## Discrepancy

THE INBOARD ACTUATOR ATTACH RIB STIFFENER ON THE NR 8 SLAT ACTUATOR WAS FOUND CRACKED.  THE DAL MFG PART NUMBER FOR THE INBOARD AND OUTBOARD STIFFENERS IS (57-0367-002).  BOTH THE INBOARD AND OUTBOARD ATTACH RIB STIFFENERS WILL BE REPLACED PER EO 4-59271-3AD.  THIS ER/A DOES NOT PROVIDE TERMINATING ACTION FOR EO 4-59271-3AD.  OPERATIONS 570 AND 590 HAVE BEEN COMPLIED WITH FOR THE NR 8 SLAT ONLY.
