Boeing doors held in place by a single cable tie
The preliminary accident investigation report has come up with a picture taken after closing the plug door that afterwards departed from a Alaska 737 MAx 9 in the air. It shows it being held down by a a cable tie. THere is speculation that this would be enough to stop the door from sliding up and being able to eject for a number of flights sine there woud be litle presure on it as oon as the plane takes off and outside air pressure locks it onto its stopping pads. It could also be that the cable tie held the bag of roller stopper bolts that was to be installed by a later shift but that the last part never happened. There is a case for ripping out the floor of that particular Alaska 737 Max9 and see if anything that the investigation has so far not found have slipped down along the wall and is now laying in a hidden area that can't be checked otherwise. Another worrying picture is of a stopper bolt installed but with 2 washers. This is proably so the castelated nut can lign up with
