A. Visual Inspection of the Aft-Pylon Fairing when there is a Coloration Condition

Aft-Pylon Fairing Coloration

(1) Do a visual inspection of the aft pylon fairing for coloration.
(2) If there is metal coloration because of black particles:
(a) Clean the inspection area with Non Aqueous Cleaner-General - - (Material No.08BAA9) and the Textile-Lint free Cotton - (Material No.14SBA1) .
(b) If necessary, use SCOTCHBRITE to remove all the black particles.

NOTE: The only function of this inspection task is to make the aft pylon fairing visually better. Thus, you can do the cleaning of the black particles during the next maintenance procedure.

(3) If there is metal coloration because of iridescence, only a mechanical rework can be satisfactory to remove this coloration. As this condition occurs regularly, Airbus does not recommend to remove it.
