14 CFR Part 39

[Docket No. FAA-2004-19527; Directorate Identifier 2004-NM-71-AD]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A310 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)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus Model A310 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). This proposed AD would 
require relocating contactor 9DG located at rack (relay box) 107VU and 
adding protective sleeves to the two wire (cable) looms near the door 
hinge of rack 107VU. This proposed AD is prompted by reports that 
interference was noticed during production between the wire looms 
located near the door hinge of rack 107VU and the terminals of 
contactor 9DG. We are proposing this AD to prevent possible short 
circuits in the wire looms supplying the fuel pump systems and the 
pitot probe heating system, which could lead to a possible loss of 
function of flight-critical systems and reduced controllability of the 
airplane.

DATES: We must receive comments on this proposed AD by December 6, 
2004.

SUPPLEMENTARY INFORMATION:

Docket Management System (DMS)

    The FAA has implemented new procedures for maintaining AD dockets 
electronically. As of May 17, 2004, new AD actions are posted on DMS 
and assigned a docket number. We track each action and assign a 
corresponding directorate identifier. The DMS AD docket number is in 
the form ``Docket No. FAA-2004-99999.'' The Transport Airplane 
Directorate identifier is in the form ``Directorate Identifier 2004-NM-
999-AD.'' Each DMS AD docket also lists the directorate identifier 
(``Old Docket Number'') as a cross-reference for searching purposes.

Comments Invited

    We invite you to submit any relevant written data, views, or 
arguments regarding this proposed AD. Send your comments to an address 
listed under ADDRESSES. Include ``Docket No. FAA-2004-19527; 
Directorate Identifier 2004-NM-71-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the proposed AD. We will 
consider all comments submitted by the closing date and may amend the 
proposed AD in light of those comments.
    We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact with FAA 
personnel concerning this proposed AD. Using the search function of our 
docket website, anyone can find and read the comments in any of our 
dockets, including the name of the individual who sent the comment (or 
signed the comment on behalf of an association, business, labor union, 
etc.). You can review the DOT's complete Privacy Act Statement in the

Discussion

    The Direction Generale de l'Aviation Civile (DGAC), which is the 
airworthiness authority for France, notified us that an unsafe 
condition may exist on certain Airbus Model A310 series airplanes; and 
Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4 
605R Variant F airplanes (collectively called A300-

[[Page 64261]]

600). The DGAC advises that it has received reports that interference 
was noticed during production between two wire (cable) looms located 
near the door hinge of rack (relay box) 107VU and the terminals of 
contactor 9DG located at rack 107VU. This condition could also be 
present on any airplane that has embodied in service any revision of 
Airbus Service Bulletin A310-30-2030 or Service Bulletin A300-30-6017. 
This condition, if not corrected, could result in short circuits in the 
wire looms supplying the fuel pump systems and the pitot probe heating 
system, which could lead to a possible loss of function and reduced 
controllability of the airplane.

Relevant Service Information

    Airbus has issued Service Bulletin A310-24-2087 (for Model A310 
series airplanes); and Service Bulletin A300-24-6081 (for Model A300 
B4-600, B4-600R, and F4-600R series airplanes; and Model C4 605R 
Variant F airplanes (collectively called A300-600)); both Revision 01, 
both dated December 18, 2003. The service bulletins describe procedures 
for relocating contactor 9DG and adding protective sleeves to the two 
wire looms located near the door hinge of rack 107VU. Accomplishing the 
actions specified in the service information is intended to adequately 
address the unsafe condition. The DGAC mandated the service information 
and issued French airworthiness directive F-2003-412, dated November 
12, 2003, to ensure the continued airworthiness of these airplanes in 
France.

FAA's Determination and Requirements of the Proposed AD

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for products of this type design that are certificated for 
operation in the United States.
    Therefore, we are proposing this AD, which would require 
accomplishing the actions specified in the service information 
described previously.

Costs of Compliance

    This proposed AD would affect about 167 airplanes of U.S. registry. 
The proposed actions would take about 3 work hours per airplane, at an 
average labor rate of $65 per work hour. Required parts would cost 
about $290 per airplane. Based on these figures, the estimated cost of 
the proposed AD for U.S. operators is $80,995, or $485 per airplane.

Regulatory Findings

    We have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    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 proposed AD. See the ADDRESSES section for a location 
to examine the regulatory evaluation.
