- Opening Cowl and Thrust Reverser on Boeing 777 Engine GE90-90B
Opening the fan and core cowling on a GE90-90B Jet engine. The fuel filter was changed and this requires that the engine is then run followed by a visual check to make sure there is not fuel leaking out of the fuel filter canister.
The fan cowl are the doors toward the front of the engine. They are held closed by 4 latches across the bottom. The core cowl are toward that rear of the engine. They also house the thrust reversers. The core cowls are held closed by 13 latches that must be released and then re-latched in a specific order. You will notice in the video that I count the latches prior to using the power cowl opening system. The opening system is powerful enough that if a latch is missed it will be possible to break the strap mounts.
Thank you for NO music. Loved all the sounds...
Yes I agree....... Great comment Faraz 👍
Yes, this beautifull sound of frying pan dragged on the concrete)
kecelakaan tol cipali
Agree..... And none of the BS of 'if any of the latches came undone in flight the entire aircraft would crash type of crap'
With stuff like this the sound is just as important. When I'm seeing something works I want to hear it too! No music
Doesn't matter how high you raise an engine off the ground-- a mechanic will still end up on their backs to work on something.
That's Murphy's law, drop a tool and it rolls out of reach,🤣
These guys are the unsung heros of flight travel. He only has to miss something and the consequences are un unimaginable. Great watch. Just pointing a camera at these guys at work is all the screen entertainment I need!

In 1991 i started working at JFK as a ramp worker. The engines didn’t have actuators. All manual, and a 2-3 man job opening those things for maintenance. Unless a quick check, meant that plane was grounded for a few hours. Come a long way 👍
Cheers for that Paul 👍
people like him that make flying safe but are so dedicated to make sure everything is locked up tight and correctly
Tom William No shit Sherlock....
I heard that the technical documentation for a 747 (yes this was a 777) weighed as much as the entire aircraft.
Imagine all the parts and assemblies... all the manufacturing specifications, design drawings, assembly details, test documentation, maintenance instructions, troubleshooting guides, checklists, engineering change approval/documentation, process tracking ... Of course, much of that will be digital today.
I never cease to be amazed ... and impressed by engineering, technology and competence.
Thank you for sharing this for us.
Legend has it, he's still pulling levers.
Specially the one before the last one is giving him a hard time securing the latches
Crazy how close the engines are to the ground. Looking at planes from a far, I never really noticed they only really hang about 4 ft above ground until seeing videos of people up close with the engines.
I love the lying on your back maneuver where you push the doors closed with your legs and secure them with your hands!
One false move and off comes a finger, kudos to these highly skllled engineers who ensure our safety in the air.
Real hero...maintenance personel. Everbody must kiss their hands.
Complex piece of machinery for sure,and amazing how it all works
Thanks for showing✅
I`m 46yrs old and I wanna go back to school for aircraft maintenance. SO awesome to be able to work on them giants
Do it!
BigIronTV Is it hard to learn. I`m sorry but I`m a little negative, always been. I heard that there is a final verbal exam. I have a slight stutter I hope I manage the stress at that time.
It requires effort but not harder than learning anything else. There are two certificates available. One is the Airframe and the other is the Powerplant. Some people get one and not the other. This will greatly limit your work options though so it is best to get them both. The testing process is that you are required to complete either on the job experience or a certified training program. From the OJT you will get someone that is qualified to verify in writing that you have the required OJT. From the training you must pass the test at the end of the course. With either the OJT letter or passing test score you then go to the FAA and request permission to take the certification test. They will issue the permission and then you have a limited amount time to schedule and take the test. If you do not do the test during this time then you will need to reapply for permission to test again. Once you have the FAA permission to test you will need to find a designated examiner and schedule a time for an Oral Practical exam. For the oral part the examiner will sit with you and ask question of their choosing from a list of topics. If you do satisfactorily on the Oral then they begin the Practical exam. This is hands on where the examiner will tell you to accomplish specific tasks and then observes to see that you know how to find and use the correct reference data in the manuals and can follow the manual instructions to accomplish the tasks.
BigIronTV The oral part of the exam already scares me because I have a slight stutter. How often does an airplane require body work? I`m sure the other mechanical parts do so.....
BigIronTV Is the oral exam in front of the class or 1 on 1? I`m really nervous about it considering my slight stutter.
