Airworthiness Directive 2020-14-07
one-timeAirworthiness Directives; Austro Engine GmbH Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for all Austro Engine GmbH model E4 and E4P diesel piston engines. This AD was prompted by reports of considerable wear of the timing chain and failure of fuel injectors on these engines. This AD requires replacement of the timing chain and fuel injectors on the affected Austro Engine GmbH model E4 and E4P diesel piston engines. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2020-14-07 applies to
Diesel piston engines.
Whether AD 2020-14-07 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:
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.
