Thielert Piston Engines

AD/THIELERT/7 Amdt 1 High Pressure Fuel Line Bracket 5/2008 TX

Applicability:

Thielert Aircraft Engines TAE125-02-99 (CENTURION 2.0) engines, Serial Number (S/N) from 02-02-1500, up to and including S/N 02-02-2279.

Note 1:  These engines are known to be installed on, but not limited to, Cessna 172 and (Reims-built) F172 series, Piper PA-28 series, APEX (Robin) DR 400 series, and Diamond DA40 and DA42 series aircraft.

Requirement:

Unless previously accomplished, install a supporting high pressure fuel line bracket in accordance with Thielert Aircraft Engines Service Bulletin TM TAE 125-1005 P1, Revision 2 dated 6 March 2008 or later NAA approved revision.

Note 2:  EASA AD 2008-0056-E dated 07 March 2008 refers.

Compliance:

Before Further flight, after the effective date of this AD.

This Amendment becomes effective on 13 March 2008.

Background:

In-flight engine shutdown incidents were reported on aircraft equipped with a TAE125-02-99 engine.  This was found to be mainly the result of a cracked high pressure fuel line between the high-pressure pump and the fuel rail.  These cracks were caused by vibration.  This AD requires the installation of a supporting bracket on all affected TAE125-02-99 engines.

The current Amendment reduces compliance time to ‘before further flight’.

The original issue of this AD became effective on 3 March 2008.
