[Docket No. 2000-NM-352-AD; Amendment 39-12214; AD 2001-09-09]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration, DOT.
 ACTION: Final rule; request for comments.
 SUMMARY: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires a one-time inspection to verify the proper configuration of the drive assemblies for the low-pressure and, for certain airplanes, the cross-feed fuel valves; and corrective action, if necessary. This action is necessary to prevent failure of the low-pressure and/or cross-feed fuel valves, which could result in the inability to shut off the fuel supply to the engine and exacerbate an engine fire, or the inability to cross-feed fuel when required. This action is intended to address the identified unsafe condition.
 DATES: Effective May 21, 2001. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of May 21, 2001. Comments for inclusion in the Rules Docket must be received on or before June 4, 2001.

SUPPLEMENTARY INFORMATION: The Direction Generale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, notified the FAA 
                    ( print page 22433)
                    that an unsafe condition may exist on certain Airbus Model A330 and A340 series airplanes. The DGAC advises that an operator of a Model A340 series airplane experienced an engine shutdown less than a minute after engine startup. Subsequent inspection of the low-pressure fuel valve drive of the engine revealed that a thrust washer was missing from the drive assembly. The reason for the missing washer is unknown. The absence of the washer allowed excessive movement of the spindle in the drive assembly, which caused the spindle to disconnect from the actuator. Because the actuator was not connected to the spindle of the drive assembly, the fuel valve could not be operated. Failure of the low-pressure fuel valve, if not corrected, could result in the inability to shut off the fuel supply to the engine and exacerbate an engine fire. The subject low-pressure fuel valves are installed on certain Model A330 and A340 series airplanes. Therefore, those Model A330 series airplanes are also subject to the unsafe condition identified in this AD. Failure of the cross-feed valves could result in the inability to cross-feed fuel when required only on Model A330 series airplanes flying under extended range twin-engine operations (ETOPS). Relevant Service Information Airbus has issued Service Bulletins A330-28A3069 (for Model A330 series airplanes) and A340-28A4087 (for Model A340 series airplanes), both dated July 27, 2000. The service bulletins describe procedures for a one-time inspection to verify the proper configuration of the drive assemblies for the low-pressure and cross-feed fuel valves. If the washer is missing, the service bulletins provide procedures for installing a new thrust washer. If excessive movement of the drive spindle is detected, the service bulletins provide procedures for inspecting the drive assembly to detect damage and wear and replacing unserviceable parts with serviceable parts. These actions are intended to adequately address the unsafe condition. The DGAC classified the service bulletins as mandatory and issued French airworthiness directives 2000-406-125(B) and 2000-405-152(B), both dated September 20, 2000, to ensure 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 § 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 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 low-pressure and/or cross-feed fuel valves, which could result in the inability to shut off the fuel supply to the engine and exacerbate an engine fire, or the inability to cross-feed fuel when required. This AD requires the actions specified in the service bulletins, 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 16 work hours to accomplish the required actions, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of this AD would be $960 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 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. 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 2000-NM-352-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 
                    ( print page 22434)
                    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
