Procedure

    1. SUBTASK 72-50-22-320-055 Machine the Outer Buttress Platform Front Lips

      NOTE

      If the outer buttress platform front lips were plasma spray repaired before, remove the old coating fully.

      1. Machine the radial dimension D1.

      1. Refer to Figure.

        Use IAE 3M14367 Turning fixture 1 off and vertical turning lathe.

        Remove the old coating and damage fully.

        Keep the material removal to the minimum to allow for subsequent repairs.

    2. SUBTASK 72-50-22-220-256 Examine the Machined Surfaces

      1. Dimensionally examine.

      1. Refer to Figure.

        Write down the radial dimension D1.

        Use radius gage set and dial caliper.

    3. SUBTASK 72-50-22-230-116 Examine the Machined Surfaces for Cracks

      1. Do the test for cracks.

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