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.

----------------------------------------------------------------------------------------------------------------

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.

the following new AD:

2006-22-06 Bombardier, Inc. (Formerly Canadair): Docket No. FAA-
2006-26118; Directorate Identifier 2006-NM-226-AD; Amendment 39-
14803.

Effective Date

    (a) This AD becomes effective November 14, 2006.

Affected ADs

    (b) This AD supersedes AD 2006-18-04.

Applicability

    (c) This AD applies to Bombardier Model CL-600-2B16 (CL-604) 
airplanes, serial numbers 5301 through 5665 inclusive; and Model CL-
600-2B19 (Regional Jet Series 100 & 440) airplanes, serial numbers 
7003 through 7990 inclusive and 8000 through 8066 inclusive;

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 (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.
