NTSB Narrative Summary Released at Completion of Accident

The pilot made a forced landing on desert terrain adjacent to a pipeline. The glider landed hard on a mound, bounced back into the air, and struck the ground at a 30-degree nose down attitude. The pilot said that after release from an aero tow he was unable to find sufficient thermals to support continued flight and decided to return to the airport. He indicated that he had not realized that he had lost 1,000 feet of altitude since release from the aero tow and he was now too low to either make it back to the airport or to pick a more suitable off airport landing site. He chose to land near a pipeline, which appeared to be smoother than the surrounding area. The pilot also reported that the area was typical of the desert terrain, flat with small mounds and hills, and rocks.

NTSB Probable Cause Narrative

the pilot's in-flight decision to continue a flight with weak thermal lift activity, and his delayed recognition of a loss of altitude while attempting to find a thermal in which to soar. A factor in the accident was the lack of suitable terrain for the forced landing.
