Federal Register Abstract
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.

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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends part 39 of the Federal Aviation
