## Discrepancy

AFTER TAKEOFF, CREW RECEIVED MULTIPLE ECAM WARNINGS: ENGINE NR 1 BLEED LOW TEMP, APU AFT FUEL PUMP, PACK NR 2 AIR INLET FLAP ACTUATOR FAIL, PACK 2 INLET PRESSURE SENSOR AND NAC COOL VALVE FAILURE.  FLIGHT RETURNED TO PHL AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE RESET THE SDAC'S AND FWC'S AND PERFORMED AN ENGINE RUN.  THE BLEED AND PACK PROBLEMS DID NOT RETURN.  HOWEVER, THE PACK INLET PRESSURE SENSOR IS TARGETED FOR TROUBLESHOOTING.  THE APU AFT FUEL PUMP PROBLEM COULD NOT BE DUPLICATED.  MAINTENANCE REPLACED THE RIGHT TVBC AIR VALVE.  SUBSEQUENTLY, THE AFT FUEL PUMP AND THE RIGHT PACK INLET FLAP ACTUATOR WERE REPLACED.
