SUPPLEMENTARY INFORMATION:
Discussion
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2019-0065, dated March 27, 2019
(``EASA AD 2019-0065'') (also referred to as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Airbus SAS Model A350-941 airplanes. The MCAI
states:
Results of new additional tests, performed on the current
diagonal struts fitted at fuselage frame (FR) 102 on A350-941
aeroplanes, determined that the capability of the affected parts is
below the expected design specifications.
This condition, if not corrected, could affect the structural
integrity of the rear cone of the fuselage.
To address this potential unsafe condition, Airbus designed new
diagonal struts (serviceable parts), approved by Airbus mod 108588,
and issued the [service bulletin] SB to provide instructions for the
in-service replacement of the affected parts.
For the reasons described above, this [EASA] AD requires
replacement of the affected parts at fuselage FR102 with serviceable
parts. This [EASA] AD also prohibits (re)installation of affected
parts.
Related IBR Material Under 1 CFR Part 51
EASA AD 2019-0065 describes procedures for replacing the original
diagonal struts at frame 102 with new, improved parts. 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 a 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 agency
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 EASA AD
2019-0065 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 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. As a result,
EASA AD 2019-0065 is incorporated by reference in the FAA final rule.
This AD, therefore, requires compliance with the provisions specified
in EASA AD 2019-0065, except for any differences identified as
exceptions in the regulatory text of this AD. Service information
specified in EASA AD 2019-0065 that is required for compliance with
EASA AD 2019-0065 is available on the internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2019-
0496.
FAA's Justification and Determination of the Effective Date
Since there are currently no domestic operators of this product,
notice and opportunity for public comment before issuing this AD are
unnecessary. In addition, for the reasons 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-2019-0496;
Product Identifier 2019-NM-055-AD'' at the beginning of your comments.
The FAA specifically invites comments on the overall regulatory,
economic, environmental, and energy aspects of this AD. 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 agency receives, without change,
to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you
provide. The FAA will also post a report summarizing each substantive
verbal contact the agency receives about this AD.
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:
Estimated Costs for Required Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
5 work-hours x $85 per hour = $425.... $37,500 $37,925
------------------------------------------------------------------------
[[Page 32259]]
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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes and
associated appliances to the Director of the System Oversight Division.
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;
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.
