Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

After being towed several miles west of the departure airport and to 4,300 feet MSL, the glider pilot released from the towplane. Shortly thereafter, he encountered a sink and turned west and north, away from the airport, during which the sink conditions did not abate. Having lost 1,100 feet in altitude, the pilot decided that he could not return to the departure airport, and once again turned west and north in search of lift. He then turned towards a plowed field in which to land but, still encountering sink conditions, landed 1/4 to 1/3 of a mile short in sagebrush covered terrain. During the landing roll the glider ground looped to the right damaging the tail-boom. The pilot reported that he should have immediately turned back to the departure airport when the heavy sink was encountered.

NTSB Probable Cause Narrative

The pilot's improper in-flight decision by not immediately seeking a safe landing site upon encountering the sink. A factor was the high vegetation (sagebrush).
