Analysis

According to the pilot, she flew the glider into the landing pattern and checked the airbrakes. She lined the glider up to land on the grass runway, but landed close to its right side where other aircraft were parked. Upon touchdown, the glider bounced. The pilot added left stick and rudder, but the glider veered to the right and hit an airplane parked off side of the runway, resulting in substantial damage to the glider's right wing. The pilot did not report any preexisting mechanical anomalies that would have precluded normal operation.
