PROBLEM TO BE SOLVED: To provide an actuator assembly comprising a synchronized hydraulic actuator. SOLUTION: The actuator assembly comprises a master actuator 10 and at least one slave actuator 20 having a cylinder 200 containing a piston 202 defining two chambers in the cylinder. The first chamber of the slave actuator is connected to an outlet of a directional control valve 260 connected to a hydraulic control circuit 50, and to a control member whose position determines the pressure in the first chamber of the slave actuator. A displacement of the piston 102 of the master actuator 10 is transferred to the control member of the control valve 260 associated with the slave actuator, and a displacement of the piston 202 of the slave actuator 20 is servo-controlled to the displacement of the piston of the master actuator by controlling the position of the control member of the control valve associated with the slave actuator 20.
