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:
An A340-642 operator reported [fault messages ``Main Fuel Pump
4'' and ``Eng 4 Stall/Surge''] * * * and finally the engine had an
auto shutdown [along] with [fault message ``Engine 4 Fail''] * * *.
* * * * *
Simultaneous loss of at least two Main Pumps along with other
potential failures related to the in-service event may lead to a
dual engine loss.
* * * * *
This AD requires actions that are intended to address the unsafe
condition described in the MCAI.
DATES: This AD becomes effective December 9, 2010.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of December 9,
2010.
We must receive comments on this AD by January 10, 2011.

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 2010-0013, dated January 26, 2010 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
An A340-642 operator reported a Main Fuel Pump 4 fault that
occurred during descent. Afterwards it was followed by a 2 times Eng
4 Stall/Surge Message and finally the engine had an auto shutdown
with Message Engine 4 Fail.
Analysis of the A340-500/600 aircraft fuel-pump electrical-
circuit design has shown that when a main fuel pump becomes
unserviceable and the fuel pressure indication system indicates
abnormal High (HI) pressure, these unwanted conditions occur:
--There is no Electronic Centralized Aircraft Monitor (ECAM) caution
or fault light of the unserviceable fuel pump.
--The crew cannot manually set the standby fuel pump to `ON' because
of the main pump pressure abnormal HI condition. Simultaneous loss
of at least two Main Pumps along with other potential failures
related to the in-service event may lead to a dual engine loss.
This AD mandates the modification of the main and standby pump
wiring logic which will let the related standby fuel pump be set
`ON' irrespective of the status of the main fuel pump pressure
switch in each of the conditions that follow:
--After the main fuel pump becomes unserviceable;
--When the push-button switch of the related main fuel pump is set
to `OFF', even if the fuel pump pressure indicates abnormally HI.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Airbus has issued Mandatory Service Bulletin A340-28-5050,
including Appendix 1, dated October 8, 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
[[Page 71539]]
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-2010-1110; Directorate
Identifier 2010-NM-052-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.
