ACTION: Final rule.
Discussion
The FAA is adopting a new
airworthiness directive (AD) for all
Airbus SAS Model A350–941 and –1041
airplanes. This AD was prompted by
reports of cracks within the ring gears of
a slat geared rotary actuator (SGRA)
resulting from a change in the raw
material manufacturing process. This
AD requires replacement of affected
parts with serviceable parts, as specified
in a European Aviation Safety Agency
(EASA) AD, which is incorporated by
reference. The FAA is issuing this AD
to address the unsafe condition on these
products.
DATES: This AD is effective November
14, 2019.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of November 14, 2019.
ADDRESSES: For the material
incorporated by reference (IBR) in this
AD, contact the EASA, KonradAdenauer-Ufer 3, 50668 Cologne,

The EASA, which is the Technical
Agent for the Member States of the
European Union, has issued EASA AD
2019–0020, dated January 31, 2019
(‘‘EASA AD 2019–0020’’) (also referred
to as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for all Airbus SAS Model A350–941 and
–1041 airplanes.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all Airbus SAS Model A350–
941 and –1041 airplanes. The NPRM
published in the Federal Register on
April 9, 2019 (84 FR 14038). The NPRM
was prompted by reports of cracks
within the ring gears of an SGRA
resulting from a change in the raw
material manufacturing process. The
NPRM proposed to require replacement
of affected parts with serviceable parts.
The FAA is issuing this AD to address
cracking of SGRA ring gears. This
condition, if not detected and corrected,
could, in combination with an
independent failure on the second
SGRA of the same slat surface, lead to
detachment of the slat surface, possibly
resulting in reduced control of the
airplane and injury to persons on the
ground. See the MCAI for additional
background information.

Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The following presents
the comments received on the NPRM
and the FAA’s response to each
comment.
Support for the NPRM
The Air Line Pilots Association,
International; Stephanie Lok; and an
anonymous commenter indicated their
support for the NPRM.
Request To Clarify Requirements for
Group 1 Airplanes
Delta Air Lines (Delta) requested that
a statement be added to paragraph (g) of
this AD to clarify that the installation of
affected parts was prohibited for Group
1 airplanes before 15,000 flight hours.
Delta asserted that the AD could be
interpreted as allowing the installation
of affected parts on those airplanes
during that time period.
The FAA does not agree that an
additional statement to paragraph (g) of
this AD is necessary. The FAA has
confirmed with EASA that since the
safety assessment was performed on the
life of the airplane and not the life of the
affected part, a restriction to limit the
affected parts prior to 15,000 flight
hours is not necessary. Therefore, the
commenter’s interpretation that
installation of affected parts could be
allowed prior to 15,000 flight hours is
correct. This AD has not been changed
in this regard.
Request To Modify Serial Number
Table
Delta requested that the serial
numbers of final assembly line units be
removed from Table 1 of certain
Liebherr service information instead of
noting that they are to be excluded.
The FAA does not agree with the
commenter’s request. Although the
proposal may provide a more
straightforward presentation of the
serial numbers, obtaining new service
information with revised serial number
tables from the manufacturer would
delay publication of this AD. This delay
would be inappropriate since the FAA
has determined that an unsafe condition
exists and that the required actions must
be accomplished to ensure continued
safety. The FAA also has determined
that the serial number table in the
Liebherr service information provides
the information necessary to comply
with this AD. Therefore, this AD has not
been changed in this regard.

Request To Clarify Location of
Identification Mark
Delta requested that certain Airbus
service information be updated to
clarify the location of a certain marking
on the identification plate. Delta noted
that the Liebherr service information
refers to the specified marking, but does
not show the marking’s location, while
the Airbus service information does not
refer to the marking at all.
The FAA disagrees with obtaining
revised service information because it
would delay publication of this AD,
which would be inappropriate for the
reasons stated previously. However, the
FAA agrees to clarify the location of the
specified marking on the identification
plate. The FAA has confirmed with
EASA that the marking will be on both
‘‘A’’ faces of the identification plate, as
depicted in Figure 1 of the Liebherr
service information. This AD has not
been changed in this regard.
Conclusion
The FAA reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this
final rule as proposed, except for minor
editorial changes. The FAA has
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
Related IBR Material Under 1 CFR Part
51
EASA AD 2019–0020 describes
procedures for replacing the affected
SGRAs. 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 12 airplanes of U.S. registry. The
FAA estimates the following costs to
comply with this AD:
ESTIMATED COSTS FOR REQUIRED ACTIONS
Labor cost
Parts cost
Cost per
product
Cost on U.S.
operators
25 work-hours × $85 per hour = $2,125 .....................................................................................
(*) $
* $2,125
* $25,500
* The FAA has received no definitive data that would enable the agency to provide cost estimates for the parts 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
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
VerDate Sep<11>2014
16:03 Oct 09, 2019
Jkt 250001
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
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.

Airbus service information does not refer to the marking at all.
The FAA disagrees with obtaining revised service information
because it would delay publication of this AD, which would be
inappropriate for the reasons stated previously. However, the FAA
agrees to clarify the location of the specified marking on the
identification plate. The FAA has confirmed with EASA that the marking
will be on both ``A'' faces of the identification plate, as depicted in
Figure 1 of the Liebherr service information. This AD has not been
changed in this regard.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule as proposed, except for minor
editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

SGRAs. 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 12 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.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
25 work-hours x $85 per hour = $2,125........................ (*) $ * $2,125 * $25,500
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data that would enable the agency to provide cost estimates for the parts
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 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
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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2019-19-14 Airbus SAS: Amendment 39-19750; Docket No. FAA-2019-0194;
Product Identifier 2019-NM-009-AD.
(a) Effective Date
This AD is effective November 14, 2019.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Airbus SAS Model A350-941 and -1041
airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of America Code 27, Flight
controls.
(e) Reason
This AD was prompted by reports of cracks within the ring gears
of a slat geared rotary actuator (SGRA), resulting from a change in
the raw material manufacturing process. The FAA is issuing this AD
to address cracking of SGRA ring gears. This condition, if not
detected and corrected, could, in combination with an independent
failure on the second SGRA of the same slat surface, lead to
detachment of the slat surface, possibly resulting in reduced
control of the airplane and injury to persons on the ground.
[[Page 54492]]
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in
accordance with, European Aviation Safety Agency (EASA) AD 2019-
0020, dated January 31, 2019 (``EASA AD 2019-0020'').
(h) Exceptions to EASA AD 2019-0020
(1) For purposes of determining compliance with the requirements
of this AD: Where EASA AD 2019-0020 refers to its effective date,
this AD requires using the effective date of this AD.
(2) The ``Remarks'' section of EASA AD 2019-0020 does not apply
to this AD.
(i) Other FAA AD Provisions
The following provisions also apply to this AD:

approved AMOC, notify your appropriate principal inspector, or
lacking a principal inspector, the manager of the local flight
standards district office/certificate holding district office.
(2) Contacting the Manufacturer: For any requirement in this AD
to obtain instructions from a manufacturer, the instructions must be
accomplished using a method approved by the Manager, International
Section, Transport Standards Branch, FAA; or EASA; or Airbus SAS's
EASA Design Organization Approval (DOA). If approved by the DOA, the
approval must include the DOA-authorized signature.
(3) Required for Compliance (RC): For any service information
referenced in EASA AD 2019-0020 that contains RC procedures and
tests: Except as required by paragraph (i)(2) of this AD, RC
procedures and tests must be done to comply with this AD; any
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
