I used to fly with the same aircraft and captain for almost two years. There was a protection system that gear must be down and air/ground sensor must send the signal from the shock absorber to the solenoid to let the throttles go to ground idle. After a similar accident happened before this crash, Fokker maintenance company(Stork) published a non mandatory service bulletin about the air/ground switch box to be modified. That service bulletin became mandatory after Kish air crash. Infact a few days before, on approach to DXB the left propeller went to ground mode but luckily as soon as the crew executed go around and retracted the gear, propeller went to flt pitch range again. Unfortunately the incident wasn't reported properly by that crew because they didn't know what really happened. A few days later, the crew of 7170 were not that lucky and never tried to retract the landing gear. It was impossible to intentionally put the throttles in ground range because of that solenoid lock. I believe it was not pilot action and at least one engine went to ground pitch mode (uncommanded). Obviously the solenoid lock wasn't engaged (which should be) and there was uncommanded transition of at least one propeller (left) to ground mode. Why the service bulletin wasn't mandatory and after the second crash it became mandatory? Obviously there was a flaw in the protection system.

This thought occurred to me as well. Sometimes an innocuous thing can trigger an anxiety attack. The more pressure there is the worse the anxiety, and the worse the anxiety the harder it is to pull yourself out. The only thing that works for some is to pause and separate from the situation for a few moments. In a fast-developing situation there’s no time to pause. Sometimes it happens so suddenly that I can’t even articulate the problem, which causes confusion amongst others around me. I’m not saying that this is what happened to the FO, but if it were, it could have happened dozens of times in his career, but at times when he could mentally pause and recover without anyone knowing that it ever happened. From watching this and similar channels I’ve learned that the cockpit culture isn’t as conducive to showing any apparent weaknesses as other industries.

It’s miracle how 3 people even survived that crash.

I mean... the original ACI / Mayday show was a completely different genre of content. I wouldn't call the non-mini version unprofessional, just over-dramatized. They were editing to meet network time constraints and ad breaks, and they had to build pathos to capture the attention of a very broad audience. Their newer episodes are shaped by the same constraints. MACI wants to be concise and informative, so they only manage suspense enough to entertain; but they don't focusing over-much on drama, because they're looking to capture an audience that's already sufficiently fascinated with aviation incidents to stick around. Plus, KZread tends to very short videos with much looser length constraints. Both productions made valid choices, based on their respective distribution mediums and intended audiences. The rest is just the preference of the viewers. I know I, for one, wouldn't care nearly as much about MACI-style videos if I'd never sat down in front of my TV as a kid, absolutely enthralled with ACI, even though I prefer the more concise, informative style now.

Totally agree sir! But then, TV series on disaster subjects are all about holding back The Moment, maximising number and duration of hypotheses before the reveal. They try to keep the viewer captivated, including right through the multiple ad breaks too, a hard enough task in my case! They always repeat the last 20 seconds of the pre-ad-break moment on re-start afterward, as if the average numpty viewer will have forgotten what was going on. It's almost a way of reducing our attention span to seconds, as if we might need reminding about half a dozen important points frequently, because everything is being dumbed down, bit by bit. Regarding incidents like the one above, perhaps this should be an alarm call to aircraft manufacturers, airlines, and pilots alike to allow pilots to do more flying assuming PLENTY of genuine experience, and not to hand over too many of a plane's controls to digital technology. I realise I have steered away from the video here, more like getting into another pet hate of mine - that modern airline pilots barely fly anymore, the 'plane does it all bar a disaster.

I love how you always show the plane landing, makes me think of an alternate universe where everyone made it home

I think this is a classic case of a captain who had to take over from an aproach which was not properly set up by the first officer. The captain was taken a bit by surprise of the reaction of the plane when he took over and did not immediately recognise the mistake. By the time he had to rectify the mistake the engines took too long to respond to corrective action. Since the approuch was so easy and routine, the pilots could've been too relaxed and not fully aware of the imminent danger. A case of temporary mental incapacitation could also have played a role. The captain put both engines to full power. This could've cause the left engine to pool up into full power but in reverse pitch momentarily , which was disasterous for the speed and low altitude they were at. A similar accident occurred in Scotland while the pilots were landing in dense fog with a similar type aircraft which overturned the plane on touch down when one engine went into reverse just before landing.

