Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-22-
13, which applied to certain Dassault Aviation Model FALCON 7X
airplanes. AD 2023-22-13 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 certain actions in AD 2023-
22-13 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 (IBR). 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 a certain publication listed in this AD as of October 15,
2024.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of
December 29, 2023 (88 FR 82246, November 24, 2023).

ADDRESSES:
AD Docket: You may examine the AD docket at regulations.gov under
Docket No. FAA-2024-1290; or in person at Docket Operations between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket contains this final rule, the mandatory continuing airworthiness
information (MCAI), any comments received, and other information. The

SUPPLEMENTARY INFORMATION:

Background

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2023-22-13, Amendment 39-22597 (88 FR
82246, November 24, 2023) (AD 2023-22-13), AD 2023-22-13 applied to
certain Dassault Aviation Model FALCON 7X airplanes. AD 2023-22-13
required revising the existing maintenance or inspection program, as
applicable, to incorporate new or more restrictive airworthiness
limitations. The FAA issued AD 2023-22-13 to address reduced structural
integrity and reduced control of the airplane due to the failure of
system components. AD 2023-22-13 specifies that accomplishing the
revision required by that AD terminates certain requirements of AD
2014-16-23, Amendment 39-17947 (79 FR 52545, September 4, 2014) (AD
2014-16-23). This AD therefore continues to allow that terminating
action.
The NPRM published in the Federal Register on May 13, 2024 (89 FR
41361). The NPRM was prompted by AD 2024-0033, dated January 31, 2024,
issued by EASA, which is the Technical Agent for the Member States of
the European Union, (EASA AD 2024-0033) (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 certain
actions in AD 2023-22-13 and to require revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitations, as specified in EASA AD
2024-0033. The FAA is issuing this AD to address reduced structural
integrity and reduced control of the airplane due to the failure of
system components.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2024-1290.

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 Material Under 1 CFR Part 51

The FAA reviewed EASA AD 2024-0033. This material specifies new or
more restrictive airworthiness limitations for airplane structures and
safe life limits.
This AD also requires EASA AD 2023-0063, dated March 20, 2023,
which the Director of the Federal Register approved for incorporation
by reference as of December 29, 2023 (88 FR 82246, November 24, 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 134 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 2023-22-13 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.
