Airworthiness Directives; General 

Electric Company Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

General Electric Company (GE) GE90– 

110B1 and GE90–115B turbofan 

engines. This emergency AD was sent 

previously to all known U.S. owners 

and operators of these engines. This AD 

prohibits operation of an airplane with 

affected transfer gearbox assemblies 

(TGBs) installed on both engines five 

days after the effective date of this AD. 

This AD was prompted by reports of 

two failures of TGBs which resulted in 

in-flight shutdowns (IFSDs). We are 

issuing this AD to prevent additional 

IFSDs of one or more engines, loss of 

thrust control, and damage to the 

airplane. 

DATES: This AD is effective June 26, 

2013 to all persons except those persons 

to whom it was made immediately 

effective by Emergency AD 2013–10–52, 

issued on May 16, 2013, which 

contained the requirements of this 

amendment. 

We must receive comments on this 

AD by August 12, 2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

SUPPLEMENTARY INFORMATION:

Discussion 

On May 16, 2013, we issued 

Emergency AD 2013–10–52, which 

prohibits operation of an airplane with 

affected TGBs installed on both engines 

five days after receipt of the emergency 

AD. The emergency AD was sent 

previously to all known U.S. owners 

and operators of these GE90–110B1 and 

GE90–115B turbofan engines. This 

action was prompted by reports of two 

failures of TGBs which resulted in 

IFSDs. Investigation has revealed that 

the failures were caused by TGB radial 

gear cracking and separation. Further 

inspections found two additional radial 

gears with cracks. This condition, if not 

corrected, could result in additional 

IFSDs of one or more engines, loss of 

thrust control, and damage to the 

airplane. 

Relevant Service Information 

We reviewed GE GE90–100 Series 

Alert Service Bulletin (ASB) No. GE90– 

100 S/B 72–A0558, Revision 1, dated 

May 14, 2013, and GE90–100 Series 

ASB No. GE90–100 S/B 72–A0559, 

dated May 14, 2013. The ASBs provide 

additional information regarding the 

affected TGBs. 

FAA’s Determination 

We are issuing 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. 

AD Requirements 

This AD prohibits operation of an 

airplane with affected TGBs installed on 

both engines five days after the effective 

date of this AD. 

Interim Action 

We consider this AD to be an interim 

action. We anticipate that further AD 

action will follow. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because of the five-day compliance 

time. Therefore, we find that notice and 

opportunity for prior public comment 

are impracticable and that good cause 

exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include the docket number 

FAA–2013–0447 and Directorate 

Identifier 2013–NE–17–AD at the 

beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

mstockstill on DSK4VPTVN1PROD with RULES

38196 Federal Register / Vol. 78, No. 123 / Wednesday, June 26, 2013 / Rules and Regulations 

received by the closing date and may 

amend this 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 AD. 

Costs of Compliance 

We estimate that this AD affects 20 

engines installed on airplanes of U.S. 

registry, and because the compliance is 

only an airplane operation prohibition, 

the cost of compliance on U.S. operators 

is $0. 

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 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.

SUPPLEMENTARY INFORMATION: 

History 

On April 29, 2013, the FAA published 

in the Federal Register a notice of 

proposed rulemaking (NPRM) to 

establish controlled airspace at Port 

Townsend, WA (78 FR 25005). 

Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received. 

Class E airspace designations are 

published in paragraph 6005, of FAA 

Order 7400.9W dated August 8, 2012, 

and effective September 15, 2012, which 

is incorporated by reference in 14 CFR 

71.1. The Class E airspace designations 

listed in this document will be 

published subsequently in that Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

establishing Class E airspace extending 

upward from 700 feet above the surface 

within a 9.3-mile radius of Jefferson 

County International Airport, with a 

segment extending from the radius of 

the airport to 10.1 miles west of the 

airport, and from 1,200 feet above the 

surface within stated geographic 

coordinates of the airport, to 

accommodate IFR aircraft executing 

new RNAV (GPS) standard instrument 

approach procedures. This action is 

necessary for the safety and 

management of IFR operations. 

The FAA has determined this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (1) Is 

not a ‘‘significant regulatory action’’ 

under Executive Order 12866; (2) is not 

mstockstill on DSK4VPTVN1PROD with RULES
