Accident Details
A glider experienced a loss of directional control during its approach to land. The aircraft drifted off the runway centerline, and the left wing made contact with a tree. The glider subsequently landed hard on the runway.
Sequence of Events
According to the investigation, the student pilot was unable to correct the deviation from the centerline. His control input resulted in a cross-controlled condition, causing the glider to drift further off the intended path. In an effort to avoid a tree, the pilot maneuvered the glider, which induced an aerodynamic stall. No mechanical anomalies with the glider were reported.
The incident occurred on approach, and the pilot noted no preexisting issues with the aircraft.
