4. Procedure
Subtask 57-55-00-040-052-B ** ON A/C NOT FOR ALL

A. Deactivation of the Flap-Track Fairing
(1) Remove the damaged flap-track fairing (Ref. AMM TASK 57-55-11-000-001).
(2) For the track 2 position:

CAUTION: DO NOT TIGHTEN THE CABLE TIE THAT IS USED AS A GUIDE FOR THE ELECTRICAL HARNESSES. IF THE TIE IS TOO TIGHT, THE HARNESSES CANNOT MOVE WHEN THE FLAPS ARE EXTENDED OR RETRACTED.

(a) Examine the electrical harnesses for correct condition.
(b) Install two layers of the conduit at position 1 ESPM 203333.
(c) Safety the conduits at distances of 100 mm (3.9370 in.) with the TIE WRAP(S).
(d) Apply TAPE - 3M CONDUCTIVE ELEC(X-1181-COPPER OR X-1170-ALU) or Adhesive Film Tape-- Aluminium Foil - (Material No.05RAB9) around the electrical conduits at position 2.
(e) Attach the electrical harnesses with a cable tie at position 3. Make sure that you do not fully tighten the cable tie.
(f) After each flight, you must examine the electrical harnesses and the interface connectors to make sure that:

There is no damage to the electrical harnesses.
There is no chafing of the electrical harnesses.
The interface connectors are correctly attached and are not damaged.

(3) After each flight, make sure that the lubrication of the deactivated flap-track assembly is satisfactory (Ref. AMM TASK 12-22-27-640-004).
(4) Make an entry in the aircraft log to tell that you deactivated the flap-track fairing.
