Aircraft Accident/Incident Report

Sunday, July 13, 2003 16:00 EDT

NTSB Narrative Summary Released at Completion of Accident

During a glider flight, the pilot was over an airport about 30 miles from his intended destination airport, at an altitude of about 1,160 feet above the ground. The pilot overheard radio communications between other glider pilots in the area who indicated that conditions were "tougher" than they expected. The pilot elected to attempt to reach his destination airport; however, he was not able to locate adequate thermal activity to maintain altitude. The pilot attempted to divert to another airport; however, the glider continued to descend and he attempted a landing to a gravel pit. While on approach, the glider impacted trees and struck the ground.

NTSB Probable Cause Narrative

The pilot's improper in-flight decision to over fly a suitable landing area. Factors in this accident were weak thermal lift activity, and lack of suitable terrain at the time of the landing.
