I don't think any other channel does what you do. Love the content.
And no other channel will. I’m giving you real raw knowledge from first hand experience. Not some commentary from a pilot or news anchor. I’m a mechanic. I show you what I do and how it’s done. Real data and information from someone that does the job.
I thought AA retired the A330. Are they still in the fleet for charters or something?
Btw keep up the good content. Love it!!
That was old footage from when they were still in service. They are all decommissioned now.
I can not find a channel like his! Absolutely love the channel!!!
Man never stop making these videos. Haven't found any such live in depth explanations anywhere on youtube. It's a treat for mechanical engineers like me!
I’m very happy you are enjoying it and hope it’s helpful.
I worked in emergency services in Upstate SC. Lockheed has a facility in our area (now they build the F-16 there). At that time, they had the repair contract on all the Air Force KC10 tankers. They allowed us to practice confined space rescue in the wing structures of these aircraft. Despite their size, it's still difficult to move around when you're kitted out with respirator and supplied air lines.
Most definitely very difficult, here’s the interesting part, getting inside the tank is actually not that hard, moving inside and maneuvering through the baffles is a nightmare, especially when you start getting to the tips of the wings. And the most difficult part is usually getting out of the tank.
I love this channel so much, I didn’t think I would enjoy watching plane maintenance this much, but I guess I do and I really hope you keep it up ❤
Thank you Andre. I’m very happy you are enjoying it.
Sees notification that stig uploaded, leaves first child's birth to watch. 😂
Love the how it's made music too!
Ohh my goodness 😂. Go back to the kid. Stig can wait. 🤣.
@@StigAviation remember stig, sacrifices!
Also stig like always love the videos as an aspiring aero engineer and pilot I really love your videos it’s really helpful for niche details and knowledge. Can’t express how thankful I am for you :D
I’m so grateful that you are here and leaning and enjoying it all. Thank you
Your videos are fantastic! Addictive! Fascinating! Well done, thank you!
Many thanks Jean I appreciate you being here.
Amazing to see how much room there is in that wing Stig and structural bracing and thank @only_fancowl for explaing the fact they can trim the airplane using fuel as well as control surfaces. I still look at my photos of 787s and think the wing flex is so cool yet so strong. Stay safe stig
Thank you Chris. And that 787 wing flex is just pure magic 👌
Thank you Stig! Great to see you collab with another creator. You are growing super fast on CZcams, don't forget me when you're famous!
I never forget anyone Dean. As long as you talk to me I’ll be always talk to you. And you know me.. I don’t look at numbers.. I just look at the people here and try to talk to everyone
Thanks a lot Stig, It means a lot to hear that
Hey Stig, I found the ratcheting open ending wrenches you showed on your tool video. Had to enlarge a frame of the video to read “Alden” on the wrench. Found out they were originally called Alden wrenches (named for their inventor) but that company is no longer in business. After some patent fights, I believe Chicago Brand (Medford OR) bought them out and currently make them. They are still polished stainless steel, so no chrome chips to worry about as you mentioned, but are not quite the same quality as the old Alden ones. I bought a set as soon as I saw your video. Thanks for making me aware of them. They are perfect for tight spaces and so much easier to use since you don’t have to take them off and on the nut or bolt. Just Google Alden wrenches. Your videos are highly informative and your attitude is infectious. Keep up the good work keeping us all safely flying.
Thank you so much. I’ll definitely look that up. And I’m glad you are enjoying the wrenches.
Very informative as usual. Thanks gentlemen 👍
Thank you for watching
Thank you for sharing aircraft workings.😊
My pleasure. Thank you for watching
@@StigAviationYes, flying our aircraft is very very interesting all the time. I miss the recently retired 747-400s from my former airline's. Yes, I use to look out at the left wing from door 1L all the time.😊
Excellent video!!👍✈️
Thanks a lot!
Excellent videos for aviation buffs who are fascinated by these big jets!!!!!
Glad you are enjoying it.
One of the Best aviation channels out here in CZcams!!!
Thank you very much. I appreciate you being here.
The the “How It’s Made” background music.
My favorite show 👌
Kool stuff. TY Stig. ✈️
👍
I appreciate the opportunity to learn more about aviation from you, thank you for making these videos 😎🙏🇨🇦🇺🇲
My pleasure James.
so fun to see the video on wings, it's my specialty, i've worked wings as a structure mechanic for many years. you can walk around in a 747 wing almost standing straight up.
