–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. 

DATES: This AD is effective November 9, 

2023. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 9, 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 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.

You may examine the MCAI in the 

AD docket at regulations.gov 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 × $85 per hour = $1,105 Up to $2,800 Up to $3,905 Up to $1,261,315. 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2022–18– 

12, which applied to all Airbus SAS 

Model A330–841 and –941 airplanes. 

AD 2022–18–12 required installing 

serviceable engine electronic control 

(EEC) software or EEC units having the 

serviceable software, limiting certain 

parts installation configurations, and 

prior or concurrent modification of EEC 

software. This AD was prompted by a 

determination that engine crystal icing 

protection could be (temporarily) lost if 

an erroneous total pressure value is 

provided by the airplane system, which 

is addressed through EEC software. This 

AD continues to require certain actions 

in AD 2022–18–12 and requires adding 

new limitations for intermixing of 

certain EEC software standards and a 

new operational limitation for engines 

with certain EEC software installed, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

incorporated by reference. This AD also 

prohibits the installation of certain 

engines under certain conditions. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective November 9, 

2023. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 9, 2023.
