This is the story of west atlantic flight 3319. On the 4th of june 2019 a cargo boeing 737 was on the way from Oslo to brussels. On this flight the captain was in the right hand seat and he was watching over the first officer who was completing his command upgrade line training. The first officer would have his hands full today as there was a thunderstorm around brussels airport. As the jet approached Brussels the pilots could hear ATC reoruting planes around the active weather system. Their weather radar showed them what was causing all this commotion, a pretty bad storm cell near the airport, but the south east of the airport was clear and so the pilots decided to make an approach from the south east. So the pilots went about prepping the plane for an ILS approach to runway 25R. The ILS or the instrument landing system is a godsend as far as pilots are concerned, it allows the plane to follow radio beacons on the ground right down to the runway. It allows pilots to land in bad weather when the runway isn't visible. In the cockpit the pilots were prepping the plane for the landing and they were talking about threats and issues that they might face on this landing. But unknown to them no amount of preparation would be able to help them deal with what came next. At 6:46 pm the pilots heard a loud electrical clunk and immediately the EFIS displays on the left hand side went dark. Whatever had happened also took out the autopilot and the autothrottle. The EFIS or the electronic flight instrument system has two screens: the Electronics attitude director indicator and the electronic horizontal situation indicator. You dont need me to tell you that those are important in the cockpit and these pilots had just lost some of their instruments for some reason. The captain who was moniroting the progress of the first officer immediately took control and manually started flying the plane. But there was a problem ATC could no longer find the 737 on their radar scopes, the transponder had failed. At this point the captain did not know if something else, something much more crucial might fail and so he declared a pan pan pan and asked for priority for runway 25R. As the plane made its way to brussles, the pilots took stock of what was working and what wasnt working. To their dismay they found that both the control displays of the flight management computer were working and in addition to that they had a barrage of warnings telling them that all sorts of things were wrong with their plane. From the number one aft fuel pump to the pressurisation system to the yaw damper. Something was seriously broken with this plane. Since they had the EFIS displays on one side they decided to fly a manual ILS approach. As the approach continued the captain told atc that they had had a severe electrical issue and that they were upgrading their pan pan pan call to a mayday. They wanted to get this jet on the ground as fast as possible. As the plane approached brussels they were a bit too high but they were able to intercept the glideslope from above and they continued with the landing. As they flew the approach the captain noticed that the EGPWS or the enhanced ground proximity warning system was not working. Great another thing that wasnt working but what truly worried him was the weather cell near the airport. It was described as a wall of water with lightning piercing the clouds every 20 seconds or so. This landing would be hard without a massive stormcell nearby but that was the situation that these pilots found themselves in. When they were just a miles away from the safety of the runway the rain engulfed the airplane and the pilots had to go around. The captain had no idea how much thrust he needed to use to carry out this go around so he just estimated it and thank god it worked. The plane started to climb and the captain put the plane into a left hand bank. As he did that the first officer set the transponder to ATC 2 and now ATC could see the pilots on their radars again. As the pilots orbitted brussels they noticed that the transfer bus number one circuit breaker was open the pilots debated on - Věda a technologie
I would rate the pilot’s flying at a 10. They had good instinct and utilized good crew resource management. I would love to see more of your videos about airplane crashes.
Yeah, major kudos to all flight crew, AND it's nice to see an incident that strongly suggests that the airline in question has very good training.
Definitely 10/10. They did not cause this fault. Their training and judgment kicked in the o save the plane. The minor mistakes are just armchair hindsight. Their passengers walked off instead of being carried off. Respect.
It was a cargo flight so no passengers but yeah, respect
Captain MACI releases new videos every 5 days.
What I would like to know is what was changed so this does not happen again?
I mean things do fail, but the fact that a power bus failure can turn of THE warning system which is supposed to warn you about a power bus failure seems like something that could be designed better.
Pecka.
To make sure this does not happen again, technicians put some "sellotape" round the power bus to stop it turning off the warning system.
@@redblade8160 yeah, cellophane tape! I use 'duck' tape myself.....shite happens--shame....
