Federal Register / Vol. 77, No. 239 / Wednesday, December 12, 2012 / Rules and Regulations
We are superseding an
existing airworthiness directive (AD) for
certain Bombardier, Inc. Model CL–600–
2B19 (Regional Jet Series 100 & 440)
airplanes. That AD currently requires
revising the airworthiness limitations
section (AWL) of the Instructions for
Continued Airworthiness (ICA) of the
Canadair Regional Jet Maintenance
Requirements Manual (MRM) by
incorporating new procedures for
repetitive detailed and special detailed
inspections for cracking of the aft
pressure bulkhead. This new AD
requires revising the maintenance
program to incorporate a revised task
specified in a certain temporary
revision, which requires an improved
non-destructive inspection procedure;
and adds airplanes to the applicability.
This AD was prompted by multiple
reports of cracks on the forward face of
the rear pressure bulkhead (RPB) web.
We are issuing this AD to detect and
correct cracking in the RPB, which
could result in reduced structural
integrity and rapid decompression of
the airplane.
DATES: This AD becomes effective
January 16, 2013.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of January 16, 2013.
The Director of the Federal Register

SUMMARY:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on June 1, 2012 (77 FR 32439),
and proposed to supersede AD 2005–
23–01, Amendment 39–14359 (70 FR
69073, November 14, 2005). That NPRM
proposed to correct an unsafe condition

for the specified products. Transport
Canada Civil Aviation (TCCA)
Mandatory Continuing Airworthiness
Information (MCAI) states:
Cracks on the forward face of the Rear
Pressure Bulkhead (RPB) web have been
discovered on three CL–600–2B19 aeroplanes
in-service. This indicates that the existing
inspection requirements of Airworthiness
Limitation (AWL) task 53–61–153 mandated
by [TCCA] AD CF–2005–13R1 are not
adequate. Failure of the RPB could result in
rapid decompression of the aeroplane.
A Temporary Revision (TR) has been made
to Part 2 of the Maintenance Requirements
Manual (MRM) to revise the existing AWL
task by introducing an improved NonDestructive Inspection (NDI) procedure to
ensure that fatigue cracking of the RPB is
detected and corrected.
This [TCCA] directive mandates the
incorporation of a new NDI procedure for
AWL task number 53–61–153.

