14 CFR Part 39
[Docket No. 2003-NM-75-AD; Amendment 39-13668; AD 2004-12-09]
RIN 2120-AA64
Airworthiness Directives; McDonnell Douglas Model MD-11 and -11F
Airplanes
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 airplanes,
that currently requires, among other actions, replacement of the
existing air driven generator (ADG) wire assembly in the right air
conditioning compartment with a certain new wire assembly. This
amendment requires replacement of the ADG wiring and two associated
clamps; inspection of the ADG wiring for correct wire identification,
riding, and damage, and inspection of the associated routing/clamps for
correct installation; and corrective actions if necessary. The actions
specified by this AD are intended to prevent loss of the charging
capability of the airplane battery due to chafing. Loss of the charging
capability of the airplane battery, coupled with a loss of all normal
electrical power, could prevent continued safe flight and landing of
the airplane. This action is intended to address the identified unsafe
condition.
DATES: Effective July 22, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of July 22, 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
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,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) by superseding AD 2001-17-12,
amendment 39-12403 (66 FR 44034, August 22, 2001), which is applicable
to certain McDonnell Douglas Model MD-11 and -11F airplanes, was
published in the Federal Register on April 1, 2004 (69 FR 17107). The
action proposed to require replacement of the air driven generator
(ADG) wiring and two associated clamps; inspection of the ADG wiring
for correct wire identification, riding, and damage, and inspection of
the associated routing/clamps for correct installation; and corrective
actions if necessary.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
Conclusion
The FAA has determined that air safety and the public interest
require the adoption of the rule as proposed.
Cost Impact
There are approximately 195 airplanes of the affected design in the
worldwide fleet. The FAA estimates that 81 airplanes of U.S. registry
will be affected by this AD. The following table shows the estimated
cost impact for airplanes affected by this AD. The average labor rate
is $65 per work hour.
Cost Estimate
------------------------------------------------------------------------
Per
For Airplanes identified in the Work Parts cost-- airplane
Service Bulletin as-- hours-- cost--
------------------------------------------------------------------------
Group 1........................ 2 $1,085 $1,215
Group 2........................ 1 (None) 65
Group 3........................ 1 (None) 65
------------------------------------------------------------------------
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
[[Page 33834]]
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 ``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
