NTSB narrative
The airplane was in cruise flight, at 2,100 rpm, when engine power decreased, and the maximum attained was 1,400 rpm. The pilot applied carburetor heat, and turned back toward an open area "less than a mile back." The pilot completed the forced landing; however, during the rollout, the airplane went down an unanticipated hill, and the landing gear collapsed. The on-scene examination was limited to a damage assessment, as well as confirming that fuel and oil were present. The airplane was subsequently moved to the pilot's hangar, and after the insurance company took possession, there was no further examination. Weather, reported at an airport about 35 nautical miles to the east, indicated a probability of serious carburetor icing at glide power. FAA-P-8740-24, Tips on Winter Flying, noted that carburetor ice could manifest itself by a loss of rpm in fixed pitch airplanes. The response would have been to apply full carburetor heat; however, the engine could run roughly for a short time while the ice melted. In addition, light carburetor icing over a prolonged period of time could become serious.
Probable cause
Carburetor icing, which resulted in a partial loss of engine power. A factor was an unanticipated hill in the forced landing rollout area.

- 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, coordinates. 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.
