  • 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.

  • 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.

    Mark GallagherMark GallagherNgày trước
  • 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.

  • 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 -???

  • 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.

  • 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.

  • 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?

    TAN GRETAN GRENgày trước
  • 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?

  • 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.

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? :-)

    Ron HuntRon HuntNgày trước
  • 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?

    Roger FroudRoger FroudNgày trước
  • 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.

Well, seniority concerns/quality of life AND the destination/trip mix just never appealed to me at that time.

  • It seems obvious that if "uncontained" that the failure occurred in the turbine. As the bypass and compressor fans seem intact. A "contained" failure would mean a catastrophic combustion chamber explosion. This seems unlikely. It is far more likely that the failure was in the turbine. So, we will see; what the NTSB investigators have to say.

  • Wow that gets the old blood flowing. Thank God nobody was hurt. When it happened I was told that it was right after TO. Wrong, amazing seeing those pieces fall. Somebodyfs guardian angels were working overtime. Great job all around, now it's going to get interesting. What in the world caused that kind of damage? Maintenance crew, stress fracture, FOD, gremlins, crazy looking creature out on the wing and nobody believing the future Capt. Kirk? Sabotage probably isn't a factor but God only knows what folks are thinking today. Thanks Juan.

  • Picture on Reddit and Imgur showing damage to central fuselage imgur.com/6lZBMYj I believe this is where 26000 gallons of fuel would have been on a transatlantic flight. Would that huge slash hole been caused by the compressor shaft? Would that have downed the aircraft. More pictures are being revealed from the starboard side now.

  • As somebody else mentioned, I was told this by a friend with whom I was walking my dog yesterday. I had seen odd news images of the front ring and honeycomb panels, but I hadn't known until she told me, that the engine "was still on fire" which I found strange. My immediate thought, like many others, was; I'll wait until Juan comes up with a preliminary! That video of the engine in flight is both disturbing, yet fascinating. As an engineer (not aeronautical) the overall, immediate, reaction was; ALL of the cowling is missing - significant, but I don't know why? The fan appears intact, is probably windmilling and without actually counting, it is difficult to see a synchronicity with either spool, but the vibration is horrific. The fire is bad, but certainly doesn't look like pressure fuel fed and appears to be in the 'hot' area of the engine. As an amateur, my gut says a compressor or even turbine BLADE has failed and somehow triggered a fuel vapour explosion inside the cowling, which is why virtually all the cowling has blown off. As always, Juan is quick to praise good work by crews and ATC and you can see why. With the exception of ATC stumbling over the initial Mayday call - which seems to me to be common - everybody did exactly what they should do. Juan also mentioned, obliquely, just how good the Triple Seven is all round. Great vlog Juan, as always.

  • The Colorado event appears to be strikingly similar to recent PW4077 fan blade-related failures in which inlets or cowling parts detached. These include an incident on Feb 13, 2018, involving a sister aircraft to the most recent 777-200 mishap, in which the No. 2 engine failed 30-min. before landing while en route from San Francisco to Honolulu. The NTSB cited shortcomings in Pratt's inspection processes for setting the stage for that accident. More recently, on Dec 4, 2020, the No. 1 engine on a Japan Airlines 777-200 lost a fan blade shortly after takeoff on a flight from Okinawa, Japan to Tokyo. In the wake of the 2018 incident the FAA issued a directive in March 2019 requiring initial and recurring inspections of the fan blades on the PW4000. It is not yet known if the blades involved in the United 328 event had been through this inspection. source-- aviationweek.com/mro/safety-ops-regulation/ntsb-fan-blades-fractured-ual-777-engine-incident

  • On 20 February 2021, a Longtail Boeing 747-412BCF, registration VQ-BWT, operating as flight 6T5504/LGT5504, had an engine failure above the village of Meerssen, shortly after taking off from Maastricht Aachen Airport on the way to John F. Kennedy International Airport. Dropped turbine blades lightly injured two persons on the ground. The plane was able to land safely at Liège Airport. The 747-400BCF was powered by PW4056 engines, a derivative of the PW4000 engine

  • Can't see the entire engine from the video but it wouldn't surprise me if this ends up being a contained failure. That orange material surrounding the fan case is made from Kevlar and designed to absorb the energy from a slung blade. The vibrations alone from a fan blade failure at takeoff power could shake things enough to cause things to break, and the boundary layer airflow would take care of the rest. It's times like these that proves the aircrews are worth every penny that they earn.
