I create all my airport on a 64bit operating system for a 32bit program, you can't encode in 64bit, FSX wouldn't run it, and P3D would spit the dummy, my airport also work in X-Plane once converted, except the photo-real.
If you get CTD I would check your FSX.cfg file and make sure you haven't made an error in it, if everything else works and my airport causes the crash it's not always that simple, it could be anything like a GUID being repeated, maybe I have one created that got used in another scenery by someone else, highly unlikely but very possible, I also check these between my airports to make sure I don't repeat them, it could be anything, but I would suspect a texture issue going between one airport and mine, have you checked every texture to make sure it's a multiple of 4, if one is wrong FSX will spit the dummy and so will P3D, load my airport and go in the other direction, it should crash the same, check also you're not mixing FS9 scenery and FSX together, that's common mistake and causes of many Crashes to desktop
