Hi
A quick fix is to remove the visual_damage=1 from the aircraft.cfg
or you can have a look at this
http://www.freeflightdesign.com/tips/breakable.txtdont worry about the effects/dp parts as these are not used in FS9,you need the addtions for the VarPresets2002.cfg
now in fsds open each and every part and give it a new preprocess with the visablity additions,its a pain in the butt and a lot of work on a nearly completed model as every single little tiny part needs a preprocess miss 1 and you will get a spawn.Not to mention linked parts need special consideration.

PS if you have named the parts like wing,tail,Fuselage then renaming them to somthing like rwing atail mfuse ect will stop the spawns by default fs uses these names to brake a model and as there is no visablity par. in the mdl it render's the whole model
