Airworthiness Directives; Airbus Model A300 B2 Series Airplanes; A300 B4 Series Airplanes; A300 B4-600, B4-600R, F4-600R, and C4-605R Variant F (Collectively Called A300-600) Series Airplanes; and A310 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
SUMMARY: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A300 series airplanes, that currently requires either a one-time ultrasonic inspection, or repetitive visual inspections and eventual ultrasonic inspection, to detect cracking of the longitudinal skin splice above the mid-passenger door panels, and corrective actions if necessary. This amendment requires repetitive ultrasonic inspections to detect cracking of certain skin lap joints in additional areas of the fuselage and repair if necessary. This amendment also expands the applicability of the existing AD to include additional airplanes. The actions specified by this AD are intended to detect and correct cracking of certain skin lap joints, which could result in reduced structural integrity and decompression of the airplane. This action is intended to address the identified unsafe condition.
DATES: Effective May 26, 2004.
The incorporation by reference of certain publications, as listed in the regulations, is approved by the Director of the Federal Register as of May 26, 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 February 22, 2000 (65 FR 5756, February 7, 2000).
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.
FOR FURTHER INFORMATION CONTACT: Anthony Jopling, Aerospace Engineer, International Branch, ANM-116, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 227-2190; fax (425) 227-1149.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) by superseding AD 2000-02-39, amendment 39-11557 (65 FR 5756, February 7, 2000), which is applicable to certain Airbus Model A300 series airplanes, was published in the Federal Register on December 18, 2003 (68 FR 70464). The action proposed to continue to require either a one-time ultrasonic inspection, or repetitive visual inspections and eventual ultrasonic inspection, to detect cracking of the longitudinal skin splice above the mid-passenger door panels, and corrective actions if necessary. The action also proposed to require repetitive ultrasonic inspections to detect cracking of certain skin lap joints in additional areas of the fuselage and repair if necessary. In addition, the action proposed to expand the applicability of the existing AD to include additional airplanes.
Comments
Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the comment received.
[[Page 21398]]
Request To Reference Latest Service Information
The commenter requests that the proposed AD be revised to reference Revision 03, dated February 25, 2003, of Airbus Service Bulletin A300- 53-6129 (for Model A300-600 series airplanes); and Revision 01, dated February 25, 2003, of Airbus Service Bulletin A310-53-2112 (for Model A310 series airplanes); for accomplishment of the applicable actions specified in the proposed AD. The commenter states that, because the repair kits have been identified with these latest revisions, adding them to the AD will eliminate requests for alternative methods of compliance in order to accomplish the latest kit installation.
The FAA concurs with the commenter's request. We have reviewed Airbus Service Bulletin A300-53-6129, Revision 03, dated February 25, 2003; and Airbus Service Bulletin A310-53-2112, Revision 01, dated February 25, 2003; and find them to be acceptable methods of compliance for accomplishment of the actions required by this AD. The final rule has been revised to require accomplishment of the applicable actions per either Revision 02 (which was referenced in the proposed AD as the applicable source of service information for the applicable actions) or Revision 03 of Airbus Service Bulletin A300-53-6129 (for Model A300-600 series airplanes); or the original issue (which was referenced in the proposed AD as the applicable source of service information for the applicable actions) or Revision 01 of Airbus Service Bulletin A310-53- 2112 (for Model A310 series airplanes).
Conclusion
After careful review of the available data, including the comment noted above, the FAA has determined that air safety and the public interest require the adoption of the rule with the changes previously described. The FAA has determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.
Cost Impact
There are approximately 128 airplanes of U.S. registry that will be affected by this AD.
The ultrasonic inspection that is currently required by AD 2000-02- 39 takes approximately 4 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 actions is estimated to be $260 per airplane.
The detailed inspection that is currently required by AD 2000-02-39 takes approximately 2 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 actions is estimated to be $130 per airplane.
The ultrasonic inspection required in this AD action will take approximately 1 work hour per airplane to accomplish, at an average labor rate of $65 per work hour. Based on these figures, the cost impact of this inspection on U.S. operators is estimated to be $8,320, or $65 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.
