What happened
The pilot arrived at the intended destination and immediately entered the traffic pattern to prepare for a landing. During the final approach, the pilot noted that the airspeed was higher than optimal. Consequently, the aircraft touched down further down the runway than planned.
As the aircraft decelerated along the pavement, it became clear that there was not enough remaining distance to bring the airplane to a complete stop before the end of the available surface. To avoid overrunning the runway, the pilot made the decision to turn the aircraft off the paved area.
During this maneuver, the aircraft lost directional control and ground looped. The uncontrolled rotation caused one of the wings to strike the ground, resulting in damage to that wing.
