Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2014-0561; Directorate Identifier 2014-NE-12-AD; 
Amendment 39-18407; AD 2016-04-13]
RIN 2120-AA64

Airworthiness Directives; Rolls-Royce plc Turbofan Engines

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 high-pressure/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 HP/IP turbine support internal oil feed tube, 
uncontained engine failure, and damage to the airplane.

DATES: This AD is effective April 19, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 19, 
2016.

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 commenter 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 1, 
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 (P/N) FW15003. The SB 
No. RB.211-72-H754, including the Supplement, Revision 1, dated July 
29, 2015, provides information on the replacement of the sealing 
sleeve, P/N FW15003, and oil feed tube, P/N FW14193, with a sealing 
sleeve, P/N KH28323 and oil feed tube, P/N KH28324. 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 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 with 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, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in

[[Page 13714]]

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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the
