DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2011-1299; Directorate Identifier 2011-NE-40-AD; 
Amendment 39-16878; AD 2011-25-02]
RIN 2120-AA64


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 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 
results from mandatory continuing airworthiness information (MCAI) 
issued by an aviation authority of another country to identify and 
correct an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as:

    During a production process review, a deviation in the 
manufacturing process of certain part number (P/N) 888164 
crankshafts has been detected, which may have resulted in a latent 
defect. This condition, if not corrected, could lead to crack 
formation on the power takeoff side of the crankshaft journal, 
possibly resulting in failure of the crankshaft support bearing, in-
flight engine shutdown and forced landing, damage to the aeroplane 
and injury to the occupants.

    We are issuing this AD to prevent in-flight failure of the engine 
and forced landing.

DATES: This AD becomes effective December 22, 2011.
    We must receive comments on this AD by January 6, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of BRP-Powertrain GmbH & Co. KG, Rotax Aircraft Engines, 
Mandatory Alert Service Bulletins (ASB) Nos. ASB-912-059 and ASB 914-

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 2011-0222-E, dated November 15, 2011 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    During a production process review, a deviation in the 
manufacturing process of certain part number (P/N) 888164 
crankshafts has been detected, which may have resulted in a latent 
defect. This condition, if not corrected, could lead to crack 
formation on the power takeoff side of the crankshaft journal, 
possibly resulting in failure of the crankshaft support bearing, in-
flight engine shutdown and forced landing, damage to the aeroplane 
and injury to the occupants.

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

Relevant Service Information

    We reviewed BRP-Powertrain GmbH & Co. KG, Rotax Aircraft Engines, 
Mandatory ASB Nos. ASB-912-059 and ASB 914-042 (combined in one 
document), dated November 15, 2011. 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.

Differences Between the AD and the MCAI or Service Information

    None.

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 of 
the short compliance

[[Page 76294]]

time of 4 operating hours, and the risk to single-engine airplanes 
affected. 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-2011-1299; Directorate 
Identifier 2011-NE-40-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.
