What was found
DURING INSTALLATION OF FUEL LINE CROSSFEED KIT NR SK340-31-6, REMOVAL OF THE OLD LINES REVEALED THAT TWO LINES HAD NEARLY BEEN WORN THROUGH DUE TO CONTACT WITH INSPECTION PANEL SCREWS. THE ORIGINAL TUBING WAS PROTECTED BY THE ABRASION CUSHIONS, BUT THE EXTENT OF DAMAGE WAS NOT EVIDENT UNTIL THE CUSHION WAS PEELED OFF. VERY LITTLE CLEARANCE IS AVAILABLE AT THIS POINT, AND NEARLY IMPOSSIBLE TO DETECT ANY DAMAGE DURING INSPECTIONS. IF THIS CONDITION GOES UNDETECTED, THE NEW TUBING WILL ALSO BE DAMAGED. NUTPLATE/SCREW CLEARANCE FROM FUEL TUBING MUST BE VERIFIED. (X)
