## Discrepancy

DURING APPROACH INTO AVL FROM ATL, THE CREW RECEIVED A FLAP UNLOCK MESSAGE WITH A MASTER WARNING.  A GO-AROUND WAS INITIATED AND THE CREW REQUESTED EMERGENCY EQUIPMENT AS A PRECAUTION.  A ZERO DEGREE FLAP LANDING WAS ACCOMPLISHED AND THE AIRCRAFT LANDED SAFELY IN AVL.  MAINTENANCE INSPECTED THE FLAPS, ACTUATORS, SPOILERS AND HYDRAULIC SYSTEM FOR LEAKS.  NO DEFECTS WERE NOTED.  OPS CHECKS GOOD.  AIRCRAFT OK FOR SERVICE.  (M)
