The chopper's death is the same no matter how or where it dies. You can't make a specific death fx trigger only when hitting buildings.
Might be codewise, but in-game when they hit a building the wreck just disappears and a few tiny pieces of debris spawn on the spot. Compared to crashing onto normal terrain, a lot less effects are triggered.
The dude here is asking whether it's possible to substitute those small pieces with something more cool.
My guess is that it's hardcoded because it looks generic regardless of what type of plane/heli crashes into buildings. Probably not possible to do anything with it, but I'm just assuming this, feel free to investigate.
