Airworthiness Directives; Rolls-Royce 

Deutschland Ltd & Co KG Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Rolls-Royce Deutschland Ltd & Co KG 

(RRD) Model Trent XWB–97 engines. 

This AD was prompted by the 

manufacturer revising the existing 

engine time limits manual (TLM) to 

introduce new or more restrictive 

instructions and associated thresholds 

and intervals for life-limited parts. This 

AD requires revising the airworthiness 

limitations section (ALS) of the 

operator’s existing approved engine 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive instructions and associated 

thresholds and intervals for life-limited 

parts, as specified in a European Union 

Aviation Safety Agency (EASA) AD, 

which is incorporated by reference 

(IBR). The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective November 8, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 8, 2024. 

The FAA must receive comments on 

this AD by December 9, 2024.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

The FAA invites you to send any 

written data, views, or arguments about 

this final rule. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2024–2331; Project Identifier MCAI– 

2024–00169–E’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the final 

rule, explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this final rule 

because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to 

regulations.gov, including any personal 

information you provide. The agency 

will also post a report summarizing each 

substantive verbal contact received 

about this final rule. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this AD contain 

commercial or financial information 

that is customarily treated as private, 

that you actually treat as private, and 

that is relevant or responsive to this AD, 

it is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and they 

will not be placed in the public docket 

of this AD. Submissions containing CBI 

should be sent to Barbara Caufield, 

Aviation Safety Engineer, FAA, 2200 

South 216th Street, Des Moines, WA 

98198. Any commentary that the FAA 

receives which is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2024–0065, 

dated March 8, 2024 (EASA AD 2024– 

0065) (also referred to as the MCAI), to 

correct an unsafe condition on all RRD 

Model Trent XWB–97 engines. The 

MCAI states that the manufacturer 

published a revised TLM introducing 

new or more restrictive tasks and 

limitations. These new or more 

restrictive tasks and limitations include 

a change to the engine mount pin 

inspection interval and introducing a 

new thrust strut inspection. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–2331. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

The FAA reviewed EASA AD 2024– 

0065, which specifies instructions for 

accomplishing the actions specified in 

the applicable TLM, including 

performing maintenance tasks, replacing 

life-limited parts, and revising the 

existing approved maintenance or 

inspection program, as applicable, by 

incorporating the limitations, tasks, and 

associated thresholds and intervals 

described in the TLM. 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 

These products have been approved 

by the aviation authority of another 

country and are 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 is issuing this AD after 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. 

AD Requirements 

This AD requires accomplishing the 

actions specified in the MCAI described 

previously, except for any differences 

identified as exceptions in the 

regulatory text of this AD and except as 

discussed under ‘‘Differences Between 

this AD and the MCAI.’’ 

Differences Between This AD and the 

MCAI 

Where EASA AD 2024–0065 specifies 

revising the approved AMP within 12 

months after the effective date of EASA 

AD 2024–0065, this AD requires 

revising the ALS of the existing 

approved aircraft maintenance or 

inspection program, as applicable, 

within 30 days after the effective date of 

this 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 since coordinated 

with other manufacturers and CAAs to 

use this process. As a result, EASA AD 

2024–0065 is incorporated by reference 

in this AD. This AD requires 

compliance with EASA AD 2024–0065 

in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this AD. Using 

common terms that are the same as the 

heading of a particular section in EASA 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 89, No. 206 / Thursday, October 24, 2024 / Rules and Regulations 84805 

AD 2024–0065 does not mean that 

operators need comply only with that 

section. For example, where the AD 

requirement refers to ‘‘all required 

actions within compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in EASA AD 2024–0065. 

Material required by EASA AD 2024– 

0065 for compliance will be available at 

regulations.gov under Docket No. FAA– 

2024–2331 after this AD is published. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b) of the Administrative 

Procedure Act (APA) (5 U.S.C. 551 et 

seq.) authorizes agencies to dispense 

with notice and comment procedures 

for rules when the agency, for ‘‘good 

cause,’’ finds that those procedures are 

‘‘impracticable, unnecessary, or contrary 

to the public interest.’’ Under this 

section, an agency, upon finding good 

cause, may issue a final rule without 

providing notice and seeking comment 

prior to issuance. Further, section 

553(d) of the APA authorizes agencies to 

make rules effective in less than thirty 

days, upon a finding of good cause. 

The FAA justifies waiving notice and 

comment prior to adoption of this rule 

because no domestic operators use this 

product. It is unlikely that the FAA will 

receive any adverse comments or useful 

information about this AD from any U.S. 

operator. Accordingly, notice and 

opportunity for prior public comment 

are unnecessary, pursuant to 5 U.S.C. 

553(b). In addition, for the foregoing 

reason(s), the FAA finds that good cause 

exists pursuant to 5 U.S.C. 553(d) for 

making this amendment effective in less 

than 30 days. 

Regulatory Flexibility Act 

The requirements of the Regulatory 

Flexibility Act (RFA) do not apply when 

an agency finds good cause pursuant to 

5 U.S.C. 553 to adopt a rule without 

prior notice and comment. Because the 

FAA has determined that it has good 

cause to adopt this rule without prior 

notice and comment, RFA analysis is 

not required. 

Costs of Compliance 

There are no costs of compliance with 

this AD because there are no engines 

with this type certificate on the U.S. 

Registry. 

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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

Airbus SAS Model A350–941 and –1041 

airplanes. This AD was prompted by 

reports that engine nacelle anti-icing 

(NAI) forward bulkheads have been 

found with elongated locating holes. 

This AD requires a one-time detailed 

inspection of the engine NAI forward 

bulkhead locating holes for elongation 

and loose fasteners and applicable 

corrective actions, and prohibits the 

installation of affected parts under 

certain conditions, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is incorporated by 

reference (IBR). The FAA is issuing this 

AD to address the unsafe condition on 

these products. 

DATES: This AD is effective November 

29, 2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publications listed in this 

AD as of November 29, 2024. 

ADDRESSES: 

AD Docket: You may examine the AD 

docket at regulations.gov under Docket 

No. FAA–2024–1881; or in person at 

Docket Operations between 9 a.m. and 

5 p.m., Monday through Friday, except 

Federal holidays. The AD docket 

contains this final rule, the mandatory 

continuing airworthiness information 

(MCAI), any comments received, and 

other information. The address for

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 all Airbus SAS Model A350– 

941 and –1041 airplanes. The NPRM 

published in the Federal Register on 

July 3, 2024 (89 FR 55120). The NPRM 

was prompted by AD 2024–0060R1, 

dated April 16, 2024, issued by EASA, 

which is the Technical Agent for the 

Member States of the European Union 

(EASA AD 2024–0060R1) (also referred 

to as the MCAI). The MCAI states that 

certain engine NAI forward bulkheads 

may have elongated locating holes. 

These holes are used in the 

manufacturing process and closed with 

fasteners before delivery. It has been 

determined that these fasteners, if loose, 

may vibrate and cause further 

elongation of the locating holes, which, 

eventually, can reduce the NAI 

performance. This condition, if not 

detected and corrected, could lead to 

the undetected loss of NAI protection on 

both engines, possibly resulting in loss 

of control of the airplane. 

In the NPRM, the FAA proposed to 

require a one-time detailed inspection of 

the engine NAI forward bulkhead 

locating holes for elongation and loose 

fasteners and applicable corrective 

actions, and prohibit the installation of 

affected parts under certain conditions, 

as specified in EASA AD 2024–0060R1. 

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–2024–1881. 

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
