Partnair Flight 394 was a chartered flight which crashed on 8 September 1989 off the coast of Denmark, 18 km (11 mi) north of Hirtshals. All 50 passengers and 5 crew members on board the aircraft died, and it is the deadliest aviation disaster in Denmark. The crash was caused by use of counterfeit aircraft parts in repairs and maintenance.

okay, but can we talk about how incredible the investigators did with discovering all of this data? they did an amazing job narrowing down the cause of the crash and the exact details that contributed to the accident. may all who perished rest in paradise.
Just Saph, I was looking for this comment. Very impressive investigation!
@@drkatel Don't be silly--NOBODY does that on TH-cam. I mean look to see if someone else has posted a comment before posting your own saying the same thing. Surely you've noticed how a simple misspelling can bring 25 or 30 identical comments pointing it out, each poster rushing to achieve immortality by getting their name in the comments section. Thank you for not following this practice--what a much more rewarding experience TH-cam would be if others did the same thing!

I honestly believe this is one of the most important accidents in aviation history. It shon a light on a serious underbelly of the spare parts industry and has probably saved millions of lives since.
@@bigballz4u ALL of the airplanes, everywhere now have to wonder if any of the parts they've used over the decades have been fakes, the cost to dig into every single potential part on every plane is astronomical, not to mention any of the structures that might get destroyed when an accident happens due to these fake parts. And that's not even counting the lives both in and out of the planes that would be killed or injured. There is no way to calculate the true cost of slipping in fake parts unseen. The penalty for making, selling, promoting, offering and using fake parts ought to reflect these facts. It is tantamount to murder.
Ian Chameleon I think it saved billions of lives.
@@rigged4red153 It was certainly a very important discovery, but Ian Chameleon is right. There's no way it could've saved millions of lives, almost nobody would continue flying if it was anywhere remotely near that dangerous.
@@MendTheWorld Maybe even trillions!
Companies don't care about lives.. It all about money, it will never stop..after market parts
This video answers many questions for me. I was a mechanic on CV-580 aircraft from 1967 until about 1982. When I heard that this crash had been attributed to structural failure I was skeptical. I have never worked on an airplane tougher than the 580, and I never saw any corrosion or fatigue problems on the airplane that were not easily corrected before any harm was done. Now that I know that counterfeit parts and poor maintenance practices were involved, I can finally understand what brought this airplane down. Those bogus parts dealers are murderers.
Ex structural mechanic and aviation mechanical fitter IAF. We meticulously inspected not only each structural repair but the adjacent area for FOD and any other possible problems over and over before signing off on a job. Our phantoms were in tiptop condition, we took so much pride in our work. Using fake substandard parts is just beyond comprehension.
Having worked in the legal field for 22 years, my 10 bucks says that maybe a few of those fake parts dealers can be traced back to China.
@Rich H No way !! You mean to say China actually counterfeit, steal, lie, falsify documentation and are all round scoundrels ? I never would have believed !
@@WeGoWalk We (maintenance) were aware of the existence of bogus parts at least thirty years ago. The origins were domestic.
@@WeGoWalk This accident happened in 1989. China was just starting to make T-shirts and socks back then. It had nothing to do with this accident or the counterfeit rings back then.
When it said "pilots are best friends and both were going to retire." I knew. So sad.
I know, so sad:(
@rob hooper the positive is that their unfortunate deaths lead to the arrest of frauds and criminals endangering lives. That's it.
@rob hooper What!? I know you're joking. lol
The only thing more chilling than a "prize flight" is a "children's special". These can't represent anything but a tiny percentage of all flights, yet several noteworthy crashes have occurred on such flights.
rob hooper You are correct. In the US retired pilots die at an average age of 66. So by checking out a little early the men received fame and their families were financially compensated to be better off. I think people should see the glass as half full.
Thank you for a great vlog of this tragic accident. I saw this plane take off. It dep on rwy 19 at FBU. One hour later I saw on the news that the plane was missing. One of the FA on board had lost her sister in the PA103 accident 9 months before. The two pilots had bought tickets to fly around the world, also to fly on the Concorde. The CEO and the top brass of WWL had taken the red eye to HAM to meet and greet the party. They were all in chock of course. 15 yrs later my sister got a job at WWL and she told me the her boss and dir of PR attended all 50 funerals. May the all rest in piece.
