AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule.

SUMMARY:

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A300 B2 and B4 and A300-600 series airplanes, that currently requires wiring modifications to the engine and auxiliary power unit (APU) fire detection system. This amendment requires new wiring modifications for the engine and APU fire detection system. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent the fire warning from terminating prematurely, which could result in an unnoticed, uncontained engine/APU fire.

DATES:

Effective February 1, 2001.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of February 1, 2001.

ADDRESSES:

The service information referenced in this AD may be obtained from Airbus Industrie, 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 99-27-10, amendment 39-11491 (65 FR 204, January 4, 2000), which is applicable to certain Airbus Model A310 and A300-600 series airplanes, was published in the Federal Register on August 2, 2000 (65 FR 47356). The action proposed to require new wiring modifications to the engine and auxiliary power unit (APU) fire detection system.

Clarification of Model Designation

Since the issuance of the proposed AD, the FAA has changed the manner in which it identifies the airplane models referred to as “Airbus Model A300 and A300-600 series airplanes” to reflect the model designation specified on the type certificate data sheet. This final rule has been revised to show the appropriate model designations for those airplanes.

Comments

Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were submitted in response to the proposal or the FAA's determination of the cost to the public.

Conclusion

The FAA has determined that air safety and the public interest require the adoption of the rule as proposed.

Cost Impact

There are approximately 113 Model A300 B2 and B4 and A300-600 series airplanes of U.S. registry that will be affected by this AD.

The actions required by this AD will take approximately 26 work hours per airplane to accomplish, at an average labor rate of $60 per work hour. Required parts will cost approximately $484 per airplane. Based on these figures, the cost impact of the requirements of this AD on U.S. operators is estimated to be $230,972, or $2,044 per airplane.

The cost impact figure discussed above is 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.
