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 Avenue SE., West Building Ground Floor, Room W12–140, Washington, DC 20590–0001.

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 PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 21161 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 https:// 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 E:\FR\FM\23APR1.SGM 23APR1 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. 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. mstockstill on DSKH9S0YB1PROD with RULES 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.

Series Turbojet Engines and CF700 Series Turbofan Engines

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.

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 hours-since-new (HSN) or 300 
cycles-since-new (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 https://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

[[Page 21162]]

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 work-hour. 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.
