Federal Aviation Administration, DOT.
Final rule; request for comments.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-9-82 (MD-82) and DC-9-83 (MD-83) series airplanes, and Start Printed Page 70784Model MD-88 airplanes. This action requires deactivating the left and right lower sidewall lights located in the passenger compartment. This action is necessary to prevent arcing and heat damage of the Luminator fluorescent lamp holders located outboard of the Passenger Service Unit panel, which could result in smoke and fire in the passenger compartment. This action is intended to address the identified unsafe condition.
Effective December 13, 2000.
The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of December 13, 2000.
Comments for inclusion in the Rules Docket must be received on or before January 29, 2001.

The FAA has received a report from an operator of one instance of fire in the passenger compartment on a Model DC-9-82 (MD-82) airplane while the airplane was parked at the gate. Findings from the investigation indicate the source of the fire was due to arcing of the Luminator fluorescent lamp holder. Test findings indicate that the possibility of arcing exists when a combination of Page ballasts and Luminator fluorescent lamp holders is installed on these airplanes. Such arcing is attributed to the output of the Page ballast when fluorescent lamps are installed improperly in worn or deteriorated Luminator fluorescent lamp holders. The subject components on affected Model DC-9-83 (MD-83) series airplanes and MD-88 airplanes are identical to those installed on the affected Model DC-9-82 (MD-82) series airplanes. Therefore, all of these models may be subject to the same unsafe condition.
Explanation of Relevant Service Information
The FAA has reviewed and approved Boeing Alert Service Bulletin MD80-33A115, dated August 10, 2000, which describes procedures for deactivating the left and right lower sidewall lights located outboard of the Passenger Service Unit panel.
Explanation of the Requirements of the Rule
Since an unsafe condition has been identified that is likely to exist or develop on other airplanes of the same type design, this AD is being issued to prevent arcing and heat damage of the fluorescent lamp holders by deactivating the left and right lower sidewall lights located in the passenger compartment. This AD requires accomplishment of the actions specified in the alert service bulletin described previously.
This is considered to be interim action until final action is identified, at which time the FAA may consider further rulemaking.
Determination of Rule's Effective Date
Since a situation exists that requires the immediate adoption of this regulation, it is found that notice and opportunity for prior public comment hereon are impracticable, and that good cause exists for making this amendment effective in less than 30 days.
Although this action is in the form of a final rule that involves requirements affecting flight safety and, thus, was not preceded by notice and an 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.
Submit comments using the following format:
- Organize 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.
- For each issue, state what specific change to the AD is being requested.
- Include justification (e.g., reasons or data) for each request.
Comments 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.
Commenters 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 2000-NM-356-AD.” The postcard will be date stamped and returned to the commenter.
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. Start Printed Page 70785
The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and that it is not a “significant regulatory action” under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket. A copy of it, if filed, may be obtained from the Rules Docket at the location provided under the caption ADDRESSES.Start List of Subjects

The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
Compliance: Required as indicated, unless accomplished previously.
To prevent arcing and heat damage of the Luminator fluorescent lamp holders located outboard of the Passenger Service Unit panel, which could result in smoke and fire in the passenger compartment, accomplish the following:
(a) Within 90 days after the effective date of this AD, deactivate the left and right lower sidewall lights located in the passenger compartment, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin MD80-33A115, dated August 10, 2000.

Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Los Angeles ACO.
Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Manager, Los Angeles ACO.
