SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Boeing Model 747–400 and 747–400D
series airplanes. For certain airplanes,
this AD requires modifying the stowage
bin ladder of zone E, installing new
intercostals, removing existing tie rods,
and installing new tie rods. For certain
other airplanes, this AD requires
modifying the lateral shear beam. This
AD results from a report indicating that
the overhead lateral shear beam aft of
main entry door number 5 reacts to
certain loads from the weight of the
center stowage bins of zone E and
additional loads. We are issuing this AD
to prevent detachment of the center
stowage bins of zone E at forward load

Discussion
We have received a report indicating
that a review, at Boeing, of the airplane
interior loads on certain Boeing Model
747–400 and 747–400D series airplanes
without a door 5 crew rest, showed that
the overhead lateral shear beam aft of
main entry door number 5 does not
meet the 9g forward loading

Relevant Service Information
We have reviewed Boeing Special
Attention Service Bulletin 747–53–
2498, dated December 19, 2006. For
certain airplanes, the service bulletin
describes procedures for modifying the
stowage bin ladder of zone E by
installing new tie rod fittings, installing
new right and left intercostals, and
removing existing tie rods. For certain
other airplanes, the service bulletin
describes procedures for modifying the
lateral shear beam by installing
additional stiffeners. Accomplishing the
actions specified in the service
information is intended to adequately
address the unsafe condition.

SUPPLEMENTARY INFORMATION:
Background
We previously issued AD 2001–18–
04, amendment 39–12430 (66 FR 46512,
September 6, 2001), applicable to
certain Boeing Model 747–400 series
airplanes. That AD requires repetitive
inspections to detect damage or
deflection of the crew rest heat
exchanger (forward heat exchanger
only), and follow-on actions if
necessary. That AD also requires a onetime inspection to determine the part
number and shop code of the shell of
the crew rest area heat exchanger
(forward heat exchanger only), and
follow-on actions if necessary, which
terminate the repetitive inspections.
Discussion
Since issuance of AD 2001–18–04, we
have received a report of uncommanded
up and down pitch movement of an
airplane in flight and resistance in the
elevator controls on the ground during
taxi on a Boeing Model 747–400 series
airplane. An inspection revealed that
the rear heat exchanger shell of the air
distribution system of the crew rest area
had expanded and deformed inboard
and downwards, contacting the elevator
control cables, which restricted their
movements. Another inspection
revealed that the thickness of certain
forward heat exchanger shells of the air
distribution system of the crew rest area,
including forward heater exchanger
shell subject to the requirements of AD
2001–18–04, was incorrect. The
incorrect shells were manufactured from
two-ply laminate instead of three-ply
laminate.
Cracking and buckling of the forward
or rear heat exchanger shell of the air
distribution system of the crew rest area,
if not corrected, could result in jamming
of the rudder and/or elevator control
cables and consequent reduced
controllability of the airplane.
Relevant Service Information
Boeing has issued Service Bulletin
747–21A2439, Revision 2, dated May
24, 2007. The service bulletin describes
the following procedures:
• Repetitive general visual
inspections of the forward and rear heat
exchanger shells of the air distribution
system of the crew rest area for
discrepancies (i.e., cracks, creases,
deformation, deflection, and
interference with the rudder and/or

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Boeing Model 747-400 and 747-400D series airplanes. For certain
airplanes, this AD requires modifying the stowage bin ladder of zone E,
installing new intercostals, removing existing tie rods, and installing
new tie rods. For certain other airplanes, this AD requires modifying
the lateral shear beam. This AD results from a report indicating that
the overhead lateral shear beam aft of main entry door number 5 reacts
to certain loads from the weight of the center stowage bins of zone E
and additional loads. We are issuing this AD to prevent detachment of
the center stowage bins of zone E at forward load levels less than 9g
during an emergency landing, which could cause injury to passengers
and/or crew and could impede subsequent rapid evacuation.
DATES: This AD is effective December 26, 2007.

