When you board an airplane, you probably don’t expect it to break in flight. You assume that a certain standard of maintenance has been carried out that would keep the plane you’re flying on in an airworthy state. Airplanes are made of upwards of millions of individual parts. The failure of any one of them could result in outcomes ranging from negligible and un-noticeable, all the way up catastrophic meaning certain fatal injury. When Air Moorea Fight 1121 left for a very short flight in French Polynesia, its occupants certainly couldn’t have been prepared for what would happen to their plane just moments into the flight.

This accident could have been averted using *predictive maintenance* . A computer could calculate the wear and tear on components by measuring forces on cables, turbine temps and other components. For instance, we know that rusted metal has a lower conductivity than new metal. Imagine passing 10V of electricity through critical bolts (ex. rudder, elevator bolts), and when the bolt corrodes, the voltage drops. A current sensor can alert maintenance crew when the voltage drops below a critical level, meaning the bolt has rusted to an unsafe level for normal flight operations. The location of the bolt can be shown as a red dot on the mechanic's tablet, or on a screen inside the cockpit. The only issue with predictive maintenance is when the very sensors that detect the issue break themselves. Monthly sensor calibration would be a must for this concept to work.
Application 1: The left engine of a 9 year old jet has begun to make strange sounds. A vibration sensor in the engine mount sends this information to the flight computer. Temperatures near the ball bearings on the turbine shaft are within the normal range, but are slightly high. Data from the vibration sensor and temperature sensor are compiled, and show that a possible damaged ball bearing may cause an engine failure at 75% thrust, but not 60% thrust. The aircraft computer alerts the pilots and automatically throttles down.
Application 2: A small regional plane is undergoing routine maintenance. A tire tread depth sensor on the landing gear (uses laser measurements) has detected tire wear as the plane's avionics were powered on. The mechanics receive this information on their iPad, and relay this info to the tire manufacturer to order new tires. The sensor says the plane has 1 more month of safe tire operation before replacement, giving enough time for the new tire to be delivered to the hangar.
Application 3: An Embraer aircraft newly delivered to a large airline in 2030 has had the autopilot turn off sporadically during routine flights over the North Atlantic. The flight computer records the time when the autopilot disconnects. At the same time the autopilot disconnected, a false electrical signal of control surface angle was recorded, along with a power surge in the electrical transformer. This data along with the autopilot disconnect warning is sent to Embraer's design team. A few weeks later, the data is correlated with increased solar activity. The cause of the autopilot failing, false data and the power surges in the avionics was from a massive solar storm at high latitudes.
8:46 wearing'em down overtime quote... "the wear on the cable where it failed was due to its chafing on the polamide bush 🎄 located in the cable guide. this wear is singificant:due to the sructure of the 🏨 it had affected all of the strands exept the central strand and had led to the failure or almost total reduction in cross-section of 72 wires out of the 132 that made up the cable"

As someone who's afraid of flying, when I hear "7 minute flight" I think "ah, so I can take a boat then".
EXACTLY!!! I'm with you...
@@sarge6870Boats seem far more sus tbh
@@ElementerChannelmaybe. Still, I can swim a lot better than I can fly.
I don't know what a pilot is supposed to do at 600 ft ASL when he loses control of the horizontal stabiliser. Those people didn't stand chance, may they all RIP.
I don't think he could've done anything, even at 33000 ft 😓
@@MrNicoJac Well that was weird. I type a reply about Sioux City (United Airlines fight 232) and I lost it. They lost the entire hydraulic system when #2 blew a fan blade. Although many were killed, they did make a magnificent effort and almost brought it home. It may be that they Twin Otter's elevator (vertical stabilizer) snaps back into the central position which would be the level flight position (allowing for trim). I just don't know but even a couple of 1000 ft is leaves 0 room for recovery.
@@marcdraco2189 You're right, it may have gone into a phugoid, just like the Sioux City crash and JAL 123. Had the pilot more altitude, the increased speed of the dive could've increased lift, causing it to pitch up until it slows and drops again. Even after that though it would be very hard to land.
I'm no expert and I have no idea if there was something about the twin otter that would make it react differently to those other accidents
Edit: the way the report says the "pitch up cable" kinda implies that the elevator would've been jammed into pitch-down if it snapped, idk 🤷♀️
i just did some research on this and apparently it would have been possible to recover from the LOC and safely land using the pitch trim, which moves the entire horizontal stabiliser - the cable that snapped was only controlling the elevator. however, since he had only a few seconds, and was not trained for sudden loss of pitch control, the pilot can't be expected to think of this and execute in time.
