able to make his destination glider port. He elected to make an off-field landing into a field. During the landing roll, the left wing contacted the ground and turned the glider to the left. During the turn, the glider's tail assembly separated from the fuselage. There was substantial damage to the tail structure.
NTSB Probable Cause Narrative
The pilot's encounter with an area of degraded lift during cruise flight, resulting in a forced off-airport landing.
