Start Preamble
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Notice of proposed rulemaking (NPRM).
SUMMARY:
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a determination that the surface protection is missing between certain aluminum brackets and the struts to which they are attached in the flight deck air distribution system. This proposed AD would require applying surface protection to the affected aluminum brackets and struts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). This proposed AD would also prohibit modifying an airplane using certain service information. 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 January 27, 2023.

Background
EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022-0119, dated June 21, 2022 (EASA AD 2022-0119) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus SAS Model A350-941 and -1041 airplanes.
This proposed AD was prompted by a determination that the surface protection is missing between certain aluminum brackets and the struts to which they are attached in the flight deck air distribution system. The affected parts were installed either in production through Airbus modification 109229 or 109230, or in-service through accomplishing the original issue of Airbus Service Bulletin A350-21-P031; or the original issue of Airbus Service Bulletin A350-21-P032. The FAA is proposing this AD to address missing aluminum bracket surface protection. This condition, if not corrected, could lead to rupture of the associated ducting, reducing the efficiency of the flight deck air distribution system, which, in combination with smoke in the flight deck, could result in impaired flightcrew capability to control the airplane. See the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
EASA AD 2022-0119 specifies procedures for applying surface protection to aluminum brackets and struts at frame (FR) 22 and FR 24, as applicable, in zone C2-2 forward section. EASA AD 2020-0119 also prohibits modifying an airplane using certain service information. 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
These products have been approved by the aviation authority of another country and are 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 2022-0119 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD.
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 2022-0119 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2022-0119 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 2022-0119 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 2022-0119. Service information required by EASA AD 2022-0119 for compliance will be available at regulations.gov by searching for and locating Docket No. FAA-2022-1580 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:
Estimated Costs for Required Actions
Labor cost Parts cost Cost per product Cost on U.S. operators 8 work-hours × $85 per hour = $680 $1,350 $2,030 $60,900 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: Start Printed Page 76162
(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.
