SUPPLEMENTARY INFORMATION:

Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA
Emergency AD 20210072E, dated March 12, 2021 EASA Emergency AD
20210072E also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for Leonardo S.p.a.
formerly AgustaWestland S.p.A., Agusta S.p.A., and Costruzioni Aeronautiche Giovanni Agusta Model AB412 and AB412 EP helicopters, all serial numbers.
This AD was prompted by a report of a cracked hoist support assembly having part number P/N 2128800021 on a Leonardo S.p.a. Model AB412 military helicopter. The investigation is still ongoing. This same part is installed on Leonardo S.p.a. Model AB412 civil helicopters. The FAA is issuing this AD
to address cracking in a hoist support assembly which, if not addressed, could affect the structural integrity of the hoist support assembly, leading to in-flight detachment of the hoist assembly, and possibly resulting in damage to, and reduced control of, the helicopter. See the MCAI for additional background information.

country, and are approved for operation in the United States. Pursuant to the FAAs 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 these same type designs.
Requirements of This AD
This AD requires accomplishing the actions specified in EASA Emergency AD 20210072E, 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 FAAs 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 to use this process. As a result, EASA Emergency AD 20210072E is incorporated by reference in this FAA final rule. This AD, therefore, requires compliance with EASA Emergency AD 20210072E 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 Actions and Compliance Times in the EASA AD. Service information specified in EASA
Emergency AD 20210072E that is required for compliance with EASA
Emergency AD 20210072E is available on the internet at https
www.regulations.gov by searching for and locating Docket No. FAA2021
0724.
Interim Action The FAA considers this AD 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 553b3B 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 553d of the APA
authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause.
There are currently no domestic operators of these products. Therefore, the FAA finds that notice and opportunity for prior public comment are unnecessary pursuant to 5 U.S.C.
553b3B. In addition, for the foregoing reason, the FAA finds that good cause exists pursuant to 5 U.S.C.
553d 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
20210724; Project Identifier MCAI
202100321R 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
