Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-21-
20, which applied to certain Dassault Aviation Model FALCON 900EX 
airplanes. AD 2020-21-20 required revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive maintenance requirements and/or 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 2020-21-20 and requires revising the existing 
maintenance or inspection program, as applicable, to incorporate 
additional new or more restrictive airworthiness limitations; as 
specified in 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 May 12, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 12, 
2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
December 7, 2020 (85 FR 69144, November 2, 2020).

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2020-21-20, Amendment 39-21293 (85 FR 
69144, November 2, 2020) (AD 2020-21-20). AD 2020-21-20 applied to 
certain Dassault Aviation Model FALCON 900EX airplanes. AD 2020-21-20 
required revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive maintenance 
requirements and/or airworthiness limitations. The FAA issued AD 2020-
21-20 to address, among other things, fatigue cracking and damage in 
principal structural elements; such fatigue cracking and damage could 
result in reduced structural integrity of the airplane. AD 2020-21-20 
specifies that accomplishing the actions required by paragraph (g) or 
(i) of that AD terminates the requirements of paragraph (g)(1) of AD 
2010-26-05, Amendment 39-16544 (75 FR 79952, December 21, 2010) for 
Dassault Aviation Model FALCON 900EX airplanes, serial number (S/N) 97 
and S/Ns 120 and higher. This AD therefore continues to allow that 
terminating action.
    The NPRM published in the Federal Register on November 18, 2022 (87 
FR 69214). The NPRM was prompted by AD 2022-0141, dated July 7, 2022, 
issued by EASA (EASA AD 2022-0141) (referred to after this 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 AD

[[Page 20739]]

2020-21-20. The NPRM 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 EASA AD 2022-0141.
    The FAA is issuing this AD 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. You may examine the MCAI in the AD docket at 
regulations.gov under Docket No. FAA-2022-1473.

Discussion of Final Airworthiness Directive

Comments

    The FAA received one comment from an anonymous commenter. The 
following presents the comments received on the NPRM and the FAA's 
response to each comment.

Request To Clarify Reason for Proposed AD

    The commenter requested more detail, and clarification of why the 
FAA issued the proposed AD.
    The FAA agrees to clarify. EASA, which is the State of Design 
Authority for the affected airplanes, issued the MCAI to address an 
unsafe condition. The FAA reviewed the MCAI and concurred that an 
unsafe condition is likely to exist or develop in the affected 
airplanes. In order to require affected operators to accomplish the 
proposed actions, the FAA must issue an airworthiness directive. The 
FAA issued the proposed rule to provide interested parties the 
opportunities to provide feedback, which the FAA considered before 
issuing this AD. Once the AD is effective, operators must comply with 
the required actions specified in this AD to ensure the identified 
unsafe condition is addressed. The FAA did not change this AD as a 
result of this comment.

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, considered the 
comment 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 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 2022-0141. This service information 
specifies new or more restrictive airworthiness limitations for 
airplane structures and safe life limits.
    This AD also requires EASA AD 2020-0117, dated May 20, 2020, which 
the Director of the Federal Register approved for incorporation by 
reference as of December 7, 2020 (85 FR 69144, November 2, 2020).
    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 191 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 2020-21-20 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.