Geez, counterfeit parts.... and this accident was 6 years before Ebay.
It must be very difficult to control quality now with the amount of fake and 2nd hand stuff being peddled as new. I've been caught out more than once with electronic components.
@@greenpedal370 that's why you buy from the manufacturer
@@greenpedal370- Then there are the spy chips concealed on motherboards. Concealed in plain sight disguised as other parts, or hidden inside the cases of chips.
@@algrayson8965 You are correct, there are. Perhaps more modern equipment is less susceptible to fraud.
Engines sound like lawn mower engines.
My father was participant to several aircraft wreck investigations; the stuff he had to say about counterfeit parts does not bear repeating in polite company.
Suffice to say, it was blistering.
Laird Cummings
A very sobering and frightening thought.
I was in the airline business for decades as an independent technical representative to Boeing and Douglas, and had my own provisioning service for the airlines I served. As policy, I would never consider any part other than "manufacturer new" in any potentially critical assemblies, systems or applications. FAA 8130 tags with complete traceability were standard and expected. To think anybody would provide a fake or counterfeit part to an operator for inclusion into an aircraft carrying people is frankly unthinkable.
@@alexp3752 Lots of sociopaths in this world :(
I don't blame him.
That was one of the most fascinating, and angering, accident analyses I've ever seen. Even old aviation buffs can learn from this one.
Yes. They should jail those responsible and throw away the key. Let thos who were responsible rot their lives away. Stinger words come to mind but do not want to write here.
Jane I was about to say that! Alaska Airlines 261 was just basically massacre
You should look at the accident report, especially the pictures of the deformed parts. They show an elevator tube with scratches all over it and metal plates with holes deformed beyond recognition. Scary stuff.
This accident was featured on one of the air disaster shows here. It left open the question of whether the F-16 actually was the straw that broke the camel's back in this accident (prob not, but who knows?). Counterfeit parts... whoever made them and sold them should get life for 52 counts of second-degree murder. They killed those 52 people. All for some dollars...
So sad. Nice vid as always, Allec...
F-16 overflying it would not cause that.
I think it was just only a coincidence
Agreed, when watching the F16 part my first thoughts were possible jet wash. It is curious that the aircraft fell right after the F16 flew over.....now with all the fake parts and vibrations I bet it was the last straw....any other aircraft would have shrugged it off but this one was in a world of hurt. RIP to all aboard
💯💯☝
@@jyralnadreth4442 No, as SMB 226B says it was just a coincidence. Two completely random events separate from each other. To destabilize the Partnair flight, the F-16 should have flown less than a meter from it !
Some lottery that turned out to be.
Lottery of death, and chinesium
Reminds me of Christa McAuliffe winning the competition to become the first teacher in space. She died in the Challenger accident while her back-up Barbary Morgan, who came in second, eventually did fly in space.
Deadly
We were all thinking it, I'm glad you said it
In years gone by, I've flown on many Convair 580 airliners. Great planes to fly on for sure! BOGUS parts sold by CRIMINALS..... hopefully these people have been arrested & brought to justice!!!
The fact the same guys had sold parts to the US Airforce for the 747 Airforce One got the FBI interested. The 747 parts came from an Iraqi Airlines 747 blown up in the first Gulf War.
Wow...I agree with the commenter who said the people involved in the dastardly deeds of trafficking bootleg parts should have been held accountable for 52 murders. And who knows, maybe we’ve all flown in an aircraft with these flimsy parts...😳
Very well researched and presented, Allec!
I'm now thinking back to when I was flying with my family from Tampa to Indianapolis and back. Who knows if any of those planes had them.
This is a textbook example of how a specific and statistically ultra-rare “chain of events” has to take place to cause an accident. In this case, the missing link in the chain of destruction happened to be the highly unusual operation of the APU inflight, the broken mounting resulting in a vibration that by itself wouldn’t be an issue. The fact the tail was steadily weakening from the use of counterfeit frame bolts made it possible for the unfathomable combination of factors in that particular flight to result in a catastrophic failure. These are the kinds of scenarios no one can possibly anticipate.
