Incident Overview

During a cross-country flight, the pilot descended to overfly a lake along the route. While flying at low level into the setting sun, the airplane's right main landing gear contacted a marked power line approximately 70 feet above the lake's surface. The impact separated the right landing gear and broke an engine mount.
