Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a 
report of defects on the piston hole associated with the O2 
saver feature that may prevent efficient deactivation of the 
O2 saver function. This AD requires amending the existing 
airplane flight manual (AFM) to incorporate a check and an operating 
limitation regarding 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 becomes effective September 16, 2021.
    The Director of the Federal Register approved the incorporation by

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA Emergency AD 2021-0202-E, dated 
September 9, 2021 (EASA Emergency AD 2021-0202-E) (also referred to as 
the MCAI), to correct an unsafe condition for all Dassault Aviation 
Model FALCON 7X airplanes. EASA subsequently issued EASA AD 2021-
0202R1, dated September 10, 2021 (EASA AD 2021-0202R1) to address an 
incorrect reference to a non-existing part number within the definition 
of the affected part.
    This AD was prompted by a report of plastic molding burrs and 
defects found on the piston hole associated with the O2 
saver feature during production of certain SAFRAN flightcrew oxygen 
masks. The O2 saver function allows the flightcrew to wear 
the oxygen mask with limited oxygen consumption to save oxygen by 
delivering it only when needed, either automatically in case of 
depressurization, or manually by switching the 100% or EMERG mode 
button. Defects on the piston hole may prevent efficient deactivation 
of the O2 saver function. The FAA is issuing this AD to 
address this condition, which could lead to 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.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0202R1 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. EASA AD 2021-0202R1 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.

FAA's Determination

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
described above. The FAA is issuing this AD after determining that the 
unsafe condition described previously is likely to exist or develop on 
other products of the same type design.

Requirements of This AD

    This AD requires accomplishing the actions specified in EASA AD 
2021-0202R1 described previously, except for any differences identified 
as exceptions in the regulatory text of this AD.
    EASA AD 2021-0202R1 requires operators to ``inform all flight 
crews'' of amendments to the AFM, and thereafter to ``operate the 
aeroplane accordingly.'' However, this AD does not specifically require 
those actions as they are already required by FAA regulations. FAA 
regulations require operators furnish to pilots any changes to the AFM 
(e.g., 14 CFR 121.137), and to ensure that pilots are familiar with the 
AFM (e.g., 14 CFR 91.505). As with any other training requirement, 
training on the updated AFM content is tracked by the operators and 
recorded in each pilot's training record, which is available for the 
FAA to review. FAA regulations also require pilots to follow the 
procedures in the existing AFM including all updates. 14 CFR 91.9 
requires that no person may operate a civil aircraft without complying 
with the operating limitations specified in the AFM. Therefore, 
including a requirement in this AD to operate the airplane according to 
the amended AFM would be redundant and unnecessary.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, 
EASA AD 2021-0202R1 is incorporated by reference in this AD. This AD 
requires compliance with EASA AD 2021-0202R1 in its entirety through 
that incorporation, except for any differences identified as exceptions 
in the regulatory text of this AD. Using common terms that are the same 
as the heading of a particular section in EASA AD 2021-0202R1 does not 
mean that operators need comply only with that section. For example, 
where the AD requirement refers to ``all required actions and 
compliance times,'' compliance with this AD requirement is not limited 
to the section titled ``Required Action(s) and Compliance Time(s)'' in 
EASA AD 2021-0202R1. Service information required by EASA AD 2021-
0202R1 for compliance will be available at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2021-0790 after this AD is 
published.

Interim Action

    The FAA considers this AD interim action. If final action is later 
identified, the FAA might consider further rulemaking then.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies foregoing notice and comment prior to adoption of this rule 
because failure to deactivate the O2

[[Page 51606]]

saver function could lead to inadequate oxygen supply to the flightcrew 
in case of decompression of the airplane or smoke or fire in the flight 
deck. Accordingly, notice and opportunity for prior public comment are 
impracticable and contrary to the public interest pursuant to 5 U.S.C. 
553(b)(3)(B).
    In addition, the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days, 
for the same reasons the FAA found good cause to forego notice and 
comment.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

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
                  Labor cost                      Parts cost        product          Cost on U.S. operators

1 work-hour x $85 per hour = $85..............              $0             $85  Up to $1,700.
----------------------------------------------------------------------------------------------------------------

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, and
    (2) Will not affect intrastate aviation in Alaska.
