BREAKING United 777-300ER EMERGENCY LANDING at Sydney Airport March 11, 2024
ฝัง
- เผยแพร่เมื่อ 20 พ.ย. 2024
- Today, Monday, March 11, 2024, United's regularly scheduled UA830 777-300ER service from Sydney to San Francisco returned to the airport after a little under an hour of flying time. Upon arrival back into Sydney, the aircraft was met with an army of fire crew and police. On approach, the landing gear compartment doors could be seen wide open, as well as smoke coming from one of the tires on the right-hand side of the aircraft. Upon re-watching my footage, I noticed that on takeoff, the tire could already be seen smoking. It would appear that the crew didn't receive any warnings until well into the cruise, despite the issue being present at takeoff.
United has had a tough run of it lately, with all of the following incidents happening in the past week: a 777-200 bound for Osaka lost one of its wheels on takeoff, a 737max skidded off the runway in Houston, a 737-900 had flames shooting out of its engines after ingesting bubble wrap, an A320 made an emergency landing in Los Angeles after a hydraulic failure and news of a 737max landing earlier in the year at Newark with locked rudder pedals.
I hate to say it, but I wonder what will be next for UA. I get that a lot of this is out of their hands, but they are responsible for the planes they fly.

There was no fire on that aircraft - not after take off, nor on approach and landing.
It suffered what looks to be a hydraulic failure, probably from a breached hydraulic line on the right main gear.
The ‘smoke’ on take off was the hydraulic fluid spraying out.
That’s why the gear was extended by gravity, leading to the gear doors staying open but the landing.
You can see the proof of this after the aircraft had been parked for some time - a puddle of hydraulic fluid can be seen expanding on the apron from under the rear wheel area of the right bogie. The smoke coming from the gear at that time is from the hydraulic fluid coming into contact with the hot brake assembly.
A single hydraulic system failure is no major issue, but they would’ve been in contact with UA engineering straight after takeoff, who then would’ve directed them to return to SYD rather than continue for another 11 hours on only two hydraulic systems.
It probably was non etops compliant with 1 unserviceable hydraulic system
💯💯💯💯
@@davidwarren202 I can’t be sure about the B777, but I would be surprised if its ETOPS/EDTO diversion criteria was substantially different to the Airbus twins I’m familiar with. A single hydraulic system failure on its own, ie no generator failures/MELs, does not preclude ETOPS operation, irrespective of whether the ETOPS area has been entered or not. Whether it is wise to do so depends on the sector being operated. A trans-Pacific flight would best be avoided, as UA chose to do on this occasion.
I wonder why then after the taxi back one of the tires was smoking. I'd suspect a stuck brake or under inflated tire more after watching the whole video.
@@pjford1118 As I mentioned in my first post, that’s normal when hydraulic fluid (seen leaking into the tarmac/apron) comes into contact with hot post-landing brakes.
I'm now retired and flew the 777 at UA for over 20 years and never had one single inflight emergency. It is a great aircraft and the crew did an excellent job. As the saying goes all is well that ends well.
My son worked on these jets for a different airline for 5 years. (He’s now in Flight school to pilot them). Never was there an issue either.
Yes the 777 Has always been a great aircraft. Wonderful to fly on.
Diversity is our strength
What's your take on the recently manufactured BA aircrafts? Hearing lot of -ve on the recently manufactured planes. Specially the 737 Maxs.
Great record
The gear doors hanging open like that typically indicates the gear was lowered using the alternate/emergency method.
Interesting. I was wondering about that. Any reason why they would be using that?
@@NewYorkAviation The smoke to me seems more like hydraulic fluid spraying out of somewhere. If you follow that logic, then you have a hydraulic leak thats depleting the center hyd system. By the time you get the "LO HYD LEVEL" warning on the EICAS, you're about 30 minutes out over the Pacific, so you have to turn around and fly back 30 minutes, so now that system is nearly empty of hydraulic fluid except for the emergency fluid in the reservoir that's there for exactly this situation. Excerpt:
Landing Gear Alternate Extension
The alternate landing gear extension system uses a dedicated DC hydraulic
pump and trapped center hydraulic system fluid to extend the landing gear.
The hot battery bus supplies power to the pump and an oversize tube from the
center hydraulic system reservoir supplies fluid. The tube contains enough
fluid to do an alternate extension with an empty center hydraulic system
reservoir.
Selecting DOWN on the ALTERNATE GEAR switch releases all door and gear
uplocks. The landing gear free-fall to the down and locked position without
sequencing, and do not tilt. The landing gear lever position has no effect on
landing gear alternate extension.
