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 turbofan engine models. This AD 

was prompted by reports of GEnx–1B 

engine oil loss. This AD requires 

removal and replacement of the nonconforming ball valve in the oil filler 

cap. We are issuing this AD to prevent 

loss of engine oil, which could lead to 

failure of one or more engines, loss of 

thrust control, and damage to the 

airplane. 

DATES: This AD is effective December 

17, 2015. 

ADDRESSES: For service information 

identified in this AD, contact General 

Electric Company, GE Aviation, Room 

285, 1 Neumann Way, Cincinnati, OH

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 turbofan 

engine models. The NPRM published in 

the Federal Register on June 17, 2015 

(80 FR 34560). The NPRM was 

prompted by multiple reports of engine 

oil loss and resultant flight plan 

diversions. The NPRM proposed to 

require removal and replacement of the 

non-conforming ball valve in the oil 

filler cap. We are issuing this AD to 

correct the unsafe condition on these 

products. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM (80 FR 34560, 

June 17, 2015) and the FAA’s response 

to each comment. 

Support for the NPRM 

One individual commenter expressed 

support for the NPRM (80 FR 34560, 

June 17, 2015). 

Request To Change Applicability 

American Airlines (American) 

requested that paragraph (c) 

Applicability be changed. American 

stated that the part number and the 

post-SB markings are located on the oil 

filler cap scupper not on the oil filler 

cap itself. American indicated that this 

change would improve clarity and 

accomplishment of the AD. 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 80, No. 218 / Thursday, November 12, 2015 / Rules and Regulations 69839 

We agree. We revised paragraph (c), 

Applicability, of this AD to read: ‘‘This 

AD applies to all General Electric 

Company (GE) GEnx–1B model turbofan 

engines with oil filler cap, part number 

(P/N) 2349M62G01, installed, that do 

not contain any of the following 

markings after the P/N on the oil filler 

cap scupper: ‘‘P/M BALL PP,’’ or ‘‘RW,’’ 

or ‘‘79–0022.’’ 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this AD 

with the change described previously. 

We determined that this change will not 

increase the economic burden on any 

operator or increase the scope of this 

AD. 

Related Service Information 

We reviewed GE GEnx–1B Service 

Bulletin (SB) No. 79–0022, Revision 1, 

dated May 13, 2015. The SB describes 

procedures for removing and replacing 

the ball valve in the oil filler cap. 

Costs of Compliance 

We estimate that this AD affects 86 

engines installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 1 hour per engine to comply 

with this AD. The average labor rate is 

$85 per hour. Required parts cost about 

$11 per engine. Based on these figures, 

we estimate the cost of the AD to U.S. 

operators to be $8,256. 

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, 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.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

2015–23–04 General Electric Company: 

Amendment 39–18320; Docket No. 

FAA–2015–1658; Directorate Identifier 

2015–NE–18–AD. 

(a) Effective Date 

This AD is effective December 17, 2015. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all General Electric

contain any of the following markings after 

the P/N on the oil filler cap scupper: ‘‘P/M 

BALL PP,’’ or ‘‘RW,’’ or ‘‘79–0022.’’ 

(d) Unsafe Condition 

This AD was prompted by reports of 

GEnx–1B engine oil loss. We are issuing this 

AD to prevent loss of engine oil, which could 

lead to failure of one or more engines, loss 

of thrust control, and damage to the airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) Within 360 cycles in service after the 

effective date of this AD, remove the ball 

valve, P/N 2349M68P01, from the affected oil 

filler cap and replace with a part eligible for 

installation.
