Airworthiness Directives; Airbus Model A330-301, -321, -322, -
341, and -342 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
is applicable to certain Airbus Model A330-301, -321, -322, -341, and -
342 series airplanes. This action requires replacement of the existing 
fasteners on the vertical web of stringers 13 and 20 of both wings with 
interference fasteners. This action is necessary to prevent fatigue 
cracking of the wing bottom skin and vertical webs, which could result 
in reduced structural integrity of the wing. This action is intended to 
address the identified unsafe condition.

SUPPLEMENTARY INFORMATION: The Direction Generale de l'Aviation Civile 
(DGAC), which is the airworthiness authority for, notified the FAA that 
an unsafe condition may exist on certain Airbus Model A330-301, -321, -
322, -341, and -342 series airplanes. The DGAC advises that, wing 
fatigue testing, cracks were found to be initiating and propagating at 
the bottom skin and in the vertical web of stringers 13 and 20, between 
ribs 1 and 2. This condition, if not corrected, could result in reduced 
structural integrity of the wing.

Explanation of Relevant Service Information

    Airbus has issued Service Bulletin A330-57-3019, Revision 02, dated 
September 14, 2000, which describes procedures for replacement of the 
existing fasteners on the vertical web of stringers 13 and 20 of both 
wings with interference fasteners. The replacement involves drilling 
and reaming of the holes; performing an eddy current test to inspect 
for cracks and performing corrective actions, if necessary; and 
installing new oversize fasteners. Accomplishment of the actions 
specified in the service bulletin is intended to adequately address the 
identified unsafe condition. The DGAC classified this service bulletin 
as mandatory and issued French airworthiness directive 2000-358-124(B), 
dated August 23, 2000, in order to assure the continued airworthiness 
of these airplanes in France.

FAA's Conclusions

    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. The FAA has examined the findings of 
the DGAC, reviewed all available information, and determined that AD 
action is necessary for products of this type design that are 
certificated for operation in the United States.

Explanation of Requirements of the Rule

    Since an unsafe condition has been identified that is likely to 
exist or develop on other airplanes of the same type design that may be 
registered in the United States at some time in the future, this AD 
will require accomplishment of the actions specified in the service 
bulletin described previously, except as discussed below.

Differences Between AD and Service Bulletin

    Operators should note that, although the service bulletin specifies 
that the manufacturer may be contacted for disposition of certain 
repair conditions, this AD requires the repair of those conditions to 
be accomplished in accordance with a method approved by either the FAA 
or the DGAC (or its delegated agent). In light of the type of repair 
that would be required to address the identified unsafe condition, and 
in consonance with existing blateral airworthiness agreements, the FAA 
has determined that, for this AD, a repair approved by either the FAA 
or the DGAC would be acceptable for compliance with this AD.

Cost Impact

    None of the airplanes affected by this action are on the U.S. 
Register. All airplanes included in the applicability of this rule 
currently are operated by non-U.S. operators under foreign registry; 
therefore, they are not directly affected by this AD action. However, 
the FAA considers that this rule is necessary to ensure that the unsafe 
condition is addressed in the event that any of these subject airplanes 
are imported and placed on the U.S. Register in the future.
    Should an affected airplane be imported and placed on the U.S. 
Register in the future, it would require approximately 10 work hours to 
accomplish the required replacement, at an average labor rate of $60 
per work hour. Required parts would cost approximately $1,030 per 
airplane. Based on these figures, the cost impact of this AD would be 
$1,630 per airplane.

Determination of Rule's Effective Date

    Since this AD action does not affect any airplane that is currently 
on the U.S. register, it has no adverse economic impact and imposes no 
additional burden on any person. Therefore, prior notice and public 
procedures hereon are unnecessary and the amendment may be made 
effective in less than 30 days after publication in the Federal 
Register.

Comments Invited

    Although this action is in the form of a final rule and was not 
preceded by notice and opportunity for public comment, comments are 
invited on this rule. Interested persons are invited to comment on this 
rule by submitting such written data, views, or arguments as they may 
desire. Communications shall identify the Rules Docket number and be 
submitted in triplicate to the address specified under the caption 
ADDRESSES. All communications received on or before the closing date 
for comments will be considered, and this rule may be amended in light 
of the comments received. Factual information that supports the 
commenter's ideas and suggestions is extremely helpful in evaluating 
the effectiveness of the AD action and determining whether additional 
rulemaking action would be needed.
    Submit comments using the following format:
     Organize comments issue-by-issue. For example, discuss a 
request to change the compliance time and a request to change the 
service bulletin reference as two separate issues.
     For each issue, state what specific change to the proposed 
AD is being requested.
     Include justification (e.g., reasons or data) for each 
request.
    Comments are specifically invited on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify the rule. All comments submitted will be 
available, both before and after the closing date for comments, in the 
Rules Docket for examination by interested persons. A report that 
summarizes each FAA-public contact concerned with the substance of this 
AD will be filed in the Rules Docket.

[[Page 17497]]

    Commenters wishing the FAA to acknowledge receipt of their comments 
submitted in response to this rule must submit a self-addressed, 
stamped postcard on which the following statement is made: ``Comments 
to Docket Number 2000-NM-316-AD.'' The postcard will be date stamped 
and returned to the commenter.

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.
