SUPPLEMENTARY INFORMATION: 

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2015-11, dated June 9, 2015 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for all Bombardier, Inc., Model CL-600-2E25 (Regional 
Jet Series 1000) airplanes. The MCAI states:

    Two in-service incidents have been reported on CL-600-2C10 
aeroplanes regarding a loss of all air data information in the 
cockpit. The air data information was recovered as the aeroplane 
descended to lower altitudes. An investigation determined that the 
root cause in both events was high altitude icing (ice crystal 
contamination). If not addressed, this condition may affect 
continued safe flight.
    Due to similarities in the air data systems, such events could 
happen on all Bombardier CRJ models, CL-600-2B19, CL-600-2C10, CL-
600-2D15, CL-600-2D24 and CL-600-2E25. Therefore, the corrective 
actions for these models will be mandated once their respective 
Airplane Flight Manual (AFM) revisions become available.
    This [Canadian] AD mandates the incorporation of AFM procedures 
to guide the crew to stabilize the aeroplanes airspeed and attitude 
for continued safe flight.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0558.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc., has issued Section 03-19, ``Unreliable 
Airspeed,'' of Chapter 3, ``Emergency Procedures,'' in the Bombardier 
CRJ Series Regional Jet Model CL-600-2E25 (Series 1000) AFM, Revision 
9, dated February 13, 2015. The service information describes 
procedures to stabilize the airplane's airspeed and attitude. This 
service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

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 this same 
type design.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

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-2017-0558; Directorate 
Identifier 2015-NM-133-AD'' at the beginning of your comments.

[[Page 27976]]

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 based on 
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

    Currently, there are no affected airplanes on the U.S. Register. 
However, if an affected airplane is imported and placed on the U.S. 
Register in the future, the required actions would take about 1 work-
hour per product to comply with the basic requirements of this AD. The 
average labor rate is $85 per work-hour. Based on these figures, we 
estimate the cost of this AD to be $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 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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2017-12-15 Bombardier, Inc.: Amendment 39-18930; Docket No. FAA-
2017-0558; Directorate Identifier 2015-NM-133-AD.

(a) Effective Date

    This AD becomes effective July 5, 2017.

(b) Affected ADs
