Hi Bob;

Don't know about the Aztec as I've never had one come open on me, but I've
had the door open on me in a 140 Cherokee and closed it in flight with no
"panic" issues. Also once in a Cessna 336.
There is a pressure problem, but if you just grab the door without pushing
it and yank it closed with a single direction pull it should close ok.
Opening the canopy vents did help if I remember.

If the door of an Aztec pops open, it will only open about 4-6 inches and
will kind of oscillate back and forth between those extremes. Causes some
tail feather buffeting. Anyone trying to pull the door shut is fighting
air pressure and wasting his or her time.
