Airworthiness Directive · Amendment 39-19381 · Austro Engine GmbH Engines
Austro Engine GmbH Engines
Superseded. A later AD replaced this one: AD 2020-15-05. Comply with the one in force.
This AD applies to Austro Engine GmbH E4, E4P.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
We are adopting a new airworthiness directive (AD) for certain Austro Engine GmbH model E4 engines and for all model E4P engines. This AD was prompted by reports of considerable wear on the timing chain on these engines. This AD requires replacement of the timing chain and amending certain airplane flight manuals to limit the use of windmill restarts. We are issuing this AD to address the unsafe condition on these products.
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.
