During initial climb the engine experienced a loss of power and the pilot executed a forced landing. During the forced landing the tailwheel contacted a power transmission line. The pilot stated he performed a check of the engine and flight controls prior to the takeoff roll, including a check of the carburetor heat, magnetos, oil pressure and engine temperatures. The pilot reported the airplane had approximately 16 gallons of fuel prior to the accident flight. The engine was test-run successfully, running smoothly at all power settings and producing a maximum rpm of 2,100. A pilot with extensive experience in the accident airplane make and model reported, "I learned many years ago that if I were sitting idling, or just [taxing], waiting for takeoff, in hot and humid air, that it was necessary to keep the carburetor heat on during idling to prevent formation of ice in the venturi throat of the carburetor. If not done, there would be a loss of power on takeoff and climb out. It takes only a minute or so for such ice accumulation to occur in some cases." According to a carburetor ice potential chart, the weather conditions were conducive for serious icing during decent power.
Probable Cause: The partial loss of engine power due to carburetor icing. Factors to the accident include the weather conditions conducive to carburetor icing and the transmission wire.
