Federal Register Abstract
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.

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
Administrator, the FAA amends part 39 of the Federal Aviation
Regulations (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)
2015-04-03, Amendment 39-18105 (80 FR 9380, February 23, 2015) (``AD
2015-04-03''), and adding the following new AD:
2016-04-13 Rolls-Royce plc: Amendment 39-18407; Docket No. FAA-2014-
0561; Directorate Identifier 2014-NE-12-AD.
(a) Effective Date
This AD is effective April 19, 2016.
(b) Affected ADs
This AD supersedes AD 2015-04-03.
(c) Applicability
This AD applies to Rolls-Royce plc (RR) RB211 Trent 768-60, 772-
60, and 772B-60 turbofan engines, all serial numbers, except those
engines:
(1) That have had Modification 72-H754 applied in production, or
(2) that have been modified in accordance with RR Service
Bulletin (SB) No. RB.211-72-H754, including the Supplement, Revision
1, dated July 29, 2015 or initial issue dated October 1, 2014; or
(3) with sealing sleeve, part number (P/N) FW15003, with
markings 102013, 112013, or 102013L.
(d) Unsafe Condition
This AD was prompted by fractures of the high-pressure/
intermediate pressure (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.
(e) Compliance

unless already done.
(1) If sealing sleeve, P/N FW15003, is installed without
markings 102013, 112013, or 102013L, or if the markings cannot be
sufficiently identified, then within 1,600 flight cycles or 24
months after the effective date of this AD, whichever occurs first:
(i) Remove the affected sealing sleeve, P/N FW15003, and replace
it with a part eligible for installation. Use paragraph 3.A.(4)(b)
of RR Alert Non-Modification Service Bulletin No. RB.211-72-AJ035,
Revision 2, dated August 10, 2015, to perform the part replacement,
or,
