[Federal Register Volume 81, Number 231 (Thursday, December 1, 2016)] [Proposed Rules] [Pages 86630-86633] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-27923] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2014-0363; Directorate Identifier 2014-NE-08-AD] RIN 2120-AA64 Airworthiness Directives; Rolls-Royce plc Turbofan Engines AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede airworthiness directive (AD) 2015-17- 19 that applies to all Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. AD 2015-17-19 requires inspection of the fan case low-pressure (LP) fuel tubes and associated clips and the fuel oil heat exchanger (FOHE) mounts and associated hardware. Since we issued AD 2015-17-19, fractures on the LP fuel return tube at mid-span locations were found with resulting fuel leaks. This proposed AD would require a modification, which terminates the repetitive inspections. We are proposing this AD to prevent failure of the fan case LP fuel tubes, which could lead to an in-flight shutdown, loss of thrust control, and damage to the airplane. DATES: We must receive comments on this proposed AD by January 30, 2017. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On August 20, 2015, we issued AD 2015-17-19, Amendment 39-18252 (80 FR 55232, September 15, 2015), (``AD 2015-17-19'') for RR RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. AD 2015-17-19 requires inspection of the fan case LP fuel tubes and associated clips and the FOHE mounts and associated hardware. AD 2015-17-19 resulted from fuel leaks caused by damage to the fan case LP fuel tube. We issued AD 2015- 17-19 to prevent failure of the fan case LP fuel tube, which could lead to an in-flight shutdown, loss of thrust control, and damage to the airplane. Actions Since AD 2015-17-19 Was Issued Since we issued AD 2015-17-19, fractures on the LP fuel return tube at mid-span locations were found with resulting fuel leaks. Also since we issued AD 2015-17-19, the European Aviation Safety Agency (EASA) has issued AD 2016-0120, dated June 17, 2016, which supersedes EASA AD 2014-0243, Revision 1, dated December 10, 2014 and Correction, dated March 23, 2015. Related Service Information Under 1 CFR Part 51 RR has issued Alert Non-Modification Service Bulletin (NMSB) RB.211-73-AH522, Revision 4, dated January 18, 2016; Alert NMSB RB.211- 73-AH837, Revision 1, dated November 6, 2015; and Alert Service Bulletin (ASB) RB.211-73-AJ366, Initial Issue and Supplement, dated May 3, 2016. Alert NMSB RB.211-73-AH522, Revision 4, dated January 18, 2016 describes procedures for inspecting and, if necessary, replacing worn rubber sections of the P-clip. Alert NMSB RB.211-73-AH837, Revision 1, dated November 6, 2015 describes procedures for inspecting and, if necessary, replacing the P-clip attaching bracket, supporting hardware, and low-pressure (LP) fuel tube.Alert SB RB.211-73-AJ366, Initial Issue and Supplement, dated May 3, 2016 describes procedures for modification of the routing of fuel, oil, and hydraulic tube assemblies. 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 RR has issued SB RB.211-73-F343, Revision 4, dated May 26, 2011. The service information describes procedures for replacing the fuel tube assemblies and supporting hardware. 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 these same type designs. Proposed AD Requirements This proposed AD would retain the requirements of AD 2015-17-19, (80 FR 55232, September 15, 2015), except it would require a modification, which terminates the repetitive inspections. This proposed AD would add a mandatory terminating action to the repetitive inspections by incorporating ASB RB.211-73-AJ366, Initial Issue and Supplement, dated May 3, 2016. Costs of Compliance We estimate that this proposed AD affects 108 engines installed on airplanes of U.S. registry. We also estimate that it would take about 6 hours per engine to perform the inspections in this proposed AD. The average labor rate is $85 per hour. We also estimate that 54 of the engines will fail the inspections required by this AD. Replacement parts cost about $4,031 per engine. We also estimate that it would take about 50 hours per engine to modify each engine. The modification would cost about $150,000 per engine. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $16,931,754. 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 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 86632]] responsibilities among the various levels of government. For the reasons discussed above, I certify that the 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. 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. 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 removing airworthiness directive (AD) 2015-17-19, Amendment 39-18252 (80 FR 55232, September 15, 2015), and adding the following new AD: Rolls-Royce plc: Docket No. FAA-2014-0363; Directorate Identifier 2014-NE-08-AD. (a) Comments Due Date We must receive comments by January 30, 2017. (b) Affected ADs This AD supersedes AD 2015-17-19, Amendment 39-18252 (80 FR 55232, September 15, 2015).
