Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A319-151N, -153N and -171N airplanes; Model A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes; and Model A321-251N, -252N, -253N, -271N, -272N, -251NX, -252NX, -253NX, -271NX, and -272NX airplanes. This AD was prompted by a safety review of the airplane fuel system, which identified that the electrical harness routing of the engine low pressure shut off valve (LPSOV) is not adequately protected against uncontained engine rotor failure (UERF). This AD requires modification of the LPSOV electrical harness routing on either the left-hand engine or the right-hand engine, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

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 certain Airbus SAS
Model A319-151N, -153N and -171N airplanes; Model A320-251N, -252N, -
253N, -271N, -272N, and -273N airplanes; and Model A321-251N, -252N, -
253N, -271N, -272N, -251NX, -252NX, -253NX, -271NX, and -272NX
airplanes. The NPRM published in the Federal Register on January 30,
2023 (88 FR 5817). The NPRM was prompted by AD 2022-0185, dated
September 5, 2022, issued by EASA, which is the Technical Agent for the
Member States of the European Union (EASA AD 2022-0185) (also referred
to as the MCAI). The MCAI states during a safety review of the airplane
fuel system, it was identified that the electrical harness routing of
the engine LPSOV is not adequately protected against UERF.
In the NPRM, the FAA proposed to require modification of the LPSOV
electrical harness routing on either the left-hand engine or the right-
hand engine, as specified in EASA AD 2022-0185. The FAA is issuing this
AD to address inadequate protection of the LPSOV against UERF. The
unsafe condition, if not addressed, could result in loss of engine fuel
isolation capability in case of UERF, possibly resulting in an
uncontrolled fire.
[[Page 69014]]
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-0026.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
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, 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 2022-0185 specifies procedures for modification of the
LPSOV electrical harness routing on either the left-hand engine (for
airplanes with LEAP-1A series engines installed) or the right-hand
engine (for airplanes with PW1100 series engines installed).
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 323 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
----------------------------------------------------------------------------------------------------------------
Up to 13 work-hours x $85 per hour = Up to $2,800........... Up to $3,905........... Up to $1,261,315.
$1,105.
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this AD may be covered under warranty, thereby reducing the cost impact
on affected operators.
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.
