Airworthiness Directives; Airbus Model A330-200, 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:

    One A320 operator has reported a disbond on the composite rudder 
control rod. Investigations conducted by the supplier revealed that 
this disbond is due to an incorrect low volume of resin in the fibre 
composite. The supplier and AIRBUS have confirmed that some rudder 
control rods installed on A330 and A340-200/-300 aircraft before 
delivery or delivered as spare are also affected by this defect. 
Rudder control rod rupture can lead, in the worst case, in 
combination with a yaw damper runaway to an unsafe condition.
* * * * *
The unsafe condition is reduced control of the airplane. We are issuing 
this AD to require actions to correct the unsafe condition on these 
products.

DATES: This AD becomes effective April 23, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 23, 
2008.

ADDRESSES: You may examine the AD docket on the Internet at: http://
www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC.

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 10, 2008 (73 
FR 1842). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    One A320 operator has reported a disbond on the composite rudder 
control rod. Investigations conducted by the supplier revealed that 
this disbond is due to an incorrect low volume of resin in the fibre 
composite. The supplier and AIRBUS have confirmed that some rudder 
control rods installed on A330 and A340-200/-300 aircraft before 
delivery or delivered as spare are also affected by this defect. 
Rudder control rod rupture can lead, in the worst case, in 
combination with a yaw damper runaway to an unsafe condition.
    In order to prevent such situation, this Airworthiness Directive 
(AD) requires a one time detailed visual inspection to identify the 
affected rods and to replace those affected by this issue.

The unsafe condition is reduced control of the airplane. 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

    We estimate that this AD will affect about 8 products of U.S. 
registry. We also estimate that it will take about 6 work-hours per 
product to comply with

[[Page 14669]]

the basic requirements of this AD. The average labor rate is $80 per 
work-hour. Labor costs may be covered under warranty as described in 
the service information. Based on these figures, we estimate the cost 
of this AD to the U.S. operators to be $3,840, or $480 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 27: Flight 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    One A320 operator has reported a disbond on the composite rudder 
control rod. Investigations conducted by the supplier revealed that 
this disbond is due to an incorrect low volume of resin in the fibre 
composite. The supplier and AIRBUS have confirmed that some rudder 
control rods installed on A330 and A340-200/-300 aircraft before 
delivery or delivered as spare are also affected by this defect. 
Rudder control rod rupture can lead, in the worst case, in 
combination with a yaw damper runaway to an unsafe condition.
    In order to prevent such situation, this Airworthiness Directive 
(AD) requires a one time detailed visual inspection to identify the 
affected rods and to replace those affected by this issue.

The unsafe condition is reduced control of the airplane.
