SUMMARY: This amendment supersedes an existing airworthiness directive
(AD), applicable to certain McDonnell Douglas Model MD-11 series
airplanes, that currently requires deactivation of the map light
assemblies; or modification and reidentification of the insulation
blankets adjacent to certain map light assemblies, if applicable, a
general visual inspection to detect damage of the Captain, First
Officer, and Right Observer map light assemblies, and follow-on
actions. This amendment is prompted by the FAA's determination that
certain airplanes equipped with reading light assemblies in the crew
rest area are subject to the identified unsafe condition. For certain
airplanes, this amendment requires deactivation of the reading light
assemblies, or an inspection to detect damage of the reading light
assemblies, and follow-on or corrective actions, as applicable. The
actions specified in this AD are intended to detect any broken light
bulb housing, which could expose the power contactor. An exposed power
contactor could cause the Captain, First Officer, or Right Observer map
light or reading light in the crew rest area to short or overheat,
which could result in smoke or fire in the cockpit.

SUPPLEMENTARY INFORMATION: On March 28, 2000, the FAA issued AD 2000-
07-02, amendment 39-11656 (65 FR 17763, April 5, 2000), applicable to
certain McDonnell Douglas Model MD-11 series airplanes, to require
deactivation of the map light assemblies; or modification and
reidentification of the insulation blankets adjacent to certain map
light assemblies, if applicable, a general visual inspection to detect
damage of the Captain, First Officer, and Right Observer map light
assemblies, and follow-on actions. That action was prompted by
incidents in which a broken or cracked light bulb housing of the First
Officer map light was found. The actions required by that AD are
intended to detect a broken light bulb housing, which could expose the
power contactor. An exposed power contactor
[[Page 3]]
could cause the Captain, First Officer, or Right Observer map light to
short or overheat, which could result in smoke or fire in the cockpit.
The incidents that prompted AD 2000-07-02 are 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
Since the issuance of AD 2000-07-02, an investigation revealed that
certain affected airplanes are equipped with Skybunk reading light
assemblies in the crew rest area. Skybunk reading light assemblies are
identical in design to the subject map light assemblies. An exposed
power contactor due to a broken or cracked light bulb housing could
cause the Captain, First Officer, or Right Observer map light or
reading light in the crew rest area to short or overheat, which could
result in smoke or fire in the cockpit or crew rest area.
Explanation of Relevant Service Bulletin
The FAA has review and approved Boeing Alert Service Bulletin MD11-
33A069,
Revision 01, including Appendix, dated November 30, 2000. The
procedures for deactivation of the map light assemblies; modification
and reidentification of the insulation blankets adjacent to certain map
light assemblies; a general visual inspection to detect damage of the
Captain, First Officer, and Right Observer map light assemblies; and
follow-on actions in Revision 01 of the service bulletin are identical
to those described in the original issue of the service bulletin (which
was referenced in AD 2000-07-02 as the appropriate source of service
information). Revision 01 of the service bulletin also describes new
procedures for:
1. Deactivating the reading light assemblies in the crew rest area,
which includes disconnecting, coiling, and stowing the power wires to
each reading light assembly; ensuring that deactivated reading lights
do not illuminate; and installing an inop ring on the circuit breaker;
OR
2. Performing an inspection to detect damage (i.e., cracks, damaged
or broken components, or chafed or damaged reading light assembly
wires) of the reading light assemblies in the crew rest area, and
follow-on or corrective actions, as applicable. The follow-on actions
include ensuring that the operative reading lights illuminate, and
performing repetitive inspections of the reading light assemblies. The
corrective actions include replacing the reading light assembly with a
new or serviceable light assembly, ensuring that the deactivated
reading lights do not illuminate, and repetitive inspections of the
reading light assemblies; or deactivating the damaged reading light
assemblies.
Operators should note that Revision 01 of the service bulletin
incorrectly contains in ``Option 2 (Deactivate Damaged Reading Light
Assemblies),'' paragraph F., page 22, of the Accomplishment
Instructions a sentence that reads ``Perform repetitive inspections of
reading lights for damage per Compliance paragraph.'' As indicated in
the following sentence in that paragraph, repetitive inspections of a
deactivated reading light are not required.
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 2000-07-02 to continue to require deactivation of the map
light assemblies; or modification and reidentification of the
insulation blankets adjacent to certain map light assemblies, if
applicable, a general visual inspection to detect damage of the
Captain, First Officer, and Right Observer map light assemblies, and
follow-on actions. This AD also requires accomplishment of the new
actions specified in Boeing Alert Service Bulletin MD11-33A069,
Revision 01, including Appendix, dated November 30, 2000, described
previously.
Interim Action
This is considered to be interim action. The manufacturer has
advised that it currently is developing a modification that will
positively address the unsafe condition addressed by this AD. Once
final action is identified, or once the modification is developed,
approved, and available, the FAA may consider additional 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.
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-194-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.
