Federal Register / Vol. 86, No. 222 / Monday, November 22, 2021 / Rules and Regulations
AD Requirements This AD requires within 25 hours time-in-service TIS or 30 days, whichever occurs first after the effective date of this AD, removing and dissembling a certain part-numbered M/
R pitch link assembly and visually inspecting a certain part-numbered M/R
clevis and rod end for wear, corrosion, and damage, which may be indicated by distortion, bending, a crack, or damaged M/R clevis threads, and removing any affected parts from service before further flight. This AD also requires visually inspecting a certain part-numbered universal bearing for binding, stiffness, wear, looseness, excess axial and radial play, and damage, which may be indicated by distortion, bending, or a crack. If certain discrepancies are found, and a certain part-numbered M/R pitch link assembly that has accumulated 5,000 or less total hours TIS is installed, this AD requires before further flight, removing a certain part-numbered universal bearing from service. If certain discrepancies are found, and a certain part-numbered M/R pitch link assembly that has accumulated more than 5,000
total hours TIS is installed, this AD
requires before further flight and depending on the discrepancies, removing a certain part-numbered universal bearing and the M/R clevis from service or removing only the universal bearing from service.
This AD also requires performing a purge grease of each universal bearing and performing a magnetic particle inspection of each M/R clevis for a crack in accordance with the applicable service information. Following the magnetic particle inspection, if there is a crack, this AD requires before further flight, removing each affected M/R
clevis from service. If there is no crack, this AD requires performing a selective brush cadmium plating and applying a chromate conversion coating.
This AD requires within 50 hours TIS
after completion of the initial inspections required by this AD, and thereafter at intervals not to exceed 50
hours TIS, using a 10X magnifying glass, visually inspecting the neck and threaded area of each M/R clevis for wear, corrosion, and damage, which may be indicated by distortion, bending, a crack, or damaged M/R clevis threads, and depending on the inspection results before further flight, removing the affected part from service and replacing with an airworthy part, and repeating the magnetic particle inspection of each M/R clevis.
Finally, AD requires within 150 hours TIS after the completion of the initial inspections required by this AD, and

thereafter at intervals not to exceed 150
hours TIS, repeating the visual inspection of each universal bearing for binding, stiffness, wear, looseness, excess axial and radial play, and damage, and performing a purge grease of each universal bearing.
Differences Between This AD and Transport Canada AD CF202126
Transport Canada AD CF202126
specifies compliance times in terms of air time, whereas this AD requires using hours TIS. Where the service information required by Transport Canada AD CF202126 specifies to report any signs of cracking to Bell Product Support Engineering, this AD
does not require reporting any information. Transport Canada AD CF
202126 specifies replacing any affected part, whereas this AD requires removing the affected part from service and then replacing with an airworthy part.
Interim Action The FAA considers this AD to be an interim action. Once final action has been identified, the FAA might consider further rulemaking.
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 if not corrected, the unsafe condition could lead to crack initiation at the M/R clevis neck or threaded area and consequent failure of the M/R pitch link, resulting in loss of control of the helicopter.
In addition, the compliance time for the required actions is within 25 hours TIS or 30 days, whichever occurs first after the effective date of this AD, a shorter time period than the time necessary for the public to comment and for publication of the final rule.

Therefore, notice and opportunity for prior public comment are impracticable and contrary to 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 forgo 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. FAA20211011;
Project Identifier MCAI202000867R
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 Hal Jensen, Aerospace Engineer, Operational Safety Branch, Compliance & Airworthiness Division, FAA, 950 LEnfant Plaza N SW, Washington, DC 20024; telephone 202
2679167; email hal.jensen@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.
