14 CFR Part 39

[Docket No. FAA-2022-0604; Project Identifier MCAI-2021-01375-T; 
Amendment 39-22148; AD 2022-17-10]

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) 2021-19-
20, which applied to all Dassault Aviation Model FALCON 7X airplanes. 
AD 2021-19-20 required amending the existing airplane flight manual 
(AFM) to incorporate a check and an operating limitation regarding the 
O2 saver function. This AD was prompted by reports of 
defects that may prevent efficient deactivation of the O2 
saver function of crew oxygen masks and a determination that the AFM 
amendment required by AD 2021-19-20 may not be sufficient to mitigate 
the risk. This AD retains the requirements of AD 2021-19-20 and also 
requires physical deactivation of the O2 saver function, as 
specified in a European Union Aviation Safety Agency (EASA) AD, which 
is incorporated by reference. This AD also limits the installation of 
affected parts under certain conditions. The FAA is issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective October 27, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 27, 
2022.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0272, dated December 6, 2021 
(EASA AD 2021-0272) (also referred to as the MCAI), to correct an 
unsafe condition for all Dassault Aviation Model FALCON 7X airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2021-19-20, Amendment 39-21738 (86 FR 
51604, September 16, 2021) (AD 2021-19-20). AD 2021-19-20 applied to 
all Dassault Aviation Model FALCON 7X airplanes. The NPRM published in 
the Federal Register on June 9, 2022 (87 FR 35122). The NPRM was 
prompted by reports of defects on the piston hole associated with the 
O2 saver function that may prevent efficient deactivation of 
the O2 saver function and a determination that the AFM 
amendment required by AD 2021-19-20 may not be sufficient to mitigate 
the risk of failed deactivation of the O2 saver function. 
The NPRM proposed to retain the requirements of AD 2021-19-20 and 
require physical deactivation of the O2 saver function, as 
specified in EASA AD 2021-0272. The NPRM also proposed to limit the 
installation of affected parts under certain conditions.
    The FAA is issuing this AD to address defects that may prevent 
efficient deactivation of the O2 saver function, which could 
result in an inadequate oxygen supply to the flightcrew in case of 
decompression of the airplane or smoke or fire in the flight deck. See 
the MCAI for additional background information.

Discussion of Final Airworthiness Directive

Comments

    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 
requires adopting this AD as proposed. Except for minor editorial 
changes, this AD is adopted as proposed in the NPRM. None of the 
changes will increase the economic burden on any operator.

[[Page 57808]]

Accordingly, the FAA is issuing this AD to address the unsafe condition 
on these products.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0272 specifies procedures for amending the existing 
AFM to incorporate a specific check to ensure that the O2 
saver function is not activated and an operating limitation to prevent 
use of the O2 saver function; and for mechanically 
deactivating the O2 saver function of the affected parts 
(Safran flightcrew oxygen masks having part number MLD40-45-005 and 
serial number B150451 through B172005 inclusive without the letter 
``R'' after the serial number). EASA AD 2021-0272 also limits the 
installation of affected parts under certain conditions. 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 20 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                              Cost per          Cost on U.S.
              Action                      Labor cost         Parts cost        product           operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2021-19-   1 work-hour x $85 per              $0             $85  Up to $1,700.
 20.                                 hour = $85.
New actions.......................  4 work-hours x $85                  0             340  6,800.
                                     per hour = $340.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the cost estimate.

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.
