According to the glider pilot, while skirting rain showers, he was unable to find lift and made an off-airport landing. The pilot made a straight in approach to a field and noticed that power line poles lined the west side of the field. He made his approach just to the east of the poles so that he would have access to a road and could load the glider onto a transport trailer. The glider touched down on the dirt field, drifted toward the power line poles, and the left wing struck a guy wire that ran perpendicular to the poles. The glider sustained substantial damage to the left wing and the left side of the fuselage near the wing root. Per the National Transportation Safety Board, Pilot Aircraft Accident Report, in the recommendation section, the pilot asserted that the accident could have been prevented if he had not landed so close to the poles. Further, he should have chosen a field earlier when he had more altitude, circled the field, and landed near the center. The pilot reported that there were no mechanical malfunctions or failures with the glider that would have precluded normal operation.
