Federal Register / Vol. 86, No. 28 / Friday, February 12, 2021 / Rules and Regulations determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.
Related Service Information Under 1
CFR Part 51
The FAA reviewed IrvinGQ Limited Service Bulletin IGQSB033, Issue 2, dated December 2020 IrvinGQ SB
IGQSB033, Issue 2. This service information provides a listing of the affected parts and specifies procedures for inspecting the Harley-type buckle assemblies and repairing or replacing as necessary. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in ADDRESSES.
Other Related Service Information The FAA also reviewed Pilatus PC7
Service Bulletin No. 25015, Revision 1, dated December 22, 2020. This service information specifies inspecting and repairing the Harley-type buckle assemblies in accordance with IrvinGQ
SB IGQSB033, Issue 2.
AD Requirements This AD requires accomplishing the actions specified in the IrvinGQ Limited service information already described.
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 waiving notice and comment prior to adoption of this rule because detachment of a shoulder strap from the main harness assembly could lead to loss of pilot restraint during operational maneuvers. Because this model airplane is certificated in the acrobatic category, if the pilot is not restrained during aerobatic flight, or even some normal operations, it may

result in loss of airplane control, or injuries to the crew. For this reason, the FAA has determined that operators must comply with the actions required by this AD before further flight.
Accordingly, notice and opportunity for prior public comment are unnecessary, 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.

the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking.

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. FAA20210049
and Project Identifier MCAI2021
00033A 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.

Costs of Compliance The FAA estimates that this AD
affects 21 airplanes of U.S. registry. The FAA also estimates that it would take about .5 work-hour per product to comply with the inspection requirement of this AD. The average labor rate is $85
per work-hour.
Based on these figures, the FAA
estimates the cost of the AD on U.S.
operators would be $892.50 or $42.50
per product.
In addition, the FAA estimates that any necessary follow-on repair actions would take .5 work-hour, for a cost of $42.50 per seat harness. The FAA
estimates that any necessary replacements that may be required would take 3 work-hours and require parts costing $10,000, for a cost of $10,255 per seat harness. The FAA has no way of determining the number of airplanes that may need these actions.

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 Doug Rudolph, Aviation Safety Engineer, General Aviation & Rotorcraft Section, International Validation Branch, FAA, 901 Locust, Room 301, Kansas City, Missouri 64106. Any commentary that

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 FAA
has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required.

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
