A pilot flying at 600 ft msl over water experienced a loss of engine rpm. After applying carburetor heat and switching fuel tanks, the engine quit. During an emergency landing, the airplane hit a berm, collapsing the left main gear and nosing over.

Accident Sequence

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 the landing, the airplane encountered a dirt berm. The left main landing gear collapsed, and the airplane nosed over.

Meteorological Conditions

The meteorological conditions at the time included a temperature of 9 degrees Celsius and a dew point of 7 degrees Celsius, with visible moisture. Under these conditions, a carburetor icing probability chart reflects serious icing at any power setting.

Postaccident Examination

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.
