Now the problem is how many of these parts are going to show up on the black market for aircraft parts, a reportedly multi million dollar market, that deals in parts taken off broken or even crashed aircraft, or in this case jobbers that do not want to get caught holding these parts that can not be sold on the open market. These black market parts usually show up in third world aircraft maintenance shops, but have made it into the USA markets at times. The cost of a black market part over a FAA supported market cost is in the 1/3 to 1/10 value. So it is always a problem when costs for repairs are getting high. Many airlines will not leave repair parts on their planes once they get to America, they just do the repairs over again to make sure of the parts and the installation.
