## Discrepancy

IAH - FLIGHT 2520, THE CREW REPORTED ELECTRICAL RELAY CONTINUED TO CLICK, AFTER T/O IT SLOWED DOWN CLICKING BUT CONTINUED WHEN THE GEAR WAS LOWERED.  THE AIRCRAFT RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED RELAYS K0023 & K0455, OPERATIONALLY TESTED WITH NO DEFECTS, AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
