Airworthiness Directives; Dassault Aviation Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and
20-F5 airplanes. This AD was prompted by a determination that new or
more restrictive airworthiness limitations are necessary. This AD
requires 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 the unsafe condition
on these products.

DATES: This AD is effective April 2, 2020.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 2,
2020.

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 2019-0200R1, dated August 29, 2019 (``EASA AD 2019-0200R1'')
(also referred to as the Mandatory Continuing Airworthiness
Information, or ``the MCAI''), to correct an unsafe condition for
certain Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and
20-F5 airplanes, except those on which the Supplemental Structural
Inspection Program (SSIP) (Dassault Service Bulletin 730) has been
embodied into the airplane's maintenance program. 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-2019-0868.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Dassault
Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes.
The NPRM published in the Federal Register on November 18, 2019 (84 FR
63585). 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, which 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, of the Dassault Falcon 20 Retrofit 731 Maintenance Manual,
Revision 13, dated January 1, 2019. This service information describes
procedures for airworthiness limitations for safe life limits and
certification maintenance requirements. 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 56 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD.
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 workhours 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.

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.
