Sorry about the grammar and spelling in the previous post, I was in a hurry for I had to go for a mission.
I mean that Restricted doesn't have anything to do with accidents. The thing is that those aircrafts are much cheaper than non restricted, so if a company buys that type of a/c in some way means that they are trying to spend as little money as they can in mantaining them so they might end up bying bogus parts and munting componets that are quite doubtfull in logs( I do Know that not all operators follow the same rules but we all know that what i'm saying is quite true in many cases).
