Door Opening in flight?

[Red Air Rambo]

Just received this e-mail from a friend........

Hi , well my friend went and looked at the skymaster yesterday at ........, on the demo flight with a so called experienced pilot / mechanic climbing through 10K the boor blew open, he said the upper door took a chunk of the leading edge of the wing out and the lower door damaged the strut along with the door window blowing out, not a good day.


Not sure what caused it but must have to be over pressure and not checking the max pressure gauge. I would imagine the aircraft is junk after that. They confirmed the door was locked and pins engaged.



He's done with P Skymasters. Lucky to be alive, His wife was terrified.



Cheers


Has anyone heard of this happening? My thoughts are that it was not latched properly, possibly not getting the lower door closed correctly due to chain interference?
