## Discrepancy

AT FL360 THE CREW REPORTED THAT THEY LOST BOTH THE NR 1 & 2  CABIN CONTROLLERS.  CREW MADE AN EMERGENCY DESCENT AND REGAINED THE CABIN AT FL320 IN MANUAL CONTROL.  FLIGHT CONTINUED TO DESTINATION AND LANDED WITHOUT INCIDENT.  REPLACED CABIN PRESSURE SELECTOR PANEL AND NR 2 AC OUTFLOW VALVE MOTOR.  BITE TEST OF BOTH CONTROLLERS BITE NORMAL.
