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) 2018-19-
26, which applied to all Dassault Aviation Model MYSTERE-FALCON 200
airplanes. AD 2018-19-26 required revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive maintenance requirements and airworthiness limitations.
This AD continues to require 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. The FAA is issuing this AD to address the unsafe
condition on these products.

DATES: This AD is effective March 5, 2020.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 5,
2020.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of
November 5, 2018 (83 FR 49275, October 1, 2018).

SUPPLEMENTARY INFORMATION:

Discussion

The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union, has issued
EASA AD 2019-0153, dated July 3, 2019 (``EASA AD 2019-0153'') (also
referred to as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all Dassault Aviation
Model MYSTERE-FALCON 200 airplanes. You may examine the MCAI in the AD
docket on the internet at https://www.regulations.gov by searching for
and locating Docket No. FAA-2019-0857.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2018-19-26, Amendment 39-19427 (83 FR
49275, October 1, 2018) (``AD 2018-19-26''). AD 2018-19-26 applied to
all Dassault Aviation Model MYSTERE-FALCON 200 airplanes. The NPRM
published in the Federal Register on October 30, 2019 (84 FR 58070).
The NPRM was prompted by a determination that new or more restrictive
airworthiness limitations are necessary. The NPRM proposed to require
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 fatigue cracking, damage, and
corrosion in principal structural elements; such fatigue cracking,
damage, and corrosion could result in 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

Dassault Aviation has issued Chapter 5-40-00, Airworthiness
Limitations, Revision 18, dated January 15, 2019, of the Dassault
Falcon 200 Maintenance Manual. This service information describes
mandatory maintenance tasks that operators must perform at specified
intervals.
This AD also requires Chapter 5-40-00, Airworthiness Limitations,
Revision 17, dated December 20, 2017, of the Dassault Falcon 200
Maintenance Manual, which the Director of the Federal Register approved
for incorporation by reference as of November 5, 2018 (83 FR 49275,
October 1, 2018).
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 9 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 2018-19-26 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 FAA recognizes that this number may vary from operator to
operator. In the past, the FAA has estimated that this action takes 1
work-hour per airplane. 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. Therefore, the FAA estimates the total cost per
operator 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes and
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

The FAA has 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.
