I have a lot of footage and videos I have made in the past.. just uploading it all here so the wonderful people of RUclips can also enjoy it. Stay tuned.. more to come
Thanks for such a great video Stig! One thing I have been puzzling about, and still can't figure out, is how the 737NG cabin entry doors create an airtight seal. The mechanism seems extremely complex, especially with the door swinging outwards, and the bending top and bottom segments of the door. I just can't imagine how an airtight seal should be possible with a door that can fit through its frame. Like the A320, 777, and 787 families all have sliding doors that seem to seal with pressure and a gasket. It would be great if you could explain the 737NG doors in detail in a future video. My curiosity about it has been bugging me for a while now. 🤣
It’s simply a difference of design they all work the same way, all these doors are plug style, it’s the tapering of the door that allows it to move in and out of the cabin
I work for a repair station but different aircraft, I have a curiosity: how often do you need to do an operational test of the emergency exits and doors? ty
That particular test you saw happens annually. They will pick a random aircraft and designate all the doors or some doors. And they will intentionally deploy the door to make sure everything goes a up to par.
@@friedchicken1 all the slides are serialized and so are all the door assist actuators and bottles. So when they do pick the particular aircraft and the doors the numbers are all in record as it is. They are serialized and FAA PMA approved parts that are continuously tracked by a particular code. They know which aircraft it’s installed on and what door position it’s installed on. Everything is documented to the T
oh yeah , I know that, but I was wondering if a test had to be performed to each system, say, every 2 years or so. that's what I was wondering. but as you said, they pick planes at random to do functional tests :)
@@friedchicken1 yup randomly. It’s required by the FAA. The random part is because there’s thousands of aircraft in service… they want to see that if they pick any of them that the system is functioning and proper maintenance is done.
All commercial aircraft use SAE standard tooling. There are a few exceptions with interior items such as trim and cosmetic components which can be metric. But over all most of the hardware and fasteners are SAE standard (imperial). Check my tool box video and you’ll see the tools I use. 👍
Hey stig I have a doubt the one installed on B787 and B777 are they both like A320 (that only works in emergency) or they work every time open or close the door?
Oh, those are very interesting, they slide in words and up. You should see the mechanism that actually pulls that thing up, looks like a big garage door spring.
I think the door on the l1011 was the best designed. Next to impossible to accidentally blow, and no bottles to keep check of since it uses a big spring to open in an emergency.
So I have a really dumb question and will seem like I'm paranoid, but I don't ever worry about this kind of thing during flight, but is there some kind of safety long on these doors to keep a random passenger who might have a mental illness of sorts to keep from opening a door during flight? It's kind of silly but I will sometimes during the long flights to and from Tokyo as I sometimes wait for the bathroom to be unoccupied, I will open the shade from the door window to look out because I usually sit in an isle way seat during long flights so I can get up as needed. I don't have a window seat so I will look at that window sometimes to enjoy the view, but then I look at the door itself and imagine what if someone tried to open this because maybe someone is crazy. lol
If the aircraft is pressurized and flying at high altitudes, the door would be impossible to open, you would break that door handle before you open the door. So there’s no need to worry about that, and just as a precaution, always keep your seatbelt on when you’re seated.
Ok. I was wondering about that. Might have been something fictitious, but I thought I've seen something somewhere about a crazy passenger opening a door mid flight. I plan to fly so many more times in my life, I hope I don't experience any turbulence so violent that the craft makes a bad enough drop that anyone standing hits the ceiling. I have seen aftermath videos of this. In 2020 when I took my first trip to see my fiancé, just girlfriend at the time, I was on an ANA Airlines flight to Tokyo and I sat there with my seatbelt unfastened, and the flight attendant politely requested I put the belt on. My thought was why do we need these fastened although I was not going to disobey the rules although for something like 10 minutes I sat with it unfastened. lol@@StigAviation
@@TheCAG1976 the incident that you were talking about was a very unusual one, the aircraft was pretty much about to land, and was almost completely unpressurized, the disturbed passenger stood up and opened one of the doors. The flight attendant should’ve been there, because that was a flight attendant Station, I don’t know exactly how that happened, but the good news is that they landed safely. In regards to turbulence, it doesn’t really bother me because I know the aircraft can handle severe turbulence. And as for seatbelts, I always have mine fastened no matter what. Even if I’m sitting, and there’s nothing happening, I always keep my seatbelt on.
@Stig I am always surprised that the airline industry doesn’t warn passengers that wearing clothing with nylon material especially women wearing nylons will get a nasty burn if they ever had to use those slides because they are also made of nylon and nylon or nylon create quite heat friction. By the time they hit the bottom, they will definitely be running from an old retired guy. I hope this helps somebody.
Oh, trust me they do, even the FAA recommend this as well as the NTSB. But most people don’t pay attention or read. But you’re absolutely correct on wearing proper clothing when traveling.
The max was modified to its maximum extent, if they changed anything more, it would no longer be a 737. They had to keep the doors the same and upgrade different systems.
This is now one of my favorite channels
Thanks you so much. I appreciate you being here. Cheers
@@StigAviation hi I love all your videos they're so fascinating, can I ask, are you a qualified engineer with an engineering degree?
You simply can't get this content anywhere else. I love it !!!
Glad you enjoyed it David
I've been an aviation geek for so long. Thanks for your channel Stig.
My pleasure. Thank you for being here
Love your videos man, thank you for all the knowledge
My pleasure! Glad you enjoyed it
Fantastic! Enjoying these videos
Thank you Thomas. I appreciate you being here.
Your videos are very interesting and informative. Thanks
Glad you like them!
One of my favorite shorts!
Thank you
Keep on doing more vedios about aircraft maintenance sir. We are waiting
Just posted a new one. Check it out. It’s about tail strike protection 👍
I really appreciate that you mentioned the ata thanks you so much from France i wish I become an aircraft engineer soon too
You can do it! And I’m glad I can help in any way 👍
How do you keep uploading these amazing videos so frequently? Keep these B777 vids coming tho I love them ❤😊🎉
I have a lot of footage and videos I have made in the past.. just uploading it all here so the wonderful people of RUclips can also enjoy it. Stay tuned.. more to come
i’m not in the aircraft or airline industry (I do fly a lot) so no idea why i’m being fed these videos but they’re fascinating!
I’m glad you’re here. Learn why you are so safe in the aircraft you fly 👍
@@StigAviation good to know! 2m miles on the 777 plus another slug on other aircraft so good to know the hard work keeping these beasts in the air.