The EICAS landing gear position indication displays the expanded gear
position indication when the alternate extension system is used. During
alternate extension, the EICAS message GEAR DOOR is displayed because all
the hydraulically powered gear doors remain open
@@NewYorkAviationI think the smoke is actually hydraulic fluid spraying out of the center hydraulic system. By the time the crew got the LO HYD LEVEL warning, they were already 30 minutes into the flight, so they had to turn around and fly 30 minutes back to SYD. The alternate gear extension had to be used from lack of fluid.

@@NewYorkAviation I think the landing gear area may have had a hydraulic issue/leak which forced the crew to do a gravity gear extension which made the doors hang open as well because of the force of gravity. You can also notice the gears were not tilted at landing which also suggest a hydraulic issue.
It appears that the spoilers associated with the Center system did not deploy on landing. Also to note, while nosewheel steering is powered by Center hydraulics, it can be isolated in the event of quantity loss and thus the airplane was able to pull off the runway and taxi to park.
We have to be grateful these aircraft have redundancy hydraulic circuits well done to the flight crew for getting back safely.
And well trained flight deck pilots
Just sharing you this, as Romans 6:23 says, for the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord. God loves you so much that he sent his son Jesus Christ to die on the cross to pay the price of all our sins. After 3 days after he died,he rose up from the dead. He will accept you not matter what you been through or have done. Accept the lord Jesus Christ as you lord and savior and ask forgiveness of all your sins to be saved from sin and have eternal life and not go to hell Jesus is our only hope for salvation and the if you don’t accept him you will not heaven and you will go to hell if you don’t accept Jesus✝️
@@YourboyEJ_loweYou can't just preaching a religion on a video about aviation.
You can't just threatened people with different religions that they will go to hell because they're not on the same religion as yours.
And most importantly, fix your grammar, it looks like a total mess.
@@CrystalWings12And then when they finally turn to Jesus and repent, "christians" will say "It's never too late to turn to Jesus!"
You can search up videos like "Islam converts to Christianity", expect to see at least ONE comment saying its never too late, better late than never.
@@BlueCreeperFromMinecraft I don't even know where did you come from and why did you replied to a 6 month old comment, but I don't want to quit my religion. No thanks, you can stay on your lane.
I saw this in flight today. I was just north of Sydney airport and the aircraft flew directly overhead about 3 min after takeoff. There was a trail of white smoke or fluid, from where I was looking directly upwards it looked like it was coming from the tail. It was unusual, like a wing contrail but off the tip of the tail. This explains it!
Tire explosion?
You may have also seen fuel jettison.
Looks like it was hydraulic fluid, don't breathe that stuff, skydrol is toxic.
Not on take-off.
@@2fast790If it was coming out of the tail it was likely the hydraulic fluid coming out of the landing gear wells and running down the fuselage until it breaks free where the tail sweeps up. Fuel comes out near the wing tips when they perform a fuel dump.
0:32 that actually looks like some type of leak coming from the gear, not smoke
on takeoff its hydraulic fluid , when parked it the fluid cooking off on hot breaks / wheel hub emitting smoke
Hydraulic Leaks
Looks like a line burst causing depletion of the center hydraulic system. That would cause an alternate gear extension. The smoke on lift off is probably aeration of hydraulic fluid. Smoke after landing is probably remaining hydraulic fluid dripping onto the hot brakes. The smoke dissipates as the brakes cool back down in the breeze.
Great explanation and systems knowledge.
Why would the brakes should be hot, if the plane ✈️ took off?
Took the words right outta my mouth and mind
@@MirceaGavris Did you miss the bit where the hot brakes was associated with "smoke after landing"?
This time it’s not Boeing’s problem, but United Airlines maintenance issues
Yep as you can see the hydraulics leak at the landing gear door
I agree since all the incidents with Uniteds planes people just this it’s Boeing fault. The plane is also 6 years old!!
UA service having issues lately, that and the pilot trying to take a turn at 25knots vs the SOP 10
@@AidenLegends10
This is the only incident I know of for United the others were American Airlines.
Only the door issue was Boeing's fault of all these recent aircraft issues, (it should be noted that the fire was an Airbus), and even then Alaska shares much of the blame for letting it go so long even though they knew something was wrong.
Weird how this never made it onto the news, too much interest in dodgy bad Royals photo edits
Because it’s not really newsworthy. The plane had an issue, the pilots obviously declared they needed an emergency landing and they landed the plane. There are redundant systems on planes for this reason and no one was probably ever in danger.
Saw your comment & realized I’ve seen LOTS of your vids. Just subbed.
