What strikes me as tantamount to criminal negligence is that for *22 years* the repair and rivets were seemingly *never* checked with sufficient attention to show their slow decay! 🤦🏻♂
The problem is, the rivets were OK, and the cracks were behind the doubler, so not visible. The only way to inspect would have been to remove the doubler.
@@rapzeh4 I see what you mean 🤔, but it remains true that nobody seems to have checked things thoroughly enough. I guess 21+ yrs of it holding up made for complacency. 🤷🏻♂
Two words: Chy Nah
@@Danielfucks69China Airlines is the national flag carrier for Taiwan, not the country you call Chy Nah.
@@rapzeh4 Was there no way to do an x-ray of something along those lines? Anyhow, China Airlines should have paid for a Boeing engineer to be in Taipei to oversee their repairs.
Jesus this one was so sudden it's terrifying.
Just like Japan Airlines 123, a minor flaw left unfixed only caused destruction years later.
RIP to all the victims.
the fligh that because lost of hydraulics?
@@patogenify Most of the tail came away, also due to an earlier tail strike, leaving it flying erratically for 30 minutes, while everyone aboard including the brave pilots knew they were dead.
The difference with Flight 123 though is that Boeing was to blame for the inadequate repair, not Japan Airlines.
@@jdmguy44 True. Rear bulkhead. Equally horrific for all, if not even more so.
@@pomerau no. u wdnt stay conscious 30 minutes without oxygen
22 years are a really long time (older than me) and no one noticed it more than two decades. This must be one of the longest chain of events that let to a tragedy 😢.
That’s what I’m thinking. 22 years is a LONG time for that repair to hold with no issues. While this is a tragedy, it seems like little more than just an unfortunate accident.
patch it for 22 years i say its already win solution, and there are no proof following boeing guidlines will hold for 22 years, i thinks a plane need convert it to cargo plane after 25-30 years of span life, do not carry passenger anymore
@@billykulim5202 what if this plane did get converted would it still break apart?
It's a long time, but 20 years goes by in a blink of an eye.
Yep especially nowadays. Time evaporates so quickly.
The view from inside the cabin is always a terrifying thing to see. I can't imagine how the pilots feel when they realize they're done in this world.
I Should Imagine that the Passengers would have Passed out Rather Quickly given the Altitude.
Imagine the view of the passengers that were seated in the rear of the plane when the tail section broke off.😥
@@jamesrau100nightmare fuel. Very saddening and sobering that people no different from you and I, had to experience such a thing.
They did die instantly
@@framedthunder6436 They certainly had enough time to know they were going to die, before they actually did.
As an Taiwanese, we called this disater as one of the four-year limit of China Airlines. The four-year limit happened in between 1969-2007 and this one is the second most deadist among those accidents. R.I.P those who died in those years.
Could you tell us more? What were the other 3?
@@jakec28 During that time period, China Airlines had so many crashes it averaged out to be once every 4 years. The 90's and 00's were an especially bad era for its passenger operations. Look up CI 140 @ Nagoya in 1994 and CI 676 @ TPE in 1998.
always not the actual aircraft featured.
Amazing that it lasted 22 years before catastrophe failure
Far longer than JAL 123’s 7 years before the entire horizontal stabiliser went
@@filledwithvariousknowledge2747-- CI's 747s weren't used for exclusively short-haul. As such, it didn't undergo the pressurization cycles JL's 747s did.
This is why you'll never find me on a plane older than 5 years.
Which is ridiculous. I direct you to the Max planes, and I think the DC-10s, too, were fairly new.
7:08 Boy, Orient Thai Airlines sure dodged a bullet.
Quite the understatement.
You wonder too what's in those people's minds to invest in an aircraft that is on the brink of collapse. Either the damages were invisible or they are just as negligent as China Airways
I was recently on a flight out of Charlotte Douglas International Airport. We took-off and everything seemed normal. I thought it was odd that I didn't hear the gear come up. Sure enough, after several minutes in the air, the pilot announces that there is a problem with the gear and it's refusing to come up and we we're going to return to the airport. The videos on this channel flashed through my mind for a brief second, even though I fully expected it to be a routine landing, which it was, of course. In decades of flying, that is the first time a flight had a problem and had to turn back. Love your channel! Keep up the great work.
