## Discrepancy

AFTER TAKEOFF FROM RJTY, THE AIRCRAFT WOULD NOT PRESSURIZE.  THE CREW RETURNED TO RJYT AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE AIRCRAFT AIR-CONDITIONING PACK SYSTEM AND PERFORMED AN OPERATIONAL CHECK OF THE AIRCRAFT PACK SYSTEM.  THE AIRCRAFT SUCCESSFULLY PRESSURIZED DURING THE OPERATIONAL CHECK AND THE AIRCRAFT WAS RETURNED TO SERVICE.
