Procedure

    1. SUBTASK 72-32-82-350-076 Remove the Damage from the LPC Stage 2.0 Blades

      1. CAUTION

        WHEELS, STONES AND ABRASIVE PAPERS USED TO DRESS, MAKE SMOOTH, OR POLISH A TITANIUM COMPONENT MUST BE OF THE SILICON CARBIDE TYPE. ALUMINUM OXIDE TYPE MUST NOT BE USED.
        THE MATERIAL WILL OXIDIZE AND CRACK IF MECHANICAL CUTTERS ARE USED HEAVILY. THIS HAS OCCURRED IF COMPONENT SHOWS DARK STRAW TO BLUE DISCOLORATION. IF AT ANYTIME THIS COLORATION OCCURS, THE COMPONENTS MUST BE REJECTED.

        Scallop, make smooth and/or hand polish to remove nicks, scratches and/or damage.

        1. Use abrasive stone or papers and/or fine file. Use light pressure to prevent any risk of overheating material.

        1. Any polish marks must be made in a radial direction from root to tip of the blades.

        2. Surface finish of the repair area must be the same as the adjacent area.

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

        1. Remove the minimum amount of material necessary to give the correct radius.

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

        3. Refer to Figure.

    2. SUBTASK 72-32-82-220-096 Examine the LPC Stage 2.0 Blades

      1. Do a visual and dimensional examination on the blades.

        1. Visually examine the repaired area for nicks, scratches and/or damage using 10X magnifying glass.

        1. Follow the inspection procedure as given in TASK 72-32-82-200-000.

    3. SUBTASK 72-32-82-230-062 Examine the LPC Stage 2.0 Blade for Cracks

        1. Refer to SPM TASK 70-23-01-230-501.

        1. Cracks are not permitted.

    4. SUBTASK 72-32-82-350-077 Glass Bead Peen the LPC Stage 2.0 Blades

    1. NOTE

      This is an optional procedure. Do this SUBTASK if necessary after blending to remove the damage from area 1, 2 and 3, refer to Figure.

      Glass bead peen if the airfoil has been repaired.

      2. Apply the adhesive tape.

        1. Apply CoMat 02-003 ADHESIVE TAPE BLACK WATERPROOF to the areas which are not to be given glass peening.

        1. Refer to Figure.

      3. Install the blades in to the glass peening fixture.

      4. Glass bead peen the airfoil.

        1. Refer to Figure.

        2. Use IAE 3J13167 Glass peening fixture 1 off hold an Almen test-strip.

        3. Refer to SPM TASK 70-38-04-300-503.

    5. Remove the blades from the fixture and remove the masking tape.

      6. Remove the glass beads.

        1. Use a clean dry air blast or a soft brush.

        1. Use a vacuum assisted brush to make sure all the glass beads are removed.

      7. Examine the blades.

        1. Visually examine the peened surface for uniform coverage and complete over-lapping of the shot impressions.

        1. Refer to SPM TASK 70-38-04-300-503.

    5. SUBTASK 72-32-82-380-059 Shot Peen the LPC Stage 2.0 Blades

      This is an optional procedure. Do this SUBTASK if necessary after blending to remove the damage from locations 4, 5, 8, 9 and 11, refer to Figure.

      Shot peen if the areas below the platform of the airfoil have been repaired.

      2. Apply the adhesive tape.

        1. Apply the adhesive tape to the area which are not to be given shot peening.

        1. Refer to Figure.

      3. Install the blades in the shot peening fixture.

      4. Shot peen the repaired area of the blade shank.

        1. Refer to Figure.

        1. Use CoMat 05-030 CAST STEEL SHOT DELETED at an intensity of 6A-8A.
