NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot and a passenger were landing on a frozen lake at the conclusion of a cross-country flight. The pilot reported that overcast clouds and flat lighting conditions prevented him from seeing an approximate 3 feet high snow berm at the approach end of the landing area. The berm resulted from snow plowing operations to create an ice skating area on the lake. During the landing flare, the landing gear skis struck the top of the berm. The airplane came to rest on the ice and received damage to the landing gear and right wing lift strut.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

failure of the pilot to maintain sufficient altitude/clearance from a snow berm during the landing. The snow berm and flat light conditions were related factors.
