C. Application of Temporary Protection System (TPS)
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 there is a TPS layer, do a check of the condition and integrity of the TPS layer (Ref. AMM TASK 51-78-00-916-001):
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 remaining layer.
   (2) If the TPS layer has local damage, remove the damaged TPS layer (Ref. AMM TASK 51-78-00-916-001) and apply a new layer of Corrosion Preventive Compound-Water Displacing & Heavy Duty Hard Film - (Material No.12ADB1) :
   (3) If, before the inspection, there was:
