Background \n\n\n\tEASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0038, dated February 27, 2020 (EASA AD 2020-0038), to correct an unsafe condition for all serial- numbered Wytwornia Sprzetu Komunikacyjnego (WSK) ''PZL- Swidnik'' Spolka Akcyjna (S.A.) Model PZL W-3A and PZL W-3AS helicopters. EASA AD 2020-0038 advises that a bolt part number (P/N) 3003A-6-16-3 was found broken on fairing P/N 30.23.015.00.03 installed on vibration absorber P/N 30.23.000.00.04. EASA states further investigations identified that the maintenance instructions detailing how to secure the affected parts did not include the torque value information to tighten the castellated nut P/N 3336A- 6. EASA further states that this condition, if not corrected, could lead to detachment of the affected part from the helicopter and its subsequent contact with helicopter stationary or rotary parts, possibly resulting in damage to, and consequent reduced control of, the helicopter. \n\tAccordingly, EASA AD 2020-0038 requires the use of improved installation instructions to secure the affected fairing to the vibration absorber. \n\nFAA's Determination \n\n\n\tThese helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of the same type design. \n\nRelated Service Information \n\n\n\tThe FAA reviewed WYTWORNIA SPRZETU KOMUNIKACYJNEGO ''PZL-Swidnik'' Spolka Akcyjna Alert Service Bulletin No. ASB-37-19-307, dated January 27, 2020. This service information specifies checking (inspecting) the bonding between the fairing and vibration absorber star for any nonconformityand improving the bonding if necessary. This service information also specifies the specific torque to be used to tighten the castellated nuts during installation of the fairing onto the vibration absorber. \n\nAD Requirements \n\n\n\tThis AD requires, within 300 hours time-in-service after the effective date of this AD, removing from service each bolt P/N 3003A-6- 16-3, washer P/N 3402A-1, and castellated nut P/N 3336A-6 that secure fairing P/N 30.23.015.00.03 to vibration absorber P/N 30.23.000.00.04, and inspecting the bonding between the fairing and vibration absorber to determine if there is any anodic coating. If there is anodic coating, this AD requires polishing the \n\n((Page 43910)) \n\nsurface 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, thisAD 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. \n\nDifferences Between This AD and the EASA AD \n\n\n\tEASA AD 2020-0038 applies to all serial-numbered Model PZL W-3A and PZL W-3AS helicopters, whereas this AD only applies to Model PZL W-3A 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 W-3AS helicopters because that model is not FAA type-certificated. \n\nJustification for Immediate Adoption and Determination of the Effective Date \n\n\n\tSection 553(b)(3)(B) 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 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. \n\tThere 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. 553(b)(3)(B). In addition, for the foregoing reasons, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days. \n\nComments Invited \n\n\n\tThe 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. FAA-2021-0652; Project Identifier MCAI- 2020-00271-R'' 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. \n\tExcept 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. \n\nConfidential Business Information \n\n\n\tCBI 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) 222-5110; 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. \n\nRegulatory Flexibility Act \n\n\n\tThe requirements ofthe 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. \n\nCosts of Compliance \n\n\n\tThere are no costs of compliance with this AD because there are no helicopters with this type certificate on the U.S. Registry. \n\nAuthority for This Rulemaking \n\n\n\tTitle 49 of the United States Code specifies the FAA's 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 Agency's authority. \n\tThe 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 inair 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. \n\nRegulatory Findings \n\n\n\tThis 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. \n\tFor the reasons discussed, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866, and \n\t(2) Will not affect intrastate aviation in Alaska. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
