This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: During production of Arriel 1 and Arriel 2 Power Turbine (PT) wheels, geometric nonconformances on blade fir tree roots have ´ been detected by Turbomeca. Potentially non-conforming PT blades have been traced as having been installed on Module M04 (PT) listed in Mandatory Service Bulletin (MSB) A292 72 0827 for Arriel 1 engines and A292 72 2833 for Arriel 2 engines. The geometric non-conformities of the blades may potentially lead to a reduction in the fatigue resistance of PT blades to a lower level than their authorized in service use limit. This reduction of fatigue resistance can potentially result in blade release, which could cause an uncommanded in-flight shutdown. We are issuing this AD to prevent release of PT blades, which could result in an uncommanded in-flight shutdown and emergency autorotation landing. DATES: This AD becomes effective May 7, 2010. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of May 7, 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.

PO 00000 Frm 00024 Fmt 4700 Sfmt 4700 SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on December 23, 2009 (74 FR 68194). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Since issuance of initial version of AD 2009–0112 additional information is available: —The list of Modules M04 concerned by the restriction of the cycle use limit of these PT blades has been updated again: The serial numbers of Modules M04 which have been retrofitted are crossed out. However, no new affected Modules M04 have been identified. See figure 1 of the referenced ´ Turbomeca MSB. —Additional testing and analysis had been ´ carried out by Turbomeca which allows increasing the cyclic use limit of these PT blades to 5 000 flight cycles. Therefore this AD revises AD 2009–0112 and requires establishing the cyclic use limit of these PT blades to 5 000 flight cycles. For PT blades having reached a number of flight cycles superior or equal to 5 000, removal of Module M04, or PT wheel assembly, or PT blades is required prior to next flight. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the AD. These requirements take precedence over the actions copied from the MCAI. Costs of Compliance Based on the service information, we estimate that this AD will affect about 10 products of U.S. registry. We also estimate that it will take about 8 workhours per product to comply with this AD. The average labor rate is $80 per work-hour. Required parts will cost about $43,000 per product. Based on E:\FR\FM\02APR1.SGM 02APR1 Federal Register / Vol. 75, No. 63 / Friday, April 2, 2010 / Rules and Regulations these figures, we estimate the cost of the AD on U.S. operators to be $436,400. 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. wwoods2 on DSK1DXX6B1PROD with RULES_PART 1 Regulatory Findings We 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 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.

Affected ADs (b) This AD revises AD 2009–08–08, Amendment 39–15881. Applicability (c) This AD applies to: (1) Turbomeca Arriel 1B, 1D, and 1D1 turboshaft engines with the power turbine (PT) modules M04 installed, as listed by serial number (S/N) in Figure 1 of Turbomeca Alert Mandatory Service Bulletin (MSB) No. A292 72 0827, Version C, dated July 15, 2009; and (2) Turbomeca Arriel 2B and 2B1 turboshaft engines with the power turbine modules M04 installed, as listed by S/N in Figure 1 of Turbomeca Alert MSB No. A292 72 2833, Version C, dated July 15, 2009. (3) These engines are installed on, but not limited to, Eurocopter AS 350 B, AS 350 BA, AS 350 B1, AS 350 B2, AS 350 B3, and EC 130 B4 helicopters. Reason (d) European Aviation Safety Agency (EASA) AD No. 2009–0112R1, dated July 30, 2009, states: Since issuance of initial version of AD 2009–0112 additional information is available: —The list of Modules M04 concerned by the restriction of the cycle use limit of these PT blades has been updated again: The serial numbers of Modules M04 which have been retrofitted are crossed out. However no new affected Modules M04 have been identified. See figure 1 of the referenced ´ Turbomeca MSB. —Additional testing and analysis had been ´ carried out by Turbomeca which allows increasing the cyclic use limit of these PT blades to 5,000 flight cycles.

Actions and Compliance (e) Unless already done, do the following actions. (1) For engines with an affected Module M04 (PT module), which has accumulated 5,000 total PT cycles or more on the effective date of this AD, remove the PT blades from service before further flight. (2) For engines with an affected Module M04, which has accumulated fewer than 5,000 total PT cycles on the effective date of this AD, remove the PT blades from service before accumulating 5,000 total PT cycles. (3) After the effective date of this AD, do not install any PT blades removed as specified in paragraph (e)(1) or (e)(2) of this AD, into any engine. FAA AD Differences (f) Although the compliance section of EASA AD No. 2009–0112R1, dated July 30, 2009, states to replace the Module M04, or PT wheel assembly, or PT blades, this AD states to remove the PT blades from service. (g) Although EASA AD No. 2009–0112R1, dated July 30, 2009, applies to the Arriel 2B1A engine, this AD does not apply to that model because it has no U.S. type certificate.

