R R R R A. This warning is shown after the failure of the four elevator servocontrols. To do the trouble shooting refer to the POST FLIGHT REPORT and start the trouble shooting from the first F/CTL ELEV SERVO FAULT warning and its related maintenance message. After this step, on the upper ECAM DU the F/CTL L ELEV FAULT or F/CTL R ELEV FAULT warning will go out of view and be replaced by F/CTL L ELEV FAULT and F/CTL ELEV SERVO FAULT or F/CTL R ELEV FAULT and F/CTL ELEV SERVO FAULT warning with a related maintenance message. Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001), to know the related maintenance message. Do the trouble shooting procedure related to this message.

A. If the message TEST NOT POSSIBLE is shown related to the normal engagement codes (03FF):
- the right (left) elevator damping test consists of 3 sequences as follows: (Ref. Fig. 201/TASK 27-30-00-991-001)

(1) If the test stops during the first sequence (the 2 servocontrols are controlled by the SEC1 and SEC2):
(a) Do an elevator operational test as follows:
- make sure that the Green, Blue and Yellow hydraulic systems are pressurized
- make sure that the SEC1 is engaged (the ELAC1 is disengaged)
- disengage the SEC2 (the ELAC2 is disengaged).
(b) Do an elevator operational test as follows:
- make sure that the Green, Blue and Yellow hydraulic systems are pressurized
- make sure that the SEC2 is engaged (the ELAC2 is disengaged)
- disengage the SEC1 (the ELAC1 is disengaged).
1_ Quickly move a side stick (CAPT or F/O) in full nose up then
in full nose down position:
- on the lower ECAM DU, the two elevator indexes move at the
same time with the same travel speed.
2_ If the left elevator does not move or if the travel speed is
