Full official 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.
