What happened
During a landing attempt, a glider sustained substantial damage upon contact with the terrain. The flight involved a pilot candidate and an FAA examiner, both of whom were not injured.
The pilot candidate reported that the base leg was turned too early, which resulted in the aircraft being too high on final approach. In an attempt to correct the altitude, the pilot tried to slip the aircraft, but the excess altitude persisted. As the aircraft traveled down the runway, it became apparent that an overshoot of the runway was imminent.
At that point, the FAA examiner took control of the aircraft and attempted to execute a 180-degree turn while instructing the pilot to monitor the airspeed. During this maneuver, the aircraft continued the turn with the right wing down. The aircraft caught a bank, which caused the glider to ground loop. The aircraft came to rest facing west. Following the event, the occupants exited the aircraft and confirmed they were unhurt.
At the time of the accident, the wind was variable at 6 knots.
