Having owned an Aztec I am curious as to how this is an emergency? Certainly is not considered one in the POH.
Well I did wonder reading this thread.
I had this drummed into me by an instructor and am guilty of my own earlier post in that I never thought to check the POH. I have never had a door open on the Aztec fortunately and with the latching mechanism I guess it is pretty difficult.
Have you ever had the door open in flight?
