RIN 2120-AA64

Airworthiness Directives; Eurocopter France Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Eurocopter France (Eurocopter) Model AS350B3 and EC130B4 helicopters. 
This proposed AD would require revising the Limitations section of the 
Rotorcraft flight Manual (RFM) to reduce the starter generator 
operating current to 180 amperes (amps) and installing a placard in the 
instrument panel indicating the revised limitation. This proposed AD is 
prompted by the determination that the manufacturer-installed Aircraft 
Parts Corporation (APC) starter generator has exceeded the shaft horse 
power extractions allowed for Turbomeca engines. The proposed actions 
are intended to prevent the engine surge margin being reduced, which 
can result in engine failure.

DATES: We must receive comments on this proposed AD by September 28, 
2012.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your 
comments electronically.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued AD No. 
2006-0337, dated November 7, 2006, to correct an unsafe condition for 
the Eurocopter Model AS350B3 and EC130B4 helicopters. EASA advises that 
the power drawn by an APC 200 amps starter generator from the engine is 
above the consumption capacity for the specified Eurocopter model 
helicopters. Excessive power consumption of the starter generator 
reduces the engine surge margin, which can result in engine failure.

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 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other products of these same type designs.

Related Service Information

    Eurocopter has issued Alert Service Bulletins (ASBs) No. 01.00.57 
for the Model AS350B3 helicopters and No. 04A002 for the Model EC130B4 
helicopters. Both ASBs are Revision 1 and both are dated September 14, 
2006. The ASBs specify defining the limitation for the APC 200-amp 
starter generator. EASA classified these ASBs as mandatory and issued 
AD No. 2006-0337, dated November 7, 2006, to ensure the continued 
airworthiness of these helicopters.

Proposed AD Requirements

    This proposed AD would require, within the next 100 hours time-in-
service (TIS), revising the Limitations section of the RFM to reduce 
the starter generator rating to 180 amps and installing a placard on 
the instrument panel below the vehicle engine multifunction display 
indicating the starter generator reduced limitation: ``MAXIMUM 
CONTINUOUS GENERATOR LOAD 180A.''

Differences Between This Proposed AD and the EASA AD

    We would require that this proposed AD be accomplished within 100 
hours TIS, rather than 110 flight hours or 12 months as stated in the 
EASA AD.

Costs of Compliance

    We estimate that this proposed AD would affect 363 helicopters of 
U.S. registry. We estimate that operators may incur the following costs 
in order to comply with this AD: It would cost $21.25, assuming it 
takes 15 minutes to revise the RFM and install a placard on the 
instrument panel of each helicopter at an average labor rate of $85 per 
work hour, or $7,714 for the fleet.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation:
    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);
    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 proposed AD and placed it in the AD docket.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new 
Airworthiness Directive (AD):