Kindly refer to my comment regarding this accident.

I know why the co-pilot didn't feel comfortable. Here is what I saw happen once: I was a teen, my dad was a flight engineer on the 747 flying for Iran Air. We were flying back from a vacation to Tehran from London and my dad was in the cockpit and got me in there for the landing. On final approach the captain gave the landing to the co-pilot, maybe 5 min before landing. I distinctly remember that the flaps didn't extend so my dad initiated the alternate flap extension. All was good and the plane was stable and needed to make a left hand turn towards Mehrabad airport. The co-pilot made a 45 degree turn and the pilot took back control of the plane. The co-pilot couldn't even turn the damn plane. Many co-pilotsin Iran are young guys with connections with religious leaders and get placed in these positions as a favor. This was 30 years ago, but I remember it distinctly.

Yep, my first theory. An experienced FO afraid of landing in perfect conditions? WTF? It’s not like “my breakfast burrito was bad” or “I have severe vertigo” … If the FO was *not* the person that the credentials belonged to but someone with limited experience, and the captain knew (or suspected) that, what better place to get the fake FO to learn flying a bit - in perfect conditions? The captain seems to have coached him … Given that corruption is not unheard of anywhere, it certainly is possible that the paperwork was not quite correct about experience and/or person. That would explain a lot of things - but it certainly is not the only possible explanation.

On the planes that are RATED FOR reverse thrust in the air (a handful of military jets, some tailjets, and a few turboprops with a lot of wing area outside the disturbance cone of the engines) the most common usage case is making steep approaches to short runways, using it to bleed off speed while approaching above the glideslope, basically speedbrakes but stronger. Moving the propeller angle control into the ground range, but not into full reverse, is a common enough (but obviously unauthorized) trick on the turboprops with manual overrides to salvage a too hot/too high approach, allowing the propellers to be basically flat to the wind and engine braking to slow down without going into full reverse, however ground control range definitely is dangerous cause it's too easy to push past 0 degree pitch and into reverse pitch. So, if I had to hazard a guess, someone was trying to salvage the approach and bumped the pitch lever a little bit too far, spoiled the air over one wing and couldn't push it into positive thrust fast enough to recover.

I feel the first officer should have rejected control quickly if for whatever reason he felt uneasy about it. When I have given any of my peers "control" of a procedure and they rejected it, I never argued about it but waited a good period of time before touching on the subject. I waited patiently untill they were confident to try the experience. This had paid off many times resulting in good engineers rather than "aint-gineers".

The narration and facts are just out of this world this channel is sure worth every bit of it's onion

One possibility is that FO could have been returning to the cockpit after an extended time off. That could explain why a pilot with a good amount of flight hours and hours on-type might have been excessively nervous or felt a lack of proficiency. There have been incidents where very senior training captains made baffling mistakes because they were spending so much time in the simulator and in ground school training other pilots that they rarely flew on the line anymore. Currency is just as important as experience.

Maybe the FO was feeling sick? Maybe he had some sort of memory loss or cognitive difficulties? Hell, maybe he had something stuck in his eye and was embarrassed to say it was a problem to a superior?

For years I was the dispatcher for Security & Safety and emergency maintenance at a large Chicagoland hospital. I assigned tasks to a crew of 7-16. My crew was free at any time to ask me to delegate others for any call they didn't feel up to taking. I never asked for a reason or an excuse nor did our other members. We deliberately fostered that mindset because many of our calls required appropriate response from people who had their head in the game. It only happened rarely, but we had the smoothest running, most effective and cohesive shift. I would often be told after the fact what the deal was but most times it was a transitory situation. For ongoing difgiculties I could cater the calls in the future. For example, I had two officers who couldn't deal with morgue calls, and one engineer who had had a rancorous breakup with a floor staff member. In any case we were able to handle our situations effective, safely, and professionally. Everyone was happy and problems were easily avoided because of the work environment we had fostered.

