Airworthiness Directives; Bombardier Model CL-600-2B16 (CL-604)
Airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440)
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) that applies to certain Bombardier Model CL-600-2B16 (CL-604)
airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440)
airplanes. These models may be referred to by their marketing
designations as RJ100, RJ200, RJ440, CRJ100, CRJ200, CRJ440, and CL-65.
The existing AD currently requires revising the Emergency Procedures
section of the airplane flight manual (AFM) to advise the flightcrew of
additional procedures to follow in the event of stabilizer trim
runaway. For certain airplanes, the existing AD also requires revising
the Abnormal Procedures section of the AFM to advise the flightcrew of
procedures to follow in the event of MACH TRIM, STAB TRIM, and
horizontal stabilizer trim malfunctions. This AD requires revising the
same Emergency and Abnormal Procedures sections of the AFM to advise
the flightcrew of revised/additional procedures. This AD also requires
revising the Normal section of the AFM to require a review of the
location of certain circuit breakers and a functional check of the
stabilizer trim system. This AD also requires installing circuit
breaker identification collars and provides an optional terminating
action for the requirements of the AD. This AD also removes airplanes
from the applicability of the existing AD. This AD results from reports
of uncommanded horizontal stabilizer trim motion. We are issuing this
AD to ensure that the flightcrew is advised of appropriate procedures
to follow in the event of uncommanded movement or stabilizer trim
runaway. Failure to follow these procedures could result in excessive
uncommanded movement of the horizontal stabilizer trim actuator
[[Page 63220]]
(HSTA) and loss of ability to use trim switches to override uncommanded
movement or yoke disconnect switches to disconnect the HSTA, which
could result in reduction of or loss of pitch control and consequent
reduced controllability of the airplane.
DATES: This AD becomes effective November 14, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of November 14,
2006.
On September 1, 2006 (71 FR 51990, September 1, 2006), the Director
of the Federal Register approved the incorporation by reference of
certain other publications listed in the AD.
We must receive any comments on this AD by December 29, 2006.

SUPPLEMENTARY INFORMATION:
Discussion
On August 29, 2006, the FAA issued AD 2006-18-04, amendment 39-
14742 (71 FR 51990, September 1, 2006). That AD applies to certain
Bombardier Model CL-600-2B16 (CL-604) airplanes and Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes. That AD requires revising
the Emergency Procedures section of the airplane flight manual (AFM) to
advise the flightcrew of additional procedures to follow in the event
of stabilizer trim runaway. For certain airplanes, that AD also
requires revising the Abnormal Procedures section of the AFM to advise
the flightcrew of procedures to follow in the event of MACH TRIM, STAB
TRIM, and horizontal stabilizer trim malfunctions. That AD resulted
from reports of uncommanded horizontal stabilizer trim motion. The
actions specified in that AD are intended to ensure that the flightcrew
is advised of appropriate procedures to follow in the event of
stabilizer trim runaway. Failure to follow these procedures could
result in excessive uncommanded movement of the horizontal stabilizer
trim actuator (HSTA) and loss of ability to use trim switches to
override uncommanded movement or yoke disconnect switches to disconnect
the HSTA, which could result in reduction of or loss of pitch control
and consequent reduced controllability of the airplane.
That AD paralleled Canadian airworthiness directives CF-2006-20,
dated August 22, 2006, and CF-2006-21, dated August 23, 2006.
Actions Since AD Was Issued
Since we issued that AD 2006-18-04, Transport Canada Civil Aviation
(TCCA), which is the airworthiness authority for Canada, issued
Canadian airworthiness directives CF-2006-21R1, dated October 3, 2006,
and CF-2006-20R1, dated October 4, 2006, which supersede Canadian
airworthiness directives CF-2006-21 and CF-2006-20, respectively. The
new Canadian airworthiness directives specify revising the AFM
procedures for stabilizer trim runaway, installing circuit breaker
collars, and introducing trim system preflight tests. The Canadian
airworthiness directives also specify installing a new, improved
horizontal stabilizer trim control unit (HSTCU). The new Canadian
airworthiness directives also revise the affected airplanes by removing
serial numbers (S/Ns) 5666 and subsequent for the Model CL-600-2B16
(CL-604) airplanes and removing S/Ns 8067 and subsequent for Model CL-
600-2B19 (Regional Jet Series 100 & 440) airplanes. Model CL-600-2B16
(CL-604) airplanes, S/Ns 5666 and subsequent, and Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes, S/Ns 8067 and subsequent,
have the new, improved HSTCU installed during production.
In AD 2006-18-04, we stated that we considered that AD interim
action and that the manufacturer was developing service bulletins that
specify replacing HSTCU circuit boards with HSTCU circuit boards having
conformal coating and was exploring other interim measures. The
manufacturer now has developed a replacement and other interim
measures, and we have determined that further rulemaking is indeed
necessary; this AD follows from that determination.
Relevant Service Information
Bombardier has issued the temporary revisions (TRs) specified in
the table below.