Yup. Same in the center tank. Heck I can’t even jump and touch the ceiling in there
Great channel, I really enjoy watching and learning as an aircraft enthusiast.
Thank you very much
amazing work my bro
Thank you sir 👍
Thanks a lot thee only one aircraft filming......❤
Thank you
Good content Stig!
Thank you Kenny
I have been proudly in every B747-400 fuel tank from the huge center tank where you can play cards 🃏 to the small coffin size tail tank and the outer vent tanks. It took always some time to get rid off the fuel smell aka Chanel 28 😂
That fuel smell seems to linger on forever. I got drenched a few times in my career… I tell you what… not only the the clothes go straight into the dumpster… but after about the 15th shower.. I can still smell it 🤣🤣
@@StigAviationDior Fahrenheit 😂
The How It's Made soundtrack is throwing me for a curve lol. Love your vids, Stig!
One of my favorite shows. Glad you enjoyed it
Awesome video, Stig. Nice collaboration with a fellow Canadian. 😎🇨🇦
Thank you sir. It was a pleasure to make this one.
As usual you show a part of the airplane that is not seen by 99.999% of the people. I would never have guessed just how much bracing is involved with the tanks. I always thought that there was some type of fuel bladder in the wings, thanks so much for the tour. 😊
Glad you enjoyed it Bradly. And yes indeed, very few people will see the inside of a fuel tank. As for bladder style tanks, those exist as well on different aircraft.
Very cool! Having fueled for a few years, this interested me! Love the “How It’s Made” background music 😂
It gives you a perspective of when you are pumping fuel into the aircraft and where it’s actually going. Pretty cool, right?
I like your Channel , very informative
Thank you very much. I appreciate you being here
The how it’s made music! Good stuff!
One of my favorite shows
@@StigAviation it was the best! Shame I can’t find anywhere to watch full episodes anymore
This is the first video I saw that unravels the mystery of inside structure of a aircraft wing.....a masterpiece no less than that of a bird wing.salute to the engineers team that design develop and manufacture.
Indeed it is a marvel of engineering. I’m glad you enjoyed it. Thank you for watching.
Old stingy doesn’t disappoint.. wonderful informative video
Thank you Mahj
Thanks man!!!!
My pleasure 👍
Thank you for this and to your Canadian friend :D
Our pleasure!
I just realized you used the how it’s made background music 😂 love it !
Best show ever made 🤙
@@StigAviation I can agree 🫡
Thanks good job
Thank you
I love your videos!
Been reading conflicting info about the a320 mechanical backup. Do the rudders and THS have cables to them, only 1 or neither?
A320 family have a cable but they don’t actually touch physical flight control surfaces. They touch servos. So pure fly by wire system. But it’s a quadruple redundancy system
@@StigAviation Thanks. So both the THS and rudder do?
Also could the rudder be moved with elec trim if all hyd has failed?
@@pilotboy2612 you got it. All FBY.
@@StigAviation Much appreciated
My father said you should learn something new every day, he would be very proud of me today.
Thank you 👍🏴
Your father is a very smart man 👍
@@StigAviation
Your your knowledge of all the different aircraft that you work on is just awesome.
I enjoy all the details you go into. Keep them coming.
Love the technical vids can you do one on the weather radar or maybe the autopilot :)
I’ll try to put that in the next batch 👍
Awesome
👍
That was AMAIZING!! I never realize these jets too you have to manually sump the fuel tanks for water or sediments!
Yup. Just like a Cessna the big ones need sumping too
The background music was a good choice... 👍👍
Thank you Sir. How it’s made is an amazing show
The A-380 wing and fuel tank structure are amazing. Would love a walk around on that fuel system.
Would like to see that myself as well
5:57 the Delta flight you’re talking about was an emergency, yes, but the pilots were asked twice by ATC if they wanted a pattern over the ocean to dump fuel. They said no and then proceeded to dump approximately 60,000 litres of fuel over densely populated LA, resulting in 56 injuries. It was avoidable.
Pilots have final say on it. They must have a good reason for doing it over the city
Excellent Stig thanks.
Sumping fuel is the same as in GA.😊
Thank you Sean You got it right. Sumping is standard across all aircraft. Major or minor
That was fascinating!!! As a n airplane nurd I want more. Great videos l!!!!!!
More to come! Thank you for watching.
Lots of room in there. The tanks I worked in were much smaller, but so was the aircraft. A&P retired enjoy all of that new tech. Wonder what it will look like in 50 + years. Thanks for the tour.
