Airworthiness Directive · Amendment 39-16415 · Thielert Aircraft Engines GmbH (TAE) Models TAE 125-01 and TAE 125-02-99 Reciprocating Engines
Thielert Aircraft Engines GmbH (TAE) Models TAE 125-01 and TAE 125-02-99 Reciprocating Engines
Superseded. A later AD replaced this one: AD 2011-23-01. Comply with the one in force.
This AD applies to Thielert Aircraft Engines GmbH (TAE):
(1) TAE 125-01 reciprocating engines (commercial designation Centurion 1.7), all serial numbers, if a clutch assembly part number (P/N) 02-7210-11001R13 is installed; and
(2) TAE 125-02-99 reciprocating engines (commercial designation Centurion 2.0), all serial numbers, if a clutch assembly P/N 05-7211-K006001 or P/N 05-7211-K006002 is installed.
(3) These engines are installed on, 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 DA40 and DA42 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) Before next flight after the effective date of this AD, identify the serial number (S/N) of each P/N 02-7210-11001R13, P/N 05-7211-K006001, and P/N 05-7211-K006002 clutch assembly installed on the airplane. If the S/N matches one of those listed in Thielert Aircraft Engines GmbH Service Bulletin (SB) No. TM TAE 125-0021, dated June 9, 2010, or SB No. TM TAE 125-1011 P1, dated June 9, 2010, as applicable to engine model, replace the clutch assembly within the following compliance times:
(i) For engines with affected clutch assemblies that have accumulated 100 flight hours or more on the effective date of this AD, replace the clutch assembly before further flight.
(ii) For engines with affected clutch assemblies that have accumulated less than 100 flight hours on the effective date of this AD, replace the clutch assembly before accumulating 100 flight hours.
(2) After the effective date of this AD:
(i) Do not install an engine having a clutch assembly that is listed by S/N in Thielert Aircraft Engines GmbH Service Bulletin (SB) No. TM TAE 125-0021, dated June 9, 2010, or SB No. TM TAE 125-1011 P1, dated June 9, 2010; and
(ii) Do not install any clutch assembly listed by S/N in Thielert Aircraft Engines GmbH Service Bulletin (SB) No. TM TAE 125-0021, dated June 9, 2010, or SB No. TM TAE 125-1011 P1, dated June 9, 2010, into any engine.
This AD differs from the Mandatory Continuing Airworthiness Information (MCAI) and/or service information as follows:
(1) EASA AD 2010-0111-E, dated June 10, 2010 (corrected June 11, 2010) has separate compliance times for engines installed on twin-engine airplanes. This AD does not.
(2) EASA AD 2010-0111-E, dated June 10, 2010 (corrected June 11, 2010) allows a single ferry flight with conditions. This AD does not.
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.
