Airworthiness Directives; General 

Electric Company Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

General Electric Company (GE) GEnx-1B 

engines. This 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 AD requires removal of an affected 

extension duct and replacing it with a 

part eligible for installation. We are 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective August 30, 

2018.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all GE GEnx-1B engines. The 

NPRM published in the Federal 

Register on April 30, 2018 (83 FR 

18747). The NPRM was prompted by 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 assembly and overpressurization of 

the CVT. The NPRM proposed to require 

removal of an affected extension duct 

and replacing it with a part eligible for 

installation. We are issuing this AD to 

address the unsafe condition on these 

products. 

Comments 

We gave the public the opportunity to 

participate in developing this final rule. 

We have considered the comments 

received. The Air Line Pilots 

Association and United Airlines 

supported the NPRM. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this 

final rule as proposed. 

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. 

Costs of Compliance 

We estimate that this AD affects 97 

engines installed on airplanes of U.S. 

registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement of Extension Duct ..................... 4 work-hours × $85 per hour = $340 ............. $16,270 $16,610 $1,611,170 

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.

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. 

(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.

Withdrawal for Designated Facilities 

and Pollutants 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is approving Ohio’s 

request for withdrawal of the previously 

approved Hospital/Medical/Infectious 

Waste Incinerator (HMIWI) State Plan. 

The Ohio Environmental Protection 

Agency (OEPA) submitted its HMIWI 

withdrawal on January 24, 2018, 

certifying that there is only one HMIWI 

unit currently operating in the state of 

Ohio and requesting that the Federal 

Plan apply to the single source in the 

State. The Federal HMIWI Plan will 

therefore apply in Ohio. 

DATES: This final rule is effective on 

August 27, 2018. 

ADDRESSES: EPA has established a 

docket for this action under Docket ID 

No. EPA–R05–OAR–2018–0113. All
