The plagiarism, falsification of products has been and will always be one of the great problems of mankind and seemingly unresolved, despite the legal mechanisms, technological, technical for protection.
Piracy is not limited to clothing, shoes, dvds, perfumes as we think naively.
Fake products have been found in commercial transatlantic aircraft, despite a strict control of suppliers and even in the Army Helicopters.
How a fake part affects me?
Just imagine you are in transatlantic flight with fake parts.
If the original part lasted 20,000 hours of flight, the fake part play perfect in appearance, material, weight, stamps, certificates, holograms, and it would last only 2,000 hours.
Your transatlantic flight to Europe have a high probability of failure, unexpected crash.
Even with all the maintenance checks, and since no one imagined a fake part at the plane and that was expected more 18,000 hours of normal operation. Your flight could be in the range of the last hours of the 2,000 hours!
A Flight with 600 passengers, 400 tons crash due to an electro-hydraulic-mechanical-electronic failure just because of a little chinese fake part. It can happen.