I would be exactly the same I'm sure and this particular video makes me think I wonder how many flights we've been on with a dodgy maintenance shift yet the craft manages normal operations with 10s of thousands of passengers and we've been lucky missing a disaster? 👍
Sometimes the RUclips contents flash through your last moments of life. And you also imagine being part of the “rip of the XXX souls perished in flight XXX because of repair crew error on the landing gear…
To not see it is maybe even more scary like the more than 200 people did....
What is actually your reflection on the Taiwan disaster?
I was an aviation structural mechanic in the USCG and it was common knowledge to remove all the damaged skin. When I saw the repaired area I thought it was just the temporary patch, not the completed repair.
@chuckgladfelter
How was it possible that so many ground crew inspectors NEVER caught the damage OUTSIDE of the double plate repair area for all those years? Seems IMPOSSIBLE for all of them to not notice the corrosion and scratches!
@@watershed44 They assumed it was a proper repair. Anywhere there is a deep scratch on aluminum or a crack that isn't drilled, deburred and patched is a potential problem. The scratch made the skin weaker.
i dont get why event like this are blaming on aviation company, as i know most repair airplane like this has boeing or airbus enginer there, in every country
@@billykulim5202 Simple China Airlines did not follow Boeing Standard Practices Manual. TWA was their on call maintenance. We called the China rep You Sign, You Sign. I told him I could not sign off a wright up that did not meet MEL requirements. Then there was the time we almost burned the Bradley International Terminal down. They could not start #2, two tries. As I was getting two the gate a third attempt was made. There was a fuel fog exiting the tail pipe rising to the wing. It ignited in a BLEVE (boiling liquid expanding vapor explosion). Then flames out the pipe. The ground man called a shut down. I radioed our engine man on the way to the cockpit. You Sign, You Sign was be hind me with Mr. Wong he fix, he fix before. Mr. Wong called for a start. He was watching TGT. The ground man called for a shut down "ITS TORCHING"!! Mr. Wong guarded the fuel cutoff. The TGT was not going high because the flame was not in the turbine area. "SHUT IT DOWN ITS TORCING!! SHUT IT DOWN THE WING IS ON FIRE!! The bottom of the wing was badly scorched and the left inboard aileron had burned and missing composite structure. I do not know who did the repair.
The aileron had a heavy aluminum doubler top and bottom. It left on a revenue flight. I wonder if You Sign signed that one off. Does that give you an idea how China Airlines operated in those days.
A plain doubler is not the way Boeing usually calls it out. They usually are stacked doublers to carry the load out to the ribs and stringers. I would think a re-skin in that area might require shoring. "There is never enough time to do the job right but always enough time to do the job over. Hershel Cotten. (Flown West)
10:19 That'd be awful to be in the cockpit and see your doomed airplane's own shadow falling toward the ocean.
@billolsen4360
I get the feeling that there IS black box audio of the cockpit crew in the final minutes before their deaths but they didn't release that audio for obvious reasons. I say give those men their dignity and don't let their fear be heard in vain.
@@watershed44 According to a cursory Google search, the cockpit voice recorder is generally located in the tail of aircraft. Therefore, as the tail detached from the aircraft before the front portion of the aircraft impacted the water, it is unlikely that the final dialogue between the crew was recorded.
I also am horrified to imagine the passengers in the tail section strapped into their seats watching the front half split away from them and seeing the earth as they plummet toward it
@@TheIronDuke9 Yes, I can't imagine the terror they experienced as they plunged to their deaths. God rest their souls.
@@TheIronDuke9Landed quicklier than anticipated- RIP!
RIP all the 225 people on the flight. Great work man keep it up
I’ve always considered this to be one of the worst ever cases of negligence and incompetence. A plane actually splitting in two must be beyond terrifying. And for it to happen to a beloved 747 is tragic. RIP everyone on board. I’d like to know if that sorry excuse for a repair crew ever had any shame, guilt or remorse for their laziness 🙁😭😡
Probably in retrospect, one would hope.
But actual guilt would require intent, whereas was was present was negligence in the main.
I'd even ask: Did Boeing send an Inspector (certified in their approved repair techniques) to VERIFY the proper repair ?
@@psalm2forliberty577 The airline should have called on a Boeing engineer to be on site during the repairs and/or Boeing should have initiated such a visit.
@@billolsen4360
100% agreed.
I'd guess (evidence show here) suggests that didn't happen.
Probably they let emails & pictures of repair be enough, except long term, they weren't.
