Aircraft Accident/Incident Report

Russellville, Alabama 35653
Thursday, May 1, 1997 11:00 CDT

NTSB Narrative Summary Released at Completion of Accident

Approximately 4 hours into the flight, while on a long descent to the destination airport, the pilot experienced a reduction in engine power. The power reduction continued over a period of eight minutes and resulted in a complete loss of engine power. Following the loss of power, the pilot's attempts to restore full engine power, which included the application of carburetor heat, failed. The pilot selected a nearby paved road for an emergency landing. During the landing roll out, the right wing collided with a road sign, and the airplane swerved into an adjacent ditch and nosed over. Examination of the airplane failed to disclose a mechanical problem. Fuel was recovered from the fuel system. During the functional test of the engine, the engine operated normally through all power ranges. A review of current weather information revealed that weather conditions were favorable for the formation of carburetor icing.

NTSB Probable Cause Narrative

The loss of engine power for undetermined reasons. A factor was conditions were favorable for the formation of carburetor ice.
