-----------------------------------------------------------------------
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:
One Long Range operator experienced a failure of one spoiler
servo-control, associated with surface deflection in flight and
hydraulic leak. On ground, this servo-control Part Number (P/N)
MZ4306000-02X was found with the maintenance cover broken.
Investigations showed that the rupture of the maintenance cover was
due to pressure pulse fatigue.
* * * The rupture of the maintenance cover in flight may result
in the deflection of the associated spoiler surface up to the null-
hinge position (loss of the hydraulic locking).
[[Page 46314]]
It may also result in the loss of the associated hydraulic system
(external leakage). In the worst case, the three hydraulic systems
may be affected, which constitutes an unsafe condition.
* * * * *
Loss of the three hydraulic systems could result in reduced
controllability of the airplane. We are issuing this AD to require
actions to correct the unsafe condition on these products.
DATES: This AD becomes effective October 14, 2009.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of October 14,
2009.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on March 26, 2009 (74
FR 13148). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
One Long Range operator experienced a failure of one spoiler
servo-control, associated with surface deflection in flight and
hydraulic leak. On ground, this servo-control Part Number (P/N)
MZ4306000-02X was found with the maintenance cover broken.
Investigations showed that the rupture of the maintenance cover was
due to pressure pulse fatigue.
The maintenance cover allows switching the servo-control from
``Operational'' to ``Maintenance'' modes. The same cover is
installed on all standard MZ spoiler servo-controls except on P/N
MZ4339390-12 and MZ4306000-12, which have a reinforced maintenance
cover. The rupture of the maintenance cover in flight may result in
the deflection of the associated spoiler surface up to the null-
hinge position (loss of the hydraulic locking). It may also result
in the loss of the associated hydraulic system (external leakage).
In the worst case, the three hydraulic systems may be affected,
which constitutes an unsafe condition.
For the reasons described above, this EASA (European Aviation
Safety Agency) AD requires the identification and the modification
of all standard MZ spoiler servo-controls with initial maintenance
cover (P/N MZ4339390-01X, -02X, -10X for position 1 and P/N
MZ4306000-01X, -02X, -10X for positions 2 to 6) into standard MZ
servo-controls with reinforced maintenance cover (P/N MZ4339390-12
for position 1 and P/N MZ4306000-12 for positions 2 to 6).
Loss of the three hydraulic systems could result in reduced
controllability of the airplane. You may obtain further information by
examining the MCAI in the AD docket.
Revised Service Information
We have reviewed Airbus Service Bulletin A330-27-3110, Revision 03,
dated September 3, 2008. We referred to Airbus Service Bulletin A330-
27-3110, Revision 02, dated March 2, 2007, as the appropriate source of
service information for accomplishing certain actions specified in the
NPRM. We have determined that the actions specified in Airbus Service
Bulletin A330-27-3110, Revision 03, dated September 3, 2008, are
essentially the same as the actions specified in Airbus Service
Bulletin A330-27-3110, Revision 02, dated March 2, 2007. Therefore, we
find that no additional work will be required for airplanes that have
done the requirements of this AD in accordance with Airbus Service
Bulletin A330-27-3110, Revision 02, dated March 2, 2007. We have
changed paragraphs (f)(2) through (f)(6) of this AD to refer to
Revision 03, dated September 3, 2008, of Airbus Service Bulletin A330-
27-3110. We have also changed paragraph (f)(7) of this AD to give
credit to operators who have accomplished the actions in accordance
with Airbus Service Bulletin A330-27-3110, Revision 02, dated March 2,
2007, as well as the earlier versions of the service bulletin.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received.
Request To Clarify Proposed Applicability
Airbus asks that the applicability specified in paragraph (c) of
the NPRM be clarified. Airbus notes that the language ``* * * except
those identified in paragraphs (c)(1) and (c)(2) of this AD'' is
misleading, because the exceptions are already included in paragraphs
(c)(1) and (c)(2) of the AD.
