What was found
THE PROBLEM WAS FOUND DURING AN INSPECTION TO FIND THE SOURCE OF A HEAVY FUEL SMELL IN THE AIRCRAFT CABIN. THE LEAK WAS FOUND IN THE FUEL LINE ON THE RIGHT SIDE OF THE CABIN AS IT ENTERED INTO THE AIRCRAFT CABIN THROUGH THE WING ROOT. THE CAUSE OF THE LEAK WAS A HOLE THAT HAD CORRODED THROUGH. THE CORROSION HAD OCCURRED DUE TO THE MOISTURE RETENSION OF THE OLD STYLE PAPER FUEL LINE LABEL. TO PREVENT THIS FROM RECURRING, THE OLD STYLE PAPER LABELS MUST BE REMOVED, AND THE FUEL LINE CLEANED, TREATED, AND NEW PLASTIC LABELS INSTALLED.
