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 low- pressure (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.

Airworthiness Directives; Rolls-Royce plc Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: 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 low-
pressure (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.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
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 http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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:

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.