Maybe in the future is will transition into fuel rods or some sort of electric source of fuel.
I like the how it’s made music!
I Love that show 👍
Love the how it's made bg
One of my favorite shows 👍
@@StigAviation same it's really catchy :D
Stig u are a legend ❤
I’m just a wrench 🔧 but thank you for the kind words.
Thanks Stig , great as usual. Stig would love to hear your thoughts about the Alaska 737 incident any chance of a special about door plugs please.
Honestly it’s need talked about more by everyone else. I personally don’t work on the 737 max -9. Because we only have -8s. As the news states, they found loose bolts that hold that plug.
I heard a general aviation pilot mention sumping as very important for each fill up. This prevents potential loss of power due to particulate matter, or like you mentioned, water. It was mentioned in the review of a flight that lost power on takeoff after some engine work. The aircraft landed fine in a field.
This is a standard between all aircraft, they all need to be sumped.
What a great channel.
Glad you are enjoying it John 👍
Another great job, Stig, thanks!
I worked on a many 727’s and they were notorious for crappy fuel quantity systems…. Always on MEL. So we got very good at drip sticks and taking a jet fuel bath 😂
Chris remember the classic gravity fueling for those 😅. The darn thing still have the fuel cap on top of the wing 🤣🤣🤣. That was always fun to walk on the wing to inspect it.
I remember it well! Safety harness? What’s a safety harness 😂😂
nice to see the inside of a wing again. I'm too chubby to get inside anymore, that is also nice. lol
Once you been in one … you don’t ever want to get back in one lol 😂
Great vids Stig! I can tell you, you haven’t lived until you get the chance to replace a FQMS probe wire harness on the inboard wing fuel cell of a G550. 😕😝😜 👍🏼
Oh my lord 😅 I have heard horror stories about those corporate jets. You better be very small and a contortionist to be able to do that job 🤣
Stig I’m on it now
Excellent video. I learned a lot ✈️⛽️🙌. Bryan SFO
Thank you Bryan. Much love from LAX to you
Gonna put in my application. Can I use you as a reference? 🤣
Great job on these videos.
References only per STIG 🤣🤣🤣
Another extremely amazing video
ABSOLUTELY love it
Here i am thinking aircraft had great big rubber bladders in both wings and in the middle also.
awesome stuff
Thank you. Glad you enjoyed it. Glad you mentioned the bladder style … there are aircraft that have that as well.
@@StigAviation 😂😂 Just discovered there is 4 different types of tanks
Bladder style
Tip tank
Rigid removable tanks
And
Integral fuel tank.
So I guess from what I seen pretty much all passenger aircraft have integral tanks and have never had bladder tanks.
Only small Aircarft and the airforce and i guess some helicopters also.
I seen on some TV show it MIGHT have been Dirty Jobs with Mike Rowe years ago lol.
They pulled a old bladder out of a wing and replace it or repaired it.
I know the airforce also use them alot for transporting the fuel AND in aircraft tankers for mid air refuelling.
@@johnnyo7621 you’re absolutely correct John, but here’s a little interesting thing, the Airbus also has additional center tanks, we called them ACTs. Those actually have a bladder inside them, don’t ask me why they did it like that but that’s how they designed it.
@@StigAviation 😳😳 Goodness now you got me thinking Stig.
Trying to think if you ever mentioned it before since you have pretty much covered just about everything on passenger aircraft lol
@@johnnyo7621 I have barely scratched the surface on commercial aircraft. There so much more involved in the things I talk about. Remember, I simply open the door for you. You get to walk through it and dive into the rabbit hole. Endless amounts of knowledge and information out there.
I learned a great deal and it is probably very basic information to you! Thanks so much! I never saw fuel dumping, or fuel access, or the sump procedure, as well as manual checks on the fuel level. It is fascinating the fuel can be used to trim, on some aircraft. I bet that saves on gas mileage.
I’m glad you enjoyed it, thank you for watching
Great information, just one question how does fuel in A330 do a trimming. Is it flt contrls, engine trimming?
It’s simply transfer of fuel to balance the aircraft CG (center of gravity).
@@StigAviation Thanks Stig
I love what you do it’s amazing, by the way I could have an interview in two weeks in LA any advice? Do you have any idea about the interview could help? My best❤
All I can tell you is know your basics. It’s the same as your O&P
Gotta check for LEL's (lower explosion limits and purge before entering.
Tank diving. A BigBux, nasty job crawling aroung cleaning, inspection etc. ReaI cramped in there - ribs; stiffeners etc.
Definitely not for the faint of heart 😅
I have a private pilot license and taking a fuel sample was something I learned to do during my very first lesson. I had no idea that the heavy jets had sumps in the wings. I've never seen a passenger jet pilot taking a fuel sample during their walk around, so I have to guess it's not a part of their pre flight routine at the airlines? And by the way, you couldn't pay me enough to crawl around inside of those fuel tanks...much respect to those that do it to keep us safe.
It is part of maintenance checks and done by techs.
Yup all aircraft have sump drains. And that’s maintenance responsibility on major aircraft. Crawling into one of those tanks is a different level of maintenance, it takes a special kind of mechanic for sure.
Tank diving is cool
It’s definitely an experience.
It's interesting that one time I was watching a video that they said the 747 had a center tank that was almost as big as a two car garage, and all the while, he said that I kept looking at our garage trying to imagine. Another good video by the way.
The 747 center tank is truly that big. How do I know, because I have been in one. I’ll give you a perspective… I’m 5’6… when I was inside of it.. I couldn’t even Jump and touch the ceiling of the tank. I needed a ladder. It’s huge
Your soundtrack reminds me of my childhood listening to”today on how it’s made”
Best show ever 👌
How does the air inside the tanks get vented off while fueling? Is there like a fuel vapor capture device like the evap system in cars?
Via the vent valves. Under side of the wing has vents. And also in flight the NGS is being feed via the air conditioning system
Would be dope if you could give us a Stig take on 737 max plug doors and what your experience is with them
Well I work in the 737-8 max. Those don’t have that plug. As for my take.. there’s nothing new for me to say about it that hasn’t been already said by the news.
Question: you said that if the fuel pumps become inop it will still work with gravity wich makes sense for me when it comes to planes that have their engines under the wing. But what about planes with engines on the tail since the engines are above the wing? Or on tri-jets like dc10/md11 or l1011 would engine 2 just quit?
Anyway another amazing video as an automotive mechanic and AV geek its so cool to see how things work. Keep up the work man!
Those are a bit different, those aircraft will use a Venturi style suction to get fuel to the engine.
@@StigAviation interesting. As always thanks for the information!
Love your videos. Inside they look like inside of a warehouse with sheet metal. Why not have a rounded tank with smooth edges
Well the wing structure wouldn’t allow that. It has to be angular
@@StigAviation ahh thats a good point.
I wish there were such channels back in 2008 when i was doing my engineering........now i am stuck with the construction industry work even though i am an aeronautical engineer
Trust me I wish I this kind of stuff too when I was going to school 25 years ago
what were all the black streaks coming off the wing access covers?
Seepage. The wing is pressurized, and also goes through variety of pressure changes and temperature changes. Expanding contracting, the seals seepage occurs.
Note in some aircraft gravity fuel feeding is only possible from wing tanks (and not main tanks).
That’s correct 👍
I was hoping for a longer video Stigi! :(
This one was just an educational one. I’ll do longer ones in the future. Hope you still enjoyed it tho
My sister is a rosie the riveter at Boeing and shes built dang near every 777 wing.
She even Boogered one up. She put a template in backwards or sumthin.
One of the airlines got a big price break on a wing.
Im proud om my sister. She has never Illegitimately missed a day of work in her life from the time she started babysitting at 9 years old to this day.
I would be just as proud. That’s true dedication right there
Mistakes happen to everyone. Fortunately, the template was discovered. Too bad the door plug installation error on Alaska wasn't detected.
@@ImperrfectStranger that situation stinks to high heaven. My sister and her coworkers from what I've been able to gather are all extremely competent.
@williambarry8015 Competent people can still help the holes in the Swiss cheese line up. What factors made your sister put the template in backwards? What made me blow an escape slide by accident? Environmental factors, paperwork errors, training errors, lack of crosschecking, etc. Loose bolts were found on other 737's, but some of those bolts may have been put in at Boeing's subcontractor and other bolts on the main assembly line in a different city.
@@ImperrfectStranger you pulled an emergency by slide by Accident?🤣🤣🤣🤣🤣im laughing with you. Thats an awesome oopsie.
Do any aircraft have fuel in the horizontal stabilizer? I think it might have been an option on the 747's.
747 has the option. 330 also does
@@StigAviation Looks like the A380 does or has the option as well. Thanks for the video.
Stig, on some airlines. They paint the tip of their flap track red. What's the reason for that? (For ex, Singapore Airline)
Just extra visibility.
Great video. How busy are yall with a 737 max with what happened.
Busy as heck. And no issues here. We don’t fly -9s. Please do your research. We only have -8s
Do you and your team also fuel aircraft or is there a dedicated crew for that?
There are fueling personnel that do that job. That’s separate from maintenance. Maintenance can do it as well but if we are doing it, it’s for maintenance purposes.
Great video! The fuel management was impressive. I notice they didn’t let you film the chemtrail distribution equipment - further proof it exists as if we needed any!
Sorry. 🤣👍🏻
Chemtrails 😅. Shuuu 🤫 that will be our secret 😂
Is there any particular reason why the refuel starts to slow down when it’s about to finish ?
I haven’t really noticed that, usually it just cuts out at the preselected amount. Might be because the tank is reaching it capacity
Please Stig , i want you to make a video on every Type Aircraft starting from A320 , to B777 , B787 . Show us how to do Wheel change , Hydraulic Service, Daily check , IDG , Engine servicing etc .
That’s a lot of videos you are asking for, which I have most of them posted. Please feel free to check out the other videos I have.
Yes, sir Stig it’s called suction feed when the engines are running they will stack fuel out of the tanks even with no fuel pumps operating
You are absolutely correct my friend. I was just trying to simplify it. But you are totally right
... with no *tank* fuel pumps operating. There are still fuel pumps on the engine.
Didn’t know stig is in LAX, I literally work at one of the aerospace factories across the the street
That’s awesome, El Segundo got some good restaurants too, right
10:12 - They are germicidal UV lamps. Do you wear eye protection for those!?
Inside the tank. Yes absolutely.
I hear the Mythbusters music backing track
How it’s made 👌
Which flashlight are you using? Very visible during daylight
At the moment a ThruNite TT20
When dumping fuel, how many gallons per minute is the flow
With both nozzles active it can dump around 3000 lbs per minute.
Stig, would you please show us what component failed in the Alaska Airlines 737 and caused the loss of pressurization? Thanks.
My friend it’s already out in the news. The bolts that hold the plug. I don’t need to make a video or explain it when it’s already done.
@@StigAviation what plug are they talking about?
The things that actually blew out is a dummy plug. They have an option to have a door there, depending on seat configuration.
Stig I am doing something completely ridiculous designing a jet engine anything that incorporating it into the engine would help it function. 😁
Would love to see your design
Hi stig what is the minimum quantity of fuel that can be jettisoned? Is it possible to jettison fuel if remaining fuel in the center tank is 200 kg during flight? Center fuel tank pump Low pressure light illuminates if there is low fuel in the center fuel tank.
I’ll be honest with you I can’t remember what’s the minimum amount. I would have to look that up. As for the center tank, the fuel from the center will be pumped into the wings regardless of jettisoning from the wings.
@StigAviation okay stig. I had this question in my mind, I thought to share it.
Dove in a tank on an L1011 once. Glad I never have had to do it aagin.
It definitely is an experience to tank dive, some enjoy it some can’t wait to get out of it 😂
I know lots of guys who have no problem with it being tall doesn't help either
@@StigAviation
I love American Airlines - AA
Thank you 🙏
How is fuel flow controlled if gravity fed?
You should watch my latest video where I do an engine breakdown. I explain there that the engine has a fuel metering system
What percentage of the total fuel load is stored inside the center tank?
It depends on the type of aircraft, but I would say around 40%
@@StigAviation So on a larger twin aisle plane such as 777, the center tank could easily hold more fuel than a long fuel tanker truck.
What the mechanicals that operate the flaps?
Usually torque tubes and angled transmissions that move the flaps up or down the carriage all powered by hydraulics or electric motors.
Why do the wings look so much smaller outside than the tank inside? Is most of the tank in the center section?
Probably because of how you view the aircraft. The closer you get the more massive it is. The tanks are in center and extending through the whole length of the wing.
the tank looks bigger inside than on the plane. those tanks were empty correct. i assume if full he would be wading in fuel?
Yes of course. They drain the tanks and vent them out before entering.
Lets remember the fuel heaters as the fuel goes to the engines. BA 777 froze its fuel and landed short of the runway at heathrow. Just one of the many components people know nothing about.
Well the 777 is very special.. it actually has a hydraulic fuel heat exchanger inside the wing tank itself.
