NTSB narrative
The pilot was flying the airplane on the second leg of a visual flight rules cross-country trip, which he flew at an altitude of 3,500 feet in order to remain below an overcast ceiling. Approaching the destination airport, the pilot began a cruise descent and, about 10 miles from the airport, began configuring the airplane for landing. The pilot reduced engine power to about 1,500 rpm, set the mixture to full rich, but did not activate the carburetor heat. The engine then lost power, and the pilot subsequently performed a forced landing to a field. During the landing, the nose landing gear struck a ditch. Responders noted that fuel was recovered from the airplane following the accident; the engine was run after the accident with no anomalies noted. The temperature and dew point reported on the surface at an airport located about 21 nautical miles from the accident site were conducive to carburetor icing at both glide and cruise power settings.
Probable cause
The pilot did not apply carburetor heat during approach to landing, which resulted in a total loss of engine power due to carburetor icing.

- 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.
