AD 2011-07-09 Airworthiness Directives; Thielert Aircraft Engines GmbH Models TAE 125-01, TAE 125-02-99, and TAE 125-02-114 Reciprocating Engines

Makes named: thielert. Models named: DA 40, DA 42, DA 42M NG. Read the applicability below — it usually turns on serial or part numbers too.

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) 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. Reason (d) This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. We are issuing this AD to prevent engine in-flight shutdown or power loss, possibly resulting in reduced control of the airplane.

Unless already done, do the following actions. (1) Within 110 flight hours after the effective date of the AD or during next maintenance, whichever occurs first, install full-authority digital electronic control (FADEC) software version 2.91. (2) Guidance on FADEC software installation can be found in the following: (i) For TAE 125-01 engines, Operation & Maintenance Manual OM-02-01, Version 3, Revision 15. (ii) For TAE 125-02-99 and TAE 125-02-114 engines, Operation & Maintenance Manual OM-02-02, Version 2, Revision 1. Prohibition of FADEC Software Earlier Versions (f) Once FADEC software version 2.91 is installed, do not install any earlier version of FADEC software. FAA AD Differences (g) EASA AD 2010-0137 permits installation of earlier FADEC software versions, once version 2.91 is installed. This AD does not. (h) EASA AD 2010-0137 requires compliance within 110 flight hours after the effective date of the AD or during next maintenance, whichever occurs first, but no later than 6 months after the effective date of the AD. This AD requires compliance within 110 flight hours after the effective date of the AD or during next maintenance, whichever occurs first. Alternative Methods of Compliance (AMOCS) (i) The Manager, Engine Certification Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Related Information (j) Refer to EASA AD 2010-0137, dated June 30, 2010, for related information.
