Abstract
The FAA is superseding Airworthiness Directive (AD) 2023-22- 05, which applied to certain Dassault Aviation Model FAN JET FALCON and FAN JET FALCON SERIES C, D, E, F, and G airplanes. AD 2023-22-05 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-22-05, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023-22-05 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Dassault Aviation Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-22-
05, which applied to certain Dassault Aviation Model FAN JET FALCON and
FAN JET FALCON SERIES C, D, E, F, and G airplanes. AD 2023-22-05
required revising the existing maintenance or inspection program, as
applicable, to incorporate new or more restrictive airworthiness
limitations. Since the FAA issued AD 2023-22-05, the FAA has determined
that new or more restrictive airworthiness limitations are necessary.
This AD continues to require certain actions in AD 2023-22-05 and
requires revising the existing maintenance or inspection program, as
applicable, to incorporate new or more restrictive airworthiness
limitations. The FAA is issuing this AD to address the unsafe condition
on these products.
DATES: This AD is effective June 18, 2026.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of June 18,
2026.
The Director of the Federal Register approved the incorporation by
reference of a certain other publications listed in this AD as of
December 26, 2023 (88 FR 80570, November 20, 2023).

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2023-22-05, Amendment 39-22589 (88 FR
80570, November 20, 2023) (AD 2023-22-05). AD 2023-22-05 applied to
certain Dassault Aviation Model FAN JET FALCON and FAN JET FALCON
SERIES C, D, E, F, and G airplanes. AD 2023-22-05 required revising the
existing maintenance or inspection program, as applicable, to
incorporate new or more restrictive airworthiness limitations. The FAA
issued AD 2023-22-05 to address, among other things, fatigue cracking
and damage in principal structural elements. The unsafe condition, if
not addressed, could result in reduced structural integrity of the
airplane.
The NPRM was published in the Federal Register on February 6, 2026
(91 FR 5368). The NPRM was prompted by EASA AD 2025-0125, dated May 28,
[[Page 27194]]
2025; corrected June 3, 2025 (EASA AD 2025-0125) (also referred to as
the MCAI), issued by EASA, which is the Technical Agent for the Member
States of the European Union. 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 2023-22-05 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
2025-0125. The FAA is issuing this AD to address the unsafe condition
on these products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2026-0738.
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
These products have been approved by the civil aviation authority
of another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, that authority has notified the FAA of the unsafe condition
described in the MCAI referenced above. The FAA reviewed the relevant
data, considered any comments received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on these products. 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
The FAA reviewed EASA AD 2025-0125, which specifies new or more
restrictive airworthiness limitations for airplane structures and safe
life limits.
This AD also requires EASA AD 2023-0060, dated March 16, 2023,
which the Director of the Federal Register approved for incorporation
by reference as of December 26, 2023 (88 FR 80570, November 20, 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 32 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 2023-22-05 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.
