## Discrepancy

THE FLIGHT CREW REPORTED THE VAPOR CYCLE AIR CONDITIONING INOPERATIVE. THE MAINTENANCE PROVIDER DETERMINED THAT THE SYSTEM CIRCUIT BREAKER WAS DEFECTIVE. THE MAINTENANCE PROVIDER REMOVED AND REPLACED THE CIRCUIT BREAKER. OPERATIONAL CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
