## Discrepancy

(CAN) DURING TROUBLESHOOTING OF A REFUEL SNAG, ONE END OF THE LT NR 7 FLAP PRIMARY TORQUE TUBE WAS FOUND WITH EXTENSIVE DAMAGE.  ELONGATED HOLES WHERE OBSERVED AT THE JUNCTION OF THE TUBE AND SPLINED SHAFT.  LOOSE FASTENERS HAVE LIKELY CAUSED THE DAMAGE.  THE TORQUE TUBE ASSY WAS REPLACED AND THE ACFT RETURNED INTO SERVICE.
