NTSB narrative
The pilot reported that, after climbing to about 800 ft above ground level (agl), the engine suddenly stopped producing power. The pilot reported applying full carburetor heat and partial power was restored. The pilot then removed carburetor heat; again, the engine stopped producing power. The pilot applied full carburetor heat, and the engine regained partial power, but not enough to maintain altitude. The pilot made an emergency landing on a dirt road about three miles north of the airfield. During landing the left wing impacted brush and terrain along the road resulting in substantial damage to the left wing. A postaccident examination of the airframe and engine revealed no preaccident mechanical malfunctions or failures that would have precluded normal operation. Weather conditions at the time of the accident were conducive to carburetor icing at cruise power and serious carburetor icing at glide power. Although the pilot reported that he used the carburetor heat, it is likely that ice had already accumulated to the degree that the carburetor heat was insufficient to melt the ice and restore full engine power.
Probable cause
A partial loss of engine power due to the formation of carburetor ice as a result of the pilot’s improper use of carburetor heat.

- 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: local date, investigation status, coordinates, cause areas. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2024-10-25.