@@Freeeez3 Ah good to know, thanks. Didn't consider trimming the whole stabiliser.
We were anchored off Moorea in a Private Yacht the day this happened. Our crew was the second boat on the scene minutes after the crash. Nothing they could do but tie floatation to some of the bodies.
Several members of the crew and I had flown on that same plane with the same pilot one week prior.
Terrible tragedy. Even excellent equipment needs maintenance.
One comment. You mentioned the pilot had about 3000 hours. If I remember correctly he was a long time extremely well experienced Career Jet Airliner Captain. Air Morea was his retirement job that he took in part for his love of hand flying the aircraft. He was by all accounts a true master aviator. The sort of Pilot you would want to be flying with. But when the cable snapped at 400’ there was nothing for him to work with. He had no controls. It’s also worth noting that only the largest and most modern airliners are entirely hydraulic. Many still use some combination of cable controls assisted by hydraulics, or just straight up cables for some control surfaces. Smaller prop planes are still mostly cable controls.
Hydraulic systems are heavy and these planes just don't have the power or the space to replace all their control cables with them.
Some aircraft use rods for the control surfaces - which is considered more reliable than cables but lighter than hydraulics. I love the feeling they give to the control of an airplane, very firm and immediate. But I can imagine them needing more force with a faster aircraft.
Airplanes have successfully recovered and landed with loss of cables and even hydraulics - but not when you're already as low as 600ft. If the the trim had still worked and there had been enough altitude, they might have saved the airplane and all on it. In fact, not mentioned in the video and what I wonder: why would the aircraft have so violently pitched down if it had been trimmed out properly? There would have been no force at all on the elevator!
All the more reason for strict maintenance protocols in light of the lack of control system redundancy. Intermediate maintenance protocols are expensive. Parts are sparse for older aircraft. Skilled maintenance crews are relatively non existent with many of these smaller carriers. Lots of stress on parts with multiple short hops. Think about it like the wear and tear on a automobile that is mostly used for city driving vs one that primarily travels on freeways.
@@michaelhoffmann2891 I'd imagine a rod that runs the entire length of this aircraft would be prone to bowing from its own weight. Clips to support that rod could result in friction points or even catching as they are worn.
@@dlvox5222 The company running this plane was keeping to a strict maintenance cycle, it's just the lack of jet wash barriers where the plane was parked caused more wear than anyone anticipated.
The report highlights inadequate training for situations like this? Seriously, what training is going to help when you lose all pitch control and nose down at 600 feet?
Pray, maybe
It's one of those "Oh, and while it wouldn't have saved THIS plane, we can't help but notice...'
Gonna bring a comment from another thread over to here.
According to Freeeez3's comment:
"i just did some research on this and apparently it would have been possible to recover from the LOC and safely land using the pitch trim, which moves the entire horizontal stabiliser - the cable that snapped was only controlling the elevator. however, since he had only a few seconds, and was not trained for sudden loss of pitch control, the pilot can't be expected to think of this and execute in time."
I'm no expert, so I can't validate this, but that might be the training they were referring to.
There might also be the matter of maintenance training...
It impresses me how the investigators can look outside the aircraft to determine contributing factors to the incident. Having been fortunate enough to have a holiday in Tahiti I know the people are friendly and peaceful and this would have left a mark on them. Condolences to the families that lost loved ones.
Obviously the staff at the hotel /your accommodation and venues were polite and nice to you, lol. It's a controlled circumstance... And why even act like you studied the social structure cause you went on a holiday... Like you were surprised that the employees weren't rude to your face? Ok... well it's like that everywhere foreign tourists go in any place, including if it were reversed.
What a strange comment lol. "Oh I bet this affected them" as though it wouldn't affect any human being, and I highly doubt most cared unless they were witnesses.
@@bibblybobbly9951 that's the job of an engineer investigator/machine forensic science. .. it's not a job for just anyone.
You speak about the Tahiti people living their like they are little marsupials lol... Left a mark on them? The only concern would be the effect on tourism income.
One of the most underrated channels on RUclips
What a haunting coincidence that you start this episode with a picture of CES flight, thoughts go to those affected by this horrible accident...