And YES, this should have been in the news. At least they reported the very suspicious death of the Boeing whistleblower.
I saw it on the news in MEL. Can't remember which channel it was on.
Is it an unwritten collusion between airlines and news media to not report such things 1. Because they will influence the financial viability of the Airline Companies. And 2. Associated it will freak out passengers about air travel and using the particular Airline concerned!
Either United's problems are previously being under-reported, or they are seemingly suddenly having an unusual number of problems. Be assured that luck has nothing to do with it.
It's spring break in US for a lot of folk, so there's an increased volume of flights. More flights, more potential for problems.
After the door issue on Alaska (and combined with MAX horrors), anything bad Boeing related gets news.
After the tire issue (which is very unusual failure and rather dramatically with it bouncing down a runway into a tesla), which is looking to be a manufacture defect and not United's fault, anything bad United gets news.
The engine failure is also looking to not be United fault (bubble wrap?), the rudder issue appears to be Boeing or manufacture, runway excursion looks to be pilot err/weather/atc.
Hydraulic failures aren;'t super super uncommon (based on binging atc/plane incident videos), and thus why there's multiple hydraulic systems on planes so they can land safely as it did here and Friday. These situations just usually don't get into national news, but do since got combination of United+Boeing, they do (tho the hydrlic on Friday was United but airbus, not Beoing). Important to look at this issues in context and not overly dramatize/worry .. .though the boeing door issue and negligence, that likely does deserve the drama/worry.
That’s because Boeing went WOKE and now they’re a JOKE.
Sabotage ? I hope not.
well did u see the videos of the CEO, and it's hiring priorities? 😅
@@linanicolia1363No but that’s weird it’s specifically with united that it’s happening a lot lately, maybe there’s an underlying issue behind this
These things happen. The pilot and crew did an amazing job to keep everyone informed and calm. Great work.
well, at least none of the wheels fell off this one....
Lol
Didn't get stuck in the grass either.
United is having alot of bad luck lately. Too bad it is with Boeing aircraft.
Smaarrtt aass ! Wise guy huh ?
The female fire fighter in yellow helmet is learning how to handle a big spewing hose !
Careful Joanie - that thing will get you in trouble ! She had male supervision - “ coaching “😅
Great footage, mate but please invest in a fuzzy mike cover, wind is loud.
The internet + LiveATC is half the reason we know about all these things. Seems like systems working as intended, lost 1 system, have 2 backups, decide to return to take a different plane. Seems like the real world where pre-internet we never would have heard about it.
I flew 747s as flight crew for BA back in the 1970s - pre internet - but never experienced these sorts of problems.
English... While I'd say people took more pride in their jobs back then, i have a hard time believing BA never had any in flight system failures or mx issues... c'mon.
You are absolutely right
The media ALWAYS reported on incidents like these before the internet. The only thing now is that we know an hour after it happened instead of at 6pm when the news came on the TV.
Oh, and we've almost always got 4K video of the takeoff and landing now thanks to the abundance of cheap cameras available.
Billions of people walking around with video cameras in their pockets able to stream instantly to the rest of the planet. It wasn't always like this. So naturally we see more of everything today than we used to, but it doesn't necessarily mean that _____ is happening more often.
WTF is going on with United Airlines lately. They really need to investigate their maintenance people.
Maybe they should have taken the money they spent buying back their stock to artificially inflate the value, and instead invested it in more maintenance employees and more training programs.
Nothing to see here. Nothing is on fire. When Boeing sold its manufacturing to a venture capitalist there was also nothing to see and there were no dumpster fires later.
Many airlines are off shoring the maintenance to cheap countries
it's getting too dangerous to fly united
It's that bloody dei training and their inclusive hires program. Darn yanks
I think United needs to investigate their maintenance departments. IMO
Great to have a place where all the aviation experts can meet.
Yes, as others have noted, it was an hydraulic leak issue. Look at 1:08, the landing. Main Gear doors still open....this means that the hydraulic system that operates the gear and doors has failed. This is NOT a maintenance issue. It is simple mechanical failure. We train for these contingencies.
You cannot know yet if the hydraulic failure is or is not a maintenance issue.
Bravo. FINALLY a commonsense, accurate answer amongst the Boeing/United bashers. Well said sir.
When gear doors stay down, you bet your boots its a hydraulic failure in the system.
Isn't maintenance supposed to prevent mechanical failures?
@@AnotherDougDo you maintain every component on your vehicle? Or does a belt let go or a rad hose fail.....Maintenance reduces issues. It does eliminate them all.
