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 Reacutegional 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 Reacutegional 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.
