Doors popping open in flight

Unless they've changed when it comes to Bonanzas and Barons the

Society is either land and close it, or leave it alone until you get
to your destination otherwise they consider it *should* be a
non-issue.

They had lost enough pilots and passengers due to pilot distraction
trying to close a door that they have one sentence that covers it.

open at take off or on climb out. In the Deb it sounds like a shotgun
from close range. OTOH that is the cleanest the floor has ever been
in there, but it was briefly IMC in the cockpit.

Each plane is different. Adhere to what ever the manufacture, or
pilots group says.

In many planes this is normal. In a Bonanza and Baron the door is
part of the structure and when it pops open there is over an inch of
mismatch.

engines with only one door do not react the same as the twins.

Some do and some don't.


Tell me the straight skinny so I know next time I go flying.

The only way to know for sure is to read the POH and consult the
manufacturer, (and/or) pilot/owner groups.

The number one problem with doors popping open in flight is pilot
distraction. Just ask the Air Safety Foundation.

Beech Bonanza and Baron cabin doors are a very minor
problem. On the Baron the nose baggage door is another
matter. A service bulletin (and recent production
airplanes have a third safety catch which prevent the nose
door from opening more than about 1-2 inches, there is also
a net to secure baggage.