The irainian final report mentions 3 resons: 1. Captains insist on fo flying the plane impaired the crm and ignoring cockpit protocols. 2. Applying incorrect method for reducing speed.... 3.

correct. The reverse pitch angle of the blades is so that the aircraft can slow down on landing and taxi. There is a mechanical stop on the power levers that prevents reverse pitch. The pilot must physically override the stop by pulling up on the power levers and moving them into reverse or ground fine range.

If that's the case, why would it be possible to put the plane into ground control range at all whilst still in flight? As I understand it, on jet planes there are multiple checks to ensure that the plane has actually landed before the engines can be put into reverse thrust - why would it not be the same in the case of this turboprop? Is there actually some crazy scenario where you do need to put the props into ground control range while still flying? If not, this seems like a major error on the part of the manufacturer.

I remember hearing the phrase: "an accident looking for a place to happen." Thinking it applies here

A crash similar to this would be the Mohawk Airlines flight that crashed into the house in Albany New York in 1972. It was a Fairchild Hiller FH 227 very similar to the Fokker 50. They too had a problem with the propeller pitch on the number one engine or the left side engine. They couldn't get it to transition from Cruise pitch to flight fine pitch to set up for landing and their preoccupation with trying to shut that engine down and feather it, as it would not feather, allowed them to get too low and too slow and before they realized it, adding full power to the operating engine was insufficient to bring them out of an inevitable meeting with terrain and the aircraft ended up crashing into a house lifting the house up and the house falling back on top of the airplane but there was no post crash fire..

The house?

Theory : the captain thought it a good idea to activate reverse thruster to reduce air speed without informing co pilot, who panicked and tried to intervene at the point where 1 engine was in negative pitch and the other was responding to the go around. Asymmetric thrust with little altitude to manoeuvre. Note the simulation might have been too vertical for 3 souls to survive. IMO

No, reduce thrust and regain profile yes, then hand it back and coach if required. This has the hallmarks of a technical issue.

Was just reading the Yeti Air crash initial accident report and it's figured that the co-pilot feathered the props thus losing air speed. They figured she meant to extend the flaps. Not exactly the same, but similar.

I believe it was determined that the check pilot who was monitoring her flight performance just prior to her anticipated promotion was the one who moved the wrong lever when she requested additional flaps down. What a tragedy.

As a result of watching this channel, I want my eulogy to begin: _"This..._ is the story of a pathetic old man."

The possibility that this was an intentional sabotage by the FO is troubling. The unlikeliness of the FO trying to take his own life and sabotaging the plane as he was handing over to the captain seems surpassed by the unlikeliness of any other option. The lack of confidence could easily be read as an unwillingness to be pilot flying during the crash, as well as nervousness about what he may have known was about to happen, or even a planned way to distract the captain. This is completely speculative, of course 😂

It is unprofessional to hand over the controls to the other pilot on final approach. Unless the pilot flying experiences a problem, like incapacitation. The approach is briefed before the airplane starts to descend, and from then on, there should be no doubt about who is flying the airplane. Secondly, when the first officer objected, the captian should have continued to fly the aircraft himself. So sad, so sad.

Weight on wheel switch must be in series to this ground control switch so until both main landing gears hits ground and weight on wheels cross certain limits this reversed pitch will not activate...

Great video.

While the state of mind of the FO would be interesting to examine, I'm more curious as to why, being close to landing, the Pilot just didn't look at the situation and go around? I get Turboprops are slower, great weather, etc., however, it seems to me that this is just a classic situation to go around and do it right.

It's sad and scary that one person's incompetence and/or lack of confidence can kill so many people.

This week I was being trained (poorly) by a Treasurer in a new job. Even though I had understood the task, I told her I couldn't close the shift too fast, since it was my first time. She arrogantly insisted I did it, an argument ensued, resulting in me passing her the task midway and storming out. I believe that a Captain, unless incapacitated, should always take over when the FO clearly can't do it, not force a bad situation into something worse. RIP all victims.

Thank you for all the great Videos! After watching your channel I will NEVER fly again, no way!

I really like these story-like narration. With your soothing voice, maybe you should publish an audio book of some sort. It's likely that it'll sell well.