SUPPLEMENTARY INFORMATION:
Discussion
We have received a report indicating that a review, at Boeing, of
the airplane interior loads on certain Boeing Model 747-400 and 747-
400D series airplanes without a door 5 crew rest, showed that the
overhead lateral shear beam aft of main entry door number 5 does not
meet the 9g forward loading requirement. As a result, the overhead
lateral shear beam at that door reacts to loads from the weight of the
center stowage bins of zone E and to additional loads due to galleys,
life raft boxes, closets, and partitions (depending on airplane
configuration). This condition, if not corrected, could result in
detachment of the center stowage bins of zone E at forward load levels
less than 9g during an emergency landing, which could cause injury to
passengers and/or crew and could impede subsequent rapid evacuation.
Relevant Service Information
We have reviewed Boeing Special Attention Service Bulletin 747-53-
2498, dated December 19, 2006. For certain airplanes, the service
bulletin describes procedures for modifying the stowage bin ladder of
zone E by installing new tie rod fittings, installing new right and
left intercostals, and removing existing tie rods. For certain other
airplanes, the service bulletin describes procedures for modifying the
lateral shear beam by installing additional stiffeners. Accomplishing
the actions specified in the service information is intended to
adequately address the unsafe condition.
FAA's Determination and Requirements of This AD
No airplanes affected by this AD are on the U.S. Register. We are
issuing this AD because the unsafe condition described previously is
likely to exist or develop on other products of the(se) same type
design(s) that could be registered in the United States in the future.
This AD requires modifying the stowage bin ladder of zone E, installing
new intercostals, removing existing tie rods, and installing new tie
rods. For certain other airplanes, this AD requires modifying the
lateral shear beam.
Since no airplanes are affected by this AD, notice and opportunity
for public comment before issuing this AD are unnecessary.
Costs of Compliance
None of the airplanes affected by this action are on the U.S.
Register. All airplanes affected by this AD are currently operated by
non-U.S. operators under foreign registry; therefore, they are not
directly affected by this AD action. However, we consider this AD
necessary to ensure that the unsafe condition is addressed if any
affected airplane is imported and placed on the U.S. Register in the
future.
The following table provides the estimated costs for U.S. operators
to comply with this AD for any affected

FAA's Determination of the Effective Date
No airplane affected by this AD is currently on the U.S. Register.
Therefore, providing notice and opportunity for public comment is
unnecessary before this AD is issued, and this AD may be made effective
in less than 30 days after it is published in the Federal Register.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments before it becomes effective. However, we invite
you to send any written data, views, or arguments about this AD. Send
your comments to an address listed under the ADDRESSES section. Include
``Docket No. FAA-2007-0301; Directorate Identifier 2007-NM-069-AD'' at
the beginning of your comments. We specifically invite comments on the
overall regulatory, economic, environmental, and energy aspects of this
AD. We will consider all comments received by the closing date and may
amend this AD because of those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
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 the regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2007-25-18 Boeing: Amendment 39-15300. Docket No. FAA-2007-0301;
Directorate Identifier 2007-NM-069-AD.
Effective Date

airplanes, certificated in any category; as identified in Boeing
Special Attention Service Bulletin 747-53-2498, dated December 19,
2006.
Unsafe Condition
(d) This AD results from a report indicating that the overhead
lateral shear beam aft of main entry door number 5 reacts to certain
loads. We are issuing this AD to prevent detachment of the center
stowage bins of zone E at forward load levels less than 9g during an
emergency landing, which could cause injury to passengers and/or
crew and could impede subsequent rapid evacuation.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Modification, Installation, and Replacement
(f) Within 36 months after the effective date of this AD, do the
applicable actions required by paragraphs (f)(1) and (f)(2) of this
AD by doing all the actions in accordance with the Accomplishment
Instructions of Boeing Special Attention Service Bulletin 747-53-
2498, dated December 19, 2006.
(1) For Group 1 airplanes, as identified in the service
bulletin: Modify the stowage bin ladder of zone E, install new right
