Federal Register Abstract
The FAA is superseding an existing airworthiness directive (AD), which applies to certain McDonnell Douglas Model MD-11 series airplanes. That AD currently requires a revision of the airplane flight manual (AFM) to alert the flightcrew that both flight management computers (FMCs) must be installed and operational. That AD also requires an inspection to determine the serial number of the FMCs; and follow- on corrective actions, if necessary, which terminate the AFM revision. That AD also requires an inspection to verify if a certain modification is on the identification plates of the FMCs; and applicable follow-on and corrective actions. This new AD requires installation of upgraded FMC software, which would terminate the existing AD. This new AD also adds airplanes to the applicability, including adding Model MD-10-10F and MD-10-30F airplanes. This AD results from a report that the FMC does not acknowledge the pre-set glareshield control panel (GCP) altitude when profile (PROF) mode is engaged in descent mode. We are issuing this AD to prevent the un-commanded descent of an airplane below the selected level-off altitude, which could result in an unacceptable reduction in the separation between the airplane and nearby air traffic or terrain.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to certain McDonnell Douglas Model MD-11 series
airplanes. That AD currently requires a revision of the airplane flight
manual (AFM) to alert the flightcrew that both flight management
computers (FMCs) must be installed and operational. That AD also
requires an inspection to determine the serial number of the FMCs; and
follow-
[[Page 47708]]
on corrective actions, if necessary, which terminate the AFM revision.
That AD also requires an inspection to verify if a certain modification
is on the identification plates of the FMCs; and applicable follow-on
and corrective actions. This new AD requires installation of upgraded
FMC software, which would terminate the existing AD. This new AD also
adds airplanes to the applicability, including adding Model MD-10-10F
and MD-10-30F airplanes. This AD results from a report that the FMC
does not acknowledge the pre-set glareshield control panel (GCP)
altitude when profile (PROF) mode is engaged in descent mode. We are
issuing this AD to prevent the un-commanded descent of an airplane
below the selected level-off altitude, which could result in an
unacceptable reduction in the separation between the airplane and
nearby air traffic or terrain.
DATES: This AD becomes effective September 22, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of September 22,
2006.
On November 26, 2001 (66 FR 53335, October 22, 2001), the Director
of the Federal Register approved the incorporation by reference of
McDonnell Douglas Service Bulletin MD11-34-085, Revision 01, dated
September 20, 1999.

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that supersedes AD 2001-21-05, amendment
39-12476 (66 FR 53335, October 22, 2001). The existing AD applies to
certain McDonnell Douglas Model MD-11 series airplanes. That NPRM was
published in the Federal Register on February 15, 2006 (71 FR 7880).
That NPRM proposed to retain all requirements of AD 2001-21-05 and
require installation of upgraded flight management computer (FMC)
software, which would terminate the existing AD. That NPRM also
proposed to add airplanes to the applicability, including adding Model
MD-10-10F and MD-10-30F airplanes.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments that have been
received on the NPRM.
Support for NPRM
The Air Line Pilots Association supports the NPRM.
Request To Supersede AD 2001-21-05 and AD 2004-18-04
UPS requests that the NPRM be rewritten to supersede both AD 2001-
21-05 and AD 2004-18-04, amendment 39-13782 (69 FR 53794, September 21,
2004), and allow compliance by installing FMCs part number (P/N)
4059050-921 in accordance with Boeing Service Bulletin MD11-34-129,
dated September 22, 2004.
We acknowledge the commenter's request; however we do not agree
that this AD should supersede both ADs. This AD is a supersedure of AD
2001-21-05 and does allow compliance by installing FMC P/N 4059050-921.
As specified in paragraphs (j)(2), (j)(3), and (j)(4) of this AD,
operators that install FMC P/N 4059050-921 must do so in accordance
with Boeing Service Bulletin MD11-34-129, dated September 22, 2004, and
as specified in paragraph (j) of this AD, doing the installation is
terminating action for the requirements of paragraphs (f) through (i)
of this AD (paragraphs (f) through (i) are a restatement of the
requirements of AD 2001-21-05).
This AD does not supersede AD 2004-18-04 because that AD contains
requirements for airplanes that are not in the applicability of this
AD. AD 2004-18-04 is applicable to all McDonnell Douglas Model MD-10-
10F, MD-10-30F, MD-11, MD-11F, and 717-200 airplanes. This AD is
applicable only to certain Model MD-10-10F and MD-10-30F airplanes and
all Model MD-11 and MD-11F airplanes. However, as specified in
paragraph (n)(4) of this AD, doing the applicable software/hardware
upgrades required by paragraph (j) or (k) of this AD is approved as an
alternative method of compliance for the actions required by AD 2004-
18-04. We have not revised this AD in this regard.
Request To Clarify That Airplanes Having FMC P/N 4059050-921 Installed
Are Not Applicable to the NPRM
The same commenter requests that the NPRM be clarified to indicate
that it is not effective for any airplanes that already have P/N
4059050-921 installed.
We disagree with the commenter that this AD is not applicable to
airplanes that already have P/N 4059050-921 installed. This AD is
applicable to all Model MD-11 and MD-11F airplanes and certain Model
MD-10-10F and MD-10-30F airplanes and requires installation of upgraded
FMC software. For Model MD-11 and MD-11F airplanes, installing P/N
4059050-921 is an acceptable method of compliance with paragraph (j) of
this AD. As specified in paragraph (e) of this AD, if the actions have
already been done, then operators are in compliance with the applicable
requirements of this AD. We have not revised this AD in this regard.
Request To Clarify That Any FMC P/N 4059050-921 Is Acceptable
Regardless of Origin
The same commenter requests that the NPRM be clarified to specify
that any FMC P/N 4059050-921 is acceptable for compliance with the NPRM
regardless of the origin of the part (original manufacture, factory
conversion, or on-aircraft conversion).
We agree with the commenter that any FMC P/N 4059050-921 is
acceptable for compliance. Paragraphs (j)(2), (j)(3), and (j)(4) of
this AD specify installing FMC P/N 4059050-921 in accordance with the
service information specified in those paragraphs. Any FMC P/N 4059050-
921 regardless of its origin is acceptable provided it is installed in
accordance with the service information. No change is necessary. If
operators install P/N 4059050-921 in accordance with a method that is
not specified in the service information identified in this AD,
operators must
[[Page 47709]]
request approval of an alternate of method of compliance as specified
in paragraph (n) of this AD.
Clarification of Service Bulletin Date
In the NPRM, we inadvertently referred to the date of Boeing
Service Bulletin MD11-34-068, Revision 3, as April 6, 2004. The correct
date is April 6, 2005. We have revised this AD accordingly.
Conclusion
We have carefully reviewed the available data, including the
comments that have been submitted, and determined that air safety and
the public interest require adopting the AD with the change described
previously. We have determined that this change will neither increase
the economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
There are about 230 airplanes of the affected design in the
worldwide fleet and about 117 U.S.-registered airplanes. The following
table provides the estimated costs for U.S. operators to comply with
this AD. The average labor rate per hour is $65.

Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD 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.
For the reasons discussed above, I certify that this AD:
(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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
