Airworthiness Directives; Airbus Model A330-300, A340-200, and
A340-300 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
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:
Surface defects were visually detected on the rudder of one
Airbus A319 and one A321 in-service aeroplane. Investigation has
determined that the defects reported on both rudders corresponded to
areas that had been reworked in production. The investigation
confirmed that the defects were the result of de-bonding between the
skin and honeycomb core. Such reworks were also performed on some
rudders fitted on A330-300 and A340-200/-300 aeroplanes.
An extended de-bonding, if not detected and corrected, may
degrade the structural integrity of the rudder. The loss of the
rudder leads to degradation of the handling qualities and reduces
the controllability of the aeroplane.
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective May 26, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of May 26, 2011.

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 January 13, 2011 (76
FR 2284). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Surface defects were visually detected on the rudder of one
Airbus A319 and one A321 in-service aeroplane. Investigation has
determined that the defects reported on both rudders corresponded to
areas that had been reworked in production. The investigation
confirmed that the defects were the result of de-bonding between the
skin and honeycomb core. Such reworks were also performed on some
rudders fitted on A330-300 and A340-200/-300 aeroplanes.
An extended de-bonding, if not detected and corrected, may
degrade the structural integrity of the rudder. The loss of the
rudder leads to degradation of the handling qualities and reduces
the controllability of the aeroplane.
EASA AD 2009-0156 required inspections of specific areas and,
depending on findings, the application of corrective actions for
those rudders where production reworks have been identified.
This AD retains the requirements of EASA AD 2009-0156, which is
superseded, and in addition requires for the vacuum loss hole
restoration:
--A local ultrasonic inspection for reinforced area instead of the
local thermography inspection, which is maintained for non-
reinforced areas, and
--An additional work for aeroplanes on which this thermography
inspection has been performed in the reinforced area.
The inspections include vacuum loss inspections and repetitive
elasticity laminate checker inspections for defects including de-
bonding between the skin and honeycomb core of the rudder, and
ultrasonic inspections for defects on rudders on which temporary
restoration with resin or permanent vacuum loss hole restoration has
been performed. The corrective action is repair, if necessary. You may
obtain further information by examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
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
Currently, there are no affected airplanes on the U.S. Register.
However, if an affected airplane is imported and placed on the U.S.
Register in the future, the required actions would take about 21 work
hours, at an average labor rate of $85 per work hour. Based on these
figures, we estimate the cost of this AD to be $1,785 per airplane.
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
[[Page 22320]]
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 that 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 http://www.regulations.gov; 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 55:
Stabilizers.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Surface defects were visually detected on the rudder of one
Airbus A319 and one A321 in-service aeroplane. Investigation has
determined that the defects reported on both rudders corresponded to
areas that had been reworked in production. The investigation
confirmed that the defects were the result of de-bonding between the
skin and honeycomb core. Such reworks were also performed on some
rudders fitted on A330-300 and A340-200/-300 aeroplanes.
An extended de-bonding, if not detected and corrected, may
degrade the structural integrity of the rudder. The loss of the
rudder leads to degradation of the handling qualities and reduces
the controllability of the aeroplane.
* * * * *
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)(8)
of this AD, in accordance with the Instructions of Airbus All
Operators Telex (AOT) A330-55A3040 or A340-55A4036, both Revision
02, both dated September 30, 2009, as applicable.
(1) In the reinforced location of the rudder: Within 1,800
flight hours after the rudder has accumulated 13,000 total flight
cycles since first installation, or within 1,800 flight hours after
the effective date of this AD, whichever is later, do a vacuum loss
inspection to detect defects, including de-bonding between the skin
and honeycomb core of the rudder.
(2) In the trailing edge location of the rudder: Within 21
months after the rudder has accumulated 13,000 total flight cycles
since first installation, or within 21 months after the effective
date of this AD, whichever is later, do an elasticity laminate
checker inspection to detect defects, including de-bonding between
the skin and honeycomb core of the rudder. If no defects are found,
repeat the inspection two times at intervals not to exceed 4,500
flight cycles, but not fewer than 4,000 flight cycles from the most
recent inspection.
(3) In locations other than those identified in paragraphs
(g)(1) and (g)(2) of this AD (e.g., lower rib, upper edge, leading
edge, and other locations): Within 1,800 flight hours after the
rudder has accumulated 13,000 total flight cycles since first
installation, or within 1,800 flight hours after the effective date
of this AD, whichever is later, do an elasticity laminate checker
inspection to detect defects, including de-bonding between the skin
and honeycomb core of the rudder. Repeat the inspection thereafter
at intervals not to exceed 1,800 flight hours.
(4) If no defects are found during any inspection required by
paragraph (g)(3) of this AD: Within 21 months after the rudder has
accumulated 13,000 total flight cycles since first installation, or
within 21 months after the effective date of this AD, whichever is
later, do a vacuum loss inspection on the
[[Page 22321]]
other locations (e.g., lower rib, upper edge, leading edge, and
other locations) to detect defects, including de-bonding between the
skin and honeycomb core of the rudder.
(5) Accomplishment of the inspection required by paragraph
(g)(4) of this AD terminates the initial and repetitive inspections
required by paragraph (g)(3) of this AD.
(6) If any defect is found during any inspection required by
this AD, before further flight, repair using a method approved by
either the Manager, International Branch, ANM-116, Transport
Airplane Directorate, FAA; or the European Aviation Safety Agency
Airworthiness (EASA) (or its delegated agent).
(7) If no defects are found during any inspection required by
paragraphs (g)(1) and (g)(4) of this AD, before further flight,
restore the vacuum loss holes by doing a temporary restoration with
self-adhesive patches, a temporary restoration with resin, or a
permanent restoration. Do the applicable actions specified in
paragraph (g)(7)(i) or (g)(7)(ii) of this AD.
(i) For airplanes on which a temporary restoration with patch is
done: Within 900 flight hours after the restoration, do a detailed
inspection for defects of the restored area and repeat the
inspection thereafter at intervals not to exceed 900 flight hours
until the permanent restoration is done. Do the permanent
restoration within 21 months after the temporary restoration.
(ii) For airplanes on which a temporary restoration with resin
is done: Within 21 months after doing the temporary restoration, do
the permanent restoration.
(8) If any defect is found during any initial inspection
required by paragraphs (g)(1), (g)(3), and (g)(4) of this AD, at the
applicable time in paragraph (g)(8)(i) or (g)(8)(ii) of this AD:
