NTSB narrative
The pilot was practicing low approaches when he experienced a partial loss of engine power during climb out. He continued onto the downwind leg where he applied carburetor heat and determined the loss of power was a result of carburetor ice. The pilot shortened the downwind and base legs, and decided to land on the grass alongside the paved runway. He stated that the approach was high and fast and he was more comfortable landing on the grass as the airplane was equipped with tundra tires. The airplane nosed over during the landing when it contacted standing water on the grass. The right wing of the airplane was substantially damaged. A review of the FAA Carburetor Icing chart revealed the conditions were conducive to serious icing at descent power.
Probable cause
The pilot's decision to land on the grass which contained standing water. Contributing to the accident was the partial loss of power due to carburetor ice.

- 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.
