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 certain 

General Electric Company (GE) GEnx– 

2B67, –2B67B, and –2B67/P turbofan 

engines. This proposed AD was 

prompted by low-cycle fatigue (LCF) 

cracking of the fuel manifold leading to 

an engine fire. This proposed AD would 

require removal from service of certain 

fuel manifolds at the next engine shop 

visit and their replacement with parts 

eligible for installation. We are 

proposing this AD to address the unsafe 

condition on these products. 

DATES: We must receive comments on 

this proposed AD by September 17, 

2018. 

ADDRESSES: You may send comments,

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 received information concerning a 

fire in the under-cowl compartment of 

a GE GEnx–2B turbofan engine. 

Insufficient bushing clearance in the 

fuel manifold bracket resulted in 

additional fuel manifold loads, 

premature manifold cracking, fuel 

leakage, and fuel ignition. Twelve fuel 

manifolds were found to have LCF 

cracks. Three of these twelve cracked 

fuel manifolds resulted in a fire. This 

condition, if not addressed, could result 

in failure of the fuel manifold, engine 

fire, and damage to the airplane. 

Related Service Information 

We reviewed GE GEnx–2B Service 

Bulletin (SB) 73–0038 R02, dated 

November 19, 2015. The SB describes 

procedures for removing and replacing 

the fuel manifold system with parts 

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 from service of certain fuel 

manifolds at the next engine shop visit 

and their replacement with parts 

eligible for installation. 

Costs of Compliance 

We estimate that this proposed AD 

affects two engines installed on 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replace fuel manifolds ................................... 220 work-hours × $85 per hour = $18,700 .... $119,485 $138,185 $276,370 

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: 

PART 39—AIRWORTHINESS 

DIRECTIVES

pressure relief valve (PRV) of the 

hydraulic reservoir (HR) due to the 

extrusion of the O-ring seal from certain 

HR PRVs. This proposed AD would 

require identifying the part number of 

the HR, and replacing and re-identifying

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2018–0064, dated March 23, 

2018 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for all Airbus SAS 

Model A330–200 Freighter, –200 and 

–300 series airplanes; and Airbus SAS 

Model A340–200, –300, –500, and –600 

series airplanes. The MCAI states: 

Some events of depressurisation of 

hydraulic reservoirs have been reported, due 

to air leakage from the HR PRV [hydraulic 

reservoir pressure relief valve]. The results of 

the investigations revealed that the air 

leakage was due to the extrusion of the 

O-ring seal from the HR PRV. This may have
