SUPPLEMENTARY INFORMATION: tkelley on DSK3SPTVN1PROD with RULES Discussion On May 9, 2012, at 77 FR 27144, the Federal Register published our Notice of Proposed Rulemaking (NPRM), which proposed to amend 14 CFR part 39 to include an AD that would apply to Agusta Model A109S helicopters, serial numbers up to and including 22151. That NPRM proposed to require compliance with specified portions of the manufacturer’s service bulletin to modify the electrical power distribution system by installing a ‘‘BATT BUS’’ Circuit Breaker Modification Kit, part number 109–0824–73–107, and testing for proper functioning of the electrical system. The proposed requirements were intended to prevent failure of the circuit breaker, loss of electrical power to instruments powered by the ‘‘BATT BUS’’ system, and subsequent loss of control of the helicopter. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, issued EASA AD No. 2009–0137, dated June 23, 2009, for the Agusta Model A109E helicopter to correct an unsafe electrical condition caused by an inadequately functioning circuit breaker that was not within design requirements. That EASA AD required installing a ‘‘BATT BUS’’ circuit breaker modification kit on Model A109E helicopters. Based on the unsafe condition created by this circuit breaker as described in EASA AD No. 2009– 0137, the FAA issued AD 2010–20–21 (75 FR 61341, October 5, 2010; Correction published at 75 FR 65224, October 22, 2010) to require installing a ‘‘BATT BUS’’ circuit breaker modification kit on Model A109E helicopters in the United States. Subsequently, EASA issued AD No. 2009–0264, dated December 15, 2009, to correct the same unsafe condition on the VerDate Mar<15>2010 16:04 Oct 22, 2012 Jkt 229001 Agusta Model A109S helicopter due to the design commonality between the electrical power distribution system of the Model A109E and A109S helicopters. The FAA is issuing this AD for the Model A109S helicopter to correct this same unsafe condition. Comments We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM (77 FR 27144, May 9, 2012). FAA’s Determination These helicopters have been approved by the aviation authority of Italy and are approved for operation in the United States. Pursuant to our bilateral agreement with Italy, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of the same type design and that air safety and the public interest require adopting the AD requirements as proposed. Differences Between This AD and the EASA AD This AD does not reference the calendar date of June 30, 2010, which has already passed. Related Service Information Agusta has issued Bollettino Tecnico No. 109S–35, dated December 11, 2009 (BT), which specifies modifying and testing the ‘‘BATT BUS’’ circuit breaker installation. EASA classified this BT as mandatory and issued AD No. 2009– 0264, dated December 15, 2009, to ensure the continued airworthiness of these helicopters. Costs of Compliance We estimate that this AD will affect 15 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. It will take about 8 work-hours per helicopter to install the ‘‘BATT BUS’’ circuit breaker modification kit at an average labor rate of $85 per workhour and required parts will cost about $471 per helicopter. Based on these figures, we estimate the total cost impact of this AD on U.S. operators to be $17,265. According to the Agusta service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage by Agusta. PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 Accordingly, we have included all costs in our cost estimate. 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 helicopters identified in this rulemaking action. Regulatory Findings 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 DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and (4) 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 an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION:

Discussion

    On May 9, 2012, at 77 FR 27144, the Federal Register published our 
Notice of Proposed Rulemaking (NPRM), which proposed to amend 14 CFR 
part 39 to include an AD that would apply to Agusta Model A109S 
helicopters, serial numbers up to and including 22151. That NPRM 
proposed to require compliance with specified portions of the 
manufacturer's service bulletin to modify the electrical power 
distribution system by installing a ``BATT BUS'' Circuit Breaker 
Modification Kit, part number 109-0824-73-107, and testing for proper 
functioning of the electrical system. The proposed requirements were 
intended to prevent failure of the circuit breaker, loss of electrical 
power to instruments powered by the ``BATT BUS'' system, and subsequent 
loss of control of the helicopter.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, issued EASA AD No. 
2009-0137, dated June 23, 2009, for the Agusta Model A109E helicopter 
to correct an unsafe electrical condition caused by an inadequately 
functioning circuit breaker that was not within design requirements. 
That EASA AD required installing a ``BATT BUS'' circuit breaker 
modification kit on Model A109E helicopters. Based on the unsafe 
condition created by this circuit breaker as described in EASA AD No. 
2009-0137, the FAA issued AD 2010-20-21 (75 FR 61341, October 5, 2010; 
Correction published at 75 FR 65224, October 22, 2010) to require 
installing a ``BATT BUS'' circuit breaker modification kit on Model 
A109E helicopters in the United States. Subsequently, EASA issued AD 
No. 2009-0264, dated December 15, 2009, to correct the same unsafe 
condition on the Agusta Model A109S helicopter due to the design 
commonality between the electrical power distribution system of the 
Model A109E and A109S helicopters. The FAA is issuing this AD for the 
Model A109S helicopter to correct this same unsafe condition.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM (77 FR 27144, 
May 9, 2012).

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Italy and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Italy, EASA, its technical representative, 
has notified us of the unsafe condition described in the EASA AD. We 
are issuing this AD because we evaluated all information provided by 
EASA and determined the unsafe condition exists and is likely to exist 
or develop on other helicopters of the same type design and that air 
safety and the public interest require adopting the AD requirements as 
proposed.

Differences Between This AD and the EASA AD

    This AD does not reference the calendar date of June 30, 2010, 
which has already passed.

Related Service Information

    Agusta has issued Bollettino Tecnico No. 109S-35, dated December 
11, 2009 (BT), which specifies modifying and testing the ``BATT BUS'' 
circuit breaker installation. EASA classified this BT as mandatory and 
issued AD No. 2009-0264, dated December 15, 2009, to ensure the 
continued airworthiness of these helicopters.

Costs of Compliance

    We estimate that this AD will affect 15 helicopters of U.S. 
Registry. We estimate that operators may incur the following costs in 
order to comply with this AD. It will take about 8 work-hours per 
helicopter to install the ``BATT BUS'' circuit breaker modification kit 
at an average labor rate of $85 per work-hour and required parts will 
cost about $471 per helicopter. Based on these figures, we estimate the 
total cost impact of this AD on U.S. operators to be $17,265.
    According to the Agusta service information, some of the costs of 
this AD may be covered under warranty, thereby reducing the cost impact 
on affected individuals. We do not control warranty coverage by Agusta. 
Accordingly, we have included all costs in our cost estimate.

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 helicopters identified in this 
rulemaking action.

Regulatory Findings

    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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979);
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction; and
    (4) 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 an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
