Airworthiness Directives; Eurocopter France Model EC120B
Helicopters

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for
Eurocopter France Model EC120B helicopters. This AD results from
mandatory continuing airworthiness information (MCAI) originated by an
aviation authority of another country to identify and correct an unsafe
condition on a helicopter. The aviation authority of France, with which
we have a bilateral agreement, states in the MCAI:

    This Airworthiness Directive (AD) follows upon the discovery of
a batch of spherical thrust bearings which prove to be unfit for
flight.

This AD requires actions that are intended to address the unsafe
condition caused by the manufacture of a batch of spherical thrust
bearings that are not airworthy because they were not manufactured in
accordance with an approved type design. Failure of a spherical thrust
bearing during flight could cause the main rotor (M/R) system to
separate from the helicopter, which would be catastrophic.

DATES: This AD becomes effective on May 21, 2008.
    We must receive comments on this AD by July 7, 2008.

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance
of ADs related to MCAI. This streamlined process will allow us to adopt
MCAI safety requirements in a more efficient manner and will reduce
safety risks to the public. This process continues to follow all FAA AD
issuance processes to meet legal, economic, Administrative Procedure
Act, and Federal Register requirements. We also continue to meet our
technical decision-making responsibilities to identify and correct
unsafe conditions on U.S.-certificated products.
    This AD references the MCAI and related service information that we
considered in forming the engineering basis to correct the unsafe
condition. The AD contains text copied from the MCAI and for this
reason might not follow our plain language principles.

Discussion

    The Direction generale de l'aviation civile France (DGAC), the
Airworthiness Authority of the State of Design, has issued an MCAI for
the affected helicopters in the form of DGAC Airworthiness Directive
No. F-2006-040, dated February 15, 2006 (referred to after this as
``the MCAI''), to correct an unsafe condition for this French-
certificated helicopter. The MCAI states:

    This Airworthiness Directive (AD) follows upon the discovery of
a batch of spherical thrust bearings which prove to be unfit for
flight.

These are critical parts that retain the main rotor to the M/R hub and
flexes to allow the M/R blades to pitch. We were previously informed by
the manufacturer that all affected spherical thrust bearings had been
recovered by Eurocopter France. However, we recently learned that some
affected spherical thrust bearings have not been recovered and may
still be installed on some helicopters.

    You may obtain further information by examining the MCAI and
service information in the AD docket.

Relevant Service Information

    Eurocopter has issued Eurocopter Alert Telex No. 04A006, dated
January 27, 2006. The actions described in the MCAI are intended to
correct the same unsafe condition as that identified in the alert
telex.

FAA's Determination and Requirements of This AD

    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, the State of Design, we have
been notified of the unsafe condition described in the MCAI. We are
issuing this AD because we evaluated all pertinent information and
determined the unsafe condition exists and is likely to exist or
develop on other helicopters of the same type design.

Differences Between the AD and the MCAI

    We have reviewed the MCAI and agree with it. Therefore, there are
no differences.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because we
were previously informed by the manufacturer that all affected
spherical thrust bearings had been recovered by Eurocopter France.
However, we recently learned that some affected spherical thrust
bearings have not been recovered and may still be installed on some
helicopters. Failure of a spherical thrust bearing during flight could
cause the M/R system to separate from the helicopter, which would be
catastrophic. Therefore, we determined that notice and opportunity for
public comment before issuing this AD are impracticable and that good
cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2008-0489; Directorate
Identifier 2007-SW-59-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
    We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.

Cost of Compliance

    We estimate that this AD will affect about 96 helicopters of U.S.
Registry. However, the cost of the inspection to determine if one of
the affected spherical thrust bearings is installed is negligible. For
affected helicopters, we estimate that it will take about 4 work-hours
per helicopter to remove and replace a spherical thrust bearing. The
average labor rate is $80 per work-hour. Required parts will cost about
$4,500 per helicopter. Based on these figures, we estimate the cost of
this AD on U.S. operators to be $19,280 for the entire fleet, assuming
that the 4 spherical thrust bearings are replaced, or $4,820 per
helicopter.

