SUMMARY: We are adopting a new airworthiness directive (AD) for BRP-
Powertrain GmbH & Co KG Rotax 912 F2; 912 F3; 912 F4; 912 S2; 912 S3; 
and 912 S4 reciprocating engines. This AD requires replacing the 
pressure side fuel hose on certain fuel pumps and inspecting the 
carburetors connected to those fuel pumps for contamination within 5 
flight hours after the effective date of this AD. This AD was prompted 
by reports of fuel pumps having pressure side fuel hoses not meeting 
the design specification. We are issuing this AD to prevent pressure 
side fuel hose deterioration and contamination of the carburetor, which 
could result in an in-flight engine shutdown, forced landing and damage 
to the airplane.

SUPPLEMENTARY INFORMATION: 

[[Page 51463]]

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2012-0097-E, dated May 31, 2012, and AD 2012-0097R1, dated June 1, 
2012 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    Reports from the field confirmed a non-compliance of the 
pressure side fuel hoses installed on certain P/N 893114 fuel pumps, 
which may have resulted in a latent defect on a limited number of 
engines. The affected hoses may not be fuel resistant in accordance 
with the specification. This condition, if not corrected, could lead 
to detachment of particles from the fuel hose and irregularities in 
the carburetor function, possibly resulting in in-flight engine 
shutdown, and forced landing, damage to the aeroplane and injury to 
occupants.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    BRP-Powertrain GmbH & Co KG has issued Alert Service Bulletin No. 
ASB-912-061R1, dated May 31, 2012. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

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 replacing the pressure side fuel 
hose on certain fuel pumps and inspecting the carburetors connected to 
those fuel pumps for contamination within 5 flight hours after the 
effective date of the AD.

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 the 
compliance time in this AD is within 5 flight hours after the effective 
date of the AD. Therefore, we determined that notice and opportunity 
for public comment before issuing this AD are impracticable and that 
good cause exists for making this amendment effective in fewer 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-2012-0603; Directorate 
Identifier 2012-NE-17-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 http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact 
with FAA personnel concerning this AD. Using the search function of the 
Web site, anyone can find and read the comments in any of our dockets, 
including, if provided, the name of the individual who sent the comment 
(or signed the comment on behalf of an association, business, labor 
union, etc.). You may review the DOT's complete Privacy Act Statement 
in the Federal Register published on April 11, 2000 (65 FR 19477-78).

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); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
