CAUTION: BEFORE YOU INSTALL THE SCREWS ON THE PANEL, MAKE SURE THAT THE POSITION OF THE SCREWS IS CORRECT. AN INCORRECT POSITION OF THE SCREWS CAN CAUSE DAMAGE TO THE EQUIPMENT BELOW THE PANEL.
A. Installation of the Aft Cargo-Compartment Floor-Panels
NOTE: This procedure is applicable to all the aft cargo-compartment floor-panels (1).
   (1) Do an inspection of the component interfaces and the adjacent area.
   (2) Replace the damaged cords (4) with new cords.
   (3) Do a visual inspection of the aft cargo-compartment floor-panels (1) (Ref. AMM TASK 25-50-00-200-002).
   (4) Make sure that the adhesive tape (13) is in the correct condition.
   (5) If necessary, replace the damaged Sealing Profile-- PTFE Expanded - (Material No.14JAD1) (13):
     (a) Make sure that you apply the Sealing Profile-- PTFE Expanded - (Material No.14JAD1) (13) on the full width of the beams. If necessary, use more than one adhesive tape (13) on the same width.
NOTE: An overlap of maximum three layers of adhesive tape (13) is permitted.
     (b) Make sure that the overlap A between the adhesive tapes (13) is 10 -5 mm or +5 mm (0.394 -0.197 in. or +0.197 in.).
     (c) Make sure that the overlap B between the adhesive tapes (13) is 5 -2 mm or +5 mm (0.197 -0.079 in. or +0.197 in.).
     (d) Make sure that the overlap C between the adhesive tapes (13) is 5 -1 mm or +1 mm (0.197 -0.039 in. or +0.039 in.).
     (e) Make sure that the wider adhesive tape (13) is on top of the smaller adhesive tape (13).
     (f) Make sure that there is a protrusion of minimum 2 mm (0.079 in.) of adhesive tape (13) along the rail edges.
     (g) Make sure that the adhesive tape (13) is flush with the plugs.
     (h) If necessary, cut the adhesive tape (13):
       1 Make sure that there is a protrusion of minimum 2 mm (0.079 in.) of adhesive tape (13) to avoid damage on the structure protection.
     (i) Apply the Corrosion Preventive Compound-Heavy Duty Hard Film - (Material No.12ACB1) on the area without tape.
     (j) Make sure that the holes are clear. If not, use the plastic mandrel to remove the blockage.
   (6) For each aft cargo-compartment floor-panel (1) which has adhesive tapes (12) that are not in the correct condition:
     (a) Remove the adhesive tapes (12) from the aft cargo-compartment floor-panel (1).
     (b) Discard the adhesive tapes (12).
     (c) Clean the areas from which you removed the adhesive tapes (12) with the Non Aqueous Cleaner-General - - (Material No.08BAA9) and the Textile-Lint free Cotton - (Material No.14SBA1) .
     (d) Apply the new Sealing Profile-Seat Rail Self Adhesive - I shape (Material No.14JMB1) (12) on the aft cargo-compartment floor-panel (1).
NOTE: The removal of the Sealing Profile-Seat Rail Self Adhesive - I shape (Material No.14JMB1) is easy.
NOTE: Airbus recommends that you use the same adhesive tape for all the aft cargo-compartment floor-panels (1).
   (7) Make sure that you removed the peel ply from the aft cargo-compartment floor-panels (1) before the installation.
   (8) Make sure that the parts retained from the removed component are clean and in the correct condition.
   (9) Put the aft cargo-compartment floor-panels (1) and, if necessary, the seals (6), (7), (8) and (9) in position as follows:
     (a) Clean the seals (6), (7), (8) and (9) to remove the dust and the dirt before the installation.
     (b) Make sure that the seals (6), (7), (8) and (9) are in the correct condition.
     (c) If they are not, replace the seals (6), (7), (8) and (9). For this, refer to the identification marks made during the removal procedure.
     (d) Make sure that the seals (6), (7), (8) and (9) are flush with the surfaces of the adjacent aft cargo-compartment floor-panels (1).
   (10) Apply the Polysulfide Sealant-General Purpose Interfay - (Material No.06AAC1) in the holes at the end of each seal to a minimum distance of 40 mm (1.5748 in.) from the edge of the seal.
