During takeoff from a 3,500 ft MSL airstrip in carburetor icing conditions, the pilot applied carburetor heat at 50 ft AGL, causing the engine to stop. After deselecting carburetor heat, the engine ran rough, the aircraft lost altitude, and struck terrain during a left turn.

Departure and Conditions

The pilot initiated a takeoff from an airstrip located at an elevation of 3,500 feet mean sea level. The pilot later described the ambient conditions as 'optimum carb ice conditions,' with an outside air temperature of 40 degrees Fahrenheit and 'lots of moisture.' The carburetor heat control was selected to the 'off' position for the takeoff.

Engine Power Loss

During the initial climb, at approximately 50 feet above ground level, the pilot applied carburetor heat. Upon application, 'the engine died.' The pilot then deselected carburetor heat. The engine began to run roughly, and the airplane started to lose altitude.

Maneuver and Impact

In an effort to avoid trees, the pilot initiated a left turn. During this turn, the left wing and nose dropped, and the airplane subsequently impacted terrain. The electric stall warning system had been disconnected prior to the flight.
