What happened
The pilot was engaged in ridge soaring when the glider encountered a sudden wind gust. This turbulence caused the aircraft to drift over the crest of the ridge. Attempting to return to the windward side of the ridge, the pilot faced a wind shear that induced a stall. The glider subsequently entered a spin.
The pilot managed to recover from the spin at a low altitude. However, the aircraft then flew into an area of scrub oaks in a nose-down attitude. Following the incident, the pilot noted that flying faster could have avoided the stall.
The investigation
No mechanical examination details were provided in the source text. The narrative focuses entirely on the pilot's account of the flight conditions and the sequence of aerodynamic events leading to the crash.
Findings
The primary factors contributing to the accident were the encounter with wind shear over the ridge crest and the resulting stall and spin. The pilot's own assessment indicated that maintaining higher airspeed might have prevented the stall condition.
