Airworthiness Directive · Amendment 39-17513 · Austro Engine GmbH Engines
Austro Engine GmbH Engines
Superseded. A later AD replaced this one: AD 2014-08-10. Comply with the one in force.
This AD applies to all Austro Engine GmbH model E4 engines, with a waste gate controller, part number (P/N) E4A-41-120-000 Rev. 050, or lower revision, or a waste gate controller, P/N E4B-41-120-000 Rev. 000, installed.
We are adopting a new airworthiness directive (AD) for all Austro Engine GmbH model E4 engines. This AD requires removing from service certain part number waste gate controllers. 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 engine power loss or in-flight shutdown, which could result in loss of control and damage to the airplane.
(1) Unless already done, during the next engine maintenance, or within 110 flight hours, or within three months after the effective date of this AD, whichever occurs first, do the following.
(2) Remove from service waste gate controllers, P/N E4A-41-120-000 Rev. 050, or lower revision, and waste gate controllers, P/N E4B-41-120-000 Rev. 000.
After the effective date of this AD, do not install any waste gate controller, P/N E4A-41-120-000 Rev. 050, or lower revision, or waste gate controller, P/N E4B-41-120-000 Rev. 000, onto any engine.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
