ACTION:
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for the
products listed above that would
supersede an existing AD. This
proposed AD results from mandatory
continuing airworthiness information
(MCAI) originated by an aviation
authority of another country to identify
and correct an unsafe condition on an
aviation product. The MCAI describes
the unsafe condition as:
Bombardier Aerospace has completed a
system safety review of the aircraft fuel
system against fuel tank safety standards
* * *.
[A]ssessment showed that supplemental
maintenance tasks [for certain bonding
jumpers, wiring harnesses, and hydraulic
systems, among other items] are required to
prevent potential ignition sources inside the
fuel system, which could result in a fuel tank
explosion. * * *
The proposed AD would require actions
that are intended to address the unsafe
condition described in the MCAI.
DATES: We must receive comments on
this proposed AD by July 21, 2008.
ADDRESSES: You may send comments by
any of the following methods:
• Federal eRulemaking Portal: Go to

Discussion
On February 28, 2008, we issued AD
2008–06–02, Amendment 39–15414 (73
FR 13100, March 12, 2008). That AD
required actions intended to address an
unsafe condition on the products listed
above.
Since we issued AD 2008–06–02, we
have determined that, for certain
airplanes, the initial compliance times
for doing the tasks specified in
paragraph (f)(1) of that AD must be
reduced. AD 2008–06–02 resulted from
Canadian Airworthiness Directive CF–
2007–29, dated November 22, 2007
(referred to after this as ‘‘the MCAI’’).
The MCAI does not provide an initial
compliance time for doing the tasks for
certain airplanes. In AD 2008–06–02, for
those airplanes, we required an initial
compliance time that started from the
effective date of the AD, or the date of
issuance of the original Canadian
standard airworthiness certificate or the
date of issuance of the original Canadian
export certificate of airworthiness,
whichever occurs later. Although the
initial compliance time for doing the
tasks is unstated in the MCAI, we have
determined that the intent of the MCAI
is for the initial compliance time to start
from the initial delivery date of the
airplane in order to address the
identified unsafe condition in a timely
manner.
This proposed AD would require
reduced thresholds for the initial
compliance times for the airplanes and
tasks that are not identified in
paragraphs (f)(2), (f)(3), and (f)(4) of AD
2008–06–02. You may obtain further
VerDate Aug<31>2005

information by examining the MCAI in
the AD docket.
FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have proposed
different actions in this AD from those
in the MCAI in order to follow FAA
policies. Any such differences are
highlighted in a NOTE within the
proposed AD.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 689 products of U.S.
registry. We also estimate that it would
take about 1 work-hour per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Based on
these figures, we estimate the cost of the
proposed AD on U.S. operators to be
$55,120, or $80 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
PO 00000
Frm 00008
Fmt 4702
Sfmt 4702
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 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 this 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.

The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:

[Amended]
2. The FAA amends § 39.13 by
removing Amendment 39–15414 (73 FR
13100, March 12, 2008) and adding the
following new AD:
Bombardier, Inc. (Formerly Canadair):
Docket No. FAA–2008–0643; Directorate
Identifier 2008–NM–094–AD.
Comments Due Date
(a) We must receive comments by July 21,

