## Discrepancy

ON CLIMBOUT, THE PRIMARY TRIM CONTROL AND BOTH YOKE SWITCHES WERE INOPERATIVE.  CREW RESET THE CIRCUIT BREAKERS AND CHECKED THE CUTOUT WITH NO HELP.  ALTERNATE TRIM VIA AUTOPILOT DID OPERATE NORMALLY.  FLIGHT RETURNED TO MSP WITHOUT INCIDENT.  MAINTENANCE FOUND THE PRIMARY TRIM ACTUATOR MOTOR LEAKING OIL.  REPLACED THE PRIMARY TRIM ACTUATOR MOTOR.  OPERATIONAL CHECK OK.
