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 2012-0192, dated September 21, 2012 (corrected
September 24, 2012) (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
ATR72-212A airplanes. The MCAI states:
Several cases of engine shock mount pick-up fitting with crack
or failure have been reported, always on engine Left Hand (LH) aft
side attachment. Prompted by those reports, improved Part Number (P/
N) S54210394200 (Barry Control P/N 94423-05) fittings (machined
radius modification) have been introduced in production, having
serial number (s/n) 2451 and higher. No crack has been reported on
aeroplanes equipped with those improved fittings.
Two recent cases of failed cone bolt have been reported on ATR
72-212A aeroplanes, both on engine Right Hand (RH) aft side
isolator.
An aft side attachment pick-up fitting failure associated to a
cone bolt failure, if not detected and corrected, could reduce the
structural integrity of the concerned engine nacelle, possibly
resulting in detachment of the engine and consequent reduced control
of the aeroplane.
For the reasons described above, this [EASA] AD requires a one-
time [detailed] inspection [for cracks] of the shock mount pick-up
fittings and cone bolts and, depending on findings, accomplishment
of applicable repair. This AD also requires replacement of all LH
shock mount pick-up fitting P/N S54210394200 having a s/n lower than
2451.

0497.
Related Service Information Under 1 CFR Part 51
ATR-GIE Avions de Transport R[eacute]gional (ATR) has issued the
following service information. The service information describes
procedures for a detailed visual inspection of the engine shock mounts.
The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
<bullet> ATR ATR72 airplane maintenance manual (AMM) Job
Instruction Card 54-11-61 DVI 10000, Detailed Visual Inspection of
Forward Engine Mount, dated March 1, 2012.
<bullet> ATR ATR72 AMM Job Instruction Card 71-20-00 DVI 10000,
Detailled (sic) Visual Inspec[tion] of Engine Shockmounts, dated March
1, 2012.
This service information is reasonably available; see ADDRESSES for
ways to access this service information.
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
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-2015-0497; Directorate
Identifier 2012-NM-192-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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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,
[[Page 21641]]
if an affected airplane is imported and placed on the U.S. Register in
the future, we estimate that it will take about 3 work-hours 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 on U.S. operators to be $255 per product.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave., SW., Washington, DC 20591, ATTN: Information
Collection Clearance Officer, AES-200.
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.
