What I meant by once, is : did you test each plane you added before trying to install another plane, or did you installed the planes one after the other, and started the sim once it was done ?
If the latter, you made a mistake.
The problem comes most probably because you didn't install the pylons, the weapons and the guns of the planes correctly. The XDP of the planes call for these loadouts and then, as cfs3 can't find these files where they are supposed to be, it CTDs.
So...
1) Delete all the third party planes
2 ) Now, the game remembers the last plane that you used, so you have to delete this file : uisel.xml
It is in :
C:\Documents and Settings\user's name\Application Data\Microsoft\Combat Flight Simulator 3.0
It will be rebuilt and will use some stock planes.
3) Then reinstall the faulty plane with its pylons, weapons and guns. You most likely forgot to install the Guns and Weapons pack from Avhistory : that should be mentionned in the readme if the planes are 1% ones.
BTW, there is a "how to" for uninstalling and reinstalling cfs3 :

There's also a good tut on installing planes there :

install something, then starts the sim and check (for a plane) that everything works fine (test the different loadouts, etc...). If it's OK, then install another one, test again, etc...
If you do so, it will be very easy for you to backtrack and pinpoint the culprit that causes cfs3 to crash.
