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); VerDate Mar<15>2010 13:48 Jul 24, 2013 Jkt 229001 List of Subjects in 14 CFR Part 39 (c) Applicability This AD applies to all airplanes specified in paragraphs (c)(1) through (c)(4) of this AD, certificated in any category.

In that final rule, which became effective July 15, 2013, the FAA revised the aeronautical experience requirements for an airline transport pilot (ATP) certificate in § 61.159(a) by adding paragraph (a)(3) which requires pilots to obtain 50 hours in the class of airplane for the ATP certificate sought and by revising former paragraph (a)(5) to permit pilots to credit time in a flight simulation training device (FSTD) accomplished in approved training programs under parts 121, 135, and 141 toward the aeronautical experience requirements for the ATP certificate. Under the prior rule, only FSTD time accomplished as part of an approved training course in part 142 could be credited. RIN 2120–AJ67 Correction Pilot Certification and Qualification Requirements for Air Carrier Operations; Correction In the amendatory language, the FAA mistakenly directed that redesignated paragraph (a)(5) be revised to permit the FSTD time in parts 121, 135, and 141 to be credited. In fact, because the final rule added new paragraph (a)(3), the amendatory language should have directed that redesignated paragraph (a)(6) should be revised.

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.

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

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 https://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

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.

(d) Subject

    Air Transport Association (ATA) of America Code 2720, Rudder 
Control System.

(e) Reason

    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.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Airplane Flight Manual (AFM) Revision

    Within 30 days after the effective date of this AD, revise the 
Emergency Procedures Section and the Limitations Section of the 
Bombardier AFM to incorporate the ``Uncommanded Yaw Motion'' 
procedure specified in paragraphs (g)(1) through (g)(3) of this AD, 
as applicable.
