Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
The glider pilot said that he approached the north end of runway 17 for landing. He said "there is a nominal amount of sinking air at all times near the North end of the runway. The day of the incident the sink was far greater than expected." He said that he landed approximately 200 feet short of the runway, and impacted a 3 foot high berm next to an irrigation ditch (which ran perpendicular to the runway) at approximately 50 knots. The glider was "catapulted" over the ditch. The pilot immediately nosed the aircraft down to avoid a stall. "The glider landed flat and hard, crushing the landing gear, then skidding to a halt 75 feet past the runway apron." The glider's keel beam and wing spars were broken.
NTSB Probable Cause Narrative
the pilot's inadequate in-flight planning resulting in the glider impacting terrain short of the runway, and the pilot's subsequent abrupt handling of the glider when it became airborne again, which resulted in a hard second landing. A contributing factor was the downdraft weather condition.
