Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A310 series airplanes. This AD requires modifying the wire routing of electrical harness 636VB in the right-hand wing. This AD is prompted by the manufacturer's analysis for compliance with Special Federal Aviation Regulation No. 88, which has shown that wiring 2M of the 115V anti-collision white strobe lights and wiring 2S of the fuel quantity indication system (FQIS) should be rerouted into separate conduits. We are issuing this AD to prevent chafing damage to wiring 2M and 2S, which could result in a short circuit and consequently introduce an electrical current into the wiring of the FQIS and create an ignition source in the fuel tank.

DATES:

This AD becomes effective February 11, 2005.

The incorporation by reference of a certain publication listed in the AD is approved by the Director of the Federal Register as of February 11, 2005.

SUPPLEMENTARY INFORMATION:

The FAA proposed to amend 14 CFR part 39 with an AD for all Airbus Model A310 series airplanes. That action, published in the Federal Register on November 9, 2004 (69 FR 64871), proposed to require modifying the wire routing of electrical harness 636VB in the right-hand wing.

Comments

We provided the public the opportunity to participate in the development of this AD. No comments have been submitted on the proposed AD or on the determination of the cost to the public.

Conclusion

We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

This AD will affect about 51 airplanes of U.S. registry. The required actions will take about 34 work hours per airplane, at an average labor rate of $65 per work hour. Required parts will cost about $356 per airplane. Based on these figures, the estimated cost of the AD for U.S. operators is $130,866 or $2,566 per airplane.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.

We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Regulatory Findings

We have determined that this AD will not have federalism implications under Executive Order 13132. This AD 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.

For the reasons discussed above, I certify that this AD:

(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.

We prepared a regulatory evaluation of the estimated costs to comply with this AD. See the ADDRESSES section for a location to examine the regulatory evaluation.
