would require replacing the placards on
certain stowage bins with new placards,
installing partial dividers in certain
other stowage bins, and installing straps
on stowage bins containing life rafts. For
certain airplanes, this proposed AD
would also require related concurrent
actions. This proposed AD results from
test data indicating that outboard
overhead stowage bins are unable to
withstand the 4.5g down-load standard
intended to protect passengers during
flight turbulence or a hard landing. We
are proposing this AD to prevent the
stowage bins from opening during flight
turbulence or a hard landing, which
could result in the contents of the
stowage bins falling onto the passenger
seats below and injuring passengers, or
blocking the aisles, impeding the
evacuation of passengers in an
emergency.

Discussion
We have received test data from the
manufacturer indicating that the
outboard overhead stowage bins are
unable to withstand the 4.5g down-load
standard intended to protect passengers
during flight turbulence or a hard
landing. The affected airplanes are
certain Boeing Model 767–200 and –300
series airplanes. Under the 4.5g download condition, the threshold deflection
of the stowage bins is too large and
compromises the engagement of the
doors. This condition, if not corrected,
could result in the stowage bins opening
during flight turbulence or a hard
landing, which could result in the
contents of the stowage bins falling onto
the passenger seats below and injuring
passengers, or blocking the aisles,
impeding the evacuation of passengers
in an emergency.
Relevant Service Information
We have reviewed Boeing Special
Attention Service Bulletin 767–25–
0336, Revision 2, dated August 11,
2005. The service bulletin describes
procedures for replacing the placards on
certain stowage bins with new placards,
installing partial dividers in certain
other stowage bins, and installing straps
on stowage bins containing life rafts.
Although Revision 2 states that the
original issue of Service Bulletin 767–
25–0336 is dated September 18, 2003,
the date that appears on that document
is May 15, 2003.
For certain airplanes, Service Bulletin
767–25–0336, Revision 2, specifies prior
or concurrent accomplishment of
Boeing Service Bulletin 767–25–0211,
Revision 1, dated July 14, 1994. Service
Bulletin 767–25–0211, Revision 1,
describes procedures for replacing the
door latches, strikes, and thresholds on
the outboard overhead stowage
compartments with new, improved
latches, strikes, and thresholds.
Accomplishing the actions specified
in the service information is intended to
adequately address the unsafe
condition.
53107
FAA’s Determination and Requirements
of the Proposed AD
We have evaluated all pertinent
information and identified an unsafe
condition that is likely to exist or
develop on other airplanes of this same
type design. For this reason, we are
proposing this AD, which would require
accomplishing the actions specified in
the service information described
previously.
Clarification of Compliance Time for
the Modifications
Boeing Special Attention Service
Bulletin 767–25–0336, Revision 2,
specifies that it is not necessary to
modify all of the stowage bins at one
time, provided the modification of an
individual bin is completed prior to the
airplane returning to service. We agree
with this statement, but want to clarify
that the modification of all affected
stowage bins must be completed within
60 months after the effective date of the
proposed AD. In developing an
appropriate compliance time for this
AD, we considered not only the
manufacturer’s recommendation, but
the degree of urgency associated with
addressing the subject unsafe condition,
and the time necessary to perform the
modifications. We have determined that
a 60-month compliance time is an
appropriate interval of time for affected
airplanes to continue to operate without
compromising safety. We have
coordinated this compliance time with
Boeing.
Costs of Compliance
There are about 366 airplanes of the
affected design in the worldwide fleet.

estimated costs for U.S. operators to
comply with this proposed AD.

Federal Register / Vol. 70, No. 172 / Wednesday, September 7, 2005 / Proposed Rules
Authority: 49 U.S.C. 106(g), 40113, 44701.
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
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 proposed 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 proposed AD. See the ADDRESSES
section for a location to examine the
regulatory evaluation.
List of Subjects in 14 CFR Part 39

-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Boeing Model 767-200 and -300 series airplanes. This
proposed AD would require replacing the placards on certain stowage
bins with new placards, installing partial dividers in certain other
stowage bins, and installing straps on stowage bins containing life
rafts. For certain airplanes, this proposed AD would also require
related concurrent actions. This proposed AD results from test data
indicating that outboard overhead stowage bins are unable to withstand
the 4.5g down-load standard intended to protect passengers during
flight turbulence or a hard landing. We are proposing this AD to
prevent the stowage bins from opening during flight turbulence or a
hard landing, which could result in the contents of the stowage bins
falling onto the passenger seats below and injuring passengers, or
blocking the aisles, impeding the evacuation of passengers in an
emergency.
DATES: We must receive comments on this proposed AD by October 24,
2005.

Discussion
We have received test data from the manufacturer indicating that
the outboard overhead stowage bins are unable to withstand the 4.5g
down-load standard intended to protect passengers during flight
turbulence or a hard landing. The affected airplanes are certain Boeing
Model 767-200 and -300 series airplanes. Under the 4.5g down-load
condition, the threshold deflection of the stowage bins is too large
and compromises the engagement of the doors. This condition, if not
corrected, could result in the stowage bins opening during flight
turbulence or a hard landing, which could result in the contents of the
stowage bins falling onto the passenger seats below and injuring
passengers, or blocking the aisles, impeding the evacuation of
passengers in an emergency.
Relevant Service Information
We have reviewed Boeing Special Attention Service Bulletin 767-25-
0336, Revision 2, dated August 11, 2005. The service bulletin describes
procedures for replacing the placards on certain stowage bins with new
placards, installing partial dividers in certain other stowage bins,
and installing straps on stowage bins containing life rafts. Although
Revision 2 states that the original issue of Service Bulletin 767-25-
0336 is dated September 18, 2003, the date that appears on that
document is May 15, 2003.
For certain airplanes, Service Bulletin 767-25-0336, Revision 2,
specifies prior or concurrent accomplishment of Boeing Service Bulletin
767-25-0211, Revision 1, dated July 14, 1994. Service Bulletin 767-25-
0211, Revision 1, describes procedures for replacing the door latches,
strikes, and thresholds on the outboard overhead stowage compartments
with new, improved latches, strikes, and thresholds.
Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition.
FAA's Determination and Requirements of the Proposed AD
We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other airplanes
of this same type design. For this reason, we are proposing this AD,
which would require accomplishing the actions specified in the service
information described previously.
Clarification of Compliance Time for the Modifications
Boeing Special Attention Service Bulletin 767-25-0336, Revision 2,
specifies that it is not necessary to modify all of the stowage bins at
one time, provided the modification of an individual bin is completed
prior to the airplane returning to service. We agree with this
statement, but want to clarify that the modification of all affected
stowage bins must be completed within 60 months after the effective
date of the proposed AD. In developing an appropriate compliance time
for this AD, we considered not only the manufacturer's recommendation,
but the degree of urgency associated with addressing the subject unsafe
condition, and the time necessary to perform the modifications. We have
determined that a 60-month compliance time is an appropriate interval
of time for affected airplanes to continue to operate without
compromising safety. We have coordinated this compliance time with
Boeing.
Costs of Compliance
There are about 366 airplanes of the affected design in the
worldwide fleet. The following tables provide the estimated costs for
U.S. operators to comply with this proposed 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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
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 proposed AD. See the ADDRESSES section for a location
to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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]
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
Boeing: Docket No. FAA-2005-22321; Directorate Identifier 2005-NM-
123-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by October
24, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to certain Boeing Model 767-200 and -300
series airplanes, as identified in Boeing Special Attention Service
Bulletin 767-25-0336, Revision 2, dated August 11, 2005;
certificated in any category.
Unsafe Condition
(d) This AD results from test data indicating that outboard
overhead stowage bins are unable to withstand the 4.5g down-load
standard intended to protect passengers during flight turbulence or
a hard landing. We are issuing this AD to prevent the stowage bins
from opening during flight turbulence or a hard landing, which could
result in the contents of the stowage bins falling onto the
passenger seats below and injuring passengers, or blocking the
aisles, impeding the evacuation of passengers in an emergency.
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.
Replacement of Placards and Installation of Partial Divider Panels and
Life Raft Straps
(f) Within 60 months after the effective date of this AD:
Replace the placards on certain stowage bins with new placards,
install partial dividers in certain other stowage bins, and install
straps on stowage bins containing life rafts, in accordance with the
Accomplishment Instructions of Boeing Special Attention Service
Bulletin 767-25-0336, Revision 2, dated August 11, 2005.
Actions Required To Be Accomplished Prior to or Concurrently With
Paragraph (f) of This AD
(g) For Group 1 airplanes as identified in Boeing Special
Attention Service Bulletin 767-25-0336, Revision 2, dated August 11,
2005: Prior to or concurrently with the accomplishment of paragraph
(f) of this AD, replace the door latches, strikes, and thresholds on
the outboard overhead stowage compartments with new latches,
strikes, and thresholds. Do the replacement in accordance with the
Accomplishment Instructions of Boeing Service Bulletin 767-25-0211,
Revision 1, dated July 14, 1994.
Actions Accomplished Previously
(h) Accomplishment of the stowage bin modifications required by
paragraph (f) of this AD before the effective date of this AD in
accordance with Boeing Special Attention Service Bulletin 767-25-
0336, dated May 15, 2003; or Revision 1, dated October 21, 2004; is
considered acceptable for compliance with the corresponding
modifications specified in this AD.
Parts Installation
(i) As of the effective date of this AD, no person may install
on any airplane a stowage bin having a part number identified in
Table 2 of Figure 1 of Boeing Special Attention Service Bulletin
767-25-0336, Revision 2, dated August 11, 2005, unless it has been
modified by performing the applicable actions in paragraph (f) of
this AD.
Alternative Methods of Compliance (AMOCs)
(j) The Manager, Seattle Aircraft Certification Office, FAA, has
the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
Issued in Renton, Washington, on August 24, 2005.
Ali Bahrami,
Manager, Transport Airplane Directorate, Aircraft Certification
Service.
