Background 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 A350-941 and -1041 airplanes. The NPRM published in the Federal Register on December 15, 2022 (87 FR 76589). The NPRM was prompted by AD 2022-0186, dated September 13, 2022, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2022-0186) (also referred to as the MCAI). The MCAI states that an in-service inspection found OHSC crash rods that were disconnected. The investigation conducted by the manufacturer determined that this incorrect installation was due to human error in the final assembly line. This condition, if not corrected, could affect the structural integrity of the OHSC under emergency landing loads, which could lead to OHSC detachment, resulting in injury to occupants and blocking an escape path during an emergency evacuation. In the NPRM, the FAA proposed to require a one-time detailed inspection of the OHSC crash rods and, depending on findings, corrective actions, as specified in EASA AD 2022-0186. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2022-1582. Discussion of Final Airworthiness Directive Comments The FAA received comments from one commenter who supported the NPRM without change. Conclusion 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 this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data, considered the comment received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. 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. Related Service Information Under 1 CFR Part 51 EASA AD 2022-0186 specifies procedures for a one-time detailed inspection for any defect ( i.e., OHSC crash rod is disconnected or the quick connections are unlocked) of the OHSC crash rods, and, depending on findings, corrective actions ( i.e., installation or locking of the quick connections on the OHSC crash rods). The FAA also reviewed Airbus Service Bulletin A350-53-P074, dated July 29, 2022, which identifies the affected manufacturer serial numbers. 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 ADDRESSES . Costs of Compliance The FAA estimates that this AD affects 30 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: Estimated Costs for Required Actions Labor cost Parts cost Cost per product Cost on U.S. operators 6 work-hours × $85 per hour = $510 $0 $510 $15,300 The FAA estimates the following costs to do any necessary on-condition action that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need this on-condition action: Estimated Costs of On-Condition Actions Labor cost Parts cost Cost per product 2 work-hours × $85 per hour = $170 $4 $174 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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. For the reasons discussed above, I certify that this AD: (1) Is not a "significant regulatory action" under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) 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. 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 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2023-03-17 Airbus SAS: Amendment 39-22342; Docket No. FAA-2022-1582; Project Identifier MCAI-2022-01232-T. (a) Effective Date This airworthiness directive (AD) is effective April 7, 2023. (b) Affected ADs None.