20JNP1
Federal Register / Vol. 73, No. 120 / Friday, June 20, 2008 / Proposed Rules
Applicability
(c) This AD applies to all Bombardier
Model CL–600–2B19 (Regional Jet Series 100
& 440) airplanes, certificated in any category,
all serial numbers.
Note 1: 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 (h)(1) of this AD. The request
should include a description of changes to
the required inspections that will ensure the
continued operational safety of the airplane.
Subject
(d) Air Transport Association (ATA) of
America Code 28: Fuel.
sroberts on PROD1PC70 with PROPOSALS
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Bombardier Aerospace has completed a
system safety review of the aircraft fuel
system against fuel tank standards
introduced in Chapter 525 of the
Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002–043. The
identified non-compliances were then
assessed using Transport Canada Policy
Letter No. 525–001, to determine if
mandatory corrective action is required.
The assessment showed that supplemental
maintenance tasks [for certain bonding
jumpers, wiring harnesses, and hydraulic
systems, among other items] are required to
prevent potential ignition sources inside the
fuel system, which could result in a fuel tank
explosion. Revision has been made to
Canadair Regional Jet Model CL–600–2B19
Maintenance Requirements Manual, CSP A–
053, Part 2, Appendix D, ‘‘Fuel System
Limitations’’ to introduce the required
maintenance tasks.
The corrective action is revising the
Airworthiness Limitations Section (ALS) of
the Instructions for Continued Airworthiness
to incorporate new limitations for fuel tank
systems.
Restatement of Certain Requirements of AD
2008–06–02
(f) Unless already done, do the following
actions.
(1) Within 60 days after April 16, 2008 (the
effective date of AD 2008–06–02), revise the
Airworthiness Limitations Section (ALS) of
the Instructions for Continued Airworthiness
to incorporate the inspection and
maintenance requirements, as applicable, in
Canadair Regional Jet Model CL–600–2B19
Airworthiness Requirements in the
Maintenance Requirements Manual, CSP A–
053, Part 2, Appendix D, ‘‘Fuel System
Limitations,’’ Revision 7, dated May 10, 2007
(‘‘the MRM’’), task numbers 28–11–00–601,
28–11–00–602, 28–11–00–603, 28–11–00–
604, 29–33–01–601, and 29–33–01–602.

Except as required by paragraph (g)(1) of this
AD, for those task numbers, the initial
compliance times start at the applicable time
specified in paragraphs (f)(2), (f)(3), and (f)(4)
of this AD, and the repetitive inspections
must be accomplished thereafter at the
interval specified in the MRM, except as
provided by paragraphs (f)(5) and (h)(1) of
this AD. Accomplishing the revision in
accordance with a later revision of the MRM
is an acceptable method of compliance if the
revision is approved by the Manager, New
York Aircraft Certification Office (ACO),
FAA), or Transport Canada Civil Aviation
(TCCA) (or its delegated agent).
(2) For airplanes having more than 15,000
flight hours as of April 16, 2008, the initial

28–11–00–602, 28–11–00–603, and 28–11–
00–604 is within 5,000 flight hours after
April 16, 2008. Thereafter, these tasks must
be accomplished within the repetitive
interval specified in Canadair Regional Jet
Model CL–600–2B19, Airworthiness
Requirements in the Maintenance
Requirements Manual, CSP A–053, Part 2,
Appendix D, ‘‘Fuel System Limitations,’’
Revision 7, dated May 10, 2007.
(3) For Task 29–33–01–601, the initial
compliance time is within 5,000 flight hours
after April 16, 2008. Thereafter, task 29–33–
01–601 must be accomplished within the
repetitive interval specified in Canadair
Regional Jet Model CL–600–2B19,
Airworthiness Requirements in the
Maintenance Requirements Manual, CSP A–
053, Part 2, Appendix D, ‘‘Fuel System
Limitations,’’ Revision 7, dated May 10,
2007.
(4) For airplanes having more than 27,500
flight hours as of April 16, 2008, the initial
compliance time for Task 29–33–01–602 is
within 2,500 flight hours after April 16, 2008.
Thereafter, this task must be accomplished
within the repetitive interval specified in
Canadair Regional Jet Model CL–600–2B19,
Airworthiness Requirements in the
Maintenance Requirements Manual, CSP A–
053, Part 2, Appendix D, ‘‘Fuel System
Limitations,’’ Revision 7, dated May 10,
2007.
(5) After accomplishing the actions
specified in paragraphs (f)(1), (f)(2), (f)(3),
and (f)(4) of this AD, no alternative
inspections/limitation tasks or inspection/
limitation task intervals may be used unless
the inspections/limitation tasks or
inspection/limitation task intervals are part
of a later approved revision of Canadair
Regional Jet Model CL–600–2B19,
Airworthiness Requirements in the
Maintenance Requirements Manual, CSP A–
053, Part 2, Appendix D, ‘‘Fuel System
Limitations,’’ Revision 7, dated May 10,
2007, that is approved by the Manager, New
York ACO, FAA, or TCCA (or its delegated
agent); or unless the inspection/limitation
task or inspection/limitation task interval is
approved as an alternative method of
compliance (AMOC) in accordance with the
procedures specified in paragraph (h)(1) of

