Hopefully someone with knowledge of the system can comment on this.
The lever has three attachment points. The far end is where the control rod from the pedals connects. In the middle is the linkage that operates the pilot valve that then moves the servo. The end that is being inspected is connected to the servo itself. When this moves it resets the pilot valve to stop servo movement.
Standard method of controlling servos.
