Yes, if Chief deletes the [fltsim.x] section in the NBAI F-14 aircraft.cfg file that links to the Russian texture folder and renumbers the following [fltsim.x] sections appropriately, the NBAI F-14 with the Russian texture will no longer appear in his FSX, but the other NBAI F-14's and any other AI aircraft included in that FSX Traffic file should still appear in his FSX as long as they remain installed.
Easier way to do that is just to rename the title of that AI plane with Russian textures. Then one don't have to change all the n+1 after it remaining [fltsim.xx] numbers. That might take some time (I have some AI planes with nearly 100 liveries

). If there are two planes (any planes - flyable or AI) with the same title, FSX returns an error. If there is a title of AI plane that isn't in any traffic file, FSX wont bother to do anything but don't show that AI-plane.
Cheaf, because you now know the folder (directory) of F-14A it wouldn't be a big thing to do the change (I wrote above) in it's aircraft.cfg file. So just the "Russian plane" would disappear.
To speak of AI (these hints are not necessary in this case) if one has much AI traffic it's useful to make a separete folder under Simobjects folder for AI traffic. I have one for MAIW and another for other AI. These folders must to be declared in FSX.cfg file in order to AI traffic work. Under is part of my FSX.cfg:
[Main]
User Objects=Airplane, Helicopter
SimObjectPaths.0=SimObjects\Airplanes
SimObjectPaths.1=SimObjects\Rotorcraft
SimObjectPaths.2=SimObjects\GroundVehicles
SimObjectPaths.3=SimObjects\Boats
SimObjectPaths.4=SimObjects\Animals
SimObjectPaths.5=SimObjects\Misc
SimObjectPaths.6=SimObjects\AI-planes
SimObjectPaths.7=SimObjects\MAIW
...
Make also a space between different partitions (like [Main]) of the FSX.cfg file. It helps reading the file. Wonder why MS didn't do that in the first place as default.
