(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Airbus SAS Model Airbus
A350–941 and A350–1041 airplanes.
This proposed AD was prompted by a
determination that the lower attachment
studs on the aft galley complex may be
installed incorrectly due to a missing
instruction in the maintenance
procedure task. This proposed AD
would require a one-time inspection of
the lower attachment studs on the aft
galley complex, and depending on
findings, accomplishment of applicable
corrective actions, as specified in a
European Union Aviation Safety Agency
(EASA) AD, which is proposed for
incorporation by reference (IBR). The
FAA is proposing this AD to address the
unsafe condition on these products.
DATES: The FAA must receive comments
on this proposed AD by September 3,
2024.
SUMMARY:
You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2024–0073,
dated March 18, 2024 (EASA AD 2024–
0073) (also referred to as the MCAI), to
correct an unsafe condition for certain
Airbus SAS Model Airbus A350–941
and A350–1041 airplanes. The MCAI
states that the maintenance procedure
task of the galley lower attachment stud
installation did not provide the required
maximum distance between the top of
the threaded sleeve and the top of the
threaded stud, which could lead to a
wrong installation of the lower
attachment stud having part number (P/
N) XP14–070–007800, P/N XP14–070–
019100, P/N XP14–070–005400, P/N
XP14–070–008400, and P/N XP14–070–
001100 on the aft galley complex. The
MCAI also states that the affected parts
are the lower attachment stud having
P/N XP14–070–007800, P/N XP14–070–
019100, P/N XP14–070–005400, P/N
XP14–070–008400, and P/N XP14–070–
001100 for which the as previously
described incomplete maintenance
procedure task has been accomplished
after the airplane date of manufacture
and before January 2024; and the lower
attachment stud P/N XP14–070–019100
which has been installed after the
airplane date of manufacture, and before
January 2024, in accordance with the
instructions of Airbus Alert Operators
Transmission A25P023–22, Revision 01,
dated September 27, 2022.
The FAA is proposing this AD to
address a possible wrong installation for
the lower attachment stud having part
number (P/N) XP14–070–007800, P/N
XP14–070–019100, P/N XP14–070–
005400, P/N XP14–070–008400, and
P/N XP14–070–001100 on the aft galley
complex. This condition, if not detected
and corrected, could lead to galley
module detachment, with possible
consequent injury to cabin crew and
passengers, and reduced evacuation
capacity from the airplane in case of an
emergency.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2024–1888.
Material Incorporated by Reference
Under 1 CFR Part 51
EASA AD 2024–0073 specifies a onetime installation inspection of the lower
attachment stud having P/N XP14–070–
007800, P/N XP14–070–019100, P/N
XP14–070–005400, P/N XP14–070–
008400, and P/N XP14–070–001100 on
the aft galley complex; and depending
on findings (the distance between the
top of the threaded sleeves and the top
of the threaded studs exceeds specified
limits), accomplishment of applicable
corrective actions (tightening the
applicable threaded studs).
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 ADDRESSES.
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 referenced above. The FAA
is issuing this NPRM after determining
that the unsafe condition described
previously is likely to exist or develop
in other products of the same type
design.
Proposed AD Requirements in This
NPRM
This proposed AD would require
accomplishing the actions specified in
EASA AD 2024–0073 described
previously, except for any differences
identified as exceptions in the
regulatory text of this proposed AD.
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, the FAA proposes to
incorporate EASA AD 2024–0073 by
reference in the FAA final rule. This
proposed AD would, therefore, require
compliance with EASA AD 2024–0073
in its entirety through that
incorporation, except for any differences
identified as exceptions in the
regulatory text of this proposed AD.
Using common terms that are the same
as the heading of a particular section in
EASA AD 2024–0073 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 2024–0073.
Material required by EASA AD 2024–
0073 for compliance will be available at
regulations.gov under Docket No. FAA–
2024–1888 after the FAA final rule is
published.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 32
airplanes of U.S. registry. The FAA
estimates the following costs to comply
with this proposed 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
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 this proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Would not affect intrastate
aviation in Alaska, and
(3) Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.

