P LA N N I N G I N F O R M A T I O N A. E f fe ct i v i ty GE90-110B1 and -115B This Service Bulletin is applicable to all GE90-100 engines. The spool stages 2-5 [high pressure compressor (HPC) stage 2-5 spools] P/N 351-103-106-0, P/N 351-103-107-0, P/N 351-103-141-0, P/N 351-103-142-0, P/N 351-103-144-0, P/N 351-103-145-0, P/N 351-103-148-0, P/N 351-103-149-0, and P/N 351-103-151-0 are affected by this Service Bulletin. N O T E : The HPC stage 2-5 spools with serial numbers listed in paragraph 4., A P P E N D I X

- A are affected by this Service Bulletin. B. D e s c r i p t i o n This Service Bulletin provides instructions to replace the affected HPC stage 2-5 spools with a replacement HPC stage 2-5 spool. This Service Bulletin also gives instructions to label, or mark and scrap the removed HPC stage 2-5 spool. C. C o m p l i a n ce Category 2 GE recommends that you do this Service Bulletin as follows:



# . If the HPC stage 2-5 spool has greater than 5,800 cycles since new (CSN), remove within 3 months from the issue date of this Service Bulletin, but before 6,000 CSN.



# . If the HPC stage 2-5 spool has greater than 5,500 CSN and less than 5,800 CSN, remove within 6 months from the issue date of this Service Bulletin, but before 6,000 CSN.



# . If the HPC stage 2-5 spool has less than 5,500 CSN, remove before reaching 5,800 CSN. N O T E 1 : This Service Bulletin is not intended to extend the life limit of any HPC stage 2-5 spools. If the published life limit for a part in the GE90-100 Engine Manual (EM) Chapter 05 is lower than the removal thresholds in paragraph 1.C., C o m p l i a n ce , the Chapter 05 life limit supersedes recommendations in this Service Bulletin. N O T E 2 : This Service Bulletin can be accomplished in shop. This Service Bulletin is offered to improve the reliability or performance of your GE product, or to help prevent the occurrence of the event or condition described in this Service Bulletin. If the operator elects not to participate in the bulletin, that decision

D. C o n c u rre n t Re q u i re m e n ts None. E. R e a s o n (1) Objective: To improve reliability and remove parts from service. (2) Condition: HPC stage 2-5 spools in service have experienced micro-cracks in the HPC stage 5-6 seal teeth spacer arm. (3) Cause: Elevated stresses due to coating application process and elevated temperatures. (4) Improvement: The affected HPC stage 2-5 spools will be removed from service and replaced. (5) Substantiation: Substantiation is by analysis and comparative analysis. F. A p p rova l This Service Bulletin contains no modi fi cation information that revises the approved con fi guration and therefore does not require FAA approval. G.

(a) Attach a cardboard or metal label (tag) with "NON SERVICEABLE" marked on it to the affected HPC stage 2-5 spool (1). Refer to the SPM, 70-16-02, TEMPORARY MARKING. OR (b) Mark "NON SERVICEABLE" on the affected HPC stage 2-5 spool (1, Figure 1). Use a marking pen (C05-003) or equivalent. Refer to the SPM, 70-16-02, TEMPORARY MARKING. (5) Make sure that the "NON SERVICEABLE" mark can be read and the label is attached tightly to prevent the HPC stage 2-5 spool (1, Figure 1) from being reinstalled after removal. (6) Remove the affected HPC stage 2-5 spool (1). Refer to the GE90-100 EM, 72-31-00, DISASSEMBLY 001 or DISASSEMBLY 002. (7) Install a replacement HPC stage 2-5 spool (1, Figure 1). Refer to the GE90-100 EM, 72-31-00, ASSEMBLY 001 or ASSEMBLY 002. (8) Assemble the HPC rotor assembly. Refer to the GE90-100 EM, 72-31-00, ASSEMBLY 001 or ASSEMBLY 002.