it is necessary to allow Canadair
Regional Jet Temporary Revision TR
2B–2109, dated October 13, 2005, to be
removed from the maintenance
requirements manual once a general
revision is done. Further, we have
determined that it is necessary to add a
paragraph similar to paragraph (h) of
this AD to allow removal of the
temporary revision specified in
paragraph (i) of this AD. Accordingly,
we have revised this final rule to add
new paragraph (k) to this AD to specify
that information. Subsequent
paragraphs have been reidentified.
Comments
We gave the public the opportunity to
participate in developing this AD. We
have considered the comments received.
Request To Revise Serial Numbers
Air Wisconsin requested that we
correct the serial numbers in paragraph
(c) or (g) of the NPRM (77 FR 32439,
June 1, 2012) for consistency.
We disagree with the request. The
serial numbers specified in paragraph
(g) of this AD are only those that were
part of the applicability of AD 2005–23–
01, Amendment 39–14359 (70 FR
69073, November 14, 2005). Paragraph
(c) of this AD lists all serial numbers
that are affected by this new AD.
Request To Remove Certain Paragraphs
of the NPRM (77 FR 32439, June 1,
2012)
Air Wisconsin requested that we
remove paragraphs (g) and (h) from the
NPRM (77 FR 32439, June 1, 2012)
because paragraph (i) of the NPRM
supersedes those paragraphs. Air
Wisconsin stated several examples of
how paragraphs (g) and (h) are
superseded by paragraph (i) of the
NPRM.
We disagree with the commenter’s
request to remove paragraphs (g) and (h)
from this final rule. We find it necessary
to restate those paragraphs in this final
rule to ensure the existing inspections
are done until the required maintenance
program revision specified in paragraph
(i) of this AD is accomplished. In
addition, if an airplane is imported into
the United States, it is necessary to
accomplish the requirements of
paragraph (g) of this AD before the
airplane may be operated in this
country.
However, we find that clarification of
paragraph (i) of this AD is necessary.
Once the maintenance program revision
is accomplished, the restated
requirements of paragraph (g) of this AD
are terminated. Therefore, we have
revised the last sentence of paragraph (i)
of this AD to specify that doing the
revision required by paragraph (i) of this
AD terminates the requirements of
paragraph (g) of this AD.
In addition, we have retained
paragraph (h) in this final rule because
Requests To Clarify Compliance Time
In regard to paragraph (i)(2) of the
NPRM (77 FR 32439, June 1, 2012), Air
Wisconsin requested we clarify that, if
the last inspection performed met the
requirements of AWL 53–61–153
specified in Bombardier TR 2B–2187,
dated June 22, 2011, to Appendix B—
Airworthiness Limitations, of Part 2 of
the Bombardier CL–600–2B19 MRM, the
next inspection cycle as specified in
that TR is acceptable provided that
interval is not greater than that specified
in Bombardier TR 2B–2187, dated June
22, 2011.
In addition, Comair requested that we
provide credit for paragraph (i) of the
NPRM (77 FR 32439, June 1, 2012) for
operators that performed previous
inspections using the special detailed
inspection option specified in AWL 53–
61–153 of the Canadair Regional Jet TR
2B–2109, dated October 13, 2005, to
Appendix B, ‘‘Airworthiness
Limitations,’’ of Part 2 of the Canadair
Regional Jet MRM. Comair stated that it
requested this credit so that operators
would not be subject to the initial
compliance time specified in paragraph
(i)(1) or (i)(2) of the NPRM (77 FR
32439, June 1, 2012).
We agree to clarify the inspection
compliance time. We agree that, if the
last special detailed inspection (not the
detailed visual inspection) performed
met the requirements of AWL 53–61–
153 specified in Bombardier TR 2B–
2187, dated June 22, 2011; or Canadair
Regional Jet TR 2B–2109, dated October

inspection option specified in Canadair
Regional Jet TR 2B–2109, dated October

Request To Approve Previous
Alternative Methods of Compliance
(AMOC)
Air Wisconsin requested that a
statement be added to paragraph (k) of
the NPRM (77 FR 32439, June 1, 2012)
approving use of existing AMOCs that
were approved previously in accordance
with AD 2005–23–01, Amendment 39–
14359 (70 FR 69073, November 14,
2005).
We agree to allow existing AMOCs
approved in accordance with AD 2005–
23–01, Amendment 39–14359 (70 FR
69073, November 14, 2005), as AMOCs
for the corresponding requirements of
paragraphs (g) and (h) of this AD only.
We have revised paragraph (l)(1) of this
AD (referred to as paragraph (k)(1) of the
NPRM (77 FR 32439, June 1, 2012))
accordingly.
Request To Remove Reference to a
Certain TR
Air Wisconsin requested that we
remove the reference to Canadair
Regional Jet TR 2B–2109, dated October
13, 2005, to Appendix B—
Airworthiness Limitations, of Part 2 of
the Bombardier CL–600–2B19 MRM
from paragraph (j) of the NPRM (77 FR
32439, June 1, 2012). Air Wisconsin
noted that Canadair Regional Jet TR 2B–
2109, dated October 13, 2005, conflicts
with Bombardier TR 2B–2187, dated
June 22, 2011, and stated that
Bombardier TR 2B–2187, dated June 22,
2011, specifically removed the ‘‘visual
inspection’’ option that was in Canadair
Regional Jet TR 2B–2109, dated October
13, 2005.
We agree with the request for the
reasons stated by the commenter. We
VerDate Mar<15>2010

