Aircraft Accident/Incident Report
Bryon, California 94514
Saturday, December 7, 2013 16:30 PST
NTSB Narrative Summary Released at Completion of Accident
The student pilot reported that during landing the glider touched down slightly left of the runway centerline. He engaged the brakes and steered the glider towards the right side of the runway to prepare for a turn. When he approached the taxiway entrance, he released the brakes and started to turn to the left. During the turn the left wing struck a runway sign; the airplane made a sharp left turn, exited the runway surface and came to rest on the grass. During the accident sequence, the left wing sustained substantial damage. The pilot reported no mechanical malfunctions or failures with the airframe that would have precluded normal operation.
NTSB Probable Cause Narrative
The pilot's failure to maintain adequate wing clearance from a runway sign while taxiing.
