Airworthiness Directives; Airbus Model A300 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:

    [T]he FAA has published SFAR 88 (Special Federal Aviation 
Regulation 88). * * *
    Under this regulation, all holders of type certificates for 
passenger transport aircraft * * * are required to conduct a design 
review against explosion risks.
    This Airworthiness Directive (AD), which renders mandatory the 
modification of the fuel pump wiring against short circuit, is a 
consequence of this design review.

The unsafe condition is chafing of the fuel pump cables, which could 
result in short circuits leading to fuel pump

failure, intermittent operation, arcing, and possible fuel tank 
explosion. We are issuing this AD to require actions to correct the 
unsafe condition on these products.

DATES: This AD becomes effective October 2, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 2, 
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 June 28, 2007 (72 FR 
35368). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    [T]he FAA has published SFAR 88 (Special Federal Aviation 
Regulation 88). In their letters referenced 04/00/02/07/01-L296, 
dated March 4th, 2002 and 04/00/02/07/03-L024, dated February 3rd, 
2003, the JAA (Joint Aviation Authorities) recommended the 
application of a similar regulation to the National Aviation 
Authorities (NAA).
    Under this regulation, all holders of type certificates for 
passenger transport aircraft with either a passenger capacity of 30 
or more, or a payload capacity of 7,500 pounds (3402 kg) or more, 
which have received their certification since January 1st, 1958, are 
required to conduct a design review against explosion risks.
    This Airworthiness Directive (AD), which renders mandatory the 
modification of the fuel pump wiring against short circuit, is a 
consequence of this design review.
    Note: for A310 and A300-600 aircraft, refer to [EASA] AD 2006-
0284R1. [On March 7, 2007, the FAA issued a corresponding NPRM for 
Model A310 and A300-600 airplanes, which was published in the 
Federal Register (72 FR 11302, March 13, 2007.)]

The unsafe condition is chafing of the fuel pump cables, which could 
result in short circuits leading to fuel pump failure, intermittent 
operation, arcing, and possible fuel tank explosion. 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

    Based on the service information, we estimate that this AD affects 
about 29 products of U.S. registry. We also estimate that it takes 
about 72 work-hours per product to comply with the basic requirements 
of this AD. The average labor rate is $80 per work-hour. Required parts 
cost about $5,050 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 on U.S. operators to be $313,490, or $10,810 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.

Subject

    (d) Air Transport Association (ATA) of America Code 24: 
Electrical Power.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    [T]he FAA has published SFAR 88 (Special Federal Aviation 
Regulation 88). In their letters referenced 04/00/02/07/01-L296, 
dated March 4th, 2002 and 04/00/02/07/03-L024, dated February 3rd, 
2003, the JAA (Joint Aviation Authorities) recommended the 
application of a similar regulation to the National Aviation 
Authorities (NAA).
    Under this regulation, all holders of type certificates for 
passenger transport aircraft with either a passenger capacity of 30 
or more, or a payload capacity of 7,500 pounds (3402 kg) or more, 
which have received their certification since January 1st, 1958, are 
required to conduct a design review against explosion risks.
    This Airworthiness Directive (AD), which renders mandatory the 
modification of the fuel pump wiring against short circuit, is a 
consequence of this design review.

    Note: For A310 and A300-600 aircraft, refer to [EASA] AD 2006-
0284R1. [On March 7, 2007, the FAA issued a corresponding NPRM for 
Model A310 and A300-600 airplanes, which was published in the 
Federal Register (72 FR 11302, March 13, 2007.)]


The unsafe condition is chafing of the fuel pump cables, which could 
result in short circuits leading to fuel pump failure, intermittent 
operation, arcing, and possible fuel tank explosion.

Actions and Compliance

    (f) Within 31 months after the effective date of this AD, unless 
already done, modify the inner and outer fuel pumps wiring, route 1P 
and 2P harnesses in the LH (left-hand) wing and in the RH (right-
hand) wing, in accordance with the Accomplishment Instructions of 
Airbus Service Bulletin A300-24-0103, Revision 01, dated January 11, 
2007. Actions done before the effective date of this AD in 
accordance with Airbus Service Bulletin A300-24-0103, dated March 
15, 2006, for airplanes under configuration 1 as defined in the 
service bulletin, are acceptable for compliance with the 
requirements of this AD.