have removed the reference to Canadair
Regional Jet TR 2B–2109, dated October
13, 2005, to Appendix B—
Airworthiness Limitations, of Part 2 of
the Bombardier CL–600–2B19 MRM,
from paragraph (j) of this AD. Paragraph
(i) of this AD requires that the
maintenance program be revised to
incorporate Bombardier TR 2B–2187,
dated June 22, 2011. Paragraph (i) of this
AD also specifies that once the revision
is done, the requirements of paragraph
(g) of this AD are terminated (paragraph
(g) of the AD incorporated Bombardier
TR 2B–2109, dated October 13, 2005).
Conclusion
We reviewed the available data,
including the comments received, and
determined that air safety and the
public interest require adopting the AD
with the changes described previously
and minor editorial changes. We have
determined that these changes:
• Are consistent with the intent that
was proposed in the NPRM (77 FR
32439, June 1, 2012) for correcting the
unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (77 FR 32439,
June 1, 2012).
Costs of Compliance
We estimate that this AD will affect
about 586 products of U.S. registry.
The actions that are required by AD
2005–23–01, Amendment 39–14359 (70
FR 69073, November 14, 2005), and
retained in this AD take about 2 workhours per product, at an average labor
rate of $85 per work hour. Based on
these figures, the estimated cost of the
currently required actions is $170 per
product.
We estimate that it will take about 1
work-hour per product to comply with
the new basic requirements of this AD.
The average labor rate is $85 per workhour. Based on these figures, we
estimate the cost of this AD to the U.S.
operators to be $49,810, or $85 per
product.
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
PO 00000
Frm 00008
Fmt 4700
Sfmt 4700
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 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 the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://

continued damage tolerance of the affected
structure. The FAA has provided guidance
for this determination in FAA Advisory
Circular (AC) 25.1529–1A, dated November
20, 2007 (https://rgl.faa.gov/
Regulatory_and_Guidance_Library/

(d) Subject
Air Transport Association (ATA) of
America Code 53, Fuselage.
(e) Reason
(c) Applicability
(1) This AD applies to Bombardier, Inc.
Model CL–600–2B19 (Regional Jet Series 100
& 440) airplanes, certificated in any category,
serial numbers 7003 and subsequent.
(2) This AD requires revisions to certain
operator maintenance documents to include
new inspections. Compliance with these
inspections is required by 14 CFR 91.403(c).
For airplanes that have been previously
modified, altered, or repaired in the areas
addressed by these inspections, the operator
may not be able to accomplish the
inspections described in the revisions. In this
This AD was prompted by multiple reports
of cracks on the forward face of the rear
pressure bulkhead (RPB) web. We are issuing
this AD to detect and correct cracking in the
RPB, which could result in reduced
structural integrity and rapid decompression
of the airplane.
(f) Compliance
You are responsible for having the actions
required by this AD performed within the
compliance times specified, unless the
actions have already been done.

ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for Agusta
S.p.A. (Agusta) Model A109E and
Model A109S helicopters with certain
lower semichannel assemblies installed.
This AD requires a one-time inspection
of the lower semichannel assemblies to
determine if metallic spacers are
installed. If the metallic spacers are
installed, this AD requires an inspection
for the correct installation of the
metallic spacers on the semichannels
and for the correct seating of the gaskets.
If the metallic spacers are not installed
with rivets, the lower semichannel
assemblies must be modified, and the
main drive shaft must be inspected for
damage. This AD was prompted by
reports of damage to the main drive
shaft caused by improperly secured
metallic spacers on some A109 model
helicopters. The actions of this AD are
intended to detect missing spacer rivets,
which could allow the metallic spacers
to rotate and lead to damage and failure
of the main drive shaft, and subsequent
loss of helicopter control.
DATES: This AD is effective January 16,
2013.
The Director of the Federal Register
approved the incorporation by reference
of certain documents listed in this AD
as of January 16, 2013.

