- In this video we are looking at an accident that occurred in late 2017. This is the first part in what will be a three-part series.
In the first part here, we will simply look at the the video footage that accompanies the accident. In the second part we will do and in-depth analysis of the engine failure. And in the third part, we will tie everything together and look into the flight portion of the accident. This aircraft involved was a Quicksilver GT500 with a Rotax 582 liquid cooled 65 hp engine. Onboard the aircraft is the student pilot and his flight instructor. This flight was the third leg of a cross-country flight. The first leg of the cross-country flight was from Corning to Orville California. The second leg of the flight was from Orville to Willows California. - Навчання та стиль
“What the hell happened?” You had five seconds of your engine power decreasing and during that time even as it quit running completely, you continued to pull back on the yoke instead of pushing it forward to maintain your airspeed. You stalled it in from at least 20 feet in the air. Not once did you push the yoke forward to try and keep a good airspeed for a landing. That’s what happened.
Great example of aviation's greatest saying: "Want to go up? Pull back. Want to come down? Pull back some more."
As soon as the engine cut out, he should have pushed the nose down to keep up airspeed, instead, he pulled the stick back, causing a nose down stall and rapid rate of decent. Ouch!
So, I started by flying in towed gliders, and we practiced "rope breaks." Stick should go forward immediately to keep airspeed up and AOA low to prevent a stall. I've never flow this airplane, but if it has a high thrust line like many ultralights, losing engine power may cause the nose to rise, making it all worse. And a student low to the ground wants his airplane to go up, so pulls back by instinct. If this had dual controls, the instructor could have taken over. But this is just my Monday morning quarterbacking, so could be deeply flawed. Many thanks for posting -- this is how safety is made. Looking forward to the next videos.
SteveandLizDonaldson Exactly how I was trained too...Lose power, stick immediately forward, to prevent stall
SteveandLizDonaldson
Can't stall at zero gee.
I also started flying in sailplanes at CA CITY, CA.....Grob 103.....watching this video appears that engine quit, plane loses altitude as pilot continues pulling back on stick.....
Really thanks for sharing this footage, noble consideration for instructor and student. Very good lessons learned.
Someone wasn't paying attention to the tach. plenty of runway left for a dead stick landing. Too bad, if you have enough airspeed to pull it of the ground you had enough airspeed to put it back down. Bet the pilot will never pull back on the yoke for an engine failure like this one again.
I’m glad he say they managed to walk away from the crash.
From the sound of the engine, it sounds like a typical classic Rotax engine seizure… Most likely caused either by not letting the engine come up to operating temperature before attempting take off, or from lack of oil. I have actually witnessed something like this happening with a Quicksilver many years ago.

Thank you for sharing
Oh, and BTW...thanks for sharing this! It takes stones to show your less than stellar moments.
You're right. The owner was very reluctant at first. But I think my offer to go retrieve the airplane and do the engine teardown analysis for free if he let me use the video swayed his decision. The more important aspect is being able to use the video in conjunction with the engine teardown and the flight analysis for training purposes to keep others from suffering the same fate.
Engines fail, but pulling the stick into your lap fifty feet over the runway is not ever a good idea. That would have gone just as badly or worse in a heavier aircraft.
On the edge of my seat now waiting to learn what caused the stoppage. Thanks for uploading.
You won't be disappointed. We have about a 120 hours of analysis into the engine failure that we provided to the NTSB.
I've also had a lot of engine failures with the 582. The only two stroke that seems reliable enough for my tastes is the rotax 503
He had that stick all the way back ...... he doesn’t know what the hell he is doing.
Thank you for sharing the footage. Good they were not higher ending in a more perpendicular impact. When the motor goes gunny, need the stick forward and acquire a glide path to the best spot. In this case lots of runway. Very sorry that happened, however, glad they walked a way.
So I probably missed this and it is more of a question. Did they run the engine up and down a few times before taking off?
You can see in the video he never pushed the stick forward when the engine quit, he kept holding it in the same position until the aircraft lost speed and stalled he should have pushed the nose down slightly to keep the air speed.
why is part of the plane blurred? is there a licence plate there?
though I'm leaning towards fuel starvation. not quite sure if I seen him perform any mag checks
When will part 2 be available?
