SUPPLEMENTARY INFORMATION:
Discussion
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0126, dated June 3, 2020
(``EASA AD 2020-0126'') (also referred to as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct
[[Page 73402]]
an unsafe condition for all Airbus SAS Model A350-1041 airplanes.
This AD was prompted by a report that, during testing, wear was
found on the drive strut anti-rotation knuckles and LBA bushes on a
certain flap station. The FAA is issuing this AD to address wear and
corrosion damage in the primary structure, which could result in
detachment of the outer flap during flight and possible damage to or
reduced control of the airplane. See the MCAI for additional background
information.
Related Service Information Under 1 CFR Part 51
EASA AD 2020-0126 describes procedures for repetitive inspections
for wear or corrosion damage, or surface protection removal of the
drive strut anti-rotation knuckles and LBA bushes (which includes
measuring the gap between the LBA and the drive strut and re-greasing),
corrective action (including repair; applying a witness mark to the LBA
to monitor possible movement; applying grease; replacing the drive
strut and LBA; or turning and reinstalling the drive strut), and
inspection reports. 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 the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
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 MCAI
described previously, as incorporated by reference, except for any
differences identified as exceptions in the regulatory text of this AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA initially worked with Airbus and EASA to develop a
process to use certain EASA ADs as the primary source of information
for compliance with requirements for corresponding FAA ADs. The FAA has
since coordinated with other manufacturers and civil aviation
authorities (CAAs) to use this process. As a result, EASA AD 2020-0126
is incorporated by reference in this final rule. This AD, therefore,
requires compliance with EASA AD 2020-0126 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 the EASA AD 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 the
EASA AD. Service information specified in EASA AD 2020-0126 that is
required for compliance with EASA AD 2020-0126 is available on the
internet at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating
Docket No. FAA-2020-1019.
FAA's Justification and Determination of the Effective Date
Since there are currently no domestic operators of these products,
notice and opportunity for public comment before issuing this AD are
unnecessary. In addition, for the reason stated above, the FAA finds
that good cause exists for making this amendment effective in less than
30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and the FAA did not precede it by notice and opportunity for
public comment. The FAA invites you to send any written relevant data,
views, or arguments about this AD. Send your comments to an address
listed under the ADDRESSES section. Include ``Docket No. FAA-2020-1019;
Product Identifier 2020-NM-104-AD'' at the beginning of your comments.
The most helpful comments reference a specific portion of the proposal,
explain the reason for any recommended change, and include supporting
data. 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 consider all comments received by the closing
date and may amend this AD based on those comments.
The FAA will post all comments the FAA receives, without change, to
<a href="https://www.regulations.gov">https://www.regulations.gov</a>, including any personal information you
provide. The FAA will also post a report summarizing each substantive
verbal contact the FAA receives about this AD.
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
Kathleen Arrigotti, Aerospace Engineer, Large Aircraft Section,
International Validation Branch, FAA, 2200 South 216th St., Des Moines,
WA 98198; telephone and fax 206-231-3218; email
<a href="/cdn-cgi/l/email-protection#741f15001c1811111a5a1506061d131b00001d341215155a131b02"><span class="__cf_email__" data-cfemail="660d07120e0a030308480714140f010912120f2600070748010910">[email protected]</span></a>. Any commentary that the FAA receives which
is not specifically designated as CBI will be placed in the public
docket for this rulemaking.
Interim Action
The FAA considers this AD interim action. If final action is later
identified, the FAA might consider further rulemaking then.
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:
[[Page 73403]]
Estimated Costs for Required Actions *
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
5 work-hours x $85 per hour = $425 $0 $425 per inspection.
per inspection.
------------------------------------------------------------------------
* Table does not include estimated costs for reporting.
The FAA estimates that it takes about 1 work-hour per product to
comply with the reporting requirement in this AD. The average labor
rate is $85 per hour. Based on these figures, the FAA estimates the
cost of reporting the inspection results on U.S. operators to be $85
per product.
The FAA has received no definitive data on which to base the cost
estimates for the on-condition actions specified in this AD.
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 operators. The FAA does not control warranty coverage for
affected operators. As a result, the FAA has included all known costs
in our cost estimate.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to
Information Collection Clearance Officer, Federal Aviation
Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.
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.

procedures or tests that are not identified as RC are recommended.
Those procedures and tests that are not identified as RC may be
deviated from using accepted methods in accordance with the
operator's maintenance or inspection program without obtaining
approval of an AMOC, provided the procedures and tests identified as
RC can be done and the airplane can be put back in an airworthy
condition. Any substitutions or changes to procedures or tests
identified as RC require approval of an AMOC.
(4) Paperwork Reduction Act Burden Statement: A federal agency
may not conduct or sponsor, and a person is not required to respond
to, nor shall a person be subject to a penalty for failure to comply
with a collection of information subject to the requirements of the
Paperwork Reduction Act unless that collection of information
displays a current valid OMB Control Number. The OMB Control Number
for this information collection is 2120-0056. Public reporting for
this collection of information is estimated to be approximately 1
hour per response, including the time for reviewing instructions,
searching existing data sources, gathering and maintaining the data
needed, and completing and reviewing the collection of information.
All responses to this collection of information are mandatory as
required by this AD. Send comments regarding this burden estimate or
any other aspect of this collection of information, including
