Airworthiness Directives; Airbus Model A300-600 Series Airplanes; 
and Model A310 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:
* * * * *

    * * * the FAA set-up in January 1999 an Ageing Transport Systems 
Rulemaking Advisory Committee (ATSRAC) to investigate the potential 
safety issues in aging aircraft as a result of wear and degradation 
in their operating systems.
    Under this plan, all Holders of type Certificates aircraft are 
required to conduct a design review, to preclude the occurrence of 
potential unsafe conditions as the aircraft aged.
* * * * *

    The unsafe condition is degradation of the fuel system, which could 
result in loss of the airplane. We are issuing this AD to require 
actions to correct the unsafe condition on these products.

DATES: This AD becomes effective November 20, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 20, 
2007.

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 July 10, 2007 (72 FR 
37472). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    * * * the FAA issued in July 1996 an Aging Non-structural 
Systems plan to address the White House Commission an Aviation 
Safety and Security (WHCSS) report.
    To help fulfill the actions specified in this Aging Systems 
plan, the FAA set-up in January 1999 an Ageing Transport Systems 
Rulemaking Advisory Committee (ATSRAC) to investigate the potential 
safety issues in aging aircraft as a result of wear and degradation 
in their operating systems.
    Under this plan, all Holders of type Certificates aircraft are 
required to conduct a design review, to preclude the occurrence of 
potential unsafe conditions as the aircraft aged.
    Further to AIRBUS investigations on this subject, corrected 
measures intended to improve the design of A310 and A300-600 fleet 
against potential unsafe conditions as the aircraft aged, are 
rendered mandatory by this AD.

    The unsafe condition is degradation of the fuel system, which could 
result in loss of the airplane. The corrective actions include:
     Modify emergency power electrical routing.
     Inspect certain wire routes and do necessary corrective 
action (repair chafed or burned wiring, damaged clamps, and introduce 
self-vulcanizing silicone tape for wrapping the cable bundle at each 
clamping position).
     Secure electrical routing.
     Relocate temperature sensors and modify wires.
    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 58505]]

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

    Based on the service information, we estimate that this AD affects 
about 193 products of U.S. registry. We estimate that it takes about 
267 work hours per product to comply with this AD. The average labor 
rate is $80 per work-hour. Required parts cost about $17,637 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 this AD to be 
$7,526,421, or $38,997 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://dms.dot.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.
