[Federal Register Volume 81, Number 235 (Wednesday, December 7, 2016)] [Proposed Rules] [Pages 88143-88145] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-28670] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2016-6436; Directorate Identifier 2015-SW-037-AD] RIN 2120-AA64 Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB- BK117 C-2 helicopters. This proposed AD would require inspecting the pilot collective wiring harness. This proposed AD is prompted by a report that a heat-shrinkable sleeve prevented the twist grip on the collective from being fully engaged during a flight test. The proposed actions are intended to prevent failure of the hoist or emergency landing gear flotation systems due to chafing of wiring caused by an incorrectly installed heat-shrinkable sleeve. DATES: We must receive comments on this proposed AD by February 6, 2017. 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.

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 proposal in light of the comments we receive. Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2015-0144, dated July 21, 2015, to correct an unsafe condition for Airbus Helicopters Model MBB-BK117 C-2 helicopters, up to serial number 9708. EASA advises that, during a flight test, the pilot could not fully engage a twist grip on a Model MBB-BK117 C-2 helicopter. According to EASA, further investigation found a transparent sleeve on the collective lever wiring harness damaged because of incorrect installation of the heat-shrinkable sleeve. This condition, if not detected and corrected, could result in chafing of the harness, leading to the malfunction of the affected systems, EASA advises. EASA consequently requires a one-time inspection of the heat-shrinkable and transparent sleeves installed on the collective lever wiring harness. FAA's Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information Under 1 CFR Part 51 We reviewed Airbus Helicopters Alert Service Bulletin ASB MBB-BK117 C-2-88A-010, Revision 1, dated April 16, 2015 (ASB), which specifies a visual inspection of the heat-shrinkable sleeve for correct position. If the sleeve's position is incorrect, the ASB specifies shortening the sleeve. If there is any damage, the ASB calls for replacing the damaged parts. 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. Proposed AD Requirements This proposed AD would require, within 100 hours time-in-service, visually inspecting the pilot collective wiring harness for correct position of the heat-shrinkable sleeve and the transparent sleeve. If the heat-shrinkable and the transparent sleeves are in their correct positions, this proposed AD would require re-installing the collective lever. If the heat-shrinkable sleeve is closer to or below the torque tube tangs, this proposed AD would require shortening the heat- shrinkable sleeve. If the transparent sleeve is damaged, this proposed AD would require replacing the heat-shrinkable sleeve, transparent sleeve, and identification sleeve. Lastly, this proposed AD would require replacing any damaged wires in the wiring harness. Differences Between This Proposed AD and the TCCA AD The compliance time in the EASA AD is based on whether the helicopter has an externally mounted hoist or emergency flotation system. This proposed AD would require compliance within 100 hours time-in-service for all applicable helicopters. Costs of Compliance We estimate that this proposed AD would affect 113 helicopters of U.S. Registry and that labor costs average $85 a work hour. Inspecting the pilot collective wiring harness for the correct position of the heat-shrinkable sleeve would require 1.5 work hours. No parts would be required for a total cost of $128 per helicopter and $14,464 for the U.S. fleet. Replacing or repairing the sleeves would require 5.5 work hours and parts would cost $10, for a total cost of $478 per helicopter. 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 [[Page 88145]] 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.
