'Laid off pilot now selling aircraft parts' - thats nothing. I know an aircraft parts salesman who has just moved into solar panel sales. That is after ### years in the industry. (wonder why he did that? too many bogus parts and couldn't sleep at night maybe?)
Actually, yohan722, for a moment of seriousness, if you really don't appreciate the scale of the 'bogus part' problem, you will have your own reasons. It would not be proper for me to comment why without knowing you. What you can do is have a look at the FAA website, the UK CAA website etc and find the publicly accessable documented matter that deals with Suspect Unapproved Parts. It really is a multi-million dollar industry in the good ole US of A.
I am hopeful that with you having been at the 'driving end' of the business, you will have far higher scruples than some, and that you will research your company's practices very closely. I am sure that they are bone fida in all respects. But, check anyway for your own piece of mind. You never know what you may unearth.
