SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the aviation 
authority for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0144R1, dated June 10 2014; corrected June 
11, 2014 (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 ATR 42-500 airplanes and Model ATR 72-212A airplanes. The MCAI 
states:

    Damage of an engine fire extinguishing pipe was reported on an 
in-service ATR 72-212A aeroplane. The damage was induced by chafing 
between the engine fire extinguishing pipe and a fastener assembly 
installed between flap arm and hinge flap at rib 4 during flaps 
extension to the 30 degrees position. The subsequent investigation 
also determined that the chafing occurred as a result of an 
incorrect (back to front) installation of the pipe.
    This condition, if not detected and corrected, could lead to 
damage of the fire extinguishing pipe, possibly generating a leak, 
leading to loss of available extinguishing agent and resulting in 
reduced capability to extinguish an engine fire.
    To address this potential unsafe condition, ATR issued Service 
Bulletins (SB) ATR42-26-0031 and ATR72-26-1027 to provide inspection 
instructions, as applicable to aeroplane model.
    For the reasons described above, this [EASA] AD requires a one-
time [general] visual inspection [for damage] of the affected area 
[and incorrect pipe installation] and, depending on findings, 
accomplishment of applicable corrective actions.

Damaged pipes are defined as pipes that have wear due to chafing 
without evidence of cracking. Corrective actions include replacing 
damaged pipes, ensuring correct alignment, applying protective sealant 
and corrosion inhibiting compound, replacing damaged fasteners with new 
fasteners, and repairing flap arms and flap hinges. You may examine the 
MCAI on the internet at http://www.regulations.gov by searching for and 
locating Docket No. FAA-2017-1178.

Related Service Information Under 1 CFR Part 51

    ATR has issued the following service information.
     ATR Service Bulletin ATR42-26-0031, dated April 30, 2014. 
This service information describes procedures for inspecting for damage 
and incorrect installation of the left-hand and right-hand engine fire 
extinguishing pipes, and corrective actions.
     ATR Service Bulletin ATR72-26-1027, dated April 30, 2014. 
This service information describes procedures for inspecting for damage 
and incorrect installation of the left-hand and right-

[[Page 210]]

hand engine fire extinguishing pipes, and corrective actions.
    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 the same 
type design.

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 reasons 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-2017-1178; Product 
Identifier 2014-NM-144-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 U.S.-registered airplanes. 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 2 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 $0 per product. Based on 
these figures, we estimate the cost of this AD will be $170 per 
product.
    We also estimate that any necessary follow-on actions will take 
about 16 work-hours and require parts costing $1,360, for a cost of 
$2,720 per product. We have no way of determining the number of 
aircraft that might need these actions.

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:
    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.
