BILLING CODE 4910–13–P
currently requires inspection of the
attachment of the shoulder restraint
harness to the mounting bracket on
certain observer and attendant seats to
determine if a C-clip is used in the
attachment, and corrective action, if
necessary. This proposed AD would
remove certain airplanes from the
applicability and add others. This
proposed AD results from the
determination that some airplanes had
been inadvertently included in or
excluded from the applicability of the
existing AD and that certain additional
new airplanes are now subject to the
identified unsafe condition. We are
proposing this AD to prevent
detachment of the shoulder restraint
harness of the attendant or observer seat
from its mounting bracket during
service, which could result in injury to
the occupant of the seat.
We must receive comments on
this proposed AD by July 24, 2006.

Discussion
On November 16, 2001, we issued AD
2001–24–02, amendment 39–12518 (66
FR 59681, November 30, 2001). That AD
applies to certain Boeing Model 707–
100 long body, –100B long body, –100B
short body, –E3A, –300, –300B, and
–300C series airplanes; Model 727–100
and –200 series airplanes; Model 737–

airplanes; Model 747–100B, 747–200B,
747–200C, 747–200F, 747–300, 747–
400, 747–400D, 747SR, and 747SP series
airplanes; Model 757–200 and 757–
200PF series airplanes; and Model 767–
200 and –300 series airplanes.
AD 2001–24–02 requires inspecting
the attachment of the shoulder restraint
harness to the mounting bracket on
certain observer and attendant seats to
determine if a C-clip is used in the
attachment, and corrective action, if
necessary. That AD resulted from
reports of the shoulder restraint harness
of the attendant and observer seat
detaching from the mounting bracket.
We issued that AD to prevent injury to
the occupant of the seat.
Actions Since Existing AD Was Issued
Since we issued AD 2001–24–02, we
have learned that the applicability must
be revised to add certain airplanes and
remove others.
service information for affected Model
727 and 737 series airplanes. Boeing has
since issued Service Bulletin 727–25–
0295, Revision 2, dated February 6,
2003, to clarify Figure 1 in the service
bulletin. Boeing has also issued Special
Attention Service Bulletin 737–25–
1412, Revision 2, dated September 18,
2003, and Revision 3, dated December 2,
2004. Revision 2 of the Special
Attention service bulletin adds
airplanes PW231 through PW252
inclusive; Revision 3 removes airplanes
PW001 through PW054 inclusive and
PW091 through PW094 inclusive; those
airplanes were inadvertently excluded
or included in previous versions of the
service bulletin. The service bulletin
procedures are unchanged from those
described in Revision 1.
Accomplishing the actions specified
in the service information is intended to
adequately address the unsafe
condition.
Relevant Service Information
FAA’s Determination and Requirements
of the Proposed AD
AD 2001–24–02 refers to Boeing
Service Bulletins 727–25–0295,
Revision 1, dated May 17, 2001, and
737–25–1412, Revision 1, dated May 17,
2001, as the appropriate sources of
We have evaluated all pertinent
information and identified an unsafe
condition that is likely to develop on
other airplanes of the same type design.
For this reason, we are proposing this
AD, which would supersede AD 2001–
24–02 and would retain the
requirements of the existing AD. This
proposed AD would also revise the
applicability to remove certain airplanes
and add others.
Changes to Existing AD
We have revised the applicability of
this AD to also identify model
designations as published in the most
recent type certificate data sheet for the
affected models.
We have revised this action to clarify
the appropriate procedure for notifying
the principal inspector before using any
approved AMOC on any airplane to
which the AMOC applies.
Costs of Compliance
Since we issued AD 2001–24–02, we
have increased the labor rate used in the
cost estimate calculations from $60 to
$80 per work hour. However, with
respect to the total cost impact for the
fleet, this increase in the hourly labor
rate would be offset by the decrease in
the number of affected airplanes in this
proposed AD.
The following table provides 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

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

of the estimated costs to comply with
this proposed AD and placed it in the
AD docket. See the ADDRESSES section

certain Bombardier Model DHC–8–100,
DHC–8–200, DHC–8–300, and DHC–8–
400 series airplanes. This proposed AD
would require inspecting the left and
right control column torque tube
assemblies to determine the type of
rivets installed and replacing incorrect
or indeterminate type rivets with the
correct type rivets. This proposed AD
results from a report that incorrect rivets
having lower than required strength
were installed on the control column
torque tube during production. We are
proposing this AD to prevent shear
failure of control column torque tube
rivets, which could cause unexpected
decoupling of the elevators and large
unwanted deflection of the free elevator,
and consequent reduced controllability
of the airplane.

Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede an existing airworthiness
directive (AD) that applies to certain Boeing airplanes. The existing
AD currently requires inspection of the attachment of the shoulder
restraint harness to the mounting bracket on certain observer and
attendant seats to determine if a C-clip is used in the attachment, and
corrective action, if necessary. This proposed AD would remove certain
airplanes from the applicability and add others. This proposed AD
results from the determination that some airplanes had been
inadvertently included in or excluded from the applicability of the
existing AD and that certain additional new airplanes are now subject
to the identified unsafe condition. We are proposing this AD to prevent
detachment of the shoulder restraint harness of the attendant or
observer seat from its mounting bracket during service, which could
result in injury to the occupant of the seat.
DATES: We must receive comments on this proposed AD by July 24, 2006.
ADDRESSES: Use one of the following addresses to submit comments on
this proposed AD.

Discussion
On November 16, 2001, we issued AD 2001-24-02, amendment 39-12518
(66 FR 59681, November 30, 2001). That AD applies to certain Boeing
Model 707-100 long body, -100B long body, -100B short body, -E3A, -300,
-300B, and -300C series airplanes; Model 727-100 and -200 series
airplanes; Model 737-
[[Page 33268]]
200, -200C, -300, -400, and -500 series airplanes; Model 747-100B, 747-
200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747SR, and 747SP
series airplanes; Model 757-200 and 757-200PF series airplanes; and
Model 767-200 and -300 series airplanes.
AD 2001-24-02 requires inspecting the attachment of the shoulder
restraint harness to the mounting bracket on certain observer and
attendant seats to determine if a C-clip is used in the attachment, and
corrective action, if necessary. That AD resulted from reports of the
shoulder restraint harness of the attendant and observer seat detaching
from the mounting bracket. We issued that AD to prevent injury to the
occupant of the seat.
Actions Since Existing AD Was Issued
Since we issued AD 2001-24-02, we have learned that the
applicability must be revised to add certain airplanes and remove
others.
Relevant Service Information
AD 2001-24-02 refers to Boeing Service Bulletins 727-25-0295,
Revision 1, dated May 17, 2001, and 737-25-1412, Revision 1, dated May
17, 2001, as the appropriate sources of service information for
affected Model 727 and 737 series airplanes. Boeing has since issued
Service Bulletin 727-25-0295, Revision 2, dated February 6, 2003, to
clarify Figure 1 in the service bulletin. Boeing has also issued
Special Attention Service Bulletin 737-25-1412, Revision 2, dated
September 18, 2003, and Revision 3, dated December 2, 2004. Revision 2
of the Special Attention service bulletin adds airplanes PW231 through
PW252 inclusive; Revision 3 removes airplanes PW001 through PW054
inclusive and PW091 through PW094 inclusive; those airplanes were
inadvertently excluded or included in previous versions of the service
bulletin. The service bulletin procedures are unchanged from those
described in Revision 1.
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 develop on other airplanes of the
same type design. For this reason, we are proposing this AD, which
would supersede AD 2001-24-02 and would retain the requirements of the
existing AD. This proposed AD would also revise the applicability to
remove certain airplanes and add others.
Changes to Existing AD
We have revised the applicability of this AD to also identify model
designations as published in the most recent type certificate data
sheet for the affected models.
We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.
Costs of Compliance
Since we issued AD 2001-24-02, we have increased the labor rate
used in the cost estimate calculations from $60 to $80 per work hour.
However, with respect to the total cost impact for the fleet, this
increase in the hourly labor rate would be offset by the decrease in
the number of affected airplanes in this proposed AD.
The following table provides 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 and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.
