You should modify the search to fit the data in question. You should run a search for "tail separation plus both on-wing engines separation"
Once the verticle stabilizer comes off planes tend to go into flat spins, since planes weren't really designed to withstand flat spins this puts stresses on other external parts they can't handle. Engines falling off is pretty regular at that point, and sometimes the wings, all depends on how quickly the plane makes it to the ground.
