SUMMARY: We are superseding airworthiness directive (AD) 2015-04-03 that applies to certain Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. AD 2015-04-03 required inspection ofthe sealing sleeve onthe highpressure/intermediate-pressure (HP/IP) turbine support internal oil feed tube and removal ofthose sealing sleeves affected by AD 2015-04-03. This AD requires removal ofeither the affected sealing sleeve only or both the affected sealing sleeve and the oil feed tube. This AD was promptedby fractures ofthe HP/IP turbine support internal oil feed tube. We are issuing this AD to prevent failure ofthe I-IP/IP turbine support internal oil feed tube, uncontained engine failure, and damage to the airplane.

### SUPPLEMENTARY INFORMATION: Discussion We issued a notice ofproposed rulemaking (NPRM) to amend 14 CFRpart 39 to supersede AD 2015-04-03, Amendment 39-18105 (80 FR 9380, February 23, 2015), ("AD 2015-04-03"). AD 2015-04-03 applied to the specifiedproducts. The NPRM published in the Federal Register on November 10,2015 (80 FR 69625). TheNPRM proposedto require removal ofeitherthe affected sealing sleeve only or boththe affected sealing sleeve and the oil feed tube. Comments We gave the public the opportunity to participate in developing this AD. We consideredthe comment received. The cornmenter supports the NPRM (80 FR 69625, November 10, 2015). Conclusion We reviewed the available data, including the commentreceived, and determined that air safety and the public interestrequire adopting this AD as proposed. Related Service Information under 1 CFR Part 51 RRhas issued RR AlertNon-Modification Service Bulletin (NMSB) No. RB.211- 72-AJ035, Revision 2, dated August 10, 2015 and RR Service Bulletin (SB) No. RB.211- 72-H754, including the Supplement, Revision l, dated July 29, 2015. The AlertNMSB No. RB.211-72-AJ035, Revision 2, dated August 10,2015, provides guidance on identification and replacement ofthe sealing sleeve, part number (PIN) FW15003. The

3SB No. RB.211-72-H754, includingthe Supplement, Revision I, dated July 29, 2015, provides information onthe replacement ofthe sealing sleeve, 

### PIN FW15003, and oil feed tube, 

### PIN FW14193, with a sealing sleeve, 

### PIN KH28323 and oil feed tube, 

### PIN KH28324. This service information is reasonably available becausethe interestedparties have access to it through their nmmal course ofbusiness or

### by the means identified in the ADDRESSES section ofthis AD. Costs ofCompliance We estimate thatthis AD affects 58 engines installed on airplanes ofU.S. registry. We also estimate that 

### it will take about 1.2 hours per engine to comply vvith this AD. The average labor rate is $85 per hour. Required parts cost about $5,850per engine. Based on these figures, we estimate the cost ofthis AD on U.S. operators to be $345,216. Authority for this Rulemaking Title 49 ofthe United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority ofthe FAAAdministrator. Subtitle VII, Aviation Programs, describes in more detail the scope ofthe Agency's authority. We are issuingthis rulemaking under the authority described in Subtitle VII, PrutA, Subpart III, Section 44701, "General requirements." Underthat section, Congress charges the FAA withpromoting safe flight ofcivil 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 ofthat authority because it addresses an unsafe condition that is likely to exist or develop onproducts identified in this rulemaking action.
