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– 

80E1 turbofan engines with rotating 

compressor discharge pressure (CDP) 

seal, part number (P/N) 1669M73P02, 

installed. This proposed AD was 

prompted by reports from the 

manufacturer of cracks in the teeth of 

two rotating CDP seals found during 

engine shop visits. This proposed AD 

would require stripping of the coating, 

inspecting, and recoating the teeth of 

the affected rotating CDP seals. We are 

proposing this AD to prevent cracking of 

the CDP seal teeth, which can lead to 

uncontained part release, damage to the 

engine, and damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by January 19, 2016. 

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 proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2015–4023; Directorate Identifier 2015– 

NE–29–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 received reports from GE of cracks 

in the teeth on two rotating CDP seals 

found during engine shop visits. We 

learned that the current borazon-nickel 

seal tooth coating oxidizes during 

engine operation, which could lead to 

reduced cutting action, overheating of 

the seal teeth, and premature cracking of 

the seal teeth. This condition, if not 

corrected, could result in cracking of the 

CDP seal teeth, uncontained part 

release, damage to the engine, and 

damage to the airplane. 

Relevant Service Information Under 1 

CFR Part 51 

We reviewed GE Service Bulletin (SB) 

No. CF6–80E1 S/B 72–0529, Revision 1, 

dated August 21, 2015. The SB 

describes procedures for stripping, 

inspecting, and replacing the seal tooth 

coating on the affected rotating CDP 

seals. This service information is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section of this document. 

Other Related Service Information 

We reviewed GE CF6–80E1 

(GEK99376) Engine Manual, Revision 

42, dated March 15, 2014. The engine 

manual describes acceptable repair 

procedures for the seal teeth. 

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 

stripping, inspecting, and recoating the 

teeth on the affected CDP seals. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 6 engines installed on 

airplanes of U.S. registry. We also 

estimate that it will take about 7 hours 

per engine to comply with this proposed 

AD. The average labor rate is $85 per 

hour. Parts would cost about $7,835 per 

engine. Based on these figures, we 

estimate the total cost of this proposed 

AD to U.S. operators to be $50,657. 

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. 

List of Subjects in 14 CFR Part 39
