## Discrepancy

THE FLIGHT CREW REPORTED THE THRUST REVERSER AUDIO ANNUNCIATOR GIVING IMPROPER AUDIO WARNINGS EXAMPLE: STOW THRUST REVERSERS DURING NORMAL OPERATIONS AND NORMAL INDICATIONS. THE MAINTENANCE PROVIDER TROUBLESHOT AND DETERMINED THE RIGHT THRUST REVERSER CONTROL VALVE TO BE DEFECTIVE. THE DEFECTIVE CONTROL VALVE WAS REMOVED AND REPLACED WITH A SERVICEABLE UNIT. OPS CHECKS WERE SATISFACTORY, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
