Procedure

    1. SUBTASK 72-50-53-350-085 Blend the Damaged Surfaces on the Turbine Exhaust Case

    1. Refer to Figure.

      2. General.

      1. Blend using the SPM TASK 70-35-21-350-501.

        Blend in a circumferential direction.

        Do not blend along the axis when you blend a cylindrically-shaped part.

        The length to depth ratio of a blend must be a minimum of 10 to 1.

        The minimum distance between blends must be 0.500 in. (12.70 mm).

        When two or more damaged areas are near each other, blend the areas together.

        Put the surface texture back to that of the adjacent areas without damage.

      3. Blend the damaged surfaces on the turbine exhaust case. Refer to Figure.

        1. Blend damage in Area A.

        1. The maximum blend depth is 0.024 in. (0.61 mm).

        2. Blend damage in Area B.

        1. Blend the inner diameter of the bushings to remove high metal.

        3. Blend damage in Area C (the leading and trailing edges of the strut).

        1. The maximum blend depth must be 0.020 in. (0.51 mm).

      4. Do not blend in Area D.

        5. Blend damage on the airfoil.

        1. The maximum blend depth must be 0.010 in. (0.25 mm).

        6. Blend areas other than (1) thru (5).

        1. Blend nicks, dents and scratches. Keep the removal of material to the minimum necessary to remove the damage.

      4. Blend the damaged surfaces on the stiffening rails and the mount lugs. Refer to Figure.

        1. Blend the damage in Area E, both stiffening rails.

        1. Maximum blend depth is 0.0150 in. (0.381 mm).

          Bulging damage on the forward and aft sides of the rails can be blended as necessary. Blend the bulges to be flush with rail areas that do not have damage. Remove a minimum amount of parent material.

          Local minimum rail thickness must not be less than 0.150 in. (3.81 mm) after blend repair.

        2. Blend the damage in Area F, all mount lugs.

        1. Maximum blend depth is 0.055 in. (1.40 mm).

          Local minimum wall thickness must not be less than 0.600 in. (15.24 mm) after blend repair. The minimum distance between the mount lug OD and the bushing bore OD must not be less than 0.600 in. (15.24 mm ) after blend repair.

        3. Blend the damage in Area G, all mount lugs.

        1. Maximum blend depth is 0.010 in. (0.25 mm).

          Local minimum wall thickness must not be less than 0.600 in. (15.24 mm) after blend repair. The minimum distance between the mount lug OD and the bushing bore OD must not be less than 0.600 in. (15.24 mm ) after blend repair.

      4. Do not blend in Area H, the mount lug bushing bores.

    2. SUBTASK 72-50-53-230-080 Examine the Repair

      1. Do a fluorescent penetrant inspection after blend repair.
