What STOPPED this Airplane from flying? | Air Crash Investigation

Imagine if it was a first time pilot performing the take off. They wouldn't have known until it was too late!

[@prant8998]

THAT, was a tough decision. He knew, there was going to be a some damage and he was not going to be able to taxi back, at the very least. But, question, what would have happened if he didn’t abort? Probably a catastrophic accident. The three second plus delay in actual rotate told him something was amiss. How about, some kind of catch cables at the end of the runway to grab the landing gears like they used to have on aircraft carriers? The extra speed, put the window of, go or abort, at an almost inhuman decision point. Either way, there was going to be an accident. I guess with the extra take off speed the plane should have responded quickly. What happened to the plane???

[@marcohueber5130]

@@prant8998 I don't think catch cables will be useful for this type of super heavy airplanes. Airplanes that can take off or land on an aircraft carrier are all small and light, not massive behemots like those. I believe if catch cables were used, the extreme stress they would have to withstand would easily cause them to snap and maybe whip the airplane with incredible force, or destroy the landing gear and cause the airplane to hit the ground from the nose or wings. And remember that during take offs the airplane has lots, lots of fuel, you really don't want to cause situations where there are higher chances for something to go wrong and ignite it. All in all, I believe catch cables are too dangerous to be used on big modern aircrafts.

[@davidlarocque1291]

I flew MD-83s as a captain for TWA. I never had an aborted take-off, but I had an aborted departure. I am a former naval aviator and I had extensive experience in various models of the DC-9 and MD-80. Our version of the MD-83 had a dual laser gyro system which provided gyro inputs to the captain and first officer artificial horizon instruments. I was departing PHX on a very hot day with a full load of passengers and fuel for a long flight to JFK airport in New York. This meant an unusually high Vr speed. At rotation a very loud noise on the fuselage below the cockpit accompanied by a severe jolt to the airframe told me that one or both of our nose wheel tires had failed. I quickly realized that both artificial horizons had also failed, which disabled the autopilot. Fortunately the weather was clear VFR, but a return to PHX was necessary and we were well above max landing weight for the airplane. We circled for several hours at a nearby location while we attempted to restore gyro operation and prepared the cabin for a likely emergency landing. Direct contact with company engineering support did not help, so we elected to land overweight after burning off a substantial amount of fuel, and made a low pass by the tower for them to get a look at the condition of our nose gear. We were told that it appeared that both nose tires were "shredded". We called for emergency equipment to be standing by for the possibility of a nose gear collapse and a runway excursion. We made a soft touchdown and once the nose gear made contact with the runway the nose attitude and roll-out seemed normal. We stopped on the runway for a nose gear inspection by the crash crew. They plugged in and told us that only one nose tire was damaged. So we were able to taxi into the gate, get both nose tires replaced, complete an overweight landing inspection, clear the dent in the lower fuselage from the tire tread impact for flight, and get the laser gyros reset. It turned out that the laser gyro system had an automatic shut-down feature based on a 6g sensor that nobody knew about (not resettable in flight), and which apparently tripped with the impact of the nose tire tread on the fuselage. Our flight to JFK was normal, but we sure needed the flight instruments for the weather in New York.

Or the infamous stabilizer trim which was central in the Alaska accident. Or how the 2 control columns are connected and can be split if one column is jammed. It is a really fascinating design.

[@bob2161]

@@adb012years ago when I learned of some of these things about the DC-9 and descendants, I was amazed that such a Rube Goldberg design worked as well as it did, with any kind of reliability. The thing that struck me most was that the pilot had no direct control over what I had always considered to be most important. I was not aware that the control columns could be separated. That's a rather unusual feature. I can't help but wonder if that feature was ever employed during an actual emergency.

