Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

The pilot of the accident airplane was flying at 600 feet msl crossing a body of water when he noticed a loss of engine rpm. He pulled on the carburetor heat, and switched from the right wing fuel tank to the left wing fuel tank. The engine rpm increased momentarily, and then the engine quit. The pilot turned toward land, and made an emergency landing. During landing the airplane encountered a dirt berm, the left main landing gear collapsed, and the airplane nosed over. The meteorological conditions were, in part: temperature, 9 degrees Celsius; dew point, 7 degrees Celsius, with visible moisture. Under these conditions, a carburetor icing probability chart reflects serious icing at any power setting. During the postaccident examination the fuel selector valve was found with the left wing fuel tank selected. There was no usable fuel found in the left wing tank, and no evidence of any fuel leak was discovered.

NTSB Probable Cause Narrative

The pilot's selection of a fuel tank that did not contain a usable quantity of fuel. Factors associated with the accident are the dirt berm, meteorological conditions conducive to carburetor icing, and carburetor ice.
