B. Aircraft Maintenance Configuration
(1)
Make sure that the aircraft electrical circuits are de-energized (Ref. TASK 24-41-00-862-002).
(2)
Make sure that the air conditioning is de-energized (Ref. TASK 12-33-21-618-001).
(3)
The aircraft must stay at least three hours in this configuration in order to get an uniform stabilized temperature.
(4)
The ambiant temperature must be within the range of 0 deg.C (32.00 deg.F), 40 deg.C (104.00 deg.F).
(5)
The cable routing area must not be lighten by neon located close the cable itself.
4. Procedure
_________
(Ref. Fig. 602/TASK 27-41-00-991-007) Subtask 27-41-00-220-050
A. Check of the Cable Tension Regulator of the THS Trim Control (Pointer in the Limits)
(1)
Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
(2)
Pressurize the Green and Yellow hydraulic systems (Ref. TASK 29-23-00-863-001) and (Ref. TASK 29-24-00-863-001).
(3)
Operate the THS more than ten times and put it in the zero position.
(4)
Install the PIN - RIGGING (0U190360) (1) on the input shaft of the THS actuator.

(5)
Depressurize the Green and Yellow hydraulic systems (Ref. TASK 29-23-00-864-001).
(6)
De-energize the aircraft electrical circuit (Ref. TASK 24-41-00-862-002).
(7)
Put a warning notice on the pitch-trim control wheels to tell persons not to use the pitch trim.
(8)
Bend the two cables to the same value and release them quickly. When you release the cables, make sure that the movable pulley bracket of the tension regulator moves easily (it must not be caught).
(9)
Measure the ambient temperature with a thermometer.
(10)
Use the adjustment graph to find the position of the index in relation to the measured ambient temperature. (Ref. Fig. 603/TASK 27-41-00-991-009)
(11)
Make sure that the position of the index agrees with the value found on the graph with a tolerance of + or - 1 graduation (+ or - 5 deg C).
(12)
If the result of the check is no correct, adjust the THS cable length (Ref. TASK 27-41-00-820-002).
5. Close-up
________ Subtask 27-41-00-860-059
A. Put the aircraft back to its initial configuration.
(1) Remove the PIN - RIGGING (0U190360).
(2) Remove the warning notice. Subtask 27-41-00-410-051
B. Close Access
(1)
Close the access doors 312AR, 824, 825, 826, 811, 812 (Ref. TASK 52-41-00-410-002).
(2)
Remove the access platform(s).
(3)
Make sure that the work area is clean and clear of tool(s) and other items.