I tend to think of myself rather knowledgeable of plane accidents and incidents, and I’m always so pleased when you release a new video on a crash I’ve not heard of, especially these smaller airlines.
There is always the spectacle of a wide body crash and the large loss of life, but smaller incidents like these, with the 21 lives lost, deserve to be learned from as well.
Great vid as always, can’t wait for next week
My favorite thing to wake up to on a Saturday. I’m in Texas and you upload at the perfect time. Thank you DB!
Same here. I haven't even made coffee yet. I love this channel!
Lol it's 10 pm here🤣
Chloe. I have been watching aviation videos on RUclips for years now, whether it be aircraft or travel related and am reasonably familiar with most of the people or groups that produce the. I myself have started to travel quite a bit recently and have even considered joining the fray. Anyways, I just wanted to say that I sincerely appreciate you, your story, your journey and the work that you do and provide so that all of us can benefit from it. Thanks and keep em’ coming. Michael in Hamilton Ontario Canada
Am I the only one surprised that the Twin Otter has no redundancy on such a critical system?
I was thinking the same thing. Redundancy on aircraft should be on all of them. Probably adds extra weight but could save lives.
the cable is redundant in itself. it consists of over 100 strings, and a new cable can take loads roughly 15 times greater than the loads that occur during normal flight.
without the cable getting wrecked by (most likely by multiple) jet blast(s), it would never have failed.
the plane had been severly damaged by external factors (jet blasts), it didn't just randomly fail.
How would that even work? A second cable running parallel would have been subject to the same jet blast-based stressing as the main cable and would have likely been frayed the same.
The fault isn't in the cable, it's in the airport not putting up the jet blast barriers it was supposed to have installed.
The wing are a critical system on a plane… how would the “redundant system” work????
Most aircraft have at least a few single-point-failure systems that do not have redundancy built in. And most smaller aircraft do not have more than one primary cable or push-pull-rod systems to operate their primary flight controls. Having said that, it's conceivable that, had this pilot hand a few thousand feet of altitude at his disposal rather than only a few hundred feet, he may have been able to bring the pitch back under control - and even made a safe landing - using elevator trim and throttle. But at only 400 ft their fates were sealed.
I worked on this very aircraft (serial # 608) as an apprentice about two years prior to this accident. It was undergoing a complete heavy-maintenance rebuild at our facility for the brokerage firm that was selling the aircraft to Air Morea, and this brokerage firm's bean counters were monitoring every expense like a hawk. We gave them a safe airplane of course, and with new engines, cables, instruments, props, etc. just for starters. But the new lubricated carbon-steel control cables we installed were later replaced by Air Morea with stainless cables - which were more corrosion-resistant but not as durable from a wear perspective and therefore required more frequent replacement.
Of course, after the accident the French authorities crawled up every ass at every previous maintenance facility for this plane with a borescope looking for clues. Our AMO was no exception and, not yet knowing the actual cause, we all wondered if maybe an error at our end led to this accident. Not a good feeling.
On a side note, there is another single-point-failure mode on these aircraft that has caused total-loss accidents in the past and has resulted in at least three mods to correct the issue: The flap rods. If one of the main span-wise flap control rods comes apart in flight the flaps on that entire side of the aircraft go out of sych with the other side. This is most likely to happen when flaps are in retraction or extension mode, ie: close to the ground with no chance of recovery once the aircraft rolls. The swaging at the ends of these rods has been modified a few times over the decades to rectify this problem, and regularly-scheduled inspections are carried out for this very reason.
"Given the number of seats of planes which performed such route and the demand..."
I could roughly guess what happened when he said this. If you run a car around that much in a day it's eventually going to breakdown unless maintenance checks was done every day or two. Sad that this happened. :(
(Also was there a boat? Seems like 18km is not that far enough to have a boat to ease the burden on the airplane.)
I’ve flown on this route with this company. There is a boat service between Tahiti and Moorea. But it takes a couple hours to complete. When on vacation you’re in a bit of a hurry to get there, so you fly.
It takes 45m max on their biggest boat but they have an express one which takes 24m now
Anybody else notice how weird the animation is of the lady waving from the terminal you can see from the pilot's - eye view?
All plane disasters are terrible events. I'm a bit surprised that the worn cabling wasn't spotted during routine inspections. I guess it must have been hidden away inside the structure of the plane.
No, there are access panels near the tail and sides where you can eyeball the cable.
