(b) Temporarily install the control rod (7) with the bolt (11), the sliding bush (5), the washer (4) and the nut (3).
(3) Temporarily install the top cover (1) with some of the screws (2).
(4) Make sure that:

the flap track No. 3 movable fairing is correctly adjusted (Ref. AMM TASK 57-55-11-400-001)
the flap track No. 4 movable fairing is correctly adjusted (Ref. AMM TASK 57-55-11-400-001).

(5) Remove the screws (2) and the top cover (1).
(6) Hold the movable fairing and remove the nut (3), the washer (4), the sliding bush (5) and the bolt (11).
(7) Use a Textile-Lint free Cotton - (Material No.14SBA1) , made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) to clean the interfaces of:

the bolt (11) and the sliding bush (5)
the flap drive lever and the control rod (7).

(8) Apply a thin layer of Polysulfide Sealant-Low Adhesion Brushable - (Material No.06AEA1) or Polysulfide Sealant-Low Adhesion Fillet Structure (Material No.06AEB2) to the interfaces of the sliding bush (5) and the bolt (11), but not to the threads.
(9) Align the control rod (7) with the flap drive lever and install the bolt (11), the sliding bush (5), the washer (4) and the nut (3).
(10) TORQUE the nut (3) to between 1.0 and 0.9 m.daN (88.50 and 79.65 lbf.in )

.
(11) Safety the nut (3):

for the flap track No. 3 movable-fairing, with a new AIPC 57-55-05-04-020 COTTER PIN (6) or AIPC 57-55-85-04-160 COTTER PIN (6).
for the flap track No. 4 movable-fairing, with a new AIPC 57-55-05-06-020 COTTER PIN (6) or AIPC 57-55-85-06-160 COTTER PIN (6).

(12) Use a Textile-Lint free Cotton - (Material No.14SBA1) , made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) to clean the interfaces of the cover (1) and the screws (2).
(13) Install the end of the bonding strap (8) with the washer (10) and the bolt (9) (Ref. AMM TASK 20-28-00-912-802).
(14) Apply a thin layer of Polysulfide Sealant-Low Adhesion Brushable - (Material No.06AEA1) or Polysulfide Sealant-Low Adhesion Fillet Structure (Material No.06AEB2) and Release Agent-- Water Base - (Material No.14DAB1) to the interfaces of the cover (1).
(15) Apply a thin layer of Non Hardening Jointing Putty-Medium Temp. Area - - (Material No.06LCG9) to the screws (2).
(16) Install the top cover (1) with the screws (2).
(17) Apply a bead of Polysulfide Sealant-General Purpose Fillet - (Material No.06AAB1) into the groove between the cover (1) and the movable fairing.