Section 11125 of the Act amended Chapters 51 and 52 of the Internal Revenue Code of 1986 (IRC), 26 U.S.C., to repeal the provisions covering special (occupational) tax (SOT) on alcohol beverage producers and dealers, tax-free alcohol users, denatured spirits users and dealers, and persons claiming drawback for the manufacture of nonbeverage alcoholic products. The Act did not eliminate the recordkeeping and registration requirements that applied to alcohol beverage dealers (including all persons in the business of selling alcohol products fit for beverage use) and nonbeverage drawback claimants prior to the SOT repeal. Further, the Act did not eliminate the SOT and related registration requirements for certain tobacco occupations (manufacturer of tobacco products, manufacturer of cigarette papers and tubes, and export warehouse proprietor). The Alcohol and Tobacco Tax and Trade Bureau (TTB) is responsible for the administration of the provisions in Chapters 51 and 52 of the IRC relating to these tax, recordkeeping, and registration requirements, including the promulgation of regulations thereunder in chapter 1 of title 27 of the Code of Federal Regulations.

With regard to tobacco products and cigarette papers and tubes, the temporary rule added a new subpart D to 27 CFR part 46 (Miscellaneous Regulations Relating to Tobacco Products and Cigarette Papers and Tubes) in order to consolidate in one place the SOT provisions contained in 27 CFR parts 40 (Manufacture of Tobacco Products, Cigarette Papers and Tubes, and Processed Tobacco) and 44 (Exportation of Tobacco Products and Cigarette Papers and Tubes, without Payment of Tax, or with Drawback of Tax). This new subpart D also borrowed regulations from 27 CFR part 31 (Alcohol Beverage Dealers) to reflect SOT policy positions developed through rulemaking involving the alcohol beverage dealer’s tax, including provisions relating to multiple businesses conducted by the same person at the same place, liability of partners, payment of the special tax, special tax stamps, and abatement or refund of special taxes. In addition, the temporary rule included a number of miscellaneous regulatory amendments to remove no longer needed references to the SOT. The amendments made by T.D. TTB–79 are discussed in more detail in the preamble of that document. In conjunction with the publication of the temporary rule, TTB also published on July 28, 2009, a notice of proposed rulemaking, Notice No. 96, in the Federal Register (74 FR 37426). This notice invited the submission of public comments on the regulatory amendments contained in the temporary rule, with the comment period closing on September 28, 2009. The Bureau did not receive any comments on the temporary rule in response to Notice No. 96. Accordingly, for the reasons set forth in the preamble of T.D. TTB–79, we have determined that it is appropriate to adopt that temporary rule as a final rule without change.

Airworthiness Directives; Turbomeca ARRIEL 1B, 1D, 1D1, 2B, and 
2B1 Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are revising an existing airworthiness directive (AD) for 
the products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) issued by an aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as:

    During production of Arriel 1 and Arriel 2 Power Turbine (PT) 
wheels, geometric non-conformances on blade fir tree roots have been 
detected by Turbom[eacute]ca. Potentially non-conforming PT blades 
have been traced as having been installed on Module M04 (PT) listed 
in Mandatory Service Bulletin (MSB) A292 72 0827 for Arriel 1 
engines and A292 72 2833 for Arriel 2 engines.
    The geometric non-conformities of the blades may potentially 
lead to a reduction in the fatigue resistance of PT blades to a 
lower level than their authorized in service use limit. This 
reduction of fatigue resistance can potentially result in blade 
release, which could cause an uncommanded in-flight shutdown.

    We are issuing this AD to prevent release of PT blades, which could 
result in an uncommanded in-flight shutdown and emergency autorotation 
landing.

DATES: This AD becomes effective May 7, 2010. The Director of the 
Federal Register approved the incorporation by reference of certain 
publications listed in this AD as of May 7, 2010.

