Identifier 2015–NE–32–AD] 

RIN 2120–AA64 

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) CF6– 

80C2 and CF6–80E1 turbofan engines. 

This proposed AD was prompted by 

reports of a burn-through of the 

accessory heat shield during an 

accessory compartment fire leading to 

an engine fire. This proposed AD would 

require replacing the accessory heat 

shield assembly. We are proposing this 

AD to prevent high-temperature gas 

ingestion into the accessory 

compartment, engine fire, and damage 

to the airplane. 

DATES: We must receive comments on 

this proposed AD by February 5, 2016. 

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 NPRM. Send your comments to an 

address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2015–4344; Directorate Identifier 2015– 

NE–32–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this NPRM. We will consider 

all comments received by the closing 

date and may amend this NPRM 

because of those comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any

will also post a report summarizing each 

substantive verbal contact we receive 

about this NPRM. 

Discussion 

We received reports of a burn-through 

of the accessory heat shield during an 

engine fire leading to an accessory 

compartment fire. A fire burns through 

the accessory heat shield and ignites the 

integrated drive generator (IDG), which 

supports further combustion. The 

existing accessory heat shield assembly 

leaves a large area above the sensitive 

accessories, such as the IDG and the 

main fuel pump, without adequate 

protection. A total of five events have 

occurred. This condition, if not 

corrected, could result in hightemperature gas ingestion into the 

accessory compartment, which could 

lead to engine fire and damage to the 

airplane. 

Related Service Information Under 1 

CFR Part 51 

We reviewed GE Service Bulletin (SB) 

No. CF6–80C2 S/B 72–1520, dated 

September 22, 2015 and GE SB No. 

CF6–80E1 S/B 72–0525, dated 

September 22, 2015. These SBs describe 

the procedures for removing and 

replacing the accessory heat shield 

assembly. This service information is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 

or see ADDRESSES for other ways to 

access this service information. 

Other Related Service Information 

We reviewed GE SB No. CF6–80C2 S/ 

B 72–1523, dated September 22, 2015. 

The SB describes procedures for 

removing and replacing the accessory 

heat shield assembly. 

FAA’s Determination 

We are proposing this NPRM 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 NPRM would require replacing 

the accessory heat shield assembly. 

Costs of Compliance 

We estimate that this proposed AD 

affects 935 engines installed on 

airplanes of U.S. registry. We also 

estimate that it would take about 5 

hours per engine to comply with this 

proposed AD. The average labor rate is 

$85 per hour. Parts would cost about 

$1,832 per engine. Based on these 

figures, we estimate the total cost of this

Federal Register / Vol. 80, No. 234 / Monday, December 7, 2015 / Proposed Rules 75953 

proposed AD to U.S. operators to be 

$2,110,295. 

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.
