Federal Register / Vol. 86, No. 42 / Friday, March 5, 2021 / Rules and Regulations
This AD also requires the removal from service and replacement of each affected Stage 3 turbine wheel for Safran Helicopter Engines Astazou XIV B and Astazou XIV H model turbofan engines.
Differences Between This AD and the MCAI or Service Information EASA AD 20200161E requires operators to use Safran Helicopter Engines service information to perform the removal and replacement of affected Stage 2 HPT disks while this AD does not.
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.
The FAA has found the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because no domestic operators use this product. It is unlikely that the FAA
will receive any adverse comments or useful information about this AD from any U.S. operator. 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. FAA20210132
and Project Identifier MCAI2020
00947E 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 Wego Wang, Aviation Safety Engineer, ECO Branch, FAA, 1200 District Avenue, Burlington, MA
01803. 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 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 0 engines installed on helicopters of U.S. registry.
The FAA estimates the following costs to comply with this AD:

ESTIMATED COSTS
Action
Labor cost
Replace Stage 2 HPT disk
Replace Stage 3 turbine wheel

50 work-hours $85 per hour = $4,250
50 work-hours $85 per hour = $4,250

The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators.
