SUPPLEMENTARY INFORMATION: Discussion On January 26, 2018, at 83 FR 3628, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to Bell Model 429 helicopters, serial number (S/N) 57150, 57168, 57176, 57210 through 57216, 57265, 57266, 57267, and 57287, with a forward spar part number (P/N) 429-031-213-103 or 429-031-213-104 or actuator fitting assembly P/N 429-031-222-101 or 429-031-222-102 installed. The NPRM proposed to require marking a serial number on life- limited forward spars and actuator fitting assemblies. The proposed requirements were intended to prevent the forward spar or actuator fitting assembly from remaining in service after reaching its life limit. This condition could result in failure of a forward spar or actuator fitting assembly and subsequent collapse of the landing gear. The NPRM was prompted by AD No. CF-2017-02, dated January 16, 2017, issued by Transport Canada, which is the aviation authority for Canada, to correct an unsafe condition for Bell Model 429 helicopters, S/N 57150, 57168, 57176, 57210, 57211 through 57216, 57265, 57266, 57267, and 57287. Transport Canada advises that forward spars P/N 429-031-213- 103 and 429-031-213-104 and actuator fitting assembly P/N 429-031-222- 101 and 429-031-222-102 have life limits of 30,000 and 19,000 Retirement Index Numbers, respectively. However, Transport Canada states these parts are not serialized, and therefore their accumulated usage is difficult to track, which creates a risk that these parts could remain in service beyond their life limits. This condition could result in failure of the part. Comments We gave the public the opportunity to participate in developing this AD, but we received no comments on the NPRM. FAA's Determination These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to our bilateral agreement with Canada, Transport Canada, its technical representative, has notified us of the unsafe condition described in the Transport Canada AD. We are issuing this AD because we evaluated all information provided by Transport Canada and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed. Differences Between This AD and the Transport Canada AD The Transport Canada AD requires compliance within 12 months from its effective date, unless already accomplished. This AD requires compliance within 800 hours time-in-service. Related Service Information Under 1 CFR Part 51 We reviewed Bell Helicopter Alert Service Bulletin 429-16-34, dated November 10, 2016, which specifies [[Page 32202]] procedures for permanently marking each forward spar and actuator fitting assembly with the serial number of the helicopter. 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. Other Related Service Information We also reviewed Bell Helicopter Model 429 Maintenance Manual BHT- 429-MM-1, Chapter 4, Airworthiness Limitations Schedule, Revision 26, dated September 9, 2016, which specifies airworthiness life limits and inspection intervals for parts installed on Model 429 helicopters. Costs of Compliance We estimate that this AD affects 6 helicopters of U.S. Registry and that labor costs average $85 per work-hour. We estimate that marking the forward spars and actuator fitting assemblies requires 1 work-hour, and no parts are needed. Based on these estimates, we expect a total cost of $85 per helicopter and $510 for the U.S. fleet. 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 helicopters identified in this rulemaking action. Regulatory Findings 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. For the reasons discussed above, I certify that this AD: (1) Is not a ``significant regulatory action'' under Executive Order 12866; (2) Is not a ``significant rule'' under 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 AD and placed it in the AD docket.