Absolutely a beautiful, by the book, emergency landing. Perfect!!! Well done flight deck crew!! 😊
Maybe Juan Brown?
@@emilkarpo Sorry you lost me there.
Was Juan Brown in that team ? He is the " blancolirio channel ". He will let us know, when he has a minute. He flies a 777 but I do not know if it is United or AAL He lives around SF and goes to Australia on regular trips.
Could be Juan, he flies out of SFO
@@emilkarpothat would be quite the coincidence but I guess it's possible.
United has 949 aircraft. 944 of them made their flights without issue.
And most of the 944 yesterday flew multiple flights!!
@@brandonbrown4819 Quite correct.
Wow thank god everybody came out ok.🙏
10 years ago my family and I were on a United flight from Rafael Hernandez International Airport in Puerto Rico to Phoenix Via Newark with a 2 hour layover and the departure was late due to plane problems causing us to miss our connecting flight. Well we slept on the floor at the Newark airport where stuck for 19 hours and it sucked bad. No reimbursement, no motel and not even a invitation into the lounge. NEVER AGIN!
My family was trapped in similar circumstances, they just kept saying it would be two more hours over and over until 16 hours had passed. We would have checked ourselves into a hotel if we had know how long we would be there.
Aircraft go tech all the time. Whether you get a hotel or not depends on availability.
Too much focus on saving money and not on customer service these days
During the peak of Covid , lots of airlines were out of action and stood idle for a long time maybe this is the reason lots of faults are showing up recently
Huh? That was years ago. More likely due to United's DEI programs. Plus, isn't United's CEO a drag queen?
How long ago was that???
@@edwardrichardson5567 Less than 6 years...
No, that was 3 years ago.
@@linanicolia1363So…. Less than 6 years like the prior answer said then
The tires didn't get the memo that this was a non-smoking flight.
That was just lame....worse than a Dad joke

United seems to be having some wheel issues within a week - last week a wheel of a 777 fell off just after take-off an damagin a car.
That was Boeing plane and it landed in LAX
There is nothing wrong with Boeing, it's United Airlines maintenance which is not up to date. Wheel falling off last week and now....United Airlune has never been reliable since 2015. Next year will be 10 years.
@janblackman6204 Has nothing to do with it being a Boeing. That was purely a United maintenence issue as the aircraft is over 20 years old.
Yes, some wheely public wheel issues
And the following day a United 737 slid off the runway at IAH in Houston
What is going on with united plane’s to many problems with the landing gear ⚙️
I'm surprised Channel 7 and Channel 9 didn't put this video on their 6pm bulletin. Isn't TH-cam where they get all their news?

Fantastic capture! May I feature these scenes in one of my next episodes? Of course with a link back to your original video. All the best to you :)
Yes, of course. Thanks for asking!
@@NewYorkAviation- And thank you for being so understanding. 🙂 We all appreciate your generosity in making your video footage available for general viewing.
3 Minutes of Aviation provides a really useful round-up service on TH-cam (the channel has a huge following of both experienced professional pilots and 'ordinary' aviation enthusiasts), and has become the first choice for those of us interested in flying matters but without necessarily having the time to watch a 4-hour live-stream.
The comment sections of channels like yours (and 3 Mins') are always worth reading in detail; plenty of informed discussion by people who know what they're talking about.
[I don't include myself in that category...🤭]
Props to 3Minutes for asking to use and properly credit the footage, and props to NYA for being happy to have it shared.
And funny thing is all these planes are based out of SFO a major united hub and maintenance center. So what gives.
What a great catch! Would you be okay with me featuring parts of this in my series Weekly Dose of Aviation? Of course you will be credited both in the video and in the description. Thanks!
Other airlines operate these same aircraft without the problems United is encountering.
Maybe they operate it less often or have a shorter service life so far. Possible? One needs the details before making conclusions.
I wasn’t drawing any conclusions, just making a true statement given the facts in hand.
Not True. I dont know if you noticed, but these big behemoths are basically machines and they do break. The focus here should be and is the actions of the crew. That was perfect.
Maybe they are flying them by AI
I agree that the flight crew performance was exemplary, with the possible exception of the plane that went off the runway/taxiway at IAH. I hope United will examine these issues thoroughly, in conjunction with the FAA and airport maintenance.
There have been several emergency landings of Airbus planes in the last couple of years, for hydraulic failure or smoke in the cabin, but they don't usually make the news.
Because airbus usually doesn’t kill anyone
Some one or some group of journalists have a bone to pick with Boeing.
@@SKYSTAR767 well being in the news all the time with issues kind of puts the magnifying glass on them and rightfully so

Questionable maintenance at United these days it seems...