Well done, as usual Allec.
I was a passanger at this plane 10 days before it went down.
It was chartet by brewery Carlsberg for guest by the accomondatioen industry from Stavanger (SVG) in Norway to Copenhagen i Denmanrk.
Chilling feeling cause the return to SVG in the evening, the aircraft would not start, so after some hours, we got an old Caravelle jet to flew us home....
Same operator... only old planes
Nothing wrong with old planes BUT they need to be maintained right & with approved parts.
Great video. It really shows how counterfeit parts can ruin a perfectly working plane.
And imagine the mechanic that changed the bolt, too. Imagine what he had to go through, just doing his job of fixing the plane but accidentally making things worse. He inadvertently brought the natural frequencies of the tail and APU to be practically the same, but how in the world is he supposed to know that? They didn't have equipment to test stuff like that.
I'm from New York, and I've heard of and seen a lot of different fake merchandise, but fake airplane parts is a new one to me. And the most despicable by far. Unbelievable. That's some serious scummy stuff. Those poor people. Half of a company, and 2 veteran pilots a few months from retirement. Anyway, great video brother. I learned something new today, definitely. Thanks for sharing. 👍🏻👍🏻
@AE Schneider Absolutely!
Counterfeit parts are more common than most think. I am a flight attendant and we in Aviation know this. In Miami around the Airport The FAA busted alot of these dealers. They are criminals and murderers playing with our lives.
Having flown the original piston powered (P&W R2800) Convair as a newly hired copilot, 6 years prior, the 8 months as my first left seat assignment, in the doubled horsepower Convair 580, in 1972 was the most pure flying fun of my career, which included those two types, plus the FH227 turboprop and three turbojets. Those powerful GM Allisons, with the hugh four bladed props, were phenomenal on that airframe. It could exceed VMO in level flight with one feathered.
This has to rate as one of the saddest tales. The two pilots, their faultless careers almost at an end, good friends about to retire. The high spirits of the passengers looking ahead to their 'lucky' company outing.
To put into perspective how poweful the Phenomena of resonance is, imagine you’re being pushed by a friend on a swing set. If you’re friend pushed you forward when you were at 75% of your back swing, you’d lose almost all the energy you had in your swing and you’d swing forward, but barely. You’d have to restart your swing.
Now lets say your friend pushed you forward when you were at 100% of your back swing. In other words, you’re at that brief second where it feels like you aren’t moving before you fall back down again into your forward swing. If your friend were to push you at that moment, think of how much higher you will go on your forward swing. This is because the frequency of your swings matches, or “resonates,” with the frequency of your friend’s pushes.
If you have a Left and Right stero speaker at home, switch the polarity of one of the speakers and the output volume is almost zero. That’s because the speakers are outputting sound waves that are 180° out of sync so they cancel. When you connect the polarities correctly, the two sound waves are in sync, they are resonating, and therefore the sound is much louder than “zero.” The speakers are producing sound normally.
Imagine these principles scaled to the size of an airplane which is being subject to tens of thousands of pounds of aerodynamic forces. These poor people didn’t stand a chance.
In the original Air Crash Investigation episode they quoted the ill-fated Tacoma bridge that gave way in 1940 due to the same resonance phenomenon after it shook with the wind. It's called aeroelastic coupling. This bridge was gone with the wind, literally.
@@julosx read an account of harmonic frequently in a ship mid seventies, harmonies were far less understood then, the investigators concluded it had been hit by a wave of the same frequently as the ship and sheared the ship at the waterline, the only survivors were two painters hanging over the side, they said one minute they were way above the sea and next they were swimming for their lives with no warning anything was wrong, even the weather was calm, ships today are compartmentalized to prevent this, it was only the survival of the painters that lead to the conclusion otherwise it would have been a mystery.
Lots of seemingly innocuous design features are there to elimihate/reduce vibration, which, as we have just seen, can be catastrophic. The largest ships have 5 bladed propellers (not 4) to prevent resonance.
I think this is one of your very best videos Allec. Thank you. You continue to do really high quality work
Another moral of the story; do not use counterfeit parts for life and death equipment.
