Frankly, the whole story sounds just a little bit strange.
On my '79 P337H the door latching mechanism is very robust. Bottom half has two latching points, upper half has four. Both halves latch separately, upper half overlaps the bottom one reinforcing the latching points. It is impossible to latch the upper half if the bottom half is not closed/latched properly. One the upper part, it is impossible to rotate the handle all the way if the upper half latches did not engage properly. It is a well designed and strong system.
In order for both door halves to blow open all 6 latches or 2 separate latching mechanisms need to fail. I am having hard time imagining how this could happen. Even if the cabin pressure was over the limit and the door gave in, only the upper part should open. As soon as the door seal is breached, the pressure differential goes away. Why would the bottom half open then?
I have never heard of a P-Skymaster door opening in flight before.
It will be great if we can get more information about the incident.
What year was the P-Skymaster in question?
Any chance there were some pictures taken?
