Airworthiness Directives; Thielert Aircraft Engines GmbH (TAE) Model TAE 125-02-99 Engines

What this AD requires

This document publishes in the Federal Register an amendment adopting emergency airworthiness directive (AD) 2008-06-52 that was sent previously to all known U.S. owners and operators of certain TAE Model TAE 125-02-99 engines. This AD requires, before further flight, replacing the high-pressure fuel line and installing a high-pressure fuel line support. This AD results from reports of in-flight engine shutdown incidents on airplanes equipped with TAE 125-02-99 engines. We are issuing this AD to prevent an in-flight engine shutdown or engine fire due to a cracked fuel line.

Serial-conditional — narrows to serials 02-02-1500–02-02-2279.

Whether AD 2008-06-52 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2008-06-52 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.
