Airworthiness Directives; Continental Aerospace Technologies GmbH Reciprocating Engines

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Continental Aerospace Technologies GmbH TAE 125-02-99 and TAE 125-02-114 model reciprocating engines. This AD was prompted by manufacturer reports of fractured main bearing studs. This AD requires the removal and replacement of certain main bearing studs. The FAA is issuing this AD to address the unsafe condition on these products.

MakesContinental Aerospace Technologies Gmbh
ModelsTAE 125-02-99, TAE 125-02-114, TAE 125

Applies only to engines with an engine serial number (S/N) identified in Continental Aerospace Technologies GmbH Service Bulletin CG 125-1027 P1, Revision 1, dated May 28, 2021.

Whether AD 2023-02154 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 2023-02154 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.
