# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Final rule.

# SUMMARY:

The FAA is superseding Airworthiness Directive (AD) 2023-04-13, which applied to certain Dassault Aviation Model FALCON 2000EX airplanes. AD 2023-04-13 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2023-04-13 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations; 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 January 16, 2024.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of January 16, 2024.

The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of May 12, 2023 (88 FR 20741, April 7, 2023).

# SUPPLEMENTARY INFORMATION:

## Background

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2023-04-13, Amendment 39-22360 (88 FR 20741, April 7, 2023) (AD 2023-04-13). AD 2023-04-13 applied to certain Dassault Aviation Model FALCON 2000EX airplanes. AD 2023-04-13 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA issued AD 2023-04-13 to address reduced structural integrity of the airplane. AD 2023-04-13 specifies that accomplishing the revision required by paragraph (g) or (j) of that AD terminates the requirements of paragraph (g)(1) of AD 2010-26-05, Amendment 39-16544 (75 FR 79952, December 21, 2010), for Dassault Aviation Model FALCON 2000EX airplanes. This AD therefore continues to allow that terminating action.

                    The NPRM published in the                     **Federal Register**                     on August 29, 2023 (88 FR 59476). The NPRM was prompted by AD 2023-0100, dated May 11, 2023, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2023-0100) (also referred to as the MCAI). The MCAI states that new or more restrictive airworthiness limitations have been developed.                

In the NPRM, the FAA proposed to continue to require the actions in AD 2023-04-13. The NPRM also proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in EASA AD 2023-0100. The FAA is issuing this AD to address reduced structural integrity of the airplane.

                    You may examine the MCAI in the AD docket at                     *regulations.gov*                     under Docket No. FAA-2023-1721.                

## 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.

## Related Service Information Under 1 CFR Part 51

EASA AD 2023-0100 specifies new or more restrictive airworthiness limitations for airplane structures and safe life limits.

This AD also requires EASA AD 2022-0136, dated July 6, 2022, which the Director of the Federal Register approved for incorporation by reference as of May 12, 2023 (88 FR 20741, April 7, 2023).

                    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.                

## Costs of Compliance

The FAA estimates that this AD affects 245 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

The FAA estimates the total cost per operator for the retained actions from AD 2023-04-13 to be $7,650 (90 work-hours × $85 per work-hour).

The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 work-hours per operator, although the agency recognizes that this number may vary from operator to operator. In the past, the agency has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate.

The FAA estimates the total cost per operator for the new actions to be $7,650 (90 work-hours × $85 per work-hour).

## 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.
