A.1. 

delayed effective date would create 

uncertainty about the finality and 

effectiveness of the Board’s action and 

undermine the effectiveness of that 

action. Accordingly, the Board has 

determined that good cause exists to 

dispense with the notice, public 

comment, and delayed effective date 

procedures of the APA with respect to 

this final amendment to Regulation D. 

IV. Regulatory Flexibility Analysis 

The Regulatory Flexibility Act 

(‘‘RFA’’) does not apply to a rulemaking 

where a general notice of proposed 

rulemaking is not required.10 As noted 

previously, the Board has determined 

that it is unnecessary and contrary to 

the public interest to publish a general 

notice of proposed rulemaking for this 

final rule. Accordingly, the RFA’s 

requirements relating to an initial and 

final regulatory flexibility analysis do 

not apply. 

V. Paperwork Reduction Act 

In accordance with the Paperwork 

Reduction Act (‘‘PRA’’) of 1995,11 the 

Board reviewed the final rule under the 

authority delegated to the Board by the 

Office of Management and Budget. The 

final rule contains no requirements 

subject to the PRA.

preamble, the Board amends 12 CFR 

part 204 as follows: 

PART 204—RESERVE 

REQUIREMENTS OF DEPOSITORY 

INSTITUTIONS (REGULATION D) 

■ 1. The authority citation for part 204 

continues to read as follows: 

Authority: 12 U.S.C. 248(a), 248(c), 461, 

601, 611, and 3105. 

■ 2. Section 204.10 is amended by 

revising paragraph (b)(1) to read as 

follows:

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2022–13– 

11, which applied to all Airbus SAS 

Model A350–941 and –1041 airplanes. 

AD 2022–13–11 required revising the 

existing airplane flight manual (AFM) 

for airplanes equipped with affected 

flight control units (FCUs) and replacing 

any affected FCU with a serviceable 

FCU. This AD was prompted by reports 

of inadvertent auto flight system (AFS) 

altitude changes on the FCU; an 

investigation revealed that, depending 

on the ring selection, failure of the ALT 

knob on the FCU could change the 

target altitude. This AD continues to 

require certain actions in AD 2022–13– 

11, including replacing any affected 

FCU with a serviceable FCU, expands 

the requirement to revise the existing 

AFM for all airplanes, and prohibits the 

installation of affected parts; 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 October 30, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 30, 2024.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2022–13–11, 

Amendment 39–22097 (87 FR 39741, 

July 5, 2022) (AD 2022–13–11). AD 

2022–13–11 applied to all Airbus SAS 

Model A350–941 and –1041 airplanes. 

AD 2022–13–11 was prompted by a 

report of inadvertent AFS altitude 

changes on the FCU; an investigation 

revealed that, depending on the ring 

selection, failure of the ALT knob on the 

FCU could change the target altitude. 

AD 2022–13–11 required revising the 

existing AFM to include a procedure on 

the use of the AFS control panel ALT 

knob. AD 2022–13–11 also required 

replacing any affected FCU with a 

serviceable FCU, which would 

terminate the AFM revision following 

that replacement. The FAA issued AD 

2022–13–11 to address erroneous target 

altitude during descent, climb, or goaround, which could result in an 

unexpected vertical trajectory deviation 

and loss of correct situational awareness 

that could potentially result in 

uncontrolled impact with the ground. 

The NPRM published in the Federal 

Register on April 23, 2024 (89 FR 

30281). The NPRM was prompted by 

AD 2023–0215, dated December 11, 

2023; corrected December 13, 2023; 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union (EASA AD 2023–0215) 

(also referred to as the MCAI). The 


ddrumheller on DSK120RN23PROD with RULES1
78224 Federal Register / Vol. 89, No. 186 / Wednesday, September 25, 2024 / Rules and Regulations 

