Subtask 53-22-14-916-053-A
A. Preparation for Installation
   (1) Remove the sealant from the forward cargo-compartment floor-panels (1) with the SCRAPER - NON METALLIC.
   (2) Clean the component interface and the adjacent area with Non Aqueous Cleaner-General - - (Material No.08BAA9) and the Textile-Lint free Cotton - (Material No.14SBA1) .
   (3) Make sure that the parts retained from the removed component are clean and in the correct condition.
   (4) Replace the damaged cords (3) with new cords.
   (5) Do an inspection of the component interfaces and the adjacent area.
   (6) Do a visual inspection of the forward cargo-compartment floor-panels (1) (Ref. AMM TASK 25-50-00-200-002).
   (7) Make sure that the adhesive tape (11) is in the correct condition.
   (8) If necessary, replace the damaged Sealing Profile-- PTFE Expanded - (Material No.14JAD1) (11):
     (a) Make sure that you apply the Sealing Profile-- PTFE Expanded - (Material No.14JAD1) (11) on the full width of the beams. If necessary use more than one adhesive tape (11) on the same width.
NOTE: An overlap of maximum three layers of adhesive tape (11) is permitted.
     (b) Make sure that the overlap A between the adhesive tapes (11) 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 (11) 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 (11) is 5 -1 mm or +1 mm (0.197 -0.039 in. or +0.039 in.).
     (e) Make sure that the wider adhesive tape (11) is on top of the smaller adhesive tape (11).
     (f) Make sure that there is a protrusion of minimum 2 mm (0.079 in.) of adhesive tape (11) along the rail edges.
     (g) Make sure that the adhesive tape (11) is flush with the plugs.
     (h) If necessary, cut the adhesive tape (11):
       1 Make sure that there is a protrusion of minimum 2 mm (0.079 in.) of adhesive tape (11) to avoid damage on the structure protection.
     (i) Apply 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.
   (9) For each forward cargo-compartment floor-panel (1) which has adhesive tapes (10) that are not in the correct condition:
     (a) Remove the adhesive tapes (10) from the forward cargo-compartment floor-panel (1).
     (b) Discard the adhesive tapes (10).
     (c) Clean the areas from which you removed the adhesive tapes (10) with 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) (10) on the forward 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 forward cargo-compartment floor-panels (1).
Subtask 53-22-14-420-054-A
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.
B. Installation of the Forward Cargo-Compartment Floor-Panels
NOTE: This procedure is applicable to all the forward cargo-compartment floor-panels (1).
   (1) Make sure that you removed the peel ply from the forward cargo-compartment floor-panels (1) before the installation.
   (2) Make sure that the work area is clean and clear of tools and other items.
   (3) Put the forward cargo-compartment floor-panels (1) and, if necessary, the seals (4), (5), (6) and (7) in position as follows:
     (a) Clean the seals (4), (5), (6) and (7) to remove the dust and the dirt before the installation.
     (b) Make sure that the seals (4), (5), (6) and (7) are in the correct condition.
     (c) If they are not, replace the seals (4), (5), (6) and (7). For this, refer to the identification marks made during the removal procedure.
     (d) Make sure that the seals (4), (5), (6) and (7) are flush with the surfaces of the adjacent forward cargo-compartment floor-panels (1).
   (4) Apply 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.
   (5) Make sure that all the seals are flush with each other.
   (6) Apply Non Hardening Jointing Putty-Medium Temp. Area - - (Material No.06LCG9) on the screws (2).
   (7) Install the screws (2) and, if applicable, the washers (8) and the nuts (9).
   (8) TORQUE the screws (2) to between 0.42 and 0.37 m.daN (37.17 and 32.74 lbf.in ) T.
NOTE: The minimum protrusion length of a screw is a half thread.
   (9) Make sure that the screws (2) are not too short. If they are, use the next available screw length.
   (10) If necessary, apply Polysulfide Sealant-General Purpose Fillet - (Material No.
06AAB1) on the nuts (9).
   (11) If necessary, let the sealant cure.
   (12) If necessary, apply one or more protective layer(s) of Coating-- Corrosion Inhibiting Fastener Head Protection (Material No.04QAC5) or Primer Polyurethane Paint_- Corrosion Inhibiting Structure (Material No.04EAC2) and Top Coat Polyurethane_- Grey Internal Structure (Material No.04JME4) on the heads of the screws (2).
   (13) Install the FIBER GLASS CORD 1.1 MM DIA. (DAN107-1) (3) between the forward cargo-compartment floor-panels (1).
   (14) Make a loop at the two ends of the cord (3).
NOTE: This will make the subsequent removal procedure easier.
   (15) Apply Polysulfide Sealant-General Purpose Interfay - (Material No.06AAC1) or Polysulfide Sealant-Gap Filler Easily Removed - - (Material No.06AHG1) between the forward cargo-compartment floor-panels (1), the cutouts and the tiedowns.
