How A Piece Of Tape Led To This Plane Crash (Aeroperu Flight 603) - DISASTER BREAKDOWN

[@DisasterBreakdown]

CORRECTION NOTICE kzbin.info/www/bejne/pXmVnXmBl7unmJI&ab_channel=DisasterBreakdown it has been brought to my attention that I have made an error in this video with regards as to which part of the aircraft was taped over. In this video I used the terms "Pitot Tube" and "Pitot Static Port" interchangeably. Though part of the same system, they are different components and it was the Static Ports which were covered. This is a rather annoying mistake which I failed to pick up on. Thank you to those who pointed it out. If you found this video interesting be sure to subscribe as there is a new video every Saturday.

It a shame that you have portrayed this as a pitot problem and therefore compare with Birgenair, as there in reality except for the type and that both crashed into the sea is no comparison at to be made at all. It is even more of a shame that you like all others who have portrayed (copied) this accident show this aircraft flying at night with the lights and coast of Lima visible. You have obviously used the accident report for research, so I can not understand how you could have missed the weather (cloudy and 6 km vis) and the fact that the tower saw the aircraft entering the clouds (after windshear warning) before the departure end of the runway. This alleviates all the "why didnt they just turn around and land" comments and allows focus to be on the predicaments this crew faced. In my opinion you should redo this presentation (and leave out the airbus cockpit parts as you have a nice B757 sim)

[@jirensan828]

The first officer sounded very bright and a good problem solver. It was an impossible situation but the first officer's intuitions seemed right.

[@leothefirst]

Throughout the emergency he did indeed seem to make better judgment calls on the conflicting information the crew was presented with. It is unfortunate that they didn't act according to the FO's intuition. I can only imagine how disorientating such a situation must be, but I rather overspeed than stall the aircraft and it seems that was what the FO thought too. But ultimately they were presented with an impossible situation (quite possibly one of the hardest situations a pilot could ever face, no flight instruments and no outside references). I think the likelihood of a different outcome was quite low.

[@bluejay7058]

@@leothefirst I fully agree. There's plenty of audio feedback if you are indeed overspeeding, but stalling is a silent killer. It's better to ease up when you hear the plane creak than to believe that you aren't falling.

The captain doomed them from the get-go. As soon as they took off and the altimeter weren't operational, he should have made the decision there and then to return.

Stick shaker or no stick shaker, the call for a plane to come guide them should be a no brainer. I dont get, why the captain was against it. They had lost all functional instruments, they didnt know their altitude, their air speed, nothing, and its pitch black outside with zero visual references.

@@borisgetman9222 i agree this is something that should be allowed to happen in every field, not just medical. the fact that there IS judgement at all does no one justice. especially in professions where you are literally taking a life into your hands, getting a firm double check and/or assessing a mistake in action is critical. in this video's situation, even if the pilot didnt want help, even mentioning the faulty equipment, he should have been humbled and allowed his F/O to complete his call for assistance. such a tragedy this happened. im also pursuing a medical based field, and its important that all the i's are dotted and t's crossed, even if that means having someone double check that simple math problem for dosing. im happy to hear there is at least one medical professional out there putting ego aside and ensuring the health and safety of their patients :)

She said that the last thing that she knew about him was that that he suffered from depression after his brother’s passing and never worked again for that airline.

[@tahustvedt]

The too low alert should have been a huge warning as that doesn't come from the pitot/static. It's from radalt. The controller saying they were 9700 feet up caused them to also distrust their radalt.

[@reidleblanc3140]

they had no way of knowing the problem was with their pitot things though; reasonable enough to get suspicious of all their readings when for all they knew it could have been a problem with any other step along the way that might also have affected other readings

[@ryjelsum]

@@reidleblanc3140 The GPWS kind of works on its own, doesn't it? Their altimeter and speed readings were wrong, true, but that kind of has no bearing on what the GPWS does. It seemed like the captain wasn't really aware of which systems were producing which warnings, which resulted in him getting extremely confused. The F/O was much more on point, it seemed like he picked out which warnings were out of the ordinary even with the issues they were experiencing.

