Airworthiness Directives; Austro Engine GmbH Engines

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2018-07-16 for all Austro Engine GmbH model E4 and E4P diesel piston engines. AD 2018-07-16 required initial and repetitive replacement of the waste gate controller and the control rod circlip. This AD retains the requirements of AD 2018-07-16 and requires engine modification by installing a waste gate control-rod fail-safe bridge and new spring- loaded circlip that terminates the initial and repetitive replacement requirements of AD 2018-07-16. This AD was prompted by the development of a modification of the waste gate control rod by adding a fail-safe bridge and spring-loaded circlip. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 2020-22-14 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2020-22-14 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
