SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD No.: 2016-0091, dated May 16, 2016 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
Cracks were found in the bonded joint of the rear horizontal
stabiliser frame of G 115E aeroplanes.
This condition, if not detected and corrected, may lead to crack
propagation into primary structural elements, with detrimental
effect on the structural integrity of the aeroplane.
To address this potential unsafe condition, GROB issued Service
Bulletin (SB) MSB1078-200 (hereafter referred to as ``the SB'' in
this AD) to provide instructions for inspections and corrective
action.
For the reason described above, this AD requires repetitive
inspections of the rear horizontal stabilizer frame and modification
of the affected structure.

7057.
Related Service Information Under 1 CFR Part 51
GROB Aircraft AG has issued Service Bulletin No. MSB1078-200, dated
February 25, 2016. The service information describes procedures for
repetitive inspections of the rear horizontal stabilizer frame for
cracks and procedures for repair if necessary. 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 the AD.
FAA's Determination and Requirements of the 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 this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are issuing this AD because we
evaluated all information provided by the State of Design Authority 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
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because there
are no airplanes currently on the U.S. registry and thus, does not have
any impact upon the public. Therefore, we find that notice and
opportunity for prior public comment 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-2016-7057; Directorate
Identifier 2016-CE-017-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 because of
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
We estimate that this AD will affect 0 products of U.S. registry.
We also estimate that it would 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.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $0, or $170 per product.
In addition, we estimate that any necessary follow-on actions would
take about 15 work-hours and require parts costing $60, for a cost of
$1,335 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.