Thanks for the vid! Glad you guys are ok...ARE you?
Where are the other parts?
Chas
Things have been in emergency response mode since the big break in, in Hanger 7. We were recently able to replace some of our computer and video equipment that was stolen. It will probably be a few months before we are back on our feet.
Is part 2 ever coming???
Forgot to turn the fuel on?
Well that seems like it was easily avoidable. Do you not have to have a PPL to fly that?
No MAG check?
Cold seizure, I am looking forward to next video
I would have to agree that you are correct. Very unfortunate for the plane but at least they can still go home to their families.
Nice use of the centerline :-)
During take off when he was running - it was clear heard that r582 is not giving full power. At the same time he started take off procedure and did not realize this. In order to prevent such case we make better pre-heating of engine before take off and giving max rpm to it for test on the ground. If it works well than take off. There was no 65hp during take off, the engine was like getting much more fuel than should...
No dead stick landing training?
First off, whoever was flying allowed themselves to get immediately blown of centerline. This shows inexperience.
Secondly, the nose should go down after engine cut off, which it did but there was no flare before touchdown. Just straight into the ground. What the hell? Looks like somebody panicked and froze.
Did it stall?
It stalled out when the engine cut because the way the plane is built, the engine has a high Center of Mass and it sits near the rear of the plane, the wings sit INFRONT of the engine and thus when it cut out it caused the back of the aircraft to drop before the nose, and it stalled the aircraft out causing it to plummet to the ground.
@@JustAGooseman Naw. Watch what the pilot does with the stick. It needs to go forward, immediately.
@@UncleKennysPlace Correct, you can see the airspeed decrease. He needed a quick and substantial forward stick action. My instructor pulled power at a similar altitude when I was training on my Challenger 2, which has the engine in a similar location. I reacted correctly and set her down.
what was the air temp at the time of take off? not enough heat in engine (cold seize) and instructor should have taken control.
instead of stalling 10' above the runway. when all else fails "fly the aircraft"
Navy teaches. Aviate-naivgate-communicate. I think that is how the Navy spells.
Doesn't this plane have a very narrow window between vr1 and stall speed. Vr1 is 50 mph and stall is 40? Seems I remember that from somewhere. Not too much of a window of error.
First guess...lack of fuel. I saw plenty in the tanks, but was it reaching the engine?
engine tapered off like you would think it would from fuel starvation ???
@@P40BTomahawk Sounded more like a mechanical failure. Not in the crank or conrods. It tried to burn, so there was air, spark and fuel in the cylinders. Piston rings?
Interesting that the stick required back pressure to rotate. Normally the pilot may pull back some to rotate, in a well balanced plane you need to go to more neutral elevator position. The instructor must take control in an emergency, the instructor should have shoved the yoke full forward.
Wish we could see the engine instruments prior to takeoff. The engine sounds rough to me, during engine idle and while taxing. Looks like the airplane stalled to me. I saw no forward stick, once the engine started to stop. I am sure that if he had kept his airspeed up, after the engine quit, he would have had enough airspeed to glide, flair and make a landing with no damage to the airframe. Did he exceed the critical angle of attack? Perhaps, if he had an AOA indicator, it would have made this pilot more aware of the aircraft, about to stall. Thanks again Brian for the video.
You can fly without motors, but not without knowledge AND SKILLS. Orville Wright, 1911.
At first I was gonna say he didn't flare, but it appears he tried to flare, but airspeed was too low.
So what happened to parts two and three?
Things have been in emergency response mode since the big break in, in Hanger 7. We were recently able to replace some of our computer and video equipment that was stolen. It will probably be a few months before we are back on our feet.
A perfect example of what not to do when you lose power, when the engine quits instead of pushing the nose down he sucks the stick as far back as it would go, violating the most basic operating procedure. Engine quitting started the chain of events, but it was pilot error that caused the crash. Was the instructor asleep when this happened?
That engine gave PLENTY advanced warning that it was going to quit...the second it started losing power he should have decreased pitch. With these two strokes you have to warm them up a lot more thoroughly than this guy did....4 minutes is NOT enough. And you have to warm it up at much higher rpm than he did....you need the engine casing/cylinders to be full running temp....not just the cylinder heads and EGT. I do the last part of my 7 minute warmup at over 4000 rpm.
