Anyone notice this comment underneath Dominic Gates article in the Seattle Times, ref post 688:
"But there is a line tech, somewhere, that is likely removing these doors after manufacture AND after installation. Look at the picture from the United Airlines loose bolts. Everyone is focusing on the castle nut bolts, but the loose bolts in the picture are the bolts that connect the bottom hinge guide to the frame of the plug/door. Those should never be unscrewed, ever, BUT there are obvious tool marks on the heads of those bolts (post manufacture). Why would the hinges guide parts be removed from the door? ... It's obvious. The normal opening of the plug only goes 15 degrees. Someone wanted a quick way to remove the plug completely, for working in the cabin (maybe not dragging equipment around). Nobody wants to deal with spring tensioners or anything complicated, which would be needed if the plug was properly removed from the fuselage. So the shortcut is to remove the bottom hinge parts from the plug/door and pull the door out from the bottom. That's what the United Airlines picture shows, and it's likely what the other newly found loose bolts are (Alaska/UA hulls)."
Seems feasible?