The crew themselves would not have known that they were making an improper repair. It was the engineer in charge who would have been negligent.
Blaming the repair crew is like blaming the operator of the asphalt spreader after a road collapses.
This and Alaska Airlines 261 were a couple of the most preventable accidents. My heart goes out to the victims & the families of these tragic disasters. 🙏🏼
Very upsetting when these crashes happen due to negligence as in this case. RIP to all who died and hope their families/friends have found the strength to continue their lives.
Echoes of JAL 123... RIP.
Well done again and thank you.
Alec?
@@dianegreer2789 Oops... forgot where I was. Thanks.
Wow! I love how you showed an animation of how exactly the repair worked- it really helped me understand better. I have an interest in air disasters because I’m curious about how airplanes work, and your videos tell what happened very straight and precise- no dramatic music or long intros. Great work as always!❤️
SIMPLE graphic. So often missing from stuff like this.
I can't imagine the horror the passengers felt when the plane broke in two while they were at such a high altitude.
Unfortunately, in this type of accident, long experience and high skills are useless.
RIP
My guess is possibly a great number of the passengers were pulled out of their seats into the air jet when it happened.
is should be around climbing, so is likely most of passengers are strapped
'Fortunately' the passengers would have known little about it, depressurisation at such altitude would have been pretty instantaneous... I would argue the pilots wouldn't have known much either being in the same unpressurized cabin.
@@themanof83 we can only hope
I have flown on this exact aircraft three times, travelling between Taipei and Tokyo, the last time being about one year prior to its disintegration. I know this because it was the only 747-200 left in the fleet for three years prior to the disaster. China Airlines was having a lot of issues at the time (during the 90's), including deferred and improper maintenance. They were later placed under Singapore Airlines management which resulting in a turn around. They are a respectively safe airline today.
God Bless you for your services.
@@darrinsiberia How do you know what services they provide?
@@krashdhe can't?
@krashd I think it's a misunderstanding. They assume he was a pilot.
@@brownkorean I flew on it as a passenger, not a pilot. I am an engineer who has lived in various countries in Asia. I was flying China Airlines at the time because I was living in Tokyo and going to Taiwan every other week for about 6 months, and China Airlines was the cheapest and flew out of Haneda (instead of Narita).
Well Explained...Thanks TFC..
RIP to Those 225 Lives
I was riding China Airlines Boeing 747-400 10 times from Taipei to San Francisco and once to LA
Flew them many times (18, I think) from 1993 to 2012 from SFO to BKK. Often wondered if I was ever on this plane. Never know when your number is up. Changed to EVA Air because they were a little cheaper & had a nicer Premium Economy.
747-200 not 400.
As awful as this was, 20 years between a repair and a catastrophic failure isn't that bad. I think part of the fault lies with no one in maintenance picking up on this fault over the intervening decades.
They covered the damage so removal of the boiler plate would have been needed to spot to crack propagation. You can't leave deep scratches in aluminum that's under stress as they will eventually grow into cracks. Anyone who works with aluminum knows that... or should.
@@blackhawkorg I think I recall a similar structural fatigue related accident very similar to this and they came up with some kind of method to routinely inspect for such hidden cracks on any plane undergoing such repairs (doubler plates, patches, etc). I cannot recall if it was ultrasound, something like that. You would probably know.
@@blackhawkorg According to Wikipedia:
"The D check, sometimes known as a "heavy maintenance visit" (HMV), is by far the most comprehensive and demanding check for an airplane. This check occurs approximately every 6-10 years. It is a check that more or less takes the entire airplane apart for inspection and overhaul. Even the paint may need to be completely removed for complete inspection of the fuselage metal skin."
Based on this information, it seems that the aircraft should have had this heavy maintenance visit well before the disintegration incident. This maintenance operation should have uncovered the faulty repair and then the proper repair should have been made. Therefore, the question becomes, did the airline perform a faulty D check, or did they fail to do a D check at all?
Yes they should have x ray’d the fuselage at that many cycles part of a non destructive testing done in D checks and the repair should have not been considered permanent and at least do eddy current inspections for cracks every so many 1000 hours
Rip to the 225 people who lost their lives in this horrific crash imagine being in the plane when it suddenly breaks apart and all U can see is the sea and the sky and bodies and the plane in 3 pieces absolutely terrifying

Kinda wild how poor maintenance can doom and aircraft 22 years later. I'm surprised how during that time nobody caught the flaw. Sad...