[@1994TeeJay1994]

@@ryjelsum It seems that the Captain preferred to trust his ATC - not knowing that his plane was feeding the ATC incorrect information. The ATC probably did not know that this was the case too.

[@ryjelsum]

@@1994TeeJay1994 You're right, trusting external information is a better bet in this situation, but again it brings up the issue of the captain not knowing how the systems of the plane that he is flying operate perhaps as well as he should. Maybe the detailed knowledge of what systems feed data into other systems and what systems do their own measurements is more in the realm of a flight engineer, but it feels like a flaw in knowledge.

[@Squirreltasticqueen]

Disclaimer I don't know jack or shit about flying but my instinct is to pull up when the alarm goes off. I imagine fuel issues maybe being a problem until the rescue plane finds them but like Better safe than in the ground/water. Because I don't know much I'm wondering why they didn't. Sure the readings are all jacked up but that's the one that you need to DO something about.

[@powwowken2760]

One of the scariest Cockpit recordings ever released, re-enactments I've seen didn't the situation justice, nor do justice to just how on point the FO really was, he was asking all the right questions and thinking up smart solutions despite his Captain being (understandably) completely lost and also being given junk information by ATC, who didn't seem aware that his tower got their radar altitude data from a planes transponder and not a radar ping, and that's on the training the controller received or didn't receive.

Try the cockpit recording where the autobus was stalling nose up into the ocean without the pilot understanding what was happening the entire time. This was due to the same tubes that were taped over in this video. Instead, the tubes on the autobus was momentarily frozen.

Of the hundreds of air disaster videos I've watched, I've never seen a plane crash because the GPWS was inaccurately activated, but I've seen plenty of crashes where the pilots either didn't take the GPWS seriously enough or simply outright ignored it. Knowing what I know, if I were a pilot and "too low terrain" sounds, I'm immediately increasing power and pulling up no matter what.

[@juanp2k3]

That's exactly right

[@riggs20]

The captain was in absolute denial of the situation. The first mate would've saved them if he was at the controls. He called everything. Jesus that is heartbreaking.

[@LAKD]

Hindsight makes it easy to say the captain was clearly making it worse. You have the bias of knowing what actually was wrong, they had no clue whatsoever and it would be impossible for them to actually make sense of it. They were consistently getting the same faulty data from the ATC, their instruments were clearly not making sense, so why trust any of the alarms anymore without being skeptical? They had no horizon, they were doomed and their only hope was finding a reference point.

[@ernestkovach3305]

Nope.

Why not try to climb to see if the ground alarm stops? This was very simple to do!

Yes this is a very scary situation but if you knew that you were getting faulty speed you can see erratically trying to use VFR techniques and I would have turned back to Lima to use it as a reference. I'm not a pilot and even I know no instruments over the ocean at night is deadly. I'd much rather be over any sort of land to try to find landmarks. But the confusion is understandable. But a lot of mistakes are still made. Instead of stopping and thinking and catching the clues that your being lied to by your speed and altitude and that you should be really listening to is the stick shaker and the ground warning system. Having another plane come up would have also probably been a good idea I don't know why they couldn't have asked the next plane that departed to just go do it immediately.

And that abrupt _cut_ of the recording at the end made me held my breath. In situations such as these, it is required to keep a cool head. The captain was gone, having allowed the warnings and alarms get to him. But the F/O was calling the shots and was at least rectifying the situation with an actual solution by calling an assisting aircraft. All this, in the middle of the night.

