Turbofan Engines AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2018-10-11 for all CFM International S.A. (CFM) Model CFM56-7B engines. AD 2018- 10-11 required initial and repetitive inspections of certain fan blades and, if they fail the inspection, their replacement with parts eligible for installation. This superseding AD requires the same initial and repetitive inspections but revises the compliance time for the repetitive inspections. This AD was prompted by further analysis by the manufacturer that indicated a need to reduce the repetitive fan blade inspection interval based on ongoing root cause investigation of an April 2018 engine failure. The agency is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective October 16, 2018. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 16, 2018. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of May 14, 2018 (83 FR 19176, May 2, 2018). The FAA must receive any comments on this AD by November 15, 2018.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued AD 2018-10-11, Amendment 39-19286 (83 FR 22836, May 17, 2018), (``AD 2018-10-11''), for all CFM model CFM56-7B engines. AD 2018-10-11 required initial and [[Page 49273]] repetitive ultrasonic inspections (USI) or eddy current inspection (ECI) of certain fan blades and, if they fail the inspection, their replacement with parts eligible for installation. AD 2018-10-11 resulted from an April 2018 event involving an engine failure due to a fractured fan blade leading to the engine inlet cowl disintegrating and debris penetrating the fuselage, causing a loss of pressurization and prompting an emergency descent. One passenger fatality occurred as a result. The agency issued AD 2018-10-11 to prevent failure of the fan blade due to cracking, which could lead to an engine in-flight shutdown, uncontained release of debris, damage to the airplane, and possible airplane decompression. Actions Since AD 2018-10-11 Was Issued Since the FAA issued AD 2018-10-11, CFM gained a better understanding of the fan blade failures based on the inspections and further analysis of the detected cracks and the April 2018 event. As a result, CFM reduced the repetitive inspection interval to prevent a fan blade failure. CFM has published Service Bulletin (SB) CFM56-7B S/B 72- 1033, Revision 2, dated July 27, 2018, to reduce the repetitive inspection interval from 3,000 cycles to 1,600 cycles. The FAA expects that all affected engines will have completed the initial inspection based on the previously issued ADs. The FAA is issuing this AD to address the unsafe condition on these products. Revision to Cost Estimate The FAA has determined that, in AD 2018-10-11, it underestimated the cost per fan blade to be $8,500. However, based on CFM SB CFM56-7B S/B 72-1033, Revision 2, dated July 27, 2018, and earlier versions the estimated cost per fan blade should be $51,400. The FAA erroneously assumed the cost in the service bulletin represented the cost for a set of 24 fan blades when it actually represented the cost for two fan blades. In this final rule, the agency has updated the on-condition costs to reflect the correct cost of the fan blade. Related Service Information Under 1 CFR Part 51 The FAA reviewed CFM SB CFM56-7B S/B 72-1033, Revision 2, dated July 27, 2018, and Subtask 72-21-01-220-091, of Task 72-21-01-200-001, from the CFM56-7B Engine Shop Manual (ESM), Revision 57, dated January 15, 2018. CFM SB CFM56-7B S/B 72-1033, Revision 2, describes procedures for performing a USI of the affected fan blades. Subtask 72-21-01-220- 091, of Task 72-21-01-200-001, from the CFM56-7B ESM, describes procedures for performing an ECI of the affected fan blades. 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. Other Related Service Information The FAA also reviewed CFM SB CFM56-7B S/B 72-1019, dated March 24, 2017, CFM SB CFM56-7B S/B 72-1019, Revision 1, dated June 13, 2017, CFM SB CFM56-7B S/B 72-1024, dated July 26, 2017, CFM SB CFM56-7B S/B 72- 1033, dated April 20, 2018, and General Electric Field Support Technology (FST) Procedure 2370, dated December 9, 2016. These SBs and the FST provide information on performing the USI. FAA's Determination The FAA is issuing this AD because the agency has evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. AD Requirements This AD requires initial and repetitive USI or ECI of certain fan blades and, if they fail the inspection, their replacement with parts eligible for installation. FAA's Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule. Due to the reduction in the repetitive inspection interval, some fan blades have reached or exceeded the revised repetitive inspection threshold. Because of this, the compliance time for the required action is shorter than the time necessary for the public to comment and for the FAA to issue the final rule to ensure the unsafe condition is addressed. Therefore, the agency finds good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reasons stated in this paragraph, the FAA finds that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and the FAA did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, the agency invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA-2018-0785 and product identifier 2018-NE-14-AD at the beginning of your comments. The agency specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this final rule. The agency will consider all comments received by the closing date and may amend this final rule because of those comments. The FAA will post all comments it receives, without change, to http://www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact the agency receives about this final rule. Costs of Compliance The FAA estimates that this AD affects 3,716 engines installed on 1,858 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: Estimated Inspection Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost inspection operators ---------------------------------------------------------------------------------------------------------------- Inspect engine fan blade.............. 2 work-hours x $85 per $0 $170 $631,720 hour = $170. ---------------------------------------------------------------------------------------------------------------- The FAA estimates the following costs to complete any necessary replacement of a single fan blade that would be required based on the results of the inspection. The agency has no way of determining the number of [[Page 49274]] engines that might need fan blades to be replaced: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replace fan blade............................. 1 work-hour x $85 per hour = $85 $51,400 $51,485 ---------------------------------------------------------------------------------------------------------------- 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. 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 within the Aircraft Certification Service, 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.

