Description
A. The Leading Edge Slat Actuator Assembly is a double acting hydraulic actuator used to position the
aircraft leading edge slat surfaces.
B. An outer piston assembly attaches to a transfer tube which contains the inner piston. A bearing retains
the outer piston in the housing assembly. A rod end with a visual locked position indicator is attached
to the inner piston.
C. A lock stud assembly, four lock segments, and a lock piston housed inside the inner piston form a lock
mechanism to prevent inadvertent extension of the actuator.
D. Hydraulic pressure is applied through the manifold and blocking valve assemblies, mounted to the
actuator housing.
