[Federal Register Volume 82, Number 227 (Tuesday, November 28, 2017)] [Rules and Regulations] [Pages 56165-56167] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-25558] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0491; Product Identifier 2016-SW-020-AD; Amendment 39-19031; AD 2017-19-01] RIN 2120-AA64 Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-76A, S-76B, S-76C, and S-76D helicopters. This AD requires inspecting the main rotor (M/R) servo pushrod (pushrod) assembly and applying slippage marks. This AD was prompted by an accident of a Sikorsky Model S-76C helicopter caused by a failed pushrod assembly. The actions of this AD are intended to prevent an unsafe condition on these products. DATES: This AD is effective January 2, 2018. ADDRESSES: For service information identified in this final rule, contact Sikorsky Aircraft Corporation, Customer Service Engineering, 124 Quarry Road, Trumbull, CT 06611; telephone 1-800- [[Page 56166]] Winged-S or 203-416-4299; email: [email protected].

SUPPLEMENTARY INFORMATION: Discussion On June 5, 2017, at 82 FR 25748, 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 Model S-76A, S-76B, S-76C, and S-76D helicopters, serial numbers up to and including 761075, with an M/R pushrod assembly part number (P/N) 76400-00034-059, 76400-00014- 074, 76400-00014-076, or 76400-00014-077 installed. The NPRM proposed to require inspecting each pushrod assembly and applying two slippage marks across each control rod and jamnut. Depending on the outcome of the inspection, the NPRM proposed to require replacing the pushrod assembly or inspecting the jamnut. Depending on the outcome of inspecting the jamnut, the NPRM proposed to require replacing the pushrod assembly or applying 140 inch-pounds of torque to the jamnut. The proposed requirements were intended to detect a loose jamnut and prevent failure of the pushrod assembly, loss of M/R flight control, and subsequent loss of control of the helicopter. Since the NPRM was issued, the FAA's Aircraft Certification Service has changed its organizational structure. The new structure replaces product directorates with functional divisions. We have revised some of the office titles and nomenclature throughout this Final rule to reflect the new organizational changes. Additional information about the new structure can be found in the Notice published on July 25, 2017 (82 FR 34564). 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 products of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed. Related Service Information We reviewed Sikorksy S-76 Helicopter Alert Service Bulletin 76-67- 58, Basic Issue, dated November 19, 2015 (ASB), which specifies a one- time inspection of the M/R forward, aft, and lateral pushrod assemblies and jamnuts for proper installation, condition, and security. If a pushrod or jamnut does not meet criteria specified in the inspections, the ASB specifies replacing the assembly. The ASB also specifies applying torque to each jamnut and applying two slippage marks across each control rod and jamnut. Differences Between This AD and the Service Information The Sikorsky ASB specifies returning any removed M/R pushrod assembly to Sikorsky. This AD does not require returning any parts to Sikorsky. Costs of Compliance We estimate that this AD affects 198 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 per work-hour. Inspecting the M/R pushrod assemblies takes about 2.2 work-hours for an estimated cost of $187 per helicopter and $37,026 for the U.S. fleet. Replacing an M/R pushrod assembly takes about 2 work-hours for a labor cost of $170. Parts to replace M/R pushrod assembly P/N 76400-00034-059 cost about $2,411 for a total estimated replacement cost of $2,581. Parts to replace M/R pushrod assembly P/N 76400-00014-074 cost about $2,224 for a total estimated replacement cost of $2,394. Parts to replace M/R pushrod assembly P/N 76400-00014-076 cost about $2,488 for a total estimated replacement cost of $2,658. Parts to replace M/R pushrod assembly P/N 76400-00014-077 cost about $2,414 for a total estimated replacement cost of $2,584. It takes a minimal amount of time to apply the slippage marks for a negligible cost. 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 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. [[Page 56167]] 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. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2017-19-01 Sikorsky Aircraft Corporation: Amendment 39-19031; Docket No. FAA-2017-0491; Product Identifier 2016-SW-020-AD.
