(5) Remove the PAPER - MASKING or the Adhesive Film Tape-Masking - - (Material No.05RDA1) .
5. Close-upCAUTION:
DO NOT APPLY TEMPORARY PROTECTION ON THE OXYGEN SYSTEMS.
MAKE SURE THAT THE TEMPORARY PROTECTION DOES NOT GET:
(1) If there is a TPS layer, do a check of the condition of the TPS layer (Ref. AMM TASK 51-78-00-916-001). - ON COMPOSITE PARTS, CONTROL CABLES, PULLEYS,TEFLON BEARINGS.
- ON LUBRICATED SURFACES.
- IN DRAIN VALVES OR OTHER ORIFICES.
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.
