According to FAA Inspectors, the student pilot was operating in weak ridge conditions and encountered a sinking air mass while manuevering along a ridgeline. In so doing, the right wing of the glider struck a tree. The pilot was able to continue the flight and landed at Dillingham Airfield without further incident. An off-duty FSDO supervisor saw the aircraft in the hangar and noticed damage to the aircraft.
Probable Cause: the student pilot's misjudgement of descent rate and terrain clearance while manuevering along a ridgeline. Factors in the accident were the downdrafts and the mountainous/hilly nature of the terrain.
