Airworthiness Directives; Airbus Model A380-841, -842, and -861 
Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding an existing 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 flight test campaign of the A380-861 model (Engine 
Alliance powered), some cracks were found on the Movable Flap Track 
Fairing number 6 (MFTF6).
    These cracks were located at the pivot attachment support-ring 
and at the U-frame in the attachment area to aft-kinematic. In 
addition, delamination has been observed within the monolithic 
Carbon Fibre Reinforced Plastic (CFRP) structure around the pivot 
support-ring.
    This condition, if not corrected, could lead to in-flight loss 
of the MFTF6, potentially resulting in injuries to persons 
on the ground.
* * * * *
This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective March 10, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of March 10, 
2010.
    On May 28, 2009 (74 FR 22422, May 13, 2009), the Director of the

SUPPLEMENTARY INFORMATION:

Discussion

    On May 1, 2009, the FAA issued AD 2009-10-07, Amendment 39-15902 
(74 FR 22422, May 13, 2009). That AD required actions intended to 
address an unsafe condition on the products listed above.
    Since we issued that AD, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, has issued EASA Airworthiness Directive 2009-0152, 
dated July 14, 2009 (referred to after this as ``the MCAI''), to 
correct an unsafe condition for the specified products. The MCAI 
states:

    During the flight test campaign of the A380-861 model (Engine 
Alliance powered), some cracks were found on the Movable Flap Track 
Fairing number 6 (MFTF6).
    These cracks were located at the pivot attachment support-ring 
and at the U-frame in the attachment area to aft-kinematic. In 
addition, delamination has been observed within the monolithic 
Carbon Fibre Reinforced Plastic (CFRP) structure around the pivot 
support-ring.
    This condition, if not corrected, could lead to in-flight loss 
of the MFTF6, potentially resulting in injuries to persons 
on the ground.
    To prevent the risk of a MFTF6 detachment, EASA AD 
2008-0216 (which corresponds to FAA AD 2009-10-07) required an 
inspection programme in order to

[[Page 7932]]

detect cracks before they become critical and in case of findings to 
replace the MFTF6.
    This AD, which supersedes EASA AD 2008-0216:
     Cancels the MFTF6 General Visual Inspection 
requirement,
     Refers to Airbus Service Bulletin A380-57-8014 Revision 
1 * * *
     Introduces an optional terminating action [installing 
reinforced part].

    AD 2009-10-07 applies to all Airbus Model A380-841, -842, and -861 
airplanes. This AD retains the requirements of AD 2009-10-07. Airplanes 
were removed from the applicability of AD 2009-10-07 by excluding 
airplanes on which Airbus modification 68729 is done in production. 
This AD also revises the compliance time for the inspections of 
replaced parts. The compliance time is reduced for certain parts and 
extended for certain other parts, depending on the flight cycles since 
first installation of the part. The replacement parts must be inspected 
within the thresholds specified in paragraph (f)(1) of this AD.

Relevant Service Information

    Since we issued AD 2009-10-07, Airbus has issued Mandatory Service 
Bulletin A380-57-8014, Revision 01, dated June 5, 2009; and Service 
Bulletin A380-57-8017, dated June 5, 2009. 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-2010-0038; Directorate 
Identifier 2009-NM-110-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.

[[Page 7933]]

Subject

    (d) Air Transport Association (ATA) of America Code 57: Wings.

Reason

    (e) The mandatory continued airworthiness information (MCAI) 
states:
    During the flight test campaign of the A380-861 model (Engine 
Alliance powered), some cracks were found on the Movable Flap Track 
Fairing number 6 (MFTF6).
    These cracks were located at the pivot attachment support-ring 
and at the U-frame in the attachment area to aft-kinematic. In 
addition, delamination has been observed within the monolithic 
Carbon Fibre Reinforced Plastic (CFRP) structure around the pivot 
support-ring.
    This condition, if not corrected, could lead to in-flight loss 
of the MFTF6, potentially resulting in injuries to persons 
on the ground.
    To prevent the risk of a MFTF6 detachment, EASA AD 
2008-0216 required an inspection programme in order to detect cracks 
before they become critical and in case of findings to replace the 
MFTF6.
    This AD, which supersedes EASA AD 2008-0216:
     Cancels the MFTF6 General Visual Inspection 
requirement,
     Refers to Airbus Service Bulletin A380-57-8014 Revision 
1, * * *
     Introduces an optional terminating action.
