ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-2B67, -2B67B, and -2B67/P turbofan engines. This AD was prompted by low-cycle fatigue (LCF) cracking of the fuel manifold leading to an engine fire. This AD requires removal from service of certain fuel manifolds at the next engine shop visit and their replacement with parts eligible for installation. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective January 4, 2019. ADDRESSES: For service information identified in this final rule, contact General Electric Company, GE Aviation, Room 285, 1 Neumann Way, Cincinnati, OH 45215; phone: 513-552-3272; email: [email protected].

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain GE GEnx-2B67, - 2B67B, and -2B67/P turbofan engines. The NPRM published in the Federal Register on August 3, 2018 (83 FR 38086). The NPRM was prompted by LCF cracking of the fuel manifold leading to an engine fire. The NPRM proposed to require removal from service of certain fuel manifolds at the next engine shop visit and their replacement with parts eligible for installation. We are issuing this AD to address the unsafe condition on these products. Revision to Related Service Information GE published GEnx-2B Service Bulletin (SB) 73-0038 R03, dated August 17, 2018, to provide operators with instructions for replacing the lower fuel manifold system when in the intermixed configuration. This SB eliminates the need to replace the top main and lower fuel manifolds in the shop. Comments We gave the public the opportunity to participate in developing this final rule. We have considered the comment received. The Boeing Company supported the NPRM. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed. Related Service Information We reviewed GE GEnx-2B SB 73-0038 R02, dated November 19, 2015, and GEnx-2B SB 73-0038 R03, dated August 17, 2018. GE GEnx-2B SB 73-0038 R02, dated November 19, 2015 describes procedures for removing and replacing the fuel manifold system with parts eligible for installation. GE GEnx-2B SB 73-0038 R03, dated August 17, 2018 describes procedures for replacing the fuel manifold system when in the intermixed configuration. Costs of Compliance We estimate that this AD affects two engines installed on airplanes of U.S. [[Page 61528]] registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Replace fuel manifolds............. 220 work-hours x $85 per $119,485 $138,185 $276,370 hour = $18,700. ---------------------------------------------------------------------------------------------------------------- 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. We are 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to engines, propellers, and associated appliances to the Manager, Engine and Propeller Standards Branch, Policy and Innovation Division. 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) Is not a ``significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and (4) 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1.
