NTSB narrative
The sport pilot reported that, before departing on a cross-country flight, he contacted the flight service station for a weather briefing for his flight route. He then conducted a preflight inspection of the airplane, started it to allow it to warm up, and ran the carburetor heat before departing. The climb to cruise at 2,000 ft was normal. The pilot reported that, about 10 miles from the departure airport, the engine started to run "rough" and that he applied carburetor heat. When this did not have any effect on engine performance, he decided to return to the departure airport. He added that, during the return, the engine "power was very poor" and that the airplane was losing altitude rapidly. The pilot spotted a clear field nearby and performed a soft-field landing approach. Upon landing, the gear dug into the soft plowed field. The airplane continued forward on its belly, which resulted in substantial damage. The weather conditions were conducive to the accumulation of serious icing at any power setting. Although the pilot reported that he used carburetor heat, it is likely that the ice had already accumulated to the degree that the carburetor heat was insufficient to melt the ice and restore full engine power. An examination of the airplane and engine did not reveal any preimpact anomalies.
Probable cause
A partial loss of engine power due to carburetor icing and the subsequent forced landing on a rough/soft field.

- 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.
