Full official abstract

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.