What makes you say questionable? What are you talking about?
@@157294 This story follows another last week when a wheel fell off a B772..... questionable maintenance as I said.
I hope we don't go blaming Boeing for this. United has been having all kinds of issues. Just last week a tire fell off a triple 7. It was diverted to LAX with no issues. I think that United needs to hold the mechanic accountable. I feel these are mechanical issues. I watch some of the videos from JP Pilot and let me tell you, some of the tires on those planes should not be on there, but they think they are good. Pilots also need to be accountable. If you have to wait to resolve the issue, so be it. We have all been lucky, but one day we might not be so.
Cierto, nunca he sabido q le den cadena perpetua o pena capital, a mecánicos irresponsables, a controladores aéreos o a supervisores
This is the 2nd one The other one was at LAX landing gear problems a few days ago ???
Correct! Was going to mention that. Thank you
Don’t forget about the one in sfo losing a tire on takeoff.
United has 949 aircraft. 944 of them made their flights without issue.
and the United 737 that slid off the runway at IAH
Ahhh they ran off the runway in Texas and there have been 5 or 6 in the past week😂😂😂. May I suggest FAA check Maintenance records or start keeping a flow chart. EXECUTIVES LOVE FLOW CHARTS😂😂😂😂😂😂
great capture and footage Sam, not your normal upload but every entertaining :)
So this would make incident number 6 over the course of a week involving United Airlines?! They've got some serious issues to work out.
@@Aesopsfabledoo Oh really, explain.
@@UPRailRoad-xg8cbthis would be number 5, and number 3 for maintainence causes.
1. Engine fire was caused by airport failing to clean up bubble wrap
2. Wheel loss caused by maintainence
3. Runway excursion caused by ATC ordering pilots to not slow down, causing an oversped turn
4. Maintainence, but this time it’s an Airbus
5. This, caused by maintainence, the 777 has a great track record in a sense that no previous incident involving 777 was caused by Boeing.
@@Blank00 Don't forget the 4th maintenance story. A United Airbus A320 departing O'hare for Salt Lake City had to return to O'hare because the oil light came on. Still, 4 incidents involving United Airlines maintenance over the course of a week does nothing to boost my confidence in the airline. I still say they have some serious issues because that number is just too high.
@@Aesopsfabledoo they aren’t.
@@UPRailRoad-xg8cb I already mentioned the A320 incident

Turn mic off when in the wind!!!!
@user-uq2rr4xt9g. Turn comments off when nothing useful to say.
Clearly see that tire smoking and on fire at takeoff. YOU would think they would get an indication for their sensors in the wheel bay. Luckily they got back.
Nice coverage 👍
Seems like a group of people are set on shorting United stock. These problems occur all the time, but are rarely reported on the news.
I was thinking the same thing!
Love all the expert comments 😂
Well done to the crew for getting the plane and passengers back on the ground safely.

What happening with United airlines Maintenance????
th-cam.com/video/q4Dd50d45Bc/w-d-xo.htmlsi=tRZYbRSGo2F2fnBw
What has gone on United in last week or so is nothing unusual, about the same amount of trouble goes on at all large airlines. As of late the news and social media have been reporting anything and everything their get their hands on.
They got "upgraded" by Boeing QA.
Reminds me of when I lost a power steering hose on my 1970 Nova. What a mess.
Serious concerns for United. I would think their CEO is in contact with the head of maintenance to get a grip of what's going on.
You mean the CEO that’s busy dressing up in drag and parading around at parties?
Nah...he is more worried about DEI.
Sad but true.😡@@nationalzero269
The CEO of United made a powerful speech , a couple of days ago . He is taking the blame for everything. What a nice guy !
They've lost anybody with any sense so they're stuck and this will be the death of this airline
ANOTHER United jet? Is this a statement of United's mechanical upkeep? I've long known United was growing faster than its system could handle (my opinion) and we're now seeing the push to turn the aircraft quickly might be causing the maintenance to lag behind. Remember, there are REQUIRED inspections to be made at intervals as prescribed by the plane manufacturer. They are known as A, B, C, and D level inspections and different steps are taken for each. Obviously, the wheel hub is again affected on this aircraft (as was the aircraft that lost a wheel taking off from SFO). This IS NOT a Boeing issue! It's a maintenance issue!
It's a material issue. The vendor who overhauls the wheel/tire assembly, might have missed a crack on the wheel which failed. It may have been extremely hard to detect. Not so much a United thing.
This was an ETOPS operation. Everything is checked twice and by two different techs - then each tech has to sign off. Still they are machines and, as we know, they break from time to time.
