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 inspections 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 * * *.
* * * * *
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.

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 2009-0066, dated March 19, 2009 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
During inspections 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 aircraft are free of such non-
conformities, this AD requires an inspection of the OHDS
installation along the bleed air ducting and, in case of findings
[any sensing element or insulation muff installed incorrectly], to
bring back the installation into the compliant configuration.
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. The inspection of the OHDS installation, for
certain airplanes, consists of inspecting the APU overheat sensing
elements APU 1 Loop A and B, the APU overheat sensing elements APU 2
Loop A and B, the crossbleed overheat sensing element, the forward
cargo compartment heating element, and the sensing element of the
overheat detection unit of the wing. For certain other airplanes,
inspecting the OHDS installation consists of inspecting the forward
cargo compartment heating element. You may obtain further information
by examining the MCAI in the AD docket.
Relevant Service Information
Airbus has issued Service Bulletin A380-36-8004, dated February 13,
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
[[Page 35781]]
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-2009-0644; Directorate
Identifier 2009-NM-059-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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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:
2009-15-09 Airbus: Amendment 39-15972. Docket No. FAA-2009-0644;
Directorate Identifier 2009-NM-059-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective August
5, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A380-841, -842, and -861
airplanes, certificated in any category, serial numbers 3, 5, 6, 8,
10, 11, 12, 13, 14, 15, 16, 20, and 22.
Subject
(d) Air Transport Association (ATA) of America Code 36:
Pneumatic.
Reason
(e) The mandatory continued airworthiness information (MCAI)
states:
During inspections 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 aircraft are free of such non-
conformities, this AD requires an inspection of the OHDS
installation along the bleed air ducting and, in case of findings
[any sensing element or insulation muff installed incorrectly], to
bring back the installation into the compliant configuration.
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. The inspection of the OHDS installation, for
certain airplanes, consists of inspecting the APU overheat sensing
elements APU 1 Loop A and B, the APU overheat sensing elements APU 2
Loop A and B, the crossbleed overheat sensing element, the forward
cargo compartment heating element, and the sensing element of the
overheat detection unit of the wing. For certain other airplanes,
inspecting the OHDS installation consists of inspecting the forward
cargo compartment heating element.
