4. Procedure
Subtask 27-44-56-910-052-A
A. Preparation for the Installation
   (1) Make sure that the interface of the THS actuator (1) is clean and has no corrosion and shows no damage.
   (2) Make sure that the parts retained from the removed component are clean and in the correct condition.
   (3) Make sure that all the electrical connections are clean and in the correct condition.
   (4) Clean the interface of the THS actuator (1) and the position transducer (2) with the Non Aqueous Cleaner-- Petroleum Based - (Material No.08BBB1) and let it dry.
   (5) Make sure that the AIPC 27-44-56-01-020 PACKING (9) is in the correct condition. If necessary, replace the packing.

B. Installation of the Position Transducer
NOTE: The installation of the Command (COM) position transducer and the installation of the Monitor (MON) position transducer are the same. The installation procedure for one of the position transducers only is given.
   (1) Put the position transducer (2) in position at the THS actuator (1).
   (2) Hold the position transducer (2) in position at the THS actuator (1) and attach it with the screws (7) and the washers (8).
   (3) TORQUE the screws (7) to between 0.94 and 0.76 m.daN (83.19 and 67.26 lbf.in ) T.
   (4) Safety the screws (7) with lockwire 0.6 mm (0.0236 in.) 14QEB1Wire-Locking Dia: 0.6 mm CRES Nickel Alloy -.
   (5) Remove the blanking caps and connect the electrical connectors (3), (4) to the receptacles (5), (6).

C. Preparation for the Test
   (1) Make sure that the THS actuator 9CE has the correct quantity of oil (Ref. AMM TASK 27-44-51-210-004).
   (2) Remove the rigging pin OU 190360 from the mechanical input of the THS actuator 9CE.
   (3) Make sure that the travel range of the THS actuator 9CE and the travel range of the control surfaces are free.
