Airworthiness Directives; BRP-Powertrain GmbH & Co KG 
Reciprocating Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
BRP-Powertrain GmbH & Co KG Rotax 912 F2, 912 F3, 912 F4, 912 S2, 912 
S3, 912 S4, 914 F2, 914 F3, and 914 F4 reciprocating engines. This AD 
requires replacement of any affected carburetor float with a float that 
is eligible for installation. This AD was prompted by a report of a 
quality escape in the manufacturing of the affected floats. We are 
issuing this AD to prevent failure of the carburetor float, failure of 
the engine, in-flight shutdown, and loss of the airplane.

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 http://www.regulations.gov 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.
