ACTION: Final rule; request for comments. AGENCY: SUMMARY: This document publishes in the Federal Register an amendment adopting emergency airworthiness directive (AD) 2005–09–51 that we sent previously to all known U.S. owners and operators of certain Turbomeca Arrius 2F turboshaft engines. This AD requires before further flight, replacing the Module 2 on certain engines listed by serial number (SN) in this AD. This AD results from a report of the failure of a high pressure turbine (HPT) blade and damage to two other HPT blades in a Turbomeca Arrius 2F turboshaft engine. We are issuing this AD to prevent failure of the engine and subsequent loss of power. DATES: This AD becomes effective June 3, 2005 to all persons except those persons to whom it was made immediately effective by emergency AD 2005–09–51, issued on April 28, 2005, which contained the requirements of this amendment. We must receive any comments on this AD by July 18, 2005.

The Direction General De L’Aviation Civile (DGAC), which is the airworthiness authority for France, recently notified us that an unsafe condition might exist on certain Turbomeca Arrius 2F turboshaft engines. The DGAC advises that on March 31, 2005, the failure of an HPT blade and damage to two other HPT blades in a Turbomeca Arrius 2F turboshaft engine caused an in-flight engine shutdown (IFSD). That IFSD resulted in loss of the helicopter and fatalities and injuries to the occupants. A preliminary investigation of the engine found that a ferrule started a disturbance that reduced the cooling effect of the secondary air system. The secondary air system cools the HPT. Turbomeca identified 38 engines that might contain a configuration similar to the engine involved in the accident. This condition, if not corrected, could result in failure of the engine and subsequent loss of power. On April 28, 2005, we issued emergency AD 2005– 09–51 that applies to certain Turbomeca Arrius 2F turboshaft engines. That AD requires before further flight, replacing the Module 2 on certain engines listed by SN in that AD. SUPPLEMENTARY INFORMATION: Bilateral Airworthiness Agreement This Turbomeca Arrius 2F turboshaft engine model is manufactured in France and is type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Under this bilateral airworthiness agreement, the DGAC kept the FAA informed of the situation described above. We have examined the findings of the DGAC, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States. E:\FR\FM\19MYR1.SGM 19MYR1 28792 Federal Register / Vol. 70, No. 96 / Thursday, May 19, 2005 / Rules and Regulations FAA’s Determination and Requirements of This AD 2000 (65 FR 19477–78) or you may visit https://dms.dot.gov. this summary at the address listed under ADDRESSES. Since the unsafe condition described is likely to exist or develop on other engines of the same type design, we issued emergency AD 2005–09–51 to prevent failure of the engine and subsequent loss of power. This AD requires before further flight, replacing the Module 2, on certain engines listed by SN in this AD. Examining the AD Docket List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. FAA’s Determination of the Effective Date Since an unsafe condition exists that requires the immediate adoption of this AD, we have found that notice and opportunity for public comment before issuing this AD are impracticable, and that good cause existed to make the AD effective immediately on April 28, 2005, to all known U.S. owners and operators of Turbomeca Arrius 2F turbofan engines. These conditions still exist, and we are publishing the AD in the Federal Register as an amendment to Section 39.13 of part 39 of the Code Federal Regulations (14 CFR part 39) to make it effective to all persons. Interim Action These actions are interim actions and we may take further rulemaking actions in the future. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment.

That action, published in the Federal Register on January 5, 2005 (70 FR 735), proposed to require replacing the pressure switches on the override/jettison fuel pumps with new pressure switches, and replacing the ship side electrical connectors for the pressure switches on override/jettison fuel pumps with new connectors. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments that have been submitted on the proposed AD. One commenter concurs with the contents of the proposed AD. Request To Clarify Applicability One commenter states that there is a concern for possible misinterpretation of the applicability specified in the Summary and Applicability sections of the proposed AD. The commenter adds that the referenced service bulletin specifically identifies the affected airplanes, and it is only applicable to Boeing Model 777–200 series airplanes equipped with no center wing tank, and is not applicable to Boeing Model 777– 200ER series airplanes. The commenter recommends clarification that Model 777–200ER series airplanes are not affected be added to the proposed AD. We acknowledge the commenter’s concern and offer clarification. The proposed AD is applicable to Boeing Model 777–200 series airplanes, certificated in any category; as identified in Boeing Special Attention Service Bulletin 777–28–0036, dated September 2, 2004. There are two center wing tank configurations certificated on the Model 777–200 series airplane; the referenced service bulletin identifies the airplanes that have the smaller tank configuration. The other Model 777–200 series airplanes, informally referred to by Boeing as Model 777–200ER airplanes, have a larger center wing tank and a different pump inlet configuration. Therefore, Model 777– 200ER airplanes are not subject to the identified unsafe condition. We have not changed the final rule in this regard. Request To Change the Costs of Compliance Section/Compliance Time One commenter asks that the work hours shown in the estimated costs table in the proposed AD be reconsidered.