oh, so it is not required to do it to every serialized system but at random?

Stig could you show the solenoid lock on wing exit doors?
Thks
I’ll try to get that for you. 👍
@@StigAviation very kind. 👍
Cool, Stig - so many differences between each design! Do you need metric tools for Airbus and imperial for Boeing maintenance?
All commercial aircraft use SAE standard tooling. There are a few exceptions with interior items such as trim and cosmetic components which can be metric. But over all most of the hardware and fasteners are SAE standard (imperial). Check my tool box video and you’ll see the tools I use. 👍
Stig, not sure if you have done so, but could you do a detailed video on the emergency lighting on aircraft? Thanks!
Will do it in the future 👌
Few roll up doors anymore ne curious to see their mechanism
Rollup doors in regards to passenger entry or the windows ?
passenger entry eg. DC10 MD11 767@@StigAviation
Hey stig I have a doubt the one installed on B787 and B777 are they both like A320 (that only works in emergency) or they work every time open or close the door?
They all work as a damper to have smooth door action and in emergency
Another type of door that also fascinates me are the ones on 767 and L1011.
Oh, those are very interesting, they slide in words and up. You should see the mechanism that actually pulls that thing up, looks like a big garage door spring.

I've heard a rumor that at some airlines only mechanics are allowed to open closed doors from the outside. Could this be true?
Not true. Most times gate agents or flight attendants are doing that in day to day operations.
So, I’m guessing the 737 door can’t be opened while the cabin is pressurized? Great video!
That’s correct 👍. And thank you.
can you please make a video about the training of emirates's flight attendants i am a new joiner and i would like to have an idea about it THANK YOU
You are asking the wrong person and on the wrong channel. This channel is about aircraft maintenance. Not flight attendant at Emirates.
@@StigAviation "I appreciate the insights you provided. They clarified things for me."
When Boeing created the 737 Max, why didn't they update the door? They have updated the over wing exit to swing up and out.
The max was modified to its maximum extent, if they changed anything more, it would no longer be a 737. They had to keep the doors the same and upgrade different systems.
Next time they take too long to board I’m pushing that button. 😂
🤣🤣🤣
Boeing Is coming out with a new screen door😂
Oh goodness 😅😂
Metoo....
Worstslide i ever changed in my life was airbus
Yes it is a pain to do it. The lacing on the gurt bar is a bit convoluted
