AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to certain transport category airplanes. That AD
currently requires modification of the reinforced flight deck door.
This new AD expands the applicability of the existing AD and requires
other actions related to the reinforced flight deck door. These other
actions include modifying the door, inspecting and modifying wiring in
the area, and revising the maintenance program to require more frequent
testing of the decompression panels of the flight deck door. This AD is
prompted by reports of discrepancies with the reinforced flight deck
door. We are issuing this AD to prevent inadvertent release of the
decompression latch and consequent opening of the decompression panel
in the flight deck door, or penetration of the flight deck door by
smoke or shrapnel, any of which could result in injury to the airplane
flightcrew. This AD also requires finding and fixing wire chafing,
which could result in arcing, fire, and/or reduced controllability of
the airplane.
DATES: This AD becomes effective July 19, 2005.
The incorporation by reference of certain publications listed in
the AD is approved by the Director of the Federal Register as of July
19, 2005.
On July 25, 2003 (68 FR 41063, July 10, 2003), the Director of the
Federal Register approved the incorporation by reference of certain
other publications listed in the AD.
ADDRESSES: For service information identified in this AD, contact

telephone (562) 627-5224; fax (562) 627-5210.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) with an AD to supersede
AD 2003-14-04, amendment 39-13223 (68 FR 41063, July 10, 2003). The
existing AD applies to certain Boeing Model 737-200, 737-300, 737-400,
737-500, 737-600, 737-700, 737-800, 737-900, 757-200, and 757-300
series airplanes; and McDonnell Douglas Model DC-10-10F, DC-10-30, DC-
10-30F, DC-10-40, MD-10-30F, MD-11, and MD-11F airplanes. The proposed
AD was published in the Federal Register on September 3, 2004 (69 FR
53848), to continue to require modification of the reinforced flight
deck door. The proposed AD would also expand the applicability of the
existing AD and require other actions related to the reinforced flight
deck door. These other actions include modifying the door, inspecting
and modifying wiring in the area, and revising the maintenance program
to require more frequent testing of the decompression panels of the
flight deck door.
[[Page 34317]]
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments that have been
submitted on the proposed AD.
Support and Conditional Support for the Proposed AD
One commenter supports the intent and language of the proposed AD.
A second commenter supports the proposed AD, provided that an
adequate supply of parts is available for the modification to be
accomplished within the proposed 18-month compliance time.
C&D Aerospace has indicated that they will be able to supply an
adequate number of parts during the proposed compliance time. We have
not changed the AD in this regard.
Request To Omit Requirement To Reduce Test Intervals
One commenter does not support reducing the interval for the
repetitive functional test of the decompression panels of the flight
deck door, which would be required by paragraph (i) of the proposed AD.
(Paragraph (i) of the proposed AD would require revising the FAA-
approved maintenance inspection program to include the information in
C&D Aerospace Report CDRB22-69, Revision E, dated November 8, 2002.
Revision E of that report reduces the repetitive interval for
functional testing of the decompression panels of the flight deck
door.) The commenter states that the proposed AD does not state a
justification for a reduction in the testing intervals. The commenter
states that the current inspection interval is sufficient. The
commenter recommends that we gather and review more operational data
before we increase the testing interval.
We do not concur. Our decision to require incorporating Revision E
of C&D Aerospace Report CDRB22-69, and the increased testing frequency
specified in that document, is based on analysis by the manufacturer,
not on in-service findings. Testing of the decompression panels has
been required only for a short time, and few inspections have been
accomplished. For this reason, a lack of detected failures would not
justify maintaining the current inspection interval. We also note that
reinforced flight deck doors delivered after November 8, 2002 (the
issue/approval date of Revision E of C&D Aerospace Report CDRB22-69),
are already subject to the reduced repetitive testing interval. We have
not changed the final rule in this regard.
Request To Omit Requirement To Strengthen Smoke Screen
One commenter requests that we do not require strengthening the
smoke screen on the flight deck door's decompression panels. The
commenter states that this action is not cited in the proposed AD, and
no service bulletin has been issued to support the strengthening of the
smoke screen.