SUMMARY: We are superseding an existing airworthiness directive (AD)
for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100
& 440) airplanes. That AD currently requires revising the airworthiness
limitations section (AWL) of the Instructions for Continued
Airworthiness (ICA) of the Canadair Regional Jet Maintenance
Requirements Manual (MRM) by incorporating new procedures for
repetitive detailed and special detailed inspections for cracking of
the aft pressure bulkhead. This new AD requires revising the
maintenance program to incorporate a revised task specified in a
certain temporary revision, which requires an improved non-destructive
inspection procedure; and adds airplanes to the applicability. This AD
was prompted by multiple reports of cracks on the forward face of the
rear pressure bulkhead (RPB) web. We are issuing this AD to detect and
correct cracking in the RPB, which could result in reduced structural
integrity and rapid decompression of the airplane.
DATES: This AD becomes effective January 16, 2013.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 16,
2013.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on June 1, 2012 (77 FR
32439), and proposed to supersede AD 2005-23-01, Amendment 39-14359 (70
FR 69073, November 14, 2005). That NPRM proposed to correct an unsafe
condition for the specified products. Transport Canada Civil Aviation
(TCCA) Mandatory Continuing Airworthiness Information (MCAI) states:
Cracks on the forward face of the Rear Pressure Bulkhead (RPB)
web have been discovered on three CL-600-2B19 aeroplanes in-service.
This indicates that the existing inspection requirements of
Airworthiness Limitation (AWL) task 53-61-153 mandated by [TCCA] AD
CF-2005-13R1 are not adequate. Failure of the RPB could result in
rapid decompression of the aeroplane.
A Temporary Revision (TR) has been made to Part 2 of the
Maintenance Requirements Manual (MRM) to revise the existing AWL
task by introducing an improved Non-Destructive Inspection (NDI)
procedure to ensure that fatigue cracking of the RPB is detected and
corrected.
This [TCCA] directive mandates the incorporation of a new NDI
procedure for AWL task number 53-61-153.
You may obtain further information by examining the MCAI in the AD
docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comments received.
Request To Remove Certain Paragraphs of the NPRM (77 FR 32439, June 1,
2012)
Air Wisconsin requested that we remove paragraphs (g) and (h) from
the NPRM (77 FR 32439, June 1, 2012) because paragraph (i) of the NPRM
supersedes those paragraphs. Air Wisconsin stated several examples of
how paragraphs (g) and (h) are superseded by paragraph (i) of the NPRM.
We disagree with the commenter's request to remove paragraphs (g)
and (h) from this final rule. We find it necessary to restate those
paragraphs in this final rule to ensure the existing inspections are
done until the required maintenance program revision specified in
paragraph (i) of this AD is accomplished. In addition, if an airplane
is imported into the United States, it is necessary to accomplish the
requirements of paragraph (g) of this AD before the airplane may be
operated in this country.
However, we find that clarification of paragraph (i) of this AD is
necessary. Once the maintenance program revision is accomplished, the
restated requirements of paragraph (g) of this AD are terminated.
Therefore, we have revised the last sentence of paragraph (i) of this
AD to specify that doing the revision required by paragraph (i) of this
AD terminates the requirements of paragraph (g) of this AD.
In addition, we have retained paragraph (h) in this final rule
because it is necessary to allow Canadair Regional Jet Temporary
Revision TR 2B-2109, dated October 13, 2005, to be removed from the
maintenance requirements manual once a general revision is done.
Further, we have determined that it is necessary to add a paragraph
similar to paragraph (h) of this AD to allow removal of the temporary
revision specified in paragraph (i) of this AD. Accordingly, we have
revised this final rule to add new paragraph (k) to this AD to specify
that information. Subsequent paragraphs have been reidentified.
Request To Revise Serial Numbers
Air Wisconsin requested that we correct the serial numbers in
paragraph (c) or (g) of the NPRM (77 FR 32439, June 1, 2012) for
consistency.
We disagree with the request. The serial numbers specified in
paragraph (g) of this AD are only those that were part of the