We agree with Airbus. We have changed paragraph (c) of this AD as
follows: ``This AD applies to Airbus Model A330-300, A340-200, and
A340-300 series airplanes; certificated in any category; as identified
in paragraphs (c)(1) and (c)(2) of this AD.''
Request To Clarify Paragraphs (f)(1), (f)(2)(i), and (f)(2)(ii) of the
NPRM
Airbus also asks that the words ``of the aircraft'' be added to the
applicable paragraphs after the words ``since first flight'' for
clarification. Airbus notes that the missing text is confusing to
operators, who are asking Airbus if ``since first flight'' refers to
flight hours on the equipment or flight hours on the airplane.
We agree with Airbus. It was our intent that the phrase ``since
first flight'' apply to the subject airplanes, not equipment.
Therefore, we have changed all applicable references in paragraphs
(f)(1) through (f)(6) of this AD to specify ``since first flight of the
airplane.''
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously. We determined that these
changes will not increase the economic burden on any operator or
increase the scope of the AD.
Differences Between This 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 our FAA policies. Any such differences
are highlighted in a note within the AD.
Costs of Compliance
Based on the service information, we estimate that this AD affects
16 products of U.S. registry. We also estimate that it takes 1 work-
hour per product to comply with the basic requirements of this AD. The
average labor rate is $80 per work-hour. Based on these figures, we
estimate the cost of the AD on U.S. operators to be $1,280, or $80 per
product.
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
[[Page 46315]]
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.
Examining the AD Docket
You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

Subject
(d) Air Transport Association (ATA) of America Code 27: Flight
controls.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
One Long Range operator experienced a failure of one spoiler
servo-control, associated with surface deflection in flight and
hydraulic leak. On ground, this servo-control Part Number (P/N)
MZ4306000-02X was found with the maintenance cover broken.
Investigations showed that the rupture of the maintenance cover was
due to pressure pulse fatigue.
The maintenance cover allows switching the servo-control from
``Operational'' to ``Maintenance'' modes. The same cover is
installed on all standard MZ spoiler servo-controls except on P/N
MZ4339390-12 and MZ4306000-12, which have a reinforced maintenance
cover. The rupture of the maintenance cover in flight may result in
the deflection of the associated spoiler surface up to the null-
hinge position (loss of the hydraulic locking). It may also result
in the loss of the associated hydraulic system (external leakage).
In the worst case, the three hydraulic systems may be affected,
which constitutes an unsafe condition.
For the reasons described above, this EASA (European Aviation
Safety Agency) AD requires the identification and the modification
of all standard MZ spoiler servo-controls with initial maintenance
cover (P/N MZ4339390-01X, -02X, -10X for position 1 and P/N
MZ4306000-01X, 02X, -10X for positions 2 to 6) into standard MZ
servo-controls with reinforced maintenance cover (P/N MZ4339390-12
for position 1 and P/N MZ4306000-12 for positions 2 to 6).
Loss of the three hydraulic systems could result in reduced
controllability of the airplane.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) For airplanes that have accumulated more than 8,500 total
flight cycles since first flight of the airplane as of the effective
date of this AD: Do the actions required by paragraphs (f)(1)(i) and
(f)(1)(ii) of this AD, as applicable.
(i) Within 3 months after the effective date of this AD:
Identify the part number of spoiler servo-controls installed on the
airplane at all positions in order to determine the number of
affected hydraulic circuits in accordance with the Accomplishment

Revision 01; or Airbus Mandatory Service Bulletin A340-27A4154,
Revision 01; both dated July 25, 2008; as applicable. If there is no
spoiler servo-control installed with a part number identified in
Table 1 of this AD, no further action is required by this paragraph.
(ii) If there is any spoiler servo-control installed with a part
number identified in Table 1 of this AD, do all applicable actions
required by paragraph (f)(2), (f)(3), or (f)(4) of this AD, as
applicable.