[@adb012]

@@bob2161 ... Most planes (at least the ones that are not FBW) have control columns that can be separated so in case one gets jammed you still have at least 1 control column and one side of the elevator. I don't know if this feature was ever used in a DC9 but it certainly was used in other types, and successfully so, saving everybody on board of an almost certain death. And I don't consider this to be a Rube Goldberg design (i.e. a complicated way of doing a simple thing). Compare with a hydraulic system where you have engine-driven pumps, electric back ups, reservoirs, hydraulic lines, valves, pressure-transfer units, etc... I see it as a very effective way to move a large control surface with little force using a low-tech solution. By the way, the ailerons are also like that. One day, before I knew how this worked, I had a nice scare taking off in a MD-80 and seeing how we were accelerating with the aileron fully deflected. I didn't know that the position of the wheel didn't directly command the position of the ailerons (just their control tabs) and that very soon the aerodynamic forces would center the ailerons, as they ended up doing.

[@cr10001]

@@adb012 That mention of the hydraulic boost is interesting - I was going to query the use of servo tabs on a T-tail. Bearing in mind the accident to the prototype BAC 1-11 that got into a stable super-stall and they couldn't get out of it (so BAC changed the design to fully powered controls). But I guess the hydraulic boost looks after that.

[@NicolaW72]

@@Dmoneyaka Indeed. It would have become a major crash with probably more than hundred casualities.

[@adb012]

Well, not trying to be the negative guy here, but... - SOP says that have to reject the take off after V1 if the plane is unable or unsafe to fly. - If they insisted with continuing the take-off and managed to rotate and get off the ground, they would have probably been ok to keep the plane flying. It takes more nose-up elevator to rotate than to keep it flying (that's why you can see that the pilots move the yoke forward after they rotated to the initial climb attitude, if not they would continue pitching up). Now, if they insisted continuing the take-off and they were unable to lift off, it would have been a disaster. I suspect that they would have lifted off igf they had pulled back harder, but I don't know for sure. I am even more confident that they could have done it adding more nose-up trim, but we cannot count or even expect that the pilots would have done that.

[@thetowndrunk988]

@@adb012 It definitely, without question, would have never taken off with one elevator stuck in the full down position, and the reason experience is key here, is because a lesser experienced pilot wouldn’t have considered it SOP to reject the take off that late.

Two neat follow-ups to this story (and I apologize if the second one was already mentioned in the comments) : 1) The captain, Mark Radloff, was my school bus driver back in the early ‘90’s. Just a few weeks ago, I stumbled across some old letters. When I was a young avgeek (age 9 or so) I remember asking the bus driver if I could be his pen pal because he told us kids that he was working his way through flight school. He obliged and, after quitting his job as a bus driver, wrote to me. First, he apologized that he had to quit his bus driving job. He explained that he was so busy with his other job-a flight instructor at the Waukesha airport in Wisconsin, USA-and that he had just been hired on as a first officer at Mesaba Airlines, a regional company associated with Northwest Airlines. I didn’t keep in touch much more beyond that, but when I found those letters the other day I decided to do the adult thing and Google search him. At a quick first glance, I saw his name associated with the words “air incident” and feared the worst. But I read on and found that he had been the captain of this flight! He was 54 at the time, which means he was probably only in his early 20’s when I met him. Clearly he was dedicated and passionate about aviation, already being a flight instructor and becoming a first officer that soon. I will keep his letters forever. You were the coolest school bus driver and became a hero… AND made your way into a Mentour Pilot video! Way to go, Captain Radloff! 2) The Michigan Wolverines went on to win the Big 10 Championship that year.

Watching this channel, and others, made it so much more interesting to watch. They did a low fly by so the ground crew could see what was wrong (something with the front tire). They circled for a while to burn fuel I assume. Then, when landing they came in real slow and then kept the front tire up as long as possible. Once the front touched nothing crazy happened and they slowly came to a stop at the end of the runway. All of us watching were super excited and happy for the pilot to execute a great landing in an emergency situation.

