PART IDENT	MATERIAL
HP Compressor Stator Vanes, Stages 6 to 11	Heat Resisting Alloy

General

This TASK gives the procedure to glass/ceramic bead peen the HP Compressor Stator Vanes, Stage 6 to 11.

The vanes must have all other repairs completed and be serviceable, refer to relevant inspection procedures (identified by the applicable part number) located in section 72-41-22.

The vanes can only have the glass/ceramic bead peening operation completed on them three times.

This repair can be done again to the HP Compressor Stator Vanes if the part is within the repairable limits as given in vibro-polishing repairs (VRS6499, VRS6080, VRS6081, VRS6082, VRS6083 and VRS6084).

The practices and processes referred to in the procedure by the TASK/SUBTASK numbers are in the Standard Practices Manual (SPM).

Price and Availability.

Refer to International Aero Engines (IAE).
