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 the A340-600 full scale fatigue test, cracks were found 
on left and right sides of the rear spar vertical cruciform at Frame 
47.
    This situation, if not corrected, can affect the aircraft 
structural integrity.

SUPPLEMENTARY INFORMATION:

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 2007-0207R1, dated November 7, 2007 (referred 
to after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During the A340-600 full scale fatigue test, cracks were found 
on left and right sides of the rear spar vertical cruciform at Frame 
47.
    This situation, if not corrected, can affect the aircraft 
structural integrity.
    Further to this full scale fatigue test completion, it has been 
determined that the current inspections values (thresholds and 
intervals) as specified in the ALI [Airworthiness Limitation Items] 
tasks 57.18.16 have to be reviewed in order to comply with 
certification requirements. Consequently AIRBUS Service Bulletin 
(SB) A340-57-5011 has been issued to supersede the ALI tasks 
57.18.16.
    This AD mandates a repetitive inspection program in order to 
detect any crack by means of two Non-Destructive Test (NDT) 
inspection methods (High Frequency Eddy Current and Ultra Sonic).
    This AD has been revised in order to exclude from the 
applicability section, A340-642 aircraft on which a terminating 
action modification 56026 or SB A340-57-5010 has been embodied and 
which consists of a large cut-out of the vertical cruciform flange 
in order to reduce the stress level in this critical area.

    The compliance times for the initial and repetitive inspections 
depend on the airplane configuration and weight

[[Page 8480]]

variant. For the initial inspections, the earliest compliance time is 
2,600 total flight cycles or 17,100 total flight hours, whichever 
occurs first, and the latest compliance time is 8,300 total flight 
cycles or 67,100 total flight hours, whichever occurs first. For the 
repetitive intervals, the shortest interval is 1,200 flight cycles or 
8,600 flight hours, whichever occurs first, and the longest interval is 
2,600 flight cycles or 17,200 flight hours, whichever occurs first. You 
may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A340-57-5011, 
including Appendix 01, dated June 27, 2007; and Service Bulletin A340-
57-5010, Revision 01, dated April 2, 2008. 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.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

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

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

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-2010-0128; Directorate 
Identifier 2009-NM-136-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.

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.

    This situation, if not corrected, can affect the aircraft 
structural integrity.
    Further to this full scale fatigue test completion, it has been 
determined that the current inspections values (thresholds and

[[Page 8481]]

intervals) as specified in the ALI (Airworthiness Limitation Items) 
tasks 57.18.16 have to be reviewed in order to comply with 
certification requirements. Consequently AIRBUS Service Bulletin 
(SB) A340-57-5011 has been issued to supersede the ALI tasks 
57.18.16.
    This AD mandates a repetitive inspection program in order to 
detect any crack by means of two Non-Destructive Test (NDT) 
inspection methods (High Frequency Eddy Current and Ultra Sonic).
    This AD has been revised in order to exclude from the 
applicability section, A340-642 aircraft on which a terminating 
action modification 56026 or SB A340-57-5010 has been embodied and 
which consists of a large cut-out of the vertical cruciform flange 
in order to reduce the stress level in this critical area.