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 an economic evaluation of the estimated costs to comply
with this AD and placed it in the AD docket.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2007-0226, dated August 24, 2006 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:

    [T]he FAA has published a set of new rules related to the fuel
tank safety, including the Special Federal Aviation Regulation 88
(SFAR 88).
    The JAA (Joint Aviation Authority) has issued an Interim Policy
JAA INT/POL 25/12, to recommend the application of a similar
requirement to the National Aviation Authorities (NAA) [of Europe].
    This recommendation was followed by French DGAC, which rendered
the compliance to JAA INT/POL 25/12 mandatory for all ATR Aircraft.
    Under this regulation, all holders of type certificates are
required to conduct a design review of their fuel tank systems
against explosion risk. It also requires the development and
implementation of maintenance and inspection instructions to
maintain the safety of the fuel tank system. To answer JAA INT/POL
25/12, and in accordance with SFAR 88 requirements and guideline,
ATR carried out a safety review on the fuel tank systems and zones
adjacent to the fuel tanks on all ATR models using relevant safety
assessment methods of JAR 35.1309.
    As a result of this safety review, ATR developed for ATR 42 the
modification 05355 (SB (service bulletin) ATR42-28-0039), and for
ATR 72 the modification 05356 (SB ATR72-28-1019). Those
modifications consist in the installation of fuses adapters on
wiring entering the fuel tanks and current limitation devices. For
ATR 72 aircraft, the modification also requires replacement of the
high level sensors with new sensors having shorter harness.

The modification also includes related investigative and corrective
actions, which include inspecting the electrical harness for correct
installation and adjusting the harness as necessary, and, for Model
ATR42 airplanes, inspecting the bonding strap for correct installation
and adjusting the bonding strap. You may obtain further information by
examining the MCAI in the AD docket.
    The FAA has examined the underlying safety issues involved in fuel
tank explosions on several large transport airplanes, including the
adequacy of existing regulations, the service history of airplanes
subject to those regulations, and existing maintenance practices for
fuel tank systems. As a result of those findings, we issued a
regulation titled ``Transport Airplane Fuel Tank System Design Review,
Flammability Reduction and Maintenance and Inspection Requirements''
(66 FR 23086, May 7, 2001). In addition to new airworthiness standards
for transport airplanes and new maintenance requirements, this rule
included Special Federal Aviation Regulation No. 88 (``SFAR 88,''
Amendment 21-78, and subsequent Amendments 21-82 and 21-83).
    Among other actions, SFAR 88 requires certain type design (i.e.,
type certificate (TC) and supplemental type certificate (STC)) holders
to substantiate that their fuel tank systems can prevent ignition
sources in the fuel tanks. This requirement applies to type design
holders for large turbine-powered transport airplanes and for
subsequent modifications to those airplanes. It requires them to
perform design reviews and to develop design changes and maintenance
procedures if their designs do not meet the new fuel tank safety
standards. As explained in the preamble to the rule, we intended to
adopt airworthiness directives to mandate any changes found necessary
to address unsafe conditions identified as a result of these reviews.
    In evaluating these design reviews, we have established four
criteria intended to define the unsafe conditions associated with fuel
tank systems that require corrective actions. The percentage of
operating time during which fuel tanks are exposed to flammable
conditions is one of these criteria. The other three criteria address
the failure types under evaluation: single failures, single failures in
combination with a latent condition(s), and in-service failure
experience. For all four criteria, the evaluations included
consideration of previous actions taken that may mitigate the need for
further action.
    The Joint Aviation Authorities (JAA) has issued a regulation that
is similar to SFAR 88. (The JAA is an associated body of the European
Civil Aviation Conference (ECAC) representing the civil aviation
regulatory authorities of a number of European States who have agreed
to co-operate in developing and implementing common safety regulatory
standards and procedures.) Under this regulation, the JAA stated that
all members of the ECAC that hold type certificates for transport
category airplanes are required to conduct a design review against
explosion risks.
    We have determined that the actions identified in this AD are
necessary to reduce the potential of ignition sources inside fuel
tanks, which, in combination with flammable fuel vapors, could result
in fuel tank explosions and consequent loss of the airplane.

