Aircraft Accident/Incident Report
Elmira, New York 14903
Monday, July 7, 2008 14:00 EDT
NTSB Narrative Summary Released at Completion of Accident
The pilot stated that after his Schleicher ASK-21 glider was towed aloft to 2,000 feet and released, he flew too far from the airport traffic pattern. He said that during the return to the airport, he encountered a "sink and waterfall" effect, which caused a low approach, resulting in his inability to make it to the airport. Subsequently, there was a collision with terrain 100 feet short of the runway. The pilot added that there were no deficiencies with the performance and handling of the glider.
NTSB Probable Cause Narrative
The glider pilot's misjudged distance/altitude while soaring.