[@jmitterii2]

@@SaraU_U The captain seemed to be panicking. No good. Even feign to yourself that everything will be figured out, laugh at the problems... that has helped me when in weird situations that had my heart rate skyrocket. In fact, the moment I laugh at the various predicaments I've gotten myself into, is when the troubleshooting steps came to me. Firstly, they shouldn't have asked ATC for their altitude. And ATC should have known the data was coming from their aircraft that was having altitude instrument malfunctions; and this should have been relayed by ATC reminding them this data is coming form your plane, is likely false information; that the pilots need a visual reference to ascertain their altitude; direct them to some lights on the ground. Secondly, the airplane is still flying. Altitude and altimeter, pitot and pitot static instruments are malfunctioning; something is blocking them. Don't rely on them. Not sure what equipment they had. 96' GPS was limited due to being military use and only scarce civil use at that time. Today, one could just utilize GPS speed and altitude readouts; they're good enough; ground speed and calculated altitude via GPS. Without that, visual references of lights on the ground work. And then wait for a chaser aircraft to help estimate airspeed for landing. They could fly in formation on glide path to landing to provide their airspeed. Everything would have worked out. Freaking out just doesn't help. No need to panic; you're either going to be dead or injured soon, or fine and dandy. Panicking won't alter this fact... but possibly make the former more likely.

[@leothefirst]

I think he seemed so calm because he didn't believe that it was true. Presented with conflicting information he made up his mind about what he thought the aircraft was actually doing and stopped believing any indication that was contrary to his belief.

Never ignore the GPWS!! So many planes that have crashed like this one, the pilots ignored the GPWS. Unfortunately the F/O knew that it wasn’t overspeed and that the stall warning and the too low terrain warning were right. The captain didn’t.

[@BlackDiamondYoutub]

​@kestrels.9189 that's exactly the problem. Often they do do 'something', barely pitching up or putting in a very slight climb because they don't believe their instruments, and that's precisely why they crash. You hear terrain terrain, you go TOGA and pitch up 20 degrees until you stop hearing it. Don't just slightly do something to pretend

[@grandv12]

Really nice video, however the pitot tubes were not obstructed, the static ports were the ones blocked with tape that was the same color as the underbelly of the 757, which was also the reason captain Schreiber did not noticed it during the walkaround.

[@justinwallace390]

Was wondering the same. I thought I had just watched a different documentary that showed it was static ports, not the pitot tubes.

[@thetman0068]

Oh that makes sense. If it were a pitot tube the only affected parameter would be airspeed, which would be noticed on the take off roll and cause an aborted take off.

[@simplyrowen]

The same color as the underbelly 🤦🏻‍♀️ I exercise a higher level of concern when writing something that I don’t want others to miss (on my website, a newsletter I send out, etc) by using a different color on the font; and maintenance couldn’t think of using masking tape of a color that stood out? 😩

[@kevin6293]

I’d like someone to do the crash that led to the 1972 miracle in the Andes. Every documentary focuses on what happened AFTER the crash, but not much to the crash that caused it all. I know a little bit about it. The plane was cheap and had problems generating lift. One of the last planes you would want flying you through the Andes. Heavy cloud cover gave them zero ground visibility, so they had to use their instruments and calculate when the plane had crossed over the range. Somehow they badly miscalculated and thought they cleared the mountains when they were still over the middle of the range, literally. They thought they had traveled twice as far as they really had, which is quite an egregious mistake. Was it an instrumentation problem, pilot error, or both?

Big difference between blocked pitot & blocked static. Blocked pitot would have been caught at the 80 kt speed check on take off. Blocked static would only show up on the climb out.

One might hope that one of the recommendations was to use fluorescent green tape with like two foot trailing ends. And maybe future pitot tubes might be enhanced to have a little hose with which to pressure-test that the tubes are open.

I reckon the F/On would’ve managed that situation alot better. He understood that the shaker stall alert must mean that the altitude readings they were getting were false and needed to increase speed. I also reckon he would’ve made the decision to increase the altitude after the alert. Although it was a very stressful situation I feel the Captain was incompetent in this situation.

[@ByzantineDarkwraith]

Though the stickshaker was probably not working correctly because it depends on indicated airspeed to tell when the airspeed is low enough that you’re risking a stall, it’s definitely still a better bet to believe you’re potentially stalling when you have the engines at idle, a level flight attitude, and the freaking *speedbreaks* out, and so you should increase engine power, retract the speedbreaks, and if it were me I wouldn’t push the nose down if I didn’t know my altitude (unless it actually stalls and starts dropping by itself in which case you’d just have to perform a stall recovery by pushing the nose over and hope to god you have enough altitude). And then after a bit of flying like that, level and at TO/GA power (especially if I had just gotten an EGPWS warning as well), I would fly at around max continuous thrust in a tight holding pattern with a slight nose up attitude until it could be figured out, or another plane could reach me to guide me back to the airport. (Alternatively, I could get vectored back to the airport and ask to be guided only through very low lying areas with the assumption that I may be at only 1000 feet above the ground or so, and then attempt to establish a visual frame of reference by looking at city lights. Also I could decide to trust my radio altimeter and gain a much better appreciation for the situation that way as well)

[@Elias-nj6gi]

@@ByzantineDarkwraith may I ask where you got this information that the stick shaker deoends on indicated airspeed? I always thought the stick shaker depends exclusively on flap position and the angle of attack sensors which measure the direction of airflow. As such, those sensors should not be affected by covered static tubes or pitot tubes. And I don't see a reason why they shouldn't have been working correctly on this flight as well.

[@chistinelane]

I think the main problem here, is that so many vital systems can be disabled, with fatal consequences, so easily. A simple backup altitude sensor would have saved them

[@ByzantineDarkwraith]

They had a backup altitude sensor, it's called a radar altimeter. It's how the GPWS knew how far from the water they were (and it could have also told them how far from the water they were a long way above that as well, had they decided to look at it). So I guess they're saved then... someone should let them know.

[@mrjayjay124]

You make some of the best air disaster content. Love it.

[@jtveg]

It is absolutely inexcusable that the flight crew and ATC did not know that altimeter readings are transmitted to the ATC radar by the plane's transponder via the plane's own instruments. So whatever erroneous reading are in the cockpit are also being sent to the ATC radar. Also the crew should have had enough experience to be able to hear if the engines were at idle or at max revs. So when they set the engines to idle but the IAS was showing that they were accelerating while in level flight (according to the ADI), they should've realised that they in fact weren't. Set the throttles to 71% or cruise thrust and turn back towards the coast so that you can discern the horizon by the city lights. Get vectors to the airport and configure for a high speed landing.

[@789know]

No one will know all the details of how the system work. I doubt most pilots are inform about the attitude of ATC comes from transponder. Some ATC has their own radar that independently read attitudes as well. So it varies depends on system. ATC staffs are not technically staff as well. They are trained to guide aircraft, not knowing the inner working if the system. Also hearing noise is a very inaccurate way to tell thrust and there is a fee second delay between throttle and the thrust of the engine It is very difficult to know the actual attitude since it is inaccurate. Turning back without accurate speed, attitude and gryo data at night is very dangerous, especially if there are also dozens of alarms, sometime contradict each other. They already requested vectors, but missing 2 of the most important equipment is next to useless as you can’t fly. Since you can’t really fly safely. Therefore there is another plane taking off to guide them, but it is too late before it crashed. Hindsight is easy, but in their situations, at night it is difficult, especially if you have no idea what equipment is really working at that time. Even you, when you are using a computer, don’t know all the working of a computer and software, and inner working of programs and hardware, you can’t really says it is inexcusable as you can’t expect a these staff to learn all inner details that sometimes differ from airport to airports

[@789know]

Also turning at night not knowing what other equipment is accurate is extremely dangerous. And without knowing the speed, and having stick shaker and overspeed warning screaming at you at the same time, you don’t really know whether turning will result in a stall as heavy planes can’t really turn that much and the equipment is not really useful and not know which of the other equipment is potentials faulty. Also there is mountain nearby, without attitude information, at night, you may risk flying into the mountains, unless you expect the pilot to be geologist where he can tell where the mountain is at night with only a few city light while still need to solve the problem

[@jmitterii2]

