"MAYDAY, MAYDAY, MAYDAY" UAL 328 B-777 200 20FEB 2021

Boeing cutting costs again with shitty cheao P&W Engines

When and why would a pilot use a "Sideslip "? And can it be done in a Bad weather storm ?

Juan, do you ever attempt to talk to the pilots after some point in time?

Soccer mom keeps kids outside under the debris field. Juan, yeah It'd be a good idea to get outta there. LOL

Great commentary Juan, as always. I've gone to the 787 now, but the Triple will always hold a special place in my heart. Kudos to this crew.

Thanks for your channel, probably better than the aviation week report to come out next month.

Awesome video! Thank you Juan for always providing great information and explanations in your videos!

M’aider m’aider m’aider

Not good job United, Good job Boeing...United was responsible for maintenance on that engine. At least that is my thoughts!

Great analysis of a catastrophic engine failure and hats off to all the personnel who demonstrated very competent and steady nerves as they brought this serious incident to a safe ending without any casualties or significant injuries.

10:35 "The single-engine departure procedure for runway 25 has you turn to the left. So that's good. You're not turning into the dead engine. You're turning away from the dead engine." Naively, I would have thought that turning into the dead engine would have been easier (given the asymmetric thrust) and thus safer, and that for a given airspeed, the engine on the inside of a turn would have been exposed to slightly less wind, perhaps preventing additional pieces from being torn off. What is the rationale for the advantage of turning away? Is it, perhaps, that the engine on the inside of a turn is exposed to more turbulent air?

Interesting. I _did_ see the passenger's video footage last week, but I was unaware that it had just happened. I hadn't heard the radio traffic until now, so thanks for that.

Good informative video with expert aviator! Greetings from snow covered Finland :)

JB good reporting on UAL 328. Have you got any info on the AAL 2292 Capt. Reporting a UFO to ATC while at cruise alt over NM? Something like 'long cylindrical object just went over us really fast'. AAL admits it was their radio tx but says talk to FBI for further info. So might be tough to get info but hope you're working on it.

Question: are passengers moved away from seats inline with an unstable engine? Parts may dislodge and enter the cabin.

I wanna know how they get all the other aircrafts organized when a mayday plane is inbound.

Thanks. I love it when ATC says the airport is all yours, any runway, stop where you like. All good, but 27 years old, ain't that old for this type of aircraft?

big thanks to you for the report and VAS for the audio. crew and ATC all professionals and met the moment.

Always mix at 50 to 1 to avoid seizures like this.

It's hard to trust mere humans with maintaining engines like that, let alone designing them. But what else can we do?

The crew did an absolutely perfect execution of engine out procedure at take off. One passenger that was on board has video on Tiktok of the engine starting to come apart before rotation! The engine is loosing pieces and you can still see runway under the aircraft! Pilot was probably pulling up the gear at that moment because a few seconds later you can see the end of the runway. If the pilot would have tried to abort the take off it would have been a disaster. Engine couldn't have failed at a more critical time. Crew handled the situation perfectly.

And this is why you want to fly on an aircraft crewed by pilots that are trained to western standards.

Wouldn't they have had to dump some fuel to?

Transcription error all over the internet on this. I award points to Denver Departure. When the Mayday was announced, he did not reply "Somebody stepped on you". He said "say again, can you read that again?" That's what my old USAF ears hear.

Can you do a video on how ATC handles the NON emergency aircraft around the airport in a situation like this?

Well trained pilots easily dealt with the emergency. Not so with the 737 Max crashes ... where poorly trained pilots did not know how to properly deal with a runaway trim emergency on a 737 shortly after take off. And yet Boeing got the blame for two poorly trained aircrew. The dealt flight crew from the 737 Max crashes ... would have also crashed a 737 Jurassic, Classic, or NG suffering a runaway trim emergency in a 737 ... shortly after take off. The 737 Max should have never been grounded. Boeing didn't make the flight sensors nor does Boeing do airline maintenance or pilot training. The was nothing wrong with the MCAS system. Not fool proof but nothing wrong with it. It did it's job. The 737 Max only needed a MCAS software upgrade to make it FOOL PROOF. All Airlines flying the 737 need to ensure their pilots are properly trained.

Great coverage Juan, great response from the crew & ATC.

SO, DOES TEXAS USE THESE FEDERAL EMERGENCY STANDARD PROSEDURES, OR IS THAT CONSDERED THE FEDS GETTING INTO TEXAS STANDARDS?

Perfect example of an engine failure on rotation having no apparent effect on the climb away from the runway at Manchester Airport UK for any who are concerned about flying on twin engined aircraft. A TUI B757 Nº 2 engine bird ingested on rotation, see uzones.info/plus/video/aXzOi6qpjqh_en4.html

Great job! Very informative documentary !! Praise God that all are ok !!

