-----------------------------------------------------------------------
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:
* * * [I]ncidents of throttle jam and engine shutdowns, caused
by premature wear of the rack and pinion mechanism of part number
(P/N) 2100140-005 and -007 Engine Throttle Control Gearbox (ETCG),
installed on Bombardier CL-601 and 604 aircraft.
* * * * *
[[Page 63588]]
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective January 8, 2010.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of January 8,
2010.
ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> or in person at the U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,

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 23, 2009 (74 FR
29632). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
There have been various reported incidents of throttle jam and
engine shutdowns, caused by premature wear of the rack and pinion
mechanism of part number (P/N) 2100140-005 and -007 Engine Throttle
Control Gearbox (ETCG), installed on Bombardier CL-601 and 604
aircraft.
Bombardier issued service bulletins (SB) 601-0583 (CL601/601-3A,
-3R) and 604-76-004 (CL 604), introducing periodic inspection of the
affected ETCG rack and pinion mechanisms for wear.
Subject inspection requirement tasks have now been incorporated
into the applicable CL601 and CL604 Time Limits Maintenance Checks
(TLMCs) through Temporary Revisions (TR), TR 5-236 (for CL601), TR
5-236 (for CL601-3A & -3R) and TR 5-2-40 (for CL604).
The required action is revising the Airworthiness Limitations Section
of the Instructions for Continued Airworthiness to incorporate new
repetitive functional tests of the ETCG. 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.
New Note
We have added Note 1 to this AD to clarify compliance with section
91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)).
Updated Contact Information
We have updated paragraph (g)(1) of this AD to provide the
appropriate contact information to use when submitting requests for
approval of an alternative method of compliance (AMOC).
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD with the changes described
previously. We 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 377 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 AD. The average labor rate
is $80 per work-hour. Based on these figures, we estimate the cost of
this AD to the U.S. operators to be $30,160, 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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>; 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.
[[Page 63589]]
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2009-24-18 Bombardier, Inc. (Formerly Canadair): Amendment 39-16112.
Docket No. FAA-2009-0565; Directorate Identifier 2008-NM-217-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective January
8, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Bombardier Model CL-600-2A12 (CL-601)
and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) airplanes,
certificated in any category.
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 76: Engine
controls.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
There have been various reported incidents of throttle jam and
engine shutdowns, caused by premature wear of the rack and pinion
mechanism of part number (P/N) 2100140-005 and -007 Engine Throttle
Control Gearbox (ETCG), installed on Bombardier CL-601 and 604
aircraft.
Bombardier issued service bulletins (SB) 601-0583 (CL601/601-3A,
-3R) and 604-76-004 (CL 604), introducing periodic inspection of the
affected ETCG rack and pinion mechanisms for wear.
Subject inspection requirement tasks have now been incorporated
into the applicable CL601 and CL604 Time Limits Maintenance Checks
(TLMCs) through Temporary Revisions (TR), TR 5-236 (for CL601), TR
5-236 (for CL601-3A & -3R) and TR 5-2-40 (for CL604).
The required action is revising the Airworthiness Limitations
Section of the Instructions for Continued Airworthiness to
incorporate new repetitive functional tests of the ETCG.
