ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding an existing airworthiness directive (AD)
that applies to 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:
There has been numerous reported failures of the Regional Jet
engine TCGB [throttle control gearbox] P/Ns: 2100140-003, 2100140-
005 & 2100140-007. Some of these failures have resulted in in-flight
engine shutdowns. Post incident investigations revealed that
excessive wear within the
[[Page 10217]]
engine TCGB could alter the rigging position or cause the throttle
to jam. With the rigging position altered, movement of the throttle
lever towards the idle position can result in throttle moving too
close to the fuel shut-off position, which potentially, can cause
the engine to flame out.
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective March 31, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of March 31,
2011.

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 October 21, 2010 (75
FR 64960), and proposed to supersede AD 2005-06-04, Amendment 39-14012
(70 FR 12963, March 17, 2005). That NPRM proposed to correct an unsafe
condition for the specified products.
Since we issued AD 2005-06-04, the inspection for the throttle
control gearbox (TCGB) required by that AD has been transcribed in a
new certification maintenance requirement (CMR) task. This AD mandates
the incorporation of new CMR Task C76-11-127-01 into the Bombardier CL-
600-2B19 Maintenance Requirements Manual (MRM) as introduced by
Bombardier Temporary Revision 2A-47. Transport Canada Civil Aviation
(TCCA), which is the aviation authority for Canada, has issued Canadian
Airworthiness Directive CF-2004-01R2, dated September 29, 2009
(referred to after this as ``the MCAI''), to correct an unsafe
condition for the specified products. The MCAI states:
There has been numerous reported failures of the Regional Jet
engine TCGB [throttle control gearbox] P/Ns: 2100140-003, 2100140-
005 & 2100140-007. Some of these failures have resulted in in-flight
engine shutdowns. Post incident investigations revealed that
excessive wear within the engine TCGB could alter the rigging
position or cause the throttle to jam. With the rigging position
altered, movement of the throttle lever towards the idle position
can result in throttle moving too close to the fuel shut-off
position, which potentially, can cause the engine to flame out.
Bombardier issued Service Bulletin (SB) 601R-76-019 dated 21
August 2003, to introduce an inspection of, and if required,
replacement of the throttle control gearbox with a serviceable unit.
AD CF-2004-01 was originally issued to mandate the subject
inspection requirement as per SB 601R-76-019 and subsequent
revisions.
The subject TCGB inspection requirements mandated as per the
earlier versions of this [Canadian] AD, are now transcribed in a new
Certification Maintenance Requirement (CMR) task. This revision is
issued to mandate the incorporation of the new CMR task [Task C76-
11-127-01] into the CL-600-2B19 Maintenance Requirements Manual
(MRM), as introduced by the MRM Temporary Revision (TR) 2A-47.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
The NPRM referred to Bombardier Service Bulletin 601R-76-019,
Revision C, dated July 5, 2007, as the appropriate source of service
information for accomplishing certain proposed actions. Bombardier Inc.
has issued Service Bulletin 601R-76-019, Revision D, dated September
23, 2010. This service bulletin does not add any work for the affected
airplanes. We have revised this final rule to refer to Bombardier
Service Bulletin 601R-76-019, Revision D, dated September 23, 2010, as
the appropriate source of service information for accomplishing the
applicable actions.
We have added new paragraph (m) to this final rule to give credit
to operators for accomplishing the applicable actions before the
effective date of this AD in accordance with Bombardier Service
Bulletin 601R-76-019, Revision C, dated July 5, 2007. We have re-
identified subsequent paragraphs accordingly.
The NPRM also referred to Bombardier Temporary Revision 2A-47,
dated May 27, 2009, to Appendix A--Certification Maintenance
Requirements, of Part 2 of the Bombardier CL-600-2B19 Maintenance
Requirements Manual for incorporating new CMR Task C76-11-127-01 into
the maintenance program. Bombardier Inc. has issued Temporary Revision
2A-53, dated December 15, 2010, to Appendix A--Certification
Maintenance Requirements, of Part 2 of the Bombardier CL-600-2B19
Maintenance Requirements Manual. Bombardier Temporary Revision 2A-53,
dated December 15, 2010, was issued to revise the task description of
CMR Task C76-11-127-01. We have revised this final rule to allow
operators to use either Bombardier Temporary Revision 2A-47, dated May
27, 2009; or Bombardier Temporary Revision 2A-53, dated December 15,
2010; for revising the maintenance program to include CMR Task C76-11-
127-01.
