[Docket No. FAA–2012–0817; Directorate 

Identifier 99–NE–24–AD]

Airworthiness Directives; General 

Electric Company Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to certain General Electric 

Company (GE) CF6–80C2 series 

turbofan engines. The existing AD 

requires replacement of the fuel tubes 

connected to the fuel flowmeter. Since 

we issued that AD, we received several 

additional reports of fuel leaks and two 

reports of engine fire due to misassembled supporting brackets on the 

fuel tube connecting the flowmeter to 

the Integrated Drive Generator (IDG) 

fuel-oil cooler. This proposed AD would 

require installing a new simplified onepiece bracket to eliminate mis-assembly. 

We are proposing this AD to prevent 

high-pressure fuel leaks caused by 

improper seating of fuel tube flanges, 

which could result in an engine fire and 

damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by October 12, 2012. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2012–0817; Directorate Identifier 

99–NE–24–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 

On February 17, 2000, we issued AD 

2000–04–14, Amendment 39–11597 (65 

FR 10698, February 29, 2000), for all GE 

CF6–80C2 series turbofan engines. That 

AD requires replacement of the fuel tube 

connecting the fuel flowmeter to the 

IDG fuel-oil cooler and the fuel tubes 

connecting the fuel flowmeter to the 

Main Engine Control (MEC) or 

Hydromechanical Unit (HMU) with 

improved fuel tubes. That AD resulted 

from reports of fuel leaking in the core 

cowl cavity under high pressure that 

can be ignited by contact with hot 

engine case surfaces. We issued that AD 

to prevent high-pressure fuel leaks 

caused by improper seating of fuel tube 

flanges, which could result in an engine 

fire and damage to the airplane. 

Actions Since Existing AD Was Issued 

Since we issued AD 2000–04–14, 

Amendment 39–11597 (65 FR 10698, 

February 29, 2000), we received several 

reports of fuel leaks and two reports of 

engine fire due to mis-assembled 

supporting brackets on the fuel tube 

connecting the fuel flowmeter to the 

IDG fuel-oil cooler. Investigation of 

these two fires determined the root 

cause was due to a design shortfall, 

which allowed improper installation of 

the two-piece bracket and subsequent 

fuel leaks from the fuel tube connection. 

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 

replacement of the fuel tube connecting 

the fuel flowmeter to the IDG fuel-oil 

cooler and the fuel tubes connecting the 

fuel flowmeter to the MEC or HMU with 

improved fuel tubes. This proposed AD 

would also require installing a 

simplified one-piece bracket to 

eliminate mis-assembly when the fuel 

tubes connecting the fuel flowmeter to 

the IDG fuel-oil cooler are disconnected. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 2,300 CF6–80C2 engines 

installed on airplanes of U.S. registry. 

We also estimate that one work-hour 

would be required per engine to 

accomplish the actions required by this 

AD. The average labor rate is $85 per 

work-hour. We also estimate that the 

required parts will cost about $180 per 

engine. Based on these figures, we 

estimate the total cost of the proposed 

AD to U.S. operators is $609,500. 

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, 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 77, No. 156 / Monday, August 13, 2012 / Proposed Rules 48111 

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 have 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 that the 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
