Safety Requirements

CAUTION

THE WORD FOCUS, SPECIFIED IN SUBTASK TITLES, INDICATES CRITICAL LOCATIONS ON COMPONENTS TO WHICH SPECIAL ATTENTION MUST BE GIVEN.

Procedure

    1. SUBTASK 72-41-11-230-104 Do a General and Focus Inspection on Stages 3 to 8 HP Compressor Discs for Cracks

      CAUTION

      YOU MUST MAKE SURE ALL THE TAPE IS REMOVED AFTER THE INSPECTION.

      NOTE

      Use fluorescent penetrant inspection SPM TASK 70-23-04-230-501 or NMSB 72-0637. Using NMSB 72-0637 will earn longer ultrasonic inspection grace periods. Refer to NMSB 72-0637 for detail of grace periods.

      NOTE

      Use ultra high sensitivity fluorescent penetrant, for the inspection of all the components and for focus inspection of specified areas in this SUBTASK.

      2. Do a focus crack inspection of HP Compressor Stages 3 to 8 drum. While you complete the fluorescent penetrant inspection in Step special attention must be given to the focus areas listed in the locations that follow:

        1. Stages 3, 4, 5, 6, 7 and 8 disc bores.

          1. Cracked.

          1. Reject.

        2. Stages 3, 4 and 5 dovetail post Zone B and bedding areas Zone A. Zone C is not part of the focus inspections.

          1. Cracked.

          1. Reject.

            NOTE

            One loading slot per disc, four locking slots per disc.

        3. Stages 6, 7 and 8 loading and locking slots.

          1. Cracked.

          1. Reject.

        4. Stage 8 bolt holes, Location 9.

          1. Cracked.

          1. Reject.

        5. Stage 6 HP Compressor disc circumferential seal grooves, Locations 1017 and 1020.

          1. Cracked.

          1. Reject.

        6. Stage 7 HP Compressor disc circumferential seal grooves, Locations 1266 and 1267.

          1. Cracked.

          1. Reject.

        7. Stage 8 HP Compressor disc circumferential seal grooves, Locations 1268 and 1269.

          1. Cracked.

          1. Reject.

        8. Stage 8 HP Compressor disc inner cavity profile, Location 10.

          1. Cracked.

          1. Reject.

      3. Remove any applied masking tape.

      1. If the part has operated with any standard of silver coated nut (up to and including SB 72-0596) installed in the stage 8 cavity, NMSB 72-0625 (Eddy Current Inspection (ECI)) can be accomplished as an additional option. Successful accomplishment of cleaning (TASK 72-41-11-100-001-A00 or TASK 72-41-11-110-001), fluorescent penetrant inspection (SPM TASK 70-23-04-230-501 or NMSB 72-0637) and an ECI will earn longer ultrasonic inspection grace periods. Refer to NMSB 72-0615 for details of grace periods.
