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 rulemaking during the comment period. We will consider all the comments we receive and may conduct additional rulemaking based on those comments. Discussion Transport Canada, which is the aviation authority for Canada, issued Emergency AD No. CF-2018-18, dated July 11, 2018, to correct an unsafe condition for Bell Model 429 helicopters. Transport Canada advises of two reports of T/R gearbox assemblies loosely attached to the gearbox support. According to Transport Canada, this condition could lead to structural damage and possible loss of control of the helicopter. As a result, on July 20, 2018, we issued Emergency AD 2018-15-51 (Emergency AD 2018-15-51), which required inspecting the T/R gearbox installation for looseness, visually inspecting the T/R gearbox retaining hardware and support attachment point areas, and torque inspecting the gearbox retaining nuts. Depending on the inspection results, Emergency AD 2018-15-51 required replacing or repairing the affected parts in accordance with FAA-approved procedures. Emergency AD 2018-15-51 was sent previously to all known U.S. owners and operators of these helicopters. The actions in Emergency AD 2018-15-51 were intended to prevent detachment of the T/R gearbox, loss of T/R control, and loss of control of the helicopter. After we issued Emergency AD 2018-15-51, we discovered an error in the replacement nut P/N. The required replacement nut P/N is NAS9926- 6L; not NAS9926-5L as incorrectly stated in Emergency AD 2018-15-51. Therefore, on July 26, 2018, we issued Emergency AD 2018-16-51 to supersede Emergency AD 2018-15-51 to correct the nut P/N. Emergency AD 2018-16-51 otherwise retains all of the requirements of Emergency AD 2018-15-51. Emergency AD 2018-16-51 was also sent previously to all known U.S. owners and operators of these helicopters. 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 the same type design. Related Service Information We reviewed Bell Alert Service Bulletin 429-18-40, dated July 6, 2018, which specifies a one-time inspection of the T/R gearbox installation and a one-time visual and torque inspection of the six installation attachment points. This service information also specifies contacting Bell Product Support Engineering with the results of the T/R gearbox installation inspection, any findings of the visual inspection, and the results of the torque inspection. AD Requirements This AD requires inspecting the T/R gearbox installation for looseness, visually inspecting the T/R gearbox retaining hardware and each support attachment point area, and torque inspecting each gearbox retaining nut. Depending on the inspection results, this AD requires replacing or repairing the affected parts in accordance with FAA- approved procedures. Differences Between This AD and the Transport Canada AD The Transport Canada AD applies to helicopters with specific serial numbers, whereas this AD applies to all Model 429 helicopters. The Transport Canada AD includes a calendar based compliance time, whereas this AD does not. The Transport Canada AD requires reporting certain information to Bell Product Support Engineering and this AD does not. If there is looseness, this AD requires performing the visual inspection and torque inspection before further flight, while the Transport Canada AD requires contacting Bell. Lastly, if the torque of a T/R gearbox retaining nut is below 160 in-lbs (19 Nm), this AD requires removing the T/R gearbox and inspecting the mounting surfaces and retaining hardware, while the Transport Canada AD requires contacting Bell. Interim Action We consider this AD to be an interim action. If final action is later identified, we might consider further rulemaking then. Costs of Compliance We estimate that this AD affects 90 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85.00 per work-hour. [[Page 53173]] Inspecting the T/R gearbox installation takes about 0.25 work-hour for an estimated cost of $21 per helicopter and $1,890 for the U.S. fleet. Inspecting the T/R gearbox retaining hardware and the support attachment points takes about 0.5 work-hour for an estimated cost of $43 per helicopter and $3,870 for the U.S. fleet. Replacing the nuts takes about 1 work-hour and parts cost about $20 for an estimated cost of $105 per helicopter and $9,450 for the U.S. fleet. FAA's Justification and Determination of the Effective Date An unsafe condition exists that required the immediate adoption of Emergency AD 2018-16-51, issued on July 26, 2018, to all known U.S. owners and operators of these helicopters. The FAA found that the risk to the flying public justified waiving notice and comment prior to adoption of this rule because there are required actions that must be completed before further flight and within 5 hours time-in-service. These conditions still exist and the AD is hereby published in the Federal Register as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13) to make it effective to all persons. Therefore, we find good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reasons stated above, we find that good cause exists for making this amendment effective in less than 30 days. 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 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, 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.
