Airworthiness Directives; McDonnell Douglas Model DC-9-81, -82, -
83, and -87 Series Airplanes, and Model MD-88 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain McDonnell Douglas Model DC-9-81, -82, -83, 
and -87 series airplanes, and Model MD-88 airplanes, that currently 
requires an inspection to detect damage, burn marks, or discoloration 
at certain electrical plugs and receptacles of the sidewall lighting in 
the passenger cabin, and correction of discrepancies. That AD also 
requires modification of the electrical connectors, which terminates 
the inspection requirement. That action was prompted by reports of 
failures of the electrical connectors in the sidewall fluorescent 
lighting, which resulted in smoke or lighting interruption in the 
passenger cabin. This amendment expands the applicability of the 
existing AD to include additional airplanes. This amendment is intended 
to prevent failures of the electrical connectors, which could result in 
poor socket/pin contact, excessive heat, electrical arcing, and 
subsequently, connector burn-through and smoke and/or fire in the 
passenger cabin.

DATES: Effective October 4, 2001.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of October 4, 2001.

ADDRESSES: The service information referenced in this AD may be 
obtained from Boeing Commercial Aircraft Group, Long Beach Division, 
3855 Lakewood Boulevard, Long Beach, California 90846, Attention: Data 
and Service Management, Dept. C1-L5A (D800-0024). This information may 
be examined at the Federal Aviation Administration (FAA), Transport 
Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton, 
Washington; or at the FAA, Los Angeles Aircraft Certification Office, 
3960 Paramount Boulevard, Lakewood, California; or at the Office of the 
Federal Register, 800 North Capitol Street, NW., suite 700, Washington,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 95-19-09, 
amendment 39-9371 (60 FR 48639, September 20, 1995), which is 
applicable to certain McDonnell Douglas Model DC-9-81, -82, -83, and -
87 series airplanes, and Model MD-88 airplanes, was published in the 
Federal Register on June 5, 2001 (66 FR 30095). That action proposed to 
require an inspection to detect damage, burn marks, or discoloration at 
certain electrical plugs and receptacles of the sidewall lighting in 
the passenger cabin, and correction of discrepancies. That action also 
proposed to require modification of the electrical connectors, 
terminating the inspection requirement. That action also proposed to 
expand the applicability of the existing AD to include additional 
airplanes.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the three comments received.
    Two airplane operators state that they have previously accomplished 
the actions required by the proposed AD and, therefore, would not be 
affected by the proposed AD. A third operator states that it does not 
own or operate any of the equipment affected by the proposed AD and, 
therefore, has no comments to offer.

[[Page 45757]]

Conclusion

    After careful review of the available data, including the comments 
noted above, the FAA has determined that air safety and the public 
interest require the adoption of the rule as proposed.

Cost Impact

    There are approximately 970 Model DC-9-81, -82, -83, and -87 series 
airplanes, and Model MD-88 airplanes of the affected design in the 
worldwide fleet. The FAA estimates that 470 airplanes of U.S. registry 
will be affected by this AD, that it will take approximately between 24 
and 31 work hours per airplane to accomplish the required actions, and 
that the average labor rate is $60 per work hour. Required parts will 
cost approximately $1,199 per airplane. Based on these figures, the 
cost impact of the AD on U.S. operators is estimated to be between 
$1,240,330, and $1,437,730, or between $2,639, and $3,059 per airplane.
    The cost impact figures discussed above are 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.

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
