A. Safety Precautions
   (1) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.
   (2) Put a WARNING NOTICE(S) in position to tell persons not to operate the flap/slat controls.
WARNING: BEFORE YOU START WORK, YOU MUST PUT ON A SAFETY HARNESS AND ATTACH IT TO THE ACCESS PLATFORM. WITHOUT A SAFETY HARNESS, YOU CAN FALL. THIS CAN KILL YOU OR CAUSE YOU INJURY.
   (3) Put on and attach a 98L12003001000 HARNESS,SAFETY before you start work in the work area.

B. Aircraft Maintenance Configuration
WARNING: MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS SURFACES ARE CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
   (1) Extend the flaps to position 1 (Ref. AMM TASK 27-50-00-866-008).
   (2) Make sure that the 98D27803000000 LOCKING TOOL-FLAP SLAT LEVER,INT. POSITION is installed on the flap/slat control lever (Ref. AMM TASK 27-00-00-480-002).
   (3) Remove the lower kink seal, the cushion seals and the upper kink seals from the flaps (Ref. AMM TASK 27-54-61-000-002).
   (4) Put the ACCESS PLATFORM 2M (6 FT) - ADJUSTABLE is in position:
  • For the left wing, below zone 580
  • For the right wing, below zone 680.

4. Procedure
Subtask 27-51-44-210-058-A
A. Inspection
   (1) Do an inspection of the rod-end (4) and the locking device (located between the locknut (1) and the nut (2)), for wear or damage. Replace a worn or damaged rod-end, or a worn or damaged locking device (Ref. AMM TASK 27-51-44-960-001).
Subtask 27-51-44-820-053-B
B. Adjustment of the Interconnecting Strut
WARNING: USE PROTECTIVE GOGGLES AND GLOVES WHEN YOU REMOVE OR INSTALL LOCKWIRE. EACH TIME YOU CUT LOCKWIRE, REMOVE AND DISCARD IT IMMEDIATELY. LOOSE LOCKWIRE CAN CUT YOU OR MAKE YOU BLIND, AND/OR CAN CAUSE DAMAGE.
   (1) Install the 98D27504031000 PIN-SETTING in the inspection/setting hole of the interconnecting strut (3).
NOTE: The interconnecting strut (3) can have one or two inspection/setting holes. If there are two, use the hole that is not blocked by the aircraft structure.
   (2) If necessary, adjust the actuating rod of the interconnecting strut (3) until you can install the 98D27504031000 PIN-SETTING as follows:
     (a) If necessary, remove and discard the lockwire from the locknut (1).
     (b) Loosen the locknut (1) sufficiently to let you turn the nut (2).
     (c) Adjust the nut (2) until you can install the 98D27504031000 PIN-SETTING.
     (d) Make sure that you can see the threads of the rod-end (4) through the check hole.
     (e) If you cannot see the threads of the rod-end (4) through the check hole, do a check of the flap rigging (Ref. AMM TASK 27-51-00-820-003).
     (f) Torque the locknut (1) to between 5.9 and 5.1 m.daN (43.51 and 37.61 lbf.ft ) T.
     (g) Safety the locknut (1) with 14QFB1Wire-Locking Dia: 0.8 mm CRES Nickel Alloy -.
   (3) Remove the 98D27504031000 PIN-SETTING from the hole in the interconnecting strut (3).
