N77MA

While returning from a cross-country glider flight, the pilot reported losing lift and encountering downdrafts along his route. He elected to make an off-airport landing. During the landing approach, the glider impacted the top of a tree at approximately 12 feet above the ground; subsequently, it impacted terrain on the chin of its' fuselage and came to rest in an upright position. The force of the impact resulted in the separation of both wings. Examination of the glider revealed that the fuselage, canopy, and wings were structurally damaged.
