Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued Emergency AD 2024– 24–51, dated November 20, 2024 (the emergency AD), to address an unsafe VerDate Sep<11>2014 15:50 Dec 04, 2024 Jkt 265001 condition on all Airbus Helicopters Model EC225LP helicopters. The FAA sent the emergency AD to all known U.S. owners and operators of these helicopters. The emergency AD requires repetitively inspecting MRH sleeves having P/N 332A31–3071–00 and, depending on the results, replacing the MRH sleeve and its two blade pins. The emergency AD also prohibits installing this part-numbered MRH sleeve on any helicopter unless its requirements are met. The emergency AD was prompted by Emergency AD 2024–0215–E, dated November 14, 2024, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA Emergency AD 2024–0215–E) (also referred to as the MCAI), to correct an unsafe condition on Airbus Helicopters EC 225 LP helicopters. This reported crack is the second crack in the same area of this part-numbered MRH sleeve. The FAA issued Emergency AD 2022–14–51, issued on July 1, 2022, which published as a Final rule; request for comments in the Federal Register on July 19, 2022 (87 FR 42951), following EASA Emergency AD 2022–0130–E, dated June 30, 2022 (EASA Emergency AD 2022–0130–E), to address the unsafe condition of the first crack. The MCAI states that investigation of the second cracked MRH sleeve determined that its crack initiation could not be attributed to the root cause of cracking in the same part-numbered MRH sleeve addressed by EASA Emergency AD 2022–0130–E. EASA considers the MCAI an interim action. The FAA is issuing this AD to detect cracking in an MRH sleeve. This condition, if not addressed, could result in structural failure of an MRH sleeve, loss of a main rotor blade, and subsequent loss of control of the helicopter. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–2545. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed EASA Emergency AD 2024–0215–E, which requires repetitively inspecting MRH sleeves having P/N 332A31–3071–00 and, depending on the results, replacing the MRH sleeve and its two blade pins. EASA Emergency AD 2024–0215–E also prohibits installing this part-numbered MRH sleeve on any helicopter unless its requirements are met. 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. PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 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 EASA Emergency AD 2024–0215–E, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text 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 been coordinating this process with manufacturers and CAAs. As a result, EASA Emergency AD 2024–0215–E is incorporated by reference in this AD. This AD requires compliance with EASA Emergency AD 2024–0215–E 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 Emergency AD 2024–0215–E does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in EASA Emergency AD 2024– 0215–E. Material required by EASA Emergency AD 2024–0215–E for compliance will be available at regulations.gov under Docket No. FAA– 2024–2545 after this AD is published. Interim Action The FAA considers that this AD is an interim action. If final action is later identified, the FAA might consider further rulemaking then. 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 E:\FR\FM\05DER1.SGM 05DER1 Federal Register / Vol. 89, No. 234 / Thursday, December 5, 2024 / Rules and Regulations 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. An unsafe condition exists that required the immediate adoption of Emergency AD # 2024–24–51, issued on November 20, 2024, to all known U.S. owners and operators of these helicopters. The FAA found that the risk to the flying public justified waiving notice and comment prior to adoption of this rule because an MRH sleeve is part of an assembly that is critical to flight of a helicopter. In addition, cracking of the MRH sleeve may lead to catastrophic destruction of the main rotor head and loss of the helicopter. Since a second crack has occurred in the same area of the affected MRH sleeve, and as the FAA has no information pertaining to the extent of cracking of MRH sleeves that may currently exist in helicopters, the initial actions required by this AD must be accomplished before the first flight of the day. These conditions still exist, therefore, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b). In addition, 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, for the same reasons the FAA found good cause to forego notice and comment. khammond on DSK9W7S144PROD with RULES 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 29 helicopters of U.S. registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD. Inspecting the MRH sleeves (up to 5 affected MRH sleeves per helicopter) will take 1 work-hour for an estimated cost of up to $85 per helicopter and $2,465 for the U.S. fleet, per inspection VerDate Sep<11>2014 15:50 Dec 04, 2024 Jkt 265001 cycle. If required, replacing an MRH sleeve and its two blade pins will take 6 work-hours and parts will cost $115,000 for an estimated cost of $115,510 per replacement. 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.

SUMMARY: PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 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 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 establishes Class D airspace at Auburn University Regional Airport, Auburn, AL. History The FAA published a notice of proposed rulemaking for Docket No. FAA 2024–2062 in the Federal Register (89 FR 78832; September 26, 2024), proposing to establish Class D airspace and amend Class E airspace extending upward from 700 feet above the surface for Auburn University Regional Airport, Auburn, AL. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. Three favorable comments supporting the establishment of controlled airspace at Auburn University Regional Airport were received. Incorporation by Reference Class D and Class E airspace are published in paragraphs 5000 and 6005 of FAA Order JO 7400.11, Airspace Designations and Reporting Points, which is incorporated by reference in 14 CFR 71.1 on an annual basis. This document amends the current version of that order, FAA Order JO 7400.11J, dated July 31, 2024, and effective September 15, 2024. FAA Order JO 7400.11J is publicly available as listed in the ADDRESSES section of this document. These amendments will be published in the next update to FAA Order JO 7400.11. FAA Order JO 7400.11J lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points. The Rule This action amends 14 CFR part 71 by establishing Class D airspace for Auburn University Regional Airport, Auburn, AL, as a new air traffic control tower services the airport. Also, an airspace evaluation resulted in an amendment to decrease the size of the existing Class E E:\FR\FM\05DER1.SGM 05DER1

