## Discrepancy

(CAN) DURING MAINTENANCE CHECK, A CRACK WAS FOUND ON THE AFT END FLANGE OF THE ADAPTER. THE ADAPTER WAS REPLACED IAW RD6-57-266 BUT IT WAS FOUND THAT THE LOCK FASTENER COULD NOT BE INSTALLED AT 1 LOCATION DUE TO INTERFERENCE WITH INTERNAL STRUCTURE. OTHER FASTENER PROBLEMS THEN AROSE. A REPAIR SCHEME IS BEING PREPARED TO SOLVE THE FASTENER PROBLEM.
