Airworthiness Directives; Eurocopter France Model AS350B, BA, B1, 
B2, B3, C, D, D1, and EC130 B4 Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) for 
Eurocopter France (Eurocopter) Model AS350B, BA, B1, B2, B3, C, D, D1, 
and EC130 B4 helicopters that requires removing and modifying the fuel 
bleed lever. This amendment is prompted by some cases of loss of the 
fuel bleed lever in flight. If the tension of the control cable is too 
low, the cable may vibrate out of its notch, resulting in the fuel 
bleed lever separating from the hinge. The actions specified by this AD 
are intended to prevent a fuel bleed lever from separating and striking 
the tail rotor blade (blade), resulting in damage to or loss of a 
blade, and subsequent vibration and loss of control of the helicopter.

DATES: Effective March 21, 2005.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of March 21, 2005.

SUPPLEMENTARY INFORMATION: A proposal to amend 14 CFR part 39 to 
include an AD for the specified Eurocopter model helicopters was 
published in the Federal Register on September 8, 2004 (69 FR 54250). 
That action proposed to require removing and modifying the fuel bleed 
lever.
    The Direction Generale de L'Aviation Civile (DGAC), the 
airworthiness authority for France, notified the FAA that an unsafe 
condition may exist on Eurocopter Model EC 130 and the AS 350 
helicopters. The DGAC advises of some cases of loss of the fuel bleed 
lever in flight.
    Eurocopter has issued Alert Service Bulletin (ASB) Nos. 28A001 for 
the Model EC130 B4 and 28.00.16 for the civil version of the Model 
AS350B, BA, BB, B1, B2, B3, D, and the military version of the Model L1 
helicopters, both dated March 3, 2004. The ASB's specify removing and 
modifying the fuel bleed lever. The DGAC classified these ASB's as 
mandatory and issued AD Nos. F-2004-034 for the Model EC130 B4 pre-MOD 
073239 and F-2004-033 for the Model AS350B, BA, BB, B1, B2, B3, and D 
helicopters, pre-MOD 073239, both dated March 17, 2004, to ensure the 
continued airworthiness of these helicopters in France.
    These helicopter models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the 
applicable bilateral agreement, the DGAC has kept the FAA informed of 
the situation described above. The FAA has examined the findings of the 
DGAC, reviewed all available information, and determined that AD action 
is necessary for products of this type design that are certificated for 
operation in the United States.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were received on the 
proposal or the FAA's determination of the cost to the public. The FAA 
has determined that air safety and the public interest require the 
adoption of the rule as proposed.
    The FAA estimates that this AD will affect 624 helicopters of U.S. 
registry. It will take about 1 work hour per helicopter to modify the 
fuel bleed lever at an average labor rate of $65 per work hour and it 
will cost about $300 for consumable materials. Based on these figures, 
we estimate the total cost impact of the AD on U.S. operators to be 
$227,760.

Regulatory Findings

    We have 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 that the 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); 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 an economic evaluation of the estimated costs to comply 
with this AD. See the DMS to examine the economic evaluation.

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.