Better system integration. Current airbus systems can withstand even 3 generator loss. And pilots are trained to handle such situations in the Sim, its called emergency electrical config, its one of the hardest Sim sessions as the procedure is really long and requires a deeper understanding of electrical systems
Yes, please make a video about the same plane over England, as an electrical engineer this stuff fascinates me.
I also would love to see a video on the other incident this plane had.
The crew did a remarkable job dealing with a corner case failure, absolutely a 10.
Would enjoy seeing a video on the other incident you mentioned involving that same aircraft. Great job on this one. 👍
I'm definitely curious about the second electrical issue with that plane. Also, my dad loves your videos. He used to give me the safety bulletins he got as a private pilot to read when I was a kid. I used to read those things avidly. He says it was to keep me quiet. I say he was trying for a third generation of aviators in the family.
The pilots got their plane down safely with no damage or injuries. I'd say that's a 10!
Jeez... You would think that the XFR BUS fault light WOULD RECEIVE POWER FROM A DIFFERENT SOURCE! Even the saab 340 was smart enough to do that
.. Things powered from one source with faults and warnings coming from a different source.
Any time you can keep the greasy side down is a 10. That said, I'd like to know the hours and qualifications of the pilots as they seemed to go above and beyond to prevent a crash. Whatever their actual training, the flight deck crew was cool and smart. They didn't stop flying until the plane came to a complete stop!
An example of why a Flight Engineer should still be on aircraft. The electric systems would have been very familiar to them.
IT WOULDNT BE HARD TO HAVE OFF PLANE LIVE STREAM FOR STUFF LIKE THIS.
HAVING A THIRD SET WOULD HELPED.
Pilots are trained for situations like this and situations much worse than this like the emergency electrical config aka 3 generators lost
The captain did the right thing, given the information he had. He took an ultra-conservative plan of action that, given the knowns and unknowns, kept everyone safe.
Conversely, had he had an intimate knowledge of the electrical system, but elected to not attempt to remedy the failure, he would have put people in grave peril.
Unless you know and understand the consequences of your potential actions in this situation, it is a grave error to "try this, try that", because you could inadvertently cause an unrecoverable situation, killing all on board.
I'm a EE myself, and despite all my 30+ years experience, I would have done exactly what the captain did if I didn't know the system. The *last* place to experiment on the electrical system is while the plane is in the air.
Even with the slight landing misconfiguration, both the Captain and FO did a stellar job. 10.
Yeah agreed, in all honesty a misconfiguration for landing isn't really a safety issue at all unless you are completely on the wrong end of the misconfiguration you are intending to do.
I appreciate the videos about planes that had something go wrong but was able to land safely. Really showcases how much training and skill the pilots have.
That was some superb flying they did that saved their lives and their aircraft. Definitely a 10. Would certainly like to see the video of the other incident mentioned. Keep up the good work.
This is why standby instruments are important! The standby will either be "steam" gauges or a small PFD that has it's own internal battery. Also, typically when a generator or bus fails, it will impact only the instruments on one side (i.e. Capt or F/O side) as the other side is powered by the second bus (I think 737s are all like this).
PFD? F/o?

Do you realize not every viewer of this channel is not a Sully like you. I doubt if Sully were here, he would be so hip and cool as you. using aircraft acronyms. He would understand as smart as he is, he would not try to show up others using terms like GA. EFB, TOGA, FO. But you are not him you need to prove what you know.
That type of person is known as a know it all or smart ass.
Pilots did a good solid 10 in a very stressful environment. Sometimes you earn your whole years paychecks in 40 minutes.
i give them a 10. A situation they had never seen, never practiced, bad weather, and they put the plane down safety. I'd love to see more!
The pilots, and you, get a 10!
Wow, awesome video! Also, I think the pilots made the right choices with the info they had. I can't imagine the pressure it would be if they really had to divert, even with navigation it increases the pressure on the pilots, without it + the plane losing systems one by one it seems to be impossible.
I've had crap fail in IT, where in theory you do X to fix it, but X has already failed, and you think a reboot will fix it, but I've had systems go from repairable to non reccoverable during a reboot.
Excellent description as ever and yes this type of incident reports are very interesting and gives an idea of the complexity of interfacing systems that have to match and work together to make aviation safe 👍
Congrizzles on the patreon, fren! As for the video, having grown up around aviation since early childhood, this really made me nervous. Thank goodness that the pilots made it onto the ground safe and sound.
I love how you turn technical terms into language that I can understand. Thank you!
being someone with years of Relay experience i can tell you what the 2 main failures that can occour. 1: coil burn out. Usually on relays that are in an energised state for extended periods (could be thousands of hours ) Coils heat up when energised. Wires may have tiny defects causing localised heating leading to either failure of said wire or melting of insulation coating on wire causing a coil short which would trip a protection ciurcit such on this episode, and also cause a denergisation of relay through either the magnetic field produced is weaker or insufficient to overcome the detent spring or current fails due to a protection cut off on that circut cutting power. Other failures involve arced contacts on the springleavers which normally cause non conductance or possibly over current as the increased resitance from the carbonised contacts may also cause extra arcing till that contact is unable to counduct current . usualy if you wanted some form of warning for a real simplest set up is using one of the make contacts( contected when relay energises) or a break contact ( open circuit when energised) either can be used depending upon the type of detection you require.
That could have been so much worse than it was. I cannot stress enough how important it is to retain the basic flying skills from flying small aircraft. And to not become dependent on automation. On a scale of 1 to 10, I rate this an 11.
I want a video on panam 707 crashes in the 60s. Nearly a dozen!
I'll give 'em a 10. Whoever drew those thunder clouds gets a 10 as well
Fantastic video!
10. To be fair, I live in Brussels. Those pilots might have saved my life. I can only applaud!
I would love to see more about this plane. Thank you!
Deffinetly a 10 for the pilots and yes a video on the other incident u mentioned in this video please 😄 great video and excellent channel
The pilots did an amazing job with what they had. Plz make the other video. Great job 👏
good content, thanks
The pilots did 11.... imagine driving a car blind folded without any warning or training.....ya...that well
Remote control
Your videos are great
Great channel.
Love the stories of successful landings with the odds stacked against them! These are the pilots I want flying when I'm onboard.
They did very well. I'll have to give them a 10. They couldn't avoid a high stress environment one way or another.
Please make a video of the incident over England.
Thanks for your videos.
I like when you combine videos for planes with multiple incidents
The pilots get a 10 from me as well.
Operating on limited information, they made the best of it without taking unnecessary risks.
I do think though, that this falls firmly into a large number of cases where I wish there was still a third flight crew member - an engineer. Someone intimately familiar with the mechanical nature and systems of the plane. While it may be more economical to automate engineers out of the cockpit, I've never once read or heard about an emergency situation where not having an engineer was a benefit, rather than the absence of an extra pair of hands and an extra skilled professional who could help.
Brilliant.... 10/10 the crew did a tremendous job
both pilots did a 10/10 with what instruments they had.
I give the pilots a 10/10 for not crashing into my house and 0/10 for not crashing into my neighbors house 😇
Relay from 1985? Why was it even allowed to be fitted?
Is it my imagination or is this guy becoming more prolific? Seems like I always have a new video to watch. Great channel.
I really liked this video. The pilots earned a big 10,worked great under pressure.
please make the video of the plane over England that you reference in this video. I'll check out your patreon too, maybe add you into the monthly. great job as always.
Ok, I think I successfully joined your Patreon.
Pilots got the plane on the ground. Everyone on board walked away.
10/10 would recommend them for my flight.
Thank you
10, they did a great job, kudos
This, is the story, of MACI flight IHV200K, flown by Captain MACI in a TU-144, from Tuxtla (TGZ) to Lincoln (LNK.)
Yes, more!
Love your channel
If you stated “a lot more worse” to trigger comments then you’ve succeeded.
Minor language errors aside, another excellent presentation.
MOAR! please!
I guess, u could argue to subtract 0.5 points for the misconfiguring for landing. However, considering they got themselves and the plane down without a scratch, I would add 1.5 points for that, so an 11 from me! Or a 10, if Im really not allowed to go above 10.
