Incident Overview
A glider pilot participating in a competition reported encountering a weak frontal system, which resulted in insufficient lift to sustain flight. The pilot determined he had approximately 15 minutes of flying time before the glider would need to land. He selected a large field and established a traffic pattern to execute a landing.
Landing and Collision
The pilot accomplished a full stall landing. However, during the landing roll on terrain that sloped downward, the glider was traveling at about 40 knots when it collided with a ditch. The impact caused substantial damage to the glider's tailboom.
Post-Accident Report
The pilot stated that there were no mechanical malfunctions or failures with the glider that would have precluded normal operation. No further details about the cause of the accident were provided by the pilot.
