ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 777–200 series airplanes. This proposed AD would require installing a new insulation blanket on the latch beam firewall of each thrust reverser (T/R) half. This proposed AD results from an in-flight shutdown due to an engine fire indication; an undercowl engine fire was extinguished after landing. The cause of the fire was uncontained failure of the starter in the VerDate Nov<24>2008 16:34 May 06, 2009 Jkt 217001 engine core compartment; the fire progressed into the latch beam cavity and was fueled by oil from a damaged integrated drive generator oil line. We are proposing this AD to prevent a fire from entering the cowl or strut area, which could weaken T/R parts and result in reduced structural integrity of the T/R, possible separation of T/R parts during flight, and consequent damage to the airplane and injury to people or damage to property on the ground. DATES: We must receive comments on this proposed AD by June 22, 2009.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2009–0430; Directorate Identifier 2008–NM–148–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 https:// 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 have received a report of an inflight shutdown due to an engine fire indication; an under-cowl engine fire was extinguished after landing. The cause of the fire was uncontained failure of the starter in the engine core compartment; the fire progressed into the latch beam cavity and was fueled by oil from a damaged integrated drive generator oil line. The fire breached the bolt on the aluminum plate on the rear of the latch beam firewall and moved inside the translating sleeve. Installation of a thermal insulation blanket over the bolt on the aluminum plate area at the rear of the latch beam will protect that area of the firewall so it is not breached by fire. A fire entering the cowl or strut area could weaken thrust reverser (T/R) parts and result in reduced structural integrity of the T/R, possible separation of T/R parts during flight, and consequent damage to the airplane and injury to people or damage to property on the ground. Relevant Service Information We have reviewed Boeing Service Bulletin 777–78A0066, Revision 1, dated March 12, 2009. The service bulletin describes procedures for installing bonded studs and a new thermal insulation blanket with sealant on the latch beam firewall of each T/R half. E:\FR\FM\07MYP1.SGM 07MYP1 Federal Register / Vol. 74, No. 87 / Thursday, May 7, 2009 / Proposed Rules FAA’s Determination and Requirements of This Proposed AD We are proposing this AD because we evaluated all relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance We estimate that this proposed AD would affect 25 airplanes of U.S. registry. We also estimate that it would take about 7 work-hours per product to comply with this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost between $3,546 and $5,253 per product. Based on these figures, we estimate the cost of this proposed AD to the U.S. operators to be between $102,650 and 145,325, or between $4,106 and $5,813 per product. 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), and VerDate Nov<24>2008 16:34 May 06, 2009 Jkt 217001 21285 3.

Airworthiness Directives; Boeing Model 777-200 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Boeing Model 777-200 series airplanes. This proposed AD would 
require installing a new insulation blanket on the latch beam firewall 
of each thrust reverser (T/R) half. This proposed AD results from an 
in-flight shutdown due to an engine fire indication; an under-cowl 
engine fire was extinguished after landing. The cause of the fire was 
uncontained failure of the starter in the engine core compartment; the 
fire progressed into the latch beam cavity and was fueled by oil from a 
damaged integrated drive generator oil line. We are proposing this AD 
to prevent a fire from entering the cowl or strut area, which could 
weaken T/R parts and result in reduced structural integrity of the T/R, 
possible separation of T/R parts during flight, and consequent damage 
to the airplane and injury to people or damage to property on the 
ground.

DATES: We must receive comments on this proposed AD by June 22, 2009.

listed under the ADDRESSES section. Include ``Docket No. FAA-2009-0430; 
Directorate Identifier 2008-NM-148-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.

Discussion

    We have received a report of an in-flight shutdown due to an engine 
fire indication; an under-cowl engine fire was extinguished after 
landing. The cause of the fire was uncontained failure of the starter 
in the engine core compartment; the fire progressed into the latch beam 
cavity and was fueled by oil from a damaged integrated drive generator 
oil line. The fire breached the bolt on the aluminum plate on the rear 
of the latch beam firewall and moved inside the translating sleeve. 
Installation of a thermal insulation blanket over the bolt on the 
aluminum plate area at the rear of the latch beam will protect that 
area of the firewall so it is not breached by fire. A fire entering the 
cowl or strut area could weaken thrust reverser (T/R) parts and result 
in reduced structural integrity of the T/R, possible separation of T/R 
parts during flight, and consequent damage to the airplane and injury 
to people or damage to property on the ground.

Relevant Service Information

    We have reviewed Boeing Service Bulletin 777-78A0066, Revision 1, 
dated March 12, 2009. The service bulletin describes procedures for 
installing bonded studs and a new thermal insulation blanket with 
sealant on the latch beam firewall of each T/R half.

FAA's Determination and Requirements of This Proposed AD

    We are proposing this AD because we evaluated all relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design. 
This proposed AD would require accomplishing the actions specified in 
the service information described previously.

Costs of Compliance

    We estimate that this proposed AD would affect 25 airplanes of U.S. 
registry. We also estimate that it would take about 7 work-hours per 
product to comply with this proposed AD. The average labor rate is $80 
per work-hour. Required parts would cost between $3,546 and $5,253 per 
product. Based on these figures, we estimate the cost of this proposed 
AD to the U.S. operators to be between $102,650 and 145,325, or between 
$4,106 and $5,813 per product.

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), 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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.
