Airworthiness Directive · Amendment 39-18464 · Technify Motors GmbH Reciprocating Engines
Technify Motors GmbH Reciprocating Engines
This AD applies to all Technify Motors GmbH TAE 125-02-99 and TAE 125-02-114 reciprocating engines with a fuel feed pump, part number (P/N) 05-7312-K0073xx, or P/N 05-7312-K0133xx, where “xx” can be any number, installed.
We are adopting a new airworthiness directive (AD) for certain Technify Motors GmbH (type certificate previously held by Thielert Aircraft Engines GmbH) TAE 125-02-99 and TAE 125-02-114 reciprocating engines. This AD requires removal of affected fuel feed pumps. This AD was prompted by reports of in-flight shutdowns on TAE 125-02 engines. We are issuing this AD to prevent failure of the fuel feed pump, damage to the engine, and damage to the airplane.
After the effective date of this AD, do not install onto any engine, any fuel feed pump, P/N 05-7312-K0073xx or P/N 05-7312-K0133xx, where “xx” can be any number, if the fuel feed pump has 600 hours or more TIS. If TIS of a fuel feed pump is unknown or has exceeded 600 hours TIS, then the fuel feed pump is not eligible for installation. Rebuilt, overhauled, or repaired fuel feed pumps or fuel feed pumps that lack a serial number, are not eligible for installation.
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.