Like the pilots that "broke" the 737 in IAH ??
@@Steve757-fl1hd
Maybe you should wait for all information before making assumptions that - possibly - makes an ASS out of you and me. ASSUME. Get it
@@richardcranium6878 oh, how witty! But not original. As the plane was sitting on the taxiway, you could see the smoke coming from the wheel hub area, so not much in the assumption necessary for that opinion. Not sure how much aviation knowledge you have but I have been studying the aviation industry for decades now.
Damn my family and I are traveling internationally next Month and we are riding United, all this United issues that i have seen this week is making me feel unease.
not an injury so far. Go for it and have a nice trip.
You will be just fine and you’ll have a great experience. It was the actions of the well trained crew and they did great.
The only thing that scares me about flying, is the *drive* to the airport. 😕
Whenever I fly, I deliberately avoid aviation videos and news for a month before I go.
This is why I fly British Airways! Rubbish customer service but safety first!
All of these United Airlines incidents. My roommate just started a new job as a flight attendant 2 months ago. She was on the plane in Houston that skid off the runway a week ago.
Looks like a loose or ruptured hydraulic line leaking on to the wheel brakes they get extremely hot & radiate heat for well over an hour after landing or even taxing before taking off.
Wear and tear, stuff happens, that's why there are so many tires and brake disks.
Let’s blame someone before we know the facts.
Yeah, just throw someone under the bus and look for a scapegoat. I saw this mentality in Manufacturing for 30 years.
The gear doors are not withing my knowledge but the smoke coming from the wheels is one of two things, a dragging brake system, or a failed wheel bearing issue, but both create massive amounts of friction that cause the brake pads/shoes to heat and burn up inside of the assembly as well as any rubber inside as well, and can eventually cause the tire to start burning as well, and eventually fail/burst, which, if you are aware of the pressures inside of aircraft tire, can be a catastrophic event. and those firemen are taking a serious risk standing that close to a smoking tire. Since we cannot see the inside bead of the tire and its condition up against the rim.
The gear doors not closing means the gear has been extended using the a,ternate system (gravity). This points to a hydraulic loss in the centre system. That spray seen on departure is the centre system emptying itself.
To be honest it looks like a failure of the hydraulic pressure line to the main truck steering actuator which is positioned at the rear of the trucks and actuates the rear two wheels for tight turns (will give a takeoff config warning if TO power applied and the bogeys aren’t lined up fully)
I used to be an airport firefighter. The risk is aligned with the axles, so they are following the correct procedure. Notice they signal the airline person not to walk close past it. They are also using an infrared camera to look for where the heat is and how much. It’s not at a level you would normally associate with a wheel fire or failure. Aircraft firefighting can be fast and massive, but there are also times for a measured response. You can be certain the four tenders are ready for immediate massive firefighting if needed. Most of this is happening after passengers are off, which will have been their main priority.
Great catch!! It was definitely smoking at time they lifted off.
Thanks! Right place at the right time, my first time spotting at SYD too. Only caught the smoke on takeoff after editing!
@@NewYorkAviationYou could probably sell your camera work to some of the US Main Street Media. They'd eat it up!!
Smoke does not always means fire. It could be evaporation of hydraulic fluid on some hot metal.
so bottomline..what was prob cause of r wheel gear smoking ? burning ?
what ?
I’m no longer flying United that’s for sure. I live in Reno, close to San Francisco which is a United hub. But seeing all these events unfold all week, I’m ok with Spirit 👍
What are you afraid of?
We all love the banana
If I was an employee of United, you can bet your butt I'd be out looking for another job with another carrier. Jeez, think of the cabin crew had to go this mental torture cause they fly so regularly for a living. I know of one stewardess (From TH-cam) who is American went to work for Qantas and her Husband is Australian and I think - but don't quote me on this, previously she worked for United or American Airlines, I would love her take on this
Reno is NOT any airlines "Hub"....... Haha - wishful thinking
I expect a complete report from Juan Brown. Thought I saw his smile in the right cockpit window.
Only trouble is Juan works for American.
Clearly, it was a manual gear extension, that's why the gear doors are still open. Just looked it up and they stated it was a hydraulic leak. That would explain the gear smoking. Sometimes the anti-skid systems (or the aircraft's ABS brakes) will fail and the brakes will lock when the aircraft has low hydraulic pressure, and that's the reason for the brakes smoking. But with so many issues, back to back, if I were United I would be auditing my MX facilities big time. MX failures happen and are normal, but this many this close together is ridiculous.