Pretty crazy it still functioned for 20 plus years…it lasted so long it was the only 747 left in the fleet. They almost got lucky.
@33moneyball
If only the plane could have held on one more flight, if it was being delivered only three crew would have perished.
The only 747-200 left in the fleet. This wouldn't have happened if it was retired earlier.
Imagine flying, and then out of nowhere, you hear a bang, and then you're plummeting down to earth at breakneck speeds while trying to save your plane, despite the fact that you have no idea that over 40% of the fuselage is gone. That's scary.
Originally repaired by engineers unaware of the correct procedures, and passed airworthy by someone who also did not know the correct procedures. So I have one question....what on earth are manuals published for, and repair instructions learned??? Pure negligence!!!
RIP the poor souls who passed in this horrific incident.
China man need no manual
Boeing one way or another should have been contracted regarding this situation for guidance and an inspection. During heavy maintenance why was this overlooked? The culture constrains Asians from speaking up.
This procedure wasn't done "By The Book".. There IS no margin of error when dealing with the maintanance of an Aircraft..
@qg3726
Those who signed off on that repair should have been criminally prosecuted.
@@watershed44 Which would yield a finger pointing sessions where no one would be held accountable.
@@deepthinker999 Don't be too sure about that, at least in some countries.
Reminds me of JAL 123 where they also have improper repair that caused the bulkhead to fail which severs the hydraulics controlling the plane. As for this video, they have to switch to another patch rather than the recommended one hoping that its better and bigger but even that has a flaw
That one failed far sooner after just 7 years after the tail strike but in the worst way possible, the whole horizontal stabiliser came off meaning there was no way to control the plane before it crashed
However JAL were not to blame for that. Boeing were.
@@jdmguy44 Well Said implying that Boeing's inspection of this plane may not have solved the problem.
So sad. In the beginning, when speaking of the flight crew they mention their experience. But no experience could have saved them. It angers me so when these tragedies happen because of poor repairs/maintenance. RIP 225 souls. Thank you for another great presentation.
Exactly. The pilots were powerless in this instance, no amount of experience could save them. This one hit particularly hard just because of how terrified those passengers must have felt in their final seconds.
Can i offer a suggestion? If your using an AI for the ATC conversation could you change the voice for ATC and the pilot cus it's kinda hard to keep track when theyre the same voice
Love how this is recommended while I’m waiting to board my flight
😄😅
All those poor people on board...I can't imagine the terror and horror.
Your videos are getting better every time. I love the level of detail and added features you're including with the explanations. The simulations look awesome. Good job.
ruclips.net/video/kFAwnsYZ0K0/видео.html
It's amazing how they can find out what went wrong afterwards instead of before the airflight happened.
Great video once again! Rip to those on board though
Amazing how all passengers survived though.
"Amazing how all passengers survived though."
Did they?
On May 25th, 1979, the American Airlines crash at O'hare airport in Chicago. The cause of the crash was due to mechanics using a forklift to remove and replace engines instead of following manufacturer guidelines which were to remove all the bolts from the engines connected to the pylon. This took too many man-hours to do costing the airlines a lot of money in maintenance costs. This was pure negligence on the part of AA and other airlines that followed this easy way out and time saving method of repairs. This crash was completely preventable IMO.
@jbenthere627 It is not quite as simple as you state. The correct procedure was to remove the engine from the strut first and then remove the strut from the wing. The procedure used in this case was to lift an engine stand up to the engine with a fork lift, attach it to the engine and use the fork lift to support the engine while the strut attachments were separated from the wing with the engine and still attached strut then being lowered to floor level. They might have gotten away with it if they had not gone for a break leaving the forklift still attached, the forklift sagged in this time resulting in a jolt when the forklift was powered back up and it was this action that did the damage to the engine strut.
Oh wow I was surprised to learn it held up for 2 decades! Planes are sturdy things.
It's so tragic how such a improper repair of something that seemed small could take so many people's lives.
Excellent video, illustrations, and real photos! Thank you for putting everything into layman’s terms so we can understand.
Love TFC ❤
Sorry, what? Riveting around an already damaged area?! 😮 These people called themselves engineers?
As I recall, Taiwan cleaned up its airline industry after this and is now has one of the best records.
It ALWAYS takes a loss of life before the needed changes are made.