We do not agree. We find that it is necessary to require
strengthening of the smoke screen on the flight deck door's
decompression panels. This action is included in the modification
required by paragraph (j) of this AD. The rationale for this decision
is stated in the ``Actions Since Existing AD Was Issued'' section of
the proposed AD: ``* * * strengthening the smoke screens will allow the
smoke screens to close properly and prevent smoke from entering the
flight deck in the event of a fire in the airplane. Smoke in the flight
deck could hinder the flightcrew's ability to continue to fly the
airplane safely.'' The Relevant Service Information section of the
proposed AD specifies that procedures for modifying the smoke screens
are included in C&D Aerospace Service Bulletin B211200-52-02, Revision
2, dated September 29, 2003 (for certain McDonnell Douglas Model DC-10,
MD-10, and MD-11 airplanes), and in C&D Aerospace Service Bulletin
B251200-52-01, dated April 30, 2003 (for certain Model MD-11
airplanes). Table 3 of this AD references these service bulletins. We
have not changed this AD in this regard.
Request To Omit Requirement To Install Placard
One commenter requests that we omit from paragraph (j) of the
proposed AD the proposed requirement to install a placard. The
commenter points out that the service bulletins specified in Table 3 of
the proposed AD for Boeing Model 737 and 757 series airplanes include
instructions for installing placards to show that the service bulletin
has been done. The commenter states that it has contacted C&D Aerospace
and C&D Aerospace is unable to provide additional placards should the
original one be lost or need replacement. The commenter is concerned
that the proposed wording of the AD would require it to install and
maintain the placards to be in compliance with the proposed AD.
We agree that installing the placard is not necessary to address
the unsafe condition. We have revised paragraph (j) of this AD to state
that, where the service bulletins referenced in Table 3 of this AD
specify installing a placard to show that the service bulletin has been
accomplished, this AD does not require that action.
Request To Omit Requirement To Rework Wiring
One commenter does not support the proposed requirement in
paragraph (l)(1) that would require reworking the wiring for the flight
deck door. The commenter feels that the rework is not needed, even
though the door manufacturer has provided information to modify the
airplane. The commenter states that its established operational
procedures, including but not limited to a pre-flight operational check
of the flight deck door by the flightcrew, obviate the need for the
proposed wiring rework. Moreover, the commenter states that other
operational procedures make it unlikely that security would be
adversely affected if we were to omit the requirement to rework the
wiring.
We do not agree. As we stated in the proposed AD, we have
determined that an unsafe condition exists related to certain wiring in
the area of the flight deck door on affected airplanes. For an unsafe
condition such as this one, we can better ensure long-term continued
operational safety by requiring modifications or design changes to
remove the source of the problem, rather than by requiring repetitive
inspections or operational tests. Long-term inspections or tests may
not provide the degree of safety necessary for the transport airplane
fleet. This, coupled with a better understanding of the human factors
associated with numerous repetitive inspections/tests, has led us to
consider placing less emphasis on special procedures and more emphasis
on design improvements. The requirement in this AD to rework wiring in
the area of the flight deck door is consistent with these
considerations. We have not changed the AD in this regard.
Request for Credit for Accomplishment of Previous Service Bulletin
Revisions
One commenter requests that we give credit for actions required by
paragraph (j) of this AD that were accomplished in accordance with the
issues of the service bulletins listed in the table below. The
commenter states that the instructions for the modifications in these
previous revisions are similar to the instructions in the service
bulletins listed in Table 3 of the proposed AD.

(The pages of C&D Aerospace Service Bulletin B231001-52-02,
Revision 3, are each dated February 7, 2003. However, the Revision
Transmittal Sheet is dated March 7, 2003. Since Revision 2 of that
service bulletin is dated February 20, 2003, we have determined that
March 7, 2003, is the correct date for Revision 3 of the service
bulletin.)
