What was found
DURING A PHASE INSPECTION, THE LEFT CROSSOVER TUBE WAS POUND CHAFED BY THE ENGINE MOUNT TRUSS (PN 102-910026-131). THE CHAFING WAS APPROXIMATELY HALFWAY THROUGH THE WALL THICKNESS. WE HAVE A SPECIAL INSPECTION TO CHECK THE HEATSHIELD FOR CHATING IN THIS SAME AREA, OTHERWISE THIS WOULD HAVE PROBABLY BEEN MISSED DUE TO ITS INACCESSIBILITY BEHIND THE INDUCTION FILTER HOUSING, THE PART WILL BE REPLACED TO SEE IF A DIFFERENT TUBE HAS THE SAME PROBLEM. OTHER AIRCRAFT IN THE FLEET WERE CHECKED WITHOUT DEFECTS NOTED.(K)
