What was found
DURING INSPECTION OF THE LT WING TIP FUEL TANK THE INTERNAL FUEL DELIVERY LINE WAS FOUND TO BE BROKEN AT THE INBOARD BULKHEAD ATTACH POINT (TACKWELD). THIS CONDITION IF RETURNED TO SERVICE WOULD NOT ALLOW THE FULL CONTENTS OF THE WING TANK TO BE TRANSFERED TO THE MAIN FUEL SYSTEM, APPROXIMATELY 1/2 OF THE TIP TANKS FUEL CONTENTS WOULD REMAIN IN THE FUEL CELL.