@@adotintheshark4848 Thanks for that info as it answers my point/question.
@@nigelh3253 This aircraft like many others have inspection access panels to where the mechanic or Q/C personnel can inspect cables for proper tension, condition, routing, security and lubrication. I suspect these elevator cables or the one in question stretched over time which is not uncommon and started rubbing against a cable guide and started to fray. Over time it was bound to fail. On most aircraft there is usually a Teflon ring around the cable guide to prevent the cable from fraying. I think it went flying many cycles without being inspected and possibly pencil whipped, so sad,,
@@70slandshark47 to quote the invastigation report:
"The failure of the pitch-up cable in the area with 50% wear cannot be explained only by the loads on the elevator control during operations."
"F-OIQI was parked at night with the controls locked."
"An external phenomenon, most likely jet blast, caused the failure of several strands in the worn area."
"The process of cable failure occurred over a short period of time. No signs of fatigue appeared on the failed wires."
when it had been inspected the last time, the cable was probably fine. also:
"When F-OIQI arrived, Air Moorea [...] had not been informed of the installation of stainless steel cables [...]
carbon steel and stainless steel cables being interchangeable, so that the maintenance of F-OIQI was
thus undertaken in the same way as that of the rest of the fleet. [...]"
they should have been informed that the cable was stainless steel, and there should have been a requirement for more frequent inspection of stainless steel cables, since they wear out much quicker than carbon steel. but there was not. and finally, even if it would have been inspected more frequently:
"In fact, this wear is very difficult to detect on an installed cable, especially if one has not previously been confronted with this phenomenon."
@@Freeeez3 Are you saying the jet blast placed undo pressure on the elevator control cables even with the gust locks installed? I have a hard time believing that jet blast is going to place undo pressure on a flight control cables especially when the gust locks or control cables are locked out. I assume the elevator is zeroed out in a level flight position. So the jet blast would be little to negligible pressure on a control cable. Carbon steel or stainless steel aircraft cables are resilient and last a long time when properly maintained. Now I have never worked on a Twin Otter as my background is Commercial Aviation.
Very seldomly did I ever see one or replace one that was frayed and out of limits. I replaced a few that had stretched beyond their limits. But maybe your right that there was undo pressure put on the cables from jet blast,,, and maybe the jet blast was more pressure placed on the cable than what the pilot would normally command.
Spooky intro image given todays sad news.. :(
A literal air bus. I've been on bus routes that are longer than this flight route.
great video as always! love the details and explanation of the cables in this one, it was really helpful to understanding everything!
great episode as ALWAYS, NEVER A DULL MOMENT on D.B. !! and STILL ONE OF MY TOP 5 OR 6 RUclips CHANNELS OF ALL TIME !!!
Always look forward to your videos, always excellent. Appreciate your attention to the little-known aircraft accidents. Thank you very much.
Its funny how you used the Air Seychelles livery for the DHC-6 Twin Otter.
Thank you for a very informative video. Best wishes from Toulouse, France. Home of Airbus.
As always, thank you for the great video!
Thanks for the video. This was an interesting case. I have to say that the lady in the bikini, waving to the planes at the airport, made me chuckle. I'm not sure that's proper PPE, but what do I know about Tahitian ways. :)
I thought that was cool too lol. It makes one think of island vacations! A thought I need right now.
Why does the NPC need PPE?
@@bigballz4u I was just being silly. Her proximity to the plane made me think she was inappropriately dressed, hence PPE.
Hey, at least she was wearing a top. When my wife and went there in '83 it was common to see native gals with one-piece bikinis... if you get my point! Took a LOT of picture that trip! Wonderful scenery, really. Sure has changed a lot in 30+ years.
Why does the NPC need PPE?!
Per 10:25 then, ok, what's the additional training at that altitude? "STEP 1 >> Grab your ankles..."
???
No chance. Great video. 👍
I worked out of KCAE and on the ramp they had speakers mounted so the linemen could hear ground ops. I watched a Cessna 402B freighter take off and immediately started rapid up/down pitching. The pilot began screaming out he had no elevator control as it climbed to 300 ft agl. He managed to make it back around and was using the engines power to go up/down. As the plane entered base, he reduced the power to much, the nose dropped and all both engines at full power did was accelerate the dive. It went in almost vertical into a dense housing area but miraculously hit a empty lot. Investigation found main in Charlotte did not assemble the elev/tail linkage correctly and left a bolt out.
