## Discrepancy

FLT 4563 - DURING FINAL APPROACH INTO XNA FROM ATL, THE CREW SELECTED THE FLAPS TO FIRTY FIVE DEGREES FROM THIRTY AND RECEIVED A FLAPS FAIL MESSAGE.  THE AIRCRAFT PERFORMED A GO AROUND AND COMPLIED WITH THE QRH.  AN EMERGENCY WAS DECLARED AND THE AIRCRAFT LANDED SAFELY IN XNA.  MAINTENANCE REMOVED AND REPLACED THE BRAKE POSITION SENSOR UNIT, BPSU, AND THE POWER DRIVE UNIT.  MAINTENANCE ALSO PERFORMED A TORQUE CHECK OF THE ACTUATORS.  NO DEFECTS WERE NOTED.  OPERATIONAL CHECKS GOOD.  AIRCRAFT OK FOR SERVICE.  (M)
