1. On the panel 23VU:
- release the FLT CTL/ELAC 1 and the FLT CTL/SEC 1 pushbutton switches.
2. On the panel 24VU:
- release the FLT CTL/ELAC 2 and FLT CTL/SEC 2 pushbutton switches.
3. On the center pedestal:
R R R - make sure that the pitch trim-control wheel is in the zero position.
4. Depressurize the Green and Yellow hydraulic systems. (Ref. TASK 29-23-00-864-001).
R R 5. On the RH control-valve block (3) of the THS actuator (4):
R R R R R - install the TOOL - JAMMING SIMULATION RH A/C N.UP (OU190857) on the shaft (7) of the RH control- valve block. (Ref. Fig. 502/TASK 27-44-00-991-003)
R R R R R R R R R R R - push the TOOL - JAMMING SIMULATION on the splined end of the shaft (7) of the RH control-valve. - turn the mechanical input shaft (1) to turn the master spline, until the spigots of the tool engage with the slots of the valve block (3). - fully push the tool to insert the spigots in the slots.
On the panel 23VU:
-
the OFF legends of the FLT CTL/ELAC 1and FLT CTL/SEC 1 pushbutton switchescome on.
On the panel 24VU:
-
the OFF legends of the FLT CTL/ELAC 2and the FLT CTL/SEC 2 pushbuttonswitches come on.
On the THS actuator (4):
-the control-valve chain is in the jamming simulation configuration.

R (Ref. Fig. 502/TASK 27-44-00-991-003)
R R 6. On the THS actuator (4):
R R R - move the mechanical input shaft (1) in a Counter Clockwise (CCW) direction.
R R R 7. Pressurize the Green and the Yellow hydraulic systems (Ref. TASK 29-23-00-863-001). CAUTION : STOP THE PITCH TRIM_______ CONTROL WHEEL WITH YOUR HANDS IF THE THS-ACTUATOR DOES NOT STOP APPROXIMATELY 5 SECONDS AFTER YOU HAVE PUSHED THE FLT CLT / ELAC 2 PUSH BUTTON SWITCH. THIS OPERATES THE JAMMING PROTECTION DEVICE WHICH PREVENTS DAMAGE TO THE STOP OF THE MECHANICAL INPUT SHAFT.
8. On the center pedestal and on the panel 24VU:
R R R - look at the pointer of the pitch trim-control wheel. In the 5 degree nose UP position push the FLT CTL/ELAC 2 pushbutton switch.
On the control-valves of the THS actuator:
-
the control-valves are in the open position.
On the center pedestal:
-
the pitch trim-control wheel moves to the aircraft nose UP position (the THS leading edge moves down).
On the THS actuator (4) and on thepanel 24VU:
-the THS actuator stops (after
approximately 5 seconds), - on the upper ECAM DU:
-the ELAC 2 PITCH FAULT message
comes on,
-the OFF legend of the FLT CTL/ELAC 2 goes off.
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
R - if the THS actuator does not stop, do
R the operational test of the
R THS-actuator electrical control
R (Ref. TASK 27-96-00-710-022) and do
R the necessary corrective action.
R
9. On the panel 24VU: On the panel 24VU:
- release the FLT CTL/ELAC 2 - the OFF legend of the FLT CTL/ELAC 2
switch. switch comes on,
- on the upper ECAM DU:
- the ELAC 2 PITCH FAULT message goes
off.
10. Depressurize the Green and
Yellow hydraulic systems.
(Ref. TASK 29-23-00-864-001).
11. On the rudder pedals:
R - operate the rudder pedals in - all remaining pressure in the valve
R the left and right directions blocks of the THS actuator is
R and wait 1 minute. released.
R 12. On the THS actuator (4): On the RH threshold-box assy:
(Ref. Fig. 503/TASK 27-44-00-991-004)
R - turn the mechanical input (1) - the control-valve detent of the
R in the CCW direction. "JAMMED" control-valve becomes
R recentered (which was possibly opened
by the ELAC 2 ground setting command)
when you hear a "CLICK".
