If someone checked th static systems for water ( by opening the drain valves by the right hand seat) and left them open, you would get decaying airspeed and altitude indications as the cabin started to pressurize after the squat switches went to 'air'.
A very good point; If memory serves me right it has an alternate pitot/static source switch on the right side of the cockpit but I don't recall if the B200 has a static drain system, if they do, would it use the "Curtis" type drain.
If that is the case they should have been modified so as not to lock open, but anything is possible.