What’s not good to see is this is an obvious huge design flaw that everyone is glossing over as if it’s no big deal. It’s entirely possible to design mechanical linkages that cannot jamb as happened here. If someone told you you couldn’t drive your car if it was parked outside in a storm because the steering might fail until the dealer inspected it would you consider that okay? That’s basically this situation. Instead of fixing the incredibly poor engineering by McDonald Douglas Boeing just issued an advisory that even experienced pilots were apparently unaware of or didn’t think was applicable. You shouldn’t have to computer model wind speeds on the ground to know if an aircraft is safe to fly. Why do pilots put up with this crap and things like the even more poorly designed MCAS system on the Max even after the first Max crashed?

Phenomenal reactions by the pilots. It's always great to hear about an experienced pilot's instinct that something isn't right, and not trying to be a 'hero' by taking off anyway. My initial reaction to what happened being due to a known fault (even though the wind conditions were different from those warned about) is to place all the blame on Boeing/MD for not having corrected the fault on each plane after the first time the defect was discovered. These bulletins _might_ be sufficient warnings *if* every active plane of that class is in the process of being fixed - I get that smaller companies can't afford to keep their planes on the ground for extended periods - but to just issue the bulletin and do nothing is criminal IMHO.

[@scottkirby5016]

well how long has this type of plane been flying? Since the 80's at least. How many have been lost or had something like this happen? It seems to have been a very unusual occurrence. The problem seems to have been well managed for 40 years from the initial..."park this way" and "after high winds have engineer check this". Finding out how often jams were detected by said engineers would be interesting.

@@scottkirby5016 It's stunning to me that a control tab or elevator can be forced into a locked position. On top of that that there is no indication of when it is in this locked position.

[@scottkirby5016]

@@brianwest2775 honestly I don't think it would have mattered. If the Md-80 had a problem it was with those surfaces that did have sensors. Northwest 255 in 1987 and Spainair 5022 in 2008 both crashed due a lack of both the flight-crew setting the flaps + slats for takeoff and the alarm to tell them this failing. And while we think of such sensors as cheap, easy, and reliable today they certainly were not in the era this plane was designed (launched in 84 for this model and no major generational updates I saw). For comparison when such tech become normal in the 737 etc?

Sir: (Mentour Pilot). I’ve been enjoying your videos a relatively long time with great satisfaction…. I must say two things where you far excel everyone else…. First: There’s a decent degree of balance between reports of “all on board have survived” AND some damage with why and what we’ve learned .. and obviously some where “no one survives”. That’s SOO much better than a steady diet of utter catastrophe !! And second: you never are “unnecessarily critical” of any pilot - airline - or even maintenance/ground crew! You accept ALL as fellow human beings with various levels of dignity…. Kudos !!

When I saw the positions of the elevator, my heart dropped. Trying to take off with that could only end in disaster. Even if that plane became airborne through some miracle, it would've been likely uncontrollable. I'm so glad the pilot made the right decision. Aborting above V1 takes a lot of courage, and luckily that captain had it.

[@aldenunion]

I think of the Alaskan air flight turning inverted when bolts fell out of Elevator controls.

[@rainscratch]

Another example of really shoddy Douglas engineering design.

[@recoilrob324]

