The pilot was cruising the local area about 1,000 feet agl, at 2,500 rpm, when the airplane suddenly started to descend. Although he hadn't noticed any evidence of strong winds, he was on the lee side of a peak. He turned to avoid the wind shear and applied full power, but his descent continued. The airplane collided with 100-feet tall trees after he maneuvered to avoid hitting one straight on with the cabin area.
Probable Cause: the pilot encountered a mountain wave at an altitude too low to maintain clearance from trees.
