surface of the fairing where the washers make contact, burnishing the affected area using abrasive paper, and washing the surface with a cleaning solution.
This AD then requires installing a new bolt, new washer, and new nut to connect the fairing to the vibration absorber. Additionally, this AD requires using a specified torque, torqueing each nut, locking each nut with a cotter pin, and if the specified torque cannot be accomplished, removing the washer and nut from service, installing airworthy parts, and reapplying torque. Finally, this AD prohibits installing an affected fairing or vibration absorber unless they meet the inspection and installation requirements of this AD.
Differences Between This AD and the EASA AD
EASA AD 20200038 applies to all serial-numbered Model PZL W3A and PZL W3AS helicopters, whereas this AD only applies to Model PZL W3A
helicopters with fairing part number P/
N 30.23.015.00.03 installed on vibration absorber P/N 30.23.000.00.04
installed. This AD does not apply to Model PZL W3AS helicopters because that model is not FAA type-certificated.

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 this type certificate 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.

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 Kristi Bradley, Program Manager, COS Program Management Section, Operational Safety Branch, Compliance &
Airworthiness Division, FAA, 10101
Hillwood Pkwy., Fort Worth, TX 76177;
telephone 817 2225110; email kristin.bradley@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 There are no costs of compliance with this AD because there are no helicopters with this type certificate 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

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.
