The elevator operates through push/pull rods, a bell crank and an actuator arm. The
actuator arm is part of the elevator. The push/pull rod that connects the actuator arm is
made of carbon fiber. The bell crank has a sealed ball bearing. For information on the bell
crank, refer to chapter 27-30-02.
The elevator is attached at six hinge points to the horizontal tail. The travel stops are in the
torque tube. Refer to Figure 27-3, position 15.
