This photo (a -900ER version) seems to show that the door plug interior and door plug fuselage frame area are painted white before leaving Spirit. The 1R door is obvious, the door plug appears to be if you zoom in. I wouldn't think they would change this painting process on the MAX https://i.imgur....
Jump to postI think we can eliminate the idea that it was Spirit that was both responsible for the final closure of the plug door and thus ensuring locking bolts were in place for the final closure before delivery. It does though appear that Spirit was despatching fuselages with loose bolts, another distinctly...
Jump to postThat is not the door plug system that is being discussed in this thread. Yes, thus the reason I said: Here is a picture of a different type of door I saw that you said that, BUT you were responding to someone that asked: This recent Seattle Times article has an excellent illustration of the plug an...
Jump to postThe door plug is not removed and reinstalled at Renton according to Dominic Gates, longtime aerospace reporter for the Seattle Times. See the comment section of the linked article. Not sure if "removed and reinstalled" is considered the same as "open and closed" in this case.
Jump to postOn the frame side, there is probably a wear plate of some kind, that is replaceable. You don't want the fitting itself to wear, because it would typically be more difficult to replace the entire fitting. Here is a picture of a different type of door, you can see the fittings have small copper color...

Jump to postVery good description and drawing of the locking mechanism. Thank you for sharing. Question: How strong are the two springs at the lower hinges? Are they strong enough to push the plug upwards and out of the guide tracks or is additional force from the operator required and the springs are just hel...
Jump to postThe plug open as might be expected. It was said upthread that they are opened on the Boeing assembly line. Interestingly, you can comb thru hundreds of photos online of the Renton assembly line and find no images of the door plug open. Which, isn't to say they don't open it, but you'd think there w...

Jump to postI understand there’s lots of confusion and people saying different things. A lot of it seems to just be semantics. But it is definitely not the case that the plug is bigger than the opening like doors are. At the risk of adding confusion, this isn't really true. The door plug is larger than the ope...
Jump to postOk then you’re right. It’s impossible for a plug to escape from an aircraft mid flight. Not sure what this thread is about. You are correct it is not a door, but it does push against pads on the airframe due to pressure differential. Not a true plug, but also not just held on by bolts. The 12 pads ...

As has been mentioned ad nauseum in this thread, the plug is not like a door that pushes against the airframe from pressure differential. It is simply attached via hardware.

The door made it about a quarter mile further away laterally from the flights ground track than the cell phone was.
Yikes. Seems like a Boeing/Spirit issue then. I’m not sure how they can be trusted. They’re going to need more than a short safety webcast to get that company in order. Safety wire AD in 3, 2….

Looking at this video on how the plug mounts and locks in place: https://www.youtube.com/watch?v=maLBGFYl9_o I think we will find out that the lift assist springs were out of adjustment. I would guess they are not designed to be providing a constant upward force on the door, which would put a consta...

Also, the article linked in the tweet implies they moved passengers in that row, which honestly doesn't seem like the best idea. And if they did, why would they move 26B and leave 26C passenger.

Jump to postVery stupid question, but curious minds want to know: Other than weight (the slide pack, etc) and the additional fittings to make it an exit rather than plugged, are there any other reasons why an airline wouldn't just opt to leave it as an exit door the way it was designed versus plugging it, rega...

So do we have any ideas where he put it down yet? Actually landed it….crashed it into a field…or into a Walmart or whatever it was he was claiming?
