On March 10, 2002, at 1010 eastern standard time, a Schweizer SGS 1-26A glider, N3878A, was substantially damaged during a forced landing near Strausburg, Virginia. The certificated private pilot received minor injuries. Visual meteorological conditions prevailed for the flight which originated at the Front Royal Airport (FRR), Front Royal, Virginia, at 1000. No flight plan was filed for the local personal flight conducted under 14 CFR Part 91. According to the pilot, the glider was towed to altitude, about 3,800 feet, and when it was released, he flew towards the northeast portion of the Massanutten Ridge to use the "booming ridge lift." As the glider approached the ridge, it began to lose altitude, and the pilot found there was "no useable lift." The pilot performed a forced landing to a field, which was oriented on a 300-degree heading. He flew a traffic pattern approach to the field and during the downwind leg, the glider continued to lose altitude. As the pilot made a right turn onto the base leg of the traffic pattern, the glider's right wing struck a tree and it impacted the ground in a 70-degree nose down attitude. The pilot stated that he received an "outlook briefing" about 24 hours before his flight, which forecasted the winds to be from 290 degrees at 20 knots, with higher gusts. He did not receive an additional weather briefing; however, his visual observation of two wind socks at the airport indicated the winds were in agreement with the forecast. The pilot reported about 90 hours of total flight experience, all of which were accumulated in gliders. He also stated there were no mechanical deficiencies with the glider. The glider was examined by a Federal Aviation Administration (FAA) inspector. According to the inspector, substantial damage was noted to the nose of the glider. The winds reported at Front Royal, about 7 miles to the southwest, at 1000, were from 280 degrees at 21 knots gusting to 27 knots.
