# AGENCY:

Federal Aviation Administration, DOT. 

# ACTION:

Final rule. 

# SUMMARY:

This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300 B2 and B4 series airplanes; Model A300 B4-600, A300 B4-600R, A300 F4-600R series airplanes, and A300 C4-605R Variant F airplanes (collectively called A300-600); and Model A310 series airplanes. This amendment requires a detailed inspection of certain pulleys and control cables in the rear fuselage for corrosion and damage; and corrective action, if necessary. This action is necessary to detect and correct frayed or corroded control cables for the elevator and rudder, which could result in a ruptured control cable, and possible reduced controllability of the airplane. This action is intended to address the identified unsafe condition. 

# DATES:

Effective November 17, 2004. 

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of November 17, 2004.

# SUPPLEMENTARY INFORMATION:

                    A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an airworthiness directive (AD) that is applicable to all Airbus Model A300 B2 and A300 B4; Model A300 B4-600, B4-600R, C4-605R Variant F, and F4-600R (collectively called A300-600); and Model A310 series airplanes; was published in the                     **Federal Register**                     on May 7, 2004 (69 FR 25511). That action proposed to require a detailed inspection of certain pulleys and control cables in the rear fuselage for corrosion and damage; and corrective action, if necessary.                 

## Comments 

Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the single comment received. 

## Request To Give Credit for Actions Done Previously 

One commenter requests that we revise the proposed AD to give credit for actions done previously according to the original issue of Airbus Service Bulletin A300-27A0197, including Appendix 01, dated August 8, 2002. (The proposed AD refers to Airbus Service Bulletin A300-27A0197, Revision 01, including Appendix 01, dated February 26, 2003; as the appropriate source of service information for doing the proposed actions on Model A300 B2 and A300 B4 series airplanes.) The commenter notes that the Accomplishment Instructions in Revision 01 of the service bulletin are unchanged from those in the original issue of the service bulletin. 

We concur. We have reviewed the original issue of Airbus Service Bulletin A300-27A0197 and concur that the Accomplishment Instructions are the same as those in Revision 01. We have added a new paragraph (c) to this final rule (and re-identified subsequent paragraphs accordingly) to give credit for actions done per the original issue of Airbus Service Bulletin A300-27A0197. 

## Explanation of Additional Change 

We have revised the applicability statement of this final rule to identify model designations as published in the most recent type certificate data sheet for the affected models. 

## 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 described previously. The FAA has determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. 

## Interim Action 

We consider this AD interim action. If final action is later identified, we may consider further rulemaking then. 

## Cost Impact 

We estimate that 174 airplanes of U.S. registry will be affected by this AD, and that it will take approximately 1 work hour per airplane to accomplish the required inspection. The average labor rate is $65 per work hour. Based on these figures, the cost impact of this AD on U.S. operators is estimated to be $11,310, or $65 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.**
