## Summary

We propose to supersede airworthiness directive (AD) 2013-14- 08 that applies to all Austro Engine GmbH model E4 engines. AD 2013-14- 08 requires removing from service certain part number (P/N) waste gate controllers. Since we issued AD 2013-14-08 we received several reports of power loss events due to fracture of the waste gate controller lever. This proposed AD would require removing certain P/N waste gate controllers from service. We are proposing 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.
