During post-delivery modifications of certain Boeing Model 767-200 and -300 series airplanes, the manufacturer found that the rudder cables and the First Officer's elevator control cables may come in contact with the video control center (VCC) wires, which could result in possible chafing and subsequent arcing of the wires in the wire bundles and severing of the cables. Severed cables, if combined with an engine-out during takeoff, or a high crosswind during takeoff or landing, could result in reduced controllability of the airplane. \n\nExplanation of Relevant Service Information \n\n\tWe have reviewed and approved the following Boeing alert service bulletins: \n\n\n\nService bulletin\nRevision level\nDate\nModel\n767-23A0147, including Appendix A\nOriginal\nApril 6, 2000\n767-300\n767-23A0154\nOriginal\nMarch 15, 2001\n767-300\n767-23A0155, including Appendix A\nOriginal\nMarch 29, 2001\n767-300\n767-23A0156, including Appendix A\nOriginal\nApril 19, 2001\n767-200, -300\n767-23A0157\nOriginal\nMay 3, 2001\n767-300\n\nThese service bulletins describe procedures for modification of the wire bundles of the VCC of the passenger address and entertainment system. The modification includes, but is not limited to, installation of a wiring shroud and associated hardware between the VCC master control unit wiring and the flight control cables; re-routing of the VCC wire bundles above the flight control pulley box; and replacement of existing clamps with new clamps; as applicable. Service bulletins 767-23A0154 and 767-23A0157 also describe procedures for an operational test after accomplishment of the modification. Accomplishment of the actions specified in the applicable service bulletin is intended to adequately address the identified unsafe condition. \n\nExplanation of Requirements of the Rule \n\n\tSince an unsafe condition has been identified that is likely to exist or develop on other airplanes of the same type design that may be registered inthe United States at some time in the future, this AD is being issued to prevent chafing of the wire bundles of the VCC against the rudder and/or elevator control cables, which could result in arcing of the wires in the wire bundles and severing of the cables. Severed cables, if combined with an engine-out during takeoff, or a high crosswind during takeoff or landing, could result in reduced controllability of the airplane. This AD requires modification of the wire bundles of the VCC of the passenger address and entertainment system. The actions are required to be accomplished in accordance with the applicable service bulletin described previously, except as discussed below. \n\nDifference Between the Service Bulletins and This AD \n\n\tAlthough the service bulletins recommend accomplishing the specified actions at the earliest maintenance opportunity when manpower and materials are available, we have determined that such an imprecise compliance time would not address the identified unsafe condition in a timely manner. In developing an appropriate compliance time for this AD, we considered not only the manufacturer's recommendation, but the degree of urgency associated with addressing the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the modification (2 work hours). In light of all of these factors, we find a 6-month compliance time for completing the required actions to be warranted, in that it represents an appropriate interval of time allowable for affected airplanes to continue to operate without compromising safety. \n\nChanges to 14 CFR Part 39/Effect on the AD \n\n\tOn July 10, 2002, the FAA issued a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs the FAA's airworthiness directives system. The regulation now includes material that relates to altered products, special flight permits, and alternative methods of compliance. Because we have now included this material in part 39,we no longer need to include it in each individual AD; however, this AD identifies the office authorized to approve alternative methods of compliance. \n\nRevised Labor Rate \n\n\tWe have reviewed the figures we have used over the past several years to calculate AD costs to operators. To account for various inflationary costs in the airline industry, we find it necessary to increase the labor rate used in these calculations from $60 per work hour to $65 per work hour. The cost impact information, below, has been revised to reflect this increase in the specified hourly labor rate. \n\nCost Impact \n\n\tNone of the airplanes affected by this action are on the U.S. Register. All airplanes included in the applicability of this rule currently are operated by non-U.S. operators under foreign registry; therefore, they are not directly affected by this AD action. However, the FAA considers that this rule is necessary to ensure that the unsafe condition is addressed in the event that any of these subject airplanes are imported and placed on the U.S. Register in the future.\n \n\tShould an affected airplane be imported and placed on the U.S. Register in the future, it would require approximately 2 work hours to accomplish the required modification, at an average labor rate of $65 per work hour. Parts cost would be between $64 and $915 per airplane. Based on these figures, the cost impact of the modification required by this AD would be between $194 and $1,045 per airplane. \n\nDetermination of Rule's Effective Date \n\n\tSince this AD action does not affect any airplane that is currently on the U.S. register, it has no adverse economic impact and imposes no additional burden on any person. Therefore, prior notice and public procedures hereon are unnecessary and the amendment may be made effective in less than 30 days after publication in the Federal Register. \n\nComments Invited \n\n\tAlthough this action is in the form of a final rule and was not preceded by notice and opportunity for public comment, comments are invited on this rule. Interested persons are invited to comment on this rule by submitting such written data, views, or arguments as they may desire. Communications shall identify the Rules Docket number and be submitted in triplicate to the address specified under the caption ADDRESSES. All communications received on or before the closing date for comments will be considered, and this rule may be amended in light of the comments received. Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed. \n\n\tSubmit comments using the following format: \n\nOrganize comments issue-by-issue. For example, discuss a request to change the compliance time and a request to change the service bulletin reference as two separate issues. \nFor each issue, state what specific change to the AD is being requested. \nInclude justification (e.g., reasons or data) for each request. \n\n\tComments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. All comments submitted will be available, both before and after the closing date for comments, in the Rules Docket for examination by interested persons. A report that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket. \n\n\tCommenters wishing the FAA to acknowledge receipt of their comments submitted in response to this rule must submit a self-addressed, stamped postcard on which the following statement is made: "Comments to Docket Number 2002-NM-205-AD." The postcard will be date stamped and returned to the commenter. \n\nRegulatory Impact \n\n\tThe 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. \n\n\tFor 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. \n\nList of Subjects in 14 CFR Part 39 \n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. \n\nAdoption of the Amendment \n\nAccordingly,pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n1.
