The way I understood it, the jet engine was a time machine. When it fell through Donnie Darko's bedroom, it created a bubble in the space-time continuum, a short-lived parallel universe. Donnie died in the original universe, but lived for several weeks more in the new one. The prediction of the world coming to an end could be interpreted either as the termination of that bubble, or as his world coming to an end through the death of his girlfriend. The director's cut has a bit more about time-machines, I think. At the end, it was as if Donnie was willing the jet engine to fall through his bedroom, close the space-time bubble, kill him; thus saving his girlfriend before he ever met her.
