1 [Federal Register Volume 82, Number 225 (Friday, November 24, 2017)] [Rules and Regulations] [Pages ] From the Federal Register Online via the Government Publishing Office [ [FR Doc No: ] DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA ; Product Identifier 2017-NM-092-AD; Amendment ; AD ] RIN 2120-AA64 Airworthiness Directives; ATR GIE Avions de Transport Régional Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. SUMMARY: We are adopting a new airworthiness directive (AD) for certain ATR GIE Avions de Transport Régional Model ATR airplanes and Model ATR72-212A airplanes. This AD requires an inspection for routing attachments of electrical harness bundles and for wire damage, and corrective actions if necessary. This AD was prompted by reports of electrical harness bundle chafing with a window blinding panel in the fuselage due to missing routing attachments. We are issuing this AD to address the unsafe condition on these products. DATES: This AD becomes effective December 11, The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of December 11, We must receive comments on this AD by January 8, ADDRESSES: You may send comments, using the procedures found in 14 CFR and 11.45, by any of the following methods: Federal erulemaking Portal: Go to Follow the instructions for submitting comments.

FOR FURTHER INFORMATION CONTACT: Shahram Daneshmandi, Aerospace Engineer, International Section, Transport Standards Branch, FAA, 1601 Lind Avenue SW., Renton, WA ; telephone ; fax SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive , dated July 7, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or the MCAI ), to correct an unsafe condition for certain ATR GIE Avions de Transport Régional Model ATR airplanes and Model ATR72-212A airplanes. The MCAI states: An event was reported of several spurious alarms on a recently delivered ATR 72 aeroplane. During troubleshooting, damage was evidenced on the electrical harness bundle (Route 1M) due to chafing with a window blinding panel located on the left hand of the fuselage, zone 231. A bracket, necessary to maintain the harness bundle close to the structure of the fuselage and avoid chafing, was missing. Same bracket has also been found missing on the other side of the fuselage (symmetrical location, Right Hand side, zone 232, route 2M) with no damage on the harness bundle. A quality investigation revealed another aeroplane on the production line, where same brackets were not installed. This condition, if not detected and corrected, may lead to wire failure (cut or shorted) and, in case of several failures in combination, the loss of systems, possibly resulting in reduced control of the aeroplane. To address this potential unsafe condition, ATR published Service Bulletin (SB) ATR and SB ATR to provide instructions to verify the installation of the brackets and to inspect the wire bundles [for damage e.g., but not limited to, chafing and electrical shorting]. 2
3 For the reasons described above, this [EASA] AD requires a one-time [detailed] inspection of the routing attachments [for missing attachments and wire damage] and, depending on findings, installation of the brackets and, as necessary, wire repair. You may examine the MCAI on the Internet at by searching for and locating Docket No. FAA Related Service Information Under 1 CFR Part 51 ATR has issued Service Bulletin ATR , dated May 3, 2017, for Model ATR42 airplanes; and Service Bulletin ATR , dated May 3, 2017, for Model ATR72 airplanes. This service information describes procedures for doing an inspection of routing attachments of electrical harness bundles and for wire damage, and corrective actions if necessary. 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. FAA's Determination and Requirements of This AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type designs. FAA's Determination of the Effective Date There are currently no domestic operators of this product. Therefore, we find good cause that notice and opportunity for prior public comment are unnecessary. In addition, for the reason(s) stated above, we find that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include Docket No. FAA ; Product Identifier 2017-NM-092-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments. We will post all comments we receive, without change, to including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance Currently, there are no affected U.S.-registered airplanes. If an affected airplane is imported and placed on the U.S. Register in the future, we provide the following cost estimates to comply with this AD. We estimate that it will take about 3 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $0, or $255 per product. 3
4 In addition, we estimate that any necessary follow-on actions will take about 1 work-hour and require parts costing $6, for a cost of $91 per product. We have no way of determining the number of aircraft that might need these actions. 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. Regulatory Findings We determined that this AD will not have federalism implications under Executive Order 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 the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska; 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.
