## Discrepancy

THE FLIGHT CREW REPORTED THAT THE LEFT THRUST REVERSER DID NOT DEPLOY UPON LANDING - THE ARM ANNUNCIATOR ILLUMINATED. THE MAINTENANCE STAFF TROUBLESHOT AND DETERMINED THE LEFT CONTROL VALVE WAS AT FAULT. THE CONTROL VALVE WAS REMOVED AND A SERVICEABLE VALVE WAS INSTALLED. OPS CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
