AD Requirements This AD requires, within 30 hours time-in-service TIS or 30 calendar days, whichever occurs first, inspecting each rotating and non-rotating scissor fitting with the bolts connecting the scissor fittings removed. For this initial inspection, this AD requires removing the cotter pins and bolts that connect the two scissor fittings, cleaning the outside surface of each scissor fitting, and using a flashlight to visually inspect each scissor fitting for a crack.
This AD also requires, at intervals not to exceed 50 hours TIS or 6 months, whichever occurs first, repetitive inspections of each scissor fitting without removing the bolts and separating the two scissor fittings. For these repetitive inspections, this AD
requires cleaning each scissor fitting, and while using a flashlight, visually inspecting each scissor fitting for a crack.
If during any inspection there is a crack, this AD requires replacing the MRH or swashplate guide, as applicable, before further flight.
This AD also prohibits installing an MRH or swashplate guide with an affected scissor fitting installed, even if new, unless the initial inspection has been accomplished.
Differences Between This AD and the EASA AD
The EASA AD requires detailed inspections, whereas this AD requires cleaning each scissor fitting and visually inspecting each scissor fitting using a flashlight. The EASA AD also requires reporting certain information, whereas this AD does not. The EASA AD allows

installing a new not previously installed MRH or swashplate guide, whereas this AD prohibits installing a new MRH or swashplate guide unless the initial inspection has been accomplished.
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.
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 the initial inspection must be completed within 30 hours TIS or 30
calendar days, whichever occurs first, and thereafter, the repetitive inspections must be completed within 50 hours TIS
or 6 months, 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. 553b3B.
In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553d for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forego notice and comment.
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. FAA20201177;
Project Identifier MCAI202001336R
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.

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 Fred Guerin, Aerospace Engineer, General Aviation and Rotorcraft Section, International Validation Branch AIR732, FAA, 2200 South 216th St., Des Moines, WA
98198; telephone 206 2313500; email fred.guerin@faa.gov. Any commentary that the FAA receives 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 The FAA estimates that this AD
affects 32 helicopters of U.S. Registry.
Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD.
Removing and installing the bolt and cotter pins in the initial inspection takes a minimal amount of time. Inspecting each scissor fitting takes about 0.5 workhour for an estimated cost of $43 per fitting, per inspection cycle. There are 2
scissor fittings installed on a helicopter, for an estimated cost of $85 per helicopter and $2,720 for the U.S. fleet, per inspection cycle. If required, replacing an MRH takes about 5 work-