@@aldenunion Actually it was the jack screw nut that failed. Both screw and nut control the elevator trim and the worn nut had been rejected in an earlier inspection by an A&P but he was over-ruled by his supervisor who told him 'we'll fix it next time'. But 'next time' was a couple years away and they didn't make it that far. Just imagine trying to fly when your elevator is jumping from way up to way down erratically because the worn screw and nut can't hold the forces anymore. Things like this do go on in the airlines at times which is distressing....some will put the need to get the plane back into the air over any possible safety problem. Was anyone at Alaskan held responsible for this? From Wikipedia (and this jives with my memory) In 1998, an Alaska Airlines mechanic named John Liotine, who worked in the Alaska Airlines maintenance center in Oakland, California, told the FAA that supervisors were approving records of maintenance that they were not allowed to approve or that indicated work had been completed when, in fact, it had not. Liotine began working with federal investigators by secretly audio recording his supervisors. On December 22, 1998, federal authorities raided an Alaska Airlines property and seized maintenance records. In August 1999, Alaska Airlines put Liotine on paid leave,[25] and in 2000, Liotine filed a libel suit against the airline. The crash of AS261 became a part of the federal investigation against Alaska Airlines, because, in 1997, Liotine had recommended that the jackscrew and gimbal nut of the accident aircraft be replaced, but had been overruled by another supervisor.[26] In December 2001, federal prosecutors stated that they were not going to file criminal charges against Alaska Airlines. Around that time, Alaska Airlines agreed to settle the libel suit by paying about $500,000; as part of the settlement, Liotine resigned.[25] What to take from this? The FAA is NOT a 'watchdog'....more like the cop that outlines the body on the ground with chalk then tries to figure out who killed the guy. Yes they'll make recommendations after an accident, but if you try to prevent something bad from happening....and this has happened at least once that I'm positive of....they won't lift a finger. Look at the Value Jet crash in Florida where oxygen generators were improperly safed and shipped. The FAA had been notified at least a couple times by one of the mechanics who was worried about this....and what they were doing was flagrant disregard for many rules...but the FAA didn't respond and wouldn't even go to bat for the guy once Value Jet found out he'd ratted them out and fired him. I have little respect for the FAA anymore.

[@maxineamon]

@@recoilrob324 what wasn't made clear in your narrative is that the crash happened in 2000. Meaning the FAA had plenty of warning that it was likely an accident was in the making. They need to be sued for negligence. Obviously the mechanic thought they were the authority to deal with it but he wasn't informed by them that they weren't. Had he known this he could have gone down a different path. Perhaps talking to the media.

[@lobsterbark]

@@recoilrob324 I think the FAA is highly aware of the fact that if they stepped on too many toes with deep pockets, Congress would likely reduce their regulatory power. I don't know if that makes being soft in Alaska airlines in this case the right call, but I think it's a factor in their decision making.

[@carlwilliams6977]

This brings up a point I've always wondered about. When one of the pilots is doing the walk around, why don't they have the other pilot actually operate the controls, to see that they're actually doing what they're being asked to do? This seems even more relevant, given fly by wire systems. The walk around pilot could simply carry a handheld radio, to communicate with the cockpit.

[@PPiero63]

yes, that's a really good question.

[@realulli]

Wouldn't have helped. Mentour Pilot explained rather close to the beginning of the video that it it quite normal for the elevator halves to be pointing in two different directions when parked. During the workaround, the pilot doing the walkaround would have seen the control tab move as expected, the main elevator wouldn't have moved due to lack of airflow. Nothing to see here, move along...

[@carlwilliams6977]

@@realulli That's not true. One of the trim tabs had been overextended while parked, placing it in a locked position. The walk around pilot couldn't see that it wasn't in the same position as the other trim tab, because he was 30 ft below it. Had he expected it to move, he would have seen that both trim tabs were not moving in unison, and that something was wrong. That would have been obvious, even from 30 ft below.

[@TheScreamingFrog916]

@@carlwilliams6977 I think what you are missing is that, without air flowing over the elevators, they won't move, and that the jammed part is not directly controlled by the pilots control stick. That is why the NTSB recommended a new procedure be implemented, for checking that system, during the preflight checks.

[@carlwilliams6977]

@@TheScreamingFrog9168:00 I fully understand that the elevators wouldn't move without airflow, (because there's no resistance on the tabs). However, the geared tabs and control tabs would move. One of the gear tabs was locked in the up position, due to overextension during high winds when the aircraft was parked. When the pilot pulled back on the stick during takeoff, that tab did not respond, because it was locked. If the geared tab doesn't move, it's not going to move the elevator. The walk around pilot could have seen that the gear tab wasn't moving if he asked the pilot in the cockpit to make it move. During takeoff, the tabs have to move down, so that the elevators move up, thereby lifting the nose of the plane. No tab movement, no elevator movement, no takeoff! If the control tabs and geared tabs aren't controlled by the stick, how are they activated?