To say that I wanted to scream for my life when I saw the plane dive towards the ground is quite an understatement

I have 3,000 hours in the F-27. This Fokker F-50 is a variant with system and engine differences. Note that the Dart engines and the Rowty-Rotol propellers on the F-27 have a spring colette at the 16 degree (or 20 degree) angle (depending on the engine/propellor installed. If these locks fail to engage due to unwanted oil pressure retracting the Flight Fine Pitch Locks (FFPL) then there is a hydraulic system that uses the feathering pump to provide oil pressure to maintain a proper angle of 14 degrees or more. All of these are to prevent “disking” or flat pitch (measure at .7 the radius of the propellor blade). At cruise, there was also a Cruise Pitch Lock (CPL) that restricted the propellers to 28 degrees or greater. These were to negate an asymmetry of one prop should it go to a low pitch stetting in high cruise while the other did not, which would cause sever asymmetrical thrust and torque. On the ground, below 60 knots, a power lever could be moved to allow the blades to go to zero pitch. This was an electrical circuit and there was a second one via the gust lock, which also gave the signal remove the FFPLs and to cancel the auto-coarsening, Hence, the blades went to flat pitch and the drag slowed the plane (no reverse of the blades was available other than the blade beyond .7 radius was slightly or marginally negative. Some operators of Pratt and Whitney PT-6s, have used reverse in flight to slow down in flight. This is a capability of this engine/prop combination on some aircraft, although forbidden by procedure. Could it be that this was a contributing factor here? I doubt it based on the previous commentator who is more familiar with the F-50 engine/prop systems. If the prop slipped into zero pitch, the results would be exactly what was demonstrated by this aircraft. This scenario is exactly why the F-27 with RR Dart engines had two ways to prevent zero pitch in flight.

The logic on "ground based" systems, whether they be ground spoilers, thrust reverse , sometimes even beta range on turboprops have an input from a weight on wheels signal. When that, "if" that signal is not present, the protections can, in some cases be lost. Other inputs can but do not necessarily radar altitude and configuration depending on the aircraft type. I have had a weight on wheels sensor go strange on me, which only limited the lift spoiler deployment after landing, but curiously, it reset again before takeoff. We checked the protections before departure for the rejected takeoff case, but on every landing, one spoiler set would not deploy, and this was traced to a weight on wheels signal. Although the specifics in your video are rather sparse, a follow up on the tech log history for this airframe would be illuminating.

You do great work. Can you do one on Mohawk 405?

Last time I was this early, we were still boarding!

I have actually increased it tbh. That’s weird

C-130 is a military aircraft so presumably the first officer had been in the military. For this reason, I wonder whether he was having one of the random panic attacks that happen sometimes with PTSD. I know it's happened to me driving before and I had to pull over and let someone else drive, not because I'm a bad driver or an inexperienced driver, but because the nature of the intense panic I was feeling made it unsafe for me to drive at that time. It happens and it's a good reason not to ask our young people to go to war unless there is absolutely no other choice. We have enough potential sources of PTSD in normal life that we don't need to add the additional risk of sending people to war.

Nah we do not want that. Using video cameras in the cockpit would only add to the likelihood of misinterpretation. Beyond worries that what cameras record might be misinterpreted or misused, pilots say the very presence of a video recording system could be detrimental to pilot performance and decision-making.

Thank-you!

reminds me a little bit of the loss a FOKKER from LUXAIR just before landing on Luxembourg airfield some 20 years ago

Installing a safety warning device related to the thrust reverse deploying was had been required by the manufacture that Kishair had not done...

This crash must have been particularly horrific for the passengers.

