SUPPLEMENTARY INFORMATION: The Direction Generale de l'Aviation Civile 
(DGAC), which is the airworthiness authority for France, notified the 
FAA that an unsafe condition may exist on certain Airbus Model A330-
243, -341, -342, and -343 series airplanes, which are equipped with 
Rolls-Royce engines. The DGAC advises that fatigue tests have revealed 
that the fail-safe link of the rear engine mount may not have adequate 
fatigue strength. The fail-safe link is intended to withstand 
operational loads in the event of loss of the primary load path for the 
engine. Failure of the fail-safe link of the rear engine mount, when 
combined with loss of the primary load path for the engine, could 
result in separation of the engine from the airplane.

Explanation of Relevant Service Information

    Airbus has issued Service Bulletin A330-71-3010, dated September 
25, 1999, which describes procedures for modifying the rear engine 
mount on the left- and right-hand sides of the airplane by replacing 
the existing fail-safe link with a new, improved fail-safe link. 
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 2001-544(B), dated November 14, 2001, in order 
to assure the continued airworthiness of these airplanes in France.
    Airbus Service Bulletin A330-71-3010 refers to Rolls-Royce Service 
Bulletin RB211-71-C639, dated September 10, 1999, as an additional 
source of service information for modification of the rear engine 
mount. The modification includes replacing the two-piece bearing with a 
one-piece bearing and increasing the thickness of the fail-safe link.

FAA's Conclusions

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
Sec. 21.29 of the Federal Aviation Regulations (14 CFR 21.19) 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 is 
being issued to prevent failure of the fail-safe link of the rear 
engine mount, which, in combination with failure of the primary load 
path for the engine, could result in separation of the engine from the 
airplane. This AD requires accomplishment of the actions specified in 
the Airbus service bulletin described previously.

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 40 work hours to 
accomplish the required actions, at an average labor rate of $60 per 
work hour. Required parts would be provided by the engine manufacturer 
at no charge to the operators. Based on these figures, the cost impact 
of this AD would be $2,400 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:
    <bullet> Organize comments issue-by-issue. For example, discuss a 
request to change the compliance time and a

[[Page 6376]]

request to change the service bulletin reference as two separate 
issues.
    <bullet> For each issue, state what specific change to the proposed 
AD is being requested.
    <bullet> 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.
    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 2001-NM-392-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.
