The critical issue would be Vmca with a door open, it has
not been flight tested and how much Vmca will increase is
just a guess.

Piper crash to

the conclusion of
| the investigation that a passenger in the back seat was
trying to switch
| places with someone in the front and the door
inadvertently popped open.
| At that point the investigator determined, from his own
similar
| experience, that the plane sunk like a rock due to
critical disruption of
| the airflow to that could not be corrected in flight.
| --The door could not be closed again!---
|
| As for my friend with his similar experience, his
friend's hand was all
| bloody from trying to hold it closed as much as he
could. Fortunately,
| they made a safe emergency landing at an island the just
happened to be
| nearby.
|
| I've only flow small single engines and had NO IDEA how
serious this
| could be. They don't teach you that in flight school.
Or is it because
| single engines with only one door do not react the same
as the twins.
|
| Tell me the straight skinny so I know next time I go
flying.
