AGENCY: E:\FR\FM\24JNR1.SGM 24JNR1 Federal Register / Vol. 70, No. 121 / Friday, June 24, 2005 / Rules and Regulations Final rule; request for comments. ACTION: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for Turbomeca S.A. Arriel 2B turboshaft engines with Modification TU62A incorporated. This AD results from several reports of the hydromechanical unit (HMU) acceleration controller axle sticking. This AD requires initial and repetitive inspections, cleaning, lubrication, and checks for proper operation of the HMU acceleration controller axle. We are issuing this AD to prevent loss of control of engine fuel flow in manual control mode or mixed control mode, leading to engine overspeed and in-flight engine shutdown, or uncommanded in-flight engine shutdown. DATES: Effective July 11, 2005. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of July 11, 2005. We must receive any comments on this AD by August 23, 2005.

SUPPLEMENTARY INFORMATION: The Direction Generale de L’Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition might exist on Turbomeca S.A. Arriel 2B turboshaft engines with Modification TU62A incorporated. The DGAC advises that VerDate jul<14>2003 16:42 Jun 23, 2005 Jkt 205001 several reports of the HMU acceleration controller axle sticking have been received that resulted in engine overspeed and in-flight engine shutdown, or uncommanded in-flight engine shutdown. These events can occur when the fuel system is either in manual control mode or mixed control mode. They are most likely to occur during an HMU failure simulation or during autorotation training. HMU acceleration controller axle sticking can result in an excessive decrease in engine speed when the manual control is used to reduce fuel flow. It can also result in an excessive increase in engine speed when moving the control back to the flight notch. We are issuing this AD to prevent loss of control of engine fuel flow in the manual control mode or mixed control mode, leading to engine overspeed and in-flight engine shutdown, or uncommanded in-flight engine shutdown. Relevant Service Information We have reviewed and approved the technical contents of Turbomeca Alert Mandatory Service Bulletin (ASB) No. A292 73 2814, Update No. 1, dated January 11, 2005. That ASB describes procedures for inspecting, lubricating, and checking for proper operation of the HMU acceleration controller axle. The DGAC classified this service bulletin as mandatory and issued AD F–2004–139, dated August 18, 2004, in order to ensure the airworthiness of these Arriel 2B turboshaft engines in France. Bilateral Airworthiness Agreement This Turbomeca Arriel 2B turboshaft engine model is manufactured in France. It 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 has 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. FAA’s Determination and Requirements of This AD The unsafe condition described previously is likely to exist or develop on other Turbomeca Arriel 2B turboshaft engines of the same type design. We are issuing this AD to prevent loss of control of engine fuel flow in the manual control mode or mixed control mode, leading to engine PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 36481 overspeed and in-flight engine shutdown, or uncommanded in-flight engine shutdown. This AD requires initial and repetitive inspections, cleaning, lubrication, and checks for proper operation of the HMU acceleration controller axle. You must use the service information described previously to perform the actions required by this AD. 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. We also found that good cause exists for making this amendment effective in less than 30 days. 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.

SUPPLEMENTARY INFORMATION: The Direction Generale de L'Aviation Civile 
(DGAC), which is the airworthiness authority for France, notified us 
that an unsafe condition might exist on Turbomeca S.A. Arriel 2B 
turboshaft engines with Modification TU62A incorporated. The DGAC 
advises that several reports of the HMU acceleration controller axle 
sticking have been received that resulted in engine overspeed and in-
flight engine shutdown, or uncommanded in-flight engine shutdown. These 
events can occur when the fuel system is either in manual control mode 
or mixed control mode. They are most likely to occur during an HMU 
failure simulation or during autorotation training. HMU acceleration 
controller axle sticking can result in an excessive decrease in engine 
speed when the manual control is used to reduce fuel flow. It can also 
result in an excessive increase in engine speed when moving the control 
back to the flight notch. We are issuing this AD to prevent loss of 
control of engine fuel flow in the manual control mode or mixed control 
mode, leading to engine overspeed and in-flight engine shutdown, or 
uncommanded in-flight engine shutdown.

Relevant Service Information

    We have reviewed and approved the technical contents of Turbomeca 
Alert Mandatory Service Bulletin (ASB) No. A292 73 2814, Update No. 1, 
dated January 11, 2005. That ASB describes procedures for inspecting, 
lubricating, and checking for proper operation of the HMU acceleration 
controller axle. The DGAC classified this service bulletin as mandatory 
and issued AD F-2004-139, dated August 18, 2004, in order to ensure the 
airworthiness of these Arriel 2B turboshaft engines in France.

Bilateral Airworthiness Agreement

    This Turbomeca Arriel 2B turboshaft engine model is manufactured in 
France. It 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 has 
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.

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other Turbomeca Arriel 2B turboshaft engines of the same 
type design. We are issuing this AD to prevent loss of control of 
engine fuel flow in the manual control mode or mixed control mode, 
leading to engine overspeed and in-flight engine shutdown, or 
uncommanded in-flight engine shutdown. This AD requires initial and 
repetitive inspections, cleaning, lubrication, and checks for proper 
operation of the HMU acceleration controller axle. You must use the 
service information described previously to perform the actions 
required by this AD.
    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. We also found 
that good cause exists for making this amendment effective in less than 
30 days.

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-2005-21624; 
Directorate Identifier 2005-NE-17-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

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 
placed it in the AD Docket. You may get a copy of this summary by 
sending a request to us at the address listed under ADDRESSES.
