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

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 Emergency AD 

2024–0174–E, dated September 5, 2024 

(EASA AD 2024–0174–E) (also referred 

to as the MCAI), to correct an unsafe 

condition on certain RRD Model Trent 

XWB–97 engines. The MCAI states that 

damage to a fuel manifold flexible tube 

was reported, which led to a controlled, 

temporary engine fire and heat damage 

to the exterior and interior of the engine 

nacelle (thrust reverser C-ducts). The 

occurrence resulted in an in-flight shut 

down. The MCAI also states that the AD 

is considered an interim action and 

further AD action may follow. To 

address this potential unsafe condition, 

the manufacturer published service 

information that specifies procedures 

for a one-time set of visual and 

dimensional inspections of the fuel 

manifold main fuel hoses and corrective 

action instructions. This condition, if 

not addressed, in combination with 

additional failures, could lead to a more 

severe engine fire and result in damage 

to the airplane. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–2664. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

The FAA reviewed EASA AD 2024– 

0174–E, which specifies procedures for 

a one-time set of visual and dimensional 

inspections of the main fuel hose 

assembly of the fuel manifold to confirm 

softness, compliance, and lack of 

resistance, and for shrinkage, cracks, 

chafing, dents, kinks, necking, and 

degradation of the hose braid wire, and, 

if necessary, replacement of the main 

fuel hose assembly of the fuel manifold. 

EASA AD 2024–0174–E also specifies 

reporting the inspection results to RRD. 

EASA AD 2024–0174–E also allows 

installation of an affected part on any 

airplane provided that the part is 

serviceable and allows installation of an 

affected engine provided that the engine 

passed the required inspections, or the 

findings were corrected. 

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 material already 

described, except for any differences 

identified as exceptions in the 

regulatory text of this AD. 

Interim Action 

The FAA considers this AD to be an 

interim action. This unsafe condition is 

still under investigation by the 

manufacturer and, depending on the 

results of that investigation, the FAA 

may consider further rulemaking action. 

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. 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to a penalty for failure to comply with 

a collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a currently valid 

OMB Control Number. The OMB 

Control Number for this information 

collection is 2120–0056. Public 

reporting for this collection of 

information is estimated to take 

approximately 1 hour per response, 

including the time for reviewing 

instructions, searching existing data 

sources, gathering and maintaining the 

data needed, and completing and 

reviewing the collection of information.

Officer, Federal Aviation 

Administration, 10101 Hillwood 

Parkway, Fort Worth, TX 76177–1524. 

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.
