SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive, 2013-0032, dated February 18, 2013 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain ATR-GIE 
Avions de Transport R[eacute]gional Model ATR42-300 and -500 airplanes 
and Model ATR72-202 and -212A airplanes. The MCAI states:

    During the investigation performed on a failed dual distributor 
valve (DDV) shipped to the DDV manufacturer, a non-conformity of 
crimping on an internal valve has been detected by the DDV 
manufacturer. This defective crimping creates a lack of tightness 
that prevents the complete deflation of the related de-icing boot 
chamber during de-icing cycles.
    A batch of serialized DDV, potentially affected with the same 
manufacturing discrepancy, has been identified by the DDV 
manufacturer.
    This condition, if not detected and corrected, may affect the 
efficiency of the pneumatic de-icing system, which could reduce 
flight safety in icing conditions.
    For the reasons described above, this AD requires a one-time 
inspection of each DDV to identify the serial number (s/n) and 
replacement of the non-conforming DDV units.
    The affected DDV units installed on aeroplanes and those 
delivered as spares have been retraced by ATR and all non-installed 
spare units have been quarantined, which is why this AD only applies 
to specific MSN [manufacturer serial number] aeroplanes.

You may examine the MCAI on the internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2017-1170.

Related Service Information Under 1 CFR Part 51

    Avions de Transport R[eacute]gional has issued the following 
service information:
     ATR Service Bulletin ATR42-30-0080, Revision 02, dated 
March 26, 2013.
     ATR Service Bulletin ATR42-30-0081, Revision 02, dated 
March 26, 2013.
     ATR Service Bulletin ATR72-30-1049, Revision 03, dated 
March 26, 2013.
     ATR Service Bulletin ATR72-30-1050, Revision 03, dated 
March 26, 2013.
    This service information describes procedures for identifying and 
replacing affected DDVs. These documents are distinct since they apply 
to different airplane models. 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 of this AD.

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 these 
same type designs.

FAA's Determination of the Effective Date

    There are currently no domestic operators of this product. 
Therefore, we find good cause that notice and opportunity for prior 
public comment are unnecessary. In addition, for the reason(s) stated 
above, we find that good cause exists for making this amendment 
effective in less 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-2017-1170; Product 
Identifier 2013-NM-054-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 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. If 
an affected airplane is imported and placed on the U.S. Register in the 
future, we provide the following cost estimates to comply with this AD. 
We estimate that it will take about 84 work-hours per product to comply 
with the basic requirements of this AD. The average labor rate is $85 
per work-hour. Required parts will cost about $12,000 per product. 
Based on these figures, we estimate the cost of this AD to be $19,140 
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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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:

[[Page 59965]]

    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.
