[Federal Register Volume 80, Number 186 (Friday, September 25, 2015)] [Proposed Rules] [Pages 57751-57753] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2015-24148] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-3942; Directorate Identifier 2014-SW-064-AD] RIN 2120-AA64 Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Helicopters AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede airworthiness directive (AD) 2014-07- 04R1 for certain Sikorsky Model S-92A helicopters. AD 2014-07-04R1 currently requires repetitive inspections in the upper deck area for incorrectly installed clamps and chafing between the electrical wires and the hydraulic lines and replacing any unairworthy wires or hydraulic lines. Since we issued AD 2014-07-04R1, the manufacturer has developed an alteration that corrects the unsafe condition described in AD 2014-07-04R1. This proposed AD would require altering the wiring system in the upper deck area. These proposed actions are intended to prevent a fire in an area of the helicopter without extinguishing capability and subsequent loss of control of the helicopter. DATES: We must receive comments on this proposed AD by November 24, 2015. ADDRESSES: You may send comments by any of the following methods:Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your comments electronically. Fax: 202-493-2251. Mail: Send comments to the U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590-0001.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to participate in this rulemaking by submitting written comments, data, or views. We also invite comments relating to the economic, environmental, energy, or federalism impacts that might result from adopting the proposals in this document. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit only one time. 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 proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this [[Page 57752]] proposal in light of the comments we receive. Discussion On March 28, 2014, we issued AD 2014-07-04, Amendment 39-17818 (79 FR 21385, April 16, 2014), for certain serial-numbered Sikorsky Model S92A helicopters. AD 2014-07-04 required repetitively inspecting the upper deck area for incorrectly installed clamps and chafing between the electrical wires and the hydraulic lines, replacing any unairworthy wires or hydraulic lines, and correcting any clamps that were installed incorrectly. Due to typographical errors when the AD was published, an incorrect serial number and an incorrect reference to the service information appeared in the text of the rule. On August 21, 2014, we issued AD 2014-07-04R1, Amendment 39-17964 (79 FR 54893, September 15, 2014), to correct these errors. Actions Since AD 2014-07-04R1 Was Issued Since we issued AD 2014-07-04R1 (79 FR 54893, September 15, 2014), Sikorsky has developed an alteration to correct the unsafe condition described in AD 2014-07-04R1. The alteration creates separate engine inlet and alternating current (AC) generator feeder lines, which were previously combined as an assembly. The new engine inlet feeder lines are rerouted through the cabin to the AC power distributors. The alteration also involves removing certain hydraulic to electrical clamps, which support the top deck main harnesses, and adding independent electrical brackets to create greater separation from the hydraulic lines. These proposed actions are intended to alter the wiring installation in the upper deck to prevent chafing between the electrical lines and hydraulic hoses. This condition, if not prevented, could result in a fire in an area of the helicopter without extinguishing capability and subsequent loss of control of the helicopter. FAA's Determination We are proposing 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 this same type design. Related Service Information Under 1 CFR Part 51 Sikorsky has issued Special Service Instructions SSI No. 92-070A, Revision A, dated April 25, 2014 (SSI 92-070A), which contains procedures to alter the wiring system in the upper deck area to prevent chafing. This service information is reasonably available because the interested parties have access to it through their normal course of business or by means identified in the Addresses Section of this proposed AD. Other Related Service Information We also reviewed Alert Service Bulletin ASB 92-20-003, Basic Issue, dated May 5, 2014 (ASB 92-20-003). ASB 92-20-003 specifies a one-time modification of the upper deck wiring harnesses to prevent possible chafing by complying with SSI 92-070A. Proposed AD Requirements This proposed AD would require altering the wiring system in the upper deck area. Differences Between This Proposed AD and the Service Information The service information provides a compliance date of November 5, 2015; the proposed AD would require a compliance time of 150 hours TIS. Also, the service information requires submitting certain documentation to the manufacturer, and the proposed AD would not. Costs of Compliance We estimate that this proposed AD would affect 20 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. Rerouting the upper deck wiring system and replacing and installing new parts would take 58 work hours and $8,000 in required parts, for a total cost of $12,930 per helicopter and $258,600 for the 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.