(d) Subject Joint Aircraft System Component (JASC) Code 7230, Turbine Engine Compressor Section. (e) Unsafe Condition This AD was prompted by further analysis by the manufacturer that indicated a need to reduce the repetitive fan blade inspection interval based on ongoing root cause investigation of an April 2018 engine failure that resulted in one fatality. The FAA is issuing this AD to reduce the repetitive fan blade inspection interval to prevent failure of the fan blade. The unsafe condition, if not addressed, could result in failure of the fan blade, the engine inlet cowl disintegrating and debris penetrating the fuselage, causing a loss of pressurization, and prompting an emergency descent. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions (1) Perform an ultrasonic inspection (USI) or eddy current inspection (ECI) of the concave and convex sides of the fan blade dovetail as follows: (i) Before further flight, perform an initial inspection of the fan blade using the criteria in Planning Information, either paragraph 1.C.(2)(a), 1.C.(2)(b), or 1.C.(2)(c), of CFM Service Bulletin (SB) CFM56-7B S/B 72-1033, Revision 2, dated July 27, 2018. (ii) For all fan blades not inspected in accordance with (g)(1)(i) of this AD, perform an initial inspection prior to accumulating 20,000 flight cycles on the fan blade or before further flight, whichever occurs later. (iii) Thereafter, repeat this inspection no later than 1,600 cycles since the last inspection or within 450 cycles after the effective date of this AD, whichever occurs later. (iv) Use the Accomplishment Instructions, paragraphs 3.A.(3)(a) through (i), of CFM SB CFM56-7B S/B 72-1033, Revision 2, dated July 27, 2018, to perform a USI or use the instructions in subtask 72-21- 01-220-091, of task 72-21-01-200-001, from CFM CFM56-7B Engine Shop Manual (ESM), [[Page 49275]] Revision 57, dated January 15, 2018, to perform an ECI. (2) If any unserviceable indication, as specified in the applicable service information in paragraph (g)(1)(iv) of this AD, is found during the inspections required by paragraph (g) of this AD, replace the fan blade before further flight with a part eligible for installation. (h) Installation Prohibition Do not install any replacement fan blade unless it meets one of the following criteria: (1) The replacement fan blade has fewer than 20,000 cycles since new, or; (2) The replacement fan blade has been inspected in accordance with paragraph (g) of this AD. (i) Definition For the purpose of this AD, a ``replacement fan blade'' is a fan blade that is being installed into an engine from which it was not previously removed. Removing and reinstalling a fan blade for the purpose of relubrication is not subject to the Installation Prohibition of this AD. (j) Credit for Previous Actions You may take credit for the actions that are required by paragraph (g) of this AD if you performed the actions before the effective date of this AD using CFM SB CFM56-7B S/B 72-1019, dated March 24, 2017; CFM SB CFM56-7B S/B 72-1019, Revision 1, dated June 13, 2017; CFM SB CFM56-7B S/B 72-1024, dated July 26, 2017; CFM SB CFM56-7B S/B 72-1033, dated April 20, 2018; CFM SB CFM56-7B S/B 72- 1033, Revision 1, dated May 9, 2018; or an ECI using the instructions in task 72-21-01-200-001, subtask 72-21-01-220-091 of CFM56-7B ESM, earlier than Revision 57, dated January 15, 2018.
