ACTION: Final rule; request for comments. SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for Turbomeca Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines. That AD currently requires initial and repetitive visual inspections of certain reduction gearboxes (module M05) for oil leakage, repair if leaking, and repair of all affected modules as optional terminating action to the repetitive inspections. This AD requires the same actions, but adds five more serial numbers of the reduction gearboxes (module M05) that are affected, and adds an alternative optional terminating action to the repetitive visual inspections. This AD results from Turbomeca identifying five additional reduction gearboxes (module M05) affected, and adding an alternative optional terminating action to the repetitive visual inspections. We are issuing this AD to prevent uncommanded in-flight engine shutdown, possible engine fire, and an emergency autorotation landing. DATES: Effective January 12, 2010, the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of January 12, 2010. We must receive any comments on this AD by February 26, 2010.

SUPPLEMENTARY INFORMATION: On June 22, 2009, the FAA issued AD 2009–12– 51, Amendment 39–15952 (74 FR 31167, June 30, 2009). That AD requires initial and repetitive visual inspections of certain reduction gearboxes (module M05) for oil leakage, repair if leaking, and repair of all affected modules as terminating action to the repetitive inspections. That AD was the result of reports of oil leaks from certain reduction gearbox (module M05) front casings. The engine manufacturer reported that the lubrication duct plug was not properly bonded/glued in place. That condition, if not corrected, could result in uncommanded in-flight engine shutdown, possible engine fire, and an emergency autorotation landing. erowe on DSK5CLS3C1PROD with RULES Actions Since AD 2009–12–51 Was Issued Since AD 2009–12–51 was issued, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, recently notified us that an unsafe condition may exist on Turbomeca Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines. EASA advises that Turbomeca has added five more serial numbers of the reduction gearboxes (module M05) that are affected, and has also added an alternative optional terminating action to the repetitive visual inspections. This AD requires initial and repetitive visual inspections of certain reduction gearboxes (module M05) for oil leakage, repair if leaking, and repair of all affected modules as optional terminating action to the repetitive inspections. We are issuing this AD to prevent uncommanded in-flight engine shutdown, possible engine fire, and an emergency autorotation landing. Relevant Service Information We have reviewed and approved the technical contents of Turbomeca S.A. Mandatory Service Bulletin (MSB) No. A292 72 0825, Version B, dated October VerDate Nov<24>2008 10:44 Dec 24, 2009 Jkt 220001 6, 2009, that describes procedures for visual inspections of affected reduction gearboxes (module M05) for oil leakage, repair if leaking, and repair of all affected modules as terminating action to the repetitive inspections. EASA classified this service bulletin as mandatory and issued AD 2009– 0245–E to ensure the airworthiness of these Turbomeca Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines in Europe. Bilateral Airworthiness Agreement This 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, EASA has kept the FAA informed of the situation described above. We have examined the findings of EASA, 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 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines of the same type design. We are issuing this AD to prevent uncommanded in-flight engine shutdown, possible engine fire, and an emergency autorotation landing. This AD requires initial and repetitive visual inspections of certain reduction gearboxes (module M05) for oil leakage, repair if leaking, and repair of all affected modules as terminating action to the repetitive inspections. You must use the service information described previously to perform the actions required by 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 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 PO 00000 Frm 00035 Fmt 4700 Sfmt 4700 68511 written relevant data, views, or arguments regarding this AD.

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) for Turbomeca Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 
1K1, 1S, and 1S1 turboshaft engines. That AD currently requires initial 
and repetitive visual inspections of certain reduction gearboxes 
(module M05) for oil leakage, repair if leaking, and repair of all 
affected modules as optional terminating action to the repetitive 
inspections. This AD requires the same actions, but adds five more 
serial numbers of the reduction gearboxes (module M05) that are 
affected, and adds an alternative optional terminating action to the 
repetitive visual inspections. This AD results from Turbomeca 
identifying five additional reduction gearboxes (module M05) affected, 
and adding an alternative optional terminating action to the repetitive 
visual inspections. We are issuing this AD to prevent uncommanded in-
flight engine shutdown, possible engine fire, and an emergency 
autorotation landing.

DATES: Effective January 12, 2010, the Director of the Federal Register 
approved the incorporation by reference of certain publications listed 
in the regulations as of January 12, 2010.

SUPPLEMENTARY INFORMATION: On June 22, 2009, the FAA issued AD 2009-12-
51, Amendment 39-15952 (74 FR 31167, June 30, 2009). That AD requires 
initial and repetitive visual inspections of certain reduction 
gearboxes (module M05) for oil leakage, repair if leaking, and repair 
of all affected modules as terminating action to the repetitive 
inspections. That AD was the result of reports of oil leaks from 
certain reduction gearbox (module M05) front casings. The engine 
manufacturer reported that the lubrication duct plug was not properly 
bonded/glued in place. That condition, if not corrected, could result 
in uncommanded in-flight engine shutdown, possible engine fire, and an 
emergency autorotation landing.

Actions Since AD 2009-12-51 Was Issued

    Since AD 2009-12-51 was issued, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, recently notified us that an unsafe condition may 
exist on Turbomeca Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 
1K1, 1S, and 1S1 turboshaft engines. EASA advises that Turbomeca has 
added five more serial numbers of the reduction gearboxes (module M05) 
that are affected, and has also added an alternative optional 
terminating action to the repetitive visual inspections. This AD 
requires initial and repetitive visual inspections of certain reduction 
gearboxes (module M05) for oil leakage, repair if leaking, and repair 
of all affected modules as optional terminating action to the 
repetitive inspections. We are issuing this AD to prevent uncommanded 
in-flight engine shutdown, possible engine fire, and an emergency 
autorotation landing.

Relevant Service Information

    We have reviewed and approved the technical contents of Turbomeca 
S.A. Mandatory Service Bulletin (MSB) No. A292 72 0825, Version B, 
dated October 6, 2009, that describes procedures for visual inspections 
of affected reduction gearboxes (module M05) for oil leakage, repair if 
leaking, and repair of all affected modules as terminating action to 
the repetitive inspections.
    EASA classified this service bulletin as mandatory and issued AD 
2009-0245-E to ensure the airworthiness of these Turbomeca Arriel 1A1, 
1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft 
engines in Europe.

Bilateral Airworthiness Agreement

    This 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, EASA has kept the FAA informed of the 
situation described above. We have examined the findings of EASA, 
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 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 
1E2, 1K1, 1S, and 1S1 turboshaft engines of the same type design. We 
are issuing this AD to prevent uncommanded in-flight engine shutdown, 
possible engine fire, and an emergency autorotation landing. This AD 
requires initial and repetitive visual inspections of certain reduction 
gearboxes (module M05) for oil leakage, repair if leaking, and repair 
of all affected modules as terminating action to the repetitive 
inspections. You must use the service information described previously 
to perform the actions required by 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 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-2009-0544; 
Directorate Identifier 2009-NE-17-AD'' in the subject line of your

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 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 at the 
address listed under ADDRESSES.