I do much appreciate your ability to explain these technical problems in ways I can understand. Although I'm not a pilot and have no aspirations to ever be one, I have a curious mind and enjoy just learning exactly how things work and how skilled people react to crises. My history is as an intensive care nurse and there are subtle similarities in these situations: knowledge of how things work (bodies vs planes), respond to interventions, critical thinking skills, ( hey, what's really going on here?) and very timely actions. I will say this: the times involved with reacting rapidly are usually very much shorter ( seconds vs. minutes) than in most medical situations , but I've had situations where seconds actually DID count ( HEY!, this guy is going to code! Do this NOW!) And in medical situations the abilities of your team (crew) to respond quickly in appropriate ways also makes a big difference. The other main, HUGE difference is that my actions would only ever affect the lives of only my one patient and their family, not the entire passenger list and crew of a plane. I can't imagine being responsible for THAT! I'm not likening myself to an airline pilot; please don't misunderstand! I've just been trying to understand exactly why I am so very drawn to and enjoy learning about these situations, how they are managed or mismanaged and what led up to anomalies.

Wind is an incredible force and where I live (Wyoming USA) is a force we deal with pretty much every day, but becomes deadly in winters. You learn to determine what the wind is creating around buildings or natural barriers by looking at snow drifting. I figured out as soon as I put the wind/plane parked situation together with the understanding of the gear tab right away. Gotta love physics!

[@OfficialSamuelC]

This also shows how pilots have honed in their senses to know when their airplane doesn’t feel normal. That kind of recognition and response has to be second nature and there isn’t any time to consciously think it over in time. I’m thankful that pilots know their aircraft so well and know almost instantly when the slightest flight control behaviour or even sounds, don’t feel or sound right. Kudos to both of them, especially the pilot monitoring. It would’ve been interesting to know what the pilot monitoring would’ve done had been pilot flying, but we can’t judge him as he will never feel what the pilot flying was feeling in that moment. It’s easy to say don’t abort when you can’t feel the aircraft, but I have faith that the pilot monitoring would’ve done the same had he been the one to take off. His CRM and discipline shows that he’s likely more than capable of recognising and actioning any issues that arise. I wonder if there’s training for aborting take offs after V1 in simulation scenarios where there is a flight control issue where the nose isn’t rising or something isn’t feeling right. It’s the kind of issue you want pilots to be able to know and react instantly because a second or few thinking about it could be the difference between going off the runway somewhat controlled, or barrelling off the end and continuing into you hit something or crash with more force. I guess these scenarios are hard if not impossible to train for and you have hope that if you’re ever in that situation that you recognise it and respond immediately. Bravo to both pilots.

Amazing work by the Captain in command! There are far too many videos where the pilots get frozen up when things don't go as planned, leading to a critical delay that causes far greater catastrophe. He responded decisively what to do within a couple seconds, and announced that intention clearly to his First Officer before immediately proceeding. Absolutely stellar performance! Had he kept trying to lift off this would have ended terribly. If they got fast enough, the plane may have tried to roll with one pushing down and one pushing up. And even if it didn't tip over, every second adding speed would have caused great devastation when hitting the tree line after the runaway zone. Kudos to the Captain. And kudos to the First Officer for not actually taking over command of the controls. There are a lot of pilots out there that would have panicked and done something very counter-productive in that situation, working against each other.

I live in Ann Arbor (just down the road from Willow Run), and as such, I got a special kick out of this episode--and from hearing Mentour Pilot repeatedly mention my Wolverines and their good judgment ;) But also, I well remember this incident but had never heard the fascinating info described here. Indeed, if I understand correctly, had the flight crew not made a choice that their training essentially contradicted, this might have been a major tragedy involving loss of life. Thanks for telling this story, and as usual, great video!

[@MentourPilot]

That’s correct! Glad you liked it!

