## Discrepancy

(CAN) DURING ANALYSIS OF THE FAULT HISTORY DATABASE FILE, TECH ADVISED THAT THERE WERE SEVERAL INTERMITTENT FAULTS WITH THE CPCS, CABIN PRESSURIZATION AND COMFORT SYSTEM.  DIAGNOSTIC TESTING UTILIZING THE CMC PROGRAM REVEALED THE PRESSURE CONTROLLER TO BE AT FAULT.  UNIT WAS REPLACED WITH SERVICEABLE UNIT, NO FURTHER FAULTS WERE OBSERVED.  PRIOR TO ADVISEMENT FROM MFG, SYSTEM WAS REPORTED TO FUNCTION NORMALLY WITH NO FAULTS.
