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, after the check, you think that the TPS layer is in the correct condition, you can apply a new layer as a spray on the existing layer.

(2) Put PAPER - MASKING or Adhesive Film Tape-Masking - - (Material No.05RDA1) on the equipment and fittings adjacent to the area.
(3) 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) OR Corrosion Preventive Compound-Water Displacing Hard Film - (Material No.12ABB1) on the inspection area (Ref. AMM TASK 51-78-00-916-001).
(4) If, before the inspection, there was:

Removal of the TPS layer or
Cleaning of the inspection area with high-pressure water, steam, solvents and/or cleaning agents

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).
