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 2022–0256, dated December 19, 2022 (EASA AD 2022–0256) (also referred to as the MCAI), to correct an unsafe condition on all Safran Arriel 1C, Arriel 1C1, and Arriel 1C2 model turboshaft engines. The MCAI states that there were reports of false engine fire warnings. The subsequent investigation results identified a manufacturing noncompliance on the fire detectors, which caused a shift of the detection threshold towards temperature values that are lower than specified, potentially leading to a false engine fire warning. When two engines on a helicopter are fitted with an affected part, an engine fire warning could occur on both engines during the same flight. This condition, if not addressed, could lead to commanded inflight engine shut-down, possibly E:\FR\FM\20JAR1.SGM 20JAR1 3630 Federal Register / Vol. 88, No. 13 / Friday, January 20, 2023 / Rules and Regulations resulting in damage to the helicopter and reduced control of the helicopter. 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–2023–0021. Related Service Information Under 1 CFR Part 51 The FAA reviewed EASA AD 2022– 0256, which specifies procedures for replacing affected fire detectors. 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 ADDRESSES. 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 described 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 these same type designs. AD Requirements This AD requires accomplishing the actions specified in EASA AD 2022– 0256, except for any differences identified as exceptions in the regulatory text of this AD. This AD also prohibits the installation of affected fire detectors. 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 AD 2022–0256 is incorporated by reference in this AD. This AD requires compliance with EASA AD 2022–0256 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 AD 2022–0256 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 AD 2022–0256. Service information required by EASA AD 2022–0256 for compliance will be available at regulations.gov under Docket No. FAA–2023–0021 after this AD is published. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b)(3)(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. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies foregoing notice and comment prior to adoption of this rule because fire detectors that do not conform to the type design could lead to false engine fire warnings. Safran was informed of three occurrences of illumination of the engine fire alarm without confirmed fire (untimely illumination) on airframes equipped with affected fire detectors. False engine fire warnings are an unsafe condition requiring urgent corrective action because, if a helicopter is equipped with two engines with an affected fire detector installed, an engine fire warning could occur on both engines during the same flight. This unsafe condition, if not addressed, could lead to commanded in-flight engine shutdown, possibly resulting in damage to the helicopter and reduced control of the helicopter. Replacement of the fire detectors must be accomplished within 30 flight hours or 60 days from the effective date of this AD, whichever occurs first. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b)(3)(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 (RFA) The requirements of the 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 The FAA estimates that this AD affects 30 engines installed on helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Replace fire detectors .................. 1 work-hour × $85 per hour = $85 ................................... lotter on DSK11XQN23PROD with RULES1 Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

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.

about this final rule. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2023-0021; Project Identifier MCAI-
2022-01618-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 Kevin 
Clark, Aviation Safety Engineer, ECO Branch, FAA, 1200 District Avenue, 
Burlington, MA 01803. 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 2022-0256, dated December 19, 2022 
(EASA AD 2022-0256) (also referred to as the MCAI), to correct an 
unsafe condition on all Safran Arriel 1C, Arriel 1C1, and Arriel 1C2 
model turboshaft engines. The MCAI states that there were reports of 
false engine fire warnings. The subsequent investigation results 
identified a manufacturing non-compliance on the fire detectors, which 
caused a shift of the detection threshold towards temperature values 
that are lower than specified, potentially leading to a false engine 
fire warning. When two engines on a helicopter are fitted with an 
affected part, an engine fire warning could occur on both engines 
during the same flight. This condition, if not addressed, could lead to 
commanded in-flight engine shut-down, possibly

[[Page 3630]]

resulting in damage to the helicopter and reduced control of the 
helicopter.
    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-2023-0021.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2022-0256, which specifies procedures for 
replacing affected fire detectors. 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 
ADDRESSES.

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 described 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 these same type designs.

AD Requirements

    This AD requires accomplishing the actions specified in EASA AD 
2022-0256, except for any differences identified as exceptions in the 
regulatory text of this AD. This AD also prohibits the installation of 
affected fire detectors.

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 AD 2022-0256 is incorporated by reference in this AD. This AD 
requires compliance with EASA AD 2022-0256 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 AD 2022-0256 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 AD 
2022-0256. Service information required by EASA AD 2022-0256 for 
compliance will be available at regulations.gov under Docket No. FAA-
2023-0021 after this AD is published.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(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.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies foregoing notice and comment prior to adoption of this rule 
because fire detectors that do not conform to the type design could 
lead to false engine fire warnings. Safran was informed of three 
occurrences of illumination of the engine fire alarm without confirmed 
fire (untimely illumination) on airframes equipped with affected fire 
detectors. False engine fire warnings are an unsafe condition requiring 
urgent corrective action because, if a helicopter is equipped with two 
engines with an affected fire detector installed, an engine fire 
warning could occur on both engines during the same flight. This unsafe 
condition, if not addressed, could lead to commanded in-flight engine 
shut-down, possibly resulting in damage to the helicopter and reduced 
control of the helicopter. Replacement of the fire detectors must be 
accomplished within 30 flight hours or 60 days from the effective date 
of this AD, whichever occurs first. Accordingly, notice and opportunity 
for prior public comment are impracticable and contrary to the public 
interest pursuant to 5 U.S.C. 553(b)(3)(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 (RFA)

    The requirements of the 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

    The FAA estimates that this AD affects 30 engines installed on 
helicopters 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.
