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 A330 operator experienced a low level of the Yellow hydraulic
circuit due to a loose[ning] of check valve part number (P/N)
CAR401. During the inspection on the other two hydraulic systems,
the other three CAR401 check valves were also found to be loose with
their lock wire broken in two instances.
A340 aeroplanes are also equipped with the same high pressure
manifold check valves.
Investigations are on-going to determine the root cause of this
event.
Additional cases of CAR401 check valve loosening have been
experienced in service on aeroplanes having accumulated more than
1000 flight cycles (FC). The check valve fitted on the Yellow
hydraulic system is more affected, probably due to additional system
cycles induced by cargo door operation.
The loss of torque due to pressure cycles could contribute to
check valve loosening, resulting in a leak and finally the loss of
the associated hydraulic system and, in the worst case, of the three
hydraulic systems of the aeroplane.
* * * * *
The unsafe condition is the possible loss of all three hydraulic
systems, which could result in loss of control of the airplane. This AD
requires actions that are intended to address the unsafe condition
described in the MCAI.
DATES: This AD becomes effective December 14, 2009.

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
Emergency Airworthiness Directive 2009-0223-E, dated October 13, 2009
(referred to after this as ``the MCAI''), to correct an unsafe
condition for the specified products. The MCAI states:
An A330 operator experienced a low level of the Yellow hydraulic
circuit due to a loose[ning] of check valve part number (P/N)
CAR401. During the inspection on the other two hydraulic systems,
the other three CAR401 check valves were also found to be loose with
their lock wire broken in two instances.
A340 aeroplanes are also equipped with the same high pressure
manifold check valves.
Investigations are on-going to determine the root cause of this
event.
Additional cases of CAR401 check valve loosening have been
experienced in service on aeroplanes having accumulated more than
1000 flight cycles (FC). The check valve fitted on the Yellow
hydraulic system is more affected, probably due to additional system
cycles induced by cargo door operation.
The loss of torque due to pressure cycles could contribute to
check valve loosening, resulting in a leak and finally the loss of
the associated hydraulic system and, in the worst case, of the three
hydraulic systems of the aeroplane.
This AD requires to perform the following inspection programme
to detect any check valve loosening and, if necessary, apply the
associated corrective actions:
1st Step: On yellow and blue hydraulic circuits: lock wire
inspection, inspection for traces of seepage or black deposit, check
valve torque and red marking application.
2nd Step: On green hydraulic circuit: same inspections as
required in 1st Step and on yellow and blue hydraulic circuits:
inspection of check valves for condition.
Finally: On green, yellow and blue hydraulic circuits:
repetitive inspection of check valves for condition.
The unsafe condition is the possible loss of all three hydraulic
systems, which could result in loss of control of the airplane. The
inspection program involves a detailed inspection of the lock wire for
presence and integrity, a detailed inspection for traces of seepage or
black deposits, an inspection for proper torque, and a detailed
inspection to determine alignment of the check valve and manifold. The
corrective actions include replacing seal assemblies, replacing the
check valve, removing the lock wire, and re-torquing the check valve.
The required actions also include installing a new lock wire. You may
obtain further information by examining the MCAI in the AD docket.

Relevant Service Information
Airbus has issued All Operators Telexes A330-29A3111 and A340-
29A4086, both Revision 1, both 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 condition
exists and is likely to exist or develop on other products of the same
type design.
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
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because the
compliance time defined in the MCAI is 28 days for initial inspection.
Loss of torque could lead to loosening of the check valve. Loosening of
the check valve can lead to a hydraulic leak with possible loss of the
associated hydraulic system, and in the case of the loss of all three
hydraulic systems of the airplane. Loss of a hydraulic system could
result in reduced controllability and increased workload for the
flightcrew. Loss of all three hydraulic systems could result in loss of
control of the airplane. Therefore, we determined that notice and
opportunity for public comment before issuing this AD are impracticable
and that good cause exists for making this amendment effective in less
than 30 days.
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-2009-1092; Directorate
Identifier 2009-NM-219-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.

Subject
(d) Air Transport Association (ATA) of America Code 29:
Hydraulic Power.
Reason
(e) The mandatory continued airworthiness information (MCAI)
states:
An A330 operator experienced a low level of the Yellow hydraulic
circuit due to a loose[ning] of check valve part number (P/N)
CAR401. During the inspection on the other two hydraulic systems,
the other three CAR401 check valves were also found to be loose with
their lock wire broken in two instances.
A340 aeroplanes are also equipped with the same high pressure
manifold check valves.
[[Page 62210]]
Investigations are on-going to determine the root cause of this
event.
Additional cases of CAR401 check valve loosening have been
experienced in service on aeroplanes having accumulated more than
1000 flight cycles (FC). The check valve fitted on the Yellow
hydraulic system is more affected, probably due to additional system
cycles induced by cargo door operation.
The loss of torque due to pressure cycles could contribute to
check valve loosening, resulting in a leak and finally the loss of
the associated hydraulic system and, in the worst case, of the three
hydraulic systems of the aeroplane.
This AD requires to perform the following inspection programme
to detect any check valve loosening and, if necessary, apply the
associated corrective actions:
1st Step: On yellow and blue hydraulic circuits: lock wire
inspection, inspection for traces of seepage or black deposit, check
valve torque and red marking application.
2nd Step: On green hydraulic circuit: same inspections as
required in 1st Step and on yellow and blue hydraulic circuits:
inspection of check valves for condition.
Finally: On green, yellow and blue hydraulic circuits:
repetitive inspection of check valves for condition.
The unsafe condition is the possible loss of all three hydraulic
systems, which could result in loss of control of the airplane. The
inspection program involves a detailed inspection of the lock wire
for presence and integrity, a detailed inspection for traces of
seepage or black deposits, an inspection for proper torque, and a
detailed inspection to determine alignment of the check valve and
manifold. The corrective actions include replacing seal assemblies,
replacing the check valve, removing the lock wire, and re-torquing
the check valve. The required actions also include installing a new
lock wire.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Actions
(g) Do the actions required by paragraphs (g)(1) through (g)(3)
of this AD.
