We are superseding Airworthiness Directive (AD) 2013-02-04 for all Rolls-Royce plc (RR) RB211-Trent 970-84, RB211-Trent 970B-84, RB211-Trent 972-84, RB211-Trent 972B-84, RB211-Trent 977-84, RB211- Trent 977B-84, and RB211-Trent 980-84 turbofan engines. AD 2013-02-04 required on-wing inspections of low-pressure turbine (LPT) disk seal fins and interstage seals when post-flight review indicates Engine Health Monitoring (EHM) vibratory maintenance-alert limits were exceeded in flight. This AD requires additional criteria for the inspection of the stage 2, 3, and 4 LPT disk seal fins and interstage seals and removes the requirement to inspect the stage 5 LPT disk seal fins and interstage seal. This AD was prompted by a Trent 900 engine experiencing increased low-pressure rotor vibration while in flight resulting in an in-flight shutdown (IFSD) and air turnback. We are issuing this AD to address 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) 2013-02-04 for 
all Rolls-Royce plc (RR) RB211-Trent 970-84, RB211-Trent 970B-84, 
RB211-Trent 972-84, RB211-Trent 972B-84, RB211-Trent 977-84, RB211-
Trent 977B-84, and RB211-Trent 980-84 turbofan engines. AD 2013-02-04 
required on-wing inspections of low-pressure turbine (LPT) disk seal 
fins and interstage seals when post-flight review indicates Engine 
Health Monitoring (EHM) vibratory maintenance-alert limits were 
exceeded in flight. This AD requires additional criteria for the 
inspection of the stage 2, 3, and 4 LPT disk seal fins and interstage 
seals and removes the requirement to inspect the stage 5 LPT disk seal 
fins and interstage seal. This AD was prompted by a Trent 900 engine 
experiencing increased low-pressure rotor vibration while in flight 
resulting in an in-flight shutdown (IFSD) and air turnback. We are 
issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued AD 2013-02-04, Amendment 39-17325 (78 FR 6206, January 
30, 2013), (``AD 2013-02-04''), for all RR RB211-Trent 970-84, RB211-
Trent 970B-84, RB211-Trent 972-84, RB211-Trent 972B-84, RB211-Trent 
977-84, RB211-Trent 977B-84, and RB211-Trent 980-84 turbofan engines. 
AD 2013-02-04 required on-wing inspections of LPT disk seal fins and 
interstage seals when post-flight review indicates EHM vibratory 
maintenance-alert limits were exceeded in flight. AD 2013-02-04 also 
required in-shop inspections of the LPT disk seal fins and interstage 
seals to detect cracks or damage and, depending on the findings, 
accomplishment of corrective action. AD 2013-02-04 resulted from a 
Trent 900 engine experiencing LPT stage 2 disk interstage seal material 
loss and increased low-pressure rotor (N1) vibration while in flight. 
We issued AD 2013-02-04 to prevent cracks in the LPT disk, which could 
result in uncontained engine failure and damage to the airplane.

Actions Since AD 2013-02-04 Was Issued

    Since we issued AD 2013-02-04, a Trent 900 engine experienced 
increased N1 vibration while in flight resulting in an IFSD and air 
turnback. Inspection of the engine revealed LPT damage. A subsequent 
review of the potential causes determined that engine overhaul shop 
visit activities could be a factor. RR issued Revision 2 to Alert Non-
Modification Service Bulletin (NMSB) RB.211-72-AH054 to introduce an 
inspection of the LPT disk seal fins and interstage seals after an 
overhaul shop visit when an engine test (pass-off test) is required due 
to the work performed. RR also published Revision 3 to Alert NMSB 
RB.211-72-AH054, dated February 1, 2018, to remove engines that have 
incorporated the modifications introduced by RR Alert SB RB.211-72-
AJ592, dated September 4, 2017, from its applicability. In addition, 
the European Aviation Safety Agency (EASA) published AD 2018-0126, 
dated June 11, 2018, to require the changes introduced by Revision 3 of 
RR Alert NMSB RB.211-72-AH054. We are issuing this AD to address the 
unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    We reviewed RR issued Alert NMSB RB.211-72-AH054, Revision 3, dated 
February 1, 2018. The Alert NMSB describes procedures for inspection 
after a pass-off test. 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.

FAA's Determination

    This product has been approved by EASA and is approved for 
operation in the United States. Pursuant to our bilateral agreement 
with the European Community, EASA has notified us of the unsafe 
condition described in the MCAI and service information referenced 
above. 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 partially retains the requirements of AD 2013-02-04, 
requires inspection of the LPT disk seal fins and interstage seals 
following pass-off test, and changes certain inspection requirements.

FAA's Justification and Determination of the Effective Date

    No domestic operators use this product. Therefore, we find good 
cause that notice and opportunity for prior public comment are 
unnecessary. In addition, for the reason stated above, we find that 
good cause exists for making this amendment effective in less than 30 
days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. 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 
the docket number FAA-2017-1122 and product identifier 2012-NE-42-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.

Costs of Compliance

    We estimate that this AD affects 0 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

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, 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.
