Aircraft Accident/Incident Report
Dansville, New York 14807
Saturday, July 22, 2000 12:00 EDT
NTSB Narrative Summary Released at Completion of Accident
The glider was towed to 1,500 feet, and released. The pilot flew 'some' circles looking for lift and found a 'weak' thermal at 200 feet. The location of the thermal was west of a ridgeline that ran southwest. The glider then climbed to 1,000 feet and began to drift from the winds aloft. The pilot attempted to find lift off of the ridgeline, but only encountered sink. The glider began to lose altitude and impacted trees. The pilot reported a total flight experience of 2,177 hours, all in gliders.
NTSB Probable Cause Narrative
The pilot's improper in-flight decision to continue the flight with an unfavorable wind. A factor related to the accident was the loss of thermal lift.
