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 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. \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 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 comments received and may conduct additional rulemaking based on those comments. \n\nConfidential Business Information \n\n\n\tConfidential 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 NPRM 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 NPRM, 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 NPRM. Submissions containing CBI should be sent to Kristin Bradley,Aviation Safety Engineer, Safety Management Section, Rotorcraft Standards 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\nDiscussion \n\n\n\tEASA, which is the Technical Agent for the Member States of the European Union, has issued AD No. 2017-0057, dated April 6, 2017, to correct an unsafe condition for PZL Model PZL W-3A helicopters. EASA advises of previous AD action requiring maintenance tasks and limitations in Revision 11 of Chapter 4 Airworthiness Limitations of PZL W-3A Instructions for Continued Airworthiness of Maintenance Manual AE 30.04.20.1 MM (English) and AE 30.04.20.1 IOT (Polish). Since then, EASA advises of revised maintenance tasks and more restrictive limitations in Revision 13 of AE 30.04.20.1 MM (English) and Revision 12 of AE 30.04.20.1 IOT (Polish). EASA statesthat these maintenance tasks and limitations are required for continued airworthiness and failure to comply with them could result in an unsafe condition. \n\tAdditional review after the EASA AD was issued determined that previous revisions of AE 30.04.20.1 MM (English) included an error for horizontal stabilizer part number (P/N) 30.13.600.00.04. Introduced in Revision 9, dated January 2012, AE 30.04.20.1 \n\n((Page 44687)) \n\nMM (English) stated the life limit for horizontal stabilizer P/N 30.13.600.00.04 up to serial number 06.001. The life limit should have been for serial number 06.001 and subsequent instead. This error was corrected in Revision 13 of AE 30.04.20.1 MM (English). \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 that the unsafe condition exists and is likely to exist or develop on other helicopters of the same type design. \n\nRelated Service Information \n\n\n\tPZL has issued Chapter 4 Airworthiness Limitations of PZL W-3A Instructions for Continued Airworthiness of Maintenance Manual AE 30.04.20.1 MM, Revision 13, dated January 2017. This revision of the service information includes establishing a life limit for horizontal stabilizer P/N 30.13.600.00.04 serial number 06.001 and subsequent. \n\nAD Requirements \n\n\n\tThis AD establishes a life limit for horizontal stabilizer P/N 30.13.600.00.04 serial number 06.001 and subsequent by requiring, before further flight, removing from service any horizontal stabilizer that has reached 15 or more years since the date of manufacture. Thereafter, this AD also requires removing from service any horizontal stabilizer before reaching 15 years since the date of manufacture. \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 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\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 typecertificate on the U.S. Registry. Therefore, 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\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. \n\tSubtitle 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 the product 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\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.
