SUPPLEMENTARY INFORMATION : Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0233, dated October 27, 2021 (EASA AD VerDate Sep<11>2014 16:21 Jun 16, 2022 Jkt 256001 PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 E:\FR\FM\17JNR1.SGM 17JNR1 lotter on DSK11XQN23PROD with RULES1

36388 Federal Register / Vol. 87, No. 117 / Friday, June 17, 2022 / Rules and Regulations 2021–0233) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus SAS Model A330–200 series airplanes, Model A330–200 Freighter series airplanes, and Model A330–300 series airplanes. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus SAS Model A330–200 series airplanes, Model A330–200 Freighter series airplanes, and Model A330–300 series airplanes. The NPRM published in the Federal Register on March 28, 2022 (87 FR 17198). The NPRM was prompted by a determination that tartaric sulfuric anodizing (TSA)/chromic acid anodizing (CAA) surface treatment in the door fitting attachment holes leads to a detrimental effect on fatigue behavior; and that certain service information specified in AD 2018–20– 19, Amendment 39–19453 (83 FR 52126, October 16, 2018) (AD 2018–20– 19) contains instructions that could be misleading, resulting in a necessary inspection not being accomplished on certain airplanes. The potentially misleading instructions are for an optional action, and apply only to model A330–200, A330–200 Freighter, and A330–300 airplanes. The NPRM proposed to require a rototest for certain modified airplanes for any crack around the right-side upper and lower bulk door support or door latch fitting holes at certain bulk cargo door frames, or repetitive inspections for any crack at certain fittings, and on-condition actions, as specified in EASA AD 2021– 0233. The FAA is issuing this AD to address possible fatigue cracks in the bulk cargo door frames, caused by TSA/CAA surface treatment in frame (FR) 67 and FR69 cargo door frame attachment holes. See the MCAI for additional background information. Discussion of Final Airworthiness Directive Comments The FAA received comments from the Air Line Pilots Association, International (ALPA) who supported the NPRM without change. Conclusion The FAA reviewed the relevant data, considered the comment received, and determined that air safety requires adopting this AD as proposed. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0233 specifies procedures for a rototest for any crack around the holes at the upper and lower door support fittings of frame FR67 and FR69 right hand side and the holes at door latch fitting of FR69 right hand side; or repetitive detailed inspections of the frame around the fittings, or high frequency eddy current (HFEC) and ultrasonic inspections of the upper door supper fitting holes and rototests of the lower door fitting holes of the door latch fittings at FR69 for any crack; and on- condition actions. On-condition actions include installing new (never installed on an airplane) bushes to the latch fittings of FR69 and repair, and a rototest of the support fittings and the frame holes at FR67. This material 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 The FAA estimates that this AD affects 109 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E STIMATED C OSTS FOR R EQUIRED A CTIONS Labor cost Parts cost Cost per product Cost on U.S. operators Up to 15 work-hours × $85 per hour = $1,275 ................................................................ $0 Up to $1,275 ....... Up to $138,975. The FAA estimates the following costs to do any necessary on-condition action that would be required based on the results of any required or optional actions. The FAA has no way of determining the number of aircraft that might need this on-condition action: E STIMATED C OSTS OF O N -C ONDITION A CTIONS Labor cost Parts cost Cost per product 3 work-hours × $85 per hour = $255 ...................................................................................................................... $1,915 $2,170 The FAA has received no definitive data on which to base the cost estimates for the repairs specified in this AD. 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. 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.

[FR Doc. 2022–13016 Filed 6–16–22; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2022–0589; Project Identifier AD–2022–00376–E; Amendment 39–22084; AD 2022–12–12] RIN 2120–AA64 Airworthiness Directives; Pratt & Whitney Division Turbofan Engines AGENCY : Federal Aviation Administration (FAA), DOT. ACTION : Final rule; request for comments. SUMMARY : The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney Division (PW) PW4062 model turbofan engines. This AD was prompted by a report of a manufacturing quality escape due to insufficient cooling of the low-pressure turbine (LPT) stage 5 air seal resulting in a reduction of the low-cycle fatigue (LCF) life limit. This AD requires removal and replacement of the LPT stage 5 air seal with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective July 5, 2022. The FAA must receive comments on this AD by August 1, 2022. ADDRESSES : You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow the instructions for submitting comments. • Fax: (202) 493–2251. • Mail: U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE, Washington, DC 20590. • Hand Delivery: Deliver to Mail address above between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. Examining the AD Docket You may examine the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA–2022–0589; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, any comments received, and other information. The street address for Docket Operations is listed above. FOR FURTHER INFORMATION CONTACT : Carol Nguyen, Aviation Safety Engineer, ECO Branch, FAA, 1200 District Avenue, Burlington, MA 01803; phone: (781) 238–7655; email: carol.nguyen@ faa.gov. SUPPLEMENTARY INFORMATION : Background The FAA received a report from the manufacturer of a quality escape, resulting in a life reduction of the LPT stage 5 air seal installed on certain PW4062 model turbofan engines. Subsequent investigation by the manufacturer revealed that insufficient cooling after heat treatment resulted in non-conformance to the design specifications. This non-conformance lowers the LCF capability in a section of the LPT stage 5 air seal that already has an LCF life limit, resulting in a reduction in the LCF life limit from 15,000 cycles to 8,240 cycles. This condition, if not addressed, could result in the uncontained release of the LPT stage 5 air seal, damage to the engine, and damage to the airplane. The FAA is issuing this AD to address the unsafe condition on these products. FAA’s Determination The FAA is issuing this AD because the agency has 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 removal and replacement of the LPT stage 5 air seal. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq. ) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause,’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. The FAA has found the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because no domestic operators use this product. It is unlikely that the FAA will receive any adverse comments or useful information about this AD from any U.S. operator. Accordingly, notice and opportunity for prior public comment are unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the foregoing reason, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days. Comments Invited The FAA invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under ADDRESSES . Include ‘‘Docket No. FAA–2022–0589; Project Identifier AD–2022–00376–E’’ at the beginning of your comments. The most helpful comments reference a specific portion of the final rule, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to https:// www.regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule.
