AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes an existing airworthiness directive
(AD), applicable to certain McDonnell Douglas Model MD-11 and -11F
airplanes, that currently requires, among other actions, replacing the
ground support bracket(s); and rerouting the ground cables of the
galley external power and main external power, as applicable. This
amendment requires replacing ground support brackets with new brackets,
and replacing ground cables of the galley external power and main
external power with new cables; as applicable. This amendment also
requires an inspection to detect the
[[Page 41415]]
presence of a fillet seal at the ground brackets and to detect
excessive length and correct terminations of the ground cables of the
galley and main external power, as applicable; and corrective actions
if necessary. The actions specified by this AD are intended to prevent
arcing and heat damage to the attachment points of the main external
and galley power receptacle ground wire, insulation blankets outboard
and aft of the receptacle area, and adjacent power cables, which could
result in smoke and fire in the forward cargo compartment. This action
is intended to address the identified unsafe condition.
DATES: Effective August 13, 2004.
The incorporation by reference of a certain publication listed in
the regulations is approved by the Director of the Federal Register as
of August 13, 2004.
ADDRESSES: The service information referenced in this AD may be
obtained from Boeing Commercial Airplanes, Long Beach Division, 3855
Lakewood Boulevard, Long Beach, California 90846, Attention: Data and

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) by superseding AD 2002-14-11,
amendment 39-12811 (67 FR 47651, July 19, 2002), which is applicable to
certain McDonnell Douglas Model MD-11 and -11F airplanes, was published
in the Federal Register on January 9, 2004 (69 FR 1549). The action
proposed to require replacing ground support brackets with new
brackets, and replacing ground cables of the galley external power and
main external power with new cables; as applicable. The action also
proposed to require an inspection to detect the presence of a fillet
seal at the ground brackets and to detect excessive length and correct
terminations of the ground cables of the galley and main external
power, as applicable; and corrective actions if necessary.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comments received.
Request to Allow Previously Approved Alternative Method of Compliance
(AMOC)
One commenter requests that AMOCs approved previously per AD 2002-
14-11 be considered approved as an AMOC with this AD. The commenter
states that Boeing Service Bulletin MD11-24A138, Revision 1, was
approved as an AMOC for AD 2002-14-11.
We agree and have revised the ``Alternative Methods of Compliance''
section of the final rule accordingly.
Requests for Editorial Changes
One commenter requests, for clarification purposes, that paragraphs
(a)(1) and (a)(3) of Table 1 of the AD be revised to specify that the
required actions must be done per applicable figure of the service
bulletin.
We agree that clarification is necessary, but do not agree that the
final rule needs to be changed. As specified in paragraph (a) of the
AD, the actions specified in paragraphs (a)(1) through (a)(4) of Table
1 must be done ``in accordance with the Accomplishment Instructions of
Boeing Alert Service Bulletin MD11-24A138, Revision 2, dated July 11,
2003.'' Paragraph 3.A., Accomplishment Instructions, of the service
bulletin references figures in the service bulletin for more specific
instructions for accomplishing the replacements and inspections
required by this AD. However, it does not specify any applicable
corrective actions for the required inspections; the applicable
corrective actions are only specified in the figures of the service
bulletin. Therefore, for clarification purposes, we referenced the
applicable figure for accomplishing the applicable corrective actions
only in paragraphs (a)(2) and (a)(4) of Table 1 of the AD.
The same commenter also requests other minor editorial changes. We
agree and have revised the final rule accordingly.
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 with the changes previously
described. The FAA has determined that these changes will neither
increase the economic burden on any operator nor increase the scope of
the AD.
Cost Impact
There are approximately 154 airplanes of the affected design in the
worldwide fleet. The FAA estimates that 69 airplanes of U.S. registry
will be affected by this AD.
The new actions that are required in this AD action will take
approximately 1 work hour per airplane to accomplish, at an average
labor rate of $65 per work hour. Required parts will cost approximately
between $175 and $2,002 per airplane, depending on airplane
configuration. Based on these figures, the cost impact of the
requirements of this AD on U.S. operators is estimated to between $240
and $2,067 per airplane, depending on airplane configuration.
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. The manufacturer may cover the cost of
replacement parts associated with this AD, subject to warranty
conditions. Manufacturer warranty remedies may also be available for
labor costs associated with this AD. As a result, the costs
attributable to the AD may be less than stated above.
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
[[Page 41416]]
``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.
