Airworthiness Directives; Airbus Model A330 Airplanes

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 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:

    During cruise, an A330 operator experienced a LH (left-hand) 
wing tank pump 1 low pressure message followed immediately 
by LH wing tank stand-by pump low pressure message, then LH wing 
tank pumps low pressure message. The flight crew opened the cross-
feed valve to feed the engine on LH wing from RH (right-hand) wing 
but RH wing tank pumps low-pressure message was displayed as well as 
advisory unbalanced fuel message. * * *
* * * * *
    It has been confirmed following fuel tank entry that outlet of 
the LH pump 2 canister had broken due to static overload.
    If this situation is not corrected, it can lead to the loss of 
fuel on both engines in flight * * * [and] a dual engine flameout * 
* *.

    This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective November 8, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of November 8, 
2007.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Emergency Airworthiness Directive 2007-0216-E, dated August 8, 2007 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    During cruise, an A330 operator experienced a LH (left-hand) 
wing tank pump 1 low pressure message followed immediately 
by LH wing tank stand-by pump low pressure message, then LH wing 
tank pumps low pressure message. The flight crew opened the cross-
feed valve to feed the engine on LH wing from RH (right-hand) wing 
but RH wing tank pumps low-pressure message was displayed as well as 
advisory unbalanced fuel message. It was reported that the cross-
feed was closed in accordance with applicable procedure and the 
aircraft was landed successfully.
    It has been identified that both engines were gravity fed above 
the certified gravity feed ceiling for a brief period of time.
    It has been confirmed following fuel tank entry that outlet of 
the LH pump 2 canister had broken due to static overload.
    If this situation is not corrected, it can lead to the loss of 
fuel on both engines in flight which constitutes an unsafe 
condition.
    To prevent a dual engine flameout, this Emergency Airworthiness 
Directive (EAD) mandates an operational procedure which covers the 
scenario of small or large engine feed line ruptures and to add also 
a method to recover fuel in the unlikely event that the engine on 
the affected wing fails to restart at or below the gravity feed 
ceiling.

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

Relevant Service Information

    Airbus has issued A330 Temporary Revision 4.02.00/39, dated June 
21, 2007, to the Airbus A330 Airplane Flight Manual (AFM). 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 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between the 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 FAA policies. Any such differences are 
highlighted in a NOTE within the AD.

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 on 
the incident airplane, the outlet of the LH pump 2 canister to 
the engine fuel feed line was found ruptured. During cruise, the 
flightcrew followed existing AFM procedures for a FUEL L WING PUMPS LO 
PR ECAM caution, which resulted in an unwanted fuel transfer through 
the ruptured part from the right wing inner tank to the left wing inner 
tank. Under certain conditions, this could result in the loss of fuel 
to both engines and a dual engine flameout. 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-2007-0073; Directorate 
Identifier 2007-NM-229-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 https://
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.

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.

2. The FAA amends Sec.  39.13 by adding the following new AD:

2007-22-04 Airbus: Amendment 39-15240. Docket No. FAA-2007-0073; 
Directorate Identifier 2007-NM-229-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective November 
8, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to all Airbus Model A330 airplanes, 
certificated in any category, all certified models, all serial 
numbers.

Subject

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

Reason

    (e) The mandatory continued airworthiness information (MCAI) 
states:
    During cruise, an A330 operator experienced a LH (left-hand) 
wing tank pump 1 low pressure message followed immediately 
by LH wing tank stand-by pump low pressure message, then LH wing 
tank pumps low pressure message. The flight crew opened the cross-
feed valve to feed the engine on LH wing from RH (right-hand) wing 
but RH wing tank pumps low-pressure message was displayed as well as 
advisory unbalanced fuel message. It was reported that the cross-
feed was closed in accordance with applicable procedure and the 
aircraft was landed successfully.
    It has been identified that both engines were gravity fed above 
the certified gravity feed ceiling for a brief period of time.
    It has been confirmed following fuel tank entry that outlet of 
the LH pump 2 canister had broken due to static overload.
    If this situation is not corrected, it can lead to the loss of 
fuel on both engines in flight which constitutes an unsafe 
condition.
    To prevent a dual engine flameout, this Emergency Airworthiness 
Directive (EAD) mandates an operational procedure which covers the 
scenario of small or large engine feed line ruptures and to add also 
a method to recover fuel in the unlikely event that the engine on 
the affected wing fails to restart at or below the gravity feed 
ceiling.

Actions and Compliance

    (f) Within 10 days after the effective date of this AD, unless 
already done, revise the Procedures and Emergency sections of the 
Airbus A330 Airplane Flight Manual (AFM) to include the information 
in Airbus A330 Temporary Revision (TR) 4.02.00/39, dated June 21, 
2007. The TR revises the procedure to follow in the event of fuel 
pump low pressure warnings and adds operational procedures to follow 
in the event of a feed fuel line rupture.

    Note 1: The action required by paragraph (f) of this AD may be 
done by inserting into the appropriate AFM sections a copy of the TR 
listed in paragraph (f) of this AD. When this TR has been included 
in the general revisions of the AFM, the general revisions may be 
inserted into the AFM, provided the relevant information in the 
general revision is identical to that in the TR listed in paragraph 
(f) of this AD.


    Note 2: This AFM TR will be incorporated in another AFM TR 
associated to the introduction of Flight Warning Computer T2 
standard.

FAA AD Differences

    Note 3: This AD differs from the MCAI and/or service information 
as follows: No differences.
