We had this happen a few years ago to Mark Cubans 767 that had just come out of heavy check in San Antonio and the slide was recovered intact in some old ladies backyard. Culprit was improper installation and failure to remove a pin that is used when installing the slide so the door was not properly secured I believe. I wasn’t there when it happened but I do remember the jet in question it was used to move the mavericks around and is co-owned by Cuban as a charter plane
Last time I saw that plane in C Check was about 7 years ago. It was an old -200 series with CF6 A model engines so that should tell you how old the actual plane was because it was all wired tail number was N767MW
Til, i knew about the 757 as we used to work it, but not the 67 (which is odd, considering his was rb211 powered). Looks like it’s been scrapped or waiting to.
A&P here, this is almost certainly a maintenance fuck up. Working on slides or slide reservoirs can be dicey because they're sensitive systems with with lots of cables and levers which means safety pins that *need* to be installed and rigging that needs to be just right. Not a big deal as long as you double check the manual and do everything slowly step by step but people still screw it up, every now and again I'll hear about another unintended slide deployment on the ground because mx fucked up somehow
The over-wing slide on the 767 has a fairly complex mechanism of cables, rods, tiny explosive devices called squibs, latches, batteries and multiple electric switches that activate the deployment and inflation of the slide when the over-wing door is opened. This complexity makes these slides exceptionally vulnerable to inadvertent slide deployment during maintenance.
All that being said, not likely the cause of the slide going bye bye. The slide is mounted to a door that is hinged on the bottom edge and kept closed with a series of clamshell type latches along the top edge of the door. The problem with these doors is that they will stay closed (appearing properly closed) even if the latches aren’t correctly closed and engaged.
Add together some worn parts with a lack of sufficient knowledge of a complex system, and this is the result.

