I know what you are talking about it did it to me for a while, real easy fix:
Before you start edited any thing on a particular plane:, right click the Aircraft Folder, go to properties, then the security tab, edit, then click on user from the list, and click to first 2 unchecked boxes, and save.
Once you do it once it, only takes like 2min the next time. It is a way to keep people from messing with important files, but in FS you mess with them a lot so it just slows you down. Do it for all the planes in the folder and you should never have to worry about that again.
