Airworthiness Directives; Bombardier Model CL-600-2C10 (Regional
Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series
705), and CL-600-2D24 (Regional Jet Series 900) Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This 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 the
fuel tank wiring harness installation, and the hydraulic system No.
3 temperature transducer, among other items] are required to prevent
potential ignition sources inside the fuel system, which could
result in a fuel tank explosion. * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective April 16, 2008.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 16,
2008.

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 January 4, 2008 (73
FR 830). (A correction of the rule was published in the Federal
Register on January 31, 2008 (73 FR 5767).) That NPRM proposed to
correct an unsafe condition for the specified products. The 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
the fuel tank wiring harness installation, and the hydraulic system
No. 3 temperature transducer, 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 Models CL-600-2C10, CL-600-2D15 and CL-600-
2D24 Maintenance Requirements Manual, CSP B-053, Part 2, Section 3
``Fuel System Limitations'' to introduce the required maintenance
tasks.
The corrective action is revising the Airworthiness Limitations Section
of the Instructions for Continued Airworthiness to incorporate new
limitations for fuel tank systems. 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 received no comments on the NPRM or on the determination of
the cost to the public.
Changes Made to This AD
For standardization purposes, we have revised this AD in the
following ways:
We revised paragraph (f)(1) of this AD to add a reference
to ``Transport Canada Civil Aviation (TCCA) (or its delegated agent)''
for approval of a particular document. We also revised paragraph (f)(2)
of this AD to specify that no alternative inspections or inspection
intervals may be used unless they are part of a later approved revision
of Section 3, ``Fuel System Limitations,'' of Part 2 of Bombardier CL-
600-2C10, CL-600-2D15, and CL-600-2D24 Maintenance Requirements Manual
CSP
[[Page 13099]]
B-053, Revision 9, dated July 20, 2007, or unless they are approved as
an alternative method of compliance (AMOC). Inclusion of this paragraph
in the AD is intended to ensure that the AD-mandated airworthiness
limitations changes are treated the same as the airworthiness
limitations issued with the original type certificate.
In addition, we have simplified the language in Note 1 of
this AD to clarify that an operator must request approval for an
alternative method of compliance (AMOC) if an operator cannot
accomplish the required inspections because an airplane has been
previously modified, altered, or repaired in the areas addressed by the
required inspections.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD with the changes described
previously. We also determined that these changes will not increase the
economic burden on any operator or increase the scope of the AD.
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 required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect about 289 products of U.S.
registry. We also estimate that it will 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 AD on U.S. operators to be $23,120, 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 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 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); 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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://
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, 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.

Adoption of the Amendment
0
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:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2008-06-01 Bombardier, Inc. (Formerly Canadair): Amendment 39-15413.
Docket No. FAA-2007-0414; Directorate Identifier 2007-NM-340-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective April
16, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Bombardier Model CL-600-2C10
(Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional
Jet Series 705), and CL-600-2D24 (Regional Jet Series 900)
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 (g)(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
the fuel tank wiring harness installation, and the hydraulic system
No. 3 temperature transducer, 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 Models CL-600-2C10, CL-600-2D15 and CL-600-
2D24 Maintenance Requirements Manual, CSP B-053, Part 2, Section 3
``Fuel
[[Page 13100]]
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.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 60 days after the effective date of this AD, or on or
before December 16, 2008, whichever occurs first, revise the ALS of
the Instructions for Continued Airworthiness to incorporate the
inspection requirements Section 3, ``Fuel System Limitations,'' of
Part 2 of Bombardier CL-600-2C10, CL-600-2D15, and CL-600-2D24
Maintenance Requirements Manual CSP B-053, Revision 9, dated July
20, 2007 (``the MRM''). For task numbers 24-90-00-601, 24-90-00-602,
28-00-00-601, 28-11-23-601, 28-11-23-602, 28-12-13-601, 29-30-00-
601, and 29-30-00-602, the initial compliance times start from the
later of the times specified in paragraphs (f)(1)(i) and (f)(1)(ii)
of this AD, and the repetitive inspections must be accomplished
thereafter at the interval specified in the MRM, except as provided
by paragraphs (f)(1) and (g)(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).
(i) The effective date of this AD.
(ii) The date of issuance of the original Canadian standard
airworthiness certificate or the date of issuance of the original
Canadian export certificate of airworthiness.
(2) After accomplishing the actions specified in paragraph
(f)(1) of this AD, no alternative inspections or inspection
intervals may be used, unless the inspection or interval is part of
a later revision of the Section 3, ``Fuel System Limitations,'' of
Part 2 of Bombardier CL-600-2C10, CL-600-2D15, and CL-600-2D24
Maintenance Requirements Manual CSP B-053, Revision 9, dated July
20, 2007, that is approved by the Manager, New York ACO, FAA, or
TCCA (or its delegated agent); or unless the inspection or interval
is approved as an alternative method of compliance (AMOC) in
accordance with the procedures specified in paragraph (g)(1) of this
AD.
