A. Inspection
(1) Do a detailed visual inspection of the rudder hinge arm 1, 2, 3, 4 and 5 and the fin actuator fittings actuator 1, 2 and 3.
Subtask 55-30-00-916-050-A (1) Do a detailed visual inspection of the rudder hinge arm 1, 2, 3, 4 and 5 and the fin actuator fittings actuator 1, 2 and 3.
B. Application of the Temporary Protection System (TPS)
(2) 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).
(4) If the TPS is in the correct condition, apply a new layer as a spray on the remaining layer.
(5) Replace the damaged TPS layer with Corrosion Preventive Compound_Water Displacing Soft Film - (Material No.12ABC1) or Corrosion Preventive Compound-Water Displacing Hard Film - (Material No.12ABB1) on the applicable rudder hinge arm (Ref. AMM TASK 51-78-00-916-001).
(6) If you use solvents, high-pressure water, steam and/or cleaning agents to clean the TPS layer:
(a) Apply a full new layer of TPS on the inspection area (Ref. AMM TASK 51-78-00-916-001).
(b) If there is no TPS layer, apply a new layer of TPS on the inspection area (Ref. AMM TASK 51-78-00-916-001).

5. Close-upWARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
CAUTION:
DO NOT APPLY TEMPORARY PROTECTION ON THE OXYGEN SYSTEMS.
MAKE SURE THAT THE TEMPORARY PROTECTION DOES NOT GET:
(1) Apply Adhesive Film Tape-Masking - - (Material No.05RDA1) on the equipment and fittings adjacent to the area. - ON COMPOSITE PARTS, CONTROL CABLES, PULLEYS,TEFLON BEARINGS.
- ON LUBRICATED SURFACES.
- IN DRAIN VALVES OR OTHER ORIFICES.
(2) 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.
(3) Make sure that the TPS layer is in the correct condition after the check.(4) If the TPS is in the correct condition, apply a new layer as a spray on the remaining layer.
(5) Replace the damaged TPS layer with Corrosion Preventive Compound_Water Displacing Soft Film - (Material No.12ABC1) or Corrosion Preventive Compound-Water Displacing Hard Film - (Material No.12ABB1) on the applicable rudder hinge arm (Ref. AMM TASK 51-78-00-916-001).
(6) If you use solvents, high-pressure water, steam and/or cleaning agents to clean the TPS layer:
(a) Apply a full new layer of TPS on the inspection area (Ref. AMM TASK 51-78-00-916-001).
(b) If there is no TPS layer, apply a new layer of TPS on the inspection area (Ref. AMM TASK 51-78-00-916-001).
(7) Remove the masking paper or the masking tape.