We concur with the intent of the commenter's request. Actions
accomplished before the effective date of this AD in accordance with
the applicable service bulletin revisions identified by the commenter
are acceptable for compliance with the corresponding requirement of
paragraph (j) of this AD. However, after the effective date of this AD,
required actions must be accomplished in accordance with the applicable
service bulletin identified in Table 3 of this AD. We have added a new
paragraph (l) to this AD (and re-identified subsequent paragraphs
accordingly) and have added Table 4 to this AD to give credit for
actions accomplished before the effective date of this AD.
Request To Refer to Latest Service Bulletin Revision and Give Credit
for Prior Issues
One commenter requests that we revise paragraph (l)(1) of the
proposed AD (which is identified as paragraph (m)(1) of this AD) to
require C&D Aerospace Alert Service Bulletin B221001-52A05, Revision 3,
dated October 3, 2003. Paragraph (l)(1) of the proposed AD refers to
C&D Aerospace Alert Service Bulletin B221001-52A05, Revision 2, dated
June 19, 2003, as the appropriate source of service information for the
actions required by that paragraph. The commenter also requests that we
give credit for actions done in accordance with C&D Aerospace Alert
Service Bulletin B221001-52A05, dated April 17, 2003; Revision 1, dated
May 14, 2003; and Revision 2.
We concur with the intent of the commenter's request. The
procedures in C&D Aerospace Alert Service Bulletin B221001-52A05,
Revision 3, are similar to those in Revision 2 of that service
bulletin. We have revised paragraph (m)(1) of this AD to require the
rework of wiring be done in accordance with Revision 3 of the service
bulletin. We have also revised paragraph (m)(1) to give credit for
actions done before the effective date of this AD in accordance with
the original issue, Revision 1, or Revision 2 of that service bulletin.
However, only Revision 3 of the service bulletin is acceptable for
actions accomplished on or after the effective date of this AD.
Request To Correct Incorrect References
One commenter requests that we revise the proposed AD to correct
incorrect references. The commenter notes that the Costs of Compliance
section and Table 3 of the proposed AD refer to C&D Aerospace Service
Bulletin B251200-52-01, dated April 30, 2003, as an ``alert'' service
bulletin. The commenter points out that C&D Aerospace Service Bulletin
B251200-52-01 was not released as an alert service bulletin. We have
revised all references to this service bulletin in this AD to remove
``alert.''
The commenter also notes that Table 1 does not refer to the correct
supplemental type certificate (STC) that applies to Boeing Model 757
series airplanes. The commenter notes that the applicable STC number is
ST01334LA. We have revised Table 1 of this AD accordingly.
Request To Refer to Latest Service Bulletin Issue
One commenter requests that we revise Table 2 of the proposed AD to
refer to C&D Aerospace Service Bulletin B211200-52-02, Revision 2,
dated September 29, 2003, instead of Revision 1, dated June 3, 2003.
The commenter notes that Revision 2 is the latest issue of that service
bulletin.
We do not concur with this request. Table 2 of this AD restates the
applicability of AD 2003-14-04 to establish which airplanes are subject
to the actions required by paragraphs (f) and (g) of this AD.
(Paragraphs (f) and (g) restate the requirements of AD 2003-14-04.) C&D
Aerospace Service Bulletin B211200-52-02, Revision 1, was the issue
referenced in the applicability of AD 2003-14-04. We note that
paragraph (f)(3) of this AD, which requires accomplishment of certain
actions in C&D Aerospace Service Bulletin B211200-52-02, references
both Revisions 1 and 2 of that service bulletin. We have made no change
in this regard.
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 changes described
previously. We have determined that these changes will neither increase
the economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
There are about 3,423 airplanes of the affected design worldwide.
The following table provides the estimated costs for U.S. operators
to comply with the currently required actions that this AD will
continue to require, at an average labor rate of $65 per work hour.

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
[[Page 34320]]
this AD. See the ADDRESSES section for a location to examine the
regulatory evaluation.
