Airworthiness Directives; Airbus Model A330-300, A340-200, and
A340-300 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed 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.
* * * * ** *
The proposed AD would require actions that are intended to address
the unsafe condition described in the MCAI.

Discussion
The European Aviation Safety Agency (EASA), which is the aviation
authority for the Member States of the European Community, has issued
EASA Airworthiness Directive 2010-0021, dated February 9, 2010
(referred to after this as ``the MCAI''), 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.
Relevant Service Information
Airbus has issued All Operators Telexes (AOTs) A330-55A3040 and
A340-55A4036, both Revision 02, both dated September 30, 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 Proposed 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 proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
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 proposed 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 proposed 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 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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
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 proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39

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 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:

FAA AD Differences
Note 1: This AD differs from the MCAI and/or service information
as follows: No differences.
Other FAA AD Provisions
(k) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, FAA, has the authority to approve
AMOCs for this AD, if requested using the procedures found in 14 CFR
39.19. Send information to ATTN: Vladimir Ulyanov, Aerospace
Engineer, International Branch, ANM-116, Transport Airplane
Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057-
3356; telephone (425) 227-1138; fax (425) 227-1149. Before using any
approved AMOC on any airplane to which the AMOC applies, notify your
principal maintenance inspector (PMI) or principal avionics
inspector (PAI), as appropriate, or lacking a principal inspector,
your local Flight Standards District Office. The AMOC approval
letter must specifically reference this AD.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: A federal agency may not conduct or
sponsor, and a person is not required to respond to, nor shall a
person be subject to a penalty for failure to comply with a
collection of information subject to the requirements of the
Paperwork Reduction Act unless that collection of information
displays a current valid OMB Control Number. The OMB Control Number
for this information collection is 2120-0056. Public reporting for
this collection of information is estimated to be approximately 5
minutes per response, including the time for reviewing instructions,
completing and reviewing the collection of information. All
responses to this collection of information are mandatory. Comments
concerning the accuracy of this burden and suggestions for reducing
the burden should be directed to the FAA at: 800 Independence Ave.,
