ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding Airworthiness Directive (AD) 2017-14-03 for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. AD 2017-14-03 required an inspection and reduced the retirement lives of certain landing gear components. This new AD retains the requirements of AD 2017-14-03, reduces the retirement lives of additional landing gear components, and requires repeating the inspection. This AD was prompted by a revised analysis of the fatigue life of the landing gear. The actions of this AD are intended to prevent an unsafe condition on these products. DATES: This AD is effective October 30, 2018. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of August 11, 2017 (82 FR 34838, July 27, 2017). ADDRESSES: For service information identified in this final rule, contact your local Sikorsky Field Representative or Sikorsky's Service Engineering Group at Sikorsky Aircraft Corporation, 124 Quarry Road, Trumbull, CT 06611; telephone 1-800-Winged-S or 203-416-4299; email [email protected].

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to remove AD 2017-14-03, Amendment 39-18947 (82 FR 34838, July 27, 2017) (AD 2017-14-03) and add a new AD. AD 2017-14-03 applied to Sikorsky Model S-92A helicopters and required inspecting and reducing the retirement lives of certain landing gear components. AD 2017-14-03 was prompted by Sikorsky's updated fatigue analysis of the nose and main landing gear, which revealed that certain components required a reduced service life and one component required a repetitive visual and ultrasonic inspection. When we issued AD 2017-14-03, we determined that the age of the existing U.S. fleet and the compliance time for the repetitive inspection would allow enough time for notice and public comments on some actions. The NPRM published in the Federal Register on May 17, 2018 (83 FR 22883). The NPRM proposed to retain the actions in AD 2017-14-03, reduce the life limits of additional components, and require repeating the visual and ultrasonic inspections. These actions are intended to detect and prevent cracks or failure of a landing gear component, which could result in damage and loss of control of the helicopter. Comments We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM. FAA's Determination We have reviewed the relevant information and determined that an unsafe condition exists and is likely to exist or develop on other helicopters of this same type design and that air safety and the public interest require adopting the AD requirements as proposed. Related Service Information Under 1 CFR Part 51 We reviewed Ultrasonic Inspection Technique No. UT 5077, Revision 0, dated July 25, 2014 (UT 5077). UT 5077 contains the inspection method, equipment and materials, calibration, and inspection procedure for performing an ultrasonic inspection of nose gear actuator fitting part number (P/N) 92209-01101-101. 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 Sikorsky S-92 Helicopter Alert Service Bulletin 92-32-004, Basic Issue, dated January 30, 2015 (ASB). The ASB describes procedures for conducting a visual inspection of the nose landing gear (NLG) airframe fitting assembly and an ultrasonic inspection by following the procedures in UT 5077. Costs of Compliance We estimate that this AD affects 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 work-hour:Replacing a wheel axle P/N 2392-2334-001 requires 2 work- hours and required parts cost $22,000, for a cost per helicopter of $22,170. [[Page 48362]] Replacing a main landing gear (MLG) or NLG threaded hinge pin P/N 2392-2311-003 requires 1 work-hour and required parts cost $3,800, for a cost per helicopter of $3,885. Replacing a NLG cylinder P/N 2392-4006-005 requires 1 work-hour and required parts cost $27,200, for a cost per helicopter of $27,285. Replacing a NLG hinge pin P/N 2392-4312-003 requires 1 work-hour and required parts cost $4,400, for a cost per helicopter of $4,485. Replacing a landing gear actuator rod end P/N 2392-0876- 901 requires 1 work-hour and required parts cost $900, for a cost per helicopter of $985. Replacing a MLG cylinder P/N 2392-2006-005 requires 2 work-hours and required parts cost $33,100, for a cost per helicopter of $33,270. Replacing a MLG pin outboard P/N 2392-2312-003 requires 1 work-hour and required parts cost $4,300, for a cost per helicopter of $4,385. Replacing a MLG bulkhead left-hand side P/N 92201-08111- 105, -107, and -109 requires 70 work-hours and required parts cost $12,550, for a cost per helicopter of $18,500. Replacing a MLG bulkhead right-hand side P/N 92201-08111- 106, -108, and -110 requires 70 work-hours and required parts cost $12,550, for a cost per helicopter of $18,500. Inspecting the NLG airframe fitting assembly P/N 92209- 01101-041 requires 8 work-hours, and required parts cost is minimal, for a cost of $680 per helicopter and $54,400 for the U.S. fleet, per inspection cycle. If required, replacing a NLG actuator fitting P/N 92209- 01101-101 requires 70 work-hours, and required parts cost $10,000, for a cost per helicopter of $15,950. 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 have 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 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 a regulatory distinction is required, 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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.
