[Docket No. FAA-2024-0457; Project Identifier MCAI-2023-01207-T; Amendment 39-22790; AD 2024-14-09]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule.
 SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2022-02-10, which applied to certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. AD 2022-02-10 required replacement of certain titanium screws. Since the FAA issued AD 2022-02-10, affected parts have been found in other areas of certain Falcon 7X airplanes as well as in additional Falcon 7X airplanes. This AD continues to require the actions in AD 2022-02-10, adds other locations for screw replacement, and revises the applicability, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD is effective October 15, 2024. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 15, 2024.

SUPPLEMENTARY INFORMATION:  Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2022-02-10, 
                    ( print page 72967)
                    Amendment 39-21907 (87 FR 7025, February 8, 2022) (AD 2022-02-10). AD 2022-02-10 applied to certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. AD 2022-02-10 was prompted by MCAI originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 2021-0047, dated February 16, 2021 (EASA AD 2021-0047), to correct an unsafe condition. AD 2022-02-10 required replacement of certain titanium screws. The FAA issued AD 2022-02-10 to address failure of an affected screw installed in a critical location, possibly resulting in reduced structural integrity of the airplane. The NPRM published in the 
                    **Federal Register**
                     on March 6, 2024 (89 FR 15965). The NPRM was prompted by EASA AD 2023-0207, dated November 21, 2023 (also referred to as the MCAI). The MCAI states that since EASA issued AD 2021-0047, it was determined that affected parts have been installed in production in additional areas of certain Model FALCON 7X airplanes already included in the applicability of EASA AD 2021-0047. Additionally, it was determined that additional Model FALCON 7X airplanes were not included in the applicability of EASA AD 2021-0047. In the NPRM, the FAA proposed to continue to require the actions in AD 2022-02-10, add other locations for screw replacement, and revise the applicability, as specified in EASA AD 2023-0207. 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-2024-0457. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. 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 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. Material Incorporated by Reference Under 1 CFR Part 51 EASA AD 2023-0207 specifies procedures for replacing certain Decomatic titanium screws (including an inspection of the bore dimension and corrective actions (oversizing or repair)). The EASA AD also restricts installation of certain Decomatic titanium screws. Dassault Service Bulletin 7X-467, Revision 2, dated March 20, 2023, specifies procedures for additional work. 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

 According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. 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 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.
