Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
Background
The FAA is superseding
Airworthiness Directive (AD) 2020–21–
07, which applied to all Airbus SAS
Model A350–941 and –1041 airplanes.
AD 2020–21–07 required replacement of
affected passenger oxygen masks (which
includes re-identifying the parts). This
AD was prompted by a determination
that additional parts are subject to the
unsafe condition. This AD continues to
require the actions in AD 2020–21–07,
and also requires replacing additional
affected parts; as specified in a
European Union Aviation Safety Agency
(EASA) AD, which is incorporated by
reference. This AD also prohibits
installation of affected parts. The FAA
is issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective May 12,
2023.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of May 12, 2023.
ADDRESSES:
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2020–21–07,
Amendment 39–21280 (85 FR 64949,
October 14, 2020) (AD 2020–21–07). AD
2020–21–07 applied to all Airbus SAS
Model A350–941 and –1041 airplanes.
AD 2020–21–07 required replacement of
affected passenger oxygen masks (which
includes re-identifying the parts). The
FAA issued AD 2020–21–07 to address
sticking of the breathing bag on certain
passenger oxygen masks, which could
prevent the breathing bag from fully
inflating, and possibly injure cabin
occupants following a depressurization
event.
The NPRM published in the Federal
Register on December 22, 2022 (87 FR
78612). The NPRM was prompted by
AD 2022–0112, dated June 17, 2022,
issued by EASA, which is the Technical
Agent for the Member States of the
European Union (EASA AD 2022–0112)
(referred to after this as the MCAI). The
MCAI states that additional affected

parts (emergency passenger oxygen
container assembly having serial
number BEHJ–XXXX) have been
identified as being subject to the same
unsafe condition.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2022–1643.
In the NPRM, the FAA proposed to
continue to require the actions in AD
2020–21–07 and to require replacing
additional affected parts, as specified in
EASA AD 2022–0112. The NPRM also
proposed to prohibit the installation of
affected parts. The FAA is issuing this
AD to address sticking of the breathing
bag on certain passenger oxygen masks,
which could prevent the breathing bag
from fully inflating, and possibly injure
cabin occupants following a
depressurization event.
Discussion of Final Airworthiness
Directive
Comments
The FAA received no comments on
the NPRM or on the determination of
the cost to the public.
Additional Changes Made to This Final
Rule
Since the NPRM was published, the
FAA received a parts cost estimate for
the passenger oxygen masks. The FAA
has revised the Costs of Compliance
section of this final rule to include this
parts cost.
Conclusion
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
reviewed the relevant data and
determined that air safety requires
adopting this AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on this
product. Except for minor editorial
changes, and any other changes
described previously, this AD is
adopted as proposed in the NPRM.
None of the changes will increase the
economic burden on any operator.

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 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

The Amendment
(e) Unsafe Condition
This AD was prompted by a report that
sticking effects have been observed affecting
the breathing bag on certain passenger
oxygen masks, and by a determination that
additional parts are subject to the unsafe
condition. The FAA is issuing this AD to
address sticking of the breathing bag on
certain passenger oxygen masks. The unsafe
condition, if not addressed, could prevent the
breathing bag from fully inflating, and
possibly injure cabin occupants following a
depressurization event.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
(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.

ACTION: Final rule.
AGENCY:
The FAA is adopting a new
airworthiness directive (AD) for all The
Boeing Company Model 787–8, 787–9,
and 787–10 airplanes. This AD was
prompted by reports of ram air turbine
(RAT) pump barrel assembly failures,
which caused the RAT to fail to provide
hydraulic power. The failures were
determined to be caused by variations in
the bronze metal used during
manufacturing, which can result in
varying fatigue properties. This AD
requires an inspection or records review
to determine the part number of the
RAT pump and control module (PCM)
and of the RAT assembly, and
replacement of any RAT PCM or any
RAT assembly having certain part
numbers. This AD also prohibits the
installation of affected parts. The FAA
is issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective May 12,
2023.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of May 12, 2023.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all The Boeing Company Model
787–8, 787–9, and 787–10 airplanes.
The NPRM published in the Federal
Register on September 21, 2022 (87 FR
57653). The NPRM was prompted by
reports of RAT pump barrel assembly
failures, which caused the RAT to fail
to provide hydraulic power. The failures
were determined to be caused by
variations in the bronze metal used
during manufacturing, which can result
in varying fatigue properties. In the
NPRM, the FAA proposed to require an
inspection or records review to
determine the part number of the RAT
PCM and of the RAT assembly, and
replacement of any RAT PCM or any
RAT assembly having certain part
numbers. In the NPRM, the FAA also
proposed to prohibit the installation of
affected parts. The FAA is issuing this
AD to address fatigue or cracking of the
RAT hydraulic pump bronze cylinder
block. This condition, if not addressed,
could cause failure of the RAT pump
and subsequent loss of backup
hydraulic power for the flight controls,
which can result in loss of continued
safe flight and landing.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2020-21-07, Amendment 39-21280 (85 FR
64949, October 14, 2020) (AD 2020-21-07). AD 2020-21-07 applied to all
Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-21-07 required
replacement of affected passenger oxygen masks (which includes re-
identifying the parts). The FAA issued AD 2020-21-07 to address
sticking of the breathing bag on certain passenger oxygen masks, which
could prevent the breathing bag from fully inflating, and possibly
injure cabin occupants following a depressurization event.
The NPRM published in the Federal Register on December 22, 2022 (87
FR 78612). The NPRM was prompted by AD 2022-0112, dated June 17, 2022,
issued by EASA, which is the Technical Agent for the Member States of
the European Union (EASA AD 2022-0112) (referred to after this as the
MCAI). The MCAI states that additional affected parts (emergency
passenger oxygen container assembly having serial number BEHJ-XXXX)
have been identified as being subject to the same unsafe condition.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2022-1643.
In the NPRM, the FAA proposed to continue to require the actions in
AD 2020-21-07 and to require replacing additional affected parts, as
specified in EASA AD 2022-0112. The NPRM also proposed to prohibit the
installation of affected parts. The FAA is issuing this AD to address
sticking of the breathing bag on certain passenger oxygen masks, which
could prevent the breathing bag from fully inflating, and possibly
injure cabin occupants following a depressurization event.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
Additional Changes Made to This Final Rule
Since the NPRM was published, the FAA received a parts cost
estimate for the passenger oxygen masks. The FAA has revised the Costs
of Compliance section of this final rule to include this parts cost.
Conclusion
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 reviewed the relevant data and determined
that air safety requires adopting this AD as proposed. Accordingly, the
FAA is issuing this AD to address the unsafe condition on this product.
Except for minor editorial changes, and any other changes described
previously, this AD is adopted as proposed in the NPRM. None of the
changes will increase the economic burden on any operator.
Related Service Information Under 1 CFR Part 51
EASA AD 2022-0112 specifies procedures for replacing the affected
passenger oxygen masks (those passenger oxygen masks contained in each
affected emergency passenger oxygen container assembly), and re-
identifying each affected part. EASA AD
[[Page 20731]]
2022-0112 also prohibits the installation of affected parts.

Costs of Compliance
The FAA estimates that this AD affects 30 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.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2020-21- 6 work-hours x $85 Up to $4,250 (per $4,760 $61,880
07 (13 airplanes). per hour = $510. mask assembly).
New actions....................... 6 work-hours x $85 Up to $4,250 (per 4,760 142,800
per hour = $510. mask assembly).
----------------------------------------------------------------------------------------------------------------
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.
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.
