ACTION: Final rule.
AGENCY:
rwilkins on PROD1PC63 with RULES
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to certain Bombardier
Model CL–600–2B19 (Regional Jet
Series 100 & 440) airplanes. The existing
AD currently requires inspecting
contactors 1K4XD, 2K4XD, and K4XA to
determine the type of terminal base
plate, and applying sealant on the
terminal base plates if necessary. This
AD requires an inspection to determine
if certain alternating current (AC)
service and utility bus contactors have
a terminal base plate made from non-G9
melamine material, and corrective
actions if necessary; or re-identification
of the mounting tray of the contactors;
as applicable. This AD also limits the
applicability of the existing AD. This
AD results from incidents of short
circuit failures of certain AC contactors
located in the avionics bay. We are
issuing this AD to prevent short circuit
failures of certain AC contactors, which
could result in arcing and consequent
smoke or fire.
DATES: This AD becomes effective April
8, 2008.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of April 8, 2008.
On August 9, 2006 (71 FR 45364,
August 9, 2006), the Director of the
Federal Register approved the
incorporation by reference of
Bombardier Service Bulletin 601R–24–

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that
supersedes AD 2006–17–14, amendment
39–14735 (71 FR 49337, August 23,
2006). The existing AD applies to
certain Bombardier Model CL–600–
2B19 (Regional Jet Series 100 & 440)
airplanes. That NPRM was published in
the Federal Register on November 21,
2007 (72 FR 65474). That NPRM
proposed to require inspecting
contactors 1K4XD, 2K4XD, and K4XA to
determine the type of terminal base
plate, and applying sealant on the
terminal base plates, if necessary. That
NPRM also proposed to require an
inspection to determine if certain
alternating current (AC) service and
utility bus contactors have a terminal
base plate made from non-G9 melamine
material, and corrective actions if
necessary; or re-identification of the
mounting tray of the contactors; as
applicable.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comment received from
one commenter.
Request To Give Credit for Actions
Already Done
The commenter, Larry Nelson,
requests that the phrase ‘‘unless already
accomplished’’ be added to paragraph
(h) of the NPRM after the compliance
time. The commenter notes that
Canadian airworthiness directive CF–
2006–17R1, dated May 30, 2007
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
11529
(referred to in the NPRM as related
information), states, ‘‘Within 12 months
from the effective date of this directive,
unless already accomplished.’’
We do not agree. A similar phrase is
already in paragraph (e) of this AD.
Paragraph (e) states, ‘‘You are
responsible for having the actions
required by this AD performed within
the compliance times specified, unless
the actions have already been done.’’
We have not changed the AD in this
regard.
Request To Allow Earlier Revisions of
Service Bulletin
The commenter, Larry Nelson,
requests that Bombardier Service
Bulletin 601R–24–123, dated November
13, 2006; or Revision A, dated December
7, 2006; be considered acceptable for
compliance with the actions specified in
paragraph (h) of the NPRM. The
commenter states that the technical
content in Bombardier Service Bulletin
601R–24–123, Revision B, dated
February 16, 2007 (referred to in the
NPRM as the appropriate source of
service information for doing the
proposed actions) did not change.
We do not agree. Bombardier Service
Bulletin 601R–24–123, Revision B,
includes additional actions (i.e., a
general visual inspection, reidentification, and applicable corrective
actions, as identified as Part C in the
service bulletin) beyond those in earlier
revisions of the service bulletin. Also,
Canadian airworthiness directive CF–
2006–17R1, which this AD parallels,
refers to Revision B or later revisions of
the service bulletin as the appropriate
source of service information for doing
the required actions. However, this AD
does not refer to ‘‘or later revisions’’ of
the service bulletin. Affected operators
may request approval to use a later
revision of the referenced service
bulletin as an alternative method of
compliance, under the provisions of
paragraph (j) of the AD. We have not
changed the AD in this regard.
Conclusion
We have carefully reviewed the
available data, including the comment
that has been received, and determined
that air safety and the public interest
require adopting the AD as proposed.

