RIN 2120-AA64
Airworthiness Directives; McDonnell Douglas Model MD-11 and -11F
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain McDonnell Douglas Model MD-11 and -11F airplanes,
that requires an inspection of the auto throttle servo (ATS) assembly
and corrective actions if necessary. The actions specified by this AD
are intended to prevent electrical shorting of the brake coils of the
ATS, which could result in smoke in the cockpit and/or passenger cabin.
This action is intended to address the identified unsafe condition.
DATES: Effective December 14, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of December 14, 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; at the FAA, Los Angeles Aircraft Certification Office, 3960
Paramount Boulevard, Lakewood, California; or at the National Archives
and Records Administration (NARA). For information on the availability

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain McDonnell Douglas Model
MD-11 and -11F airplanes was published as a supplemental notice of
proposed rulemaking (NPRM) in the Federal Register on July 13, 2004 (69
FR 41985). That action proposed to require an inspection of the auto
throttle servo assembly and corrective actions if necessary.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been submitted on the proposed
AD or on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Cost Impact
There are about 195 McDonnell Douglas Model MD-11 and -11F
airplanes of the affected design in the worldwide fleet. We estimate
that 62 airplanes of U.S. registry will be affected by this AD, that it
will take about 1 work hour per airplane to accomplish the inspection,
and that the average labor rate is $65 per work hour. Based on these
figures, the cost impact of the inspection required by this AD on U.S.
operators is estimated to be $4,030, or $65 per airplane.
The cost impact figure discussed above is 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