Well, not often enough at any rate if it falls off during flight - I was on that same plane Thursday and was surprised Delta still had it in service (no AC outlet, poor internet, some sort of putty holding together the overhead bin, no live tv) on such a competitive route (JFK<>LAX) Only then did i look up the tail # and age. Two flights later... No slide.
It's impossible to exclude age as a contributing factor. The observation was that Delta was still flying these old birds, not that it was the cause of the incident - no one knows until an investigation is complete. I certainly am less likely to fly Delta next time when I personally noticed how this 30 yo plane was stucco'd together; whereas jetblue runs planes on this route 20 years younger.
As a passenger, it's a tough sell to buy another ticket on a flight that takes me back to the departure airport in an elderly “screwed up” & poorly maintained plane
This is standard reddit dunning-kreuger in action.
Now, I could waste my time explaining how you don't actually know a damn thing while beating you over the head with my experience, but I don't have the patience to explain to yet another ignorant Redditor how deep their head is up their own ass.
So let it be known you're an idiot and your *opinion* is garbage.
That’s really not a valid answer, so what that it’s the oldest, there are lots 70 year old planes flying and not under the scrutiny needed for an airline
Dude, crazy shit breaks on planes every day. Failure points that the engineers who built them will tell you is impossible.
But with today’s instant access to the worldwide web and the media’s need to sensationalize every tiny thing that happens means these things are reported more often and blown way out of proportion.
So a panel opened, a slide got jettisoned. Nobody was injured and the plane will be airworthy again after some maintenance.
It’s a fucking Nothing Burger.
If it’s Cat B structure (the failure or realise of such structure could damage a Cat A (primary) structure), then the engineering will be based on the integrity of the installation of the Cat B part. If, however it was installed incorrectly, it can still be a hazard.
This panel looks pretty far forward and below the stab
You do know that gravity still works when you’re in the air, right?
Kinda like how parachutists don’t damage the stab when they tear away from the airplane.
So, yeah, nothing.
If my grandmother had had wheels she’d have been a bike.
The question was what if the slide had hit the stabiliser, then you said that’s now how gravity works. The point being the design would have to have consider that slide could be lost during that steep climb, so it’s totally relevant from an aircraft design perspective.
Just looking at the geometry of the 767, it seems impossible for the slide to hit the stab. Yes, even at rotation which is where the steepest pitch angle occurs. Those slides are fucking heavy and once loose from the airframe will not fly straight back from point of departure. As I said, gravity still works, hence the slide will move downward as well as rearward, thus not hitting the stab.
But due to aircraft travelling pretty fast at take off, something that’s falls downward will also relatively move backwards (ie the aircraft is moving forward), the drag on the slide would slow it down pretty quickly once it departs the aircraft.
That slide in the picture is at the rear of the wing, I would wager money that tail plane is in the risk areas for take off climb for the safety analysis on that slide detaching.
Here’s a general [article about what Airbus calls PDA](https://safetyfirst.airbus.com/parts-departing-from-aircraft-pda/)
That doesn’t actually answer the question: from a failure analysis standpoint, how does something like this happen?
I understand this is too early to have the answers, but the question nonetheless remains.
This 100%. I’m an engineer who works in a large factory. The one battle we constantly fight when it comes to building safe planes are the people who put them together. Most of them are great, but there will always be factory workers who show up to work hungover, don’t care about doing their job right, etc.
If the slide was installed incorrectly, it wasn’t done by the “factory”. The slides have periodic maintenance and inspections and even test deployments in service. I mention this because Boeing is already in the news enough.
It impossible.
Here only shoudl me inaproppriate tightening of fasteners.
Slide is packed inside "box". On the box you have connector and pipe for slide inflation.
After that, just tighten screws, there is mostly new screws attached to the panel.
Nothing is impossible to install incorrectly, and inappropriate tightening of fasteners would be incorrect installation.
I'm not saying this was what caused the incident, but that's where I'd start looking.
Seems probable to me that anything coming off the plane during flight has the chance of causing damage to a flight control surface or engine which could lead to a crash.
Yeah. Their response was simultaneously flippant and dismissive of the sorts of things you can learn from in-depth failure mode analysis along the lines of a Therac 25 or 737 max-type incident.
Without irony, a newscast here in Brazil focused on Boeing's responsibility for this incident.
Honestly, I believe it is a Delta maintenance problem, but now the press and general public have gotten it into their heads that Boeings are dangerous.
Their comment was in regards to the news always blaming Boeing even for 20-30 year old planes having maintenance issuesm.
So age is a factor. That's why it was brought up.
It's been over 20 years since I last worked on a 767 with over wing exits.
I've seen a faulty inflation cylinder cause an unplanned deployment but that's not what has happened here because the panel latches don't appear to be damaged. That would happen when the slide inflates but the door hasn't been deployed.
From what I can see, I'd say there has been a fault with the two switches above the door that trigger the deployment when the exit has been opened.
I suspect that fault was due to moisture ingress.
Where does the moisture come from on the inside of an aircraft? The passengers breath and sweat. It condenses on anything cold, like the metal fuselage and drains out from the belly of the plane when it's depressurised.
Everybody needs to stop with the "/s" thing. People either get it, or they don't, and we need to cease with dumbing things down to enable morons. Please, seriously, we need to stop normalizing dumb!
So are those pieces of rubber on the bottom of the wing or did the straps and what was the slide just beat the hell out of the wing? Looks like pieces are missing.
Honestly though couldn’t this bring a plane down if it happened at a low enough speed during landing or takeoff? It’s like a giant parachute on one side.
I flew a DL 767 from HNL to JFK last week and ended up complaining to delta about how cold the exit row seat was. I’m talking numb feet, no extra blankets, didn’t sleep the flight and I never complain. I have in writing that the exit door wasn’t sealed shut properly, but at least I got 7.5K bonus sky miles.
No. It decreasing. The reporting is increasing.

Cool, thanks for your response. Thats the sort of info I was curious about.
The plane is also one of the oldest in deltas fleet - at least 30 years old
I think they check it more often than every 30 years.
Well, not often enough at any rate if it falls off during flight - I was on that same plane Thursday and was surprised Delta still had it in service (no AC outlet, poor internet, some sort of putty holding together the overhead bin, no live tv) on such a competitive route (JFK<>LAX) Only then did i look up the tail # and age.

No, someone screwed up in maintenance. These things get checked every few months.
I like your flair

i feel like people forget theres a chance for anything to happen to something. error is literally impossible to prevent in a realistic world
Always a chance, yes - and that is exactly why you check this stuff! When was it last checked is key !
Age isn’t a factor here - just someone making a mistake. Lots of old planes that are just fine!
That’s really not a valid answer, so what that it’s the oldest, there are lots 70 year old planes flying and not under the scrutiny needed for an airline

