SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued AD 2021-06-07, Amendment 39-21474 (86 FR 17512, 
April 5, 2021) (AD 2021-06-07), for certain Airbus SAS Model A330-200 
series and A330-300 series airplanes. AD 2021-06-07 was prompted by 
reports of cracked flexible hoses in the CAOS. AD 2021-06-07 required 
repetitive detailed inspections of the CAOS and replacement of affected 
parts if necessary. The FAA issued AD 2021-06-07 to address cracked 
CAOS hoses. This condition, if not addressed, could lead to oxygen 
leakage in the flexible hoses of the CAOS, which, in combination with 
in-flight depressurization or smoke evacuation procedure, could result 
in injury to occupants of the courier area.

Actions Since AD 2021-06-07 Was Issued

    Since the FAA issued AD 2021-06-07, improved flexible oxygen hoses 
have been developed and EASA and the FAA have determined that 
replacement of each affected part with a new flexible oxygen hose is 
necessary to address the unsafe condition.
    European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2021-0173, dated July 21, 2021 (EASA AD 2021-0173) (also 
referred to as the MCAI), to correct an unsafe condition for certain 
Airbus SAS Model A330-243, A330-322, and A330-343 airplanes. You may 
examine the MCAI in the AD docket at regulations.gov by searching for 
and locating Docket No. FAA-2022-1247.
    This AD was prompted by reports of cracked flexible hoses in the 
CAOS, and the development of, and the development of improved flexible 
oxygen hoses. The FAA is issuing this AD to address cracked CAOS hoses. 
This condition, if not addressed, could lead to oxygen leakage in the 
flexible hoses of the CAOS, which, in combination with in-flight 
depressurization or smoke evacuation procedure, could result in injury 
to occupants of the courier area. See the MCAI for additional 
background information.

[[Page 67352]]

Change to the Applicability of AD 2021-06-07

    The applicability of AD 2021-06-07 is Airbus SAS Model A330-201, -
202, -203, -223, -243, -301, -302, -303, -321, -322, -323, -341, -342, 
and -343 airplanes that were converted to freighter airplanes in 
accordance with FAA supplemental type certificate (STC) ST04038NY and 
STC ST04045NY. However, the applicability of this AD is limited to 
Model A330-243, -322, and -343 airplanes having manufacturer serial 
numbers 0116, 0127, 0231, 0600, 0610, 0709, 0777, and 0781. Due to a 
design change introduced during passenger-to-freighter conversion, 
airplanes converted in the future will not be affected by the 
identified unsafe condition.

Related Service Information Under 1 CFR Part 51

    Elbe Flugzeugwerke GmbH (EFW) has issued Service Bulletin EFW-SB-
35-0001, Revision 01, dated July 3, 2020; and Service Bulletin EFW-SB-
35-0002, Revision 01, dated June 22, 2020. This service information 
describes procedures for repetitive detailed inspections (including 
functional tests) of the CAOS to detect any leakage or damage 
(cracking) in the 32209-series oxygen distribution hoses installed in 
the courier area and in lavatory A, and replacement.
    EFW has also issued Service Bulletin EFW-SB-35-0003, dated January 
27, 2021; and Service Bulletin EFW-SB-35-0006, dated June 9, 2021. This 
service information describes procedures for modifying the CAOS by 
replacing the 32209-series oxygen distribution hoses with improved 
flexible oxygen hoses.
    This AD would also require Elbe Flugzeugwerke GmbH Service Bulletin 
EFW-SB-35-0001, dated March 8, 2019; and Elbe Flugzeugwerke GmbH 
Service Bulletin EFW-SB-35-0002, dated September 2, 2019, which the 
Director of the Federal Register approved for incorporation by 
reference as of April 20, 2021 (86 FR 17512, April 5, 2021).
    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.

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 the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
and service information referenced above. The FAA is issuing this AD 
because the FAA evaluated all pertinent information and determined the 
unsafe condition exists and 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 the service 
information described previously.

FAA's Justification and Determination of the Effective Date

    There are currently no domestic operators of these products. 
Accordingly, notice and opportunity for prior public comment are 
unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the 
forgoing reason(s), 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.

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2022-1247; Project Identifier MCAI-
2021-01066-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to 
Elizabeth Dowling, Aerospace Engineer, Mechanical Systems and 
Administrative Services Section, FAA, New York ACO Branch, 1600 Stewart 
Avenue, Suite 410, Westbury, NY 11590; telephone 516-228-7300; email [email protected]. Any commentary that the FAA receives which is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

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

    Currently, there are no affected U.S.-registered airplanes. If an 
affected airplane is imported and placed on the U.S. Register in the 
future, the FAA provides the following cost estimates to comply with 
this AD:

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

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