SUPPLEMENTARY INFORMATION:

Background

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2018-0082, dated April 11, 2018 
(EASA AD 2018-0082) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for Leonardo S.p.a. Model AW189 helicopters, if equipped with bubble 
windows kit part number 8G5620F00111.
    This AD was prompted by a report of a bubble window departing from 
the helicopter during flight. The FAA is issuing this AD to address 
degradation of the installation of the bubble windows, which could 
cause loss of a bubble window during flight, possibly resulting in 
damage to the helicopter and injury to persons on the ground. See the 
MCAI for additional background information.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2018-0082 specifies procedures for, among other actions, 
modifying the left-hand and right-hand bubble windows with an improved 
bubble window kit. 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

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
referenced above. 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 products of the same type 
design.

Requirements of This AD

    This AD requires accomplishing the actions specified in EASA AD 
2018-0082, described previously, as incorporated by reference, except 
for any differences identified as exceptions in the regulatory text of 
this AD and except as discussed under ``Differences Between this AD and 
the MCAI.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to

[[Page 31906]]

use this process. As a result, EASA AD 2018-0082 is incorporated by 
reference in this final rule. This AD, therefore, requires compliance 
with EASA AD 2018-0082 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 the EASA AD 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 the EASA AD. Service 
information specified in EASA AD 2018-0082 that is required for 
compliance with EASA AD 2018-0082 is available on the internet at 
https://www.regulations.gov by searching for and locating Docket No. 
FAA-2021-0446.

Differences Between This AD and the MCAI

    The requirements specified in paragraphs (1), (2), (3) and (5) of 
EASA AD 2018-0082 do not apply to this AD.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (5 U.S.C.) 
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 seeking comment prior to the rulemaking.
    There are currently no domestic operators of these products. 
Therefore, the FAA finds that notice and opportunity for prior public 
comment are unnecessary and 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 relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2021-0446; Project Identifier 2018-
SW-029-AD'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the AD, 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 
AD 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 AD.

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 Andrea 
Jimenez, Aerospace Engineer, Airframe and Propulsion Section, FAA, New 
York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; 
phone: 516-228-7330; fax: 516-794-5531; 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 (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 notice and comment, RFA analysis is not required.

Costs of Compliance

    Currently, there are no affected U.S.-registered helicopters. If an 
affected helicopter is imported and placed on the U.S. Register in the 
future, the FAA provides the following cost estimates to comply with 
this AD:

                  Estimated Costs for Required Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
32 work-hours x $85 per hour = $2,720.          $2,000           $4,720
------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the cost estimate.

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

    The FAA determined that this AD would not have federalism 
implications under Executive Order 13132. This AD would 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 this regulation:

[[Page 31907]]

    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.
