The FAA proposed to amend 14 CFR part 39 with an AD for certain McDonnell Douglas Model MD-11 airplanes. That action, published in the Federal Register on July 13, 2004 (69 FR 41990), proposed to require revising the cable connection stackups for mid-cabin terminal strips, replacing the terminal strips, and removing a nameplate, as applicable. That action also proposed to require an inspection for arcing damage in the mid-cabin area, and corrective actions if necessary.

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.

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

This AD will affect about 23 airplanes of U.S. registry and 90 airplanes worldwide. The required actions will take between 5 and 6 work hours per airplane depending on the airplane configuration, at an average labor rate of $65 per work hour. Required parts will cost between $673 and $975 depending on the airplane configuration. The airplane configuration group requiring the fewest number of work hours requires parts that cost approximately $710. Based on these figures, the estimated cost of the AD for U.S. operators is between $1,035 and $1,365 per airplane depending on the airplane configuration.

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.

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

1. The authority citation for part 39 continues to read as follows:

2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):