The problem with counterfeit parts with proper paperwork is that they appear legitimate.
Like all the highly flammable cladding used around the world, including Grenfell Tower
Sometimes I worry that we've run out of interesting crash stories and then we get this. Bravo!
Unfortunately we had an A320 go down in Pakistan today.
I would like to see him do Air Indiana flight 216...its the crash that killed the 1977 University of Evansville basketball team.
Would be an interesting one.
@Sir Tristan Being interested in history is not necessarily "cheering for the existence of death and destruction." Whether someone is interested in airplane crashes or not, they happened and unless you have a way of changing history, they will have always have happened. This is similar to how people are interested in other historical events, such as wars, assassinations, or plagues. There are people who even reenact battles; reenacting a battle does not necessarily mean that the reenactors and those who watch them are in favor of death and destruction.
Really interesting. Your animation has always been top class but your written content now matches it. Thanks, Allec!
Although it was a sad ending, I enjoyed watching this video mainly because the visual narration was on screen long enough to read, unlike some. Well done to all the investigators and the many, many hours they put into it.
i remember this scandal. its so sad that peoples greed led directly to the death of others.
More like this please! You really went into the hunt for answers on this one!
Great Video as always Allec👍👍
Great video Allec! Good job on reaching 220,000 subscribers!
Outstanding and thorough presentation as always. Thank you.
What a bloody shame. Kudos to those investigators.
A very thorough investigation, and in the end it may have saved many lives on other flights. Also, a very thorough report by Allec!
ALL of the counterfeiters should face murder charges.
Agreed
As always well done allec!👏💯👍
Allec, again you attracted me to your video. Thank you for your effort in - especially in this case - telling the story behind the story. Great investigation by you and the actual investigators who made the purchasers of the companies aware of faked material for sale. Horrible, parts worth a few dollars caused the crash and subsequently the death of 52 people, leaving their families in pain. This example points out even more, that there´s a reason why airplanes need to be cared very much for and the safety must be worth something. Low-budget flying on the expense of safety threatens lives and the existence of airlines. RIP to all the lost people.
Man those Allison turbines sure sound a lot like wasp 2800s! Lol. Just giving you a hard time. Another great one, thanks for sharing.
Allec, love your work. Keep it coming.
Damn, imagine a plane crash, that blew up an entire market of fake parts.
Imagination not required
@AE Schneider- People can't be educated not to be wicked.
A very very expensive crash.
@AE Schneider I agree with "an educational system that teaches high standards both personally & professionally," but the creation and passing off of these fake airplane parts probably has nothing to do with education, but all to do with greed.
Astonishing investigative work.
Another outstanding piece of work. Great visuals and description.
Some really excellent detective work in this one.
This was a huge problem at the time and several scientific and governmental organizations looked into it. It was beyond the aerospace industry. They found these sub-standard bolts in nuclear plants, submarines, bridges, etc. They were good copies and even had fake company logos, certification marks, and material lot numbers on the head of the bolt.
By far and away the best at this - hats off to you Mr Ibay
That aggravates me as I have discovered counterfeit parts in the automotive repair industry coming out of China.
Back then, those counterfeit parts didn't even come from China. I guess it was thus easier to catch the criminals.
I think I might have a counterfeit oil filter in my car, so I'll avoid driving at 22,000'
When I worked for Rockwell we had a problem with fake imported air brake parts that carried our logo. Air brakes failing on a passenger bus could kill more people than on that plane.
How sad. Irony with the name of the airline “part”NAir
That's not what the Alison 501 D3's sounded like.
Don't forget they were prop jet engines.
For reference, listen to them on the Lockheed L-188 Electra.
I thought the 580’s used Rolls Royce Darts
I shouldn't have watched it then. Such important information.
Guess what, he aliased it with R-1820 or 1830 sounds LOL....
The sound of it hitting the water didn’t sound correct either. Lol
@@abandonedchannel281 RR Rda-10 turboprop engines were used on CV-240 airframes to produce the Convair 600 aircraft. These aircraft were quiet and smooth flying for passengers, but did not not have adequate engine power to carry full loads from high-elevation airports. CV-340 and CV-440 airframes were equipped with Allison 501D13H turboprop engines to produce the larger, more powerful, and more popular Convair 580. The 580 was a reliable, tough, and very capable airplane, but the propeller noise and vibration made the flight experience less pleasant, at least for me.
