The NTSB's narrative final · quoted from the NTSB record

The pilot made a touch and go landing. During climbout, the engine lost power. During the forced landing approach to an airport access road, the airplane struck a fence post and barbed wire. The engine then regained power, and the pilot taxied back to the ramp. A mechanic said he suspected carburetor ice as the cause of the power loss. The pilot said he applied carburetor heat towards the end of the approach for the touch and go landing, and closed it prior to lifting off. The temperature and dew point were 19 degrees C. and -4 degrees C., respectively. According to the Carburetor Icing Graph, this temperature/dew point combination is on the outer fringes of SERIOUS ICING AFFECTS GLIDE OR CRUISE POWER arc.
