Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 


emcdonald on DSK67QTVN1PROD with PROPOSALS
47236 Federal Register / Vol. 78, No. 150 / Monday, August 5, 2013 / Proposed Rules 

General Electric Company (GE) model 

GEnx–2B67 and GEnx–2B67B turbofan 

engines. This proposed AD was 

prompted by the original equipment 

manufacturer’s disclosure that certain 

critical rotating life-limited parts (LLPs) 

used in Boeing 747–8 flight tests had 

consumed more cyclic life than they 

would have in revenue flight cycles. 

These parts were then installed into 

engines and introduced into revenue 

service without adjustment to remaining 

cyclic life. This proposed AD would 

require a one-time adjustment to the 

cycle counts of those LLPs to account 

for the additional low cycle fatigue 

(LCF) life consumed during flight tests. 

We are proposing this AD to prevent the 

failure of critical rotating LLPs, 

uncontained engine failure, and damage 

to the airplane. 

DATES: We must receive comments on 

this proposed AD by October 4, 2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

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– 

2013–0475; Directorate Identifier 13– 

NE–18–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed 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 proposed AD. 

Discussion 

We propose to adopt a new AD for 

certain GE model GEnx–2B67 and 

GEnx–2B67B turbofan engines. This 

proposed AD was prompted by GE’s 

disclosure that certain critical rotating 

LLPs used in Boeing 747–8 flight tests 

had consumed more cyclic life than 

they would have in revenue flight 

cycles. This additional life usage was 

due to multiple changes in the engine 

rotor speed and thermal environment 

that are not performed in a typical 

revenue service flight. These parts were 

then installed into engines and 

introduced into revenue service without 

adjustment to remaining cyclic life. This 

proposed AD would require a one-time 

adjustment to the cycle counts of those 

LLPs to account for the additional LCF 

life consumed. This condition, if not 

corrected, could result in the failure of 

critical rotating LLPs, uncontained 

engine failure, and damage to the 

airplane. 

Relevant Service Information 

We reviewed GE Service Bulletin (SB) 

No. 72–0116, Revision 1, dated April 23, 

2013. The SB lists each affected critical 

rotating LLP by part number and serial 

number and prescribes the exact 

number of cycles to add to the cycle 

count for each affected LLP as a onetime adjustment. The list is extensive. 

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 these same 

type designs. 

Proposed AD Requirements 

This proposed AD would require a 

one-time adjustment to the cycle counts 

of certain critical rotating LLPs. 

Costs of Compliance 

We estimate that this proposed AD 

affects 4 engines installed on airplanes 

of U.S. registry. We also estimate that it 

would take about 1 hour per engine to 

comply with this proposed AD. The 

average labor rate is $85 per hour. The 

prorated cost of required parts would be 

about $50,000 per engine. Based on 

these figures, we estimate the cost of the 

proposed AD to U.S. operators to be 

$200,340. 

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 

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

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

General Electric Company: Docket No. FAA– 

2013–0475; Directorate Identifier 2013– 

NE–18–AD. 

(a) Comments Due Date 

We must receive comments by October 4, 

2013. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to certain serial number 

General Electric Company (GE) model GEnx– 

2B67 and GEnx–2B67B turbofan engines. The 

affected GEnx–2B serial numbers are: 959– 

102 through 959–104; 959–107; 959–110 

through 959–111; 959–113 through 959–118; 

959–121; 959–124 through 959–133; 959–159 

through 959–161; 959–164; 959–176; and
