What was found

DURING A PHASE 1, THROUGH 5 INSP, FOUND BROKEN STRANDS IN A FLAP CABLE, PN 5565150-3 FOR THE RT FLAP. AFTER INSTALLING THE NEW FLAP CABLE IT WAS DISCOVERED THAT THE CHOICE OF LOCKING PINS FOR THE TURNBUCKLE WERE TOO SHORT OR TOO LONG. FURTHER INVESTIGATION DISCOVERED THE TURNBUCKLE BARREL, PN MS21251B6S HAD BEEN MACHINED SHORTER AND LOCKING PINS CUT TO FIT. WE ARE CURRENTLY WORKING WITH MFG TO RESOLVE THIS ISSUE.
