Aircraft Accident/Incident Report

Spooner, Wisconsin 54801
Saturday, December 25, 2010 14:00 CST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that prior to landing, he performed two low level passes to determine a safe landing area on the frozen lake. He said that during the landing, the left landing gear ski touched down and he heard a bang as the left ski impacted a snow-covered raised ice ridge. He slowed the airplane for the landing rollout and the airplane came to rest upright. A postaccident examination of the airplane revealed that the landing gear box structure was bent and the bulkheads were damaged. The examination did not disclose any evidence of a mechanical malfunction. The pilot reported that he should have landed the airplane in the middle of lake which likely would have had less slush and rough ice.

NTSB Probable Cause Narrative

The pilot's selection of unsuitable terrain for landing on a snow-covered lake.