@@deepthinker999Except in this case it took multiple accidents and a staggering loss of life. And had CAL 006 gone down over the Pacific in 1985, the numbers would have been even worse. Fortunately CAL has been a safe airline for two decades now.
amazing that the shoddy repair held up for that long.
I cant imagine their terror. RIP
Impressive work again, TFC!
I miss AirCal. You used to be able to fly between L.A. and S.F. for $12. Plus the planes had a great color scheme.
Doubler plate used was made of Chinesium instead of Aluminum for cost reasons
That must be a terrifying fking last couple minutes of life.....falling straight down from 30,000 feet knowing aint jack schitt you can do but watch it happen.......
10:00
Imagine the hopelessness at this point 😖
The mechanics should know the history of repair and each service time should check around the damaged area (most likely already over-stressed); the frame stiffeners may have been over-stressed also though no robbing involved and no visible damages from initial scratching.
Saddest thing is that this was the last flight before the plane would be sold off to another airline, if only the plane just lasted just a few hours longer. 22 years in the making. RIP
Not sure to understand, if the plane had lasted few hours longer, the buying airline would have had a doomed airplane in their hands anyway and most likely, the plane would have crashed.
Ye but the workers handing the plane off to the airline would (hopefully) have seen the damage
@@christopherweise438but then it'd be a freighter instead of a plane full of passengers. Either way the pilots were goners.
@@christopherweise438 why's that better? China airlines was the one who f'd up the repair, why should it happen to the other airline?
@@quadrram3945 he's not saying it would be better lol hes just pointing out that if the china airlines workers who would need to inspect the plane before handing it off to the airline didn't do their job then the plane would still have crashed but with the other airline
Very well done, Flight Channel.
It's just so sad and make me mad every time I find that the accident and the losses of so many lives, was caused by the negligence of supposedly maintance people, how can they sleep at night??? when they caused the death of many passengers
I truly believe that the maintenance people were unaware of their mistake. The blame rests with the airlines management on multiple levels.
I recall this quite clearly. I was to fly to HK from Kuala Lumpur in December 2002 with China Airlines, and had doubts if I should cancel my tickets following this unfortunate event.
Watching the plunge from the cockpit was horrifying!
Wow I would’ve expected that thing to collapse after a few flights. I’m 22, that’s my entire lifetime that it survived which is significantly longer than I would’ve expected a faulty repair to last!
Similar tail strike happened on JAL 123 seven years before it crashed. That is wildly known for causing the deaths of 520 people.
Especially since the Japanese government would not allow rescue operations to begin for (19) hours after the crash. The U.S. military offered their services on site in (2) hours after the crash but were denied by the Japanese government. It is generally believed that passenger lives could have been saved by a prompt emergency response. Took a bad situation and made it worse.
Scary how similar the two midair breakups were. Both 747, both tail strikes, both inadequately repaired. The JAL maintainance head committed suicide after the cause was identified. RIP
Nice video. Thank you. Three issues here: 1. When was the last heavy "D" check done on this aircraft? There should have been one sometime after the 1980 tail strike accident, considering how many years passed before the fatal breakup. If not, the airline was deficient in not performing one. If one was performed, the inspection crew should easily have found the propagating cracks, and I would question their competence. 2. You never go against the manufacturer's advice. If Boeing, Airbus or Embraer tells you how to repair something, you follow their procedures exactly and you can even ask their engineers to look at it after you're done to make sure you did it the correct way. If you want to ask questions so you understand rationale and tradeoffs, great, but do what they tell you to do. The manufacturer's recommendation will very rarely not work (and will be better than what you do) and if it does fail, the manufacturer will be liable. 3. China Airlines' management, frankly, should have refrained from running their mouths off and displaying their egos. When you screw up and people die because they flew on your planes, own it and fix your procedures and your culture (humility is really helpful in these situations) so that mishaps are less likely to happen again.
@ronaryel6445
I sure do feel for the families of the lost souls onboard that plane.
As with the Boeing 737 MAX where the pilots were never informed of the software changes resulting in passenger loss of life? I smell someone who was too cheap to provide the necessary training at Boeing.
@deepthinker999 Wouldn't be the first Chinese corruption scandal, especially given the time frame involved
I love watching a YT commercial right before impact
The inspector who signed off on the repair work must’ve said “ ok, it’s good as new”
The negligence on the part of the maintenance workers makes me sick. They should've done what the manufacturer said to do and all those lives would have been saved. Disgusting.
