Clermont, Florida 34711
Saturday, January 25, 1997 13:02 EST

NTSB Narrative Summary Released at Completion of Accident

The pilot elected to be towed aloft, as a cold front was approaching. While on final approach to land, the glider encountered a wind gust, which resulted in an uncommanded left bank and a 120-degree change in direction. The pilot recovered, then landed the glider in trees short of the runway. The gliderport owner stated that he was just about to cancel flight operations when the accident occurred.

NTSB Probable Cause Narrative

the pilot's improper planning/decision by electing to be towed aloft with a cold front nearby, which resulted in an in-flight encounter with wind gusts from the nearby cold front and subsequent in-flight collision with trees.
