Subtask 57-21-00-916-053-A

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 Hard Film - (Material No.12ABB1) or a layer of Corrosion Preventive Compound-Heavy Duty Hard Film - (Material No.12ACB1) (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 Hard Film - (Material No.12ABB1) or a layer of Corrosion Preventive Compound-Heavy Duty Hard Film - (Material No.12ACB1) (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.
