AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting 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 

AD requires removing from service, AFT 

Technologies combustion liners, P/N 

AFT–5016T30G02. 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 issuing 

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: This AD becomes effective May 

28, 2010. 

ADDRESSES: The Docket Operations 

office is located at Docket Management 

Facility, U.S. Department of 

Transportation, 1200 New Jersey

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a proposed AD. The proposed AD 

applies to GE CJ610 series turbojet 

engines and CF700 turbofan engines 

with AFT Technologies combustion 

liners, P/N AFT–5016T30G02 installed. 

We published the proposed AD in the 

Federal Register on September 9, 2009 

(74 FR 46395). That action proposed to 

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, after the effective date 

of this AD, whichever occurs first, if the 

combustion liner has already exceeded 

200 HSN or 300 CSN. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comments received. 

Agrees With the Proposed AD 

One commenter agrees with the AD. 

Request To Replace ‘‘* * * Other 

Products of the Same Type Design’’ 

One commenter, AFT Technologies, 

asks us to replace ‘‘* * * other products 

of the same type design’’ with ‘‘* * * 

other products of the same 

manufacture.’’ The commenter feels 

‘‘The A.D. inadvertently suggests that 

despite PMA approval to manufacture 

the subject part, it’s failure or potential 

for failure is the result of a design 

defect, as opposed to an equally 

possible manufacturing or assembly 

defect.’’ And that the AD requires 

clarification. 

We do not agree that there is any need 

to distinguish between design and 

manufacture in the AD. The regulation 

that controls type design, 14 CFR part 

21.31, defines type design as design and 

manufacture. In addition, we didn’t 

make any conclusion as to the cause of 

the excessive cracking. Determination of 

the cracking is the responsibility of the 

PMA holder. As stated in the discussion 

of the proposed rule, ‘‘The PMA holder 

has not been able to determine the cause 

of the premature combustion liner 

failure.’’ Also, the statement ‘‘* * * 

other products of the same type design’’ 

appears only in the NPRM preamble 

section ‘‘FAA’s Determination and 

Requirements of the Proposed AD.’’ That 

mstockstill on DSKH9S0YB1PROD with RULES

21162 Federal Register / Vol. 75, No. 78 / Friday, April 23, 2010 / Rules and Regulations 

preamble section is not part of the final 

rule. We didn’t change the AD. 

Conclusion 

We have carefully reviewed the 

available data, including the 

comment[s] received, and determined 

that air safety and the public interest 

require adopting the AD as proposed. 

Costs of Compliance 

We estimate that this AD affects 13 

engines installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 96 work-hours per engine to 

perform the required actions, and that 

the average labor rate is $80 per workhour. Required parts will cost about 

$7,000 per engine. Based on these 

figures, we estimate the total cost of the 

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 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); and 

(3) 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. 

We prepared a summary of the costs 

to comply with this AD and placed it in 

the AD Docket. You may get a copy of 

this summary at the address listed 

under ADDRESSES.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the Federal Aviation Administration 

amends 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: 

2010–09–08 General Electric Company 

(GE): Amendment 39–16273. Docket No. 

FAA–2009–0502; Directorate Identifier 

2009–NE–02–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective May 28, 2010. 

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 issuing 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.