Absolutely a 10!
I would rate the skills of these piolts in the incident 20 out of 10. The guys took a very bad situation stayed relatively calm and manged to land safely.
I live just off the approach to the south-east runway at Brussels, and I am writing this from there. At 7 pm on 4 June 2019, I would have heard this flight passing nearby!
Make the second video...where the pilots made the correct decision was to stay at the airport they were engaged with. How many times have you seen crashes when pilots choose alternative airports with problems with their planes. Then crash enroute or landing because the clock ran out. If it possible to get the build history on the plane that would be interesting. If you have the "N" you can look it up easily. Even crashed aircraft. You sound like your getting over your crude. Congrats on Patreon...keep them coming.
What’s the “N” word?
@@kickedinthecalfbyacow7549 N number. ID Number for the plane
@@thereissomecoolstuff oh, I think you mean registration, you do know that only some planes reg stats with an N
@@kickedinthecalfbyacow7549 yes registration. Yes some do not have "N" registration...
@@thereissomecoolstuff that’s why no one calls it the “N” word……
Do The One Over England
No, do the one over America
🇬🇧🙋🏾♀️Fascinating 🖖🏾
More please 👏🏾👏🏾👏🏾👏🏾👏🏾👏🏾💜❤️💜
I think they did a great job!
We obviously need the video about the other incident! I'm still new to this channel so I'm watching old videos too... 😅
The power generation didn't fail... The distributor of power did.
This is actually a common theme with what I would argue are most electrical systems.
Because the public mostly just hears 'conserve power' they often assume it's the power generation capacity that is responsible when in fact much of the time it's the capacity of the local distribution grid that is stretched to the limit.
If you've ever blown a fuse at home due to plugging in too many appliances you should know this. There is plenty of power outside, but your home outlets can't take that much consumption at once.
In this case there wasn't an overload of consumption but still by accident the bottleneck was the power distributor.
Put your patreon in description of each video in addition to the CZcams about section also do a community post if you haven’t already is my advice wow important topic making travel safer…
difinitely a big 10!
10+! They had no way to know what was going on, but they didn't panic which would have made things worse.
YES PLZ MAKE THAT VIDEO TOOOO
These pilots did a great job, no question. 10 out of 10 from me.
What an amazing crew! Now we know why that Captain is a line Captain. Give that man a raise!!!
Ah, the ol' "You didn't get a malfunction prompt because it wasn't powered."
Hi 👋 the pilots did a good job with this jet👍🏼 would you possibly do a video about the tupelo Mississippi incident with The Beechcraft king air 90theft? What does it take to start The aircraft and fly it?
Video suggestion: China Northern Airlines flight 6901, which crashed in northwest China in 1993, for ridiculous reasons. The plane was a dry lease, and its English-language annunciations were unfamiliar to the crew. They dialed in the wrong altimeter setting, so they were too low approaching their destination. The GPWS sang out "TERRAIN PULL UP" (in English). The pilots asked each other what the message might be telling them. And they didn't pull up. It would be comical if it weren't so tragic.
I would absolutely love to hear about the same plane having the same problem a different time. Was it after this incident? Had they learned from this one and applied that knowledge to the next? Or did things get lost in paperwork?
I'd rate the captains flying as a 10. You stated the crew had not been trained on dealing with electrical issues like this. That means they also did not know how to recognize them. To the crew, their systems were just randomly starting to fail. They had no idea how to fix it. And no idea how many more systems would fail. In their minds, they were on a timer. If they did not land at this airport as soon as possible, they would crash. Which would not only kill them, but possibly people on the ground. If anything, they were hoping to crash on the runway with emergency services on standby.
I'm glad they made it down safely. But I do think there's an issue having the warning for an electrical/relay fault connected to the same power as the thing it's warning about...
Thats why transistors (or triacs) are much better than relays. Relays are working mechanically. Transistors can do a same job without any moving parts. More of that - relays are much more sensitive to any g-load - aven best ones. If transistor is mounted correctly (not standing on original long pins like in chinese products), then it can work for decades with insane g-load.
