## Discrepancy

FLIGHT 5980,  DURING CLIMB, FLIGHT CREW WAS UNABLE TO GET THE AC TO PRESSURIZE USING EITHER MANUAL OR AUTO PRESSURIZATION MODES. FLIGHT RETURNED TO DEPARTURE AND LANDED WITHOUT INCIDENT.

MANUAL PRESSURIZATION CONTROLLER WAS ALSO FOUND TO BE NOT CONTROLLING PRESSURIZATION AND IT WAS REPLACED. (A)
