Aircraft Accident/Incident Report

Warner Springs, California 92086

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, his release from the tow plane was normal. He released the tow rope at 7,100 feet mean sea level (msl) while over a 6,500-foot msl mountaintop for a planned 1/2-hour sightseeing flight. Little to no indication of lift was noted in the area, and the pilot reversed course. When the glider had descended to 6,900 feet msl and was continuing to rapidly descend, the pilot again reversed course toward lower elevation terrain. The glider’s altitude was insufficient to clear a ridgeline. On the side of the mountain, about 6,400 feet msl, the glider impacted rocks, trees, and shrubs, which resulted in the glider’s wings breaking.

NTSB Probable Cause Narrative

The pilot’s inadequate altitude to clear a ridgeline while maneuvering over a mountainous area.
