NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
The pilot departed from a private airstrip in a wheel/ski-equipped airplane on a local area flight. During the flight, he elected to land on an ice-covered, frozen lake, and, due to the bare ice conditions, he elected to land in a wheel configuration instead of ski configuration. During the landing roll, as the airplane slowed, the left tire broke through a layer of thin ice atop several inches of water, and the airplane veered left. The pilot applied engine power in an attempt to correct the veer, but the airplane subsequently ground-looped to the left, sustaining substantial damage to the empennage and fuselage. The pilot reported no preaccident malfunctions or failures with the airplane that would have precluded normal operation.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's selection of unsuitable terrain for an off-airport landing, which resulted in a ground-loop. Full narrative available
