Airworthiness Directives; MT-Propeller Entwicklung GmbH Propellers

What this AD requires

The FAA is superseding an existing airworthiness directive (AD) for certain MT-Propeller Entwicklung GmbH variable pitch and fixed pitch propellers manufactured before 1995, which had not been overhauled since April 1994. That AD currently requires overhauling the propeller blades and performing initial and repetitive visual inspections of affected propeller blades. That AD also requires removing all propeller blades from service with damaged erosion sheath bonding or loose erosion sheaths and installing any missing or damaged polyurethane protective strips. This AD requires the same actions. This AD results from the need to clarify the population of affected propellers previously listed in AD 2006-05-05. We are issuing this AD to prevent erosion sheath separation leading to damage of the airplane.

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

Applies to propellers manufactured before 1995 that have not been overhauled since April 1994. May be installed on, but not limited to, Apex ATL, Apex DR400, EADS Socata Rallye, Extra EA-300, Piper PA-46, Rene Fournier RF4, Sukhoi SU-26/SU-29/SU-31, Yakovlev YAK-52/YAK-54/YAK-55, and Technoavia SM-92 airplanes.

Whether AD 2007-26-13 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 2007-26-13 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.
