My god I think I know the answer. I'm pretty inexperienced at this but I did trip across your problem last week. Apparently FS2002 has an 'aircraft converter' which will convert aircraft from previous editions into 2002. I saw it in the root directory (that means just inside the normal FS2002 director). I didn't have to use it in the end so Ican't recommend it or not as the case may be. Good luck....
