AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Final rule. 

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 of the sealing sleeve on the highpressure/intermediate-pressure (HP/IP) turbine support internal oil feed tube and removal 

of those sealing sleeves affected by AD 2015-04-03. This AD requires removal of either 

the affected sealing sleeve only or both the affected sealing sleeve and the oil feed tube. 

This AD was prompted by fractures of the HP/IP turbine support internal oil feed tube. 

We are issuing this AD to prevent failure of the I-IP/IP turbine support internal oil feed 

tube, uncontained engine failure, and damage to the airplane. 

DATES: This AD is effective [INSERT DATE 35 DAYS AFTER DATE OF 

PUBLICATION lN THE FEDERAL REGISTER]. 
The Director of the Federal Register approved the incorporation by reference of 

certain publications listed in tl1is AD as of [INSERT DATE 35 DAYS AFTER DATE OF 

PUBLICATION IN THE FEDERAL REGISTER].

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 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 specified products. The NPRM 

published in the Federal Register on November 10,2015 (80 FR 69625). The NPRM 

proposed to require removal of either the affected sealing sleeve only or both the affected 

sealing sleeve and the oil feed tube. 

Comments 

We gave the public the opportunity to participate in developing this AD. We 

considered the comment received. The cornmenter supports the NPRM (80 FR 69625, 

November 10, 2015). 

Conclusion 

We reviewed the available data, including the comment received, and determined 

that air safety and the public interest require adopting this AD as proposed. 

Related Service Information under 1 CFR Part 51 

RR has issued RR Alert Non-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 Alert NMSB 

No. RB.211-72-AJ035, Revision 2, dated August 10,2015, provides guidance on 

identification and replacement of the sealing sleeve, part number (PIN) FW15003. The 

3 
SB No. RB.211-72-H754, including the Supplement, Revision I, dated July 29, 2015, 

provides information on the replacement of the 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 because the interested parties 

have access to it through their nmmal course of business or by the means identified in the 

ADDRESSES section of this AD. 

Costs of Compliance 

We estimate that this AD affects 58 engines installed on airplanes of U.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 $5,850 per engine. Based on 

these figures, we estimate the cost of this AD on U.S. operators to be $345,216. 

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, 

Prut 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. 

4 
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.
