Federal Register / Vol. 86, No. 169 / Friday, September 3, 2021 / Rules and Regulations retirement life life limit of 10,000
landings for high landing gear aft crosstube P/Ns 412050010101, 412
050010107, 412050010111, and 412050045107. This service information also specifies procedures for inspecting a high landing gear aft crosstube that has already exceeded the new retirement life to defer the initial retirement life replacement.
AD Requirements For high landing gear aft crosstube P/
Ns 412050010101, 412050010
107, 412050010111, and 412050
045107, this AD requires determining the total number of landings. For purposes of this AD, a landing is counted anytime a helicopter lifts off into the air and then lands again regardless of the duration of the landing and regardless of whether the engine is shutdown. If the total number of landings cannot be determined, this AD
requires multiplying the total hours time-in-service accumulated by the high landing gear aft crosstube by 4. If the high landing gear aft crosstube has accumulated or exceeded 10,000 total landings, this AD requires removing the high landing gear aft crosstube from service. This AD also requires creating a component history card or equivalent record to establish a life limit of 10,000
total landings, and thereafter, removing any high landing gear aft crosstube from service before accumulating 10,000 total landings.

Differences Between This AD and the EASA AD
EASA AD 20170097 allows deferring the first replacement of a high landing gear aft crosstube that has accumulated 9,900 or more total landings as of the effective date of its AD by passing certain inspections, whereas this AD
does not allow that deferral. EASA AD
20170097 requires revising the AMP
and allows revision of the AMP as terminating action of its AD, whereas this AD does not contain those actions.
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 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. 553b3B. In addition, for the foregoing reasons, 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 data, views, or arguments about this final rule. Send your comments to an address listed under ADDRESSES.
Include Docket No. FAA20210718;
Project Identifier MCAI202000601R
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 Kenneth Cook, Airframe/Structural/Mechanical Engineer, Certification Section, Fort Worth ACO Branch, FAA, 10101
Hillwood Pkwy., Fort Worth, TX 76177;

which 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 FAAs 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 Agencys 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, 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.
