Narrative:
The glider overran the end of the runway while landing and impacted a dirt mound. The pilot reported that he was obtaining flight instruction for the addition of a glider rating and the accident occurred during his first solo flight. The pilot stated the flight was uneventful until he turned onto final approach. The pilot reported that he was high on final and had to slip to lose altitude. The pilot stated that during the slip the glider had "picked up some airspeed." The pilot reported that the glider landed "long, fast, and as a result hit the mound at the edge of the airport perimeter dirt road." The pilot stated that several witnesses recalled not seeing the spoilers deployed during the final approach and landing. The pilot surmised that he had mistakenly repositioned his hand on the flap lever and as a result had been raising and lowering the flaps instead of the spoilers.

Probable Cause: The pilot's failure to extend the spoilers and his inadvertent use of the flaps during final approach, which resulted in the proper touchdown point being exceeded due to excessive airspeed. A factor to the accident was the dirt mound.
