Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD 2016-0144, dated July 19, 2016 (corrected July 25, 2016) (referred
to hereinafter as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
Due to a quality escape in the manufacturing process of certain
floats, Part Number (P/N) 861185, a partial separation of the float
outer skin may occur during engine operations. Separated particles
could lead to a restriction of the jets in the carburetor, possibly
reducing or blocking the fuel supply to the affected cylinder.
This condition, if not detected and corrected, could lead to in-
flight engine shutdown and forced landing, possibly resulting in
damage to the aeroplane and injury to the occupants.
You may obtain further information by examining the MCAI in the AD
docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for
and locating Docket No. FAA-2016-9103.
Related Service Information Under 1 CFR Part 51
BRP-Powertrain GmbH & Co KG has issued Alert Service Bulletin ASB-
912-069R1/ASB-914-051R1 (one document), Revision 1, dated July 22,
2016. The service information describes procedures for removal and
replacement of the carburetor float. 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.
FAA's Determination and Requirements of This AD
This product has been approved by the aviation authority of
Austria, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the European Community, EASA has
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 EASA and determined the unsafe
condition exists and is likely to exist or develop on other products of
the same type design. This AD requires removal and replacement of the
affected carburetor float.
FAA's Determination of the Effective Date
No domestic operators use this product. Therefore, we find that
notice and opportunity for prior public comment are unnecessary and
that good cause exists for making this amendment effective in less than
30 days.
Costs of Compliance
We estimate that this AD affects 0 engines installed on aircraft of
U.S. registry. We also estimate that it will take about 4 hours per
engine to search maintenance records, disassemble the carburetor, and
replace the float. The average labor rate is $85 per hour. Based on
these figures, we estimate the cost of this AD on U.S. operators to be
$0.
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 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 to the extent
that it justifies making a regulatory distinction, 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.
