THE LOCAL WEATHER AT THE TIME OF THE ACCIDENT REPORTED A TEMPERATURE OF 64 DEGREES F AND A DEW POINT OF 60 DEGREES F. WHEN THESE FIGURES ARE PLOTTED ON A GRAPH WHICH DEPICTS THE PROBABILITY OF ENCOUNTERING CARBURETOR ICING, IT SHOWS A PROBABILITY OF 'SERIOUS ICING AT CRUISE POWER'.
THE IMPROPER USE OF CARBURETOR HEAT CONTROL, WHICH RESULTED IN A LOSS OF ENGINE POWER AND SUBSEQUENT EMERGENCY FORCED LANDING AND COLLISION WITH A FENCE. A FACTOR TO THE ACCIDENT WAS WEATHER CONDITIONS SUITABLE TO FORMATION OF CARBURETOR ICING.
