Thielert Aircraft Engines GmbH Reciprocating Engines
This AD applies to Thielert Aircraft Engines GmbH models TAE 125-01, TAE 125-02-99, and TAE 125-02-114 reciprocating engines installed in, but not limited to, Cessna 172 and (Reims-built) F172 series (European Aviation Safety Agency (EASA) Supplemental Type Certificate (STC) No. EASA.A.S.01527); Piper PA-28 series (EASA STC No. EASA.A.S. 01632); APEX (Robin) DR 400 series (EASA STC No. A.S.01380); and Diamond Aircraft Industries Models DA 40, DA 42, and DA 42M NG airplanes.
We are superseding an existing airworthiness directive (AD) for all Thielert Aircraft Engines GmbH models TAE 125-01, TAE 125-02- 99, and TAE 125-02-114 reciprocating engines. That AD currently requires installation of full-authority digital electronic control (FADEC) software version 2.91. This new AD requires removing all software mapping versions prior to 292, 301, or 302, applicable to the TAE engine model. This AD was prompted by reports of possible power loss on airplanes equipped with TAE 125 engines. We are issuing this AD to prevent engine power loss or in-flight shutdown, resulting in reduced control of or damage to the airplane.
Unless already done, do the following. Within 55 flight hours or within 3 months of the effective date of the AD, or during the next scheduled maintenance, whichever occurs first, remove all full-authority digital electronic control (FADEC) software prior to versions 292, 301, and 302. Tables 1, 2, and 3 to paragraph (e) provide the software mapping and respective part numbers for software versions 292, 301, and 302, installed on the TAE 125-01, TAE 125-02-99, and TAE-125-02-114 engines, respectively.
