Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Airbus SAS Model A350–1041
airplanes. This proposed AD was
prompted by a report of rejected takeoffs after transient engine N1 shaft
speed exceedance. This proposed AD
would require replacing certain hydromechanical units (HMUs) with
serviceable HMUs before reaching a
reduced life limit, as specified in a
European Union Aviation Safety Agency
(EASA) AD, which is proposed for
incorporation by reference. This
proposed AD would also limit the
installation of affected parts under
certain conditions. 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 October 13,
2022.
ADDRESSES: 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 2022–0040,
dated March 8, 2022 (EASA AD 2022–
0040) (also referred to as the MCAI), to
correct an unsafe condition for certain
Airbus SAS Model A350–1041
airplanes.
This proposed AD was prompted by
a report of rejected take-offs after
transient engine N1 shaft speed
exceedance. It was found that the
combining spill valve (CSV) of the
engine HMU was slow to close due to
piston wear. A worn CSV piston does
not move fully and freely over its
operating range, and, when it moves to
the fully closed position, an excess of
fuel is sent to the fuel nozzles, which
eventually results in an N1 transient
shaft overspeed. The FAA is proposing
E:\FR\FM\29AUP1.SGM
29AUP1
52706
Federal Register / Vol. 87, No. 166 / Monday, August 29, 2022 / Proposed Rules
this AD to address a stuck CSV piston,
as a result of the CSV piston being worn,
which could significantly reduce engine
thrust, and if combined with a loss of
the second engine, could possibly result
in reduced control of the airplane. See
the MCAI for additional background
information.
Related Service Information Under 1
CFR Part 51
EASA AD 2022–0040 specifies
procedures for replacing each HMU
having part number G5020HMU02 with
a serviceable HMU before reaching a
reduced life limit. EASA AD 2022–0040
also limits the installation of affected
parts under certain conditions. 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, 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 2022–0040 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 2022–0040 by
reference in the FAA final rule. This
proposed AD would, therefore, require
compliance with EASA AD 2022–0040
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 2022–0040 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 2022–0040.
Service information required by EASA
AD 2022–0040 for compliance will be
available at regulations.gov by searching
for and locating Docket No. FAA–2022–
1064 after the FAA final rule is
published.
Interim Action
The FAA considers this proposed AD
interim action. If final action is later
identified, the FAA might consider
further rulemaking then.
Costs of Compliance
The FAA estimates that this proposed
AD would affect 29 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
7 work-hours × $85 per hour = $595 ..........................................................................................

Authority for This Rulemaking
Regulatory Findings
List of Subjects in 14 CFR Part 39
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.
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
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2022-0040, dated March 8, 2022 (EASA
AD 2022-0040) (also referred to as the MCAI), to correct an unsafe
condition for certain Airbus SAS Model A350-1041 airplanes.
This proposed AD was prompted by a report of rejected take-offs
after transient engine N1 shaft speed exceedance. It was found that the
combining spill valve (CSV) of the engine HMU was slow to close due to
piston wear. A worn CSV piston does not move fully and freely over its
operating range, and, when it moves to the fully closed position, an
excess of fuel is sent to the fuel nozzles, which eventually results in
an N1 transient shaft overspeed. The FAA is proposing
[[Page 52706]]
this AD to address a stuck CSV piston, as a result of the CSV piston
being worn, which could significantly reduce engine thrust, and if
combined with a loss of the second engine, could possibly result in
reduced control of the airplane. See the MCAI for additional background
information.

affected parts under certain conditions. 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, 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 2022-0040 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 2022-0040 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2022-0040 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 2022-0040 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 2022-
0040. Service information required by EASA AD 2022-0040 for compliance
will be available at regulations.gov by searching for and locating
Docket No. FAA-2022-1064 after the FAA final rule is published.
Interim Action
The FAA considers this proposed AD interim action. If final action
is later identified, the FAA might consider further rulemaking then.
Costs of Compliance
The FAA estimates that this proposed AD would affect 29 airplanes
of U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
7 work-hours x $85 per hour = $595........................... \*\ $0 $595 $17,255
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost estimates for the parts specified in 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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:
Airbus SAS: Docket No. FAA-2022-1064; Project Identifier MCAI-2022-
00342-T.
[[Page 52707]]
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by October 13, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Airbus SAS Model A350-1041 airplanes,
certificated in any category, as identified in European Union
Aviation Safety Agency (EASA) AD 2022-0040, dated March 8, 2022
(EASA AD 2022-0040).
(d) Subject
Air Transport Association (ATA) of America Code 73, Engine Fuel
and Control.
(e) Unsafe Condition
This AD was prompted by a report of rejected take-offs after
transient engine N1 shaft speed exceedance. The FAA is issuing this
AD to address a stuck combined spill valve (CSV) piston of the
engine hydro-mechanical units (HMUs), which could significantly
reduce engine thrust, and if combined with a loss of the second
engine, could possibly result in reduced control of the airplane.
(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, EASA AD 2022-0040.
(h) Exceptions to EASA AD 2022-0040
(1) Where EASA AD 2022-0040 refers to its effective date, this
AD requires using the effective date of this AD.
(2) The ``Remarks'' section of EASA AD 2022-0040 does not apply
to this AD.
(3) Where paragraph (1) of EASA AD 2022-0040 specifies to
replace ``[b]efore an affected part exceeds the life limit as
defined in Table 1 of this [EASA] AD,'' this AD requires replacing
``before an affected part exceeds the life limit specified in Table
1 of EASA 2022-0040, or within 3 flight cycles after the effective
date of this AD, whichever occurs later.''
(4) Where Table 1 of EASA AD 2022-0040 specifies calendar
timeframes, for this AD replace the text ``31 March 2022 to 29, June
2023'' with ``the effective date of this AD through June 29, 2023.''
(i) Additional AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Large Aircraft Section, International Validation Branch, FAA, has
the authority to approve AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19,
send your request to your principal inspector or responsible Flight
Standards Office, as appropriate. If sending information directly to
the Large Aircraft Section, International Validation Branch, send it
to the attention of the person identified in paragraph (j)(2) of
this AD. Information may be emailed to: [email protected].
Before using any approved AMOC, notify your appropriate principal
inspector, or lacking a principal inspector, the manager of the
responsible Flight Standards 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, Large Aircraft
Section, International Validation 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): Except as required by
paragraph (i)(2) of this AD, if any service information referenced
in EASA AD 2022-0042 contains paragraphs that are labeled as RC, the
instructions in RC paragraphs, including subparagraphs under an RC
paragraph, must be done to comply with this AD; any paragraphs,
including subparagraphs under those paragraphs, that are not
identified as RC are recommended. The instructions in paragraphs,
including subparagraphs under those paragraphs, 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 instructions identified as RC can
be done and the airplane can be put back in an airworthy condition.
Any substitutions or changes to instructions identified as RC
require approval of an AMOC.
