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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus transport category airplanes. This AD requires an 
inspection to determine if suspect part numbers (P/Ns) and serial 
numbers of certain Thales Avionics equipment are installed, and 
replacement of any suspect part with a modified part having a new P/N. 
This AD is prompted by reports of loss of the digital distance radio 
magnetic indicator and subsequent loss of both very high frequency 
omnidirectional range indicators, both distance measuring equipment, 
and one centralized maintenance computer. We are issuing this AD to 
prevent loss of navigation indications on the primary flight display 
requiring continuation of the flight on emergency instruments, which 
could lead to reduced ability to control the airplane in adverse 
conditions.

DATES: This AD becomes effective August 10, 2005.
    The incorporation by reference of certain publications listed in 
the AD is approved by the Director of the Federal Register as of August 
10, 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 Docket Management Facility office (telephone (800) 647-
5227) is located 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-2005-20474; the directorate 
identifier for this docket is 2004-NM-221-AD.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with an AD for certain Airbus Model A300 B2-203 and B4-203 airplanes; 
Model A310-200 and -300 series airplanes; and Model A300 B4-600, B4-
600R, and F4-600R series airplanes, and Model C4-605R Variant F 
airplanes (collectively called A300-600 series airplanes). That action, 
published in the Federal Register on March 3, 2005 (70 FR 10339), 
proposed to require an inspection to determine if suspect part numbers 
(P/Ns) and serial numbers of certain Thales Avionics equipment are 
installed, and replacement of any suspect part with a modified part 
having a new P/N.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment that has been 
submitted on the proposed AD.

Request To Expand Applicability

    One commenter, the airplane manufacturer, notes that French 
airworthiness directive F-2004-037, issued March 17, 2004, which also 
addresses the subject of the proposed AD, applies to Airbus Model A300 
B4-220 airplanes, as well as the other airplane models identified in 
the proposed AD. The commenter points out that the proposed AD does not 
mention Airbus Model A300 B4-220 airplanes.
    We agree with the commenter's statements, but find that we do not 
need to change the AD in this regard. Airbus Model A300 B4-220 
airplanes are not listed on the U.S. type certificate data sheet; thus, 
we do not need to issue an AD against those airplanes.

Explanation of Change to Applicability

    We have revised the applicability of this AD to identify model 
designations as published in the most recent type certificate data 
sheet for the affected models.

Conclusion

    We have carefully reviewed the available data, including the 
comment that was submitted, and determined that air safety and the 
public interest require adopting the AD with the change described 
previously. We have determined that this change will neither increase 
the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    This AD will affect about 158 Model A310-200 and -300 series 
airplanes, and Mode A300-600 series airplanes of U.S. registry. The 
required inspection will take about 1 work hour per airplane, at an 
average labor rate of $65 per work hour. Based on these figures, the 
estimated cost of this AD for these U.S. operators is $10,270, or $65 
per airplane.
    Currently, there are no affected Model A300 B2-203 and B4-203 
airplanes on the U.S. Register. However, if an affected airplane is 
imported and placed on the U.S. Register in the future, the required 
actions will take about 1 work hour, at an average labor rate of $65 
per work hour. Based on these figures, we

[[Page 38754]]

estimate the cost of this AD for Model A300 B2-203 and B4-203 series 
airplanes to be $65 per airplane.

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.
