Airworthiness Directives; Dassault Aviation Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directives (ADs) 2016-01-
16, 2017-19-03, and 2018-19-05, which applied to Dassault Aviation
Model MYSTERE-FALCON 900 airplanes. Those ADs require revising the
maintenance or inspection program, as applicable, to incorporate new or
more restrictive maintenance requirements and/or airworthiness
limitations. This AD requires revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations. Since AD 2018-19-05 was issued,
the FAA has determined 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 January 13, 2020.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 13,
2020.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of
October 26, 2018 (83 FR 47813, September 21, 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 2019-0132, dated June 11, 2019 (also referred to as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for all Dassault Aviation Model MYSTERE-
FALCON 900 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-2019-0668.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2018-19-05, Amendment 39-19405 (83 FR
47813, September 21, 2018) (``AD 2018-19-05''). AD 2018-19-05 applied
to all Dassault Aviation Model MYSTERE-FALCON 900 airplanes. AD 2018-
19-05 specified that accomplishing the actions required by paragraph
(g) of that AD terminated the requirements of AD 2016-01-16, Amendment
39-18376 (81 FR 3320, January 21, 2016) (``AD 2016-01-16''); and AD
2017-19-03, Amendment 39-19033 (82 FR 43166, September 14, 2017) (``AD
2017-19-03''). Therefore, this AD also supersedes AD 2016-01-16 and AD
2017-19-03. Additionally, AD 2018-19-05 specified that accomplishing
the actions required by paragraph (g) of that AD terminated the
requirements of paragraph (g)(1) of AD 2010-26-05, Amendment 39-16544
(75 FR 79952, December 21, 2010), for Dassault Aviation Model MYSTERE-
FALCON 900 airplanes, which is specified in paragraph (k) of this AD.
The NPRM published in the Federal Register on September 11, 2019
(84 FR 47906). 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
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, Airworthiness
Limitations, Revision 24, dated September 2018, of the Dassault
Aviation Falcon 900 Maintenance Manual. This service information describes
procedures, maintenance tasks, and airworthiness limitations specified in the
Airworthiness Limitations Section (ALS) of the airplane maintenance
manual (AMM).
This AD also requires Chapter 5-40, Airworthiness Limitations,
Revision 23, dated September 2017, of the Dassault Aviation Falcon 900
Maintenance Manual, which the Director of the Federal Register approved
for incorporation by reference as of October 26, 2018 (83 FR 47813,
September 21, 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 134 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 2018-19-05 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 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. 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.
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 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.
