B. Check and Application of the TPS Layer

CAUTION: DO NOT APPLY TEMPORARY PROTECTION ON THE OXYGEN SYSTEMS. MAKE SURE THAT THE TEMPORARY PROTECTION DOES NOT GET:

ON COMPOSITE PARTS, CONTROL CABLES, PULLEYS,TEFLON BEARINGS.
ON LUBRICATED SURFACES.
IN DRAIN VALVES OR OTHER ORIFICES.

TEMPORARY PROTECTION ON OR IN THESE PARTS CAN CAUSE DAMAGE.

(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) or Corrosion Preventive Compound-Water Displacing Hard Film - (Material No.12ABB1) (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 Soft Film - (Material No.12ABC1) or Corrosion Preventive Compound-Water Displacing Hard Film - (Material No.12ABB1) (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.