Table--TRs
----------------------------------------------------------------------------------------------------------------
For Bombardier Model-- Use-- Dated-- To the--
----------------------------------------------------------------------------------------------------------------
CL-600-2B16 (CL-604) airplanes..... Canadair Challenger TR October 3, 2006............. Canadair Challenger

100 & 440) airplanes. TR RJ/152-5. AFM, CSP A-012.
----------------------------------------------------------------------------------------------------------------
TR 604/21-1 describes revising the Emergency and Abnormal Procedures
sections of the Canadair Challenger CL-604 AFM to advise the flightcrew
of additional procedures to follow in the event of stabilizer trim
runaway and to advise the flightcrew of revised procedures to follow in
the event of MACH TRIM, STAB TRIM, and horizontal stabilizer trim
malfunctions. TR RJ/152-5 describes revising the Emergency and Abnormal
Procedures sections of the Canadair Regional Jet AFM to advise the
flightcrew of revised procedures to follow in the event of stabilizer
trim runaway and in the event of MACH TRIM, STAB TRIM, and horizontal
stabilizer trim malfunctions.
Bombardier has also issued Modification Summary Package
IS601R27410051, Revision C, dated September 29, 2006 (for Model CL-600-
2B19 (Regional Jet Series 100 & 440)
[[Page 63221]]
airplanes). The modification summary package describes procedures for
installing circuit breaker identification collars on certain circuit
breakers.
Bombardier has also issued Alert Service Bulletin A604-27-029,
dated September 28, 2006 (for Model CL-600-2B16 (CL-604) airplanes).
The service bulletin describes procedures for installing circuit
breaker identification collars on certain circuit breakers and for
installing a new, improved HSTCU.
Bombardier has also issued Service Bulletin 601R-27-147, dated
September 28, 2006 (for Model CL-600-2B19 (Regional Jet Series 100 &
440) airplanes). The service bulletin describes procedures for
installing a new, improved HSTCU. The service bulletin refers to Sagem
Service Bulletin HSTCU-27-011, dated September 22, 2006, as an
additional source of service information for doing the installation.
TCCA mandated the service information and issued Canadian
airworthiness directives CF-2006-20R1, dated October 4, 2006, and CF-
2006-21R1, dated October 3, 2006, to ensure the continued airworthiness
of these airplanes in Canada. The Canadian airworthiness directives
also specify to brief the flightcrew to do the following actions prior
to the first flight of the day: Do a review of the location of certain
circuit breakers, and do a functional check of the stabilizer trim
system.
FAA's Determination and Requirements of This AD
These airplane models are manufactured in Canada and are type
certificated 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. Pursuant to this
bilateral airworthiness agreement, TCCA has kept the FAA informed of
the situation described above. We have examined TCCA's findings,
evaluated all pertinent information, and determined that we need to
issue an AD for products of this type design that are certificated for
operation in the United States.
Therefore, we are issuing this AD to supersede AD 2006-18-04. This
new AD retains the requirements of the existing AD and requires
revising the Emergency and Abnormal Procedures sections of the AFM to
advise the flightcrew of additional/revised procedures to follow in the
event of stabilizer trim runaway, which replace AFM revisions required
by the existing AD. This new AD also requires the installation of
circuit breaker identification collars. This AD also requires revising
the Normal section of the AFM to require the flightcrew to review the
location of certain circuit breakers and do a functional check of the
stabilizer trim system prior to the first flight of the day. This new
AD also provides an optional terminating action for the requirements of
this AD. This new AD also removes airplanes from the applicability of
the existing AD.
Interim Action
We consider this AD interim action. We are currently considering
requiring the installation of a new, improved HSTCU, which will
constitute terminating action for the requirements of this AD action.
However, the planned compliance time for the installation of the
modification would allow enough time to provide notice and opportunity
for prior public comment on the merits of the modification.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD; therefore, providing notice and opportunity for public comment
before the AD is issued is impracticable, and good cause exists to make
this AD effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for
public comment; however, we invite you to submit any relevant written
data, views, or arguments regarding this AD. Send your comments to an
address listed in the ADDRESSES section. Include ``Docket No. FAA-2006-
26118; Directorate Identifier 2006-NM-226-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the AD that might
suggest a need to modify it.
We will post all comments we receive, without change, to http://dms.dot.gov
, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact with FAA
personnel concerning this AD. Using the search function of that Web
site, anyone can find and read the comments in any of our dockets,
including the name of the individual who sent the comment (or signed
the comment on behalf of an association, business, labor union, etc.).
You can review the DOT's complete Privacy Act Statement in the Federal
Register published on April 11, 2000 (65 FR 19477-78), or you can visit
http://dms.dot.gov.
Examining the Docket
You may examine the AD docket on the Internet at http://dms.dot.gov
, or in person at the Docket Management Facility office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the DOT
street address stated in the ADDRESSES section. Comments will be
available in the AD docket shortly after the Docket Management System
receives them.
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 have 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 the 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 AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
