Airworthiness Directives; Austro Engine GmbH Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Austro Engine GmbH model E4 engines. This proposed AD was prompted by 
reports of several power loss events due to fracture of the waste gate 
controller lever. This proposed AD would require removing from service 
certain part number (P/N) waste gate controllers. We are proposing this 
AD to prevent engine power loss or in-flight shutdown, which could 
result in loss of control and damage to the airplane.

DATES: We must receive comments on this proposed AD by May 28, 2013.

ADDRESSES: You may send comments by any of the following methods:

comments electronically.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2013-0025, dated February 6, 2013 (referred to 
herein after as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Several power loss events have been reported on Austro E4 
engines, due to fracture of the waste gate controller lever. This 
condition, if not corrected, could lead to further cases of power 
loss events, possibly

[[Page 18921]]

resulting in forced landing, damage to the aeroplane and injury to 
occupants.

We are proposing this AD to prevent engine power loss or in-flight 
shutdown, which could result in loss of control and damage to the 
airplane. You may obtain further information by examining the MCAI in 
the AD docket.

Relevant Service Information

    Austro Engine GmbH has issued Mandatory Service Bulletin No. MSB-
E4-007/3, Revision 3, dated November 28, 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 Proposed 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 Austria, EASA has notified us of the 
unsafe condition described in the MCAI and service information 
referenced above. We are proposing 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 proposed AD would require removing from service waste gate 
controllers, P/N E4A-41-120-000 Rev. 050 or lower, and waste gate 
controllers, P/N E4B-41-120-000 Rev. 000 during the next engine 
maintenance, or within 110 flight hours or three months after the 
effective date of the AD, whichever occurs first.

Costs of Compliance

    We estimate that this proposed AD affects 72 engines installed on 
airplanes of U.S. registry. We also estimate that it would take about 
one hour per engine to comply with this proposed AD. The average labor 
rate is $85 per hour. Based on these figures, we estimate the cost of 
the proposed AD on U.S. operators to be $6,120. Our cost estimate is 
exclusive of possible warranty coverage.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
