An unapproved part is a part that has not been produced IAW Part 21, maintained IAW Parts 43 and 91, and meets applicable design standards.
If you run into an unapproved part, don't use it. Every part made has to have the required paperwork documenting that has been made or repaired to acceptable standards. Of course they're dangerous, I don't have to go into that.

Bogus parts often come with full documentation, including FAA form 8130. Sometimes the physical appearance of the part will give away it's true origin. Lack of manufacturer's markings or unusual weight, texture or color (due to differences in materials and manufacturing processes) are often the only clue to the part's illegality. Besides the mechanic, the receiving inspector and parts room personnel must also share the responsibility for identifying any suspected unapproved parts.

Thanks for responding, to the topic and I agree, Bogus Parts can be even approved with all the paperwork done and are sometimes very difficult to identify even by the highly qualified mechanics. Major airlines sometimes know they have some in their aircrafts 'cause they cost a lot less... (Any more to come?, Hope so!)