applicability of AD 2005-23-01, Amendment 39-14359 (70 FR 69073,
November 14, 2005). Paragraph (c) of this AD lists all serial numbers
that are affected by this new AD.
Requests To Clarify Compliance Time
In regard to paragraph (i)(2) of the NPRM (77 FR 32439, June 1,
2012), Air Wisconsin requested we clarify that, if the last inspection
performed met the requirements of AWL 53-61-153 specified in Bombardier
TR 2B-2187, dated June 22, 2011, to Appendix B--Airworthiness
Limitations, of Part 2 of the Bombardier CL-600-2B19 MRM, the next
inspection cycle as specified in that TR is acceptable provided that
interval is not greater than that specified in Bombardier TR 2B-2187,
dated June 22, 2011.
In addition, Comair requested that we provide credit for paragraph
(i) of the NPRM (77 FR 32439, June 1, 2012) for operators that
performed previous inspections using the special detailed inspection
option specified in AWL 53-61-153 of the Canadair Regional Jet TR 2B-
2109, dated October 13, 2005, to Appendix B, ``Airworthiness
Limitations,'' of Part 2 of the Canadair Regional Jet MRM. Comair
stated that it requested this credit so that operators would not be
subject to the initial compliance time specified in paragraph (i)(1) or
(i)(2) of the NPRM (77 FR 32439, June 1, 2012).
We agree to clarify the inspection compliance time. We agree that,
if the last special detailed inspection (not the detailed visual
inspection) performed met the requirements of AWL 53-61-153 specified
in Bombardier TR 2B-2187, dated June 22, 2011; or Canadair Regional Jet
TR 2B-2109, dated October
[[Page 73904]]
13, 2005; to Appendix B--Airworthiness Limitations, of Part 2 of the
Bombardier CL-600-2B19 MRM; the next inspection should be at the next
compliance time specified in AWL 53-61-153 of Bombardier TR 2B-2187,
dated June 22, 2011 (i.e., within 4,360 landings since the last
inspection). We have changed paragraph (i) of this AD to state that for
airplanes that have already complied with AWL 53-61-153 of Bombardier
TR 2B-2187, dated June 22, 2011, or the special detailed inspection
option specified in Canadair Regional Jet TR 2B-2109, dated October 13,
2005, the initial compliance time for AWL 53-61-153 is within 4,360
flight cycles after accomplishing the most recent special detailed
inspection, or within 1,500 flight cycles after accomplishing the most
recent detailed inspection as specified in AWL 53-61-153 of Canadair
Regional Jet TR 2B-2109, dated October 13, 2005, whichever occurs
later.
Request To Approve Previous Alternative Methods of Compliance (AMOC)
Air Wisconsin requested that a statement be added to paragraph (k)
of the NPRM (77 FR 32439, June 1, 2012) approving use of existing AMOCs
that were approved previously in accordance with AD 2005-23-01,
Amendment 39-14359 (70 FR 69073, November 14, 2005).
We agree to allow existing AMOCs approved in accordance with AD
2005-23-01, Amendment 39-14359 (70 FR 69073, November 14, 2005), as
AMOCs for the corresponding requirements of paragraphs (g) and (h) of
this AD only. We have revised paragraph (l)(1) of this AD (referred to
as paragraph (k)(1) of the NPRM (77 FR 32439, June 1, 2012))
accordingly.
Request To Remove Reference to a Certain TR
Air Wisconsin requested that we remove the reference to Canadair
Regional Jet TR 2B-2109, dated October 13, 2005, to Appendix B--
Airworthiness Limitations, of Part 2 of the Bombardier CL-600-2B19 MRM
from paragraph (j) of the NPRM (77 FR 32439, June 1, 2012). Air
Wisconsin noted that Canadair Regional Jet TR 2B-2109, dated October
13, 2005, conflicts with Bombardier TR 2B-2187, dated June 22, 2011,
and stated that Bombardier TR 2B-2187, dated June 22, 2011,
specifically removed the ``visual inspection'' option that was in
Canadair Regional Jet TR 2B-2109, dated October 13, 2005.
We agree with the request for the reasons stated by the commenter.
We have removed the reference to Canadair Regional Jet TR 2B-2109,
dated October 13, 2005, to Appendix B--Airworthiness Limitations, of
Part 2 of the Bombardier CL-600-2B19 MRM, from paragraph (j) of this
AD. Paragraph (i) of this AD requires that the maintenance program be
revised to incorporate Bombardier TR 2B-2187, dated June 22, 2011.
Paragraph (i) of this AD also specifies that once the revision is done,
the requirements of paragraph (g) of this AD are terminated (paragraph
(g) of the AD incorporated Bombardier TR 2B-2109, dated October 13,
2005).
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously and minor editorial
