Procedure

    1. SUBTASK 72-41-12-350-179 Blend to Remove Scoring

    1. Refer to Figure.

      2. Blend to remove scoring from the HPC Vortex Reducer Ring Surface Assembly, surface at Location 3 by SPM TASK 70-35-03-300-501.

      1. Blend the damage to maximum depth of 0.005 in. (0.127 mm).

      2. Total depth of material removed includes the depth of any material removed in previous blend application and current application of this repair.

      3. The minimum blend length to depth ratio is 50 to 1 circumferentially and 15 to 1 axially.

      4. Blend must be smooth and continuous with adjacent surfaces.

      5. Remove the minimum amount of parent material necessary to accomplish the repair.

      6. Blends must not encroach into the adjacent fillet radius.

      7. Blends are permissible to extend up to AVT hole edge but must not enter onto the AVT hole diameter.

    2. SUBTASK 72-41-12-110-172 Swab Etch the Repaired Area(s)

    1. Refer to Figure.

    2. Swab etch the repaired area(s) of HPC Vortex Reducing Ring by SPM TASK 70-11-08-300-503.

    3. SUBTASK 72-41-12-220-211 Do a Binocular Inspection

    1. Refer to Figure.

      2. Do a binocular inspection of the repaired area(s).

      1. Use 3 - 10X binoculars.

      2. Make sure that there are no indications of defects on the repaired surfaces.

      3. Make sure there is no raised metal remaining.

    4. SUBTASK 72-41-12-230-150 Do a Fluorescent Penetrant Inspection

    1. Refer to Figure.

      2. Do a fluorescent penetrant inspection of the repaired area(s) by SPM TASK 70-23-05-230-501.

      1. Cracks are not permitted.

    5. SUBTASK 72-41-12-350-180 Polish the Swab Etch Area(s)

    1. Refer to Figure.

    2. Polish the swab etch area(s) by SPM TASK 70-35-03-300-501.

    6. SUBTASK 72-41-12-220-212 Do a Dimensional Inspection

    1. Refer to Figure.

      2. Do a dimensional inspection of the part.

      1. Make sure that post blend depth is not more than 0.005 in. (0.127 mm).

    7. SUBTASK 72-41-12-350-181 Mark the Part

      1. Mark VRS9531 adjacent to the part number. See Figure for marking location.

      1. Make a permanent mark by the procedure given in the SPM TASK 70-09-00-400-501, SUBTASK 70-09-00-400-001. Use vibro-engraving equipment.
