ARRIUS 2F Turboshaft Engines AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. SUMMARY: We are adopting a new 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: srobinson on DSKHWCL6B1PROD with RULES On several ARRIUS 2F engines, the clearance between the P3 air pipe P/N 0319719180 and the rear right bulkhead P/N 0319998240 has been found to be too small. Investigations have shown that both P3 air pipe and rear right bulkhead were compliant to the design. The Turbomeca Engineering Department concluded that the tolerance of assembly established during the design could result in some rubbing between parts. Rubs between the pipe and the bulkhead may lead to premature wearing and finally rupture of the P3 air pipe. The loss of P3 air pressure would then force the fuel control system to idle which could have a detrimental effect in critical phases of flight. We are issuing this AD to prevent an uncommanded power loss, which could result in an emergency autorotation landing or accident. DATES: This AD becomes effective August 19, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 19, 2009. 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.

SUPPLEMENTARY INFORMATION: VerDate Nov<24>2008 15:15 Jul 14, 2009 Jkt 217001 34221 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 April 13, 2009 (74 FR 16809). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that: 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. On several ARRIUS 2F engines, the clearance between the P3 air pipe P/N 0319719180 and the rear right bulkhead P/N 0319998240 has been found to be too small. Investigations have shown that both P3 air pipe and rear right bulkhead were compliant to the design. The Turbomeca Engineering Department concluded that the tolerance of assembly established during the design could result in some rubbing between parts. Rubs between the pipe and the bulkhead may lead to premature wearing and finally rupture of the P3 air pipe. The loss of P3 air pressure would then force the fuel control system to idle which could have a detrimental effect in critical phases of flight. 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. 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. Costs of Compliance Based on the service information, we estimate that this AD will affect about 94 engines installed on helicopters of U.S. registry. We also estimate that it will take about 1 work-hour per engine to comply with this AD. The average labor rate is $80 per work-hour. Required parts will cost about $705 per engine. Based on these figures, we estimate the cost of the AD on U.S. operators to be $73,790. Our cost estimate is exclusive of possible warranty coverage.

Airworthiness Directives; Turbomeca S.A. ARRIUS 2F Turboshaft
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new 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:

On several ARRIUS 2F engines, the clearance between the P3 air
pipe P/N 0319719180 and the rear right bulkhead P/N 0319998240 has
been found to be too small.
Investigations have shown that both P3 air pipe and rear right
bulkhead were compliant to the design. The Turbomeca Engineering
Department concluded that the tolerance of assembly established
during the design could result in some rubbing between parts.
Rubs between the pipe and the bulkhead may lead to premature
wearing and finally rupture of the P3 air pipe. The loss of P3 air
pressure would then force the fuel control system to idle which
could have a detrimental effect in critical phases of flight.

We are issuing this AD to prevent an uncommanded power loss, which
could result in an emergency autorotation landing or accident.

DATES: This AD becomes effective August 19, 2009. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in this AD as of August 19, 2009.

ADDRESSES: The Docket Operations office is located at Docket Management

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 April 13, 2009 (74
FR 16809). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states that:

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.

Costs of Compliance

Based on the service information, we estimate that this AD will
affect about 94 engines installed on helicopters of U.S. registry. We
also estimate that it will take about 1 work-hour per engine to comply
with this AD. The average labor rate is $80 per work-hour. Required
parts will cost about $705 per engine. Based on these figures, we
estimate the cost of the AD on U.S. operators to be $73,790. Our cost
estimate is exclusive of possible warranty coverage.

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
the ADDRESSES section. Comments will be available in the AD docket
shortly after receipt.
