Release the FLT CTL/ELAC 2 pushbutton switch (on this pushbutton switch, the OFF legend comes on).
The FLT CTL/ELAC 1 pushbutton switch is pushed (on this pushbutton switch, the OFF and FAULT legend are off).

(2) If the position of the elevator has changed, do as follows:
(a) Cut and remove the lockwire from the lock nut (2).
(b) Loosen the lock nut (2).
(c) Move the lock washers (3) apart.
(d) Turn the rod (4) until the trailing edge of the elevator is aligned with the reference triangle.
(e) TORQUE the lock nut (2) to between 3.5 and 3 m.daN (25.81 and 22.12 lbf.ft )

. Do not safety the lock nut (2) at this time.
(f) Make sure that the adjustment does not change when you TORQUE the lock nut.

(3) Make sure that you can easily engage and disengage the rigging pin into the elevator position transducer unit (1).
