Airworthiness Directives; McDonnell Douglas Model MD-11 Series 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain McDonnell Douglas Model MD-11 series 
airplanes, that currently requires a one-time inspection to verify 
correct wire terminations of certain circuit breakers in the cockpit 
overhead switch panel; and correction of incorrect wire termination. 
That AD also requires that operators submit a report of the inspection 
results to the FAA. That AD was prompted by incidents in which the 
wiring of circuit breakers on the overhead switch panel lighting were 
found to be terminated improperly during production of the airplane, 
which bypassed the circuit breaker protection. This amendment expands 
the applicability of the existing AD to include additional airplanes, 
and removes the reporting requirement. The actions specified in this AD 
are intended to prevent smoke and possible fire in the overhead switch 
panel lighting circuitry due to an overload condition, as a result of 
lack of circuit breaker protection.

DATES: Effective August 23, 2000.
    The incorporation by reference of McDonnell Douglas Alert Service 
Bulletin MD11-33A027, dated March 10, 1999, as listed in the 
regulations, was approved previously by the Director of the Federal 
Register as of May 7, 1999 (64 FR 19695, April 22, 1999).
    The incorporation by reference of certain other publications listed 
in the regulations is approved by the Director of the Federal Register 
as of August 23, 2000.
    Comments for inclusion in the Rules Docket must be received on or 
before October 10, 2000.

SUPPLEMENTARY INFORMATION: On April 13, 1999, the FAA issued AD 99-09-
04, amendment 39-11136 (64 FR 19695, April 22, 1999), applicable to 
certain McDonnell Douglas Model MD-11 series airplanes, to require a 
one-time inspection to verify correct wire terminations of certain 
circuit breakers in the cockpit overhead switch panel; and correction 
of incorrect wire termination. That AD also requires that operators 
submit a report of the inspection results to the FAA. That action was 
prompted by incidents in which the wiring of circuit breakers on the 
overhead switch panel lighting were found to be terminated improperly 
during production of the airplane, which bypassed the circuit breaker 
protection. The actions required by that AD are intended to prevent 
smoke and possible fire in the overhead switch panel lighting circuitry 
due to an overload condition, as a result of lack of circuit breaker 
protection.
    The incident that prompted AD 99-09-04 is not considered to be 
related to an accident that occurred off the coast of Nova Scotia 
involving a McDonnell Douglas Model MD-11 series airplane. The cause of 
that accident is still under investigation.

Other Related Rulemaking

    The FAA, in conjunction with Boeing and operators of Model MD-11 
series airplanes, is continuing to review all aspects of the service 
history of those airplanes to identify potential unsafe conditions and 
to take appropriate corrective actions. This AD is one of a series of 
actions identified during that process. The process is continuing and 
the FAA may consider additional rulemaking actions as further results 
of the review become available.

Actions Since Issuance of Previous Rule

    The applicability statement of AD 99-09-04 lists the manufacturer's 
fuselage numbers of the affected airplanes, which were provided by the 
airplane manufacturer and referenced in the effectivity listing of 
McDonnell Douglas Alert Service Bulletin MD11-33A027, dated March 10, 
1999 (which was referenced as the appropriate source of service 
information for accomplishment of the requirements of that AD). Since 
the issuance of that AD, the airplane manufacturer has informed the FAA 
that it inadvertently omitted manufacturer's fuselage numbers 0476 
through 0489 inclusive, and 0491 through 0509 inclusive, from the 
referenced service bulletin. The FAA has determined that airplanes 
having those manufacturer's fuselage numbers are subject to the 
identified unsafe condition in addition to those listed in the 
applicability of AD 99-09-04 (i.e., manufacturer's fuselage numbers 
0447 through 0464 inclusive, and 0466 through 0475 inclusive).
    The FAA has reviewed and approved McDonnell Douglas Alert Service 
Bulletin MD11-33A027, Revision 01, dated June 2, 1999, and Revision 02, 
dated June 12, 2000, which revise the effectivity listing of the 
original issue of the service bulletin by including additional 
manufacturer's fuselage numbers of affected airplanes. The inspection 
and corrective action are identical to those described in the original 
version of the service bulletin.

Explanation of Requirements of Rule

    Since an unsafe condition has been identified that is likely to 
exist or develop on other airplanes of this same type design, this AD 
supersedes AD 99-09-04 to continue to require a one-time inspection to 
verify correct wire terminations of certain circuit breakers in the 
cockpit overhead switch panel; and correction of incorrect wire 
termination. This AD also expands the applicability of the existing AD 
to include additional airplanes.

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.

Comments Invited

    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:
    <bullet> 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.
    <bullet> For each issue, state what specific change to the AD is 
being requested.
    <bullet> 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-218-AD.'' The postcard will be date stamped 
and returned to the commenter.

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.
    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.