The homeless chin thoracically jog because squirrel fourthly rinse into a imported quartz. makeshift, obnoxious knot

Not understanding why procedure calls for turning AWAY from dead engine. The remaining left engine would naturally yaw the aircraft to the right, why not utilize that force?

good job United !!!.....

So grateful we have so many great professionals flying these aircrafts today. Cool under pressure.

Great job! Most fortunate there were no casualties on the ground. The last I remember such an event occurring was the Quantas A380 out of Singapore with Rolls Royce engines, suffering an uncontained engine failure with nasty damage to the aircraft structure and debris falling on a school in Indonesia.

Haven't seen you in awhile. Nice job and glad to see your back flying.

It was a gremlin. LOL

Thank You... Just Thank You! So much anxiety is now gone for me.

THE DEFECT ENGIN SHOULD NOT STILL BE ON FIRE AFTER THE PILOT ENGAGED THE EXTINGUISHER WITCH MEAN FUEL WAS STILL COMMING IN THE ENGIN AND COULD'V LED TO WING EXPLOSION SO BIG FAULT HERE

Good thing it happened early then over the pacific en route to hawaii. Hope nobody got hurt by the debris

Thank you for going over this. I work close to where all this happened. We were so relieved there were no injuries in the air or on the ground. Great job United.

Use an Airbag underneath your jets son...save hundreds of lives. no you really can do that.

I bet when the oxygen mask dropped down from the ceiling a new pair of underwear dropped down with it.

Absolutely training paid off. Shows you the professionalism of these guys working together. Very lucky indeed, this could have been so much worse especially with full fuel load...Thx as always for your great reviews.

7:15 can't see anything. You do know you can put videos at fullscreen, right?

Requesting MAYDAY

Thank you.

We have it on good authority that the incident happened "thousands of miles in the air". Watch at the 1:00 mark in this news report... uzones.info/plus/video/ZKXFp4OnnHyZgY4.html Reporter confused or actually ignorant?

Thanks for the Video. I'm glad you mentioned the immediate need to make a turn away from the rocky mountains, most of the reports missed this.

Kudos to the crew and to the ATC. Beautiful job and lessons learned. New video identifies fan blade failure as the root cause, I had not thought about landing the parallel runway due to possible FOD on the departure runway.

In WWII that would be counted as a "probable". Very glad no one was injured, very sorry the failure occurred. Determining the cause and whether any failure was due to offshore manufacturing (if any) will be interesting.

What you don't see is the effort behind the scenes by ATC to clear all other aircraft out of the way in order to give this aircraft the priority it deserves - it's quite a bit more complicated than you might think. I've been in that situation, I know

If you look one of the other videos from a passenger further forward, it must have been done with a newer iPhone, the FPS and image quality are high enough to stop or pause the video and see the two missing blades, the root separated blade and the trailing blade broken mid-span, jus like the other two failures, December 2020 and the 2018 HNL flight.

Thank you for the informative report as always. Most of the passengers aboard were probably not aware of the seriousness of this engine failure. The crew did a superb job ; as you said that's why they get the big bucks ! Glad no one on the ground got hurt either; pretty big pieces fell in that yard.

Fan Blade ... metal fatigue. Not the first time this has happened. Put Greg Feith on the case.

Why get it from you? We too can do our own news search.

So if you are the Denver Broncos football team the first officer becomes the quarterback , runs the offense . The captain becomes the offensive coordinator , decides the best plays to run to score. Touch down United ! 😊

Boeing planes are not what they used to be.

So! Question here - Why are these engines failing - Back in the day when rolls royce engines were used on the 747 never had these problem fan blade failures...Something tells me that the engineer's have to go back and redesign these blades. I kinda get the feeling that either bad maintenance when a inspection is performed or bad parts that are still in the system where some one is passing these so called semi passable parts with out doing a full integral check of the blade in question meaning there could be dosen of flawed blade that are waiting to fail like this one did. The tv show 20/20 has done investigative reports on shoty practices of used parts being put back into service that have questionable paper work -???

Ironically.... the tail number 772 is the same tail number as Southwest flight 1380 aircraft that has similar emergency. (N772sw) (N772UA)

***** _THANK YOU, JUAN-!_ Hopefully, not a silly question -- but why didn't they activate the *FIRE SUPPRESSION* on the starboard engine ..? SIDE NOTE: Thank you for your viddies. I discovered you on the Oroville Spillway catastrophe and please know, amigo -- what you do matters to aviation and the wellness of your fellow humanity. D.A.

Great analysis as always Juan. Just wondering if you could comment on the difference between a heavy mayday and a regular one? I'll let myself out now! 😅

Capitan Behnam has saved another crash in 2018 , check him out , he must be an angel 😇

The MSM was no doubt salivating but everything turned out fine. :-) :-(

"Good job, United."

The calmness of the aircrew reminds me so much of radio traffic for Captain Sully when he landed in the Hudson River...very professional...well done!

