AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Raytheon Aircraft Company
(Raytheon) Model B300 airplanes. This
proposed AD would require you to
modify the cabin passenger seats by
installing a modification kit on each
passenger seat, removing the existing
technical standard order (TSO) label,
and re-identifying each modified
passenger seat assembly with a new part
number. This proposed AD results from
the seats not meeting the ultimate load
requirements of 14 CFR part 23 during
structural testing of the seat with design
changes. We are issuing this proposed
AD to prevent the passenger seats from
failing during emergency landing
conditions when high inertial loadings
occur. Passenger seat failure may result
in occupant injury.
DATES: We must receive comments on
this proposed AD by July 14, 2006.
ADDRESSES: Use one of the following to
submit comments on this proposed AD:

dms.dot.gov and follow the instructions
for sending your comments
electronically.
• Government-wide rulemaking Web
site: Go to https://www.regulations.gov
and follow the instructions for sending

Discussion
While testing for a minor design
change of certain cabin seats that are
installed on Raytheon Model B300
airplanes through a TSO, ERDA, Inc.
(the seat manufacturer at that time)
found the cabin seats failed before
reaching the design load requirements.
These passenger seats did not meet the
design load requirements of 14 CFR part
PO 00000
Frm 00001
Fmt 4702
Sfmt 4702
23 and the associated TSO. ERDA, Inc.
investigated the original testing methods
used for the passenger seats and found
that the applied test loads used were
inaccurate because of faulty equipment.
When tested using the correct applied
loads, ERDA, Inc. found structural
deficiencies. The current manufacturer
and TSO authorization holder is
DeCrane Aircraft Seating Company, Inc.
The affected passenger seats are only
installed on Raytheon Model B300
airplanes.
If the passenger seats do not meet the
design load requirements of 14 CFR part
23 and the associated TSO, the
passenger seats could fail during
emergency landing conditions when
high inertial loadings occur. Passenger
seat failure could result in occupant
injury.
Relevant Service Information
Raytheon has issued Service Bulletin
SB 25–3640, Rev. 1, Issued: May 2005,
Revised: January 2006.
The service bulletin includes
procedures for:
• Installing a modification kit on each
passenger seat, part number (P/N) 130–
5108–0001 or P/N 130–5108–0002;
• Removing the existing TSO label;
and
• Re-identifying each modified
passenger seat assembly with the new P/
N.
FAA’s Determination and Requirements
of This Proposed AD
We are proposing this AD because we
evaluated all information and
determined that an unsafe condition is
likely to exist or develop on other
Raytheon Model B300 airplanes of the
same type design.
This proposed AD would require you
to incorporate the actions in the
previously-referenced service bulletin.
Costs of Compliance
We estimate that this proposed AD
could affect 292 airplanes in the U.S.
registry that have the affected cabin
seats installed for a total of 1,372 cabin
passenger seats.
We estimate the following costs to do
this proposed modification:

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 summary of the costs
to comply with this proposed AD (and
other information as included in the
Regulatory Evaluation) and placed it in
the AD Docket. You may get a copy of

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 AD.
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 this proposed AD:
Examining the Docket

AGENCY:
SUMMARY: The FAA is revising an earlier
proposed airworthiness directive (AD)
for certain Boeing Model 757–200,
–200CB, and –300 series airplanes. The
original NPRM would have required
repetitive detailed inspections for
proper functioning of the girt bar leaf
springs for the escape slides to ensure
VerDate Aug<31>2005
14:37 May 18, 2006
Jkt 208001
the leaf springs retain the sliders and
the required 0.37-inch minimum
engagement between the sliders and
floor fittings is achieved at passenger
doors 1, 2, and 4, and corrective actions
if necessary. The original NPRM
resulted from a report that the escape
slides failed to deploy correctly during
an operator’s tests of the escape slides.
This action revises the original NPRM
by stating that this proposed AD would
not include procedures from the
airplane maintenance manuals and
component maintenance manuals that
allow bending the girt bar retention
springs. We are proposing this
supplemental NPRM to prevent escape
slides from disengaging from the
airplane during deployment or in use,
which could result in injuries to
passengers or flightcrew.
DATES: We must receive comments on
this supplemental NPRM by June 13,
2006.

Discussion
While testing for a minor design change of certain cabin seats that
are installed on Raytheon Model B300 airplanes through a TSO, ERDA,
Inc. (the seat manufacturer at that time) found the cabin seats failed
before reaching the design load requirements. These passenger seats did
not meet the design load requirements of 14 CFR part 23 and the
associated TSO. ERDA, Inc. investigated the original testing methods
used for the passenger seats and found that the applied test loads used
were inaccurate because of faulty equipment. When tested using the
correct applied loads, ERDA, Inc. found structural deficiencies. The
current manufacturer and TSO authorization holder is DeCrane Aircraft
Seating Company, Inc. The affected passenger seats are only installed
on Raytheon Model B300 airplanes.
If the passenger seats do not meet the design load requirements of
14 CFR part 23 and the associated TSO, the passenger seats could fail
during emergency landing conditions when high inertial loadings occur.
Passenger seat failure could result in occupant injury.
Relevant Service Information
Raytheon has issued Service Bulletin SB 25-3640, Rev. 1, Issued:
May 2005, Revised: January 2006.
The service bulletin includes procedures for:
Installing a modification kit on each passenger seat, part
number (P/N) 130-5108-0001 or P/N 130-5108-0002;
Removing the existing TSO label; and
Re-identifying each modified passenger seat assembly with
the new P/N.
FAA's Determination and Requirements of This Proposed AD
We are proposing this AD because we evaluated all information and
determined that an unsafe condition is likely to exist or develop on
other Raytheon Model B300 airplanes of the same type design.
This proposed AD would require you to incorporate the actions in
the previously-referenced service bulletin.
Costs of Compliance
We estimate that this proposed AD could affect 292 airplanes in the
U.S. registry that have the affected cabin seats installed for a total
of 1,372 cabin passenger seats.
We estimate the following costs to do this proposed modification:

passenger seats
per airplane may
vary. We
estimate a total
of 1,372 seats
in the entire
fleet.

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 AD.
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 this proposed AD:
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 summary of the costs to comply with this proposed AD
(and other information as included in the Regulatory Evaluation) and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket FAA-2005-22103; Directorate Identifier 2005-CE-42-AD'' in
