A. Inspection
(1) Do a detailed inspection of:

The internal structure
The inner skin
The vertical curved members
The longerons of the passenger/crew door for damage or discontinuities.

(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 types, classification and corrective action.

B. Check and Application of the TPS Layer

CAUTION: DO NOT APPLY TEMPORARY PROTECTION SYSTEM (TPS) TYPE 3 ON THE MOVABLE COMPONENTS. USE ONLY TPS TYPE 1 GRADE 2. IF YOU DO NOT OBEY THIS INSTRUCTION, THE MECHANISMS WILL NOT OPERATE CORRECTLY.

(1) If the TPS was removed at the "Preparation of the Inspection Area", apply a new layer of Corrosion Preventive Compound-Water Displacing & Heavy Duty Hard Film - (Material No.12ADB1) (Ref. AMM TASK 51-78-00-916-001).
(2) If the TPS was not removed at the "Preparation of the Inspection Area", do a check of the condition and integrity of the TPS layer (Ref. AMM TASK 51-78-00-916-001).
(3) If the TPS layer has local damage, remove the damaged TPS layer and apply a new layer of Corrosion Preventive Compound-Water Displacing & Heavy Duty Hard Film - (Material No.12ADB1) (Ref. AMM TASK 51-78-00-916-001).

NOTE: If, after the check of the condition and integrity, the TPS layer is in the correct condition, Airbus recommends that you apply a new layer as a spray on the existing layer. This is to make sure that the TPS layer continues to give satisfactory corrosion protection.
