Airworthiness Directives; Airbus Model A330-200 and -300 Series 
Airplanes and Model A340-200 and -300 Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. 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 an 
aviation product. The MCAI describes the unsafe condition as:

    An A340 operator has reported an uncommanded engine N[deg]4 shut 
down during taxi after landing.
    The root cause of this event has been identified as failure of 
the fuel pump Non Return Valve (NRV) preventing the collector cell 
jet pump from working. This led to engine N[deg]4 collector cell 
fuel level to drop below the pump inlet and consequently causing 
engine N[deg]4 flame out.
* * * * *
    Multiple NRV failures in combination with failure modes trapping 
fuel could potentially increase the quantity of unusable fuel on 
aircraft possibly leading to fuel starvation which could result in 
engine in-flight shut down and would constitute an unsafe condition.
* * * * *

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective October 14, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 14, 
2009.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on April 29, 2009 (74 
FR 19464). That NPRM proposed to correct

[[Page 46323]]

an unsafe condition for the specified products. The MCAI states:

    An A340 operator has reported an uncommanded engine N[deg]4 shut 
down during taxi after landing.
    The root cause of this event has been identified as failure of 
the fuel pump Non Return Valve (NRV) preventing the collector cell 
jet pump from working. This led to engine N[deg]4 collector cell 
fuel level to drop below the pump inlet and consequently causing 
engine N[deg]4 flame out.
    A330 aircraft which have a similar design are also impacted by 
this issue.
    Multiple NRV failures in combination with failure modes trapping 
fuel could potentially increase the quantity of unusable fuel on 
aircraft possibly leading to fuel starvation which could result in 
engine in-flight shut down and would constitute an unsafe condition.
    To prevent such an event, this Airworthiness Directive (AD) 
requires a periodic operational test to check the correct operation 
of NRV and to apply the associated corrective actions.

The corrective action includes replacing any failed NRV with a new NRV. 
You may obtain further information by examining the MCAI in the AD 
docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received.

Request To Clarify Applicability Statement and Paragraphs (f)(1) and 
(f)(2) of the NPRM

    Airbus suggests that we revise the NPRM to specify all models in 
the Applicability statement and in paragraphs (f)(1) and (f)(2) of the 
proposed AD.
    We agree. For clarity, we have revised the applicability statement 
and paragraphs (f)(1), (f)(2), (f)(3)(i), and (f)(3)(ii) of this AD to 
identify all affected models as specified in the applicable type 
certificate data sheet.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the changes described previously. We determined that these 
changes will not increase the economic burden on any operator or 
increase the scope of the AD.

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 required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD affects 50 products of U.S. registry. We 
also estimate that it takes about 5 work-hours per product to comply 
with the basic requirements of this AD. The average labor rate is $80 
per work-hour. Based on these figures, we estimate the cost of this AD 
to the U.S. operators to be $20,000, or $400 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 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 a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

2009-18-19 Airbus: Amendment 39-16016. Docket No. FAA-2009-0381; 
Directorate Identifier 2009-NM-008-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective October 
14, 2009.

Affected ADs

    (b) None.

 Applicability

    (c) This AD applies to the airplanes identified in paragraphs 
(c)(1) and (c)(2) of the AD, certificated in any category.
    (1) Airbus Model A330-201, -202, -203, -223, -243, -301, -302, -
303, -321, -322, -323, -341, -342, and -343 series airplanes, all 
serial numbers.
    (2) Airbus Model A340-211, -212, -213, -311, -312, and -313 
series airplanes, all serial numbers.

Subject

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

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    An A340 operator has reported an uncommanded engine N[deg]4 shut 
down during taxi after landing.

[[Page 46324]]

    The root cause of this event has been identified as failure of 
the fuel pump Non Return Valve (NRV) preventing the collector cell 
jet pump from working. This led to engine N[deg]4 collector cell 
fuel level to drop below the pump inlet and consequently causing 
engine N[deg]4 flame out.
    A330 aircraft which have a similar design are also impacted by 
this issue.
    Multiple NRV failures in combination with failure modes trapping 
fuel could potentially increase the quantity of unusable fuel on 
aircraft possibly leading to fuel starvation which could result in 
engine in-flight shut down and would constitute an unsafe condition.
    To prevent such an event, this Airworthiness Directive (AD) 
requires a periodic operational test to check the correct operation 
of NRV and to apply the associated corrective actions.
    The corrective action includes replacing any failed NRV with a 
new NRV.
