## Discrepancy

CREW REPORTED "FAIL FLAP" CASS MESSAGE.  AFTER EXTENSIVE TROUBLESHOOTING FOR WHAT WAS PERCEIVED TO BE AN ELECTRICAL ISSUE FOUND THAT A SWAGGED SLEEVE ON THE NR 6 FLEX DRIVE ASSY, PN 9914344-38 (MFG PN 140527-38) HAD SLIPPED AT THE CRIMP.  THE MFG IPC REPLACES THIS PART WITH PN 9914344-56.  IT HAS BEEN LEARNED THAT THIS SAME PN HAS FAILED ON THIS MODEL IN THE PAST.  REPLACED NR 6 FLEX DRIVE AND COMPLETED MECHANICAL AND ELECTRICAL RIGGING.  ALL CHECKS OK.