SUPPLEMENTARY INFORMATION: The Direction General De L'Aviation Civile 
(DGAC), which is the airworthiness authority for France, recently 
notified us that an unsafe condition might exist on certain Turbomeca 
Arrius 2F turboshaft engines. The DGAC advises that on March 31, 2005, 
the failure of an HPT blade and damage to two other HPT blades in a 
Turbomeca Arrius 2F turboshaft engine caused an in-flight engine 
shutdown (IFSD). That IFSD resulted in loss of the helicopter and 
fatalities and injuries to the occupants. A preliminary investigation 
of the engine found that a ferrule started a disturbance that reduced 
the cooling effect of the secondary air system. The secondary air 
system cools the HPT. Turbomeca identified 38 engines that might 
contain a configuration similar to the engine involved in the accident. 
This condition, if not corrected, could result in failure of the engine 
and subsequent loss of power. On April 28, 2005, we issued emergency AD 
2005-09-51 that applies to certain Turbomeca Arrius 2F turboshaft 
engines. That AD requires before further flight, replacing the Module 2 
on certain engines listed by SN in that AD.

Bilateral Airworthiness Agreement

    This Turbomeca Arrius 2F turboshaft engine model is manufactured in 
France and is type certificated for operation in the United States 
under the provisions of section 21.29 of the Federal Aviation 
Regulations (14 CFR 21.29) and the applicable bilateral airworthiness 
agreement. Under this bilateral airworthiness agreement, the DGAC kept 
the FAA informed of the situation described above. We have examined the 
findings of the DGAC, reviewed all available information, and 
determined that AD action is necessary for products of this type design 
that are certificated for operation in the United States.

[[Page 28792]]

FAA's Determination and Requirements of This AD

    Since the unsafe condition described is likely to exist or develop 
on other engines of the same type design, we issued emergency AD 2005-
09-51 to prevent failure of the engine and subsequent loss of power. 
This AD requires before further flight, replacing the Module 2, on 
certain engines listed by SN in this AD.

FAA's Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we have found that notice and opportunity for 
public comment before issuing this AD are impracticable, and that good 
cause existed to make the AD effective immediately on April 28, 2005, 
to all known U.S. owners and operators of Turbomeca Arrius 2F turbofan 
engines. These conditions still exist, and we are publishing the AD in 
the Federal Register as an amendment to Section 39.13 of part 39 of the 
Code Federal Regulations (14 CFR part 39) to make it effective to all 
persons.

Interim Action

    These actions are interim actions and we may take further 
rulemaking actions in the future.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send us any written relevant data, 
views, or arguments regarding this AD. Send your comments to an address 
listed under ADDRESSES. Include ``AD Docket No. FAA-2005-21155; 
Directorate Identifier 2005-NE-14-AD'' in the subject line of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify it.
    We will post all comments we receive, without change, to https://
dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact with FAA 
personnel concerning this AD. Using the search function of the DMS web 
site, anyone can find and read the comments in any of our dockets, 
including the name of the individual who sent the comment (or signed 
the comment on behalf of an association, business, labor union, etc.). 
You may review the DOT's complete Privacy Act Statement in the Federal 
Register published on April 11, 2000 (65 FR 19477-78) or you may visit

Examining the AD Docket

    You may examine the docket that contains the AD, any comments 
received, and any final disposition in person at the DMS Docket Offices 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Office (telephone (800) 647-5227) is located on 
the plaza level of the Department of Transportation Nassif Building at 
the street address stated in ADDRESSES. Comments will be available in 
the AD docket shortly after the DMS receives them.

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 the 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.
    We prepared a summary of the costs to comply with this AD and
