Procedure

    1. SUBTASK 72-32-91-350-058 Remove the Damage from the LPC Inlet Guide Vane Assembly

    1. Refer to Figure, Figure and Figure.

      2. CAUTION

        TITANIUM COMPONENT - YOU MUST USE SILICON CARBIDE TYPE ABRASIVE WHEELS, STONES AND PAPERS TO DRESS, BLEND AND POLISH THIS COMPONENT. ALUMINUM OXIDE TYPE MUST NOT BE USED. IF MECHANICAL CUTTERS ARE USED, ONLY LIGHT CUTS MUST BE MADE TO AVOID OVERHEATING THE MATERIAL.

        CAUTION

        TITANIUM COMPONENT - AVOID BUILD UP OF HEAT BY APPLYING ONLY GENTLE PRESSURE AND KEEPING THE TOOL SPEED AS LOW AS POSSIBLE. USE TECHNIQUES WHICH ALLOW FOR PROGRESSIVE WEAR OF THE DRESSING MEDIA TO PRESENT A CONTINUALLY FRESH CUTTING SURFACE TO THE WORK PIECE.

        CAUTION

        DO NOT DWELL ON ONE AREA OF THE COMPONENT.

        CAUTION

        DRESS, WHERE POSSIBLE, IN A CIRCULAR MOTION; TAKING LIGHT CUTS TO AVOID OVERHEATING.

        CAUTION

        TITANIUM COMPONENT - YOU MUST MAKE SURE THAT WHEN YOU REMOVE MATERIAL, BLEND AND POLISH, TO MAKE SMOOTH, THAT NO SPARKS ARE PRODUCED AND THE ADJACENT AREA IS MASKED OFF.

        CAUTION

        TITANIUM COMPONENT - IF THE MATERIAL SHOWS A CHANGE IN COLOR DURING DRESSING, TO DARKER THAN A LIGHT STRAW COLOR, THE COMPONENT IS TO BE REJECTED.

        Scallop, make smooth and/or hand polish to remove nicks, dents, scores and/or galls.

        1. Use abrasive stones or abrasive papers and/or a fine file.

        2. Use light pressure to prevent the risk of over-heating the material.

        3. All polish marks must be made in a radial direction from the vane ID to OD.

        4. The surface finish of the repair area must be the same as the adjacent area.

        5. Refer to the SPM TASK 70-35-03-300-501.

      3. Hand polish the vane leading and/or trailing edge radius and the vane profile to make a smooth shape.

        1. Remove the minimum quantity of material necessary to make the correct radius.

        2. Refer to the SPM TASK 70-35-03-300-501.

    2. SUBTASK 72-32-91-220-079 Examine the LPC Inlet Guide Vane Assembly

    1. Refer to Figure, Figure and Figure.

      2. Visually and dimensionally examine the repaired area.

        1. Nicks, dents, scores, galls and a change in color to a darker than light straw color are not permitted.

        2. Refer to TASK 72-32-91-200-000 (INSPECTION-000).

    3. SUBTASK 72-32-91-110-061 Do A Swab Etch

      1. Chemically clean.

        1. Refer to the SPM TASK 70-11-08-300-503, SUBTASK 70-11-08-300-001.

        1. Use Chemical cleaning equipment.

      2. Swab etch the repaired area.

        1. Refer to the SPM TASK 70-11-08-300-503, SUBTASK 70-11-08-300-002.

        1. Use Chemical cleaning equipment.

    4. SUBTASK 72-32-91-230-058 Examine the LPC Inlet Guide Vane Assembly for Cracks

      1. Do a fluorescent penetrant examination of the repaired area.

        1. Refer to the SPM TASK 70-23-05-230-501.

        1. Make sure that there are no cracks in the repaired area.
