## Discrepancy

IAH - FLT 3584 - CREW REPORTED THAT A FORWARD SMOKE WARNING INDICATION ILLUMINATED DURING FLIGHT.  THE CREW DECLARED AN EMERGENCY AND LANDED AT IAH WITHOUT INCIDENT.  MAINTENANCE TROUBLESHOT THE AIRCRAFT AND FOUND THE WARNING TO BE A FALSE INDICATION.  MAINTENANCE THEN REMOVED AND REPLACED THE CENTRAL CREW ALERTING COMPUTER.  THE SYSTEM OPERATIONALLY CHECKED GOOD AND THE AIRCRAFT WAS APPROVED FOR RETURN SERVICE.