Your voice is so relaxing

"It's a cultural or professional issue." Well, that's nice and specific and clears thing up 🙄

Slight issue in the title as it says 46 people died, but once again another excellent video

How very strange. The only explanation I can think of, unlikely as it sounds, is that perhaps the F/O was an imposter who had taken the place of the real F/O. For example the real F/O had wanted to miss work that day and had sent his brother to take his place, who had enough informal flying experience to bluff his way into the cockpit and complete checklists etc., but was completely unqualified. The captain either did not know the real F/O well enough to spot the difference, or was complicit in the deceit and had decided to give the unqualified pilot an ad-hoc flying lesson (but without saying anything incriminating in the cockpit, knowing that the CVR would record it). In either case it would not then be implausible to believe that this was never discovered, with the wrong person being declared deceased and the real F/O and his family never revealing the truth (perhaps carrying on life under the imposter's name, or perhaps just moving away and carrying on under his own name - after all if banks etc. are not explicitly told that a customer is dead, they would not freeze the account, and things such as driving licences and passports are not cancelled automatically when a death certificate is issued AFAIK). There was the guy in the film, "Catch me if you can," who bluffed his way into the cockpit by pretending to be flight crew (but in that case as a "dead head" rather than actually flying the aircraft), but I have no idea how well the film matches the real events. And the Russian captain who allowed his children into the cockpit and gave them an ad-hoc flying lesson which ended up crashing the aircraft.

I have 11,600 hours flying the F27 Fokker Friendship over 17 years (That is not An F50's engines). I did a lot of training work & some Checking on the F27 & we were very aware of Ground Fine Pitch being able to be selected in the air by pulling the throttles back over the spring loaded stops ( The props are actually zero thrust except near the engine intakes). On the panel near the Captains side is a switch called (Auto Corsening) & if you switch that quickly it will pull both props out of Ground Fine & would have got them out of the problem.

Fascinating x

It would be awesome if you could add some cockpit recordings.

The second officer's reluctance to suddenly and unexpectedly be tasked to fly the approach is not surprising; such arrangements should be discussed and agreed before departure.

Something similar happened at Cork Airport (Republic of Ireland) 10th Feb 2011, where one of the propellers went into reverse thrust at treetop height, inverting the aircraft, causing it to crash.

That's very strange, a bad design for sure. How can it go in Ground control mode when it is still flying in air? Ground control mode should be enabled only after wheels start rotating on ground. Such a small mistake and so many lives are gone in fraction of second.

This is chillingly similar to what happened to the Yeti Air flight. Something that should be unthinkable in an aviation setting actually takes place.

The pilots do not sound perfectly "Sober" esp the 1st officer. Maybe they had some Quat or hash ? Or maybe just No. 1 ? Why would an experienced pilot on a perfect day get nervous. So nervous that on surrendering control he messed up the throttles trying to put them "back" to where he thought the captain wanted them. If he was in awe of the captain he would not have lost face be admitting his fear. The report mentions "cultural" issues. This is very odd. The 1st officer seems to be really incapacitated. The Capt seems to be aware of this. He is kind and unsurprised by his co pilot being wobbly. Why ? if he knew No.1 was in a funk why give him the landing ? Beats me what went on that day.

For a span of about five years, I had ocular migraines--maybe three times a year. Confirmed and diagnosed by the chairman of ophthalmology department at a university medical center and a neurologist. Symptoms always occurred at my office, at a time when I had been focusing on my computer screen for hours. Several times they occurred when leaving the office for the day, but still inside the building. Sudden onset of sparkling colors in my peripheral vision, but then moving toward the center of focus until I had just a peep-hole of clear vision. I would immediately find a seat, close my eyes, and start some deep, slow breathing. Lasted about 7 minutes. Was like when you were a child, looking through a kaleidoscope. Was always worried about onset while driving at rush hour. Been ten years since the last one (Being retired, I don't spend so much time staring, straining, and forcing my eyes to focus on the monitor. ) Easy to understand an experienced pilot who has these episodes, but who does not want to reveal them for fear of losing his job, license and certification. Scary stuff, indeed.

I'm not sure what it was (since I never went to a doctor) but when I was a fulltime student and working fulltime and having marital problems, so I was BEYOND overstressed, I started having migraine attacks where my head would feel like it was popping or exploding, followed by 20 minutes of agonizing pain where I could only lie flat on my back, eyes closed and could not really speak. The first time it happened ever, It took me at least 5 minutes to tell my wife what was going on. If I was responsible for landing a plane, it might be so confusing the first time it happened that I might think "I must land the plane" and not communicate properly that I was having a medical condition and just kill everyone, I can totally see a migraine at the very wrong moment killing someone.
