As I remember, all crashes happen when I was pilot in a new DLC Helicopter with advanced flight mode enabled.
No custom mods enabled, PS3 controller with XBOX360 emulation connected.
Game was very stable in same configuration before Helicopters DLC (last issue I had was the PhysX3_x86.dll bug one year ago)
