[Docket No. 2001-NM-54-AD; Amendment 39-13845; AD 2004-22-17]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration, DOT.
 ACTION: Final rule.
 SUMMARY: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 and MD-11F airplanes, that requires an inspection of the connector cables for signs of arcing and/or signs of moisture penetration into the overhead decoder units (ODU), and replacement of the affected ODU(s) with a new ODU, if necessary. This action also requires modification and reidentification of the cable assemblies and the connect cable assemblies at shipside power to the ODU, ODU to ODU, and adjacent bag racks; and replacing certain connectors of the ODU and shipside power cable assemblies. The actions specified by this AD are intended to prevent moisture from entering through the rear of the connector of the ODUs located in the overhead baggage stowage racks, which could result in a short, damage to the connector pins, and consequent smoke and/or fire in the cabin. This action is intended to address the identified unsafe condition.
 DATES: Effective December 14, 2004. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of December 14, 2004.
 ADDRESSES: The service information referenced in this AD may be obtained from Boeing Commercial Airplanes, Long Beach Division, 3855 Lakewood Boulevard, Long Beach, California 90846, Attention: Data and Service Management, Dept.

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 certain McDonnell Douglas Model MD-11 and MD-11F airplanes was published as a supplemental notice of proposed rulemaking (NPRM) in the 
                    **Federal Register**
                     on July 13, 2004 (69 FR 41987). That action proposed to require an inspection of the connector cables for signs of arcing and/or signs of moisture penetration into the overhead decoder units (ODU), and replacement of the affected ODU(s) with a new ODU, if necessary. That action also proposed to require modification and 
                    ( print page 64851)
                    reidentification of the cable assemblies and the connect cable assemblies at shipside power to the ODU, ODU to ODU, and adjacent bag racks; and replacing certain connectors of the ODU and shipside power cable assemblies. 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 114 airplanes of the affected design in the worldwide fleet. The FAA estimates that 28 airplanes of U.S. registry will be affected by this AD, that it will take approximately between 295 and 2,056 work hours per airplane (
                    *i.e.*, 2 work hours per ODU and shipside connector; the number of ODUs and shipside connectors per airplane will vary between 59 and 1,028 depending on the airplane's configuration) to accomplish the required actions, and that the average labor rate is $65 per work hour. Required parts will cost approximately between $2,264 and $130,864 per airplane (depending on the airplane configuration). Based on these figures, the cost impact of the AD on U.S. operators is estimated to be between $21,439 and $264,504 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. The manufacturer may cover the cost of replacement parts associated with this proposed AD, subject to warranty conditions. As a result, the costs attributable to the proposed AD may be less than stated above. 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
