[[Page 55233]] ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. This AD was prompted by fuel leaks caused by damage to the fan case low-pressure (LP) fuel tube. This AD requires inspection of the fan case LP fuel tubes and associated clips and the fuel oil heat exchanger (FOHE) mounts and associated hardware. We are issuing this AD to prevent failure of the fan case LP fuel tube, which could lead to an in-flight engine shutdown, loss of thrust control, and damage to the airplane. DATES: This AD is effective October 20, 2015. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 20, 2015.

SUPPLEMENTARY INFORMATION: Discussion We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to all RR RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. The SNPRM published in the Federal Register on April 21, 2015 (80 FR 22137). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on July 3, 2014 (79 FR 37965). The NPRM proposed to require inspection of the fan case LP fuel tubes and associated clips and the FOHE mounts and associated hardware. The NPRM was prompted by fuel leaks caused by damage to the fan case LP fuel tube. We are issuing this AD to prevent failure of the fan case LP fuel tube, which could lead to an in-flight engine shutdown, loss of thrust control, and damage to the airplane. Related Service Information Under 1 CFR Part 51 We reviewed RR Alert Non-Modification Service Bulletin (NMSB) No. RB.211-73-AH522, Revision 2, dated July 18, 2014; and RR Alert NMSB No. RB.211-73-AH837, dated September 9, 2014. This service information describes procedures for inspecting, and replacing if required, the fan case LP fuel tube and clips and the FOHE mounts and hardware. This service information is reasonably available because the interested parties have access to it through their normal course of business or see ADDRESSES for other ways to access this service information. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM (80 FR 22137, April 21, 2015). Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed. Costs of Compliance We estimate that this AD affects about 50 engines installed on airplanes of U.S. registry. We also estimate that it will take about 6 hours per engine to comply with this AD. The average labor rate is $85 per hour. We also estimate that 25 of the engines will fail the inspection required by this AD. Required parts cost about $4,031 per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to be $126,275. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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. [[Page 55234]] Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2015-17-19 Rolls-Royce plc: Amendment 39-18252; Docket No. FAA-2014- 0363; Directorate Identifier 2014-NE-08-AD.
