## Discrepancy

MCI - FLT 201 - ENROUTE PHL - SFO, DURING CRUISE, ECAM MESSAGE F/CTL ELAC 2 PITCH FAULT GENERATED, FOLLOWED BY AN A/P 2 DISC MESSAGE.  AFTERWARDS, CREW FURTHER RECEIVED ECAM MESSAGES F/CTL STABILIZER JAM AND F/CTL ALTN LAW.  DURING THIS TIME, STATUS ITEMS THAT BECAME INOPERATIVE WERE: F/CTL ROT, STAB, ELAC PITCH, AND A/P 1 AND 2.  AT THIS TIME, THE FLIGHT CREW REPORTED DIFFICULTY IN CONTROLLING PITCH.  MANUAL TRIM WAS USED TO CONTROL PITCH.  FLIGHT CREW OBSERVED THAT CONTROLLABILTY IMPROVED AS THE AIRCRAFT DESCENDED.  MAINTENANCE REPLACED ELAC 2.  OPERATIONALLY CHECKS OK.
