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 On November 16, 2016, we issued Emergency AD 2016-24-51 to correct an unsafe condition on Sikorsky Model S-92A helicopters with a TR pitch change shaft (TRPCS) assembly part number (P/N) 92358-06303-041 or P/N 92358-06303-042. Emergency AD 2016-24-51 was sent previously to all known U.S. owners and operators of these helicopters. Emergency AD 2016-24-51 requires removing TRPCS assemblies [[Page 95426]] with less than 5 hours time-in-service (TIS) since new or overhaul from service. Emergency AD 2016-24-51 also requires, for TRPCS assemblies with between 5 and 80 hours TIS since new or overhaul, borescope inspecting the TRPCS bearings and inspecting the angular contact bearing to determine whether there is free rotation, purged grease with metal particles, nicks or dents, or a cut, tear, or distortion on the bearing seal. If the bearings do not pass these inspections, Emergency AD 2016-24-51 requires replacing the TRPCS assembly. Emergency AD 2016-24-51 was prompted by a report of an operator losing TR control while in a hover. A preliminary investigation determined that binding in the TRPCS assembly double row angular contact bearing (bearing) resulted in reduced TR control. The investigation also found signs of excessive heat, which is an indicator of a binding bearing. Because binding will result in bearing failure rapidly, we limited Emergency AD 2016-24-51 to TRPCS assemblies with less than 80 hours time-in-service (TIS). The actions in Emergency AD 2016-24-51 are intended to detect a binding bearing and prevent loss of TR control and possible loss of control of the helicopter. FAA's Determination We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Related Service Information We reviewed Sikorsky Alert Service Bulletin 92-64-009, Basic Issue, dated November 2, 2016 (ASB 92-64-009). ASB 92-64-009 describes procedures for inspecting the TRPCS and bearing assemblies for damaged bearings and seals, purged grease with any metallic particles from the bearings, radial play in the bearings, and correct installation of the white Teflon seals, snap rings, and cotter pin. AD Requirements For helicopters with a TRPCS assembly P/N 92358-06303-041 or P/N 92358-06303-042 with less than 80 hours TIS installed, this AD requires: Removing from service TRPCS assemblies with less than 5 hours TIS since new or overhaul; For TRPCS assemblies with 5 or more hours TIS since new or overhaul, borescope inspecting the TRPCS bearing for damaged, incorrectly installed, or missing seals and inspecting the angular contact bearing for free rotation, purged grease with metallic particles, and damaged seals. If the TRPCS assembly has less than 10 hours TIS, performing a ground operation until the TRPCS assembly accumulates 10 hours TIS before performing the inspection on the angular contact bearing; and Replacing the TRPCS assembly if there is a missing, damaged, or incorrectly installed seal, snap ring, or cotter pin or if the bearing does not rotate freely, or if there is any purged grease with metallic particles. This AD does not apply to helicopters with a TRPCS assembly manufactured or overhauled on or after November 3, 2016. Differences Between This AD and the Service Information ASB 92-64-009 requires operators to contact Sikorsky if there are any discrepancies, and this AD does not. ASB 92-64-009 allows 20 hours TIS to perform the visual bearing inspection if the borescope inspection has already been performed, while this AD allows 20 hours TIS for TRPCS assemblies with 15 or more hours TIS. Costs of Compliance We estimate that this AD will affect 80 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. At an average labor rate of $85 per hour, borescope and visually inspecting the TRPCS assembly will require 16 work-hours, for a cost per helicopter of $1,360 and a cost of $108,800 for the U.S. fleet. If required, replacing a TRPCS assembly will require 16 work-hours and required parts will cost $4,000, for a cost per helicopter of $5,360. According to Sikorsky's 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 Sikorsky. Accordingly, we have included all costs in our cost estimate. FAA's Justification and Determination of the Effective Date Providing an opportunity for public comments prior to adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore, we found and continue to find that the risk to the flying public justifies waiving notice and comment prior to the adoption of this rule because the previously described unsafe condition can result in loss of TR control and certain actions must be accomplished before further flight or within 20 hours TIS, a very short interval for these helicopters. Since it was found that immediate corrective action was required, notice and opportunity for prior public comments before issuing this AD were impracticable and contrary to public interest and good cause existed to make the AD effective immediately by Emergency AD 2016-24- 51, issued on November 16, 2016, to all known U.S. owners and operators of these helicopters. These conditions still exists 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. 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 [[Page 95427]] 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.
