Aircraft Accident/Incident Report

Mesquite, Nevada 89024
Saturday, June 15, 1996 17:30 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot and 11 other glider pilots planned to fly nonstop on a 500 kilometer flight from their point of departure, after an aero tow to 7,000 feet mean sea level. No communication difficulties or control problems were reported during periodic radio contacts between the glider pilot and the ground crew. En route, some of the glider pilots experienced turbulence and occasional downdrafts. Subsequently, the glider collided with rough terrain near a ridge line. There were no witnesses to the accident. The pilot's son indicated that his father was apparently unable to locate sufficient lift to continue his flight for an additional 11 miles to the destination airport.

NTSB Probable Cause Narrative

improper in-flight planning/decision by the pilot, which resulted in his being forced to land in an area with unsuitable terrain. Factors relating to the accident were: the lack of available (thermal) lift, downdraft(s), and the resultant lack of suitable terrain for an off-airport (emergency) landing.
