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 AD
2013-0010, January 14, 2013 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Fokker Services B.V. Model F28 Mark 0070
and 0100. The MCAI states:
Recently, a Tay 620 engine multiple fan blade release event
occurred on an F28 Mk. 0070 aeroplane. As a result, low energy fan
blade fragments exited the engine by penetrating the engine nose
cowl. Although the investigation is still on-going, one of the
findings was an incorrect adjustment of the (emergency) maximum
reverse thrust stop. Consequently, attempts to select (emergency)
maximum reverse thrust led to stabilized engine operation in an N1
speed range that, in combination with other contributing factors,
may have caused high fan blade stresses due to flutter.
This condition, if not detected and corrected, could lead to
further cases of multiple fan blade release, possibly resulting in
damage to the aeroplane and injury to occupants.
For the reasons described above, this [EASA] AD requires a one-
time inspection to verify the correct adjustment of the (emergency)
maximum reverse thrust stop position and, if an incorrect adjustment
is found, accomplishment of applicable corrective action(s). To
support the investigation, this [EASA] AD also requires that all
findings are reported to Fokker Services.
You may examine the MCAI on the internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2017-
1183.

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. 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, 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-2017-1183; Product
Identifier 2013-NM-022-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 U.S.-registered airplanes. This AD
requires contacting the FAA to obtain instructions for addressing the
unsafe condition, and doing the actions specified in those
instructions. Based on the actions specified in the MCAI AD, we are
providing the following cost estimates for an affected airplane that is
placed on the U.S. Register in the future:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Inspection................................. 6 work-hours x $85 per hour = $510. $0 $510
Reporting.................................. 1 work-hour x $85 per hour = $85... 0 85
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this AD.
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.
