## Discrepancy

(CAN) WHILE THE ACFT WAS IN A CRUISE CONFIGURATION, THE FLIGHT CREW EXPERIENCED A MOMENTARY LOSS OF THE PILOTS AND CO-PILOTS PRIMARY FLIGHT DISPLAYS, PFD IN ADDITION TO THE LOSS OF THE LOWER MULTI-FUNCTION FLIGHT DISPLAY, MFD.  AFTER A MOMENTARY LOSS OF APPROXIMATELY 3 TO 5 SECONDS OF THE PILOT`S AND THE CO-PILOT`S PRIMARY FLIGHT DISPLAYS AS WELL AS THE LOWER MFD DISPLAY, THE SCREENS REBOOTED AND RETURNED TO NORMAL OPERATION. THIS ACFT WAS BEING FERRIED TO A MAINTENANCE BASE WITH THE NR 1 AGM MODULE INOPERATIVE.  THE APEX AVIONICS SYS WAS BEING OPERATED IN THE REVERSIONARY MODE WHERE THE #2 AGM CARD WAS OPERATING THE PILOT`S PFD AND THE CO-PILOT`S PFD AS WELL AS THE LOWER MFD. ACFT MFG IS CURRENTLY INVESTIGATING THIS OCCURRENCE WITH THE AVIONIC SYSTEM MFG AND THE AIRCRAFT OPERATOR.
