AGENCY:
Examining the AD Docket
We are superseding
airworthiness directive (AD) 2013–05–
18 for certain Rolls-Royce plc (RR)
RB211 Trent 500 series turbofan
engines. AD 2013–05–18 required initial
and repetitive inspections of the lowpressure (LP) fuel tubes, fuel tube clips,
and fuel/oil heat exchanger (FOHE)
mounts for evidence of damage, wear,
and fuel leakage. This AD reduces the
repetitive inspection intervals. This AD
was prompted by additional service
experience. We are issuing this AD to
correct the unsafe condition on these
products.

This AD is effective March 17,
2017.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of March 17, 2017.
We must receive any comments on
this AD by May 1, 2017.

Discussion
On March 7, 2013, we issued AD
2013–05–18, Amendment 39–17390 (78
FR 17297, March 21, 2013), for all RR
RB211 Trent 500 series turbofan
engines. AD 2013–05–18 required initial
and repetitive inspections of the fuel
tubes, fuel tube clips, and FOHE mounts
for evidence of damage, wear, and fuel
leakage. AD 2013–05–18 resulted from
reports of wear found between the
securing clips and the LP fuel tube outer
surface, which reduces the fuel tube
wall thickness, leading to fracture of the
fuel tube and consequent fuel leakage.
We issued AD 2013–05–18 to prevent
engine fuel leaks, which could result in
engine damage and damage to the
airplane.
Actions Since AD 2013–05–18 Was
Issued
Since we issued AD 2013–05–18, RR
has determined that the repetitive
inspection interval should be reduced.
Also since we issued AD 2013–05–18,
the European Aviation Safety Agency
(EASA) has issued AD 2016–0227, dated
November 10, 2016, which requires
correcting some technical instructions
and reducing the inspection interval.
Related Service Information Under
1 CFR Part 51
We reviewed RR Alert Non
Modification Service Bulletin (NMSB)
RB.211–73–AG948, Revision 3, dated
September 9, 2016. The NMSB describes
procedures for inspecting, removing,
and replacing the LP fuel tubes, fuel
tube clips, and FOHE mounts. This
service information is reasonably
E:\FR\FM\02MRR1.SGM
02MRR1
12290
Federal Register / Vol. 82, No. 40 / Thursday, March 2, 2017 / Rules and Regulations
available because the interested parties
have access to it through their normal
course of business or by the means
identified in the ADDRESSES section.
FAA’s Determination
We are issuing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
AD Requirements
This AD requires repetitive
inspections of the LP fuel tubes and fuel
tube clips, and FOHE mounts for
evidence of damage, wear, and fuel
leakage.
FAA’s Justification and Determination
of the Effective Date
No domestic operators use this
product. Therefore, we find that notice
and opportunity for prior public
comment are unnecessary and that good
cause exists for making this amendment
effective in less than 30 days.
Costs of Compliance
We estimate that this AD affects no
engines installed on airplanes of U.S.
registry.
We estimate the following costs to
comply with this AD:

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

the ADDRESSES section. Include ``Docket No. FAA-2012-0004; Directorate
Identifier 2012-NE-01-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We

Discussion
On March 7, 2013, we issued AD 2013-05-18, Amendment 39-17390 (78
FR 17297, March 21, 2013), for all RR RB211 Trent 500 series turbofan
engines. AD 2013-05-18 required initial and repetitive inspections of
the fuel tubes, fuel tube clips, and FOHE mounts for evidence of
damage, wear, and fuel leakage. AD 2013-05-18 resulted from reports of
wear found between the securing clips and the LP fuel tube outer
surface, which reduces the fuel tube wall thickness, leading to
fracture of the fuel tube and consequent fuel leakage. We issued AD
2013-05-18 to prevent engine fuel leaks, which could result in engine
damage and damage to the airplane.
Actions Since AD 2013-05-18 Was Issued
Since we issued AD 2013-05-18, RR has determined that the
repetitive inspection interval should be reduced. Also since we issued
AD 2013-05-18, the European Aviation Safety Agency (EASA) has issued AD
2016-0227, dated November 10, 2016, which requires correcting some
technical instructions and reducing the inspection interval.
Related Service Information Under 1 CFR Part 51
We reviewed RR Alert Non Modification Service Bulletin (NMSB)
RB.211-73-AG948, Revision 3, dated September 9, 2016. The NMSB
describes procedures for inspecting, removing, and replacing the LP
fuel tubes, fuel tube clips, and FOHE mounts. This service information
is reasonably
[[Page 12290]]
available because the interested parties have access to it through
their normal course of business or by the means identified in the
ADDRESSES section.
FAA's Determination
We are issuing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
AD Requirements
This AD requires repetitive inspections of the LP fuel tubes and
fuel tube clips, and FOHE mounts for evidence of damage, wear, and fuel
leakage.
FAA's Justification and Determination of the Effective Date
No domestic operators use this product. Therefore, we find that
notice and opportunity for prior public comment are unnecessary and
that good cause exists for making this amendment effective in less than
30 days.
Costs of Compliance
We estimate that this AD affects no engines installed on airplanes
of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.

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 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)
2013-05-18, Amendment 39-17390 (78 FR 17297, March 21, 2013), and
adding the following new AD:
2017-03-03 Rolls-Royce plc: Amendment 39-18794; Docket No. FAA-2012-
0004; Directorate Identifier 2012-NE-01-AD.
(a) Effective Date
This AD is effective March 17, 2017.
(b) Affected ADs
This AD supersedes AD 2013-05-18, Amendment 39-17390 (78 FR
17297, March 21, 2013).
(c) Applicability
This AD applies to Rolls-Royce plc (RR) RB211 Trent 553-61,
RB211 Trent 553A2-61, RB211 Trent 556-61, RB211 Trent 556A2-61,