[@johnopalko5223]

@@lizlovsdagmara5525 The funny thing is, I'm not a Wolverine. I went to the University of Illinois. I was in the Varsity Men's Glee Club and our signature song, with which we ended every concert, was the "Big Ten Medley." So, I learned all the Big Ten fight songs, or, at least, the baritone lines.

Fantastic video as always! Having flown the DC-9/MD-80 as a passenger many times back in the day with Scandinavian Airlines, I had no idea that the flight controls didn't directly control the elevators... fascinating, and amazing work by the pilots in preventing what surely would have been a tragedy if the takeoff hadn't been rejected.

[@MentourPilot]

Indeed! It was really fascinating to research as well

[@joakimlindblom8256]

@@MentourPilot Yes -- I'm always interest in learning about creative (and often counterintuitive) engineering designs. I always had a soft spot for the DC-9/MD-80: with engines in the back making for a very quiet ride with a typically steep takeoff climb, it felt like a combination rocket ship and magic carpet ride into the sky ;-)

[@DanielinLaTuna]

Always an excellent synopsis and explanation of the events and actions. I have recommended select episodes to my pilot friends and relatives.

[@mariebaumbach7345]

so many things coming together in these videos for me: my love for physics, my love for (necessarily) strict rules and regulations, and the true crime feel the investigations have 😍😍😍 I'm addicted

[@tommytfaa]

Me too he is such a great story teller

[@mgscheue]

Yes! I'm not a pilot (except for my little drone) but I love aviation and teach physics. These videos are so great.

[@alshotrodsandratrods8780]

My first thought was why didn't they put a stop to prevent the geared tab from going past the point where it jammed. Then you said that's what they did to prevent it happening again. I still wonder why they didn't do it when they designed the plane.

[@MentourPilot]

There was some kind of stop but not designed to withstand those type of forces.

[@moestrei]

No brainer, you would think. So easy to implement. My respect for Boeing engineering dropping even further.

[@RoamMeYo]

@@moestrei not really, as adding more material will increase the weight and also costs more, so unless it is a must have they will try to optimise the design. Happens in all industries, not just aviation, of course aviation needs extra attention. Glad that they rectified after an incident at the least.

[@pcdispatch]

@@RoamMeYo , but Boeing could have fixed the flaw directly when the problem was detected. They didn't.

[@bobvicki]

@@moestrei But, this system was designed by Douglas Aircraft in the mid '60s & operated trouble free for 30 yrs before Boeing bought the company & then another 20 yrs before this accident occurred. When a potential problem became evident, Boeing engineering implemented a fix.

[@pieterdebie4162]

Once again: great video and props to the captains.

[@TheraPi]

I had no idea, the tail control surfaces on that model were of such an intricate design... A control tab going down indirectly moves the actual elevator surface up, and the geared tab serving as a force amplifier.... what could possibly go wrong :D

[@johnstreet819]

Well, if the seals in the knudlin valve failed and the krimizin fluid leaked all over the zimelich the whole tail could fall off.

[@thewhitefalcon8539]

@@johnstreet819 This kinda happened in United 232. That krimizin fluid is important! Without the flying juice you can't fly.

[@donaldallen1771]

Absolutely crazy design, since the proper operation of the control surface can't be verified from the cockpit or anywhere else. So as these (great) pilots discovered, you don't get to know whether you have pitch control until you try to rotate. I wonder if this different elevator actuation on the MD-83 was the result of the Alaska Airlines DC-9 failed jackscrew crash.

[@Bred0nSch00lV2]

This has happened to other aircraft including Air Moorea Flight 1121. It was much smaller than this MD plane though.

[@lisawillis1233]

What I love is how thorough the investigation is, with the goal of truly understanding what happened in order to consistently make flying safer. Drones? Wind models? So cool.

[@jazzman5598]

I LOVE these vids of awesome pilots doing “Sully Level” outside the box thinking. Many would be completely unknown without vids from pilots with experience levels like yours. Thank you.
