    1. SUBTASK 73-11-41-350-051 Blend the Fuel Manifolds

    1. Refer to Figure.

      2. Blend nicks, chafing, pitting and scratches that are more than 0.003 in. (0.076 mm) in depth.

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

      2. Blend damage in straight length areas that are 1.000 in. (25.4 mm) from ferrules.

      3. The depth of the blends must not be more than 0.008 in. (0.203 mm) of the tube wall thickness.

      4. Blend in all directions so there will be less stress concentration.

      5. The blended area must not be more than 0.500 sq in. (323.0 sq mm). No more than one blend area is permitted circumferentially at a location.

      6. Blends must be a minimum of 1.000 in. (25.4 mm) apart.

    2. SUBTASK 73-11-41-220-053 Examine the Fuel Manifolds After Blend Repair

      1. Examine the blended areas

      1. Refer to Inspection-000 TASK 73-11-41-200-100.

    3. SUBTASK 73-11-41-790-052 Examine the Fuel Manifold for Leaks

      1. Do a pressure test to check for leaks.

      1. Refer to Inspection-001 TASK 73-11-41-200-101-A00, Step.
