Abstract
The FAA is superseding Airworthiness Directive (AD) 2018-18-02 for certain Austro Engine GmbH model E4 engines and all Austro Engine GmbH model E4P engines. AD 2018-18-02 required replacement of the timing chain and amending certain airplane flight manuals (AFMs) to limit the use of windmill restarts. This AD requires amendment of certain existing AFMs to limit the use of windmill restarts and removes the timing chain replacement requirement in AD 2018-18-02. This AD was prompted by reports of considerable wear of the timing chain on the affected engines. The FAA is issuing this AD to address the unsafe condition on these products.
