Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-03-
24, which applied to certain Dassault Aviation Model MYSTERE-FALCON 20-
C5, 20-D5, 20-E5, and 20-F5 airplanes. AD 2020-03-24 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 2020-03-24 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 November 8, 2023.

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2020-03-24, Amendment 39-19848 (85 FR 
11289, February 27, 2020) (AD 2020-03-24). AD 2020-03-24 applied to 
certain Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 
20-F5 airplanes. AD 2020-03-24 required revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations. The FAA issued AD 2020-03-
24 to address fatigue cracking, damage, and corrosion in principal 
structural elements, which could result in reduced structural integrity 
of the airplane. AD 2020-03-24 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), for Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 
airplanes on which the SSIP [Supplemental Structural Inspection Program 
(Dassault Service Bulletin 730)] has been embodied into the airplane's 
existing maintenance or inspection program only. This AD therefore 
continues to allow that terminating action.
    The NPRM published in the Federal Register on July 19, 2023 (88 FR 
46115). The NPRM was prompted by AD 2023-0062, dated March 20, 2023, 
issued by EASA, (EASA AD 2023-0062) (also referred to as the MCAI), 
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 the actions in 
AD 2020-03-24 and 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-
0062. The FAA is issuing this AD to address fatigue cracking, damage, 
and corrosion in principal structural elements, which could result in 
reduced structural integrity of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1495.

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 2023-0062 specifies new or more restrictive airworthiness 
limitations for airplane structures and safe life limits.
    This AD also requires Chapter 5-40-01, Airworthiness Limitations, 
of the Dassault Falcon 20 Retrofit 731 Maintenance Manual, Revision 10, 
dated January 1, 2019, which the Director of the Federal Register 
approved for incorporation by reference as of April 2, 2020 (85 FR 
11289, February 27, 2020).
    This material is reasonably available because the interested 
parties have access to it through their normal course

[[Page 68455]]

of business or by the means identified in the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 57 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 2020-03-24 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.
