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) model 

GEnx-2B67 and GEnx-2B67B turbofan 

engines with booster anti-ice (BAI) air 

duct, part number (P/N) 2469M32G01, 

and support bracket, P/N 2469M46G01, 

installed. This proposed AD was 

prompted by reports of cracks in the 

BAI air duct. This proposed AD would 

require initial and repetitive visual 

inspections of the BAI air duct, removal 

from service of the BAI air duct if it fails 

inspection and, as a mandatory 

terminating action, the installation of 

new BAI air duct support brackets. We 

are proposing this AD to prevent failure 

of the BAI air duct, resulting in an inflight shutdown of one or more engines, 

loss of thrust control, and damage to the 

aircraft. 

DATES: We must receive comments on 

this proposed AD by June 10, 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– 

2013–0195; Directorate Identifier 2013– 

NE–08–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 all 

GE model GEnx-2B67 and GEnx-2B67B 

turbofan engines with BAI air duct, 

P/N 2469M32G01, and support bracket, 

P/N 2469M46G01, installed. This 

proposed AD was prompted by 11 

reports of cracks in the BAI air duct, 

P/N 2469M32G01, caused by resonant 

vibration of the BAI valve system. 

Engineering analysis determined that 

the single support bracket is not 

sufficient to prevent the vibration and 

cracking in the BAI air duct, and that 

additional support brackets are needed. 

This proposed AD would require initial 

visual inspection of the BAI air duct 

before it reaches 400 cycles since new 

(CSN), and repetitive visual inspections 

every 100 cycles thereafter. If the BAI 

air duct fails inspection, the proposed 

AD would require removal of the BAI 

air duct from service. As a mandatory 

terminating action, the proposed AD 

would also require installation of new 

BAI air duct support brackets at the next 

removal of the BAI air duct, and 

replacement of the BAI air duct with a 

duct eligible for installation. This 

condition, if not corrected, could result 

in failure of the BAI air duct, resulting 

in an in-flight shutdown of one or more 

engines, loss of thrust control, and 

damage to the aircraft. 

Relevant Service Information 

We reviewed GE Service Bulletin (SB) 

No. GEnx-2B S/B 75–0006, dated July 

23, 2012, and GE SB No. GEnx-2B S/B 

75–0008, Revision 1, dated February 4, 

2013. GE SB No. GEnx-2B S/B 75–0006 

describes procedures for inspecting and, 

if necessary, removing and replacing the 

BAI air duct. GE SB No. GEnx-2B S/B 

75–0008, Revision 1, describes 

procedures for installing new BAI air 

duct support brackets, and inspection 

and possible replacement of BAI air 

ducts. 

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 

initial and repetitive visual inspections 

of the BAI air duct, replacement of the 

BAI air duct if it fails inspection and, as 

mandatory terminating action, 

installation of new BAI air duct support 

brackets. 

Costs of Compliance 

We estimate that this proposed AD 

affects 16 engines installed on airplanes 

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

would take about 4 hours per engine to 

comply with this proposed AD. The 

average labor rate is $85 per hour. 

Required parts would cost about 

$11,000 per engine. Based on these 

figures, we estimate the cost of the 

proposed AD to U.S. operators to be 

$181,440. 

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 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska to the extent that it justifies 

making a regulatory distinction, 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.