Juan, is this the same engine series that lost an engine out of philadelphia last year.

Pilots were absolutely awesome but also, ATC!!!

What are the odds of two identical engine's fail exactly the same way in 24 hours of each other ???

It’s really great to have you explain in thoroughly understandable terms what and why this happened and all the associated procedures that were put into place during this emergency and from an experienced pilot of yourself, well done and thankyou, but it also shows what may have happened if the engine fan blade(s) and nacelle/cowling parts happened to explode apart on a different trajectory and damaged wing slats or fuselage, severed hydraulic/fuel lines etc which hypothetically could have happened also but the fact that it looks like it fell away from the aircraft structure and landed without any injuries is a good thing but looks like it easily could have gone the other way, you have a great channel, extremely interesting thank you, cheers from Melbourne, Australia.

I've always said commercial pilots are the best trained professionals of any profession in existence. Great job by the crew, that could have went really bad like American 191 heavy.

I was thinking about you and your channel when this happened the other day. More so since you fly a B777 and wanted your thoughts. Thanks for sharing

It's great that people have so much video of these engine failures. It could be helpful in determining what happened to cause such a catastrophic event

Do the 777 engines use jet fuel to hydraulically operate variable stator/guide vanes or bleed valves? If not, what do they use? Wondering if that could be the source of the fire

Excellent presentation, as always, Juan. At about the 19 minute mark, you talked about taking the ILS in order to stabilize the approach and minimize the chance of a go-around This is key. As a pilot , you know how to land the aircraft. Do it. Make it as normal as possible Figure out what she will do, then take her to the runway (or field, if necessary) Don't be the guy who rolls his helicopter over because he's worried that he forgot to check the fuel cap.

impressed by the professionalism of all involved.

why dont aircrew notify the flightcrew of souls on board as soon as the a/c is buttoned up?

I don't watch Major Fake News Networks anymore - I go to the expert channels to get the real news - channels like yours.

Thank you!!

it was contained no debris from the engine penetrated the aircraft it was all contained within the engine.

Wow! Never heard a report this clearly ingormative. Very exciting too.

1;51 a turban is what a seikh wears on his head a TURBINE is what is in a jet engine learn to pronounce or enunciate or learn the difference do not call yourself or try to portray yourself as a so called expert if you cannot describe the relevant parts of an engine by their correct names. I watched a video earlier with ATC tapes provided by VAS Aviation (thanks Victor) and that presenter knew the difference between a turbine and a turban

What if this engine would have exploded midway over the pacific? With that engine shaking on fire would they have needed to ditch it in the water. If so that's very scary thought.If it did go down in the pacific would it have been survivable. Floating rafts and life vest?

A lot of comments are, " why didn't they just get on the ground ASAP but they were taking their time and doing checklists etc. I was thinking this plane is full of fuel and probably loaded to the max. an plane like this has a max takeoff weight and a max landing weight which is considerably less than the takeoff weight. That's why they have to dump fuel before landing . Nothing was mentioned about dumping fuel. Was it because dumping fuel would be very dangerous since an engine was on fire?

Thankfully this happened over land and not far out over the water.

i just scrolled your video ........ you must be an investigator or a pilot on the same plane ....... im not happy how people want to abuse a drama that can kill

Fantastic and insightful as ever, Sir: many thanks. Wonderful that no one hurt in the air or on the ground. What strange times for aviation! Thanks again...

When I was a kid I think it was in the late fifties in the San Fernando Valley an engine fell off a jet and landed in a school yard. The whole area came out to look at it. I don't recall about the rest of the jet. But it was shocking even back then. Just looked it up and yes a mid air collision.

I hate that Denver airport. Very good job.

I wonder how heavy were those parts. Would potentially deadly for any on the ground?

Hey Blanco, you keep an eye on them gauges next time out. No looking out the window and telling jokes. Those P&W's can blow anytime!

That fan blades around somewhere, its bound to be found by someone

excellent analysis

? Fuel load ?

nice and excellent information tks

Thanks Juan. Good report as always. As an aside, I had 5 engine failures in my 41 year career but only 1 was catastrophic - most of those happened before cell phones and the internet had been invented. So the bigger question - Did they get another plane for the trip to HNL before their duty time ran out? :-)

So here is the question.. had this failure occurred over the Pacific, halfway to Hawaii, could the vibration from the engine have caused the engine to fully separate from the wing, causing the plane to come down?

Great video

Ok, this engine shouldn't have failed, but accepting that this might happen, being prepared and designing for survival is remarkable. Well done to the designers and pilots for making this a survivable incident.

They had a turbulence alert for 14K to 22K feet when they took off. The engine blew at 13K feet, so is there any chance that rotor winds from mountain effect turbulence pushed too much air into the engine and caused a compressor stall, which might have triggered the turbine disc failure(s)? That was my first thought.
