Material of component

The HP compressor inlet guide vane is manufactured from titanium alloy.

General

This repair must only be done when the instruction to do so is given in 72-41-32 Inspection/Check.

This repair gives the instruction to remove damage on the HP compressor variable inlet guide vane by material removal.

If the minimum chord width is reached, then the vanes must be marked with the applicable code symbol.

Not more than ten percent of variable inlet guide vanes dressed to the maximum limit of this repair, marked with the applicable code symbol, should be included in any one vane stage.

Variable inlet guide vanes must be repaired as soon as damage or wear is monitored, to get back HP compressor efficiency and extend the vane life.

Material removal from the HP compressor variable inlet guide vane airfoil fillet radius is not permitted.

The practices and processes referred to in the procedure by the TASK/SUBTASK numbers are in the SPM.
