Capt. Ben Smith Airfield - Mon Airport
Aircraft Accident/Incident Report

Monroe City, Missouri 63456
Monday, July 25, 2011 11:30 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot stated that before the airplane descended to an intermediate cruise altitude, he selected carburetor heat and noted a normal decrease in engine speed. He then deselected carburetor heat and descended to 5,500 feet mean sea level. About 20 minutes after the descent, the engine ran rough and subsequently lost power. The pilot was unable to regain engine power by changing fuel tanks and he performed a forced landing to a corn field. Examination of the airplane revealed no anomalies that would have resulted in a loss of engine power. The conditions about the time of the accident were conducive to carburetor icing at glide power. The reason for the loss of engine power could not be determined.

NTSB Probable Cause Narrative

A total loss of engine power for undetermined reasons.