AGENCY:
SUMMARY: The FAA proposes to
supersede an existing airworthiness
directive (AD) that applies to all
EMBRAER Model EMB–135 airplanes
and Model EMB–145, –145ER, –145MR,
–145LR, –145XR, –145MP, and –145EP
airplanes. The existing AD currently
requires replacing the metallic tubes
enclosing the vent and pilot valve wires
in the left- and right-hand wing fuel
tanks with non-conductive hoses. This
proposed AD would add airplanes to the
applicability of the existing AD. This
proposed AD results from fuel system
reviews conducted by the manufacturer.
We are proposing this AD to prevent an
ignition source inside the fuel tank that
could ignite fuel vapor and cause a fuel
tank explosion and loss of the airplane.

Discussion
On June 1, 2007, we issued AD 2007–
12–17, amendment 39–15095 (72 FR
32780, June 14, 2007), for certain
EMBRAER Model EMB–135 airplanes
and Model EMB–145, –145ER, –145MR,
–145LR, –145XR, –145MP, and –145EP
airplanes. That AD requires replacing
the metallic tubes enclosing the vent
and pilot valve wires in the left- and
right-hand wing fuel tanks with nonconductive hoses. That AD resulted
from fuel system reviews conducted by
the manufacturer. We issued that AD to
prevent an ignition source inside the
fuel tank that could ignite fuel vapor
and cause a fuel tank explosion and loss
of the airplane.
Actions Since Existing AD Was Issued
Since we issued AD 2007–12–17, we
have been notified by the airplane
manufacturer that additional airplanes
are also subject to the unsafe condition
identified in the existing AD.
Relevant Service Information
EMBRAER has issued Service Bulletin
145–28–0023, Revision 11, dated
December 4, 2007. The procedures
specified in Revision 11 of the service
bulletin are essentially the same as
those described in EMBRAER Service
Bulletin 145–28–0023, Revision 07,
dated February 7, 2007. We referred to
Revision 07 of the service bulletin in AD
2007–12–17 as the appropriate source of
service information for actions required
in that AD for certain airplanes.
However, Revision 11 of the service
bulletin includes airplanes that are not
identified in Revision 07.
Accomplishing the actions specified in
the service information is intended to
adequately address the unsafe
condition.
U.S. Type Certification of the Airplane
These airplane models are
manufactured in Brazil and are typecertificated for operation in the United
States under the provisions of section
21.29 of the Federal Aviation
Regulations (14 CFR 21.29) and the
applicable bilateral airworthiness
agreement.
This proposed AD would supersede
AD 2007–12–17 and would retain the
requirements of the existing AD. This
proposed AD would also add airplanes
to the applicability of the existing AD.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above that would supersede an existing AD. This
proposed AD results from mandatory continuing airworthiness information
(MCAI) originated by an aviation authority of another country to
identify and correct an unsafe condition on an aviation product. The
MCAI describes the unsafe condition as:
Bombardier Aerospace has completed a system safety review of the
aircraft fuel system against fuel tank safety standards * * *.
[A]ssessment showed that supplemental maintenance tasks [for
certain bonding jumpers, wiring harnesses, and hydraulic systems,
among other items] are required to prevent potential ignition
sources inside the fuel system, which could result in a fuel tank
explosion. * * *
The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by July 21, 2008.