The plane managed to fly a few hours with that issue before failing. Ever since then the crucial tail/elev preflight is something I always 3 check and occasionally ask if/when maint has done any work on a aircraft's rigging. These fail = almost %100 accident. I also saw a aircraft roll over on it's back after the controls were backwards after maint.
Dying because of a small stranded cable that got frayed over time. On the MayDay series, I've seen that even a major airliner has only 3 bolts holding on the vertical stabilizer (and it broke off, killing all on board, after a mechanic used the wrong bolts). I may never fly again.
Thank you for providing the investigation answer for Moorea 1121. It was completely left out of the Smithsonian Channel Aviation Nation video, which showed the crash but then left out completely the follow-up investigation.
Another very informative upload. Thanks Again !! A+
Nice , all the way from Sydney , just watch the addds before I get settled for this new upload
I must of seen this on the flight channel or aleck ibay , but I enjoyed how you put it together
Very interesting and informative. Air Seychelles twin otter's livery in animation brought back fond memories of my time on one of the islands
Great video and recreated aircraft scenes! I flew a Twin Otter for 3 hours. In any plane, I can’t imagine loosing your elevator. Maybe rudder, maybe ailerons or engine/s. But not the elevator; going down😞. May all on this flight RIP.
What? A flight of 10 miles, at 600 feet altitude, 50 times a day! I guess vacationing jetsetters wouldn't consider taking a 30-minute ride on a ferry. After all, you don't want to waste one minute of laying-on-beach-towel time... 😏
3 words, ballistic recovery system
A system such as CAPS could've possibly saved their lives, a twin otter is pretty close to the upper limit in terms of size to be fitted with an airframe parachute system, but that could've probably saved everyone, or at least reduced the impact forces
Thank you!
It sounds like they were trying to make do with a plane too small for the demand, hence so many flights per day. Perhaps the maintenance schedules should include an and / or criteria, so many hours or so many flights.
i just went through the invastigation report, because i was interested how much maintenance had actually been done on the plane, and there were multiple factors coming together here.
the first is that steel cables wear out much more quickly than carbon-steel cables, which wasn't being accounted for.
regardless, the failure of the cable can't be explained by wear alone and the invastigation concluded, that it had to be severely damaged by external factors, most likely (multiple) jet blast(s).
in fact, it would have been entirely possible for a brand new cable to fail under these circumstances - and there are quite a few instances where smaller aircraft were severely damaged due to jet blast from larger airliners.
it was just really unfortunate that in this case, the damage was very well hidden and noone would have noticed it without actually removing and checking the cable.
They had so many flights because it was such a short flight. Iirc, it's a flight of less than 15 minutes.
@Disaster Breakdown Hey there! One suggestion for a future video is West Caribbean Airways Flight 708! Would love a video on it!
Hey. Do you ever sim casually? Or do DB Groupflights?
Tap your brakes after lifting off bruh :) irl you could get very noticable vibrations from the lg wheels turning at high speed freely. :) Also your rudder has some spiking issues, a small null zone around the center should help, that and cleaning the potentiometer on the axis you are using :)
Indeed Tahiti Faa'a is no stranger to large planes, because it's a stopover between Los Angeles and New Zealand for Air New Zealand. I landed and departed there on a ANZ 747 jumbo.
Crazy how another air accident was caused by the stainless steel cable but exactly the opposite reason. The plane in the other accident had this stainless steel cable and the maintenance called forreplacing it back to the high strength NON stainless cable and when the mechanic took the stainless cables out they crossed the new cables and the piliots that were tasked with ferrying the plane back were subjected to TWO HOURS of being in that plane with no control and it crushing them with up to near 5G forces before they just barely figured out how to get a tiny bit of control and actually land the plane. I can't imagine how they were able to keep their head straight enough to figure out how to get control of a plane that was subjecting them to soul crushing g forces and it wasn't just a simple matter of their flight controls being backwards because they were fighting spoilers that automatically are activated and cannot be turned off. Not to mention auto pilot only controlling SOME flight surfaces. Pilots seem to be a very special kind of person with super ability to perform under situations that would deem most people into a puddle of emotions. If you want to look this up it was Air Astana Flight 1388
The flight deck crew was
Captain Vyacheslav Aushev, First officer Bauyrzhan Karasholakov and
First officer in jumpseat Sergey Sokolov
There were also 3 passengers that must have thought they were never going to live to see the next day.