Damn this mechanic looks so profesionnal ...
(no dungarees or overall, no cap... just some gloves )
Incredible how complex these aircraft are,
This guy obviously knows his stuff
Os conectes on The Apu or batery DC?
@Demo show us yourself doing it then if it's that easy, and tell us exactly what he was doing every step of the way.
@Demo there's one in the video. use that one.
I hope so.
@@halowraith1 isnt this video pretty much instructions tho, and why would he need to know all the parts for?
Power liftgate, this must be the premium trim level
🤣
Crazy how big everything is on a plane! Almost all the planes I have flown on were tiny!
+Flint and Steel Survival Actually these are the largest jet engines. Most jets do not have engines this big. They are GE90-90B engines. Also I am small so that makes them look extra big.
what about the ge 90 115bs?
Referring to physical size.
BigIronTV
So do they have the same dimensions but instead of putting out 115k thrust they are simply derated to 90k?
Very similar in physical dimensions but quite different inside. More that just a derate. The GE90-90B that we have can be upgraded to a -94 www.geaviation.com/press/ge90/ge90_20010510.html. en.wikipedia.org/wiki/General_Electric_GE90
No wonder these damn engines cost millions of dollars a piece ! it must be a nightmare keeping these awesome machines running properly
I like how the 777 cowl doors are electronically controlled unlike the ones on the A330
I am glad to see it is not easy to open it.
DANG,....it ain't like poppin the hood on a grocery getter,...that's for sure !! Nice vid.
You really have to want to get in there to go through all of that. Thanks
You got to make sure those latches lock into place if not got to get sheetmetal mechanics involved or due a light repair to it
LOL
Cool vid! I did not know they have actuators on the cowls.
+MrBen527 Thanks
I would think you need them with the size of the engines on the Triple 7.
OOOOH GOD WHAT A GREAT JOB UR DOING WELL DONE AND GOD BLESS YOU YOU GOT A SUB 🖒🖒🖒🖒
The process is opening in on or by company off APU????
This is totally fascinating! Thanks for the upload.
I feel for the pilot for his preflight check.
thank you for the tutorial, now i'll be able to repair my 777 engine as well
Attention airlines, make sure that man is paid well.
0:20 Looks like he's gonna steal it ^^
Thank you for the highly technology grandsons of Jafeth.......you're blessed people......God bless you...

Qué buen vídeo!que capacitación este hombre,sin dudas una gran responsabilidad,nada puede fallar
Latches and levers could use some oil 😉😁 AWESOME VIDEO!
might be fire hazard or make stuff oily that aren't designed to be oiled, like damaging gaskets orings or seals... and might increase drag if it leaked out and streaked across panels
who knows, itd probably be fine, but the insurance of a sticky latch that needs to remain closed is calming
WD40
@@danielpratama2945 deep creep is better. kroil is pretty terrible for value.
Unless it is in the aircraft maintenance manual it is prohibited.
Thats why I started doing work out. This is my job and it requires strength. Im just 65 kg skinny guy.
Holy crap that engine is massive!
Very interesting! Thank you for sharing these videos!
You're blessed people indeed....Amen
awesome. thank you for the video
I think aeroplane is the greatest invention ever by human.
A very responsible job. Only needs one to come undone in flight
I really liked the video, thanks!
Legend has it, he is a good wing man.
I'm relieved to know that one latch doesn't hold the whole thing together.
Imagine opening that 1 latch and the engine dislodges from the wing, only thing remaining are the open cowlings still stuck to the plane Haha
That locking mechanism is cool thou
This was a most interesting video,thank you.Fascinating,those big jet engines,and they have a great sound too!
It amazes me how they can fabricate, assemble and get all of these complicated parts to fit together... And I have a mechanical aptitude in the 90th percentile! P.S. You can hear nearby radar blipping his camera's audio...
Sounds like some of those latches could use a shot of WD 40. Of course for the aircraft industry WD 40 would be relabeled with a twelve digit part number in a solid grey can and cost $45 a can.
Aerokroil it's $30 a can, it wouldn't surprise me if that's what they use.
Once a year they have a buy one get one free so that's how I justify buying it, but even at $15 a can it's still triple what most cost.
I don´t want to be too nit-picked, but this is not the way to open the cowls on a GE 90 baseline engine. The maual tells you to follow a specific order for the latches.
Markus Pristonig okay then
The correct order is not that important as long as you don't go just random. The T-handle (the smaller GE90 doesn't seem to have it?) operates easier when opened earlier in the sequence. What concerns me more is that he doesn't latch any of the hold open rods.
I was a mechanic and flight engineer. This is a first officer filling in for a mech. Dont know if he is qualified to sign off any thing.
I think you close the bifurcation latch and t handle before, I think they are the last to close
Well done for the workmen... speedy and correct!
Congratulations for video ! Wath is the reason of the inspection ?
not like car to open the engine but this beast opens with hydraulic wow
kvalitet slike je odlican Thank you for NO music. ..jasno pise filter goriva je zamenjen a ne ulja kao sto stoji u nekim kometarima
6 ton per engine ! Wow !
Masterpiece of engineering
I didn’t realise there was so much brute intimacy with ground engineers
was that rattling sound the inner turbines windmilling or something? thanks for the upload
Good job mr. A&P /AMT on 777 cowling/TR opening. ;-) thanks.
Good job 👍✈
Not sure which airline this is,but I am surprised that a chap is allowed to do maintenance work on his own with no checks or assistance.dont think id fly with them !!
I have a question, Why are airplanefans mostly running while the airplane is not in use? And the direction is different....when the angine really starts, than the fan stops turning and turns into another direction. Also in this video you can see the fan a little bit working....why is that? And thanks for the lovely vid!
Because of wind
It is the wind blowing that causes the fan to spin like a windmill. If the wind is blowing behind the motor it will spin the fan in reverse direction.
Wow. I have never seen this detail before. It looks like a hard job just to open it up and take a look. It is easy to forget just how big those powerful engines are. Every latch is critical and must be secured. At 10:25 : I was wondering, I that standard Boeing procedure to lie on you back and use your feet to close the cowlings? Was it planned to be that way?
Very interesting question, as the feet assist procedure requires some acrobatics skills XD
By APU in On or eletricall by system ?
They close like a barn door!
Attractive video ! Thanks for sharing.
Damn its easier to get to the oil filter of that jet engine, than it is in my car
Mahir Fredericks well that might be the case but your oil filter doesn’t cost hundreds of dollars.
1 oil change 2 million dollars, jiffy lube early bird , 39.99 😂😂
@@superskullmaster hundreds? that's a 50$ tractor filter lol
You hatch openin' dawg you
+aligory isostope Oh yeah
Lol
Piece of art machine.
What is the small protrusion on the under side of the cowling that looks like an exhaust pipe for?
+Geoffrey Gallaway Oil drain vent. Oil leaking around seals during operation is captured and directed through pipes to the vent so it does not collect in the cowl and cause fire hazard.
WOW!! way too much stuff to remember
Very interesting video, cheers mate!
You must have amazing arm strength
It’s funny that he does not have an assistant to help and even double check that everything is A-ok .
Hated closing these doors by hand on test stand .
Wow what an amazing insight Thank You. Looks like hard work just to pop the hood 😁 How comes so many latches?
Redundancy. If you see an excessive amount of things it's all about keeping you safe. ^.^
Who the heck designed this thing? Rube Goldberg?
Holy smokes, there is a lot going on there...
Very challenging,I like it!
Nice job
Amazing video thanks for sharing
Hope it's some reliable locking system on all those stuff he closed only by hand !!!!
Why didn't they just use Velcro?
That livery... Is that a private 777?
Great experience
Super cool
I See first time...its amazing video...realy amazing
That is 767 because it’s different land gear
Good job!😎
You closed revers in process on ?
Or dispers de off to apu?
Hey guys I'm here
Check the air in the tires please.
Most interesting....thank you!
Must have had to watch alot of utube videos on how to check on a 777 fuel filter
What exactly did u check?
i bet the purpose of this video , is a warranty for him. if something wrong or accident or somenthing like that , he has all recorded where his hands were.
He's a better man than I am. He doesn't need to go to the gym either.
I don't even work out! haha
They sure don't want those to open by accident.
That's not a 777...the under carriage for a 777 has got 6 tires per strut. This one has only 4 tires per strut
Is it possible to deploy engine thrust reverser accidently during mid flight? Such as on this B777?
Where is the run-up?

Wow very interesting and informative
