SUBSTANCE: to enhance the reliability of operation of the actuator assembly within a wide temperature range (+-50 C), shields are installed in the actuator assembly in the housing in the area of the grooves for exit of the control surfaces folded inside the housing. A groove is made on the shields around the edges to receive a sealing collar. In the front part the shield is fastened to the housing by means of a breakable screw.