Even when it's not a DC-10 crash, the DC-10 makes a cameo.
Maybe A video Idea about RA97004 This incident is different "The pilots never been given Instruction " It a demonstration flight with high ranking airline buyer of this Aircraft the plane is safe with a system to avoid terrain Instead the aircraft In the incident crashed into a Mountain It shocking if you look it more
10:07: the crash was not investigated by "European Authorities" but by French authorities (the BEA = Bureau d'Enquêtes et d'Analyses). French Territory means French Authorities. There is no European "Transport Safety Board", they are all national since Europe is not a Nation (and will never be ...). The EASA is not an investigation board, it's dealing with regulation, certification or safety protection for EU citizens, things like that.
- Just for fun (not a criticism at all since I think I understand why): the Twin Otter in the animation wears the colours of Air Seychelles ...
"And will never be"
You should contact the authorities, your psychic powers could be put to better use than writting half-interisting comments
Interesting to see someone with knowledge on a specific field such as this one be so driven by his political ideology that he forgoes any scientific or objective rationality he might have had in his dialogue
@@romnix9000 OK. Again, as soon as a comment doesn't go in the direction you wish, you get an agressive reaction. Why do you behave like that? I cannot understand. You could say that you don't agree with me on this or that point (and above all why) and we could even start an interesting discussion. This would be a real dialogue. Nowadays if you don't say what "everybody" is supposed to think you get insulted. What's going on? Mindblowing!
What the hell has my comment something to do with science or "objective rationality"? In your mind rationality is obviously what you think and all the rest is bullshit. Up to you but it's pretentious, to say the least, and that's not the way it works.
I just stated something factual: crash investigations are under national responsibility all over Europe and that's it, like it or not, there is no "European authority" in this field. It was just a clarification, not a criticism, otherwise I would just not watch these videos. You can disagree but that's the way it is.
Now I don't know but maybe your dream is something like a "European Safety Board" equivalent to the NTSB, in the frame of some kind of "United States of Europe": ok, fine but that's precisely ideology since first it doesn't exist and second this idea is not even being shared by everybody. In my view, this will never happen for cultural and technical reasons, among others, but you can have a different opinion and I will be respectful enough to not tell you that you are an idiot "driven by his political ideology". Do you understand what I mean?
So I would appreciate you moderate your words and take a step back before writing a comment and the world will be a better place. Have a nice day
Maintenance is one of those things that the average layman seems to not appreciate or really understand.
Neglect maintenance on your car, for example, and at best, it won’t last as long as it should..and at worst it will leave you stranded on the side of the road.
With aircraft, maintenance neglect will at best cause a terrifying mishap, at worse…you get something like this.
Regardless of how “tough” a machine has a reputation has (an airplane, vehicle, boat, ship, refrigerator, firearm, whatever), neglecting maintenance still is not really acceptable. The difference lies in the severity and type of penalty for that neglect.

Could you make a video about Arrow Air Flight APW1285R?
"Arthur, I have a plan. I've finally got us passage to Tahiti. What do you mean? Of course its safe!"
If you ever saw the stabulator attachment point on an otter you probably would never fly in one.
0:06 - If I boarded a plane and saw that much trash on the floor, I would question the airline's corporate attitude concerning rushed aircraft turnarounds. If they don't have time to clean up the messes, what else don't they have time for?
Typically, most aircraft have control locks to prevent the sort of "banging around" that the French DGAC pointed the finger at. I guess the "Twotter" as we call them in the industry does not? In any case, ALL light airplanes use cables to operate the flight controls. None have second backups, since the cables are so utterly reliable that the notion of them breaking is unthinkable. Light planes like Piper Warriors and Cessna 172's have to have a yearly inspection [cost is typically $1000-2500] and the cables get plenty of attention. A frayed cable is a NO NO and must be replaced! Most airlines outside of Russia use a repetitive maintenance schedule that has certain and different sections of the plane examined every 100 hours in order to prevent this sort of problem. I am very surprised that the problem with this plane's cables wasn't caught in time.
The report states that there was no visible external wear on the cables. Which makes sense, because the elevators were always locked when the plane was parked when not in use. The problem was the stress put on the locked cable by the jet blasts while parked.
@@Uldihaa That still seems a bit odd. Thanx!
