SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European [[Page 34759]] Community, has issued EASA AD 2018-0128, dated June 12, 2018 (referred to hereinafter as ``the MCAI''), to address an unsafe condition for the specified products. The MCAI states: Occurrences were reported on RR Trent 1000 `Pack B' engines, where some IPC Rotor 1 and Rotor 2 blades were found cracked. This condition, if not detected and corrected, could lead to in- flight blade release, possibly resulting in reduced control of the aeroplane. To address this potential unsafe condition, RR issued the NMSB and the applicable NMSB to provide instructions to inspect IPC Rotor 1 blades, IPC Rotor 2 blades (front and rear face) and IPC shaft Stage 2 dovetail posts. For the reason described above, this [EASA] AD requires a one- time inspection of the affected parts and, depending on the findings, accomplishment of applicable corrective action(s). You may obtain further information by examining the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-0590. Related Service Information Under 1 CFR Part 51 We reviewed RR Alert Non-Modification Service Bulletin (NMSB) Trent 1000 72-AK130, Initial Issue, dated June 11, 2018. The NMSB describes procedures for performing a one-time inspection of the IPC stage 1 rotor blades, IPC stage 2 rotor blades, and IPC stage 2 dovetail posts, and lists engine serial numbers. 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 We reviewed RR NMSB Trent 1000 72-K099, Initial Issue, dated June 11, 2018; RR NMSB Trent 1000 72-K100, Initial Issue, dated June 11, 2018; and RR NMSB Trent 1000 72-K129, Initial Issue, dated June 11, 2018. RR NMSB Trent 1000 72-K099 describes procedures for an ultrasonic inspection of the IPC stage 1 rotor blades. RR NMSB Trent 1000 72-K100 describes procedures for a visual borescope inspection of the IPC stage 2 rotor blades and IPC stage 2 dovetail posts. RR NMSB Trent 1000 72- K129 describes procedures for an ultrasonic inspection of the IPC stage 2 rotor blades. FAA's Determination This product has been approved by EASA and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all the relevant information provided by EASA 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 inspecting the IPC stage 1 rotor blades, IPC stage 2 rotor blades, and IPC stage 2 dovetail posts, and removing any cracked parts from service. FAA's Justification and Determination of the Effective Date No domestic operators use this product. Therefore, we find good cause that notice and opportunity for prior public comment are unnecessary. In addition, for the reason 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- 0590 and Product Identifier 2018-NE-24-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 0 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 ---------------------------------------------------------------------------------------------------------------- Inspect IPC blades and dovetail post.. 20 work-hours x $85 per $0 $1,700 $0 hour = $1,700. ---------------------------------------------------------------------------------------------------------------- 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 [[Page 34760]] 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 this AD: (1) Is not a ``significant regulatory action'' under Executive Order 12866, (2) Is not a ``significant rule'' under the 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): 2018-13-07 Rolls-Royce plc: Amendment 39-19319; Docket No. FAA-2018- 0590; Product Identifier 2018-NE-24-AD. (a) Effective Date This AD is effective August 7, 2018. (b) Affected ADs None. (c) Applicability This AD applies to all Rolls Royce plc (RR) Trent 1000-A, Trent 1000-C, Trent 1000-D, Trent 1000-E, Trent 1000-G, and Trent 1000-H turbofan engine models. (d) Subject Joint Aircraft System Component (JASC) Code 7230, Turbine Engine Compressor Section. (e) Unsafe Condition This AD was prompted by reports of intermediate-pressure compressor (IPC) rotor blade cracks, which could lead to separations resulting in engine failures.
