Aircraft Accident/Incident Report

Tinicum Twnshp., Pennsylvania 19029
Sunday, May 6, 2001 9:47 EDT

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, this was his first flight in the make and model glider. The pilot soared the glider at 3,000 feet in the local area for about three hours. As the thermal lift began to dissipate, the glider began to descend. Realizing that he was at a low altitude and would not make it back to the airport, the pilot elected to make an off field landing. While maneuvering for the off field landing, the airplane struck a 5-foot high tree.

NTSB Probable Cause Narrative

The pilot's improper decision to delay his landing. A factor related to the accident was the loss of thermal lift.