You never assume an aircraft is airworthy when you buy it. That's what inspections are for. I bought a plane fresh out of annual but it was a paper annual and I had gear failure in the first hour I flew it. Never assume anything when it comes to aircraft
I love your videos please do more. Also i already asked a while ago could you make a video about West Carribean Airways flight 708?
I'm sorry, this event is tragic and I shouldn't find this funny, but the phrase "The captain was heard on the cockpit voice recording giving a verbal indication that he knew something was immediately wrong." is an amazing euphemism for what he probably said. It's on the level with that nuclear power plant fire where the accident report said something like "attempts at putting out the fire by repeatedly hitting it with a flashlight proved ultimately unsuccessful" and you can just see the absolute panic behind that incredibly formal description.
Was there anythibng at all that the Captain could hacve done, for example using power to reduce the impact of the crash? You said there was not much that could have been done, but was there anything?
No because the plane didn't have any redundancy besides the cable system.
Also considering the altitude of just 400ft the Captain probably had like 10-20seconds between the failure and the crash. So no not really
The situation was survivable. He could have added power to pitch the nose up while using elevator trim to level flight. It has been done before.
@@tombloom99 not if the cable broke for the tail controls.
@@wyomingadventures There are two cables, one up one down. The trim is a separate cable or servo.
What type of training, glide?
Something wrong if private pilots in their cessnas need an annual maintenance inspection that would detect and replace worn cables, yet this commercial passenger aircraft apparently didn't.
please do a video on the plane that crashed into the alps that had a rugby team on it
The women at 3:57 was so happy to not be onboard of that old plane in her bikini
any danger of an update to find out how many planes /lives were saved when inspections of these cables were mandated to be more frequent?
10 miles? I would have gone by boat.
I really hate airlines that do this. There are no FAA inspectors anymore they leave it up tp the airlines to take care of their planes. In the tropics you really have to check planes because of the salt air and humid conditions.
Good stuff! Someone donate some modern stuff so this person can use the latest flight sims for their content.
Does anyone know where Disaster Breakdown is from (sorry not sure of his name), he has an interesting accent which makes it hard to determine where he could be from 🤔.
Just curious. Love these videos too, very informative.
*She is from the UK. I say she, because she's transgender.

@@robertmcghintheorca49 oh right my bad didn't know she was trans
still tho where in Uk is she from?
Depending on where on earth I'm flying... no. I don't expect these things.
Superbly researched video as always- btw Moorea is pronounced "Moh- Oh- Raya" not "Mooh-reea"
Everyone pronounces words differently. I have a couple names from my state people pronounce differently. Grand Teton. Dubois. Gros Venture. We just laugh but know what they are talking about. Like Teton. So many people get that one wrong. All pronounced the French way not the spelling of the word.
@@wyomingadventures it's a Tahitian word, and there's just that one pronunciation for the word. We can get away with butchering loan words and loan names introduced into English, but you start stepping outside of "they know what we're talking about" and into "what if I'm accidentally saying something profane or nonsensical" territory. When someone lets you know how to pronounce a foreign word correctly, it's a good habit to learn to say "thank you for updating me" or "thanks for letting me know" and then start using that pronunciation.
Sounds like it should be spelled Mo'orea, kind of like Hawai'i, to get people to say it right.
3:42 …and more than 75,000 landings…
the only thing the pilot couldve tried is add flaps to cushion the decent
3:54 wtf
Poor pilot, theres nothing he could have done. Must be among the worst pilots nightmare to loose such critical fonction of the plane.
Why is that lady doing nothing there? 3:55
The true heroes of aviation are those people who seldom get a mention, the maintainers, if it weren't for them, there would be no flying.
Please do China Eastern Airlines Flight 5735 Next please...
The final report hasn’t came out yet
hi DB
Predictable, preventable. Pick your carriers wisely.
Tail fin. Lol
Next episode
Can you do about the Silk Air case(A suicide incident) or even about the MH17
He already did on SilkAir Flight 185 2 years ago. That video also mentions about Egyptair Flight 990.
@@sunnyfon9065 Oh I realized that he made it already
Sorry my bad
I guessed it
3:56 look at the naked woman
You sir are wrong. I expect every plane I'm on to break in flight. The fact that it hasn't happened just means it's probably more likely next time.
