14 CFR Part 39
[Docket No. FAA-2013-0623; Directorate Identifier 2013-NM-109-AD;
Amendment 39-17516; AD 2013-14-11]

Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440), CL-
600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional
Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes.
This AD requires revising the airplane flight manual (AFM) by
incorporating an emergency procedure for uncommanded yaw motion. This
AD was prompted by reports of airplanes experiencing uncommanded rudder
movements while in flight. We are issuing this AD to advise the
flightcrew of procedures to address a possible failure of the voltage
regulator inside the yaw damper actuator that could lead to uncommanded
yaw movement and consequent loss of the ability to control the
airplane.
DATES: This AD becomes effective August 9, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of August 9,
2013.
We must receive comments on this AD by September 9, 2013.
ADDRESSES: You may send comments by any of the following methods:

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-13, dated May 28, 2013 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for the specified products. The MCAI states:
There have been several reported incidents where Bombardier Regional
Jet aeroplanes experienced in flight uncommanded rudder movements.
Investigation revealed that a failure of the voltage regulator
inside the yaw damper actuator could lead to uncommanded yaw
movement. If not corrected, this condition could lead to the loss of
the * * * [ability to control the] aeroplane.
This [TCCA] AD mandates the introduction of an emergency procedure
to the Aeroplane Flight Manual (AFM) to address the above mentioned
unsafe condition.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Bombardier Inc., has issued the following emergency procedures for
the AFMs:
For Bombardier, Inc. Model CL-600-2B19 (Regional Jet
Series 100 & 440) airplanes: Procedure 1., Automatic Flight Control
System (AFCS), of Section 03-06, Emergency Procedures--Automatic Flight
Control System, of Chapter 3, Emergency Procedures, in Volume 1 of the
Bombardier CRJ Series Regional Jet Model CL-600-2B19 AFM, CSP A-012,
Revision 61, dated April 2, 2013.
For Bombardier, Inc. Model CL-600-2C10 (Regional Jet
Series 700, 701, & 702) airplanes: Procedure 1., Automatic Flight
Control System (AFCS), of Section 03-06, Emergency Procedures--
Automatic Flight Control System, of Chapter 3, Emergency Procedures, in
Volume 1 of the Bombardier CRJ Series Regional Jet Model CL-600-2C10
AFM, CSP B-012, Revision 11, dated February 14, 2013.
For Bombardier, Inc. Model CL-600-2D15 (Regional Jet
Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes:
Procedure 1., Automatic Flight Control System (AFCS), of Section 03-06,
Emergency Procedures--Automatic Flight Control System, of Chapter 3,
Emergency Procedures, in Volume 1 of the Bombardier CRJ Series Regional
Jet Model CL-600-2D24 and Model CL-600-2D15 AFM, CSP C-012, Revision 7,
dated February 14, 2013.
FAA's Determination and Requirements of This AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are issuing this AD because we
evaluated all pertinent information and determined the unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
[[Page 44872]]
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because of a
possible failure of the voltage regulator inside the yaw damper
actuator that could lead to uncommanded yaw movement, which could lead
to the loss of the ability to control the airplane. Therefore, we
determined that notice and opportunity for public comment before
issuing this AD are impracticable and that good cause exists for making
this amendment effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2013-0623; Directorate
Identifier 2013-NM-109-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
Costs of Compliance
We estimate that this AD affects 929 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.

Revision.......................... 1 work-hour x $85 per $0 $85 $78,965

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 that 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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
