Probable cause
The pilot’s failure to maintain clearance from an electric transmission line during the approach to land because he was distracted by the airplane’s broken and deflected landing ski. Contributing to the accident was the in-flight failure of the right ski connecting bolt and the subsequent ski deflection.

Read the full NTSB narrative
The pilot was returning from a weather observation flight when the right wheel/ski actuator connecting bolt broke and the ski deflected downward about 90 degrees. The pilot maintained control of the airplane; however, during the descent to the airport he realized that he was descending faster than he anticipated. He increased the airplane’s pitch angle in an effort to climb, but the airplane contacted a power line. The pilot continued to the destination airport and landed after two low passes. The airplane sustained substantial damage to the left wing. The pilot stated that he was aware of the power line, but was so focused on the ski deflection and maintaining control of the airplane that he did not even realize that the airplane had struck it. The failure of the wheel/ski actuator connecting bolt was likely due to the repetitive forces to the skis that typically occur in normal ski operation.
