Thursday, June 19, 2003 12:32 PDT

NTSB Narrative Summary Released at Completion of Accident

The glider impacted trees and mountainous terrain while trying to cross a ridgeline. The glider had released from the tow plane about 1 minute prior to the accident. The glider was equipped with a GPS Flight Data Recorder, which recorded the total duration of the flight as 6 minutes 28 seconds. The last data recorded was at an altitude of 5,941 feet mean sea level (msl), the ground speed was 59 mph. The last recorded location of the glider was 2,000 feet laterally, northwest of the accident site. The elevation at the accident site was 5,798 feet msl. No unusual or adverse weather conditions were reported in the vicinity. No preimpact malfunctions or failures were identified during examination of the wreckage. Lower terrain was located to the rear of the pilot's attempted flight track.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate terrain clearance altitude and his delayed remedial action by not turning away from the ridge when a lack of lift became apparent..
