What was found
DURING A PHASE INSPECTION IT WAS NOTED THAT THE EXHAUST HEATSHIELD FORWARD OF THE TURBO COMPRESSOR HAD CHAFED AN AREA .1875 INCH X .3125 INCH THROUGH THE ENGINE MOUNT TRUSS. THIS WAS CAUSED BY THE HEATSHIELD MOUNT BREAKING ALLOWING THE HEATSHIELD TO DROP ONTO THE TRUSS. WE HAVE INCORPORATED AN INSPECTION OF THIS AREA INTO OUR INSPECTION PROGRAM.
