Federal Aviation Administration 

14 CFR Part 39 

[Docket No. FAA–2009–0502; Directorate 

Identifier 2009–NE–02–AD] 

RIN 2120–AA64 

Airworthiness Directives; General 

Electric Company (GE) CJ610 Series 

Turbojet Engines and CF700 Series 

Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for GE 

CJ610 series turbojet engines and CF700 

turbofan engines with AFT 

Technologies combustion liners, part 

number (P/N) AFT–5016T30G02. This 

proposed AD would require removing 

from service, AFT Technologies 

combustion liners, P/N AFT– 

5016T30G02. This proposed AD results 

from a report of an AFT Technologies 

combustion liner that released a large 

section of the inner combustion liner 

and reports of six combustion liners 

with premature cracks. We are 

proposing this AD to prevent premature 

cracks in the combustion liner, which 

could release pieces of the inner 

combustion liner. A release of pieces of 

the inner combustion liner could cause 

an uncontained failure of the engine 

turbine and damage to the airplane. 

DATES: We must receive any comments 

on this proposed AD by November 9, 

2009.

addresses to comment on this proposed 

AD.

Discussion 

We have received a report of a large 

section of a combustion liner breaking 

free that caused damage to the turbine 

and excessive engine vibration. Also, we 

have received six reports of premature 

combustion liner cracking, determined 

by borescope inspection and 

precautionary removal of the 

combustion liners by the repair facility. 

Excessive cracking of the combustion 

liner could result in liberation of 

combustion liner pieces and damage to 

the turbine. The PMA holder has not 

been able to determine the cause of the 

premature combustion liner failure. 

Without a prohibition against installing 

a new or serviceable AFT Technologies 

combustion liner in the field and at 

AFT, there will be nothing to prevent a 

large piece of the combustion liner from 

releasing and damaging the turbine. 

This condition, if not corrected, could 

result in an uncontained failure of the 

engine turbine and damage to the 

airplane. 

FAA’s Determination and Requirements 

of the Proposed AD 

We have evaluated all pertinent 

information and identified an unsafe 

condition that is likely to exist or 

develop on other products of this same 

type design. We are proposing this AD, 

which would require replacing 

combustion liners, P/N AFT– 

5016T30G02: 

• Before they accumulate 200 hourssince-new (HSN) or 300 cycles-sincenew (CSN), or 

• Within 15 hours-in-service or 10 

cycles-in-service if the combustion liner 

has already exceeded 200 HSN or 300 

CSN. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 13 engines installed on 

airplanes of U.S. registry. We also 

estimate that it would take about 96 

work-hours per engine to perform the 

proposed actions, and that the average 

labor rate is $80 per work-hour. 

Required parts would cost about $7,000 

per engine. Based on these figures, we 


jlentini on DSKJ8SOYB1PROD with PROPOSALS
46396 Federal Register / Vol. 74, No. 173 / Wednesday, September 9, 2009 / Proposed Rules 

estimate the total cost of the proposed 

AD to U.S. operators to be $190,840. 

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 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 AD: 

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); and 

3. Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD. You may get a copy 

of this summary at the address listed 

under ADDRESSES. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

The Proposed Amendment 

Under the authority delegated to me 

by the Administrator, the Federal 

Aviation Administration proposes to 

amend 14 CFR part 39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

General Electric Company (GE): Docket No. 

FAA–2009–0502; Directorate Identifier 

2009–NE–02–AD. 

Comments Due Date 

(a) The Federal Aviation Administration 

(FAA) must receive comments on this 

airworthiness directive (AD) action by 

November 9, 2009. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to GE CJ610 series 

turbojet and CF700 series turbofan engines 

with AFT Technologies combustion liner, 

part number (P/N) AFT–5016T30G02, 

installed. These engines are installed on, but 

not limited to, Learjet Inc. model 24 series 

and model 25 series airplanes, Dassault 

Aviation Fan Jet Falcon series airplanes, and 

Sabreliner Corporation NA–265–70 and NA– 

265–80 series airplanes. 

Unsafe Condition 

(d) This AD results from a report of an AFT 

Technologies combustion liner that released 

a large section of the inner combustion liner 

and reports of six combustion liners with 

premature cracks. We are proposing this AD 

to prevent premature cracks in the 

combustion liner, which could release pieces 

of the inner combustion liner. A release of 

pieces of the inner combustion liner could 

cause an uncontained failure of the engine 

turbine and damage to the airplane. 

Compliance 

(e) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified unless the 

actions have already been done. 

Replacement of AFT Technologies 

Combustion Liner P/N AFT–5016T30G02 

(f) For engines that have an AFT 

Technologies combustion liner, P/N AFT– 

5016T30G02, with fewer than 200 hourssince-new (HSN) or 300 cycles-since-new 

(CSN), remove the AFT Technologies 

combustion liner, P/N AFT–5016T30G02, 

before exceeding 200 HSN or 300 CSN, 

whichever occurs first. 

(g) For engines that have an AFT 

Technologies combustion liner, P/N AFT– 

5016T30G02, with 200 HSN or more or 300 

CSN or more, remove the AFT Technologies 

combustion liner, P/N AFT–5016T30G02, 

within 15 hours-in-service or 10 cycles-inservice, after the effective date of this AD, 

whichever occurs first. 

(h) After the effective date of this AD, don’t 

install any AFT Technologies combustion 

liner, P/N AFT–5016T30G02, in any engine. 

Alternative Methods of Compliance 

(i) The Manager, New York Aircraft 

Certification Office, has the authority to 

approve alternative methods of compliance 

for this AD if requested using the procedures 

found in 14 CFR 39.19.
