AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2022–16– 

06, which applied to certain Airbus SAS 

Model A330–200, A330–200 Freighter, 

A330–300, and A330–900 series 

airplanes; and all Model A340–200 and 

A340–300 series airplanes. AD 2022– 

16–06 required modifying the trimmable 

horizontal stabilizer actuator (THSA) 

installation, implementing the electrical 

load sensing device (ELSD) wiring 

provisions, and installing and activating 

the ELSD. This AD was prompted by 

tests that demonstrated that when the 

upper secondary load path (SLP) of the 

THSA is engaged, the THSA might not 

stall, with consequently no indication of 

SLP engagement, and by the recent 

determination that the required actions 

of AD 2022–16–06 cannot be 

accomplished on certain airplanes. This 

AD continues to require the actions in 

AD 2022–16–06 with revised 

procedures, and also requires additional 

actions for certain airplanes, 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 March 11, 

2025. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 11, 2025.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2022–16–06, 

Amendment 39–22135 (87 FR 51588, 

August 23, 2022) (AD 2022–16–06). AD 

2022–16–06 applied to certain Airbus 

SAS Model A330–201, –202, –203, 

–223, –223F, –243, –243F, –301, –302, 

–303, –321, –322, –323, –341, –342, 

–343, and –941 airplanes; and all Model 

A340–211, –212, –213, –311, –312, and 

–313 airplanes. AD 2022–16–06 

required modifying the THSA 

installation, implementing the ELSD 

wiring provisions, and installing and 

activating the ELSD. The FAA issued 

AD 2022–16–06 to address damage on 

the upper THSA SLP attachment with 

consequent mechanical disconnection 

of the THSA, possibly resulting in loss 

of control of the airplane. 

The NPRM published in the Federal 

Register on May 13, 2024 (89 FR 41365). 

The NPRM was prompted by AD 2024– 

0016, dated January 11, 2024, issued by 

EASA, which is the Technical Agent for 

the Member States of the European 

Union (EASA AD 2024–0016) (also 

referred to as the MCAI). The MCAI 

states it has been determined that the 

actions specified in EASA AD 2022– 

0039 cannot be accomplished on certain 

affected airplanes. Airbus subsequently 

developed additional instructions and 

corrections for the procedures. In 

certain circumstances, there may be no 

indication to the flightcrew of the 

engagement of the upper SLP of the 

THSA. This condition, if not addressed, 

could lead to damage on the upper 

THSA SLP attachment with consequent 

mechanical disconnection of the THSA, 

resulting in loss of control of the 

airplane. 

In the NPRM, the FAA proposed to 

continue to require modifying the THSA 

installation, implementing the ELSD 

wiring provisions, and installing and 

activating the ELSD, as specified in FAA 

AD 2022–16–06 and EASA AD 2022– 

0039, with revised procedures and 

additional actions, as specified in EASA 

AD 2024–0016. The FAA is issuing this 

AD to address the unsafe condition on 

these products. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–1294.

8902 Federal Register / Vol. 90, No. 22 / Tuesday, February 4, 2025 / Rules and Regulations 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

the 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 that comment 

and the FAA’s response. 

Request for Clarification of Mandatory 

Service Information 

The proposed AD would adopt EASA 

AD 2024–0016, which requires certain 

actions in accordance with a specific 

revision of Airbus Service Bulletin 

A330–27–3237, depending on the 

airplane serial number, and allows use 

of later-approved revisions. Delta 

requested that the FAA clarify the effect 

of any potential changes, including 

rework, that are proposed to be included 

in the forthcoming Revision 03 of 

Service Bulletin A330–27–3237. 

According to Delta, Airbus has 

indicated that Revision 03 will require 

additional work for any airplane 

modified by Airbus Service Bulletin 

A330–27–3237, Revision 01, dated June 

20, 2023, or Revision 02, dated February 

9, 2024. Delta added that Airbus 

planned to issue Revision 03 by the end 

of June 2024. 

The FAA provides the following 

clarification. Revision 03 of Airbus 

Service Bulletin A330–27–3237 has not 

been released by Airbus. EASA has 

informed the FAA of ongoing 

discussions with Airbus regarding the 

scope of additional work, the timeline 

for release of Revision 03 of that service 

bulletin, and a potential revision to 

EASA AD 2024–0016. If EASA issues a 

new AD because it is determined that 

additional work is needed to address the 

unsafe condition, then the FAA may 

consider further rulemaking at that time. 

This AD requires accomplishing the 

actions specified in EASA AD 2024– 

0016. The specific revisions of the 

service bulletins referenced in EASA 

AD 2024–0016, as well as laterapproved revisions of those service 

bulletins, are acceptable methods of 

compliance for accomplishing the 

requirements of this AD. If an operator 

elects to use a later-approved revision of 

a service bulletin, then all the actions 

identified as ‘‘RC’’ (required for 

compliance) in that service bulletin 

must be accomplished, unless 

alternative actions are approved under 

the provisions of paragraph (i) of this 

AD. The FAA has not changed this AD 

as a result of this comment. 

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. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

EASA AD 2024–0016 specifies 

procedures for installing and activating 

the ELSD and wiring provisions, and 

doing additional work that includes 

additional instructions and corrections 

for certain airplanes. 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 120 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Retained actions from AD 

2022-16-06.

57 work-hours × $85 per 

hour = $4,845.

Up to $23,000 ................... Up to $27,845 ................... Up to $3,341,400. 

New actions ....................... 5 work-hours × $85 per 

hour = $425.

$43,966 ............................. $44,391 ............................. Up to $5,326,920. 

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.
