The wing of the glider struck a tree when the solo student pilot was correcting the flight path to align the glider with the runway centerline during the final approach. The density altitude was calculated at 4,215 feet. The student pilot had 15.2 hours of total flight time in gliders. He was endorsed for solo flight and had 2.4 hours of solo flight time in the glider. The operator reported that the accident could have been prevented by 'maintain[ing] adequate clearance over obstacles.'
Probable Cause: The pilot's failure to attain proper runway alignment of the glider resulting in failure to maintain obstacle clearance. A factor was the high density altitude.
