You may review the referenced service information at the FAA, Office of the Regional Counsel, Southwest Region, Discussion On March 29, 2012, at 77 FR 18967, 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 Eurocopter Model SA.315B Alouette III, SE.3160 Alouette III, SA.316B Alouette III, SA.316C Alouette III, SA.319B Alouette III, SA 3180– ALOUETTE ASTAZOU, SA 318B– ALOUETTE ASTAZOU, and SA 318C– ALOUETTE ASTAZOU helicopters. That NPRM proposed to require inspecting the cage of the free-wheel assembly for the correct alignment of the roller drive pocket recesses and replacing the free-wheel cage with an airworthy free-wheel cage if a defect exists. The proposed requirements were intended to prevent a loss of tail rotor drive 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, has issued EASA AD No. 2011– 0143, dated July 26, 2011 (AD 2011– 0143), to correct an unsafe condition for Eurocopter helicopters. EASA advises that during in-flight autorotation training, a pilot experienced a heavy jerk in the yaw control at the time of resynchronization. The free-wheel assembly of the helicopter had been replaced shortly before this flight. Internal inspection of the free-wheel assembly revealed incorrect positioning of the roller drive pocket recesses on the free-wheel cage.

ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Eurocopter France (Eurocopter) Model SA.315B Alouette III, SE.3160 Alouette III, SA.316B Alouette III, SA.316C Alouette III, SA.319B Alouette III, SA 3180–ALOUETTE ASTAZOU, SA 318B–ALOUETTE ASTAZOU, and SA 318 C–ALOUETTE ASTAZOU helicopters. This AD requires inspecting the cage of the free-wheel assembly for the correct alignment of the roller drive pocket recesses and replacing the freewheel cage with an airworthy freewheel cage if a defect exists. This AD was prompted by incorrect positioning of the roller drive pocket recesses on the tail rotor drive shaft free-wheel cage, which caused a pilot to experience a heavy jerk in the yaw control during inflight autorotation training. The requirements of this AD are intended to prevent a loss of tail rotor drive and subsequent loss of control of the helicopter.

This condition, if not corrected, could result in a temporary loss of rotor drive, jeopardizing flight safety, especially in phases of flight close to the ground. 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 18967, March 29, 2012). FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, 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 the EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed. Differences Between This AD and the EASA AD The EASA AD requires compliance within 110 flight hours or 5 months, whichever occurs first. This AD does not impose a calendar time requirement. Related Service Information Eurocopter has issued Alert Service Bulletin (ASB) No. Alouette-65.149, Revision 0, dated March 23, 2011, for model 3130, 313B, 3180, 318B, 318C, 3160, 316B, 316C, 319C and 319B helicopters; and ASB No. SA315–65.48, Revision 0, dated March 23, 2011, for model 315B helicopters, which specify removing and disassembling the freewheel assembly to check the free-wheel cage for correct positioning. EASA classified these ASBs as mandatory and issued AD 2011–0143 to ensure the continued airworthiness of these helicopters. mstockstill on DSK4VPTVN1PROD with RULES Costs of Compliance We estimate that this AD will affect 63 helicopters of U.S. Registry and that operators may incur the following costs to comply with this AD. • Inspecting the free-wheel cage assembly will require 8 work-hours at an average labor rate of $85 per hour, and required parts will cost $13, for a total cost per helicopter of $693, and a total cost to the U.S. operator fleet of $43,659. VerDate Mar<15>2010 16:35 Nov 23, 2012 Jkt 229001 • Modifying any affected free-wheel cage assembly will require 8 work hours and required parts will cost $1,986, for a total cost per helicopter of $2,666. 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 March 29, 2012, at 77 FR 18967, 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 Eurocopter Model 
SA.315B Alouette III, SE.3160 Alouette III, SA.316B Alouette III, 
SA.316C Alouette III, SA.319B Alouette III, SA 3180-ALOUETTE ASTAZOU, 
SA 318B-ALOUETTE ASTAZOU, and SA 318C-ALOUETTE ASTAZOU helicopters. 
That NPRM proposed to require inspecting the cage of the free-wheel 
assembly for the correct alignment of the roller drive pocket recesses 
and replacing the free-wheel cage with an airworthy free-wheel cage if 
a defect exists. The proposed requirements were intended to prevent a 
loss of tail rotor drive 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, has issued EASA AD 
No. 2011-0143, dated July 26, 2011 (AD 2011-0143), to correct an unsafe 
condition for Eurocopter helicopters. EASA advises that during in-
flight autorotation training, a pilot experienced a heavy jerk in the 
yaw control at the time of resynchronization. The free-wheel assembly 
of the helicopter had been replaced shortly before this flight. 
Internal inspection of the free-wheel assembly revealed incorrect 
positioning of the roller drive pocket recesses on the free-wheel cage. 
The subsequent off-

[[Page 70361]]

setting restricts the travel of the roller on its ramp and can cause, 
under high torque conditions, free-wheel slippage.
    This condition, if not corrected, could result in a temporary loss 
of rotor drive, jeopardizing flight safety, especially in phases of 
flight close to the ground.

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 18967, 
March 29, 2012).

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, 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 the EASA and determined the unsafe condition 
exists and is likely to exist or develop on other helicopters of these 
same type designs and that air safety and the public interest require 
adopting the AD requirements as proposed.

Differences Between This AD and the EASA AD

    The EASA AD requires compliance within 110 flight hours or 5 
months, whichever occurs first. This AD does not impose a calendar time 
requirement.

Related Service Information

    Eurocopter has issued Alert Service Bulletin (ASB) No. Alouette-
65.149, Revision 0, dated March 23, 2011, for model 3130, 313B, 3180, 
318B, 318C, 3160, 316B, 316C, 319C and 319B helicopters; and ASB No. 
SA315-65.48, Revision 0, dated March 23, 2011, for model 315B 
helicopters, which specify removing and disassembling the free-wheel 
assembly to check the free-wheel cage for correct positioning. EASA 
classified these ASBs as mandatory and issued AD 2011-0143 to ensure 
the continued airworthiness of these helicopters.

Costs of Compliance

    We estimate that this AD will affect 63 helicopters of U.S. 
Registry and that operators may incur the following costs to comply 
with this AD.
     Inspecting the free-wheel cage assembly will require 8 
work-hours at an average labor rate of $85 per hour, and required parts 
will cost $13, for a total cost per helicopter of $693, and a total 
cost to the U.S. operator fleet of $43,659.
     Modifying any affected free-wheel cage assembly will 
require 8 work hours and required parts will cost $1,986, for a total 
cost per helicopter of $2,666.

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.
