## Discrepancy

SMF - FLIGHT 2438 - AIRCRAFT FAILED TO PRESSURIZE ON CLIMBOUT AND THE CREW RETURNED TO FIELD.  MAINTENANCE INSPECTED THE AIRCRAFT AND PLACED THE SYSTEM ON MEL. MAINTENANCE REPLACED THE SEAL ON THE AFT PASSENGER DOOR. OPERATIONAL CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
