We propose to adopt a new airworthiness directive (AD) for all General Electric Company (GE) GEnx-1B engines. This proposed AD was prompted by a report of a center vent tube (CVT) failure leading to a loss of oil pressure and subsequent in-flight engine shutdown. This proposed AD would require removal of the Air/Oil Extension Ducts, part numbers (P/N) 2332M85P01 or 2331M25G03. We are proposing this AD to address the unsafe condition on these products.

[Docket No. FAA-2018-0224; Product Identifier 2018-NE-01-AD]


Airworthiness Directives; General Electric Company Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
General Electric Company (GE) GEnx-1B engines. This proposed AD was 
prompted by a report of a center vent tube (CVT) failure leading to a 
loss of oil pressure and subsequent in-flight engine shutdown. This 
proposed AD would require removal of the Air/Oil Extension Ducts, part 
numbers (P/N) 2332M85P01 or 2331M25G03. We are proposing this AD to 
address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2018-0224; 
Product Identifier 2018-NE-01-AD'' at the beginning of your comments. 
We specifically invite comments on the overall regulatory, economic,

comments received by the closing date and may amend this NPRM 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 NPRM.

Discussion

    We were prompted to issue this NPRM based upon a report of a CVT 
failure leading to a loss of oil pressure and subsequent in-flight 
engine shutdown. During the event, the CVT failed due to oil leaking 
into the fan mid shaft, resulting in coking on the seal

[[Page 18748]]

assembly and overpressurization of the CVT. This condition, if not 
addressed, could result in failure of one or more engines, loss of 
thrust control, and loss of the airplane.

Related Service Information

    We reviewed GE GEnx-1B Service Bulletin (SB) 72-0331 R01, dated 
August 21, 2017. The SB describes procedures for replacing air/oil 
extension ducts, P/N 2332M85P01 or 2331M25G03, with an extension duct 
eligible for installation.

FAA's Determination

    We are proposing 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.

Proposed AD Requirements

    This proposed AD would require removal of an affected extension 
duct and replacing it with a part eligible for installation.

Costs of Compliance

    We estimate that this proposed AD affects 97 engines installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed 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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

(d) Subject

    Joint Aircraft System Component (JASC) Code 7250, Turbine 
Section.

(e) Unsafe Condition

    This AD was prompted by reports of a center vent tube (CVT) 
failure. We are issuing this AD to prevent failure of the CVT. The 
unsafe condition, if not addressed, could result in failure of one 
or more engines, loss of thrust control, and loss of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    At the next engine shop visit after the effective date of this 
AD, remove air/oil extension ducts, P/N 2332M85P01 or 2331M25G03, 
and replace with a part eligible for installation.

(h) Definition

    For the purpose of this AD, an ``engine shop visit'' is the 
induction of an engine into the shop for maintenance involving the 
separation of pairs of major mating engine case flanges, except for 
the following situations, which do not constitute an engine shop 
visit:
    (1) Separation of engine flanges solely for the purposes of 
transportation of the engine without subsequent maintenance.
    (2) Separation of engine flanges solely for the purpose of 
replacing the fan or propulsor without subsequent maintenance.

[[Page 18749]]

(i) Installation Prohibition

    After the effective date of this AD, do not install an Air/Oil 
Extension Duct, P/N 2332M85P01 or 2331M25G03, into a fan mid shaft 
Assembly.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, ECO Branch, FAA, has the authority to approve 
AMOCs for this AD if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the manager of the 
certification office, send it to the attention of the person 
identified in paragraph (k)(1) of this AD.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
