The FAA has received information identifying an unsafe condition regarding certain Boeing Model 767-300 airplanes (specifically, certain Model 767-333 airplanes). The sidewall-mounted reading lights in the attendant crew rest compartment of those airplanes have been modified in accordance with Supplemental Type Certificate (STC) ST00973WI-D. A potential for contact between an occupant of the crew rest compartment and the sidewall-mounted reading lights exists. Sustained contact between the occupant and the reading lights could result in possible injury to the occupant. Additionally, inadvertent contact could also occur between various flammable materials (e.g., sheets, blankets, flightcrew clothing) and the sidewall-mounted reading lights. Such contact between the flammable materials and the reading lights could cause charring or melting of the heated material and consequent emission of toxic or noxious gases. \n\nExplanation of Relevant Service InformationThe FAA has reviewed and approved Boeing Service Bulletin 767-33-0093, dated December 20, 2001, which describes procedures for removing each sidewall-mounted reading light in the attendant crew rest compartment, installing cover plates in place of the existing reading lights, removing each reading light switch, and installing a new reading light in place of the existing light switch. Accomplishment of the actions specified in the 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 in the United States at some time in the future, this AD is being issued to prevent contact between the occupant of the attendant crew rest compartment and the sidewall-mounted reading lights, which could result in possible injury to the occupant; and to prevent contact of flammable materials with the sidewall-mounted reading lights, which could cause charring or melting of heated material and result in the emission of toxic or noxious gases. This AD requires accomplishment of the actions specified in the service bulletin described previously. \n\nDetermination of Compliance Time \n\n\tThe Boeing service bulletin specified by this AD does not recommend a compliance time. The FAA has determined that a compliance time of 60 days is appropriate. We based this compliance time not only on the degree of urgency associated with addressing the identified unsafe condition, but on the practical aspect of installing the required modification, which is estimated to take only 6 work hours. \n\nCost Impact \n\n\tNone of the Model 767-300 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 6 work hours to accomplish the required actions, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of this AD would be $1,440 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. \n\nFor each issue, state what specific change tothe AD is being requested. \n\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-31-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 ofthe Amendment \n\n\tAccordingly, 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\n\t1.
