SUPPLEMENTARY INFORMATION: Discussion We received information concerning damage to the engine fan hub found during an engine shop visit of an IAE PW1100G-series turbofan engine. The damage is believed to be the result of the installation of the inlet cone without using alignment pins, which might lead to bolts impacting and damaging the engine fan hub. This condition, if not addressed, could result in uncontained failure of the engine fan hub, damage to the engine, and damage to the airplane. We are issuing this AD to address the unsafe condition on these products. Related Service Information Under 1 CFR Part 51 We reviewed Pratt & Whitney (PW) Service Bulletin (SB) PW1000G-C- 72-00-0104-00A-930A-D, Issue No. 002, dated May 31, 2018. The SB describes procedures for performing a one-time visual inspection of the inlet cone mating face and counter weight flange on the engine fan hub assembly for surface damage. 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. FAA's Determination We are issuing this AD because we 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 a one-time visual inspection of the engine fan hub for damage, and replacement of the engine fan hub if damage or defects are found that are outside of serviceable limits. Differences Between the AD and the Service Information PW SB PW1000G-C-72-00-0104-00A-930A-D, Issue No. 002, dated May 31, 2018, only applies to PW1100G-JM engine models in service. This AD applies to all PW1100G-JM engine models certified under type certificate E00087EN. PW SB PW1000G-C-72-00-0104-00A-930A-D also excludes from its applicability certain serial numbered engines. We have no way to determine if these engines have been inspected and are therefore including these engines in the applicability of this AD. Interim Action We consider this AD interim action. An investigation to determine the cause of the failure is on-going and we may consider additional rulemaking if final action is identified. [[Page 29666]] 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 because the compliance time is less than the time required for public comment. In addition, all engine fan hubs must be inspected, and if needed, replaced before further flight. Therefore, we find good cause that notice and compliance for prior public comment are impracticable. In addition, for the reasons stated above, we find 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 was not preceded by notice and an opportunity for public comment. However, we invite 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- 0564 and Product Identifier 2018-NE-23-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this final rule. We will consider all comments received by the closing date and may amend this final rule because of those comments. We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this final rule. Costs of Compliance We estimate that this AD affects 14 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 ---------------------------------------------------------------------------------------------------------------- Visual inspection.................. 2 work-hours x $85 per hour $0 $170 $2,380 = $170. ---------------------------------------------------------------------------------------------------------------- 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. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2018-13-03 International Aero Engines: Amendment 39-19315; Docket No. FAA-2018-0564; Product Identifier 2018-NE-23-AD. (a) Effective Date This AD is effective July 11, 2018. (b) Affected ADs None.

The unsafe condition, if not addressed, could result in uncontained failure of the engine fan hub, damage to the engine, and damage to the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. [[Page 29667]] (g) Required Actions Within 90 days after the effective date of this AD: (1) For engines installed on an airplane, perform a visual inspection of the engine fan hub, in accordance with the Accomplishment Instructions, paragraphs 1.E.(1) to 1.E.(4), of Pratt & Whitney (PW) Service Bulletin (SB) PW1000G-C-72-00-0104-00A-930A- D, Issue No. 002, dated May 31, 2018. (2) For engines not installed on an airplane, perform a visual inspection of the engine fan hub, in accordance with the Accomplishment Instructions, paragraphs 2.D.(1) to 2.D.(4), of PW SB PW1000G-C-72-00-0104-00A-930A-D, Issue No. 002, dated May 31, 2018.
