| This Service Bulletin is applicable to all GEnx-1B engines. |
| The turbine rear frames (TRFs) P/N 10054251, P/N 10067452, P/N 10070017, P/N 10075904, P/N 10131146, P/N 10140751, and P/N 10140753 (all TRFs) are affected by this Service Bulletin. |
| B. | Description |
| This Service Bulletin releases TRF subassembly parts to the GEnx-1B Engine Illustrated Parts Catalog (EIPC) that originally were inseparable parts with the TRF. |
| C. | Compliance |
| Category 9 |
| Information only. |
| D. | Concurrent Requirements |
| None. |
| E. | Reason |
| (1) | Objective: |
| To list TRF subassembly parts in the GEnx-1B EIPC for potential future use during disassembly/assembly of the TRF prior to repair process. |
| (2) | Condition: |
| There are no subassembly parts of the TRF listed in the GEnx-1B EIPC. |
| (3) | Cause: |
| The TRF is listed in the GEnx-1B EIPC as an inseparable assembly. |
| (4) | Improvement: |
| The TRF subassembly parts were listed under the main frame assembly to support the disassembly/assembly procedure of the eductor tube, rake bosses, bolts, brackets, inserts, and covers listed in the new TRF repairs. Parts are not available for ordering until after a future release of a Category 8 Service Bulletin (Spare Parts Release), which will allow ordering regardless the repair process. |
| (5) | Substantiation: |
| The TRF subassembly parts are already certified, but not listed in the GEnx-1B EIPC. |
| F. | Approval |
| This Service Bulletin contains no modification information that revises the approved configuration and therefore does not require regulatory approval. |
| G. | Manpower |
| No additional man-hours are required to comply with this Service Bulletin. |
| H. | Weight and Balance |
| Weight and balance are not changed. |
