AD 2021-08-16

The FAA is adopting a new airworthiness directive (AD) for PZL Swidnik S.A. (PZL) Model W-3A helicopters. This AD requires repetitive inspections of a certain part-numbered stainless steel cable (cable) installed on a certain part-numbered hoist assembly, and depending on those inspection results, removing certain parts from service and reporting the results. This AD also prohibits installing the affected part unless it is inspected per the AD requirements. This AD was prompted by wear of and damage to the cable near the swaged terminal due to movement of the hook assembly. The actions of this AD are intended to address an unsafe condition on these products.

Final rule; request for comments.

Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive: \n\n2021-08-16 PZL Swidnik S.A.: Amendment 39-21510; Docket No. FAA- 2021-0299; Project Identifier MCAI-2020-00253-R. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective May 11, 2021. \n\n(b) Affected ADs \n\n\n\tNone. \n\n(c) Applicability \n\n\n\tThis AD applies to PZL Swidnik S.A.

Background \n\n\n\tEASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0017, dated January 30, 2020, to correct an unsafe condition for all serial-numbered Wytwornia Sprzetu Komunikacyjnego (WSK) ''PZL-Swidnik'' Spolka Akcyjna (S.A.) Model PZL W-3A helicopters with a Collins Aerospace (formerly Goodrich) electric hoist assembly (hoist) part number (P/N) 76378-500 having stainless steel cable P/N 712952 installed. EASA advises that occurrences were reported of cables found worn out; the damage consisted of reduction of the cable diameter near the swaged terminal. EASA states that subsequent investigation identified that the extensive cable wear was possibly caused by flickering movement of the hook assembly in the stowage position during flights. EASA further states that this condition, if not detected and corrected, could lead to reduction of the cable strength, possibly resulting in an in-flight loss ofthe hoist load, injury to persons, or damage to and reduced control of the helicopter. \n\tAccordingly, EASA AD 2020-0017 requires repetitive inspections of the cable to detect cable condition and diameter restriction and based on those inspection results, either replacing parts or additional maintenance actions and reporting non-compliant inspection results to Collins Aerospace. For helicopters that do not have the affected hoist installed, EASA AD 2020-0017 allows installing an affected hoist provided that it is new (never previously installed), overhauled (never installed after overhaul), or has passed an inspection (no defect found, or defects corrected), less than 25 flight hours before installation, in accordance with the instructions of the service information. \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 FAAof the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all information provided by EASA and determining the unsafe condition exists and is likely to exist or develop on other helicopters of the same type design. \n\nRelated Service Information Under 1 CFR Part 51 \n\n\n\tThe FAA reviewed Goodrich Actuation Systems Alert Service Bulletin 76378-500-25-P01, Revision 0, dated December 3, 2019 (ASB 76378-500-25- P01). ASB 76378-500-25-P01 specifies procedures to visually inspect \n\n((Page 21918)) \n\nthe cable near the swaged terminal for cable diameter restriction, the hook assembly stowage force, and the hook assembly stowage at the up limit. ASB 76378-500-25-P01 also specifies corrective action and reporting certain data if the cable is not compliant due to cable diameter restriction and the results of the hook assembly stowage force inspection. \n\tASB 76378-500-25-P01 is an attachment to WYTWORNIA SPRZETU KOMUNIKACYJNEGO ''PZL-Swidnik'' Spolka Akcyjna Alert Service Bulletin No. ASB-37-19-309, dated January 28, 2020 (ASB-37-19-309). ASB 76378-500-25-P01 is incorporated by reference in this AD. ASB-37-19-309 is not incorporated by reference in this AD. \n\tThis 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 the ADDRESSES section. \n\nOther Related Service Information \n\n\n\tThe FAA also reviewed ASB-37-19-309. ASB-37-19-309 specifies accomplishing repetitive visual inspections of the cable near the swaged terminal for cable diameter restriction and a one-time inspection of the hook assembly stowage force. ASB-37-19-309 also provides a reminder to accomplish the hook assembly stowage procedure after each individual hoisting operation performed in flight or on the ground. \n\nAD Requirements \n\n\n\tThis AD requires within 25 hours time-in-service accumulated by the hoist (hoist hours) after the effective date of this AD, andthereafter at intervals not to exceed 25 hoist hours for all PZL Model W-3A helicopters with hoist P/N 76378-500 having stainless steel cable P/N 712952 installed, inspecting the cable for wear and damage, inspecting the measurement of the diameter of the cable, and removing the cable from service or replacing the cable with an airworthy part before further hoist operation if certain criteria is met. This AD also requires following certain reinstallation steps and reporting certain information. Finally, this AD prohibits installing an affected hoist or cable unless they meet the conditions as required by this AD. \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.) (5 U.S.C.) 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 seeking comment prior to the rulemaking. 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 reasons stated above, 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-2021-0299 and Project Identifier MCAI-2020-00253-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, Aerospace Engineer, General Aviation & Rotorcraft Section, International Validation Branch, 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 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 causeto adopt this rule without notice and comment, RFA analysis is not required. \n\nCosts of Compliance \n\n\n\tThere are no costs of compliance associated with this AD because there are no helicopters with this type certificate on the U.S. Registry. \n\nPaperwork Reduction Act \n\n\n\tA federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a currently valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. Public reporting for this collection of information is estimated to be approximately 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. All responses to this collection of information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to: Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524. \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 \n\n((Page 21919)) \n\ndetail 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 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. \n\nRegulatory Findings \n\n\n\tThe FAA determined that 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. \n\tFor the reasons discussed, I certify that this AD: \n\t1. Is not a ''significant regulatory action'' under Executive Order 12866, and \n\t2. 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.
