I guess that is exactly the problem, quality control! My earlier mention about paint related to adhesion and to striping. I was aware of a Citation V that arrived in SA brand new some years ago and the paint stared falling off. Cessna agreed to a complete respray which was to have been carried out locally. I cannot remember the figure but it was in excess of 100kg of body putty was removed when the paint was stripped!!! This on a brand new aircraft. I would rather carry that in the form of an extra passenger and bags!! Raytheon did have similar problems with quality control. Not sure if they are resolved.
