ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GE90 turbofan engines. This AD was prompted by a report of an engine and airplane fire. This AD requires replacing affected fuel/oil lube/servo coolers (``main fuel oil heat exchangers'') with a part eligible for installation. We are issuing this AD to correct the unsafe condition on these products. DATES: This AD is effective May 22, 2017. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of May 22, 2017. 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 GE90 turbofan engines. The NPRM published in the Federal Register on December 7, 2016 (81 FR 88145) (``the NPRM''). The NPRM was prompted by a report of an engine and airplane fire. The NPRM proposed to require replacing affected fuel/oil lube/servo coolers (``main fuel oil heat exchangers'') with a part eligible for installation. We are issuing this AD to prevent failure of a main fuel oil heat exchanger, which could result in an engine fire. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment. Request To Revise Applicability Reference All Nippon Airways, MTU Maintenance Hannover GmbH (MTU), and Air New Zealand commented that this AD should list all vendor part numbers referenced in GE Service Bulletin (SB) GE90-100 S/B 79-0034, Revision 03, dated August 5, 2016. This would ensure that the applicability of the AD is not misinterpreted. We agree. We changed this AD by adding a reference in the Applicability paragraph to the respective vendor number after the part number. Request To Clarify Tracking of Accomplishment of AD MTU commented that clarification of the accomplishment of this AD is needed because GE SB GE90-100 S/B 79-0034, Revision 03, dated August 5, 2016, requires marking repaired parts with the suffix ``A'' at the end of the serial number but the proposed AD does not. MTU indicated that ``GE fleet highlites'' note that the suffix is not part of the actual serial number and must not appear on EASA or FAA documents. We disagree. Although we are not requiring that parts be marked with the suffix ``A'' to reflect compliance with this AD, these parts are typically marked after repair per the requirements of GE SB GE90- 100 S/B 79-0034. Operators are free, however, to devise an alternate tracking system, i.e. through part markings and/or records, to show that the part has been repaired and is eligible for installation. We did not change this AD. Request To Reference Latest Service Bulletin MTU requested that we change the reference to GE SB GE90-100 S/B 79-0034, Revision 03, dated August 5, 2016, to the ``latest version'' of this SB. We disagree. We cannot require compliance to a document that does not exist. We note that operators may submit a request for an alternate method of compliance if this SB is revised after the publication of this AD. We did not change this AD. Request To Revise References to Main Heat Exchanger GE requested that references in the AD to the ``main heat exchanger'' be changed to the ``main fuel oil heat exchanger'' and/or the ``MFOHE.'' GE indicated that ``main fuel oil heat exchanger'' is the term that it uses in communications with its operators. We agree. We changed references in this AD from ``main heat exchanger'' to ``main fuel oil heat exchanger.'' Request To Revise Description of Incident and Unsafe Condition Statement GE requested that we revise the discussion in the NPRM of the cause of the incident and the unsafe condition [[Page 18083]] statement. GE indicated that this AD should say: ``The incident investigation determined the cause to be the separation of a tube internal to the main fuel oil heat exchanger, which resulted in leakage of fuel into the oil system, causing fuel to flood the oil sump that overwhelmed the scavenge and venting system. This condition (engine with main fuel oil heat exchanger that has not been repaired), if not corrected, could result in failure of a main fuel oil heat exchanger, which could result in an engine fire.'' We disagree. The description of the incident in the NPRM is not repeated in this final rule AD. The description of the unsafe condition in this AD is accurate. These changes, therefore, are unnecessary. We did not change this AD. Support for the NPRM Federal Express and the Air Line Pilots Association expressed support for the NPRM as written. The Boeing Company and United Airlines indicated that they have no objections to the content of this NPRM. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed GE SB GE90-100 S/B 79-0034, Revision 03, dated August 5, 2016, and GE SB GE90 S/B 79-0058, Revision 02, dated August 5, 2016. These service bulletins describe procedures to repair and replace a main fuel oil heat exchanger. These documents are distinct since they apply to different engine models. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this AD affects 185 engines installed on airplanes of U.S. 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 main fuel oil heat exchanger 5 work-hours x $85 per $7,000 $7,425 $1,373,625 hour = $425. ---------------------------------------------------------------------------------------------------------------- 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. 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 to the extent that it justifies making a regulatory distinction, 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.