@b.t.356
What's worse is all the subsequent staff that kept seeing that area of the plane rusting underneath that plate as well, I can't believe nobody ever took a second look at the corrosion outside of the plate and didn't speak up! Incredibly disgusting.
It would be so messed up to have a seat in the aft section, and suddenly you see the plane break into two pieces, and the forward section flies off in front of you ...
@@denniswilson8013 No, you'd have a minute or two of consciousness even at 30 000 feet (look it up), and up to one minute at 35 000 feet .. and the messed up part is, that even if you do pass out - you'll wake up at some point as you descend into thicker air. o.O

I remember a time when China Air was not allowed to land in the US. They could fly to Honolulu. They had the worst record of flying problems.
PRC indeed had a bad record of performance but with the help of the USA they cleaned up their act and are now well regarded. Carriers from Indonesia had a terrible track record and were not allowed to land in the USA or Western Europe. That restriction was removed but their performance is still questionable (read do not fly them).
excellent video except the AI part. It's terrible, please just use the text and leave out thos terrible AI sound
Life is uncertain. God bless their souls.
May they be in paradise with God almighty
@johnnorth9355
That is true, but the reason those souls lost their lives on board that plane was because dozens of people failed to do their jobs properly for decades. What a disgrace.
Never watch these videos before flying.
Me neither.
fr, I took a month break before flying for the first time in a year but i'm slowly starting to watch them again... I can't stay away 😅
Probably the most terrifying airline accident. Just plunging towards ocean from 35,000 feet with no absolute hope. I hope all the souls onboard passed out quickly so they didn't feel terror or pain.
Flying during world War two was also I think very stressful and full of anxiety. If you flew during that time you were actively targeted and hunted in the sky. And plenty of people still flew and probably many of these kinds of accidents also happened during that time
Doubt I ever want to be in a plane and hear -terrain terrain… pull up 😳😳
You won't ever hear it of course - unless you are in the cockpit. Apart from a case of an aircraft going down vertically like here, the warning itself is not the catastrophe: the aircraft may be working completely well, it just indicates that desaster is close unless immediate action is taken - especially with a fully able aircraft to prevent CFIT (=controlled flight into terrain).
If an aircraft is intact and some navigational error occured to get it too close to terrain: The MentourPilot YT channel has a demo of a terrain escape maneuver, demonstrated by an airline pilot.

The Aircraft in the video is not the one which disintegrated and crashed into the ocean. The plane was a Boeing 747-200, not a 747-400
That is likely the reason he stated that the aircraft was not the same model as shown at the beginning.
Well he could have taken the 747-200 model and merged it with the PMDG 747

About 15 to 20 years ago I often flew on Chin AL from San Francisco to Tai Pei on my way to and from Saigon.
They had an older 747 that always vibrated badly when taking off from SFO. I always like the crews and the great service, but had serious doubts about that particular 747.
Not sure if it was the same one or not.
what a joy to live in one of those buildings where planes fly 100 feet above you constantly. praying this isnt the bad day.
My friends used to live under the flight path of the San Diego landing strip. You eventually block it out. San Diego's also a notoriously tricky landing.
You should watch the videos on here of these big planes landing at Kai Tak. The crab turn to get in there is quite the scene
I live under a flight take off pattern and I frequently am reminded of my concern. Watching THC videos does not help.
You could clearly see the nicotine stains from smoking inside the cabin, running down the length of the doubler plate and surrounding area. This indicaties that the cabin was leaking pressurized air through the damage in that area.
Imagine being the people in the back of the plane when that separated.
A very similar thing happened to a Japan Air Lines Boeing 747SR, flight 123. This particular crash was due to an improper repair on the rear pressure bulkhead after a bad tail-strike. The pilots fought valiantly to control the plane, but the plane was just too far gone, with no hydraulics. It remains one of the worst single plane air disasters of all time.

I am always worried when people don’t know what they don’t know.
Rest in peace 🙏 to all the victims. Thank you very much, for a most interesting video. 😊
If there is one thing that China Airlines Flight 611 and Japan Airlines Flight 123 taught aviation, it is this: DO YOUR DAMN REPAIRS CORRECTLY!
Imagine being the first row in the tail piece that broke off. Nothing between you and the world at that height
Wow thats just terribly sad :( i cant imagine how they felt at the end ..beyond comprehension ..because of someones botched repairs..and someone who passed them as ok ..god bless those whos lives they took.. and hopefully whoever was responsible got a return of Karma !!