Discussion
On February 28, 2008, we issued AD 2008-06-02, Amendment 39-15414
(73 FR 13100, March 12, 2008). That AD required actions intended to
address an unsafe condition on the products listed above.
Since we issued AD 2008-06-02, we have determined that, for certain
airplanes, the initial compliance times for doing the tasks specified
in paragraph (f)(1) of that AD must be reduced. AD 2008-06-02 resulted
from Canadian Airworthiness Directive CF-2007-29, dated November 22,
2007 (referred to after this as ``the MCAI'').
The MCAI does not provide an initial compliance time for doing the
tasks for certain airplanes. In AD 2008-06-02, for those airplanes, we
required an initial compliance time that started from the effective
date of the AD, or the date of issuance of the original Canadian
standard airworthiness certificate or the date of issuance of the
original Canadian export certificate of airworthiness, whichever occurs
later. Although the initial compliance time for doing the tasks is
unstated in the MCAI, we have determined that the intent of the MCAI is
for the initial compliance time to start from the initial delivery date
of the airplane in order to address the identified unsafe condition in
a timely manner.
This proposed AD would require reduced thresholds for the initial
compliance times for the airplanes and tasks that are not identified in
paragraphs (f)(2), (f)(3), and (f)(4) of AD 2008-06-02. You may obtain
further information by examining the MCAI in the AD docket.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 689 products of U.S. registry. We also estimate that
it would take about 1 work-hour per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $55,120, or $80 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 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 this 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.
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 FAA amends Sec. 39.13 by removing Amendment 39-15414 (73 FR
13100, March 12, 2008) and adding the following new AD:
Bombardier, Inc. (Formerly Canadair): Docket No. FAA-2008-0643;
Directorate Identifier 2008-NM-094-AD.
Comments Due Date
(a) We must receive comments by July 21, 2008.
Affected ADs
(b) The proposed AD supersedes AD 2008-06-02, Amendment 39-
15414.
[[Page 35097]]
Applicability
(c) This AD applies to all Bombardier Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes, certificated in any
category, all serial numbers.
Note 1: 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 (h)(1) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued operational safety of the airplane.
Subject
(d) Air Transport Association (ATA) of America Code 28: Fuel.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Bombardier Aerospace has completed a system safety review of the
aircraft fuel system against fuel tank standards introduced in
Chapter 525 of the Airworthiness Manual through Notice of Proposed
Amendment (NPA) 2002-043. The identified non-compliances were then
assessed using Transport Canada Policy Letter No. 525-001, to
determine if mandatory corrective action is required.
The assessment showed that supplemental maintenance tasks [for
certain bonding jumpers, wiring harnesses, and hydraulic systems,
among other items] are required to prevent potential ignition
sources inside the fuel system, which could result in a fuel tank
explosion. Revision has been made to Canadair Regional Jet Model CL-
600-2B19 Maintenance Requirements Manual, CSP A-053, Part 2,
Appendix D, ``Fuel System Limitations'' to introduce the required
maintenance tasks.
The corrective action is revising the Airworthiness Limitations
Section (ALS) of the Instructions for Continued Airworthiness to
incorporate new limitations for fuel tank systems.
Restatement of Certain Requirements of AD 2008-06-02
(f) Unless already done, do the following actions.
(1) Within 60 days after April 16, 2008 (the effective date of
AD 2008-06-02), revise the Airworthiness Limitations Section (ALS)
of the Instructions for Continued Airworthiness to incorporate the
inspection and maintenance requirements, as applicable, in Canadair
Regional Jet Model CL-600-2B19 Airworthiness Requirements in the
Maintenance Requirements Manual, CSP A-053, Part 2, Appendix D,
``Fuel System Limitations,'' Revision 7, dated May 10, 2007 (``the
MRM''), task numbers 28-11-00-601, 28-11-00-602, 28-11-00-603, 28-
11-00-604, 29-33-01-601, and 29-33-01-602. Except as required by
paragraph (g)(1) of this AD, for those task numbers, the initial
