Aircraft involved

Probable cause & findings

The glider's loss of lift as a result of unfavorable wind conditions for glider operations, consequently resulting in a collision with trees.

Factual narrative

According to the pilot, while maneuvering the glider about 2,900 feet above ground level, the pilot determined that the wind conditions were not conducive to sustain flight and turned toward the runway in order to establish an approach. He recalled that while maneuvering toward the runway, he encountered downdrafts and began to lose altitude rapidly. He reported that he issued a mayday call about ¾ of a statute mile from the runway, established a nose up attitude to decrease the airspeed, and the glider impacted the trees. The glider sustained substantial damage to the right wing and fuselage. The pilot reported that there were no mechanical failures or anomalies with the glider prior to or during the flight that would have prevented normal flight operation.