Authority for This Rulemaking
Adoption of the Amendment
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.
I
Regulatory Findings
rwilkins on PROD1PC63 with RULES
Number of
U.S.-registered
airplanes
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
this AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to all EMBRAER Model
EMB–135BJ, –135ER, –135KE, –135KL,
–135LR, –145, –145ER, –145MR,
–145LR, –145XR, –145MP, and –145EP
airplanes. That AD currently requires
reviewing the airplane maintenance
records for recent reports of vibration
from the tail section or rudder pedals.
The existing AD also currently requires
repetitively inspecting the skin,
attachment fittings, and control rods of
rudder II to detect cracking, loose parts,
wear, or damage; and related
investigative/corrective actions if
necessary. This new AD requires the
existing repetitive inspection to be done
with new service information. This new
AD also requires replacing the locking
tab washers on the control rods of the
rudder II and installing springs on the
hinge assemblies of the rudder II, which
would terminate the repetitive
inspection requirements. This AD
results from reports of rudder vibration
due to wear. We are issuing this AD to
prevent failure of multiple hinge
fittings, which could result in severe
vibration, and to prevent failure of the
rudder control rods, which could result
in jamming of the rudder II; and
possible structural failure and reduced
controllability of the airplane.
DATES: This AD becomes effective April
8, 2008.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of April 8, 2008.
On December 23, 2005 (70 FR 72902,

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that
supersedes AD 2005–25–04, amendment
39–14397 (70 FR 72902, December 8,

–145ER, –145MR, –145LR, –145XR,
–145MP, and –145EP airplanes. That
NPRM was published in the Federal
Register on December 17, 2007 (72 FR
71281). That NPRM proposed to
continue to require reviewing the
airplane maintenance records for recent
reports of vibration from the tail section
or rudder pedals. The NPRM also
proposed to continue to require
repetitively inspecting the skin,
attachment fittings, and control rods of
rudder II to detect cracking, loose parts,
wear, or damage; and related
investigative/corrective actions if
necessary. In addition to the existing
requirements, the NPRM proposed to
require that the existing repetitive
inspection be done with new service
information. The NPRM also proposed
to require replacing the locking tab
washers on the control rods of the
rudder II and installing springs on the

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to certain Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) airplanes. The existing AD currently requires
inspecting contactors 1K4XD, 2K4XD, and K4XA to determine the type of
terminal base plate, and applying sealant on the terminal base plates
if necessary. This AD requires an inspection to determine if certain
alternating current (AC) service and utility bus contactors have a
terminal base plate made from non-G9 melamine material, and corrective
actions if necessary; or re-identification of the mounting tray of the
contactors; as applicable. This AD also limits the applicability of the
existing AD. This AD results from incidents of short circuit failures
of certain AC contactors located in the avionics bay. We are issuing
this AD to prevent short circuit failures of certain AC contactors,
which could result in arcing and consequent smoke or fire.
DATES: This AD becomes effective April 8, 2008.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of April 8,
2008.
On August 9, 2006 (71 FR 45364, August 9, 2006), the Director of

Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comment received from one commenter.
Request To Give Credit for Actions Already Done
The commenter, Larry Nelson, requests that the phrase ``unless
already accomplished'' be added to paragraph (h) of the NPRM after the
compliance time. The commenter notes that Canadian airworthiness
directive CF-2006-17R1, dated May 30, 2007 (referred to in the NPRM as
related information), states, ``Within 12 months from the effective
date of this directive, unless already accomplished.''
We do not agree. A similar phrase is already in paragraph (e) of
this AD. Paragraph (e) states, ``You are responsible for having the
actions required by this AD performed within the compliance times
specified, unless the actions have already been done.'' We have not
changed the AD in this regard.
Request To Allow Earlier Revisions of Service Bulletin
The commenter, Larry Nelson, requests that Bombardier Service
Bulletin 601R-24-123, dated November 13, 2006; or Revision A, dated
December 7, 2006; be considered acceptable for compliance with the
actions specified in paragraph (h) of the NPRM. The commenter states
that the technical content in Bombardier Service Bulletin 601R-24-123,
Revision B, dated February 16, 2007 (referred to in the NPRM as the
appropriate source of service information for doing the proposed
actions) did not change.
We do not agree. Bombardier Service Bulletin 601R-24-123, Revision
B, includes additional actions (i.e., a general visual inspection, re-
identification, and applicable corrective actions, as identified as
Part C in the service bulletin) beyond those in earlier revisions of
the service bulletin. Also, Canadian airworthiness directive CF-2006-
17R1, which this AD parallels, refers to Revision B or later revisions
of the service bulletin as the appropriate source of service
information for doing the required actions. However, this AD does not
refer to ``or later revisions'' of the service bulletin. Affected
operators may request approval to use a later revision of the
referenced service bulletin as an alternative method of compliance,
under the provisions of paragraph (j) of the AD. We have not changed
the AD in this regard.
Conclusion
We have carefully reviewed the available data, including the
comment that has been received, and determined that air safety and the
public interest require adopting the AD as proposed.
Costs of Compliance
The following table provides the estimated costs for U.S. operators
to comply with 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 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 this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