Background
The FAA has received three reports of
governor controller failures involving
Robinson Helicopter Model R22 Beta
and R44 II helicopters. These failures
resulted in three underspeed or
overspeed events, and two of these
events resulted in hard landings which
caused significant damage to the
helicopters. Each of these separate
incidents occurred after significant
rainfall where the helicopter was
exposed to those weather conditions.
Prior to these governor controller
failures, several operators notified
Robinson Helicopter of a malfunction of
the governor controller. Subsequent
investigation revealed evidence of water

Airworthiness Directives; Airbus SAS Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Airbus SAS Model Airbus A350-941 and A350-1041 airplanes.
This proposed AD was prompted by a determination that the lower
attachment studs on the aft galley complex may be installed incorrectly
due to a missing instruction in the maintenance procedure task. This
proposed AD would require a one-time inspection of the lower attachment
studs on the aft galley complex, and depending on findings,
accomplishment of applicable corrective actions, as specified in a
European Union Aviation Safety Agency (EASA) AD, which is proposed for
incorporation by reference (IBR). The FAA is proposing this AD to
address the unsafe condition on these products.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2024-0073, dated March 18, 2024
(EASA AD 2024-0073) (also referred to as the MCAI), to correct an
unsafe condition for certain Airbus SAS Model Airbus A350-941 and A350-
1041 airplanes. The MCAI states that the maintenance procedure task of
the galley lower attachment stud installation did not provide the
required maximum distance between the top of the threaded sleeve and
the top of the threaded stud, which could lead to a wrong installation
of the lower attachment stud having part number (P/N) XP14-070-007800,
P/N XP14-070-019100, P/N XP14-070-005400, P/N XP14-070-008400, and P/N
XP14-070-001100 on the aft galley complex. The MCAI also states that
the affected parts are the lower attachment stud having P/N XP14-070-
007800, P/N XP14-070-019100, P/N XP14-070-005400, P/N XP14-070-008400,
and P/N XP14-070-001100 for which the as previously described
incomplete maintenance procedure task has been accomplished after the
airplane date of manufacture and before January 2024; and the lower
attachment stud P/N XP14-070-019100 which has been installed after the
airplane date of manufacture, and before January 2024, in accordance
with the instructions of Airbus Alert Operators Transmission A25P023-
22, Revision 01, dated September 27, 2022.
The FAA is proposing this AD to address a possible wrong
installation for the lower attachment stud having part number (P/N)
XP14-070-007800, P/N XP14-070-019100, P/N XP14-070-005400, P/N XP14-
070-008400, and P/N XP14-070-001100 on the aft galley complex. This
condition, if not detected and corrected, could lead to galley module
detachment, with possible consequent injury to cabin crew and
passengers, and reduced evacuation capacity from the airplane in case
of an emergency.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2024-1888.
Material Incorporated by Reference Under 1 CFR Part 51
EASA AD 2024-0073 specifies a one-time installation inspection of
the lower attachment stud having P/N XP14-070-007800, P/N XP14-070-
019100, P/N XP14-070-005400, P/N XP14-070-008400, and P/N XP14-070-
001100 on the aft galley complex; and depending on findings (the
distance between the top of the threaded sleeves and the top of the
threaded studs exceeds specified limits), accomplishment of applicable
corrective actions (tightening the applicable threaded studs).
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 ADDRESSES.
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
referenced above. The FAA is issuing this NPRM after determining that
the unsafe condition described previously is likely to exist or develop
in other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2024-0073 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
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, the
FAA proposes to incorporate EASA AD 2024-0073 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2024-0073 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2024-0073 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 2024-
0073. Material required by EASA AD 2024-0073 for compliance will be
available at regulations.gov under Docket No. FAA-2024-1888 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 32 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 3 work-hours x $85 per hour = $0 Up to $255........... Up to $8,160.
$255.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition action that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need this on-condition action:
[[Page 58083]]
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
1 work-hour x $85 per hour = $85 per $10 $95
stud adjustment.....................
------------------------------------------------------------------------
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
