The pilot was aware that there were power lines located in an area where he was spraying for gypsy moths. A park ranger saw the airplane make several passes up and down a river. As the airplane began it's third pass, it was headed toward the power lines and a ridge line. The airplane was in a descent, the wings were level, the airplane was spraying, and the engine sounded strong. The ranger lost sight of the airplane behind the ridge line, but 3-5 seconds later he saw smoke. Examination of the unmarked power lines revealed contact marks at the point where the wires crossed over the river. A 3-foot section of the left wing was found in the river downstream of the power lines. Examination of the wing section revealed spiraled striations at the leading edge of the wing and left aileron.

Probable Cause: The pilot's failure to maintain visual separation from a set of known, yet unmarked power lines.
