Airworthiness Directives; Austro Engine GmbH Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding airworthiness directive (AD) 2013-14-08 for 
all Austro Engine GmbH model E4 engines. AD 2013-14-08 required 
removing from service certain part number (P/N) waste gate controllers. 
This AD requires removing certain additional P/N waste gate controllers 
from service. This AD was prompted by several reports of power loss 
events due to fracture of the waste gate controller lever. We are 
issuing this AD to prevent failure of the waste gate controller lever, 
which could lead to damage to one or more engines, loss of thrust 
control, and damage to the airplane.

DATES: This AD is effective June 3, 2014.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2013-14-08, Amendment 39-17513 (78 FR 42677, 
July 17, 2013), (``AD 2013-14-08''). AD 2013-14-08 applied to the 
specified products. The NPRM published in the Federal Register on 
January 10, 2014 (79 FR 1774). The NPRM proposed to continue to require 
removal from service of certain P/N waste gate controllers. The NPRM 
also proposed that, based on additional in-service failures, additional 
P/N waste gate controllers no longer be eligible for installation.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 1774, January 10, 
2014).

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed.

Costs of Compliance

    We estimate that this AD affects 128 engines installed on airplanes 
of U.S. registry. We also estimate that it will take about 0.5 hours 
per engine to comply with this AD. The average labor rate is $85 per 
hour. Required parts cost about $231 per engine. Based on these 
figures, we estimate the total cost of this AD to U.S. operators to be 
$35,008.

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

    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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.

    Accordingly, under the authority delegated to me by the
