Let’s start with the definition of a cloned part. SAE Aerospace Standard AS6171 Test Methods Standard; General Requirements, Suspect/Counterfeit, Electrical, Electronic, and Electromechanical Parts defines cloned parts as one of seven counterfeit part types:
A reproduction of a part produced by an unauthorized manufacturer without approval or design authority that replicates the authorized manufacturer’s part. NOTE: Cloning eliminates the large development cost of a part. Cloning can be done in two ways: by reverse engineering or by obtaining design information and/or technical data inappropriately (such as by unauthorized knowledge transfer from a person with access to the part design).
