What was found
MAIN FUEL LINE WAS REMOVED TO FACILITATE REPLACEMENT OF THE LT WING INBD WHEEL WELL KEEL. THE LINE WAS CHAFED APPROX HALF WAY THRU WHERE IT PASSES THRU THE KEEL. THIS AREA IS VERY DIFFICULT TO INSPECT AS IT IS ABOVE AND BEHIND THE MLG. THE RT WING MAIN FUEL LINE WAS INSPECTED AND FOUND TO BE CHAFED ALSO. BOTH LINES WERE REPLACED. SUGGEST CLOSE INSPECTION OF THESE LINES AT WING / WHEEL WELL INSPECTIONS.
