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\n2021-18-12 PZL Swidnik S.A.: Amendment 39-21713; Docket No. FAA- 2021-0721; Project Identifier MCAI-2020-00616-R. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective October 12, 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. Model PZL W-3A helicopters, certificated in any category, with hoist type 76378 or hoist carrying assembly bracket (bracket) part number (P/N) 39.30.205.03.01 or 39.30.213.00.00 installed. \n\n(d) Subject \n\n\n\tJoint Aircraft Service Component (JASC) Code: 2500, Cabin Equipment/Furnishings. \n\n(e) Unsafe Condition \n\n\n\tThis AD was prompted by a report of fractured bracket bolts. The FAA is issuing this AD to prevent detachment of the bracket resulting in movement of the hoist carrying assembly around the axis of the remaining two lower brackets. The unsafe condition, if not addressed, could result in damage to the helicopter and loss of hoisted load or person(s). \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Required Actions \n\n\n\t(1) For helicopters with a hoist type 76378 installed, before further flight after the effective date of this AD: \n\t(i) Clean the area where bracket P/N 39.30.205.03.01 or 39.30.213.00.00 is installed to the fuselage structure using extraction or aliphatic naphtha. Using a flashlight and a magnifying glass with a minimum x5 magnification, inspect around the bracket edge and near each nut for cracked sealing compound. Refer to Figure 1 of WYTWORNIA SPRZETU KOMUNIKACYJNEGO ''PZL- Swidnik'' Spolka Akcyjna Mandatory Bulletin No. BO-37-19-296, dated July 30, 2019 (MB BO-37-19-296), for an example of cracked sealing compound. \n\t(A) If there is any cracked sealing compound, before further flight, remove the hoist from service. Reinstallation of a hoist type 76378 (that has not been removed from service) is allowed, provided that, before installation, the helicopter is modified in accordance with a method approved by the Manager, General Aviation and Rotorcraft Section, International Validation Branch, FAA; or EASA; or PZL Swidnik S.A.'s EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature. Following modification, all repetitive inspections, replacements, and applicable corrective actions must be done as specified in this AD. \n\t(B) If there are no cracks in the sealing compound, before further flight, replace each bracket bolt one-by-one by following Chapter II, paragraphsA.4.b. through i., of MB BO-37-19-296, except where it states to use extraction naphtha, you may substitute aliphatic naphtha. Remove each previously-installed bracket bolt, nut, washer, and cotter pin from service. \n\t(C) As an option to the actions required by paragraph (g)(1)(i)(B) of this AD, deactivate the hoist by following Chapter II, paragraph 3.2.2., of MB BO-37-19-296; and thereafter, before each flight, inspect the sealing compound by accomplishing the actions required by paragraph (g)(1)(i) of this AD. \n\t(ii) If there are no cracks in the sealing compound, within 25 hours time-in-service (TIS) after the replacement required by paragraph (g)(1)(i)(B) of this AD, and thereafter at intervals not to exceed 25 hours TIS, accomplish the actions required by paragraph (g)(1)(i) of this AD. \n\t(iii) Within 800 hoist cycles after the replacement required by paragraph (g)(1)(i)(B) of this AD, and thereafter at intervals not to exceed 800 hoist cycles, replace each bracket bolt by accomplishing the actions required by paragraph (g)(1)(i)(B) of this AD. For the purposes of this AD, a cycle is counted anytime the cable is extended and then retracted during flight or on the ground, for any cable length extended and retracted and with or without load. \n\t(2) For helicopters with a bracket P/N 39.30.205.03.01 or 39.30.213.00.00 installed, but no hoist installed, as of the effective date of this AD, do not install a hoist type 76378 unless the actions required by paragraph (g)(1) of this AD have been accomplished. \n\t(3) As of the effective date of this AD, do not install bracket P/N 39.30.205.03.01 or 39.30.213.00.00 and hoist type 76378 on any helicopter unless the actions required by paragraph (g)(1) of this AD have been accomplished. \n\n(h) Alternative Methods of Compliance (AMOCs) \n\n\n\t(1) The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the International Validation Branch, send it to the attention of the person identified in paragraph (i)(1) of this AD. Information may be emailed to: 9-AVS-AIR-730-AMOC@faa.gov. \n\t(2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager \n\n((Page 53195)) \n\nof the local flight standards district office/certificate holding district office. \n\n(i) Related Information \n\n\n\t(1) For more information about this AD, contact Fred Guerin, Aerospace Engineer, General Aviation & Rotorcraft Section, International Validation Branch, Compliance & Airworthiness Division, FAA, 2200 S 216th St., Des Moines, WA 98198; telephone (202) 267-7457; email fred.guerin@faa.gov. \n\t(2) The subject of this AD is addressed in European Union Aviation Safety Agency (EASA) Emergency AD 2019-0191-E, dated July 31, 2019.
