Usual answer:
In raw figures, you can choose statistics that say that flying little aeroplanes is about as dangerous as riding motorbikes (ie lots more dangerous than driving cars).
However as others have said most motorcyclists are killed by other people, whereas most pilots kill themselves.
So you can cheat. You can read the accident reports, and choose not to kill yourself in many of the favourite ways.
Thus making your odds better than those of a motorcyclist.
I fly. I gave away my motorbike years ago because driving it around amongst all those people who were out to kill me just got too frightening.