Very very complex causes of this accident. Whew.
It’s interesting that the old analog data recorder provided them with more information in this case. A digital data recorder would have recorded the flight data without the vibrational interference.
So many things wrong on this flight. I’m terrified of flights but love to watch planes and videos about crashes in the comfort of my room. Stay safe everyone. ❤️😍
Extremely important story. Very well done as usual.
been waiting for this one
Another nice job, Alec!!
Excellent as usual!!
Those people pushing the fake parts should be Hung.
I don't care much about their penis sizes, but I think the people pushing the fake parts should be sentenced to death.
@ Sad ,but true.
@ most likely yes. Who doesn't like getting a deal on something, saving a little money? Be that as it may, they had no reason to suspect that the parts were not authentic, properly manufactured or brand new. So I fail to understand what your point has to do with anything. Were they somehow responsible because they were smart shoppers and fell victim to fraud that most people would never have suspected someone would perpetrate? Are they supposed to feel guilty over that?
Another great video. Thanks.
I would have thought the crew would have noticed the ass end vibrating like a demon?
Friggin’ counterfeit parts - amirite?
Excellent presentation of a sad story. Thank you!
Back in the 80's in CT there were two major Pratt Whitney Aircraft facilities employing thousands. A 3rd company, a subsidiary called Turbine Components opened in Branford and while most everybody were laying off there was a great need for workers. This new facility took used engine compressor and fan blades, inspected them for cracks and welded them. The job paid astronomical wages amid a recession. Unskilled labor including 2 of my family members were hired as welders but for a given period of time because the operation was damaging to the optic nerve. After your stint was complete you could move on to the dept that ground the welds. Not long after, fan blades started shattering in mid air causing catastrophic engine failures. In some cases the vibration caused an engine to vibrate, shear the bolts of the engine pylons ( which I believe were also found to be counterfeit) and engines were simply falling off planes. Eventually Turbine Components laid off most of the hires. Pratt Whitney didn't survive in CT after that. My coworkers and I had a running joke about ducking falling engines but soon conflict with Iran threatened to return the draft and we who hadn't previously served would be inducted. I was in my early 20's and scared to death. Upon a massive investigation things came to light and the counterfeit market collapsed. I believe most every airship was retrofitted.
I absolutely love the work you do. Nice job, very interesting videos. I've been an avid aviation lover for years. Please keep up the great work! Brian, aviation lover and private pilot.
Thank you for that informative and beautifully presented episode. Such a tragedy. Very well explained.
It's hard to read the white letter on some of the video because of background coloring
I know! I actually commented above, one misses half the story!
Hell of an investigation.
Fascinating. Well done. Amazing investigation and results.
Great video. Incredibly sad. RIP all.
Thanks always for well done videos ❤
Nice graphics 🤙🏻
RIP
To the passengers and crew of Partnair Flight 394
Such a sad, preventable tragedy. 😧😠
What a sad ending because of the mechanics putting in bad parts. God Bless the families and sorry for all victims.
Nicely done. That music! 😭
Unable to read against background.
An incredible chain of events and an even more incredible investigation. Those counterfeiters are evil, greedy bastards.
what will passengers feel on those seconds...
I'm Swedish but I've never heard of this accident before. Maybe that's because I wasn't born yet in '89 though.
Anyway, how terribly sad! Rest in paradise, everyone on board.
Excellent video 👌
What was expected to be the reward of a lottery turned out to be a death ticket for the passengers on board that flight....At least it's fitting to know that the pilots, being close friends, died together trying to save their aircraft and its occupants to the very last moment. I also appreciate how the investigators of the crash really put in a hard effort to determine the exact and underlying causes of the crash, and I especially appreciate as to how far they went to crack down those who sold the fake aircraft parts on the black market. Now that's got to take some hard wit. Well done, Allec, keep uploading your well-made and well-thought out videos to educate all who desire to fly safely and to commemorate the victims of all those fatal, horrid crashes. And for all who have watched this, keep in mind to stay safe, and please offer your deepest condolences to the victims who suffered today from the crash of Pakistan Airlines Flight 8303. Keep well, and Happy Memorial Day weekend to all!