compliance times start at the applicable time specified in
paragraphs (f)(2), (f)(3), and (f)(4) of this AD, and the repetitive
inspections must be accomplished thereafter at the interval
specified in the MRM, except as provided by paragraphs (f)(5) and
(h)(1) of this AD. Accomplishing the revision in accordance with a
later revision of the MRM is an acceptable method of compliance if
the revision is approved by the Manager, New York Aircraft
Certification Office (ACO), FAA), or Transport Canada Civil Aviation
(TCCA) (or its delegated agent).
(2) For airplanes having more than 15,000 flight hours as of
April 16, 2008, the initial compliance time for Tasks 28-11-00-601,
28-11-00-602, 28-11-00-603, and 28-11-00-604 is within 5,000 flight
hours after April 16, 2008. Thereafter, these tasks must be
accomplished within the repetitive interval specified in Canadair
Regional Jet Model CL-600-2B19, Airworthiness Requirements in the
Maintenance Requirements Manual, CSP A-053, Part 2, Appendix D,
``Fuel System Limitations,'' Revision 7, dated May 10, 2007.
(3) For Task 29-33-01-601, the initial compliance time is within
5,000 flight hours after April 16, 2008. Thereafter, task 29-33-01-
601 must be accomplished within the repetitive interval specified in
Canadair Regional Jet Model CL-600-2B19, Airworthiness Requirements
in the Maintenance Requirements Manual, CSP A-053, Part 2, Appendix
D, ``Fuel System Limitations,'' Revision 7, dated May 10, 2007.
(4) For airplanes having more than 27,500 flight hours as of
April 16, 2008, the initial compliance time for Task 29-33-01-602 is
within 2,500 flight hours after April 16, 2008. Thereafter, this
task must be accomplished within the repetitive interval specified
in Canadair Regional Jet Model CL-600-2B19, Airworthiness
Requirements in the Maintenance Requirements Manual, CSP A-053, Part
2, Appendix D, ``Fuel System Limitations,'' Revision 7, dated May
10, 2007.
(5) After accomplishing the actions specified in paragraphs
(f)(1), (f)(2), (f)(3), and (f)(4) of this AD, no alternative
inspections/limitation tasks or inspection/limitation task intervals
may be used unless the inspections/limitation tasks or inspection/
limitation task intervals are part of a later approved revision of
Canadair Regional Jet Model CL-600-2B19, Airworthiness Requirements
in the Maintenance Requirements Manual, CSP A-053, Part 2, Appendix
D, ``Fuel System Limitations,'' Revision 7, dated May 10, 2007, that
is approved by the Manager, New York ACO, FAA, or TCCA (or its
delegated agent); or unless the inspection/limitation task or
inspection/limitation task interval is approved as an alternative
method of compliance (AMOC) in accordance with the procedures
specified in paragraph (h)(1) of this AD.
New Requirements of This AD: Actions and Compliance
(g) Unless already done, do the following actions.
(1) At the times specified in paragraphs (g)(1)(i) and
(g)(1)(ii) of this AD, as applicable, do the initial inspection for
Tasks 28-11-00-601, 28-11-00-602, 28-11-00-603, 28-11-00-604, and
29-33-01-602, as applicable, in the MRM, and thereafter repeat the
inspection at the applicable interval specified in the MRM, except
as provided by (g)(2) of this AD.
(i) For airplanes not identified in paragraph (f)(2) of this AD,
the initial compliance time for Tasks 28-11-00-601, 28-11-00-602,
28-11-00-603, and 28-11-00-604 is before the accumulation of 20,000
total flight hours, or within 5,000 flight hours after the effective
date of this AD, whichever occurs later.
(ii) For airplanes not identified in paragraph (f)(4) of this
AD, the initial compliance time for Task 29-33-01-602 is before the
accumulation of 30,000 total flight hours, or within 2,500 flight
hours after the effective date of this AD, whichever occurs later.
(2) After accomplishing the actions specified in paragraphs
(g)(1)of this AD, no alternative inspections/limitation tasks or
inspection/limitation task intervals may be used unless the
inspections/limitation tasks or inspection/limitation task intervals
are part of a later approved revision of Canadair Regional Jet Model
CL-600-2B19, Airworthiness Requirements in the Maintenance
Requirements Manual, CSP A-053, Part 2, Appendix D, ``Fuel System
Limitations,'' Revision 7, dated May 10, 2007, that is approved by
the Manager, New York ACO, FAA, or TCCA (or its delegated agent); or
unless the inspection/limitation task or inspection/limitation task
interval is approved as an alternative method of compliance (AMOC)
in accordance with the procedures specified in paragraph (h)(1) of
this AD.
