PA39
It might depend on what happened with the prop. Or perhaps like happened to the young fella who died in the Whyalla prang, he had an engine let go that clam shelled the cowls and the plane was unflyable with the thrust from the other. Had to close the throttle and glide it in to a sheep paddock.
I hope CASA, Chief pilot or whoever do not repeat the BS on this poor chap if that ws the case here.
