Airworthiness Directives; Technify Motors GmbH Reciprocating Engines

We propose to adopt 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 proposed AD was prompted by reports of in- flight shutdowns (IFSDs) on TAE 125-02 engines. This proposed AD would require removal of affected fuel feed pumps. We are proposing this AD to prevent failure of the fuel feed pump, which could result in damage to the engine and damage to the airplane.
