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) 2019-03-
27, which applied to all Dassault Aviation Model Falcon 10 airplanes. 
AD 2019-03-27 required repetitive detailed inspections of certain wing 
anti-ice outboard flexible hoses, and replacement of certain wing anti-
ice outboard flexible hoses. This AD continues to require the actions 
in AD 2019-03-27, and also adds a new life limit for the improved wing 
anti-ice flexible hose; as specified in a European Union Aviation 
Safety Agency (EASA) AD, which is incorporated by reference. This AD 
was prompted by a report indicating that certain wing anti-ice outboard 
flexible hoses were found damaged, likely resulting from the 
installation process, and the development of an improved wing anti-ice 
flexible hose. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective March 31, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 31, 
2021.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0127, dated June 4, 2020 (EASA 
AD 2020-0127) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Dassault Aviation Model Falcon 10 airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2019-03-27, Amendment 39-19579 (84 FR 7801, 
March 5, 2019) (AD 2019-03-27). AD 2019-03-27 applied to all Dassault 
Aviation Model Falcon 10 airplanes. The NPRM published in the Federal 
Register on November 2, 2020 (85 FR 69269). The NPRM was prompted by a 
report indicating that certain wing anti-ice outboard flexible hoses 
were found damaged, likely resulting from the installation process, and 
the development of an improved wing anti-ice flexible hose. The NPRM 
proposed to continue to require the actions in AD 2019-03-27, as 
specified in an EASA AD. The NPRM also proposed to require adding a new 
life limit for the improved wing anti-ice flexible hose, as specified 
in EASA AD 2020-0127.
    The FAA is issuing this AD to address damaged wing anti-ice 
outboard flexible hoses, which could lead to a loss of performance of 
the wing anti-ice protection system that is not annunciated to the 
pilot, and could result in reduced control 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 2020-0127 describes procedures for repetitive detailed 
inspections of certain wing anti-ice outboard flexible hoses, 
replacement of certain wing anti-ice outboard flexible hoses, a new 
life limit for certain wing anti-ice outboard flexible hoses, and 
optional terminating actions for the repetitive inspections 
(replacement of all damaged affected wing anti-ice outboard flexible 
hoses or accomplishing and passing an inspection on an affected wing 
anti-ice outboard flexible hose after it has accumulated 100 flight 
cycles since installation on an airplane). 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 54 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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

    The FAA estimates the following costs to do any necessary on-
condition replacements that would be required based on the results of 
any required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition replacements:

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.
