We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive. Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2016-0177, dated September 8, 2016, to correct an unsafe condition for Leonardo Helicopters (formerly Finmeccanica S.p.A. and AgustaWestland) Model AW189 helicopters with a tail assembly part number (P/N) 8G5350A00131. EASA advises that a crack was detected on the TGB fitting P/N 4F5350A04152 during a scheduled inspection of an AW189 helicopter. EASA advises that this condition, if not detected and corrected, could lead to crack propagation up to a critical length. This condition could reduce the assembly's ability to sustain loads from the TGB and tail rotor, possibly resulting to reduced helicopter control. The EASA AD consequently requires repetitive inspections of the fitting and replacing the fitting, depending on the inspections' outcome. EASA considers these actions to be interim and that further AD action may follow. The FAA is in the process of updating AgustaWestland's name changes to Finmeccanica S.p.A., and then to Leonardo Helicopters, on its FAA type certificate. Because this name change is not yet effective, this AD specifies AgustaWestland. FAA's Determination These helicopters have been approved by the aviation authority of Italy and are approved for operation in the United States. Pursuant to our bilateral agreement with Italy, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information Under 1 CFR Part 51 Leonardo Helicopters has issued Bollettino Tecnico No. 189-114, dated September 6, 2016 (BT), which specifies inspecting the TGB fitting within 30 flight hours or 1 month from the receipt of the BT, whichever comes first, and then at intervals not to exceed 150 flight hours. If a crack is found, the BT requires replacing the TGB fitting. This 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. Proposed AD Requirements This proposed AD would require within 30 hours time-in-service (TIS) and thereafter at intervals not to exceed 150 hours TIS, cleaning the areas around the Hi-lok holes and inspecting the TGB fitting for a crack. If a crack exists, this proposed AD would require replacing the part before the next flight. Differences Between This Proposed AD and the EASA AD The EASA AD requires you to provide a compliance record and return parts to Leonardo Helicopters if a crack is found on the fitting. This proposed AD would require no such actions. Interim Action We consider this proposed AD to be an interim action. The design approval holder is expected to develop a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking. Costs of Compliance We estimate that this AD affects 4 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect the following costs: Inspecting the TGB fitting would require 4 work-hours and no parts for a cost per helicopter of $340 and $1,360 for the U.S. fleet each inspection cycle. Replacing the TGB fitting would require 48 work-hours and parts would cost $30,000 for a cost of $34,080 per helicopter. According to Leonardo Helicopters' service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage by Leonardo Helicopters. Accordingly, we have included all costs in our cost estimate. 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. We are 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 We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the [[Page 7425]] distribution of power and responsibilities among the various levels of government. For the reasons discussed, I certify this proposed regulation: 1. Is not a ``significant regulatory action'' under Executive Order 12866; 2. Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and 4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): AgustaWestland S.p.A.: Docket No. FAA-2017-0619; Product Identifier 2016-SW-093-AD.
