Discussion Transport Canada, which is the aviation authority for Canada, has issued Canadian AD No. CF-2017-02, dated January 16, 2017, to correct an unsafe condition for BHTC Model 429 helicopters, serial numbers (S/ N) 57150, 57168, 57176, 57210, 57211 through 57216, 57265, 57266, 57267, and 57287. Transport Canada advises that forward spars part number (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. 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 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 We reviewed Bell Helicopter Alert Service Bulletin 429-16-34, dated November 10, 2016, which specifies 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 [[Page 3629]] specifies airworthiness life limits and inspection intervals for parts installed on Model 429 helicopters. Proposed AD Requirements This proposed AD would require cleaning and marking the helicopter's serial number on each forward spar P/N 429-031-213-103 and 429-031-213-104 and on each actuator fitting assembly P/N 429-031-222- 101 and 429-031-222-102. This proposed AD would also prohibit installing any affected part on any helicopter unless is has been marked in accordance with this proposed AD. Differences Between This Proposed AD and the Transport Canada AD The Transport Canada AD requires compliance within 12 months from its effective date, unless already accomplished. This proposed AD would require compliance within 800 hours time in service. Costs of Compliance We estimate that this proposed AD would affect 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 would require 1 work-hour and no parts would be 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 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 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.