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus Helicopters Model EC225LP helicopters. The FAA previously sent 
this AD as an emergency AD to all known U.S. owners and operators of 
these helicopters. This AD was prompted by a report of a cracked main 
rotor hub (MRH) sleeve. This AD requires repetitively inspecting 
certain MRH sleeves and prohibits installing those MRH sleeves unless 
the inspection is done, 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 December 20, 2024. Emergency AD 2024-24-51, 
issued on November 20, 2024, which contains the requirements of this 
amendment, was effective with actual notice.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication identified in this AD as of December 
20, 2024.
    The FAA must receive comments on this AD by January 21, 2025.

not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    The FAA issued Emergency AD 2024-24-51, dated November 20, 2024 
(the emergency AD), to address an unsafe condition on all Airbus 
Helicopters Model EC225LP helicopters. The FAA sent the emergency AD to 
all known U.S. owners and operators of these helicopters. The emergency 
AD requires repetitively inspecting MRH sleeves having P/N 332A31-3071-
00 and, depending on the results, replacing the MRH sleeve and its two 
blade pins. The emergency AD also prohibits installing this part-
numbered MRH sleeve on any helicopter unless its requirements are met.
    The emergency AD was prompted by Emergency AD 2024-0215-E, dated 
November 14, 2024, issued by EASA, which is the Technical Agent for the 
Member States of the European Union (EASA Emergency AD 2024-0215-E) 
(also referred to as the MCAI), to correct an unsafe condition on 
Airbus Helicopters EC 225 LP helicopters. This reported crack is the 
second crack in the same area of this part-numbered MRH sleeve. The FAA 
issued Emergency AD 2022-14-51, issued on July 1, 2022, which published 
as a Final rule; request for comments in the Federal Register on July 
19, 2022 (87 FR 42951), following EASA Emergency AD 2022-0130-E, dated 
June 30, 2022 (EASA Emergency AD 2022-0130-E), to address the unsafe 
condition of the first crack. The MCAI states that investigation of the 
second cracked MRH sleeve determined that its crack initiation could 
not be attributed to the root cause of cracking in the same part-
numbered MRH sleeve addressed by EASA Emergency AD 2022-0130-E. EASA 
considers the MCAI an interim action.
    The FAA is issuing this AD to detect cracking in an MRH sleeve. 
This condition, if not addressed, could result in structural failure of 
an MRH sleeve, loss of a main rotor blade, and subsequent loss of 
control of the helicopter.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2545.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed EASA Emergency AD 2024-0215-E, which requires 
repetitively inspecting MRH sleeves having P/N 332A31-3071-00 and, 
depending on the results, replacing the MRH sleeve and its two blade 
pins. EASA Emergency AD 2024-0215-E also prohibits installing this 
part-numbered MRH sleeve on any helicopter unless its requirements are 
met.
    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 EASA 
Emergency AD 2024-0215-E, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text 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 been 
coordinating this process with manufacturers and CAAs. As a result, 
EASA Emergency AD 2024-0215-E is incorporated by reference in this AD. 
This AD requires compliance with EASA Emergency AD 2024-0215-E 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 Emergency AD 2024-0215-E does not mean that operators need 
comply only with that section. For example, where the AD requirement 
refers to ``all required actions and compliance times,'' compliance 
with this AD requirement is not limited to the section titled 
``Required Action(s) and Compliance Time(s)'' in EASA Emergency AD 
2024-0215-E. Material required by EASA Emergency AD 2024-0215-E for 
compliance will be available at regulations.gov under Docket No. FAA-
2024-2545 after this AD is published.

Interim Action

    The FAA considers that this AD is an interim action. If final 
action is later identified, the FAA might consider further rulemaking 
then.

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

[[Page 96519]]

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.
    An unsafe condition exists that required the immediate adoption of 
Emergency AD # 2024-24-51, issued on November 20, 2024, to all known 
U.S. owners and operators of these helicopters. The FAA found that the 
risk to the flying public justified waiving notice and comment prior to 
adoption of this rule because an MRH sleeve is part of an assembly that 
is critical to flight of a helicopter. In addition, cracking of the MRH 
sleeve may lead to catastrophic destruction of the main rotor head and 
loss of the helicopter. Since a second crack has occurred in the same 
area of the affected MRH sleeve, and as the FAA has no information 
pertaining to the extent of cracking of MRH sleeves that may currently 
exist in helicopters, the initial actions required by this AD must be 
accomplished before the first flight of the day. These conditions still 
exist, therefore, notice and opportunity for prior public comment are 
impracticable and contrary to the public interest pursuant to 5 U.S.C. 
553(b).
    In addition, 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, 
for the same reasons the FAA found good cause to forego notice and 
comment.

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 29 helicopters of U.S. 
registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this AD.
    Inspecting the MRH sleeves (up to 5 affected MRH sleeves per 
helicopter) will take 1 work-hour for an estimated cost of up to $85 
per helicopter and $2,465 for the U.S. fleet, per inspection cycle. If 
required, replacing an MRH sleeve and its two blade pins will take 6 
work-hours and parts will cost $115,000 for an estimated cost of 
$115,510 per replacement.

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.
