...It hasn't been determined yet, but all indications point toward the retaining bolting, nuts and loctite not being properly installed...

One of the news reports I heard this evening, while driving home from work, said that the NTSB hasn't yet found any evidence that the necessary bolts were ever installed at all. The very thought of that is astonishing...

I wonder...(and somebody here probably knows): Are there records of who actually installed that door plug and who inspected that person's work? Are there video records of the construction?
 
I don't think this is over.......

I don't think this is over by a long shot. When they investigate that factory that has been building fuselages for Boeing, I'll bet it will be like opening a can of worms. Not only the installers, but the inspectors and the whole shebang.

What I don't understand is why no one was sitting next to it. Those are my favorite seats because of the extra leg room. I haven't flown for a decade but outside of first class those seats provide the most legroom and were my first choice. They always came with the understanding that in an emergency you would be required to help folks off the plane, etc.

That was not an emergency exit. The seats were spaced like all the others. No exit door installed.

In 20 years of working on AF aircraft, I never used "Locktite" once. Everything was secured with locknuts, castle nuts & cotter pin, or safetywire.

IMNSHO, Boeing has been in a quality control hole since McDonnell took them over with Boeing's money. Within a short space of time, nearly all the senior types were ex-McD. A Boeing engineer said that one of these guys stood up in front of a bunch of engineers and said that nothing they did there was special. Excuse me? Keeping up to 300 or more people up in the sky by a means still not fully understood isn't special? Well, it looks like that exec's words have come true: Boeing aren't doing anything special.:(
 
Rattling?

Juan Brown's first report showed the castellated nuts on the hinge bolts also fixed with threadlocker (locktite). My supposition is that they were using threadlocker to stop any nut or bolt movement when the plug rattled around in its tracks. Brown's third installment shows how the automated pressurization system bumps cabin pressure by 0.1 psi on first throttle movement. This is done to push all the emergency exit doors, and this plug, against the hull and stop rattling in their cam tracks. The hinge bolt is an odd connection. It holds the door down against a spring. The spring assists lifting the door up on removal. I'm speculating that they don't want to bolt the plug to the stop pads for some reason.
 
Yes, a miracle. In 6 months or so, Mentour Pilot will have detailed video on this with all the info.
 
That section of fuselage with the "plug" installed is built by a sub in Wichita. The sub is partially owned by Boeing and is in fact an old Boeing plant. I assume Boeing has their own inspectors there. All of the manufacturing steps and inspections are usually spelling out on step-by-step detailed instructions with sign offs as to who performed each operation and, where required, inspected each operation.
 
I don't think...

IMO this has all the appearances of very poor maintenance and inspections by the airline.

I don't think that the door installation, being a 'plug' door was something that the airline could or would inspect, but their cavalier attitude toward how to deal with safety warnings doesn't give me a lot of confidence.

I was thinking that Mayday Air Disasters would be on it soon, too. Most of their episodes are about the ones with tragic outcomes, but occasionally they will do one that landed safely. They have to hire actors, reenact the incident, and interview surviving passengers, though; so it may take quite a bit longer.

Loose bolts...? Are you kiddin' me? Given how planes vibrate, somebody shoulda used Loctite red... Or just welded the dang door plug in place.

This could actually be a design flaw. Plane skin flex working on the plug and fasteners.

Sears Tower had to replace mucho curtain wall glass because of building flexing beyond the glazed openings ability to hold the pane on windy days. Building was designed to move 36" at the top and whole sheets of glazing would get sucked right out.

I guess one of the things we now have to carry in our carry-on luggage is a roll of duct tape and really heavy sheet plastic to cover gaping holes in our chosen aircraft.

They would periodically, but not so soon after delivery.
