Thielert Aircraft Engines GmbH (TAE) Model TAE 125-01 Reciprocating Engines
This AD applies to Thielert Aircraft Engines GmbH (TAE) model TAE 125-01 reciprocating engines, excluding engines that have been modified to TAE Design Modification No. 2007-001. These engines are installed in, but not limited to, Diamond Aircraft Industries Model DA42, Piper PA-28-61 (Supplemental Type Certificate (STC) No. SA03303AT), Cessna 172F, 172G, 172H, 172I, 172K, 172L, 172M, 172N, 172P, 172R, 172S, F172F, F172G, F172H, F172K, F172L, F172M, F172N, and F172P (STC No. SA01303WI) airplanes.
We are adopting a new airworthiness directive (AD) for the products 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) Within the next 110 flight hours, or during the next scheduled maintenance, whichever occurs first after the effective date of this AD, inspect the engine and engine oil for any evidence or pieces of broken piston cooling nozzles.
(2) Use the inspection instructions in Thielert Service Bulletin No. TM TAE 125-0017, Revision 2, dated February 22, 2008, to perform the inspection.
(3) Thereafter, repetitively inspect the engine and engine oil for any evidence or pieces of broken piston cooling nozzles, within every additional 100 flight hours.
(4) If any evidence of a failed cooling nozzle is found, replace the failed cooling nozzle before further flight.
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.
