Background On January 11, 2024, an Airbus Model A321neo airplane powered by CFM Model LEAP–1A engines experienced a loss of thrust control on engine 1 during a go-around. On February 4, 2024, the same Airbus Model A321neo airplane experienced N1 fluctuation/reduction on engine 2 during a go-around. A manufacturer investigation determined that significantly higher than expected fuel nozzle coking was creating back pressure in the fuel system that then triggered the fuel pump relief valve to open, reducing fuel flow to the engine and resulting in a reduction in thrust. This condition, if not addressed, could result in loss of engine thrust control and reduced control of the airplane. The FAA is issuing this AD to address the unsafe condition on these products. FAA’s Determination The FAA is issuing this AD because the agency determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. AD Requirements This AD requires replacement of the full set of fuel nozzles. Interim Action The FAA considers this AD to be an interim action. The 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 E:\FR\FM\20SER1.SGM 20SER1 77014 Federal Register / Vol. 89, No. 183 / Friday, September 20, 2024 / Rules and Regulations 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. prior notice and comment. Because FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. Regulatory Flexibility Act The FAA estimates that this AD affects 0 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: 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 Costs of Compliance ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Replace the full set of fuel nozzles ................ 40 work-hours × $85 per hour = $3,400 ........ $126,000 $129,400 $0 Authority for This Rulemaking The Amendment Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

SUPPLEMENTARY INFORMATION: Authority for This Rulemaking The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it modifies terminal airspace as required to preserve the safe and efficient flow of air traffic in the Fort Lauderdale, FL area. History The FAA published a NPRM for Docket No. FAA–2024–0053 in the Federal Register (89 FR 27691; April 18, 2024) proposing to amend the FLL, Class C airspace. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal. Ten comments were received. Discussion of Comments The FAA received nine comments supporting the amendment of the Fort Lauderdale-Hollywood International Airport Class C airspace. One comment was received that was outside of the scope of this rulemaking. Differences From the NPRM Subsequent to publication of the NPRM, the FAA identified inconsistent PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 77015 boundary area language used in the Area A, B, D, E, F, and G descriptions to describe boundaries aligned with either Oakland Park Boulevard or Hollywood Boulevard. This action makes minor editorial amendments to clearly indicate the affected area description boundaries alignment with the roads by inserting the words ‘‘aligned with’’ to each description referencing the roads. In the Area A description, ‘‘(the eastern most portion of Oakland Park Boulevard located in Lauderdale Beach)’’ is changed to read ‘‘(aligned with the easternmost portion of Oakland Park Boulevard located in Lauderdale Beach)’’; and ‘‘(the eastern most portion of Hollywood Boulevard located in Hollywood)’’ is changed to read ‘‘(aligned with the easternmost portion of Hollywood Boulevard located in Hollywood).’’ In the Area B description, ‘‘(the eastern most portion of Oakland Park Boulevard located in Lauderdale Beach)’’ is changed to read ‘‘(aligned with the easternmost portion of Oakland Park Boulevard located in Lauderdale Beach).’’ In the Area D description, ‘‘(the eastern most portion of Hollywood Boulevard located in Hollywood)’’ is changed to read ‘‘(aligned with the easternmost portion of Hollywood Boulevard located in Hollywood).’’ In the Area E description, ‘‘(the eastern most portion of Oakland Park Boulevard located in Lauderdale Beach)’’ is changed to read ‘‘(aligned with the easternmost portion of Oakland Park Boulevard located in Lauderdale Beach).’’ In the Area F description, ‘‘(the eastern most portion of Hollywood Boulevard located in Hollywood)’’ is changed to read ‘‘(aligned with the easternmost portion of Hollywood Boulevard located in Hollywood)’’; and ‘‘(the eastern most portion of Oakland Park Boulevard located in Lauderdale Beach)’’ is changed to read ‘‘(aligned with the easternmost portion of Oakland Park Boulevard located in Lauderdale Beach).’’ In the Area G description, ‘‘(the eastern most portion of Oakland Park Boulevard located in Lauderdale Beach)’’ is changed to read ‘‘(aligned with the easternmost portion of Oakland Park Boulevard located in Lauderdale Beach)’’; and ‘‘(the eastern most portion of Hollywood Boulevard located in Hollywood)’’ is changed to read ‘‘(aligned with the easternmost portion of Hollywood Boulevard located in Hollywood).’’ These minor editorial amendments are administrative and do not affect the airspace boundaries or operating requirements.

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 Mehdi 
Lamnyi, Aviation Safety Engineer, FAA, 2200 South 216th Street, Des 
Moines, WA 98198. Any commentary that the FAA receives which is not

this rulemaking.

Background

    On January 11, 2024, an Airbus Model A321neo airplane powered by 
CFM Model LEAP-1A engines experienced a loss of thrust control on 
engine 1 during a go-around. On February 4, 2024, the same Airbus Model 
A321neo airplane experienced N1 fluctuation/reduction on engine 2 
during a go-around. A manufacturer investigation determined that 
significantly higher than expected fuel nozzle coking was creating back 
pressure in the fuel system that then triggered the fuel pump relief 
valve to open, reducing fuel flow to the engine and resulting in a 
reduction in thrust. This condition, if not addressed, could result in 
loss of engine thrust control and reduced control of the airplane. The 
FAA is issuing this AD to address the unsafe condition on these 
products.

FAA's Determination

    The FAA is issuing this AD because the agency determined the unsafe 
condition described previously is likely to exist or develop in other 
products of the same type design.

AD Requirements

    This AD requires replacement of the full set of fuel nozzles.

Interim Action

    The FAA considers this AD to be an interim action. The 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

[[Page 77014]]

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 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

    The FAA estimates that this AD affects 0 engines installed on 
airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this AD:

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.
