NTSB narrative
DURING INITIAL CLIMB AFTER COMPLETING A TOUCH AND GO, THE PILOT REALIZED THAT THE AIRLANE WAS BARELY CLIMBING. HE IMMEDIATELY SCANNED THE INSTRUMENTS, CHECKED THE FUEL SELECTOR AND ALL ENGINE CONTROLS. THE ENGINE CONTINUED TO LOSE POWER. REALIZING THAT HE WOULD NOT BE ABLE TO RETURN TO THE AIRPORT TO LAND, THE PILOT DECIDED TO MAKE A FORCED LANDING ON A FROZEN, SNOW COVERED LAKE. WHILE LANDING, THE LANDING GEAR DUG INTO THE SNOW AND THE AIRPLANE NOSED OVER. POSTACCIDENT EXAMINATION REVEALED NO MECHANICAL ANOMALIES. A FUEL SAMPLE WAS TAKEN ON THE DAY OF THE ACCIDENT AND ICE CRYSTALS WERE FOUND IN THE SAMPLE. THE REPORTED TEMPERATURE WAS 2 DEGREES AND THE DEWPOINT WAS NEGATIVE 12.
Probable cause
the loss of engine power due to a blockage caused by ice. A factor in the accident was the snow.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
