General
This Repair must only be done when the instruction to do so is given in 72-41-34 Inspection.
This Repair has been issued for the HP compressor stage 6 actuating ring connector assembly surface damage.
The practices and processes referred to in the procedure by the TASK number are in the SPM.
The surface protection will normally only be replaced if the bushes need to be removed if worn or damaged. Otherwise a local touch-up will be used if the surface is damaged.
The new bushes will be fitted after the surface protection has been completed.
Any surface protection damaged during the replacement of the bushes will be touched-up locally.
