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) 2020-04-
22, which applied to certain Dassault Aviation Model FALCON 2000EX
airplanes. AD 2020-04-22 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 2020-04-22 and also 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 March 30, 2021.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 30,
2021.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of May 4,
2020 (85 FR 17487, March 30, 2020).

SUPPLEMENTARY INFORMATION:

Discussion

The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0114, dated May 20, 2020 (EASA
AD 2020-0114) (also referred to as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
all Dassault Aviation Model FALCON 2000EX airplanes.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2020-04-22, Amendment 39-19858 (85 FR
17487, March 30, 2020) (AD 2020-04-22). AD 2020-04-22 applied to
certain Dassault Aviation Model FALCON 2000EX airplanes. The NPRM
published in the Federal Register on November 3, 2020 (85 FR 69522).
The NPRM was prompted by a determination that new or more restrictive
airworthiness limitations are necessary. The NPRM proposed to continue
to require the actions in AD 2020-04-22 and also require revising the
existing maintenance or inspection program, as applicable, to
incorporate additional new or more restrictive airworthiness
limitations, as specified in EASA AD 2020-0114.
The FAA is issuing this AD to address reduced structural integrity
of the airplane. See the MCAI for additional background information.

Comments

The FAA gave the public the opportunity to participate in
developing this final rule. The FAA received no comments on the NPRM or
on the determination of the cost to the public.

Conclusion

The FAA reviewed the relevant data and determined that air safety
and the public interest require adopting this final rule as proposed,
except for minor editorial changes. The FAA has determined that these
minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

EASA AD 2020-0114 describes new or more restrictive airworthiness
limitations for airplane structures and safe life limits.
This AD also requires Chapter 5-40, Airworthiness Limitations, DGT
113877, Revision 12, dated November 2018, of the Dassault Falcon 2000EX
Maintenance Manual, which the Director of the Federal Register approved
for incorporation by reference as of May 4, 2020 (85 FR 17487, March
30, 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 17 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 2020-04-22 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 revision
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.
