| Confidence Rating: |  Accident investigation report completed and information captured |
The airplane was departing from the 3,500 feet msl airstrip in what the pilot described as 'optimum carb ice conditions' of 40 degrees F with 'lots of moisture.' The carburetor heat control was 'off' for takeoff. At 50 feet above ground level on climb out, the pilot applied carburetor heat and 'the engine died.' She deselected carburetor heat, the engine began to run rough, and the airplane began to lose altitude. When the pilot began a left turn to avoid trees, the left wing and nose dropped, and the airplane impacted terrain. The electric stall warning had been disconnected.
Probable Cause: The pilot's improper use of carburetor heat during a takeoff in carburetor icing conditions. Factors associated with the accident were the pilot's decision to operate the airplane with known deficiencies (a disabled stall warning horn), an inadvertent stall, and the presence of carburetor icing conditions.