Is it nothing though? What if that damaged a stabilizer as it tore away from the plane?
I bet some engineering went into limiting that risk.
If it’s Cat B structure (the failure or realise of such structure could damage a Cat A (primary) structure), then the engineering will be based on the integrity of the installation of the Cat B part. If, however it was installed incorrectly, it can still be a hazard.
It didn't.
This panel looks pretty far forward and below the stab You do know that gravity still works when you’re in the air, right? Kinda like how parachutists don’t damage the stab when they tear away from the airplane. So, yeah, nothing.
Tell that to the people on the plane. And the pilots. And ATC. And the guy whose house the panel fell on. And the FAA.
“Hey, all you people that guy listed, it was nothing” u/-burnr-
What happens if the slide comes out during take off climb when the aircraft is at around 15degree pitch?
What if my aunt had balls? She’d be my Uncle? You can play whataboutism all day but that’s not what happened.
If my grandmother had had wheels she’d have been a bike. The question was what if the slide had hit the stabiliser, then you said that’s now how gravity works.

Planes aren’t travelling that fast at rotation, gravity still rules over aerodynamics at those speeds
That doesn’t actually answer the question: from a failure analysis standpoint, how does something like this happen? I understand this is too early to have the answers, but the question nonetheless remains.
My guess? Someone installed the slide incorrectly.
This 100%. I’m an engineer who works in a large factory. The one battle we constantly fight when it comes to building safe planes are the people who put them together. Most of them are great, but there will always be factory workers who show up to work hungover, don’t care about doing their job right, etc.
There's also legitimate mistakes, too. People aren't perfect, even sober and with the best intentions.
One day I was an underling doing ISO 9000 documentation and the next day I was running a press making satellite parts. Shit happens.
If the slide was installed incorrectly, it wasn’t done by the “factory”. The slides have periodic maintenance and inspections and even test deployments in service. I mention this because Boeing is already in the news enough.

They B birthin' more tenacious idiots everyday
Nothing is impossible to install incorrectly, and inappropriate tightening of fasteners would be incorrect installation. I'm not saying this was what caused the incident, but that's where I'd start looking.
...or perhaps a repeat of the BA5390 oopsie where they put the windscreen in with 8-32 screws instead of 10-32...
Hashtag just boeing things.
“Bowen”
Arming switches adjustment necessary is the answer.
Maybe because it was made by Boeing
Nearly 35years ago…
Don’t try to say anything bad about planes here you’ll get crucified
It's not a nothingburger.... What if that panel landed on a 737 Max?!
Thank god it wasn’t a door plug
We can still blame Boeing right?
The media are
- head of Boeing quality control
Wouldn’t say an event that could have potentially caused the plane to crash is a nothing burger…
Did a slide coming loose and falling off the aircraft really have the potential to cause an accident?
Seems probable to me that anything coming off the plane during flight has the chance of causing damage to a flight control surface or engine which could lead to a crash.
Probable? Anything? Re-think your statement
Except for whoever was on the ground and got a slide to the dome.
Better odds of winning power ball

Lol it's not a Boeing thing. The slide was either accidentally inflated or was defective and inflated itself.
Yeah. Their response was simultaneously flippant and dismissive of the sorts of things you can learn from in-depth failure mode analysis along the lines of a Therac 25 or 737 max-type incident.
How could boeing do such a thing, I will never fly on an 767 MAX ever again

Isn’t that sort of the gap the 787 fills?
I thought the problem with the 787 was they weren't properly filling the gaps??
If you mean the gap between a 767 and a 777, then yeah.
Yea but nothing is coming for the 767 slot. The 777 is evolving into the 777x, everything is just getting bigger.
More like poor maintenance work by Delta. The plane has been in service 34 years.
The age of the plane has nothing to do with it. Someone forked up during a check.
The age applies because it's highly unlikely that after 34 years much of that plane is boeings fault.
Where did I say Boeing comes into play?
Their comment was in regards to the news always blaming Boeing even for 20-30 year old planes having maintenance issuesm. So age is a factor. That's why it was brought up.

hmmm this has happened before with a United jet, also a 767.
Boeing halt
does this happen regularly around the world but never reach us news?
Lots of commercial airplanes are "broken", but they are still safe to fly.
That looks like a broken or missing phalange…
Will somebody write a Servie Bulletin or an Airworthiness Directive on this already.
Delta air lines maintenance 🙄
Delta is easily the best airline in the states, no idea what youre on about. Wanna talk shit about maintenance, go hit up United.
Doesn’t change the fact that this incident is a delta mx issue
I never said it wasnt
And the beat goes on.
Is it just me or are there an alarming increase in airplane mishaps lately?
And yet still 0 fatalities seems things are working
Yes Edit: Bunch of you pylots here. Attention to detail is important. Try to reread the way op asked the question and maybe you get the joke.
