accident was a 737, that was many years ago and several generations of aircraft ago. that was a structural failure of the fuselage itself. this fuselage is a composite structure and i don t see i evidence of the fuselage itself being structurally damaged. this is a failure of either the installation or the mechanical build of that door itself. so that s where i would start looking right away, is those fastening points. you can see in the photos if you look very closely, there s four little attachment points. those attachment points that stick out are where the door is fastened to the fuselage. and you can see that those are intact. so the first place i would like is how is it secured, was it actually secured properly. the other thing i would look at is, was there some maintenance where the seats were just installed, was the configuration recently changed, because when they change the configuration of the seating, that door comes out for maintenance access so they can get that done, and
one would have maintained it since installation to the time of this incident yesterday in the ten weeks that it has been flying some 150 flights? you re zeroing in on installation, not mapnipulation of it after installation to now? that s a great question. it really does depend. the fact that the certificate was issued in october tells us that the aircraft was air worthy after the time. each one of the air carriers that take delivery of these aircraft, they modify them for their own purpose. they may put their own seats in. they may change the pitch, which would mean more or less seats in the aircraft. if they did that, they would do it through this extra door as a maintenance access. it s very possible that was taken off to remove and put in