Looks like the main gear steering hydraulic line ruptured. The brake systems have fuses, which close if a brake line fails. The smoke is most likely from Skydrol (aircraft hydraulic fluid) leaking on to the hot brake. Skydrol is fire resistant, just smokes ALOT when heated.
Too many incidents in too little time. I'm starting to wonder if it could be sabotage. 🤔
Spot on explanation and excellent systems and procedural knowledge. Ground Instructor? Check airman?
Brakes work off the right hydraulic system.
@@EdOeunaOkay. I know on one of my aircraft that if you lose systems or one system has low pressure, even if its not the one that is hit, you will still lose anti-skid. You won't lose breaks just the anti-skid protection.
You can see a growing puddle underneath the right main bogie, rear right wheel. I'm guessing the aircraft was leaking from a brake cylinder or hydraulic hose.
We may have a Blancolirio update where he was part of the crew.
He flies for AA.
United @@JBN137
We’ll get an update fromJuan regardless guys!
That would be ironic and definitely interesting, if a AA 777 had an emergency, with Juan being the pilot.
There is a story going around that a senior NTSB investigator had an emergency, something like partial, then complete loss of power, and made a successful dead stick landing on a divert airfield.
I can only imagine having their friends write the NTSB report if the airframe had been damaged. Not sure on the details of who was involved or when.
He works for United @@neuropilot7310
How many incidents does that make for United in the last 3 months?
Too (as in too many incidents, not two incidents).
OK, can someone please tell me what the hell is going on with aviation? After 100 years of commercial passenger flying, why has the human race suddenly forgotten how to fly? What the hell is going on at United? 2 777s in two days....? THIS IS NOT NORMAL.
swanvictor Look at flightradar of a shot world wide and see how many planes are in the air at all times, tens of thousands, and stuff does break or wears out or get missed, Only surprising thing is there are not more problems showing up, also he age of aircraft....
Aviation is absolutely the safest that it’s ever been in all of recorded history. 50 years ago, it was common for several aircraft to have full hull loss incidents.
Aviation in the 70s and 80s was astronomically more dangerous than today.
10,000 safe flights a day and as you can see this plane landed safe
well, my mind has been put at ease by all these reassuring comments about how safe the industry is and seemingly, so many people are more than sanguine with the multiple reported failures from Western Airlines over the last few weeks: good to know I'm concerned for nothing and should be more relaxed after all, nothing bad ever comes from complacency, does it....?!
great great awesome pics zoom full vid of this landung.. awesome great catch ! never would have seen this at all rly ever
united airlines have a serius problem for the maintenance
i was in an United airplane in 2010. It was a flight from Orlando- Oslo,Norway. Full stop at take off. i think we had about 80 knots,when the plane have full brakes,, i was so scared,overheard that it could be a hydraulic failure. i really don’t know what happened,but for sure,it was scary.
Maybe the tyre wanted to depart!
LOL!
😂😂😂
Like the one in LA few days back
Wow! There was no doubt that you saw what happened the aircraft. I did see smoking coming from tires, but I don’t see any evidence. I’m sure they will fix it soon enough. That won’t happen again until the entire aircraft is fixed.
Problems at united again . Wow 😮
Definitely hydraulics. Unless there's some other damage, they'll clean it up, replace a hose, refill the reservoir, purge the system, and it'll be in the air later the same day.
This could happen to any airline & any plane, anything mechanical is at risk of going wrong. I feel for United though as they`ve been very unlucky recently lets hope this luck changes for the better quickly.
Time for the FAA to cancel 1/4 of all US Departures until United get these numerous maintenance issues corrected.!
Can someone tell me what the firefighters were doing? By the looks of it not much apart from creating a puddle around one of their trucks!
Standard procedure. When airplane issues mayday they must be there when the plane lands
They have the ability to remotely read the temperature of breaks, and given that they are still smoking, may take action.
I think they are also seeing if the wheel heat can disperse without any water, which may cause other issues.
Hydraulic fluid is quite flammable and brakes can reach temperatures over 1100 degrees C after landing; not a great combination. The crash crews are there as a precaution.
I take it you didn't either watch this from the beginning or note the smoke trail, as the landing gears were about to retract
@@stephenrickwood909The hydraulic fluid is not flammable. The brakes do not get that hot, maybe 600c. If they got 1100c, the tire fuses would blow.
6:00 why aren't the fire trucks spraying the smoking tire?
If it's Boeing, I aint going.
If it's airbus then I ain't gonna bust
@@SpottinPlanesForLife doesn't have the same jingle, lol
BOEING company has been always been plagued with safety and quality issues. Poor Organization. Poor Management. Poor Safety Standards. Poor Design and Engineering Standards. Poor Material Engineering. Poor Customer Satisfaction.
