NTSB narrative
Two miles north of the destination airport, while cruising at 2500 feet, the pilot noticed that the engine rpm had dropped, followed by a total loss of engine power. Attempts to restore engine power failed. The pilot selected a forced landing area, and while maneuvering for the emergency landing, the right wing struck a tree and the airplane came to rest in a freshly plowed field. During the on-site phase of the wreckage examination, a substantial amount of fuel was discovered in the fuel tanks. No aircraft system malfunctions or component failures were noted during the on site examination and during the follow-up examination of the engine assembly. The pilot recalled that the outside air temperature at 2500 feet was 25 degrees. A review of weather data from the nearest reporting facility, 30 miles south of the accident site, reported a temperature of 40 degrees. Carburetor heat was last used about 45 minutes before the loss of engine power; the carburetor heat lever was in the cold position when the engine lost power. A review of weather data failed to disclosed conditions favorable for the formation of 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.
