Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-03-
19, which applied to certain Dassault Aviation Model MYSTERE-FALCON 20-
C5, 20-D5, 20-E5, and 20-F5 airplanes. AD 2020-03-19 required revising 
the existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations. This AD 
continues to require the actions in AD 2020-03-19 and requires revising 
the existing maintenance or inspection program, as applicable, to 
incorporate additional new or more restrictive airworthiness 
limitations; as specified in a European Union Aviation Safety Agency 
(EASA) AD, which is incorporated by reference. This AD was prompted by 
a determination that new or more restrictive airworthiness limitations 
are necessary. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective November 2, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 2, 
2023.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2020-03-19, Amendment 39-19843 (85 FR 
11280, February 27, 2020) (AD 2020-03-19). AD 2020-03-19 applied to 
certain Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 
20-F5 airplanes. AD 2020-03-19 required revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations. The FAA issued AD 2020-03-
19 to address fatigue cracking, damage, and corrosion in principal 
structural elements, which could result in reduced structural integrity 
of the airplane.
    The NPRM published in the Federal Register on July 11, 2023 (88 FR 
44065). The NPRM was prompted by EASA AD 2023-0058, dated March 16, 
2023, issued by EASA, which is the Technical Agent for the Member 
States of the European Union (referred to after this as the MCAI). The 
MCAI states that new or more restrictive airworthiness limitations have 
been developed.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1403.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 2020-03-19. In the NPRM, the FAA also proposed to require revising 
the existing maintenance or inspection program, as applicable, to 
incorporate additional new or more restrictive airworthiness 
limitations, as specified in an EASA AD. The FAA is issuing this AD to 
address fatigue cracking, damage, and corrosion in principal structural 
elements. The unsafe condition, if not addressed, could result in 
reduced structural integrity of the airplane.

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 2023-0058. This service information 
specifies procedures for airworthiness limitations for safe life limits 
and certification maintenance requirements.
    This AD also requires Chapter 5-40-00, Airworthiness Limitations, 
of the Dassault Falcon 20 Retrofit 731 Maintenance Manual, Revision 13, 
dated January 1, 2019, which the Director of the Federal Register 
approved for incorporation by reference as of April 2, 2020 (85 FR 
11280, February 27, 2020).
    This service information 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 56 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 2020-03-19 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

    The FAA determined that 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.

    (2) Paragraph (3) of EASA AD 2023-0058 specifies revising ``the 
approved AMP'' within 12 months after its effective date, but this 
AD requires revising the existing maintenance or inspection program, 
as applicable, within 90 days after the effective date of this AD.
    (3) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA AD 2023-0058 is at the applicable 
``limitations'' as incorporated by the requirements of paragraph (3) 
of EASA AD 2023-0058, or within 90 days after the effective date of

    After the existing maintenance or inspection program has been 
revised as required by paragraph (i) of this AD, no alternative 
actions (e.g., inspections) and intervals are allowed unless they 
are approved as specified in the provisions of the ``Ref. 
Publications'' section of EASA AD 2023-0058.

(l) Terminating Action for Certain Actions in AD 2010-26-05

    Accomplishing the actions required by paragraph (g) or (i) of

International Validation Branch, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or responsible Flight Standards Office, as 
appropriate. If sending information directly to the International 
Validation Branch, send it to the attention of the person identified

appropriate principal inspector, or lacking a principal inspector, 
the manager of the responsible Flight Standards Office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, International 
Validation Branch, FAA; or EASA; or Dassault Aviation's EASA Design 
Organization Approval (DOA). If approved by the DOA, the approval 
must include the DOA-authorized signature.
