Airworthiness Directives; Airbus Model A319 and A320 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
SUMMARY: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A319 and A320 series airplanes, that currently requires repetitive inspections to detect cracking and delamination of the containers in which the off-wing emergency evacuation slides are stored, and corrective actions if necessary. That AD also requires eventual modifications of the slides, which terminates the requirement for repetitive inspections. This action removes the currently required repetitive inspections, and requires an additional modification of the off-wing emergency evacuation slides. The actions specified by this AD are intended to prevent the loss of the emergency evacuation slides during flight, which could result in damage to the fuselage, and to prevent incorrect inflation of the emergency evacuation slides, which could result in the emergency exits being unusable during an emergency evacuation. This action is intended to address the identified unsafe condition.
DATES: Effective April 30, 2004.
The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of April 30, 2004.
The incorporation by reference of a certain other publication was approved previously by the Director of the Federal Register as of February 1, 2000 (64 FR 72533, December 28, 1999).
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 99-26-22, amendment 39-11481 (64 FR 72533, December 28,1999), which is applicable to certain Airbus Model A319 and A320 series airplanes, was published in the Federal Register on January 5, 2004 (69 FR 291). The action proposed to require removing the currently required repetitive inspections, and would require an additional modification of the off- wing emergency evacuation slides.
Comment
Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the one comment received.
The commenter supports the proposed rule.
Conclusion
After careful review of the available data, including the comment noted above, we have determined that air safety and the public interest require the adoption of the rule as proposed.
Cost Impact
The modification per Airbus Service Bulletin A320-25-1156, Revision 02, is currently required by AD 99-26-22, which is applicable to approximately 121 airplanes of U.S. registry. This modification takes approximately 3 work hours per airplane to accomplish (not including time for gaining access and closing up), at an average labor rate of $65 per work hour. The cost of required parts is now approximately $679 per airplane. Based on these figures, the cost impact of this current requirement is estimated to be $105,754, or $874 per airplane.
The new requirements of this AD would affect approximately 435 airplanes of U.S. registry.
The new actions that are required in this AD action will take approximately 3 work hours per airplane to accomplish, at an average labor rate of $65 per work hour. Required parts will cost approximately $80 per airplane. Based on these figures, the cost impact of the new actions is estimated to be $119,625, or $275 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.
