Rules and Regulations Federal Register 43909 Vol. 86, No. 152 Wednesday, August 11, 2021 DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2021–0652; Project Identifier MCAI–2020–00271–R; Amendment 39–21683; AD 2021–16–20] RIN 2120–AA64 Airworthiness Directives; PZL Swidnik S.A. Helicopters AGENCY : Federal Aviation Administration (FAA), DOT. ACTION : Final rule; request for comments. SUMMARY : The FAA is adopting a new airworthiness directive (AD) for certain PZL Swidnik S.A. Model PZL W–3A helicopters. This AD requires visually inspecting the bonding on a certain part- numbered fairing installed on a certain part-numbered vibration absorber, improving the bonding if necessary, using improved installation procedures to secure the fairing to the vibration absorber, and removing certain parts from service. This AD also prohibits installing the affected part unless it is inspected and installed per the AD requirements. This AD was prompted by a report of a broken bolt securing the fairing to the vibration absorber that resulted from an incorrect torque value for the nut used to secure the fairing to the vibration absorber. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD becomes effective August 26, 2021. The FAA must receive comments on this AD by October 12, 2021.

FOR FURTHER INFORMATION CONTACT : 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. SUPPLEMENTARY INFORMATION : Background EASA, 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 Wytwo ´ rnia Sprze ˛tu Komunikacyjnego (WSK) ‘‘PZL-S ´ widnik’’ Spo ´ 5 ka 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. Accordingly, EASA AD 2020–0038 requires the use of improved installation instructions to secure the affected fairing to the vibration absorber. FAA’s Determination These 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. Related Service Information The FAA reviewed WYTWO ´ RNIA SPRZE ˛ TU KOMUNIKACYJNEGO ‘‘PZL- S ´ widnik’’ Spo ´ 5 ka 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 nonconformity and 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. AD Requirements This 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 VerDate Sep<11>2014 17:21 Aug 10, 2021 Jkt 253001 PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 E:\FR\FM\11AUR1.SGM 11AUR1 jbell on DSKJLSW7X2PROD with RULES

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 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. Justification for Immediate Adoption and Determination of the Effective Date Section 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. 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. 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. 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. 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. 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) 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. 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 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. 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 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.
