CFM published a SOP for all sets of failures. It should be included in all airlines FCOM(same for RR). Also note that if the damage is from external(such as a AMARAM coming from a F-16), you'll less likely to survive. Most of the engine collisions with other objects results hull loss accidents(yes I know that much because I see A320s colliding in my backyard everyday
), but every incident is so seperate.
