A. Get Access
(1) Put an ACCESS PLATFORM 3M (10 FT)- ADJUSTABLE at zone 123 (124) and/or 125 (126).
(2) Open the lateral avionics-compartment doors 812 ( 822) (Ref. AMM TASK 52-41-00-010-002).
(3) Remove the necessary insulation blankets between FR12 and FR15 to get access to the inspection areas (Ref. AMM TASK 25-80-00-000-001).
Subtask 53-11-00-110-110-A (1) Put an ACCESS PLATFORM 3M (10 FT)- ADJUSTABLE at zone 123 (124) and/or 125 (126).
(2) Open the lateral avionics-compartment doors 812 ( 822) (Ref. AMM TASK 52-41-00-010-002).
(3) Remove the necessary insulation blankets between FR12 and FR15 to get access to the inspection areas (Ref. AMM TASK 25-80-00-000-001).
B. Preparation of the Inspection Area
(1) Make sure that the inspection area is sufficiently clean to do a satisfactory inspection of the area.
(2) If it is not sufficiently clean, clean the inspection area with Non Aqueous Cleaner-General - - (Material No.08BAA9) and a Textile-Lint free Cotton - (Material No.14SBA1) .
(3) If there is a Temporary Protection System (TPS) layer and if it does not let you do a satisfactory inspection, remove the TPS layer (Ref. AMM TASK 51-78-00-916-001).
4. Procedure(1) Make sure that the inspection area is sufficiently clean to do a satisfactory inspection of the area.
(2) If it is not sufficiently clean, clean the inspection area with Non Aqueous Cleaner-General - - (Material No.08BAA9) and a Textile-Lint free Cotton - (Material No.14SBA1) .
(3) If there is a Temporary Protection System (TPS) layer and if it does not let you do a satisfactory inspection, remove the TPS layer (Ref. AMM TASK 51-78-00-916-001).

This inspection does not include the areas below the heat exchanger panels between structure FR12 to FR14.
(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.
- 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
(1) If the TPS was removed at the "Preparation of the Inspection Area", apply a new layer of Corrosion Preventive Compound_Water Displacing Soft Film - (Material No.12ABC1) (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).
If the TPS layer has local damage, remove the damaged TPS layer and apply a new layer of Corrosion Preventive Compound_Water Displacing Soft Film - (Material No.12ABC1) (Ref. AMM TASK 51-78-00-916-001).
5. Close-up(1) If the TPS was removed at the "Preparation of the Inspection Area", apply a new layer of Corrosion Preventive Compound_Water Displacing Soft Film - (Material No.12ABC1) (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).
If the TPS layer has local damage, remove the damaged TPS layer and apply a new layer of Corrosion Preventive Compound_Water Displacing Soft Film - (Material No.12ABC1) (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 given, satisfactory corrosion protection.
