What happened
During a landing approach, a student pilot was operating the flight controls of a glider. During the maneuver, the aircraft began to drift to the right of the runway centerline. As the deviation from the centerline increased, the instructor pilot took control of the aircraft.
The instructor attempted to correct the deviation using full deflection of the flight controls; however, the aircraft continued to drift rightward. The right wing tip of the glider subsequently struck trees located approximately 25 feet from the edge of the runway. Following the impact, the aircraft spun and came to rest in the trees at an altitude of approximately ten feet above the ground. There were no injuries reported.
