Procedure

    1. SUBTASK 73-13-41-320-004 Remove the Lower Right and Left Fairing from the Fuel Nozzle and Support Assembly

    1. Refer to Figure and Figure.

    2. CAUTION

      DO NOT MACHINE INTO THE INNER HEATSHIELD, INDEX 9, OF Figure AND Figure.

      Remove the right and left fairing by machining the welds that hold the fairing to the support. Refer to Locations L and M of Figure and Figure.

    3. CAUTION

      DO NOT REMOVE ANY MORE PARENT MATERIAL THAN IS NECESSARY TO REMOVE THE WELD.

      If necessary, machine any remaining weld material from the support.

    2. SUBTASK 73-13-41-320-005 If Necessary, Remove the Upper Right and Left Fairing

    1. Refer to Figure and Figure.

    2. Remove the fairing by machining the welds that hold the fairing to the support. Refer to Locations J and K of Figure and Figure.

      NOTE

      Replacement of upper right and left fairing does not apply to Nozzle and Support Assembly, PN 2A0993.

    3. CAUTION

      DO NOT REMOVE ANY MORE PARENT MATERIAL THAN IS NECESSARY TO REMOVE THE WELD.

      If necessary, machine any remaining weld material from the support.

    3. SUBTASK 73-13-41-220-093 Dimensional Inspection

    1. Refer to Figure and Figure.

    2. If the lower right and left fairings were removed from the support, make a dimensional inspection of the support. Refer to Figure and Figure, Index 2.

    3. If the upper right and left fairings were removed from the support, make a dimensional inspection of the support. Refer to Figure and Figure, Index 3.

    4. SUBTASK 73-13-41-230-058 Examine the Fuel Nozzle and Support Assembly After Fairing Removal

    1. Do a fluorescent penetrant inspection of the support where the welds held the fairing Ref SPM TASK 70-23-05-230-501. Use CoMat 06-064 FLUORESCENT PENETRANT (WATER WASHABLE MEDIUM SENSITIVITY).

    2. No cracks are permitted on the support.

    5. SUBTASK 73-13-41-110-059 Clean the Fuel Nozzle and Support Assembly and Replacement Fairing

    1. Clean the repair of the fuel nozzle and support assembly and the replacement fairing. Refer to SPM TASK 70-11-26-300-503.

    6. SUBTASK 73-13-41-310-053 If Necessary, Weld the Replacement Upper Right and Left Fairings to the Fuel Nozzle and Support Assembly

      NOTE

      If the upper fairings do not need to be replaced, go to Step.

    1. Refer to Figure and Figure.

      2. Position the new fairing on the support.

      1. Make sure that the fairing contact the support at Location J.

      2. Locate the upper edges of the upper fairing from Plane A as shown by Index 1.

      3. Plug weld the fairing at Location J.

      1. Weld by the manual gas tungsten arc method (IAE 16A) in SPM TASK 70-31-13-310-501.

      3. The eight tangs must be consumed by the weld.

        NOTE

        The tangs may move during the weld procedure.

      4. Weld the fairing at Location K in two places (both sides of fairing).

      1. Weld by the manual gas tungsten arc method (IAE 16A) per SPM TASK 70-31-13-310-501.

      3. Weld beads may be 0.060 in. (1,524 mm) maximum above the contour.

    7. SUBTASK 73-13-41-310-054 Weld the Replacement Lower Right and Left Fairing to the Fuel Nozzle and Support Assembly

    1. Refer to Figure and Figure.

      2. Position the new fairing on the support, Refer to Figure and Figure.

      1. Make sure that the fairing contacts the support at Location L.

      2. Locate the fairing from Plane A as shown by Index 1.

      3. Weld the fairing at Location L.

      1. Weld by the manual gas tungsten arc method (IAE 16A) in SPM TASK 70-31-13-310-501.

      4. Weld the fairing at Location M, two places.

      1. Weld by the manual gas tungsten arc method (IAE 16A) in SPM TASK 70-31-13-310-501.

      3. A weld head of 0.030 in. (0,762 mm) maximum above contour is permitted.

    8. SUBTASK 73-13-41-230-059 Examine the Fuel Nozzle and Support Assembly After Repair

      1. Do a Fluorescent penetrant inspection of the fuel nozzle and support assembly after the fairing weld replacement.

      1. Examine the fuel nozzle and support assembly by fluorescent penetrant inspection method where the fairings were replaced.

      3. No cracks are permitted.

    9. SUBTASK 73-13-41-220-094 Do a Dimensional Inspection of the Fuel Nozzle and Support Assembly

    1. Do a dimensional inspection of the fuel nozzle and support assembly. Refer to Figure, Figure, Figure and Figure.
