Airworthiness Directives; Airbus Model A380-800 Series 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 inspection in production and on in-service aircraft, a 
number of OverHeat Detection System (OHDS) installation non-
conformities have been identified along the bleed air ducting.
    Some installation issues which may lead to a degraded leak 
detection capability have been reported. In case of hot air leakage, 
the potential degradation of the OHDS would not allow preventing 
damages to structure or components, and therefore could lead to an 
unsafe condition.
* * * * *
Nonconforming installation or a failure of the OHDS could allow 
undetected leakage of bleed air from the hot engine/auxiliary power 
unit causing damage to the airplane structure and various airplane 
components and systems. This AD requires actions that are intended to 
address the unsafe condition described in the MCAI.

DATES: This AD becomes effective November 24, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of November 24, 
2010.
    We must receive comments on this AD by December 27, 2010.

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 2009-0265, dated December 16, 2009 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During inspection in production and on in-service aircraft, a 
number of OverHeat Detection System (OHDS) installation non-
conformities have been identified along the bleed air ducting.
    Some installation issues which may lead to a degraded leak 
detection capability have been reported. In case of hot air leakage, 
the potential degradation of the OHDS would not allow preventing 
damages to structure or components, and therefore could lead to an 
unsafe condition.
    To ensure that in-service aeroplanes are free of such non-
conformities, EASA AD 2009-0066 required an inspection of the OHDS 
installation along the bleed air ducting and, in case of findings, 
to bring back the installation into the compliant configuration. 
That AD required a complete inspection for some MSN, and a partial 
inspection for MSN 15, 20 and 22. This partial inspection has now 
been assessed to be insufficient to cover the unsafe condition.
    This [EASA] AD, which supersedes EASA AD 2009-0066, requires to 
perform:
    <bullet> An additional inspection on MSN 15, 20 and 22 to render 
it complete, and
    <bullet> A complete inspection on additional MSN.

Nonconforming installation or a failure of the OHDS could allow 
undetected leakage of bleed air from the hot engine/auxiliary power 
unit causing damage to the airplane structure and various airplane 
components and systems. You may obtain further information by examining 
the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A380-36-8009, 
including Service Bulletin Report Sheet, dated December 7, 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.

[[Page 68694]]

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-2010-1102; Directorate 
Identifier 2010-NM-016-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.

as appropriate, or lacking a principal inspector, your local Flight 
Standards District Office. The AMOC approval letter must 
specifically reference this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered
