Helios Airways flight 522 - WHAT happened?!

Get awesome Aviation stuff👉🏻 www.amazon.com/shop/mentourpilot
On the 14th Of August 2005 Helios Airways flight 522 took off from Larnaca, Cyprus on a routine flight via Athens to Prague. Due to a combination a of faulty cockpit setup and misidentification of the different cockpit alarms the pilots became unconscious and the aircraft continued it silent flight towards Athens without anyone at the controls.
In this video I will explain the final report and give you my view of the different things that happened on this very tragic flight.

Involving more of your senses sort of forces you to pay proper attention, where a quick glance does not. Maybe it should be considered for pilots.

In flight school I was always taught to call out and point any items or actions, regardless of how mundane it might be. Flying dual, sometimes I would be asked to justify/explain a specific action, even if it was a memory item on a checklist. Even flying solo, I still call out my actions to myself as I do them, as do most others that were trained this way at my school. It helps me to re-assess the situation and consider whether or not what just came out of my mouth makes any sense.

Its a possibility that the pilots prior to going into hypoxia, they may have placed the plane on autopilot. I am really not sure if that was the case. Such an unfortunate incident. Hopefully that the passengers were in a certain stage of hypoxia. Perhaps they were unaware of the circumstances that was happening. Hopefully that was the case. An afterthought, why did not any of the alternative crew, enter the cockpit, to try to rectify that situation. It is so hard to put a positive view on how the crew was acting at that time. They have have also been in a certain level of hypoxia as well.

[@kay9549]

It was on autopilot, going to the set destination, that only an hour and half or so from the airport it had departed from. Since no landing, apparently it went into a holding pattern. This question had been asked, why was any of the crew that was in cabin area early on, why did they not attempt to enter cockpit. Its an unfortunate accident, not sure if they had uploaded any fuel, prior to departing; since it was only one and hour flight to destination.

Years ago someone on a forklift had a fork snap and this resulted in injury or death. Health and safety decided that there had been cracks visible but no one was looking, they were missed and the accident happened. So a mandatory daily check list was issued. The company I was working for took groups of us through the new check. The instructor was going through the list and kept saying don't look too well just give it a token check and tick the box on the list. When it came to checking the wheel nuts we were told that we don't have a torque wrench so don't worry about it. I noticed a gap between one of the nuts and the wheel. I removed the nut by hand and found 2 others loose and gave all 3 to the instructor. I was in the last group. We had over 100 forklift operators and they had all been trained on this particular forklift.

When I did my Emergency Rotation as a doctor my boss always said one thing, ‘think about the life threatening conditions first and make sure it’s not before considering the friendlier ones’.

[@matts4598]

I was thinking the same thing. As a ICU nurse, we’re trained to always first consider the worst case scenario - or acute emergency that could cause what we’re seeing. Like aviation, we have to connect clues from different alarms or equipment plus our general assessment of what we’re seeing. Confirmation bias is another problem that also affects us and can cause us to miss other clues and misunderstand the situation.

True, but that didn't come in the minds of pilots who were already partially hypoxic.

I had a class in aerospace physiology where we went into a room that could be depressurized to simulate air at different altitudes. At "25,000 feet" they had us take off our oxygen masks and do a simple math test. We had the masks off for 2-3 minutes. After a minute, I could not answer the questions correctly and I was writing at a slant. Later, at "35,000 feet", a select few took off their masks. After 30 seconds, their eyes were open, but the were unresponsive. They were told to put their masks back on and one person was fiddling with his, until the instructor rushed over and put it on him. He woke up startled. Based on my experience, nobody, without oxygen, would have been conscious at 34,000 feet for more than a minute.

Indeed. Thank you for sharing this impressive experience.

[@djs2006]

@@NicolaW72 Later in the class, we were exposed to 'explosive decompression'. That consisted of a smaller room connected to the larger room by a hatch in the ceiling. We were in the smaller room and told to keep our mouths open, so as not to hold our breath, and wait for the hatch to be released, then put on the mask. The hatch opened with a bang and immediately the air was foggy as the water in the air had no time to leave. To me, there was no discernible effect to my body. It was actually fun.

When the hatch blew open all the air in the small room evacuated until the two rooms were of equal pressure. I'm not sure of the resulting pressure, but we did need our masks. Experiencing that in an airplane at 25,000 feet would not be reassuring.

[@fraukie1598]

@@djs2006 I think that is the one and only way to prevent such an incident best. I guess they didn't put on their masks because they thought that they could still do it if they identified that this is really the problem and wanted to save the time in case that the problem was another. I studied veterinary medicine and of course we learned about stuff like that as well. Plus I could never be a pilot, because I would turn around to the airport for every little problem and get fired for that pretty quick ;) But even if educated in things like that and extremely cautious about everything if it is not "just" my life at stake. I didn't fully understand what hypoxia does to a brain and how fast until I got in the situation. Last year I got sick (not covid but a bad infection in the lung) and after I was better already and thought it wouldn't be a big deal to go feed the chicken, I made it back into our bedroom, but I sat there and my husband asked me basic stuff like "Are you alright?" and I couldn't even understand the question, let alone answer anything, as he reported I just stared at him, unable to respond in any way. Luckily because of my job I have Oxygen at home (and it was in our bedroom already because during the infection it got a few times pretty bad) and my husband identified the problem pretty quickly. After breathing oxygen for only a few minutes and a few more (it takes a while until enough brain cells are "fed") I went back to normal. A few weeks later I underestimated that I was still in recovery, went to check on the horses and after getting back to bed my blood oxygen fell down to 73% that quick, that one moment I still knew that I have to get the oxygen and call my husband (thank god he was at home), but that was it, when he came in the room I sat on the bed, sunk down, leaned on the wall with the mask in my hand, but no longer able to put it on my face or think enough to know how to open the oxygen valve, the mask could have been a sandwich, I wouldn't have been able to tell the difference. Just like before, I went back to normal (clear thinking and 98% SpO2) in a few minutes after my husband put me on the good stuff :) If one is healthy and the "experiment" is monitored properly it is not really dangerous, so I think every one who has a job where that matters should "try" it once, no book, no lecture can make you grasp WHAT that does to your brain and how quickly every broccoli can think quicker and more logic than you can (if you still know what "thinking" means or what broccoli is). The problem is NOT that a pilot in that situation might not be able to know that he has to put the mask on, it is more like there is not much time until you are unable to know what this "oxygen" might be, let alone what steps you need to take to get it. And if there is no one with enough oxygen in the brain who can help, the point of no return comes really really quick and I think that there are very few people who can understand that without having been there (once is enough, that is something you never forget :))

Ya but, they really sat in their chair for almost 3 hours, using up 3 bottles of supplemental oxygen, while everyone else around them died of oxygen starvation. And not until the final moments, when they clearly felt the aircraft go into the holding pattern obviously, did they decide to investigate what was going on. And they had to have been conscious and alert this entire time because they continued to open the new bottles of oxygen to continue breathing. One would think that after everyone else passed out and they still couldn't make contact with the cockpit, they would realize that the pilots must also be unconscious and investigate. They even had a pilot's license, they could've made contact with flight control hours before the crash, armed with the knowledge that everyone else was unconscious due to lack of oxygen, and at the very least lowered the aircraft to an altitude where breathing is possible. I feel like most people in that situation would have reacted the second they had to crack the supplemental oxygen, and most people therefor could've possibly saved most everyone on board before death or brain injury. Just seems suuuper weird to me, but maybe I'm wrong ¯\_(ツ)_/¯

This is exactly why they warn to put your own oxygen source on fist before helping others, because once the lack of oxygen starts to have it's affects, it's already too late and you won't be able to think clearly enough to secure your own mask. So if they were able to find and use the supplementary oxygen bottles, they were not yet suffering from delerium due to lack of oxygen.

[@BlueUncia]

Of all the air crash stories I've heard so far, somehow this one really gets to me. Maybe it's the way everyone on board was rendered totally helpless, either because they didn't understand the situation as was the case for the pilots, or because they did understand but were powerless to do anything about it, as may have been the case for some of the passengers and the rest of the crew. That last person left awake must have spent hours trying to break into that cockpit, contacting someone on the ground, fighting the controls, you name it, all while knowing that at the end they were probably the last person on that aircraft who wasn't dead or severely brain damaged. And to then have to signal to a fighter pilot (perhaps the first awake person they saw after a long time - so close yet so far away), that you're probably going to die. Absolutely harrowing.

[@TheGuindo]

god i didn't even think about him having to break into the cockpit - i had to scroll back up and check the date to make sure, and yeah, this was after 9/11, so it would've been after the cockpit doors on these planes were reinforced to prevent unauthorized access into the cockpit. i was wondering why it took so long for anybody to try checking in on the cockpit, but that explains it. that's probably just how long it took for him to get through the door.

[@FlorenceSlugcat]

@@TheGuindo not necesarily. It was a flight attendant. The cockpit door has a keypad outside with a code to open it. Usually, on a flight, some of the flight attendants(not necessarily all of them) have the code to open the door. This code exists for safety reasons in case the pilots need assistance or something like that. However, having the code doesnt mean you can enter. When someone enters the code, the pilots are notified by a sound, and there is about a 30 second delay before the door actually unlocks. The pilots can block the door from being unlocked by pressing a button. This ensures that, if a bad person tries to break by forcing the crew to enter code, the pilots can still prevent it from being opened, while still allowing crew to get inside in an emergency(such as if both pilots are incapacited, they will not stop the door from unlocking) Most likely, the crew member entered the code to open the door. I do not think there is any way that the flight attendant could have breached the door while in a hypoxic atmosphere(if you are interested in incidents where crew tries to break into the cockpit, there is an incident where a pilot was locked out of cockpit by the other pilot while the pilot in the cockpit crashed the plane in a mountain intentionally, killing all crew and passengers onboard. The captain could be heard banging and bashing against the door on the cockpit recorder from the moment be figured out he was locked out until the moment the plane crashed into the mountain. Despite his adrenaline and his repeated attempt to breach the door in order to save himself and everyone else onboard, he did not breach the door. Thats a full grown adult male without hypoxia

Helios was a small airline but it was the first time that I saw that special bond amongst the staff in all departments.

Still although Captain went to the wrong train of thought, the biggest problems were really done by the first officer imo. He didn't do the due diligence to check the pressurization is on auto or not. Not one but 3 times. Captain probably thought that since first officer had confirmed thrice already that Pressurization was on auto that there would simply be no issue that end. Confirmation bias really. Of course not denying that his character would have contributed for the CRM related reasons for the crash. Still it's my pedestrian opinion though based on video. You would obviously know better.

It's disturbing that the warning systems weren't greater for something that can cause everyone onboard to die of afyxiation. Should be some kind of massive warning lights and stuff.. so there cannot be any confusion from the start. Just the fact that there are lights and sounds that can mean different things is really dumb. But in the end this is totally a human error - the pilots should have known... first miss checklist, second miss sound alarm, third miss by their superior saying it's the wrong type of warning so they look for something else. What a sad thing.

I wish no country live this tragedy, no man feel this heavy mourn. Dear mentor pilot i really appreciate your analysis and your key remarks as an specialized in aircrafts. I think that this flight changed forever the global aviation code. Ηelios was crashed 40chm outside Athens in a mountain called Grammatikos. In this place has erected a monument in memory of the victims. In this monument there are all the photos of the passengers of the fatal flight. This fact is is really creepy and very very touching. Whole families died in this tragic plain mothers and fathers with their little children. 121 passengers and six members of the crew were lost forever. Omg as i write to you tears are rising up to my eyes. For days and days our televisions were showing the debris of the plain, the rescue crews to try to retrieve the bodies from the debris and the huge fire that the fire Department was trying to quench. Oh i remember the black smoke above the sky of Athens....And the tragic families of victims to scream and cry and their deep pain was and still remains unhealed. Only a few bodies were recognized by their relatives in the hospital and the others were recognized by DNA test. After a few years i remember that at the point of they crash they found a nine years old girl's diary that was inside the only one suitcase that were found intact from the crash. It was a black day in the modern Greek and Cyprian history. Dear Mentor pilot you re so right when you re saying that the analysis and the explanation of such tragic accidents must be investigated in order to explain the mistakes that lead into lose of innocent human lives. You re so right when you're saying that the juman genre must learn from its mistake. That not only minimizes but also prevents the future dangers up in the air and also save many many lives.

This one hits home in an extreme way. I was actually on a beach very close to the airport when this happened and we saw the aircraft on what I’m now assuming was the way down, not having any idea of what was happening of course as planes flew over all the time. The one thing I keep from all your accident investigation videos is what my father, who was a fighter jet pilot in the Hellenic Air Force, told me a long time ago. “Failing to go through checklists thoroughly and with focus will always cause disaster, sooner or later. Always remember, aviation checklists are written in blood”.

[@Spikeypup]

I don't know what is worse, being that flight attendant who is one of only a handful of people alive, having to watch people fade away in the cabin, or being one or the F-16 pilots that must watch helplessly as this plane goes down. Honestly, I feel bad for both but especially that cabin crewmember who, once they finally got access to the cockpit, saw the horror of all the flight crew being out of commission, confirming their worst fears, but as a pilot, having a feeling they have somewhat of a chance to get this under control, and then seeing the F-16's and feeling a little reassured... they strap in, put on their mask and headset, they start to assess the situation....and just when they have their bearings, the left engine dies...they scramble to figure out why and while that happens, the right engine dies... and at that point...they know...they know it's over. So, all they can do is gesture to the other pilots watching from the fighter jets... with a simple finger point, that they are going down. The cabin crewmember gives them a final nod and wave goodbye as they prepare themselves for the final few horrifying minutes of their life. Honestly, this situation is why TAGOUT/LOCKOUT exists in so many fields and industries, if a switch or control is moved away from a nominal setting for maintenance, or if that connected circuit or "thing" is being worked on or is not "functioning as expected/normal" due to a temporary configuration, fault or alteration, it must be tagged with a physical tag (and locked with a lock or device that prevents the control from moving/changing when possible) that details: WHO is working on the item, WHY they are working on it, and WHEN the condition change started and when it should be finished. When the engineer or worker is done, they simply ensure the switch/control is set to the nominal setting or prior setting if that is what is required, test to ensure proper operation of control in all positions (in case they fixed one thing but broke another, etc.), and THEN they can remove the tag. For cases where a tag may not work then a clear but simple mark (like grease pen)/a clip/a cover/etc. is used on the switch/control to Indicate it is marked/tagged and that it has been or may at any time be moved away from its current or its default/nominal/operating position, so that the person servicing the system in question can easily see what they've modified and set it all back when done, as well as so any person coming into the environment can see right away what is not set to "default/nominal/operating" and be made aware that it is modified somehow and needs to be checked again before final sign-off on the job. Again, the worker simply removes the tag/mark/clip/cover/etc. once work is completed and after setting all controls back to the way they found them, the person signing off on the work then verifies that all switches and controls are in the correct position/status. Yes, tagout/lockout is annoying to adhere to sometimes, but again this procedure exists because it is proven to save lives and prevent accidents. Sometimes a switch or control is located tens, hundreds, thousands of meters or even thousands of kilometers away from the element being worked on by the engineer/worker, and this tag is essential to preventing injury or death to them by accidental activation or movement of a switch or control surface, it's a way to say "HEY DON'T TOUCH THIS KNOB/SWITCH/ETC! SOMEONE IS WORKING ON THIS CIRCUIT/ELEMENT! DO NOT ALTER UNDER ANY CIRCUMSTANCES!". I have seen or experienced situations where following the tag procedure has saved lives, and unfortunately, I've also seen where failure to follow this simple procedure has cost lives or caused severe injury and/or damage. So, I must wonder, was this procedure followed by the Engineer, I'm guessing not, because he would have remembered to move the switch back to Auto, or the pilots would have seen the tag and double-checked things better, I would hope. So, I wonder if the airline strictly enforces tagout/lockout or something like it, if they didn't then, I hope they do now. Had they have done it then, this shouldn't have happened, but then again, it was just one failed link in the chain of checklists and routines that caused this accident, it was a cumulation of one failure to follow one procedure/protocol after another by one person after another. No amount of checking and rechecking is too much when lives are at stake... This tragedy could have been stopped by a $0.03 clip or cover used on the switch, a $0.02 tag attached to the switch, or even a simple dob with a grease pen to make it standout and known it was changed... If all three were used I guarantee this would have prevented this tragedy...all it would have taken was $0.10 or less and 20-30 seconds for the engineer to affix the cover/clip to the switch and fill out the tag, attach that to the switch... and done. I don't blame the guy solely; it must have been a culture of bad management and safety as well as oversight and training that contributed to this. Glad that changes and updates were made to the instruments as well as the procedures, so long as those poor people's lives weren't in vain. RIP Pax and Crew of 522...

[@markc2643]

I've got my own "switch in the wrong position" story. I was in ground radio in the Air Force 30+ years ago. I got a call at 2AM that there was no tower recorder indicator in the tower console. The tower recorder and the approach recorder were both in the approach facility. I drove to the approach facility, walked in and found the tower recorder in...(you guessed it)..manual. The approach controllers were only on duty until midnight, and there was a checklist that was done that included checking the recorders when their shift was over. They would have been talking to the tower controllers and going through that checklist. They left the recorder in manual and missed that part of the checklist, and then the tower controllers didn't notice they were missing the recorder light on their console until 2 hours later. I was pissed that I had to wake up at 2AM and go fix their screw up and lose hours of sleep, and I let them know it.

[@realalcibiades2909]

The lack of CRM was probably based on the attitude of the captain; he was an intimidating and unpleasant person to work with, and it’s possible the less experienced crew members just defaulted to him not wanting to interfere with his decisions because he was more experienced and was known for his temper and condescension. They probably assumed he was right because he was so experienced, and they didn’t want a scene. A fatal mistake but one that’s common with superiors that are like him.

That was a superb explanation. The technical stuff combined with the antiquity of this aircraft’s design created the conditions that exposed this crew’s weaknesses. Unfortunately there too many pilots flying who should be doing a different job. I’m talking about the arrogant idiots, the incompetent, the inflexible, those with a personality bypass (and other flaws) and scared pilots. I’ve flown with far too many of these types in both seats. Fortunately they are few in number. I’ll suggest this particular captain was one of those doing the wrong job. I say that not because of what you said but from what two first officers I have flown with told me. They flew several times with this captain and described in detail how he operates. Neither tell a pretty story. My own experience from incident/accident investigation also tells me that there people wholly unsuitable to be anywhere near aircraft. For members of the general public reading my comments may I will tell you that the chance of being flown by two weak pilots being teamed up AND a technical incident occurring pushing this crew beyond their capabilities AND the flight ending unpleasantly is still exceedingly remote.

He jumped since than from one short-time-job to the next one. Obviously and - at least what we know in public - he had huge difficulties with CRM. There was obviously also a huge cultural barrier not only between him and his FO but also between him and his other co-workers in this company.

As someone who has had flight anxiety for twenty years, hearing you talking about these incidents has helped a ton. You're able to give a pilot's perspective, explain why these are such unusual incidents, and describe the kinds of steps that have been taken since then that have been implemented into your own training. I hear you tell these stories and I feel safer to fly with each one. We laypeople often hear about these disasters, but we never hear about how seriously the aviation industry takes each and every one, even the ones that seem like they would never happen again. Other things that have been massively helpful were your descriptions of what's happening during takeoff and landing (the sinking feeling always, always freaked me out) and your summarization of the different types of turbulence.

Yep. I never had flight fright at all, slept through turbulence and landings, but I understand that not knowing how things work can freak some out. My tip is to just ask to sit besides someone experienced and calm who can talk to you, and / or tell the flight attendants, as they watch and appreciate knowing, so they can easier help if trouble / panick. I usually get switched by flight attendands, as I am so ridiculously much taller than everyone else that I think they feel bad for me. I literally don't fit in a standard seat, as my legs would reach through the entire seat and likely touch the person in fron's back a little, if the seat wasnt there. Always have gum, read safety briefings, they aren't all alike, keep windows open on landings and takeoffs. If you need help, just ask people nicely. If you get a bad response, ask someone else. You can meet both nice and terrible people on a plane. I bring headset to listen to music or watch movies, but I used to fly up to twice a month for 6 + years

If that particular switch is very rarely flipped, I am wondering who flipped it, and under what circumstances. I don’t know anything about aviation procedures, so bear with me.... but is it part of landing check or exit procedures (crew previous to this one) to have it in a certain position? Not that this would excuse the oversight of the switch position by the (accident) flight crew, they clearly didn’t do their job. But it seems that switch was in an unusual position, so why was that? It seems to me that when the flight crew leaves their plane, shouldn’t there be a default position for the essential switches?

OK, if "Manual" is not something that should be red lighted, it deferentially should be non-green lighted, because of rare usage.

[@miguelmedeiros4824]

I can't agree more. It should be flashing, perhaps switching between bright green and bright yellow. From a design perspective, people need to critically think, and constantly think "How is this decision going to potentially lead to loss of life". It is very easy for designers to overlook the consequences of their decisions and these issues are hidden in subtleties.

I'm the strange person who during a diversion for low fuel was in panic "omg I'm going to have to endure more extra take-offs than planned idk if I can handle this" while I can explain to everyone around me (freaking out about zomg out of gas) why its actually still safe because there are mandatory fuel minimums to safely divert to a safe place and it actually just means they can't continue to the original destination with enough fuel to double-back to the alternate safely.

[@TruthNerds]

Additional bit of nerdy explanation: Suffocation due to insufficient air pressure (or e.g. breathing inert gases) is _especially_ dangerous because it doesn't trigger your breathing reflex and doesn't give you a feeling of suffocation. That's because these instincts are not governed by the blood oxygen concentration but by the blood carbon dioxide concentration. Exhaling carbon dioxide isn't a problem at all even if the air pressure is very low … actually CO2 dissipates a bit more easily. The hypoxia, on the other hand, is not felt until the brain is already affected by e.g. dizziness and loss of concentration as explained in the video. Which, come to think of it, we are also conditioned to associate with anything other than hypoxia in the absence of a breathing urge… a dangerous combination.
