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.
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 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.
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
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.
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
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
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.
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.
@@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.
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.
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
@@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.
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.
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.
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
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.
@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.
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.
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.
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. 😕😝😜 👍🏼
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.
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.
@@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.😊
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.
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 🤣🤣
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❤
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!
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
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.
Seepage. The wing is pressurized, and also goes through variety of pressure changes and temperature changes. Expanding contracting, the seals seepage occurs.
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.
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 .
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. 🤣👍🏻
What do you think happened to Alaska 1282 losing the plug? NTSB also reported the depressurization lights had come on 3 times prior to the accident. How can you all check that?
I believe the news is already out and it was a case of loose bolts that hold the plug. As for pressure checks… we can perform pressurization on the ground. Basically seal the aircraft and pump it up using the air conditioning system
Im just glad no one was seriously injured or worse. Shouldnt the pilots have written up the indicator lights coming on especially since it happened twice while the aircraft was on the ground? Would that be a reason to ground the plane from service until the issue was corrected?
@@stevec7793 in my opinion yes, the Pilot should’ve written it up, or maybe they did and whatever procedure they performed, corrected that issue at the time. Once again, I don’t know all the details of what transpired with that aircraft. So it would be purely speculation, and, I cannot speak on something I don’t know, that would be unprofessional of me. That’s why I say I will wait for the official reports.
It’s not too old. I know many people that started this career in their 30s and 40s. It takes 2 years or 18 months of schooling and FAA tests at the end. The license/certification needed is the Airframe and PowerPlant license.
They have a location on the airport, called the fuel farm, it’s basically a huge storage facility for fuel that feeds the underground piping to various terminals.

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.

Glad you are enjoying it.
Great channel, I really enjoy watching and learning as an aircraft enthusiast.
Thank you very much
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
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 😅
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?
Very informative as usual. Thanks gentlemen 👍
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
Awesome video, Stig. Nice collaboration with a fellow Canadian. 😎🇨🇦

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
Another great job, Stig, thanks!

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

Also could the rudder be moved with elec trim if all hyd has failed?

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.
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.

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!
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
What a great channel.

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.

Busy as heck. And no issues here. We don’t fly -9s. Please do your research. We only have -8s

When dumping fuel, how many gallons per minute is the flow
With both nozzles active it can dump around 3000 lbs per minute.
Thanks good job
Thank you
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.

is there any left over fuel in there now ?
Yes most times there’s left over fuel when the aircraft lands
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.
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.
Thanks man!!!!
My pleasure 👍
Note in some aircraft gravity fuel feeding is only possible from wing tanks (and not main tanks).
That’s correct 👍
Your soundtrack reminds me of my childhood listening to”today on how it’s made”
Best show ever 👌
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.
10:12 - They are germicidal UV lamps. Do you wear eye protection for those!?
Inside the tank. Yes absolutely.
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.
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 😂
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
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.
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
What do you think happened to Alaska 1282 losing the plug? NTSB also reported the depressurization lights had come on 3 times prior to the accident. How can you all check that?
I believe the news is already out and it was a case of loose bolts that hold the plug. As for pressure checks… we can perform pressurization on the ground. Basically seal the aircraft and pump it up using the air conditioning system
Im just glad no one was seriously injured or worse. Shouldnt the pilots have written up the indicator lights coming on especially since it happened twice while the aircraft was on the ground? Would that be a reason to ground the plane from service until the issue was corrected?
@@stevec7793 in my opinion yes, the Pilot should’ve written it up, or maybe they did and whatever procedure they performed, corrected that issue at the time. Once again, I don’t know all the details of what transpired with that aircraft. So it would be purely speculation, and, I cannot speak on something I don’t know, that would be unprofessional of me. That’s why I say I will wait for the official reports.
True. Keep doing what you do. Love the content!!!!!!
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.
Tank diving is cool
It’s definitely an experience.
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.
Awesome
👍
Hi Stig! What's the path to becoming a maintenance engineer? Is 35 too old to begin studies? 😢
It’s not too old. I know many people that started this career in their 30s and 40s. It takes 2 years or 18 months of schooling and FAA tests at the end. The license/certification needed is the Airframe and PowerPlant license.
@@StigAviation thanks 😃
I love American Airlines - AA
Thank you 🙏
What about airport fueling systems and storage. It must house and resupply massive amounts to fuel all the planes daily.
They have a location on the airport, called the fuel farm, it’s basically a huge storage facility for fuel that feeds the underground piping to various terminals.
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.
