What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
At cruise aircraft failed to maintain power to sustain flight. Pilot landed the aircraft in a snow covered field causing damage to right wingtip and both propeller blades were bent. All damage noted was caused by impact on landing. Engine timing, presence of fuel, spark plugs, and cylinder compression were determined to be in normal working order. Pilot reported possible carb ice conditions and applied partial carb heat with no noticeable affect in RPM. Normal procedure is full on or full off. Cause of power loss could not positively be determined.
