14 CFR Part 39

[Docket No. FAA-2005-20379; Directorate Identifier 2004-NM-174-AD; 
Amendment 39-14078; AD 2005-10-01]

Airworthiness Directives; Airbus Model A310 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus Model A310 series airplanes. This AD requires measuring the 
clearance between the compensator and the guide assembly of probe no. 1 
on the outboard fuel tanks, and performing corrective actions if 
necessary. This AD is prompted by the results of fuel system reviews 
conducted by the manufacturer. We are issuing this AD to prevent 
interference between the compensator and the guide assembly of probe 
no. 1, which could create an ignition source that could result in a 
fire or explosion.

DATES: This AD becomes effective June 16, 2005.
    The incorporation by reference of a certain publication listed in 
the AD is approved by the Director of the Federal Register as of June 
16, 2005.

ADDRESSES: For service information identified in this AD, contact 
Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, France.
    Docket: The AD docket contains the proposed AD, comments, and any 
final disposition. You can examine the AD docket on the Internet at 
http://dms.dot.gov, or in person at the Docket Management Facility 
office between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The

on the plaza level of the Nassif Building at the U.S. Department of 
Transportation, 400 Seventh Street, SW., room PL-401, Washington, DC. 
This docket number is FAA-2005-20379; the directorate identifier for 
this docket is 2004-NM-174-AD.

FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, 
International Branch, ANM-116, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-2125; fax (425) 227-1149.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with an AD for all Airbus Model A310 series airplanes. That action, 
published in the Federal Register on February 15, 2005 (70 FR 7700), 
proposed to require measuring the clearance between the compensator and 
the guide assembly of probe no. 1 on the outboard fuel tanks, and 
performing corrective actions if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been submitted on the proposed 
AD or on the determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this AD.

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 have 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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. See the ADDRESSES section for a location to 
examine the regulatory evaluation.

assembly of probe no. 1 on the left- and right-hand outboard fuel 
tanks, in accordance with the Accomplishment Instructions of Airbus 
Service Bulletin A310-28-2152, dated January 12, 2004. If the 
clearance between the compensator and the guide assembly is less 
than 3 mm, before further flight, modify the guide assembly of probe 
no. 1 to provide clearance of 3 mm or more between the compensator 
and the guide assembly, in accordance with the Accomplishment 
Instructions of the service bulletin.

Parts Installation

    (g) As of the effective date of this AD, no person may install
