## Discrepancy

PITOT HEAT INSULATION, BURN MARKS WERE FOUND ON  PITOT PRESSURE LINE.  CONDITION RESULTS FROM HAVING PLASTIC LINE CONNECTED TO HEATED PITOT MAST. THE SB CORRECTS THIS BY ADDING PLASTIC SPIRAL WRAP TO LINE AND POWER WIRES AT THE PITOT MAST.  THIS PREVENTS PITOT LINE FROM DIRECTLY CONTACTING  HOT PARTS OF PITOT MAST, BUT SPIRAL WRAP INSULATION IS MADE OF SAME MATERIAL AS ORIGINAL PITOT LINE AND SUBJECT TO SAME HEAT DAMAGE.