The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
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.
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 about 638 products of U.S.
registry.
The actions that are required by AD 2005-06-04 and retained in this
AD take about 7 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 $595 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-
[[Page 10218]]
hour. Based on these figures, we estimate the cost of this AD to the
U.S. operators to be $54,230, 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 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.
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:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing Amendment 39-14012 (70 FR
12963, March 17, 2005) and adding the following new AD:
2011-05-03 Bombardier, Inc.: Amendment 39-16612. Docket No. FAA-
2010-1039; Directorate Identifier 2010-NM-002-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective March
31, 2011.
Affected ADs
(b) The AD supersedes AD 2005-06-04, Amendment 39-14012.
Applicability
(c) This AD applies to Bombardier, Inc. Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes, certificated in any
category, having an engine throttle control gearbox (TCGB) with part
number 2100140-003, 2100140-005, or 2100140-007 installed.
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 (n)(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 has been numerous reported failures of the Regional Jet
engine TCGB P/Ns: 2100140-003, 2100140-005 & 2100140-007. Some of
these failures have resulted in in-flight engine shutdowns. Post
incident investigations revealed that excessive wear within the
engine TCGB could alter the rigging position or cause the throttle
to jam. With the rigging position altered, movement of the throttle
lever towards the idle position can result in throttle moving too
close to the fuel shut-off position, which potentially, can cause
the engine to flame out.
Bombardier issued Service Bulletin (SB) 601R-76-019 dated 21
August 2003, to introduce an inspection of, and if required,
replacement of the throttle control gearbox with a serviceable unit.
AD CF-2004-01 was originally issued to mandate the subject
inspection requirement as per SB 601R-76-019 and subsequent
revisions.
The subject TCGB inspection requirements mandated as per the
earlier versions of this [Canadian] AD, are now transcribed in a new
Certification Maintenance Requirement (CMR) task. This revision is
issued to mandate the incorporation of the new CMR task [Task C76-
11-127-01] into the CL-600-2B19 Maintenance Requirements Manual
(MRM), as introduced by the MRM Temporary Revision (TR) 2A-47.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Restatement of Requirements of AD 2005-06-04, With New Service
Information

FAA AD Differences
Note 5: This AD differs from the MCAI and/or service
information as follows: No differences.
Other FAA AD Provisions
(n) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York Aircraft
[[Page 10220]]
Certification Office (ACO), ANE-170, FAA, has the authority to
approve AMOCs for this AD, if requested using the procedures found
in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request
to your principal inspector or local Flight Standards District
Office, as appropriate. If sending information directly to the ACO,
send it to ATTN: Program Manager, Continuing Operational Safety,
FAA, New York ACO, 1600 Stewart Avenue, Suite 410, Westbury, New
York 11590; telephone 516-228-7300; fax 516-794-5531. Before using
any approved AMOC, notify your appropriate principal inspector, or
lacking a principal inspector, the manager of the local flight
standards district office/certificate holding district office. The
AMOC approval letter must specifically reference this AD.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: A federal agency may not conduct or
sponsor, and a person is not required to respond to, nor shall a
person be subject to a penalty for failure to comply with a
collection of information subject to the requirements of the
Paperwork Reduction Act unless that collection of information
displays a current valid OMB Control Number. The OMB Control Number
for this information collection is 2120-0056. Public reporting for
this collection of information is estimated to be approximately 5
minutes per response, including the time for reviewing instructions,
completing and reviewing the collection of information. All
responses to this collection of information are mandatory. Comments
concerning the accuracy of this burden and suggestions for reducing