@@789know As far as US regulations and aviation and ICAO rules, civilian ATC does not have any means of altitude scanning. It's custom So both pilots and controllers should have known where the data was coming from: the aircraft. Only military radar systems provide altitude estimates of targets for intercepting and surveillance purposes. It's also why Mode C or S with altimeter encoding is required in the US in airspace A, B, and C and where ever other as indicated on a FAA map unless prior clearance before flying through airspace with that controlling agency per 14 CFR § 91.215 It's common custom on initial contact with controllers as a pilot to say your altitude. If you don't, they will ask you. It's called altitude verification; controllers must identify and ensure the data your plane provides on their scopes is what your seeing on your altimeter too. If it differs, they may have you as a pilot turn off the altitude encoding on your transponder so they don't reference it while providing you radar services. www.law.cornell.edu/cfr/text/14/91.217 www.law.cornell.edu/cfr/text/14/91.215

I was thinking the same... I would have been covering all the faulty stuff up. Not sure what instruments are on board, but if available I would have used the GPS... it can give a good altitude reading and ground speed reading good enough when nothing else is available. The captain seemed to sort of panicked. I've had some heart thumping moments at various times. Key is to always stay calm. Just look out the windows... can't see much, stay with in the lights you can see, or have the controllers direct you to places you can get a visual reference. Panicking only makes things worse. Use the freak out feelings for acting with a sense of urgency... but don't lose your mind. Of course with GPS and some other training today makes me a real arrogant saying that. But sometimes the truth is rather arrogant. Panicking never helped anyone. So you have to take a deep breath... force yourself to smile and even laugh at the predicament... and even fool yourself into thinking no matter the problem, you'll figure it out. Either way, you're going to live through it... or die... okay... let's see what nonsense we got ourselves into... and start going through the troubleshooting steps.... with another pilot aboard this means listening to them... the captain seemed out of ideas. The copilot seemed to be full of ideas, and he was in fact correct each time. Sucks they all died. Makes me sick to my stomach.

A minor correction is that it wasn’t pitot tuber gets taped, it was the static ports got taped.

Controllers verify altitude on their scopes because it's coming from the transponder on the airplane.

Controllers should have advised this to the pilots. I can give you what we're seeing on our scopes, but this same information is coming from your aircraft that is having altimeter problems... so it is likely faulty information. You need visual references, let us direct you to the coast line where you should see lights to provide you with something to reference your altitude with. To continue to state altitude information on the scope is sort of odd. Altitude verification is a common step on initial contact with a radar services controller. Perhaps they had radar, but they weren't really a radar servicing controller so they didn't know? As a pilot, things can become very stressful. That's why training is essential and watching these videos is very helpful. Hope this helps to prevent from ever being that "that guy".

From what I know about this accident it was not a pitot tube that remained covered with tape (the tubes are covered with special hoods) but a pitostatic port. These ports are found a bit towards the underside of the plain not on the sides. They are flat and more difficult to spot in low light, even more if it was covered with tape also covered in paint. Very hard to see. The pitostatic port helps in determining the altitude. This is why this plane had such problems with its altimeters and all the related problems and completely illogical alarms. Half of the plain (the captains) was seen as on the ground and half flying. The onboard computers were completely confused. What amazies me the most is that the aviation industry still hadn't found a technical solution that would allow pilots to check the functioning of these essential sensors before flight and that would clearly signal that they do not work anymore during flight. It should be essential. Also it is amazing that airplanes still do not have other redundancy systems for measuring the altitude and their speed in case these sensors do not function anymore. I mean...a simple vertical laser would allow pilots to check the altitude and speed relatively to the ground in this kind of situations. 🤔

I answered this on another comments so I'll just copy and paste it here: Yes, I've heard this many times and I'll attempt to explain as concisely as I can If this exact situation had occurred in Houston or JFK, then yes, turning back would be smart as the areas are flat, well lit, and no sizable terrain. However, Lima has steeply climbing unlit mountains very close to the airport that turning around is far more dangerous than going out into the ocean and troubleshooting there. You wouldn't even be able to use the city lights for reference. To showcase this, if you would indulge me, I would like you to place your hands flat underneath your nose, parallel to the ground like a giant mustache. Tilt your head up some 10-15° and answer honestly: Can you see anything below you? I should also add, the pilots don't know what's wrong. Loss of control was a very real possibility needlessly risking the lives of Lima below

