RIN 2120-AA64
Airworthiness Directives; Airbus Model A330-200, 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:
Several cases have been reported of in-flight loss of the drive
strut fitting from the movable fairing of flap track No. 3.
Consequently, the flap track No. 3 fairing was detached from its aft
end, and found hanging. Investigations have shown that the
detachment of the aft lower drive strut fitting from the fairing
occurred due to the four bonded inserts being pulled out.
This condition, if not corrected, could lead to in-flight loss
of the affected aircraft parts, potentially resulting in injuries to
persons on the ground.
* * * * *
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 Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2008-0153, dated August 8, 2008 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
Several cases have been reported of in-flight loss of the drive
strut fitting from the movable fairing of flap track No. 3.
Consequently, the flap track No. 3 fairing was detached from its aft
end, and found hanging. Investigations have shown that the
detachment of the aft lower drive strut fitting from the fairing
occurred due to the four bonded inserts being pulled out.
This condition, if not corrected, could lead to in-flight loss
of the affected aircraft parts, potentially resulting in injuries to
persons on the ground.
For the reason described above, this AD requires the
modification of the movable flap track fairing No. 3, both Left Hand
(LH) and Right Hand (RH) side, and prohibits re-installation of
unmodified units.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Airbus has issued Mandatory Service Bulletins A330-57-3095,
Revision 02, dated April 3, 2008; and A340-57-4103, Revision 01, dated
April 3, 2008. 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
[[Page 15402]]
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
Based on the service information, we estimate that this proposed AD
would affect about 35 products of U.S. registry. We also estimate that
it would take about 19 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would cost about $647 per product. Where the
service information lists required parts costs that are covered under
warranty, we have assumed that there will be no charge for these costs.
As we do not control warranty coverage for affected parties, some
parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $75,845, or $2,167 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 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.

detachment of the aft lower drive strut fitting from the fairing
occurred due to the four bonded inserts being pulled out.
This condition, if not corrected, could lead to in-flight loss
of the affected aircraft parts, potentially resulting in injuries to
persons on the ground.
For the reason described above, this AD requires the
modification of the movable flap track fairing No. 3, both Left Hand
(LH) and Right Hand (RH) side, and prohibits re-installation of
unmodified units.
