SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2022-0046, dated March 17, 2022 
(EASA AD 2022-0046), to correct an unsafe condition for all serial-
numbered Leonardo S.p.a. Model AB212, AB412, and AB412EP helicopters.
    This AD was prompted by reports of cracked tailboom attachment 
bolts and barrel nuts. The FAA is issuing this AD to address the 
fatigue cracking of tailboom attachment bolts. See EASA AD 2022-0046 
for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0046 requires a one-time replacement of the upper 
left-hand tailboom attachment bolt and an inspection of the other three 
tailboom attachment bolts and all four barrel nuts for corrosion and 
damage. If there is any corrosion or damage, EASA AD 2022-0046 requires 
replacing the attachment bolt or barrel nut as applicable. EASA AD 
2022-0046 also requires a torque check following each replacement of a 
tailboom attachment bolt or after tailboom installation and depending 
on the results of the torque check, corrective action.
    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.

Other Related Service Information

    The FAA also reviewed Leonardo Helicopters Service Bulletin Alert 
No. 412-170, dated March 1, 2022. This service information specifies 
procedures for inspecting and the replacing the tailboom attachment 
hardware.

FAA's Determination

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA, its technical representative, 
has notified the FAA of the unsafe condition described in its AD. The 
FAA is issuing this AD after evaluating all pertinent information and 
determining that the unsafe condition exists and is likely to exist or 
develop on other helicopters of the same type designs.

[[Page 41582]]

Requirements of This AD

    This AD requires accomplishing the actions specified in EASA AD 
2022-0046, described previously, as IBRed, except for any differences 
identified as exceptions in the regulatory text of this AD and as 
discussed under ``Differences Between this AD and EASA 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 AD 2022-0046 is IBRed in this FAA final rule. This AD, therefore, 
requires compliance with EASA AD 2022-0046 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 2022-0046 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 
2022-0046. Service information referenced in EASA AD 2022-0046 for 
compliance will be available at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2022-0806 after this final 
rule is published.

Differences Between This AD and EASA AD

    EASA AD 2022-0046 includes Model AB212 helicopters in the 
applicability; this AD does not because that helicopter model is not 
FAA type-certificated. Service information referenced in EASA AD 2022-
0046 specifies sending compliance forms to the manufacturer; this AD 
does not require that action. EASA AD 2022-0046 requires contacting the 
manufacturer for disposition instructions for damaged parts; this AD 
does not and instead requires that the parts be removed from service.

Interim Action

    The FAA considers this AD 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)(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.
    There are no helicopters with these type certificates on the U.S. 
Registry. Accordingly, notice and opportunity for prior public comment 
are unnecessary, pursuant to 5 U.S.C. 553(b)(3)(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.

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 
ADDRESSES. Include ``Docket No. FAA-2022-0806; Project Identifier MCAI-
2022-00377-R'' 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 
https://www.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 Jacob 
Fitch, Aerospace Engineer, COS Program Management Section, Operational 
Safety Branch, Compliance & Airworthiness Division, FAA, 10101 Hillwood 
Pkwy., Fort Worth, TX 76177; telephone (817) 222-4130; email [email protected]. Any commentary that the FAA receives that is not 
specifically designated as CBI will be placed in the public docket for 
this rulemaking.

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 
helicopters with these type certificates 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

[[Page 41583]]

Government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed, 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.
