AD 2010-04-06 Airworthiness Directives; Thielert Aircraft Engines GmbH (TAE) Model TAE 125-01 Reciprocating Engines

Makes named: thielert. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to Thielert Aircraft Engines GmbH (TAE) model TAE 125-01 reciprocating engines, all serial numbers (S/N) up to- and- including S/N 02-01-1018. These engines are installed in, but not limited to, Diamond Aircraft Industries Model DA42, Piper PA-28-161 (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. 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. The MCAI describes the unsafe condition as: An in-flight engine shutdown incident was reported on an aircraft equipped with a TAE 125-01 engine. This was found to be mainly the result of a blockage of the scavenge oil gear pump due to a broken axial bearing of the turbocharger. The broken parts were sucked into the oil pump and caused seizure. With the pump inoperative, the separator overfilled, causing the engine oil to escape via the breather vent line. This caused a loss of oil that resulted in the engine overheating and subsequent shutdown. We are issuing this AD to prevent engine in-flight shutdown, possibly resulting in reduced control of the aircraft.

Unless already done, do the following actions within the next 50 flight hours after the effective date of this AD: (1) Modify the engine oil system by installing a filter adaptor to the catch tank. (2) Use the installation instructions in Thielert Service Bulletin No. TM TAE 125-0016, Revision 1, dated June 15, 2007, to install the filter adaptor. FAA AD Differences (f) This AD differs from the Mandatory Continuing Airworthiness Information (MCAI) as follows: (1) The MCAI compliance time states “within the next 50 flight hours after the effective date of this directive, but not later than 31 October 2007, whichever occurs first”. (2) This AD compliance time states “within the next 50 flight hours after the effective date of this AD.” Related Information (g) Refer to European Aviation Safety Agency AD 2007-0232, dated August 23, 2007, for related information.
