Analysis

Reportedly, the plt was flying at low altitude over a lake & had to pull up to cross over a dam. After crossing the dam, he began to descend, but the ultralight vehicle collided with power lines on the down river side of the dam. The power lines were about 135 ft above the terrain on that side of the dam. After hitting the lines, the vehicle flipped upside down & went into the ground with full power. An exam of the wreckage revealed evidence that the plt attempted to deploy the parachute that was attached to the airframe. The power lines were not marked & would have been hard to see with terrain features in the background.
