R  A. Deactivation of the Damaged Fairing 
R  (1) Remove the applicable damaged fairing (Ref. TASK 57-55-11-000-004). 
R  (2) For the track 2 position only, attach the electrical harnesses to 
R  aircraft structure as follows: 
R  CAUTION : DO NOT TIGHTEN THE CABLE TIE THAT IS USED AS A GUIDE FOR_______ 
R  THE ELECTRICAL HARNESSES. 
R  IF THE TIE IS TOO TIGHT, THE HARNESSES CANNOT MOVE WHEN THE 
R  FLAPS ARE EXTENDED OR RETRACTED. 
R  (a) Examine the electrical harnesses (9) for correct condition. 
R  (b) Attach the electrical harnesses (9) together at distances of 150 
R  mm (6.0 in.) to 200 mm (8.0 in.) with the cable ties (3). 
R  (c) Connect the electrical harnesses (9) to the interface connectors 
R  (6) then: 
R  - put the electrical harnesses (9) in position along the flap 
R  drive-arm (7) and the fairing drive-lever (4) 
R  - put the interface connectors (6) in the aft recess of the flap 
R  drive-arm (7). 
R  (d) Install the cable ties (3) to loosely hold the interface 
R  connectors (6) and the electrical harnesses (9). Put the cable 
R  ties (3) at distances of between 25 mm (0.9842 in.) and 50 mm 
R  (1.9685 in.) at: 
R  - the fairing drive-lever (4) 
R  - the flap link-arm (8) 
R  - the flap drive-lever (7). 
R  (e) Attach the electrical harnesses (3) at point 'Y' with the two 
R  cable ties (3). 
R  (f) Attach the electrical harnessses (9) to the flap drive lever (7) 
R  at point 'X' with the two cable ties (3). 
R  (g) Make the loops, at point 'Z', of the electrical harnesses (9) 
R  that are to pass through point 'X'. Make the loops in the correct