ADDRESSES: The Docket Operations office is located at Docket Management 
Facility, U.S. Department of Transportation, 1200 New Jersey Avenue,

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on December 23, 2009 
(74 FR 68194). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    Since issuance of initial version of AD 2009-0112 additional 
information is available:

--The list of Modules M04 concerned by the restriction of the cycle 
use limit of these PT blades has been updated again: The serial 
numbers of Modules M04 which have been retrofitted are crossed out. 
However, no new affected Modules M04 have been identified. See 
figure 1 of the referenced Turbom[eacute]ca MSB.
--Additional testing and analysis had been carried out by 
Turbom[eacute]ca which allows increasing the cyclic use limit of 
these PT blades to 5 000 flight cycles.

    Therefore this AD revises AD 2009-0112 and requires establishing 
the cyclic use limit of these PT blades to 5 000 flight cycles.
    For PT blades having reached a number of flight cycles superior 
or equal to 5 000, removal of Module M04, or PT wheel assembly, or 
PT blades is required prior to next flight.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we required different actions 
in this AD from those in the MCAI in order to follow FAA policies. Any 
such differences are described in a separate paragraph of the AD. These 
requirements take precedence over the actions copied from the MCAI.

Costs of Compliance

    Based on the service information, we estimate that this AD will 
affect about 10 products of U.S. registry. We also estimate that it 
will take about 8 work-hours per product to comply with this AD. The 
average labor rate is $80 per work-hour. Required parts will cost about 
$43,000 per product. Based on

[[Page 16665]]

these figures, we estimate the cost of the AD on U.S. operators to be 
$436,400.

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 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 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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

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

2009-08-08R1 Turbomeca S.A.: Amendment 39-16245. Docket No. FAA-
2009-0302; Directorate Identifier 2009-NE-09-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective May 7, 
2010.

Affected ADs

    (b) This AD revises AD 2009-08-08, Amendment 39-15881.

Applicability

    (c) This AD applies to:
    (1) Turbomeca Arriel 1B, 1D, and 1D1 turboshaft engines with the 
power turbine (PT) modules M04 installed, as listed by serial number 
(S/N) in Figure 1 of Turbomeca Alert Mandatory Service Bulletin 
(MSB) No. A292 72 0827, Version C, dated July 15, 2009; and
    (2) Turbomeca Arriel 2B and 2B1 turboshaft engines with the 
power turbine modules M04 installed, as listed by S/N in Figure 1 of 
Turbomeca Alert MSB No. A292 72 2833, Version C, dated July 15, 
2009.
    (3) These engines are installed on, but not limited to, 
Eurocopter AS 350 B, AS 350 BA, AS 350 B1, AS 350 B2, AS 350 B3, and 
EC 130 B4 helicopters.

Reason

    (d) European Aviation Safety Agency (EASA) AD No. 2009-0112R1, 
dated July 30, 2009, states:

    Since issuance of initial version of AD 2009-0112 additional 
information is available:

--The list of Modules M04 concerned by the restriction of the cycle 
use limit of these PT blades has been updated again: The serial 
numbers of Modules M04 which have been retrofitted are crossed out. 
However no new affected Modules M04 have been identified. See figure 
1 of the referenced Turbom[eacute]ca MSB.
--Additional testing and analysis had been carried out by 
Turbom[eacute]ca which allows increasing the cyclic use limit of 
these PT blades to 5,000 flight cycles.

We are issuing this AD to prevent release of PT blades, which could 
result in an uncommanded in-flight shutdown and emergency 
autorotation landing.

Actions and Compliance

    (e) Unless already done, do the following actions.
    (1) For engines with an affected Module M04 (PT module), which 
has accumulated 5,000 total PT cycles or more on the effective date 
of this AD, remove the PT blades from service before further flight.
    (2) For engines with an affected Module M04, which has 
accumulated fewer than 5,000 total PT cycles on the effective date 
of this AD, remove the PT blades from service before accumulating 
5,000 total PT cycles.
    (3) After the effective date of this AD, do not install any PT 
blades removed as specified in paragraph (e)(1) or (e)(2) of this 
AD, into any engine.

FAA AD Differences

    (f) Although the compliance section of EASA AD No. 2009-0112R1, 
dated July 30, 2009, states to replace the Module M04, or PT wheel 
assembly, or PT blades, this AD states to remove the PT blades from 
service.
    (g) Although EASA AD No. 2009-0112R1, dated July 30, 2009, 
applies to the Arriel 2B1A engine, this AD does not apply to that 
model because it has no U.S. type certificate.

Other FAA AD Provisions

    (h) Alternative Methods of Compliance (AMOCs): The Manager, 
Engine Certification Office, FAA, has the authority to approve AMOCs 
for this AD, if requested using the procedures found in 14 CFR 
39.19.
