## Discrepancy

(CAN) FUNCTIONAL CHECK OF THE HYD SHUT-OFF VALVES DETECTED A FAILURE OF THE NR 2 ENG FUEL SHUT-OFF VALVE STANDBY ACTUATOR. (THE 2 VALVES ARE WIRED IN SERIES.) THE INTERNAL SWITCH AND STANDBY MOTOR WINDINGS CIRCUIT SHOWS OPEN.  ACTUATOR WAS REPLACED AND FAULT CLEARED. THE STANDBY CIRCUIT OF THIS MOTOR IS ONLY TESTED DURING AN `A` PHASE INSP EVERY 400 HRS. OR 8 MONTHS. THIS FAILURE WOULD NOT BE EVIDENT TO THE FLIGHT CREW DURING NORMAL OPERATIONS.
