Airworthiness Directives; Technify Motors GmbH (Type Certificate Previously Held by Thielert Aircraft Engines GmbH) Reciprocating Engines

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Technify Motors GmbH TAE 125-02-99 and TAE 125-02-114 model reciprocating engines. This AD was prompted by a report of a defective turbocharger hose discovered on an airplane during a pre-flight inspection. This AD requires the removal and replacement of the affected turbocharger hose. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2020-27312 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 2020-27312 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.
