REVERSE THRUST LEVER INTERLOCK ACTUATOR - REMOVAL/INSTALLATION
______________________________________________________________
1. General
_______
A. The reverse thrust lever interlock actuator is referred to as the interlock actuator in this procedure. This procedure has two tasks. The first task gives instructions to remove the interlock actuator. The second task gives instructions to install the interlock actuator.
B. The interlock actuator is a linear type actuator. It has a dc motor, which is part of it, to supply movement. It also has mechanical stops and limit switches to prevent movement that is more than the limit.
C. The interlock actuator uses approximately one second to extend or retract. In the retract position, the interlock actuator does not permit the reverser thrust lever to move until the two reverser sleeves have extended to approximately 60% of their full deployment. When the thrust reverser sleeves are at approximately 60% deployment, the EEC completes the electrical circuit to the interlock relay. The interlock relay will engerize, which will extend the interlock actuator. When the interlock actuator extends, the lock will be removed and the reverse thrust levers can move freely to the high power, reverse thrust position.
D. If you install a new interlock actuator, you must do the interlock actuator adjustment procedure (Ref 78-34-03/501).
