AD 2022-23-09

75918 Federal Register / Vol. 87, No. 237 / Monday, December 12, 2022 / Rules and Regulations the initial inspection required by paragraph (i) of this AD has been done. Although BAE Systems (Operations) Limited Inspection Service Bulletin ISB.32–156, Revision 1, dated July 3, 2001, specifies to report certain information to the manufacturer, this AD does not require a report. (1) If the number of flight cycles accumulated on the side stay can be positively determined: Inspect before the accumulation of 2,000 total flight cycles on the side stay, or within 500 flight cycles after May 2, 2005 (the effective date of AD 2005– 06–14), whichever occurs later. (2) If the number of flight cycles accumulated on the side stay cannot be positively determined: Inspect within 500 flight cycles after May 2, 2005 (the effective date of AD 2005–06–14). (h) Retained Optional Terminating Action for Paragraph (g) of This AD, With No Changes This paragraph restates the optional terminating action of paragraph (g) of AD 2005–06–14, with no changes. Relocation of each affected grease nipple to the upper surface of the outer link of the MLG side stays terminates the repetitive inspections required by paragraph (g) of this AD, if the relocation action is done in accordance with paragraph 2.C. of the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.32– 156, Revision 1, dated July 3, 2001. (i) New Requirements Except as specified in paragraph (j) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, United Kingdom Civil Aviation Authority AD G–2022–0018, dated October 18, 2022 (U.K. CAA AD G–2022– 0018). (j) Exceptions to U.K. CAA AD G–2022–0018 (1) Where U.K. CAA AD G–2022–0018 refers to its effective date, this AD requires using the effective date of this AD. (2) The ‘‘Remarks’’ section of U.K. CAA AD G–2022–0018 does not apply to this AD. (3) Where paragraph (2) of U.K. CAA AD G–2022–0018 refers to ‘‘discrepancies ( i.e. cracks or other adverse findings),’’ replace the text ‘‘discrepancies ( i.e. cracks or other adverse findings),’’ with ‘‘any cracking.’’ (4) Where U.K. CAA AD G–2022–0018 refers to ASB.32–A189, this AD requires using BAE Systems (Operations) Limited Alert Service Bulletin ASB.32–A189, dated September 16, 2022. (k) No Reporting Requirement Although BAE Systems (Operations) Limited Alert Service Bulletin ASB.32–A189, dated September 16, 2022, specifies to submit certain information to the manufacturer, this AD does not include that requirement.

ACTION : Final rule. SUMMARY : The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GE90– 90B, GE90–94B, GE90–110B1, and GE90–115B model turbofan engines. This AD was prompted by a manufacturer investigation that revealed that certain high-pressure turbine (HPT) stage 1 disks, HPT stage 2 disks, and stages 7–9 compressor rotor spools were manufactured from powder metal material suspected to contain iron inclusion. This AD requires the replacement of the affected HPT stage 1 disks, HPT stage 2 disks, and stages 7– 9 compressor rotor spools. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective January 17, 2023.

The AD docket contains this final rule, any comments received, and other information. The address for Docket Operations is U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE, Washington, DC 20590. FOR FURTHER INFORMATION CONTACT : Alexei Marqueen, Aviation Safety Engineer, ECO Branch, FAA, 1200 District Avenue, Burlington, MA 01803; phone: (781) 238–7178; email: Alexei.T.Marqueen@faa.gov . SUPPLEMENTARY INFORMATION : Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain GE GE90–90B, GE90– 94B, GE90–110B1, and GE90–115B model turbofan engines. The NPRM published in the Federal Register on September 09, 2022 (87 FR 55319). The NPRM was prompted by a manufacturer investigation that revealed that certain HPT stage 1 disks, HPT stage 2 disks, and stages 7–9 compressor rotor spools were manufactured from powder metal material suspected to contain iron inclusion. Further investigation by the manufacturer determined that the iron inclusion is attributed to deficiencies in the manufacturing process. The investigation by the manufacturer also determined that certain HPT stage 1 disks, HPT stage 2 disks, and stages 7– 9 compressor rotor spools made from billets manufactured using the same process may have reduced material properties and a lower fatigue life capability due to iron inclusion, which may cause premature fracture and uncontained failure. In the NPRM, the FAA proposed to require the replacement of certain HPT stage 1 disks, HPT stage 2 disks, and stages 7– 9 compressor rotor spools. The FAA is issuing this AD to address the unsafe condition on these products. Discussion of Final Airworthiness Directive Comments The FAA received comments from three commenters. The commenters were Air Line Pilots Association, International, FedEx Express, and The Boeing Company. All commenters supported the NPRM without change. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety requires adopting the AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. This AD is adopted as proposed in the NPRM. Related Service Information The FAA reviewed the following service information issued by GE, which specifies procedures for removing the affected HPT stage 2 disk from service. These documents are distinct since they apply to different engine models. • GE90–100 Service Bulletin 72–0893 R01, dated November 30, 2021. • GE90–100 Service Bulletin 72–0899 R00, dated April 29, 2022. The FAA also reviewed GE90–100 Service Bulletin 72–0897 R00, dated February 23, 2022. This service information specifies procedures for removing the affected stages 7–9 compressor rotor spool from service. The FAA also reviewed GE90 Service Bulletin 72–1214 R00, dated April 29, 2022. This service information specifies procedures for removing the affected HPT stage 1 disk and HPT stage 2 disk from service. Costs of Compliance The FAA estimates that this AD affects 1 engine installed on airplanes of U.S. registry. The FAA estimates that 0 engines installed on airplanes of U.S. registry require replacement of the HPT stage 1 disk or stages 7–9 compressor rotor spool. The FAA estimates the following costs to comply with this AD: E STIMATED C OSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Replace HPT stage 2 disk 8 work-hours × $85 per hour = $680 ........................ $459,473 (pro-rated) ........ $460,153 $460,153 Replace HPT stage 1 disk 8 work-hours × $85 per hour = $680 ........................ $867,041 (pro-rated) ........ 867,721 0 Replace stages 7-9 com- pressor rotor spool. 8 work-hours × $85 per hour = $680 ........................ $442,204 (pro-rated) ........ 442,884 0 Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency’s authority. The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