Yup, power transistors never fail ... LOL. These three phase transfer relays are huge. Each engine generator is able to supply up to 90KVA.
@@ImperrfectStranger in case of AC - triacs.
The flight crew was exemplary in their airmanship: they were dealt a hand that they had never trained for and got the aircraft safely on the ground.
I'll give the pilots a 10. Plane not lost, walked after the landing. Sure things can be better but no loss of life no loss of property, that's a 10.
I'd love to see what happened in the other incident, too.
10, difficult situation, difficult weather. They could have tried swapping systems/bus, but given the information they had on hand, and the failure indication light not working, they were better to leave well enough alone while they were still able to fly with what they had left.
Imagine flipping a few switches and losing even more systems, or radio, or ILS guidance.
I rate it 11 these men are not only brave calm and kool headed 5hey should get a award or medal something
Any plane that can be landed safely amidst a crisis is exemplary!
10. They did an amazing job.
I've read about a plane crash-landing (spoiler: everyone survived) in GDR on December 7. 1963 where a plane suddenly lost all electrical systems. Turned out a generator failed. But wait, it gets better. The plane HAD a battery backup, but no indication of its enabling whatsoever. So neither did the pilots know their generator failed, nor did they know they were running on backup battery nor was there any warning that the battery was running out. Classic design screwup. See Flugunfall bei Königsbrück.
Always a difficult decision, land with what we know works or try making changes that could make things worse. In good weather I’m sure they would have gone into a holding pattern and done some trouble shooting and possibly switching to a different bus. Or they could have done that, been unsuccessful and had the weather close in around them. Always a tough call but they got the plane down undamaged so they must have made one of the good calls.
"Deuc'd close-run thing", handled very well. Although it would not have done any harm, (if I interpret the commentary correctly), leaving the breaker alone was a prudent decision. If you're not completely clear about a situation or the system, don't make a bad situation worse with panic-stricken "fingerpoken und mittgrabben".
Maybe airlines should devote more pilot training to electrical and system engineering topics?
Everyone walked away. I’d say they deserve at least a 10. And yes do the other video for us.
I rate the pilots a 10. They did the best they could do. Btw, although the transponder failed, the primary radar should still have picked them up, however without id label on the radar screen. And when I understood that right, the system that should generate and display an error message that the right bus had failed because this system was also powered via that failing bus? That could be considered as a design flaw... Great simulation! When you flight the ILS rw 25 (r/l) you approach the airport from the north east, not the south east as you said...
the pilot did perfect, 10/10
I give them a 9 out of 10. I understand the stress of the situation, but a little more checking like selecting a different transponder setting could have made this less dangerous. Not being visible on radar in congested airspace means the controller could not keep them clear of conflicting traffic. With all the other failures there is a good chance that their onboard Traffic Collision Avoidance System (TCAS) was not working either. Since it operates in conjunction with the transponder means no transponder, no TCAS. Otherwise an extraordinary job by the two pilots.
Since the visual is a 737 not -200 I was wondering what the make of the aircraft was. It wasn't until the end of the vid when you mentioned that the part was manufactured in 1985 that I sort of maybe figured that it could've been possibly a 737-200.
They done a great job 10 out of 10
love it when he say: This is flight 139
good job..however you probably wrap up with what the manufacturer and FAA are going to do to ensure this could not happen afain on any A310
Now on to more serious matters - where is my parcel?
With what instruments they had, I give them a 10000 on the 1-10 scale!
I would give the pilots 10/10, landing a cripled plane in a storm with no fatalties, superstars.
Please bring us the video of the other incident on this plane.
I mean, the pilots safely landed a crippled plane with no damage or injuries in a busy airspace. Hard not to give a 10/10
Its just Pan-Pan not "pan pan pan", Pan-Pan may be repeated 3 times, but in reference you only need to say it once. Love your videos!!
10:50: A very solid 9! I wouldn't have even done 4 😅... Maybe I'd do a 7 after being trained as a pilot.
