Airworthiness Directive · Amendment 39-16314 · Thielert Aircraft Engines GmbH (TAE) Models TAE 125-01 and TAE 125-02-99 Reciprocating Engines Installed in, but Not Limited to, Diamond Aircraft Industries Model DA 42 Airplanes
Thielert Aircraft Engines GmbH (TAE) Models TAE 125-01 and TAE 125-02-99 Reciprocating Engines Installed in, but Not Limited to, Diamond Aircraft Industries Model DA 42 Airplanes
Superseded. A later AD replaced this one: AD 2010-11-09 R1. Comply with the one in force.
This AD applies to Thielert Aircraft Engines GmbH (TAE) models TAE 125-01 and TAE 125-02-99 reciprocating engines designated with part number (P/N) 05-7200-K000301 or 02-7200-1401R1. The engines are installed on, but not limited to, Diamond Aircraft Industries Model DA 42 airplanes.
We are adopting a new airworthiness directive (AD) for the
Unless already done, do the following actions:
(1) For TAE 125-02-99 reciprocating engines with engine P/N 05-7200-K000301, within 55 flight hours after the effective date of this AD:
(i) Replace the existing PPRV with PPRV, P/N 05-7212-E002801. Use paragraphs A. through B. of Thielert Service Bulletin (SB) No. TM TAE 125-1007 P1, Revision 2, dated April 29, 2009, to do the replacement.
(ii) Install a vibration isolator, P/N 05-7212-K022302, to the gearbox assembly. Use paragraphs 1 through 20 of Thielert SB No. TM TAE 125-1009 P1, Revision 3, dated October 14, 2009, to do the installation.
(2) Thereafter, within every 300 flight hours, replace the PPRV, P/N 05-7212-E002801, with the same P/N PPRV.
(3) For TAE 125-01 reciprocating engines with engine P/N 02-7200-1401R1, within 55 flight hours after the effective date of this AD:
(i) Replace the existing PPRV with a PPRV, P/N NM-0000-0124501 or P/N 05-7212-K021401. Use paragraph 1 of Thielert SB No. TM TAE 125-0018, Revision 1, dated November 12, 2008, to do the replacement.
(ii) Inspect the electrical connectors of the PPRV and replace the connectors if damaged, and install a vibration isolator, P/N 05-7212-K023801, to the gearbox assembly. Use paragraphs 1 through 27 of Thielert SB No. TM TAE 125-0020, Revision 1, dated November 25, 2009, to do the inspection and installation.
(4) Thereafter, within every 300 flight hours, replace the PPRV with a PPRV, P/N NM-0000-0124501 or P/N 05-7212-K021401.
We have found it necessary to not reference the second paragraph of the unsafe condition from the MCAI EASA AD 2009-0224. That sentence stated that the problem has only manifested itself on those Thielert engines installed on Diamond Aircraft Industries DA 42 aircraft. The affected engines which require a PPRV could be used on other make and model airplanes in the future.
(g) We also did not reference the February 28, 2010 compliance date, which is in EASA AD 2009-0193R1, or the January 31, 2010 compliance date which is in EASA AD 2009-0224.
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.
