Accident Summary
During maneuvering at approximately 100 feet above ground level (AGL), the pilot added power to out-climb rising terrain. Shortly after the power application, the engine began to run rough, prompting the pilot to apply carburetor heat. The use of carburetor heat resulted in a further loss of power, leading the pilot to return the carburetor heat to the off position. He then attempted to remedy the suspected carburetor icing by cycling the carburetor heat on and off.
Sequence of Events
When these actions did not restore the engine to full power, the pilot decided to attempt an emergency landing in a nearby clearing. While on final approach to the clearing, still approximately 20 feet AGL, the aircraft stalled/mushed into the terrain.
Carburetor Icing Conditions
According to the DOT/FAA Carburetor Icing Probability Chart, carburetor icing could be expected at the temperature and dew point present at the accident site at the time of the event.
