Accident Details
A private pilot experienced a loss of engine power while reducing power during the landing approach. The pilot was unable to restart the engine and determined that gliding to the airport was not possible. A forced landing was attempted in a field, but the airplane collided with trees prior to landing. The impact caused the right wing to separate from the fuselage, and the aircraft came to rest inverted.
Pilot's Report
In the pilot's report to the National Transportation Safety Board, the block asking "Was there mechanical malfunction/failure?" was marked as "Unknown." In the recommendations section, the pilot wrote: "I believe I had carb ice—I think if I would not have reduced power to idle this would have prevented the accident."
Weather Conditions
The temperature and dew point at the accident site were recorded as 28°F and 19°F, respectively. An icing probability chart indicates that this combination is likely to produce moderate carburetor icing at idle power.
