The pilot reported that, while en route, the motor glider began to lose altitude unexpectedly. He turned the motor glider toward an area where lift was expected, but it continued to descend. When the motor glider was about 300 ft above trees, he unfeathered the propeller and started the engine. The motor glider continued to descend due to a downdraft, and the pilot deployed the airframe parachute. Subsequently, the motor glider impacted vegetation, which resulted in substantial damage to both wings and the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the motor glider that would have precluded normal operation.
Probable Cause: The motor glider's encounter with atmospheric lift conditions that were not sufficient to maintain flight, which necessitated a forced landing and resulted in impact with vegetation. Contributing to the accident was the pilot's delayed decision to restart the motor glider's engine.
