89 Fed. Reg. 15965 (Mar. 6, 2024)

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to supersede Airworthiness Directive (AD) 2022–02–10, which applies to certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. AD 2022–02–10 requires 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 proposed AD would continue to require the actions in AD 2022–02–10, add other locations for screw replacement, and revise the applicability, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). 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 April 22, 2024.

Background

The FAA issued AD 2022–02–10, Amendment 39–21907 (87 FR 7025, February 8, 2022) (AD 2022–02–10), for 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, to correct an unsafe condition.

AD 2022–02–10 requires 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. See the MCAI for additional background information.

Actions Since AD 2022–02–10 Was Issued

Since the FAA issued AD 2022–02–10, EASA superseded EASA AD 2021– 0047, dated February 16, 2021, and issued EASA AD 2023–0207, dated November 21, 2023 (also referred to as the MCAI), to correct an unsafe condition for certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. 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.

The FAA is proposing 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.

Explanation of Retained Requirements

Although this proposed AD does not explicitly restate the requirements of AD 2022–02–10, this proposed AD would retain all of the requirements of AD 2022–02–10. Those requirements are referenced in EASA AD 2023–0207, which, in turn, is referenced in paragraph (g) of this proposed AD.

Related Service Information Under 1 CFR Part 51

EASA AD 2023–0207 specifies procedures for replacing 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 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 this 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 retain certain requirements of AD 2022–02–10. This proposed AD would require accomplishing the actions specified in EASA AD 2023–0207 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 2023–0207 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2023–0207 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 2023–0207 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 2023–0207. Service information required by EASA AD 2023–0207 for compliance will be available at regulations.gov under Docket No. FAA–2024–0457 after the FAA final rule is published.

Costs of Compliance

The FAA estimates that this AD, if adopted as proposed, would affect 44 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:

Estimated Costs for Required Actions

Action Labor cost Parts cost Cost per product Cost on U.S. operators
Retained actions from AD 2022–02–10 Up to 90 work-hours × $85 per hour = $7,650 $0 Up to $7,650 Up to $336,600.
New proposed requirements Up to 110 work-hours × $85 per hour = $9,350 0 Up to $9,350 Up to $411,400.

According to the manufacturer, some or all of the costs of this proposed 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

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.
