Thielert Aircraft Engines GmbH (TAE) Model TAE 125-02-99 Reciprocating Engines
This AD applies to Thielert Aircraft Engines GmbH (TAE) model TAE 125-02-99 reciprocating engines with clutch, part number (P/N) 05-7211-K000304, installed. These engines are installed on, but not limited to, Cessna 172 and (Reims-built) F172 series (STC No. SA01303WI); and Diamond DA42 airplanes.
We are adopting a new airworthiness directive (AD) for the product listed above. 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. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) For engines that have accumulated, on the effective date of this AD, less than 50 flight hours (FH) since installing clutch, P/N 05-7211-K000304: Upon the accumulation of 50 FH since installing clutch, P/N 05-7211-K000304, replace the clutch as specified in TAE SB TM TAE 125-1006 P1, Revision 1, dated May 30, 2008.
(2) For engines that have accumulated, on the effective date of this AD, 50 or more FH since installing clutch, P/N 05-7211-K000304: Before further flight, replace the clutch as specified in TAE SB TM TAE 125-1006 P1, Revision 1, dated May 30, 2008.
We have further clarified the corrective action by specifying the P/N of each affected clutch, and timing the compliance period from when the clutch was installed instead of when it was last inspected.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