Ok, but did they name the ship after the accident at all?
What a shady business at one point. Criminals show up in just about every aspect of life, even when you least expect it. Aircraft bolts!? Incredible.
As soon as i saw that these pilots were due to retire soon, i knew this was going to be a very sad story.
Wow, what an incredible insightful investigation.
Love these
That would be so terrifying to be headed straight down and be unable to do anything but watch the water approach. Does one think about his life, his loved ones, his sins? Maybe in terror, you don’t think about anything.
The authentic (factory) parts manufacturers also should have noted a decrease in demand for their parts....
these are not high volume sales of parts...
Wow, layers and layers deep. Very interesting. And terribly, terribly sad.
I worked aircraft logistics more than 22 years, commercial and military. One ugly addition is reused parts from matching model. Problem with this many are untested or certified for continued use. We, our loggia group held up $2-3 million in parts destined to use pending QA eval. They failed in the QA test lab. Counterfeit parts were discovered being sold through a 3rd party wholesaler who did not validate suppliers. Of course bogus vendors are gone.FBI got involved we never heard anything about it. Procurement policy changed to OEM only or OEM certified by FAA and NIST and OEM.
Have you not done TACA Flight 110? I haven't seen it on your channel but I could be wrong.
How do you make these videos in 19.5/9 aspect ratio?
The counterfeit bolts where overhardened or underhardened?
Wow.....just stunningly sad.
Rest in peace Yngvar Holene (Flight Engineer)
And RIP to all people on board, the crew and the passengers!
The CV-580 didn't require a flight engineer.
Now that was a snowball effect!
The plane was a 580 variant of this aircraft type with Allison turbo prop engines. Seems unusual to miss this fact on this story as Alecs’ recreations are so damn good. Keep them coming either way.
Yes...the plane dated to 1953 but would have started life as a piston engined 340 or 440. Conversions to the 580 began in 1960, with some airframes newly built as 580s.
And when you think people couldn’t be more evil... a black market of counterfeit plane parts????? This can’t be real. Amazing video Allec... what a tragedy.
That's a special kind of greed that makes someone sell fake airplane parts. Money really is the root of all evil.
Pity these criminals weren't planted onto one of these planes with fake parts and flown into the sea.
So scary to think they had got away with such for so long.
That must have been a relief to the fighter pilot. Wasn't his/her fault.
Bottom line....... corruption caused this accident .
Excellent vid Allec.
Greetings from South Africa 👋🇿🇦
How much time did you save not typing eo?
Kuya Allec. One of the more sadder crashes you documented on. I never heard of this particular crash being reported. Winners of a company lottery. Wonder how many "never won anything before"? Sad. A joyous exciting vacation turned tragic for so many families, co-workers, and friends.
Outstanding work as always Kuya Allec. Salamat po
Curios where do you get the music its very relaxing
Just tragic. Isn’t this the same model of plane as the Lynyrd Skynyrd crash, or very similar?
Right on, except some of the band had made comments on the state of both the aircraft and the Alcoholic Pilot. That aircraft was and accident waiting to happen, at the cost of the bands lives.Such a loss.
@@terryofford4977 Aerosmith back then refused to fly on this Convair after they saw the captain boarding the plane holding a whisky bottle in his hand.Now that was wise.
It was a Convair 240 - N55VM.
CV 240
You should read the Norwegian accident report- its plain scary-, almost every entity involved in the maintenance committed gross errors and allowed an improperly maintained and inspected aircraft to leave the ground multiple times, unbelievable. As a matter of point the possible counterfeit parts in the vertical stab attachments were only part of the problem as there was a " home-made" forward apu attachment which had failed sometime before and the apu assy became resonant with the oscillations of the vertical stab which were assumed to have originated from worn rudder hinges ( elevator hinges were worn also, possibly inducing flutter vibrations) in short this thing, In my opinion, was a flying hunk of junk.
