Model A310 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to all Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-2C, 
B4-103, and B4-203 series airplanes, that currently requires a one-time 
inspection of the space between the fuel quantity indication (FQI) 
probes and any adjacent structures for minimum clearance, and 
corrective action if necessary. This amendment expands the 
applicability in the existing AD and requires the subject one-time 
inspection on additional airplanes. The actions specified by this AD 
are intended to prevent the possibility of electrical arcing to the 
fuel tank if the airplane should be struck by lightning. Such arcing 
could create a potential ignition source within the fuel tank and an 
increased risk of a fuel tank explosion and fire. This action is 
intended to address the identified unsafe condition.

DATES: Effective April 9, 2004.
    The incorporation by reference of certain publications, as listed 
in the regulations, is approved by the Director of the Federal Register 
as of April 9, 2004.
    The incorporation by reference of a certain other publication, as 
listed in the regulations, was approved previously by the Director of 
the Federal Register as of August 1, 2001 (66 FR 34088, June 27, 2001).

ADDRESSES: The service information referenced in this AD may be 
obtained from Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac 
Cedex, France. This information may be examined at the Federal Aviation 
Administration (FAA), Transport Airplane Directorate, Rules Docket, 
1601 Lind Avenue, SW., Renton, Washington; or at the Office of the 
Federal Register, 800 North Capitol Street, NW., suite 700, Washington, 
DC.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 2001-13-09, 
amendment 39-12289 (66 FR 34088, June 27, 2001), which is applicable to 
all Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-2C, B4-103, and B4-203 
series airplanes, was published in the Federal Register on October 2, 
2003 (68 FR 56799). The action proposed to require a one-time 
inspection of the space between the fuel quantity indication (FQI) 
probes and any adjacent structures for minimum clearance, and 
corrective action if necessary.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the comments received.

Request for an Alternative Method of Compliance (AMOC)

    One commenter states that in 1999 it began replacing the factory-
installed fuel quantity indicating system (FQIS) on its A300-600 series 
airplanes with a Goodrich system, certified by Supplemental Type 
Certificate (STC) 00092BO. In addition, the commenter states that, as 
of January 2001, all its airplanes were modified per the Goodrich STC, 
which, due to increased clearance by an improved design, provides a 
greater level of safety than the factory-installed system. The 
commenter asks that the FQIS that is installed per the Goodrich STC be 
included as a second method of compliance, or that the proposed AD be 
revised to include credit for the airplanes already modified.
    The FAA cannot agree to other methods of compliance since no 
supporting data that such installation would provide an acceptable 
level of safety were provided to us to substantiate the commenter's 
request. For airplanes that have been previously modified, altered, or 
repaired in the areas addressed by these inspections, the operator may 
not need or be able to accomplish the requirements of the proposed AD. 
In this situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance in accordance 
with paragraph (d)(1) of this

[[Page 10320]]

AD. The request should include a description of changes to the design 
that will ensure the continued airworthiness of the affected airplanes 
in lieu of the required inspections. No change to the final rule is 
necessary in this regard.
    A second commenter states that it is the STC holder for the FQI 
probes that replace the fuel height probes developed by the original 
equipment manufacturer. The probes are replaced with a Goodrich-
designed FQI probe installed per STC 00092BO. The commenter states that 
the STC has been implemented by Goodrich customers and they are 
requesting assistance to obtain compliance with the requirements of the 
proposed AD. The commenter proposes to develop a service bulletin to 
perform a one-time inspection of the STC installation. The commenter 
would provide substantiating data to the FAA for review and approval 
after the service bulletin is developed. The commenter asks that the 
service bulletin be approved as an AMOC to the proposed AD. Records 
substantiating the inspections and corrective actions would be provided 
to the FAA by operators. The commenter adds that this approach was 
previously implemented by Goodrich for STC ST00020BO and the related 
AD. The commenter suggests that we review the suggested compliance 
option for the STC and provide a recommendation for the preferred 
approach for implementation. The commenter adds that, depending on the 
schedule for release of the proposed AD, it can prepare and provide the 
STC service bulletin for incorporation into the proposed AD. The 
commenter asks that we inform them if this approach is viable, and 
include the lead time required by our office for such incorporation.
    We cannot approve the use of a document that does not yet exist, 
and in consideration of the urgency of the identified unsafe condition 
and the amount of time that has already elapsed since the proposed AD 
was issued, we have determined that further delay of this final rule is 
not appropriate. However, if a new service bulletin is developed in the 
future, the commenter may request approval to use it as an alternative 
method of compliance under the provisions of paragraph (d)(1) of this 
final rule.

Conclusion

    After careful review of the available data, including the comments 
noted above, we have determined that air safety and the public interest 
require the adoption of the rule as proposed.

Cost Impact

    There are approximately 115 airplanes of U.S. registry that will be 
affected by this AD.
    The inspection that is currently required by AD 2001-13-09 takes 
about 7 work hours per airplane to accomplish, at an average labor rate 
of $65 per work hour. Based on these figures, the cost impact of the 
currently required inspection is estimated to be $455 per airplane.
    It will take about 5 work hours per airplane to accomplish the new 
inspection, specified in Airbus Service Bulletin A310-28-2145, at an 
average labor rate of $65 per work hour. Based on these figures, the 
cost impact of this inspection is estimated to be $325 per airplane.
    It will take about 10 work hours per airplane to accomplish the new 
inspection of the wing fuel tank, and about 5 work hours per airplane 
to accomplish the new inspection of the trim fuel tank, specified in 
Airbus Service Bulletin A300-28-6065, at an average labor rate of $65 
per work hour. Based on these figures, the cost impact of these 
inspections is estimated to be $650 per wing fuel tank, and $325 per 
trim fuel tank, per airplane.
    The cost impact figures discussed above are based on assumptions 
that no operator has yet accomplished any of the requirements of this 
AD action, and that no operator would accomplish those actions in the 
future if this AD were not adopted. The cost impact figures discussed 
in AD rulemaking actions represent only the time necessary to perform 
the specific actions actually required by the AD. These figures 
typically do not include incidental costs, such as the time required to 
gain access and close up, planning time, or time necessitated by other 
administrative actions.

Regulatory Impact

    The regulations adopted herein 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. Therefore, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.