MCAI states that since EASA AD 2021– 

0260, dated November 18, 2021 (EASA 

AD 2021–0260), was issued, several 

operators reported additional incidents 

of inadvertent AFS altitude changes on 

airplanes equipped with serviceable 

FCUs. Airbus is investigating the cause 

of these reported events and, as a 

precautionary measure, expanded the 

applicability of the AFM Temporary 

Revision (TR) 121, Issue 1, to all 

airplanes, including those equipped 

with serviceable FCUs. For the reasons 

described above, EASA AD 2023–0215 

partially retains the requirements of 

EASA AD 2021–0260, which is 

superseded, and requires amendment of 

the applicable AFM by incorporating 

AFM TR 121, Issue 1, for airplanes 

equipped with serviceable FCUs. EASA 

AD 2023–0215 is still considered to be 

an interim action, and further EASA AD 

action may follow. 

In the NPRM, the FAA proposed to 

continue to require certain actions in 

AD 2022–13–11, including replacing 

any affected FCU with a serviceable 

FCU, as specified in EASA AD 2023– 

0215. The NPRM also proposed to 

require expanding the applicability of 

the requirement to revise the existing 

AFM to all Model A350–941 and –1041 

airplanes, including those equipped 

with serviceable FCUs, as specified in 

EASA AD 2023–0215. The NPRM also 

proposed to prohibit the installation of 

affected parts. The FAA is issuing this 

AD to address erroneous target altitude 

during descent, climb, or go-around, 

which could result in an unexpected 

vertical trajectory deviation and loss of 

correct situational awareness that could 

potentially result in uncontrolled 

impact with the ground. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–1007. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

Air Line Pilots Association, 

International (ALPA), who supported 

the NPRM without change. 

The FAA received an additional 

comment from Delta Air Lines (Delta). 

The following presents the comment 

received on the NPRM and the FAA’s 

response to the comment. 

Request To Extend Compliance Time 

for Replacement of Affected FCUs 

Delta requested that a new exception 

be added to paragraph (h) of the 

proposed AD to extend the compliance 

time for the replacement of affected 

FCUs from 25 months to 32 months, due 

to lack of parts availability. Delta 

pointed out that it is currently the only 

U.S. operator affected by AD 2022–13– 

11 and that Thales, the FCU 

manufacturer, focused on providing 

serviceable FCUs to European operators 

first, since EASA AD 2021–0260 was 

required to be accomplished sooner 

than AD 2022–13–11. Delta asserted that 

this resulted in Delta losing 

approximately 17 months of the time 

needed to accomplish the required 

replacement and therefore, requested 

the additional 7-month extension. 

Additionally, Delta pointed out that the 

replacement is secondary to the 

requirement to amend the AFM, which 

affects both serviceable and affected 

FCUs. Because the compliance time for 

the AFM amendment is retained as 

proposed, Delta maintained that an 

adequate level of safety is provided 

during the requested extension of the 

compliance time for replacing the 

affected FCUs. 

The FAA does not agree to extend the 

compliance time for replacing the 

affected FCUs. Delta did not provide 

enough justification to support an 

extension of the compliance time. In 

developing an appropriate compliance 

time for this action, the FAA considered 

the recommendations of the 

manufacturer, the urgency associated 

with the subject unsafe condition, the 

availability of required parts, and the 

practical aspect of accomplishing the 

required replacement within a period of 

time that corresponds to the normal 

scheduled maintenance for most 

affected operators. According to EASA, 

as the State of Design, parts availability 

was taken into consideration during 

development of the compliance time, 

which was determined to be sufficient 

to allow for the replacement of the 

affected parts to address the entire 

global A350 fleet. In consideration of 

these items, the FAA has determined 

that the proposed compliance time will 

ensure an acceptable level of safety. 

However, under the provisions of 

paragraph (i)(1) of this AD, the FAA will 

consider requests for approval of an 

extension of the compliance time if 

sufficient data are submitted to 

substantiate that the new compliance 

time would provide an acceptable level 

of safety. Therefore, no change is 

necessary to this AD. 

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, considered 

the comments received, 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.

Federal Register / Vol. 89, No. 186 / Wednesday, September 25, 2024 / Rules and Regulations 78225 

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.