Relevant Service Information

    ATR has issued Service Bulletins ATR42-28-0039, Revision 04, dated
June 12, 2007; and ATR72-28-1019, Revision 05, dated June 12, 2007. The
actions described in this service information are intended to correct
the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the

MCAI and service information referenced above. We are proposing this AD
because we evaluated all pertinent information and determined an unsafe
condition exists and is likely to exist or develop on other products of
the same type design.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD
would affect about 55 products of U.S. registry. We also estimate that
it would take about 150 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would cost about $23,000 per product. Where
the service information lists required parts costs that are covered
under warranty, we have assumed that there will be no charge for these
costs. As we do not control warranty coverage for affected parties,
some parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $1,925,000, or $35,000 per product.

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 above, 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); 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 proposed AD and placed it in the AD docket.

Subject

    (d) Air Transport Association (ATA) of America Code 28: Fuel.

Reason

    (e) The mandatory continuing airworthiness information (MCAI)
states:

    [T]he FAA has published a set of new rules related to the fuel
tank safety, including the Special Federal Aviation Regulation 88
(SFAR 88).
    The JAA (Joint Aviation Authority) has issued an Interim Policy
JAA INT/POL 25/12, to recommend the application of a similar
requirement to the National Aviation Authorities (NAA) [of Europe].
    This recommendation was followed by French DGAC, which rendered
the compliance to JAA INT/POL 25/12 mandatory for all ATR Aircraft.
    Under this regulation, all holders of type certificates are
required to conduct a design review of their fuel tank systems
against explosion risk. It also requires the development and
implementation of maintenance and inspection instructions to
maintain the safety of the fuel tank system. To answer JAA INT/POL
25/12, and in accordance with SFAR 88 requirements and guidelines,
ATR carried out a safety review on the fuel tank systems and zones
adjacent to the fuel tanks on all ATR models using relevant safety
assessment methods of JAR 35.1309.
    As a result of this safety review, ATR developed for ATR 42 the
modification 05355 (SB (service bulletin) ATR42-28-0039), and for
ATR 72 the modification 05356 (SB ATR72-28-1019). Those
modifications consist in the installation of fuses adapters on
wiring entering the fuel tanks and current limitation devices. For
ATR 72 aircraft, the modification also requires replacement of the
high level sensors with new sensors having shorter harness.

The modification also includes related investigative and corrective
actions, which include inspecting the electrical harness for correct
installation and adjusting the harness as necessary, and, for Model
ATR42 airplanes, inspecting the bonding strap for correct
installation and adjusting the bonding strap. The unsafe condition
is the potential of ignition sources inside fuel tanks, which, in
combination with flammable fuel vapors, could result in fuel tank
explosions and consequent loss of the airplane.

Actions and Compliance

    (f) Within 41 months after the effective date of this AD, unless
already done, modify the fuel system and do all applicable related
investigative and corrective actions according to the instructions
given by the applicable service bulletin listed in Table 1 of this
AD. Do all applicable related investigative and corrective actions
before further flight.

    Note: This AD differs from the MCAI and/or service information
as follows: The additional actions specified in the MCAI for

1019, Revision 05, dated June 12, 2007; as appropriate sources of
service information for accomplishing the required actions.
Operators that have done actions in accordance with previous issues
of the service bulletins may request an approval for an alternative
method of compliance (AMOC) according to paragraph (g) of this AD,
provided that the AMOC provides an acceptable level of safety.
