| Confidence Rating: |  Accident investigation report completed and information captured |
Before takeoff, the pilot performed an engine run-up and noted after removing carburetor heat, that the handle was 'loose.' During the initial climb, the engine experienced a partial loss of power and black smoke was noted coming from the exhaust. While maneuvering to return, the airplane stalled and crashed into water. Examination of the engine revealed no mechanical failure or malfunction. The carburetor heat control cable was found to be separated from the carburetor heat control arm assembly. Disassembly of the carburetor revealed evidence of previous fuel leakage from the carburetor bowl vent which would introduce extra fuel into the air induction system. Also, the adjustment tab of the metal float and the head of the float needle valve were determined to be worn. The carburetor was installed on the engine on June 3, 1996, and had accumulated 1,246 hours since installation at the time of the accident. The accepted procedure after removing carburetor heat is to note that the engine rpm's increase either to the setting before the heat was applied, or to a greater rpm is carburetor ice was present. The worn condition of the carburetor was known for the past 7 years, according to the pilot.
Probable Cause: The intentional operation of the airplane by the pilot and the company/operator with the known deficiencies in equipment (worn carburetor). Also, the poor preflight planning by the pilot for his failure to recognize that the carburetor heat control was inadvertently activated on takeoff and his inadvertent stall of the airplane while turning to reverse direction. Contributing to the accident was the separation of the carburetor heat control cable.
