Subtask 53-21-00-916-073-A ** ON A/C NOT FOR ALL
B. Check and Application of the TPS Layer
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 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.
