AD 2020-15-06

The FAA is adopting a new airworthiness directive (AD) for certain PZL Swidnik S.A. (PZL) Model W-3A helicopters. This AD requires repetitive inspections of the main transmission (Main XSMN) case for a crack, and depending on the inspection outcome, removing the WR-3 Main XSMN from service before further flight. This AD was prompted by a report of cracks in a Main XSMN case. 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 (AD): \n\n2020-15-06 PZL Swidnik S.A.: Amendment 39-21169; Docket No. FAA- 2018-0753; Product Identifier 2018-SW-033-AD. \n\n(a) Applicability \n\n\n\tThis AD applies to PZL Swidnik S.A. (PZL) Model W-3A helicopters, with a serial number up to 3X.10.12 inclusive, certificated in any category, with a main transmission (Main XMSN) case, part number (P/N) 64.21.0105 or P/N 64.22.0161, installed on a WR-3 Main XMSN P/N 64.21.3000 or P/N 64.21.4000. \n\n(b) Unsafe Condition \n\n\n\tThis AD defines the unsafe condition as a crack in the Main XMSN case. This condition could result in the structural failure and loss of load carrying capabilities of the Main XMSN and subsequent loss of control of the helicopter. \n\n(c) Effective Date \n\n\n\tThis AD becomes effective August 11, 2020. \n\n\n\t(d) Compliance \n\n\n\tYou are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time. \n\n(e) Required Actions \n\n\n\t(1) Within 5 hours time-in-service (TIS), using a light source and mirror, and paying particular attention to the area above the Main XSMN mounting flange as shown in Attachment 1, Sketch 2 LH side and Sketch 2 RH side of Wytw(oacute)rnia Sprz(eogon)tu Komunikacyjnego ''PZL-(Sacute)widnik'' Sp(oacute)(lstrok)ka Akcyjna Mandatory Bulletin No. BO-37-18-294, dated April 12, 2018 (BO-37-18- 294), visually inspect the Main XMSN case for a crack and indications of a crack.

Comments Invited \n\n\n\tThis AD is a final rule that involves requirements affecting flight safety, and the FAA did not provide you with notice and an opportunity to provide your comments prior to it becoming effective. However, the FAA invites you to participate in this rulemaking by submitting written comments, data, or views. The FAA also invites comments relating to the economic, environmental, energy, or federalism impacts that resulted from adopting this AD. The most helpful comments reference a specific portion of the AD, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit them only one time. The FAA will file in the docket all comments received, as well as a report summarizing each substantive public contact with FAA personnel concerning this rulemaking during the comment period. The FAA will consider all the comments received and may conduct additional rulemaking based on those comments. \n\nDiscussion \n\n\n\tEASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2018-0092-E, dated April 20, 2018, to correct an unsafe condition for Wytw(oacute)rnia Sprz(eogon)tu Komunikacyjnego ''PZL-(Sacute)widnik'' Sp(oacute)(lstrok)ka Akcyjna (WSK ''PZL-(Sacute)WIDNIK'' S.A.) Model PZL W-3A and PZL W-3AS helicopters with a serial number up to 3X.10.12 inclusive. EASA advises of an occurrence reported of finding cracks on the Main XMSN case housing. EASA further advises investigation results indicate the cracking mode has features of fatigue deterioration, but the root cause has not been determined. Accordingly, the EASA AD requires repetitive inspections of the Main XMSN case and, based on the inspection results, replacing certain parts. EASA also requires reporting the inspection results toPZL-(Sacute)widnik S.A. EASA considers its AD an interim action and further AD action may follow. EASA states this condition, if not detected and corrected, could lead to structural failure and loss of load carrying capabilities of the Main XSMN, possibly resulting in loss of helicopter control. \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 of 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 WYTW(Oacute)RNIA SPRZ(Eogon)TU KOMUNIKACYJNEGO ''PZL-(Sacute)widnik'' Sp(oacute)lka Akcyjna Mandatory Bulletin No. BO- 37-18-294, dated April 12, 2018, whichspecifies using a light source and mirror to inspect the Main XSMN case for indications of possible cracks, such as paint coat chipping, surface scratches, and oil leaks. This service information also specifies reporting certain information to PZL-(Sacute)widnik S.A., performing more in-depth inspections by performing a ground run test and checking for chalk mark discoloration, and if a crack exists, replacing the Main XSMN case before further flight. \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\nAD Requirements \n\n\n\tThe AD requires within 5 hours time-in-service (TIS), and thereafter at intervals not to exceed 25 hours TIS, for all PZL Model PZL W-3A helicopters serial number up to and including 3X.10.12 with Main XMSN case part number (P/N) 64.21.0105 or P/N 64.22.0161 installed on WR-3 Main XMSN P/N 64.21.3000 or P/N 64.21.4000, visually inspecting the Main XMSN case for a crack, a surface scratch, any paint coat chipping, and any oil leak and removing the Main XMSN from service before further flight if any of those conditions exist. \n\nDifferences Between This AD and the EASA AD \n\n\n\tThe EASA AD applies to Model PZL W-3AS helicopters, whereas this AD does not because that model is not FAA type-certificated. The EASA AD requires reporting certain information to PZL-(Sacute)widnik S.A., whereas this AD does not. \n\nInterim Action \n\n\n\tThe FAA considers this proposed AD to be an interim action. If final action is later identified, the FAA might consider further rulemaking then. \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 cause to adopt this rule without notice and comment, RFA analysis is notrequired. \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\nFAA's Justification and Determination of the Effective Date \n\n\n\tSection 553(b)(3)(B) of the Administrative Procedure Act (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. \n\tThere are no helicopters with this type certificate on the U.S. Registry. Therefore, the FAA finds good cause that 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\n((Page 45061)) \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 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\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 above, 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.