I don’t think you understand probability
A sailor or marine engineer could have prevented this. Stainless steel cables are prone to crevice corrosion. Galvanized cables corrode from the outside, so a visual inspection will reveal it. S/S cables corrode on the inside due to salt and the absence of air/oxygen, so need to be replaced more frequently.
This occasion has nothing to do with corrosion other than the manufacturer recommending the original cables be changed to stainless steel to avoid corrosion. The video has to do with chaffing from the cables constantly rubbing on parts around it.
I've sent this already, but it didn't show up, so I will repeat. Sorry it's important. This tragic accident could have been prevented by normal flying skills. Here is a part of the Twin Otter flight manual. It's not just that the pilot did not read the manual, it should have been instinctive airmanship. Trimming a plane is something that the pilot does dozens of times on every flight.
From the AFM:
Elevator Control Malfunction
WARNING
AIRCRAFT LONGITUDINAL RESPONSE TO ELEVATOR TRIM CONTROL AND POWER CHANGES WILL BE REDUCED. AVOID LARGE AND/OR RAPID CHANGES IN TRIM AND POWER.
SECTION 3 EMERGENCY AND ABNORMAL PROCEDURES
TC Approved
If movement of the control column does not produce a corresponding change in pitch attitude, longitudinal control can be managed by using the elevator trim. Engine power should be used to control vertical speed and airspeed.
Flaps should be extended or retracted cautiously, in increments of 5° or less.
Application of power will usually result in a nose-up pitching moment, and reduction of power will usually result in a nose-down pitching moment.
Extension of flap will usually result in a nose-up pitching moment, and retraction of flap will usually result in a nose-down pitching moment.
This crash should have been an incident. Every pilot without an autopilot can fly a plane with elevator trim.
Another armchair boffin not understanding the difference between sitting on a comfy sofa and thinking about something, and being faced with an 11 second window to diagnose, fix and fly out folowing a shock. Even in pre-warned exercises it takes 4-5 seconds to affect a trim and time for the plane to respond. He was too low and had too little time when the cable snapped. You are deluded if you think this was something you could have handled.
@@mehashi I explained this. Add power and the nose goes up. Add up trim and the nose goes up. The trim button is right there on the yoke. Both are independent of the elevator cable. I have 1500 hours in 10 different planes. Very basic planes, but not quite armchair.
@@tombloom99 After 1000 hrs you still don't seem to understand that in times of crisis humans freeze, and the plane takes time to respond to inputs? In 11 seconds you would also unfortunately hit the floor like a sack of potatoes. It's not a lack of theoretical knowledge you are overlooking, it is the reality of the situation. Sudden failure with insufficient airspeed or altitude. You seem to forget that powering out of a dive requires height to complete the maneuver? And adding trim takes time? Neither of which he had. And you are the only human who doesnt suffer a shock response?
Sometimes we really are in a no win situation. It's so horrible that this could have been prevented by routine maintenance.
@@mehashi I quoted the Twin Otter flight manual above. It explains how to deal with the problem. It does not say 'you're gonna die!'. The control inputs are almost instantaneous and should be instinctive.
@@tombloom99 "It explains how to deal with the problem." *assuming a number of factors that sadly weren't met in this particular situation*.
Do you assume that all maneuvers that succeed at 5000ft at cruise, would also result in success at 1000ft at climbing speed? You are focusing on the written word completely devoid of the context of the situation.
Please the story with Cathay Pacific flight 780.
3:48 Woman in bikini waving 👋🏾 🤣😂🤣😂

Whut
03:59 Why is there a girl in a skimpy bikini waving at the plane? XD
You should rename this video to "The Terrifying Case of more ads than video."
French and airplanes should never mix. If the captain is French, for safety purpose, disembark immediately
Synopsis
Probable causes
1. Poor maintenance
2.Pilot error
Amicable solution
1. Pilots should take a desk job after retirement
2.Engineers and Air traffic Controllers too.
A time for Everything indeed.
Upon reaching retirement age all Employees should take a desk job and allow for the younger generation to enter the workforce.
This will decrease the unemployment rate and will allow our next generation to continue the legacy of hard work.
Read the Book of Ecclesisastes.
And except for #1...what does your speech have to do with the video?????
@@sarge6870 As it is written there is a time for everything.
A time to be born and a time to die.
A time to work and time to Rest.
This is what a plan some faith and moneee gets you
Stop calling people by their last names. Call them by their first names. It was a accidentally accidental accident.
