 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2022-0686; Project Identifier MCAI-2022-00088-T]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 airplanes. This proposed AD was prompted by a report indicating that the inflatable free aisle restrictor (IFAR) on certain single lane slide-rafts demonstrated inconsistent release behavior in aft wind conditions. This proposed AD would require replacing an affected part with a serviceable part, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
 DATES: The FAA must receive comments on this proposed 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:*

Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022-0013, dated January 25, 2022 (EASA AD 2022-0013) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A350-941 airplanes. This proposed AD was prompted by a report indicating that following the introduction of the IFAR system on single lane slide-rafts, the IFAR demonstrated inconsistent release behavior due to interference or entanglement of the upper part of the IFAR with the slide-raft cover or door structure in aft wind conditions. These affected slide-rafts are installed at passenger door 3, left-hand and right-hand sides. The FAA is proposing this AD to address inconsistent release of single lane slide-rafts having the IFAR system, which if not corrected, could result in a slide-raft being unusable during an emergency and impair the safe evacuation of occupants. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2022-0013 specifies procedures for replacing escape slide-rafts having certain part numbers (affected parts) with serviceable parts (which includes parts that have been modified and re-identified). EASA AD 2022-0013 also prohibits the installation of affected parts on any airplane. 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. FAA's Determination This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in EASA AD 2022-0013 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. This proposed AD would also prohibit the installation of affected parts. Explanation of Required Compliance Information In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate EASA AD 2022-0013 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2022-0013 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2022-0013 does not mean that operators need comply only with that section. For example, where the AD requirement refers to “all required actions and compliance times,” compliance with this AD requirement is not limited to the section titled “Required Action(s) and Compliance Time(s)” in EASA AD 2022-0013. Service information required by EASA AD 2022-0013 for compliance will be available at 
                    *https://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2022-0686 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD would affect 30 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:
                    ( print page 36420) Estimated Costs for Required Actions
Labor cost
Parts cost
Cost per
                             product
Cost on U.S.
                             operatorsUp to 11 work-hours × $85 per hour = Up to $935
$400
Up to $1,335
Up to $40,050.
 According to the manufacturer, some or all of the costs of this proposed AD maybe covered under warranty, thereby reducing the cost impact on affected operators. The FAA does not control warranty coverage for affected operators. As a result, the FAA has included all known costs in the cost estimate. 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 The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a “significant regulatory action” under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