The Loss of pressure may well have been noted at take off and the 2 Hours in the air may well have been to burn off fuel, conduct test procedures and prepare to land. Its unfortunate to have happened but it seems it was handled well. It also extremely likely that the flight Control System hydraulics are fully isolated from the Landing gear systems. Most here are speculating (including myself) as to the situation plenty of armchair experts and inexperts among us indispersed with good reasoning and explanations.
I doubt maintenance would ask the crew to trouble shoot. Identify the problem, run the procedure to secure the system and burn off fuel to MLW. Deadheading crew gets to crank the gear down (99 cranks?). Oh the memories!
United Maintenance is horrible right now. We had 3 planes with mechanical issues back in December 2023. We waited almost a day to leave the airport. They need to get it together, with all these issues lately. Either their maintenance crews are not qualified or they are knowingly cutting corners. As a United club member, this is unacceptable.
This is the last thing Boeing needs at this time ! Issue on the production line or bad luck ?
Maybe both?
Agreed, a bit of both. This 773 has been in United’s hands for quite some time… a lot of the blame is on them.
@NewYorkAviation Ahh yes. Blame. Sir, the day one of these falls out of the sky and splatters itself over land or ocean at 500knots.
Rest assured, I will be looking for someone to blame.
But right now, it's a question of responsibility, duty of care, proper manufacture and maintenance.
No one needs to be blamed.
No one needs assurances.
What we the public need, is to know that Companies are doing their jobs. Not just paying lip-service to quality control and safety, so executives can get a bigger bonus.
I can't speak for United Airlines, I've never flown with them.
But Boeing?
The day we can't trust them to build the Best airliners in the World?
Will be a dreadful day. 🇭🇲
@@downunderrobNicely said, sir.
Not a good week for United.
What did maintanence do the the gear that's not been done before now?
Nothing, the problem is more likely they failed to do something.
Maybe its CEO can stop doing drag shows, come down off his Woke cloud, and pay attention to running his airline. Is aircraft maintenance personnel now hired and promoted by DEI standards?
Shut up -everyone
That was hydraulic fluid. They flew for two hours to dump fuel. The gear doors down after landing indicates hydraulic failure and the gear was gravity lowered.
UAL is big on DEI... Maybe they should drop the woke and hire qualified people.
Great footage but how did you get it? Are you actually allowed to fly a drone inside the airport?
Not a drone. There are regular plane spotters taking videos at a few locations around SYD
Footage most likely shot from the P6 International car park.
Maybe United should wake up and smell the coffee and stop ordering aircraft from Boeing. Quality and safety is not a Boeing priority, only shareholder profits and executive bonus checks.
thailandrose hey dummy, its a maintainance problem !!! Machines need servicing regulary and pars wear out need replacing.... or are you not aware of that !!!
In the background, is that the same LATAM plane involved in the drop incident???
Ahhhhh I see DEI hiring has struck once more.
I think maybe you need some mental health help mate...
@@swanvictor887 look there. U must be a whiny democrat who absolutely believes in DEI
Another racist commenter
@@swanvictor887na DEI is an issue

You can clearly see the "Heat haze" or heat shimmer from that engine causing the tire to almost ignite and smoke.

So glad it landed safely. That had to be scary. Great job by the pilots and crew.
What's the circle indicating? The smoke or one of the wheel sets didn't retract?
You highlighted the wrong tire, dude.
In September 2023 I flew from LAX to HNL and on approach at HNL we made a go arround and the captain made an announcement that there was a problem with the flaps
Passenger planes need cameras installed in vital areas. There has been instances when engine smoke & or fire occurs & the passengers observe however the pilots are oblivious to. I thought the landing gear doors had a sensor switch and indicator light that allows the pilot to know that they are closed.
Of course the crew would have been notified that one of their hydraulics systems lost pressure. There are many sensors on passenger planes - they don't need to be cameras. That's why they returned to the airport they had left an hour earlier. From other comments, the landing gear was lowered without hydraulics and the doors were necessarily left open because of insufficient hydraulic pressure to close them.
Is that 4 incidents in a week???
Seven for UAL in eight days
The red circle 0:33 is in the wrong place, it should be on the right gear, inboard aft wheel/brake. What is that on a 777, 3 rear? Oil, maybe causing a little smoke if oil sprayed onto the brake, which will be hot after taxing. Could be from a brake line, pressurised at retraction (about 350 psi?) for despin during retraction.
