Check the model folder out and make sure there is a .mdl file in it. Then make sure that the aircraft cfg is using the same name. You might have a corrupt model file. I had a similar problem with the default B747 every time I tried to select it FS9 would stop responding I tried reloading the aircraft off of disk1 and it still would not work I finally gave up and unstalled and reinstalled fs9. Never did figure out what happened to cause this. No one in the forum had ever heard of this either. The only thing that it might have been was my OS I have windows ME and it does some strange things from time to time. For a bug free Os it is keeping RAID and BLACK FLAG in business