I don't think that anyone involved with this repair understood their mistake. Just my opinion.
if u check out the other comments too@@deepthinker999 ...evidence shows a chief engineer it seems from Boeing wasnt consulted ?..so if they had been maybe this could have been prevented ?..we will never know sadly :(
I've flew over 20 747-400 segments on China Airlines in the early 2000s and just finished a B777 trip to Thailand on them in May... This was a bad one...
These types of videos are always so disheartening. The amount of times when the disaster was actually something unavoidable or unpreventable is very, very, VERY low. Most videos like this I've seen it's usually design flaws or cheap maintenance work, because fixing those flaws/doing proper maintenance would be more expensive to the airline company than having to pay the families of the victims a few million of compensation in case something happens...
The plane shown in the video is a 747-400, the plane in reality was a 747-200.
RIP
To the passengers and crew of China Airlines Flight 611
I saw this on Air Crash Investigations: The episode is called Scratching the Surface. How the 💩 maintenance lasted for 20+ years is a miracle!
If I was a pilot and did my walk around and saw the corrosion and scratches on the outside of that doubler plate I would have refused to fly that plane. Fire me all you want, I'm not flying it, and I'd also be looking at the repair and inspection manifests, I'd tell the company if they didn't repair it properly according to the mfr, I'd go public about it. At least nobody would have died and I'd fly another day.
Just one more reason for pilots to take inspections like this seriously.
You should see the record of commercial trucking. Companies struggling to stay in business overlooking maintenance that they cannot afford.
@@deepthinker999 Oh I have no doubt about that. Up to the driver to risk driving those rigs, there are plenty of companies out there to drive for. Find a better one.
If this plane was retired earlier, this accident would have never happened.
Just stunning that after JAL 123 there wasn't a Notice to all 747 users warning them about improper repairs after tailstrikes. Anyone in aviation (or who watches The Flight Channel) knows if it happened once, it WILL happen again.
Originally, China Airlines used a 747-400 B-18272 scheduled to make flight CI611 that day, it was not a B-18255, but because the 744 was serving another flight, china Airlines used 747-200 to exploit it. if the CAL sells to a person who specializes in dismantling the plane, it will not affect China Airlines
If they used the 747-400, this wouldn't have happened. And the 747-400 is more modern too.
It's crazy that pilots have nothing equivalent to rearview mirrors. If the tail or wings fall off, they can only go by sensors (which may not be working).
Sadly, many accidents could have been avoided had maintenance followed instructions from the OEM instead of making up their own rules.
I am certain it was a 200 model sold to Thai Orient and was on one of its last flights.
A colleague in HK aunty was on the doomed flight and was found.
It's very sad full incident my all sympathise with all affected families
The suggested repairs for this, as depicted, leaves me wondering...irregardless of the material of the patch...
what is the required overlap of existing and the patch material. That is actually quite important.
Cyclic fatigue stress. Fatigue stress is caused by cycling a stress on the member, similar to bending a paper clip back and forth until it breaks. The stress on good material without any stress risers like scratches will normally not fail as long as the cycling stress is less than 50% of its tensile yield stress. Anything above that and the member has a definite life span, the length of which depends on the material, the value of the stress and the frequency of the oscillating stress. However, the root of a scratch, steps in the material, or some other sort of crack inititiator (chemical stress corrosion, strain hardening, or just simple corrosion) can increase the unit stress beyond its yield stress without any obvious red flags if not inspected with sophisticated instruments, e.g. x-ray, ultra-sound, etc.
Stress risers are discontinuities either in the surface of a material, at a machining corner such as a step in a shaft diameter, or dislocations of the crystal structure structure by cold working (strain hardening) or chemical stress corrosion. These kinds of discontinuities are present in most machined or cast metal parts. That is why engineers use a safety factor by designing the parts larger than the theoretical. However, in severe conditions described above, microscopic surface or internal cracks cause a " stress riser" condition and the stress is enough to start the crack propagating through the material until there is not enough metal to support the load and the crack propagates through the entire material causing a failure or complete fracture. This apparently what happened here with skin being damaged and weakened, then subject to a cyclic stress everytime the outside air pressure changed with respect to the internal pressure.😢
Amazing how similar to JAL flight 123 this was. Both were caused by an improperly repaired tail strike that lead to metal fatigue and explosive decompression..