changes. We have determined that these changes:
Are consistent with the intent that was proposed in the
NPRM (77 FR 32439, June 1, 2012) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 32439, June 1, 2012).
Costs of Compliance
We estimate that this AD will affect about 586 products of U.S.
registry.
The actions that are required by AD 2005-23-01, Amendment 39-14359
(70 FR 69073, November 14, 2005), and retained in this AD take about 2
work-hours per product, at an average labor rate of $85 per work hour.
Based on these figures, the estimated cost of the currently required
actions is $170 per product.
We estimate that it will take about 1 work-hour per product to
comply with the new basic requirements of this AD. The average labor
rate is $85 per work-hour. Based on these figures, we estimate the cost
of this AD to the U.S. operators to be $49,810, or $85 per product.
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 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 the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
Examining the AD Docket
You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM (77 FR 32439, June 1, 2012),
the regulatory evaluation, any comments received, and other
information. The street address for the Docket Operations office
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
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:
[[Page 73905]]
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing airworthiness directive (AD)
2005-23-01, Amendment 39-14359 (70 FR 69073, November 14, 2005), and
adding the following new AD:
2012-25-02 Bombardier, Inc.: Amendment 39-17283. Docket No. FAA-
2012-0496; Directorate Identifier 2011-NM-263-AD.
(a) Effective Date
This airworthiness directive (AD) becomes effective January 16,
2013.
(b) Affected ADs
This AD supersedes AD 2005-23-01, Amendment 39-14359 (70 FR
69073, November 14, 2005).
(c) Applicability
(1) This AD applies to Bombardier, Inc. Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes, certificated in any
category, serial numbers 7003 and subsequent.
(2) This AD requires revisions to certain operator maintenance
documents to include new inspections. Compliance with these
inspections is required by 14 CFR 91.403(c). For airplanes that have
been previously modified, altered, or repaired in the areas
addressed by these inspections, the operator may not be able to
accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (l)(1) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued damage tolerance of the affected structure. The FAA
has provided guidance for this determination in FAA Advisory
Circular (AC) 25.1529-1A, dated November 20, 2007 (https://
rgl.faa.gov/Regulatory--and--Guidance--Library/
rgAdvisoryCircular.nsf/list/AC%2025.1529-1A/$FILE/AC%2025.1529-
1A.pdf).
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Reason
This AD was prompted by multiple reports of cracks on the
forward face of the rear pressure bulkhead (RPB) web. We are issuing
this AD to detect and correct cracking in the RPB, which could
result in reduced structural integrity and rapid decompression of
the airplane.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.
(g) Retained Revision to the Airworthiness Limitations (AWL) Section
This paragraph restates the requirements of paragraph (f) of AD
2005-23-01, Amendment 39-14359 (70 FR 69073, November 14, 2005). For
airplanes having serial numbers 7003 through 8025 inclusive, 8030,
and 8034: Within 30 days after November 29, 2005 (the effective date
of AD 2005-23-01), revise the AWL section of the Instructions for

Limitations,'' by incorporating the information specified in AWL 53-
61-153 of the Canadair Regional Jet Temporary Revision (TR) 2B-2109,
dated October 13, 2005, into the AWL section. Perform the applicable
detailed and special detailed inspections for cracking of the aft
pressure bulkhead, as specified in that TR, at the applicable
compliance time specified in table 1 to paragraph (g) of this AD.
Repeat the detailed inspection thereafter at intervals not to exceed
1,085 flight cycles, and repeat the special detailed inspection
thereafter at intervals not to exceed 4,360 flight cycles, in
accordance with the procedures specified in AWL 53-61-153, as
introduced by Canadair Regional Jet TR 2B-2109, dated October 13,
2005, to Appendix B, ``Airworthiness Limitations, of Part 2 of the
Canadair Regional Jet MRM. Accomplishing the revision required by
paragraph (i) of this AD terminates the requirements of this
paragraph.
