Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-04-
10, which applied to all Dassault Aviation Model MYSTERE-FALCON 900 
airplanes. AD 2023-04-10 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-
10, 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 February 7, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of February 7, 
2023.
    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 20743, April 7, 2023).

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2023-1502; or in person at Docket Operations between 9

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2023-04-10, Amendment 39-22357 (88 FR 
20743, April 7, 2023) (AD 2023-04-10). AD 2023-04-10 applied to all 
Dassault Aviation Model MYSTERE-FALCON 900 airplanes. AD 2023-04-10 
required revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive airworthiness 
limitations. The FAA issued AD 2023-04-10 to address reduced structural 
integrity of the airplane. AD 2023-04-10 specifies that accomplishing 
the revision required by that AD terminates the requirements of 
paragraph (g)(1) of AD 2010-26-05, Amendment 39-16544 (75 FR 79952, 
December 21, 2010) (AD 2010-26-05) for Dassault Aviation Model MYSTERE-
FALCON 900 airplanes only. This AD therefore continues to allow that 
terminating action.
    The NPRM published in the Federal Register on July 21, 2023 (88 FR 
47086); corrected August 14, 2023 (88 FR 54933). The NPRM was prompted 
by AD 2023-0046, dated March 2, 2023, issued by EASA, which is the 
Technical Agent for the Member States of the European Union (EASA AD 
2023-0046) (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 2023-04-10 and to require revising the existing maintenance or 
inspection program, as specified in EASA AD 2023-0046. 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-2023-1502.

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

    The FAA reviewed EASA AD 2023-0046. This service information 
specifies new or more restrictive airworthiness limitations for 
airplane structures and safe life limits.
    This AD also requires EASA AD 2022-0137, dated July 6, 2022, which 
the Director of the Federal Register approved for incorporation by 
reference as of May 12, 2023 (88 FR 20743, 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 151 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 2023-04-10 to be $7,650 (90 work-hours x $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. 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 x $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.
