"To die" is an intransitive verb, v.i. in the dictionary. It has no passive.
Ten people have died in an air crash in Chile.
Or you can use the verbal adjective:
Ten people are dead after an air crash in Chile.
(Note the present tense and the "after": for the crash has alreasy happened.)
If you really want to use the passive (but why?) you can say it with "kill" (transitive, v.t.):
Ten people have been killed in an air crash in Chile.
But of all these, the simple "have died" is by far the best choice.
