A. Cleaning Procedure
(1) Make sure that the area for inspection is clean. If the inspection area is not clean:
(a) Clean the area with Non Aqueous Cleaner-General - - (Material No.08BAA9) and a Textile-Lint free Cotton - (Material No.14SBA1) .
(2) If there is a Temporary Protection System (TPS) layer applied that prevents the inspection of the area, remove the TPS layer (Ref. AMM TASK 51-78-00-916-001).
Subtask 52-31-11-210-062-A (1) Make sure that the area for inspection is clean. If the inspection area is not clean:
(a) Clean the area with Non Aqueous Cleaner-General - - (Material No.08BAA9) and a Textile-Lint free Cotton - (Material No.14SBA1) .
(2) If there is a Temporary Protection System (TPS) layer applied that prevents the inspection of the area, remove the TPS layer (Ref. AMM TASK 51-78-00-916-001).
B. Inspection
(1) Do a detailed inspection of the forward cargo-compartment door, hinge fittings and attachment area, external side, for damage or discontinuities. Do this on the top of the forward cargo-compartment door (inspection area "A").
(2) Make sure that there is no:
(a) Corrosion damage:
If you find corrosion, refer to the Structural Repair Manual ( SRM 512200) for the corrosion types, inspection, removal and subsequent corrosion protection.
(b) Other damage (scratches, cracks, gouges, dents, creases):
If you find this type of damage, refer to the Structural Repair Manual ( SRM 511100) for the damage classification and corrective action.
(3) Remove the actuator safety locks and close the cargo door to get access to inspection area "B" (Ref. AMM TASK 52-30-00-860-002).
(4) Do a detailed inspection of the forward cargo-compartment door, hinge fittings and attachment area, external side, for damage or discontinuities. Do this on the outer side of the forward cargo-compartment door (inspection area "B").
(5) Make sure that there is no:
(a) Corrosion damage:
If you find corrosion, refer to the Structural Repair Manual ( SRM 512200) for the corrosion types, inspection, removal and subsequent corrosion protection.
(b) Other damage (scratches, cracks, gouges, dents, creases):
If you find this type of damage, refer to the Structural Repair Manual ( SRM 511100) for the damage types, classification and corrective action.

C. Application of Temporary Protection System (TPS)
(1) Apply Adhesive Film Tape-Masking - - (Material No.05RDA1) on the items adjacent to the area: the seals, bellows, door mechanisms, proximity switches and fittings.
(2) If there is a TPS layer, do a check of the condition of the TPS layer (Ref. AMM TASK 51-78-00-916-001).
(4) If, before the inspection:
5. Close-up(1) Apply Adhesive Film Tape-Masking - - (Material No.05RDA1) on the items adjacent to the area: the seals, bellows, door mechanisms, proximity switches and fittings.
(2) If there is a TPS layer, do a check of the condition of the TPS layer (Ref. AMM TASK 51-78-00-916-001).
NOTE: AIRBUS recommends that you always apply a new layer of TPS. This is to make sure that the TPS layer continues to give satisfactory corrosion protection. If you think that the TPS layer is in the correct condition, you can apply a new layer (as a spray) on the layer.
(3) If the TPS layer is damaged, remove the TPS layer and apply a new layer of Corrosion Preventive Compound_Water Displacing Soft Film - (Material No.12ABC1) or Corrosion Preventive Compound-Water Displacing Hard Film - (Material No.12ABB1) . (4) If, before the inspection:
- there was removal of the TPS layer
or - the inspection area was cleaned with high pressure water, steam, solvents and/or cleaning agents.
