B. Detailed Inspection of the AFT Cargo Compartment Door, Internal Structure
(1) Examine the inner side of the outer skin, the edge members, the inner skin and the retainers (of the door seal) for subsequent damage.
(a) If you find a scratch:

determine the extent of the damaged area SRM 523000
remove the damage when it is less than the limit SRM 517300.

NOTE: When the scratch is larger than the limit, repair the effected component SRM 523000.

(b) If you find a dent:

find the limits of the damaged area SRM 523000
remove the damage when it is less than the limit SRM 527300.

NOTE: When the dent is larger than the limit, repair the effected component SRM 523000.

find the limits of the corroded area SRM 523000
remove the damage when it is less than the limit SRM 517400.

NOTE: When the corroded area is larger than the limit, repair the effected component SRM 523000.

(2) Examine the longitudinal beams, the door frames and the corner fittings of the cargo door (machined parts) for subsequent damage.
(a) If you find a scratch:

find the limits of the damaged area SRM 523000
remove the damage when it is less than the limit SRM 517300.

NOTE: When the scratch is outside the limit, repair the effected component SRM 523000.

(b) If you find a dent:

find the limit of the damaged area SRM 523000,
remove the damage when it is less than the limit SRM 527300.

NOTE: When the dent is outside the limit, repair the effected component SRM 523000.

find the limits of the corroded area SRM 523000

C. General Inspection of the Internal Structure of the Cargo Door
(1) Examine all rivets of the cargo door structure.
(a) If you find an empty rivet hole, install the rivet with correct sealant.
(b) If you find damaged or loose rivets, replace them.
(2) Examine the sealant of all structural components for the correct condition. If necessary, replace the sealant (Ref. AMM TASK 51-76-11-300-001).
(3) Make sure that all screws and bolts of the internal structure of the cargo door are correctly tightened and not damaged.
(4) Examine the water drain valves and drain holes of the cargo door to make sure that they are clean and free.
(5) Make sure that the paint coats of the structural components are in the correct condition (Ref. AMM TASK 51-75-12-300-001).

D. 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).

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.

(a) Apply a full new layer of Corrosion Preventive Compound_Water Displacing Soft Film - (Material No.12ABC1) or Corrosion Preventive Compound-Water Displacing Hard Film - (Material No.12ABB1) on the inspection area (Ref. AMM TASK 51-78-00-916-001).
