Is AD 2012-5372 a recurring Airworthiness Directive?

Yes — AD 2012-5372 requires a repetitive inspection every 600 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2012-5372 apply to?

AD 2012-5372 applies to Thielert Aircraft Engines Gmbh — models TAE 125-01, TAE 125-02-99, TAE 125. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

We are revising an existing airworthiness directive (AD) for TAE models TAE 125-01 and TAE 125-02-99 reciprocating engines installed on, but not limited to, Diamond Aircraft Industries Model DA 42 airplanes. That AD currently requires initial and repetitive replacements of proportional pressure reducing valves (PPRVs) (also known as propeller control valves). This new AD relaxes the repetitive replacement interval from a 300-hour interval to a 600-hour interval for PPRVs, P/N 05-7212-E002801, on TAE 125-02-99 engine. This AD was prompted by TAE increasing the life of the PPRV, part number (P/N) 05- 7212-E002801, on TAE 125-02-99 engines from 300 to 600 hours. We are issuing this AD to prevent engine in-flight shutdown, possibly resulting in reduced control of the aircraft.

Repetitive inspection. Re-inspect every 600 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 2012-5372 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.

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.
