Confidence Rating: Accident investigation report completed and information captured
The aircraft experienced an engine failure after departure. The certified flight instructor (CFI) executed a forced landing on a road where the aircraft wing contacted a semi-truck. A postaccident examination revealed no preexisting anomalies with respect to the aircraft or aircraft systems. The CFI reported no mechanical malfunction. A weather report stated a temperature of 32 degrees F., and a dewpoint of 28 degrees F. According to the carburetor icing chart by Transport Canada, the temperature and dewpoint at the time of the accident fall within the range of serious icing potential. FAA AC 20-113 states, 'When the relative humidity is above 50 percent and the temperature is below 70 degrees F., apply carburetor heat briefly immediately before takeoff, particularly with float type carburetors, to remove any ice which may have been accumulated during taxi and runup.'

Probable Cause: The pilots failure to use carburetor heat during takeoff in weather conducive for serious carburetor ice. Factors were the weather that was conducive for carburetor icing and the presence of the truck that the aircraft impacted.
