Nooluv,
Going back to your original point and considering only engines. I believe the regulators only ever account for a single failure when developing rules. After all what set of rules are you going to develop for a twin engine a/c if you consider multiple failures?
If something happens on the day that is outside the scope of the rules then that is when the crew start to really earn their money.