@@RacinZilla003 I also try to constantly answer the same comment about the visual return. This is unfortunately the third "producer" of this accident with the same visual flaw. My standard reply goes something like this...This presentation is severely misleading in the visual aspect. Seen here this aircraft takes off as if in a scenic sightseeing tour of Lima for 3 whole minutes at reduced power where the whole city and coastline are neatly shown (probably for some extra "likes" for fine graphics). Remember it is overcast skies from 900 feet (270m) this night with 6 kilometers visibility. This B757 is going to Santiago which is a 3 hour flight carrying 60 passengers. This aircraft can carry 180 with a range of 8 hours so the load is very light and the B757 is well known for it performance, so given a conservative initial climb of 4000 feet / minute this aircraft would be in the clouds already 15 seconds after takeoff. Even if the crew wanted to level off at 900 feet this would have to be initiated early so as not to overshoot. Say 500 feet, so it would have to be initiated 8 seconds after takeoff. There is no way anyone could identify and react to a problem like this without prior knowledge and training. Once in the clouds a visual return is not possible before trouble shooting and finding the root cause. In the accident report the tower controller reported seeing the aircraft entering the clouds before reaching the departure end on the runway .There was also no mention in the accident report regarding the crews choice to continue over the ocean vs a visual return. (There is high terrain already 10 miles east of the airport - foothills of the Andes)

[@RacinZilla003]

@@mortenguld3076 Wow, I wasn't aware of the meteorological conditions of the accident. Thanks Edit: Sorry, minor correction. The foothills of the andes are much closer, less than 4 NM to the east of the centre of the runway

I don't think it matters, Lima is a very foggy and cloudy city, even on land i don't think they could have seen the lights on the ground

[@mckungsmakong]

Thanks!

[@whaateverrify]

Excellent video once again! I imagine all the faulty warnings contributing to a very stressfull environment, I dont blame the pilot for being too confused to reject the FO's suggestions. Also is it not possible to see any stars in the night sky?

[@ByzantineDarkwraith]

are you actually suggesting that they keep track of their altitude by keeping track of how far away the stars are, or? (and also they always had a radar altimeter available to give them an altitude reading... that's what the ground-proximity warning system/"too low, terrain" alarm works off of)

[@whaateverrify]

@@ByzantineDarkwraith not actual position obviously, but flight direction

[@lordmarcusrax]

22:08 Pilot: "We are impacting water!" Lima: "Go up if the indicator indicates pull up." Yeah, no shit.

[@ApexWalrus]

What I'm learning is there are never enough Pitot tubes on an aircraft

[@sulimanb1833]

Doesn’t matter how many there are. Even if one is obstructed it will lead to confusion for the flight computer.

[@Admiral_Jezza]

@@sulimanb1833 But you'd think the flight computer would be able to detect if its blocked and then just ignore information from it as the info would be wrong.

[@aidancoutts2341]

Static port* pitots are just airspeed

[@louigee1450]

Great video. Love the length format

[@change_your_oil_regularly4287]

With this incident I've always thought things may have turned out differently if the FO were the captain. He seemed to realise just how desperate their situation was long before the captain did.

[@Elon-db6ds]

An incredibly tragic and totally avoidable disaster. Very sad!

[@EdmundKempersDartboard]

Appreciate the CVR warning. Anyone hesitant to watch because of that you will hear the pilots in obvious distress, but it is not nearly as bad as some of the stuff available on planecrashinfo.

[@MechaNick767]

It saddens me that you don’t differentiate between the Pitot tubes and the static ports. The Static ports were the ones that were covered with tape and not the pitot tubes. Covered pitot tubes would not give you a wrong altitude instrument reading on a 757, only speed readings on the speed dial/tape. (Like what the Birgenair had) The static ports however are connected to both height and speed reading through the Air Data Computer (ADC).
