Airworthiness Directives; Airbus Model A330-200, A330-300, 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:
During manufacturing of A330/A340 aircraft framework, cracks
have been found on Frame (FR) 12, left (LH) and right (RH) sides. It
has been confirmed that a defect of the FR12 forming tool press is
the root cause of the cracks.
If undetected such damage could affect, after propagation, the
structural integrity of the aircraft.
* * * * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective October 14, 2008.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of October 14,
2008.

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 June 24, 2008 (73 FR
35595). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
During manufacturing of A330/A340 aircraft framework, cracks
have been found on Frame (FR) 12, left (LH) and right (RH) sides. It
has been confirmed that a defect of the FR12 forming tool press is
the root cause of the cracks.
If undetected such damage could affect, after propagation, the
structural integrity of the aircraft.
In order to permit an early detection and repair of cracks on
FR12, LH and RH sides, this Airworthiness Directive (AD) mandates a
one time High Frequency Eddy Current (HFEC) inspection of FR12.
Corrective actions include, for certain findings, contacting Airbus for
repair instructions and doing the repair; repairing cracking (i.e.,
installing a new splice); and applying new protective coatings and
corrosion inhibitors. 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
[[Page 51907]]
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
We estimate that this AD will affect about 20 products of U.S.
registry. We also estimate that it will take about 3 work-hours per
product to comply with the basic requirements of this AD. The average
labor rate is $80 per work-hour. Required parts will cost about $0 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 parts. 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 this AD to the
U.S. operators to be $4,800, or $240 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 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 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 53:
Fuselage.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
During manufacturing of A330/A340 aircraft framework, cracks
have been found on Frame (FR) 12, left (LH) and right (RH) sides. It
has been confirmed that a defect of the FR12 forming tool press is
the root cause of the cracks.
If undetected such damage could affect, after propagation, the
structural integrity of the aircraft.
In order to permit an early detection and repair of cracks on
FR12, LH and RH sides, this Airworthiness Directive (AD) mandates a
one time High Frequency Eddy Current (HFEC) inspection of FR12.
Corrective actions include, for certain findings, contacting Airbus
for repair instructions and doing the repair; repairing cracking
(i.e., installing a new splice); and applying new protective
coatings and corrosion inhibitors.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Prior to the accumulation of 19,500 total flight cycles or
within 3 months after the effective date of this AD, whichever
occurs later: Perform a HFEC inspection at the LH and RH sides of
frame 12, in accordance with the instructions defined in Airbus
Mandatory Service Bulletin A330-53-3174 or A340-53-4177, both dated
October 10, 2007, as applicable. If no cracking is found, no further
action is required by this AD. Except as required by paragraph
(f)(2) of this AD, if any cracking is found, before further flight,
do the applicable corrective actions in accordance with the
instructions of Airbus Mandatory Service Bulletin A330-53-3174 or
A340-53-4177, as applicable.
(2) If any cracking is found that exceeds the limits specified
in Airbus Mandatory Service Bulletin A330-53-3174 or A340-53-4177,
both dated October 10, 2007, as applicable; or if any cracking is
found during any HFEC inspection of the cut-out area; before further
flight, contact Airbus for repair instructions and do the repair.