The moment the engine fails - STICK FORWARD to maintain flying speed. Similar to glider winch cable break. Get the nose down instantly, then gently flare. Never hold the stick back, hoping the wings will defy gravity.
Man, glad they made it out. That was a decent hit.
They were so low I would be hesitant to push the stick forward too. Seems like it would just speed you are o the ground. It's counter intuitive.
I am glad everyone is now OK. what a terrible place to have a complete engine failure!
"What a terrible place"????? Over a runway is the ideal place !!!!! A terrible place is over downtown New York, a densely populated residential area, North Korea OR alligator infested swamps. Over a runway..with sufficient altitude for recovery...come on. You can't ask for a better place. The so called "instructor" should hang up any thoughts of calling him/herself an instructor. That was a perfect teaching moment.....totally blown. There's way more to this incident
Good Answer. I saw a video of a crash on everglades with a photo of gators knawing at the pilot still on his seat. It looked like he stalled it. In a stall and sudden stop, your spine can compress, and you cannot move at all. Gators meal.
ok, so i never got a notification of a reply. you are right, there are worse places, but being an extra 2000 feet would have been even better. but i wouldn't know what it is like for light aircraft, i have only ever had a few hours on powered gliders, where we were always taught that engine failure after take-off was one of the worse things that could happen to us.
Sounds like a seizure maybe from the lack of oil or fuel
Dude rotates full up before even gets off the ground. What rate of climb was he thinking of doing in an ultra light??? I don't think he even knew the engine cut out as he kept trying to pull up to maintain his 500 feet per. Sec. climb rate. Glad they got to walk away from it.
blockage in the fuel line. Most likely an unclean fuel filter.
Power cuts out. Lots of runway. Let’s pull the stick back as hard as I can and see what happens. Least they are ok.
I'm not a pilot, I'd like to get a public opinion out on this one. To me it is obvious that upon engine stop, the controls are continuously held at the same position as rotation. When that engine stopped, others noted the nose went down, IMO that was NOT pilot induced, rather gravity induced. The pilot could have immediately moved the controls forward and exacerbated descent and made an effort to soften with control input. Alternatively, just let go of the sticks completely might have fared a little better than what he ended up with since. My guess is unloading the control surfaces the airplane would glide better. But he loaded that thing all the way into the ground. Glad he lived to agree to share. I'm sure he realized the mistake the moment he hit the ground.
What was the cause of engine failure?
We will be sharing the cause of the engine failure in part two. It's looking like right now that whole video is going to be nearly an hour long. We don't want to spoil the results for all of those that are taking the poll and are participating in the analysis. About thirty days and will release the part to video.
Where is the poll?
In the upper right-hand screen on the video there is a little circle with an "i" in the center. Click that and it will give you the most recent results as well as allow you to cast your vote.
You have to nose it over to get air speed , this guy kept pulling up ? Fuel wasn’t on .

He did not push on the stick, as soon the engine quits
Crash was caused by pilot error. No power does not mean pull the yoke back. First rule in engie loss, best glide speed. Should have changed to nose down attitude immediately. Instead he induced a stall. Engine was a very minor factor, and since startup you can hear the engine running like crap.
That was a very very slow engine failure.
parts 2 and 3 coming?
Things have been in emergency response mode since the big break in, in Hanger 7. We were recently able to replace some of our computer and video equipment that was stolen. It will probably be a few months before we are back on our feet.
Ohh. I guess I didn't realize there had been THAT kinda complications.
That's one tough dude. "I think I broke my back, but that's okay".
Looked like a stall just a few feet off the ground. Not much time to react that’s for sure.
Not true. When the engine dies on take-off it should take less that .5 seconds to stuff that nose forward to gain another 10 mph airspeed for a proper flare.
Hello, the video speaks for itself. The quicksilver is not what is best in aerodynamics, the badin decreases very quickly in case of engine failure, especially the rear sector handle .. Note that the driver does not stop to bring the joystick up. There is distance in front, no stree, it was enough to put the handle forward, to keep the speed, and everything was ok :-( In any case, thank you for sharing this video that can serve as example of what not to do in case of engine failure.Good courage for the repair of the machine. Thanks to Google translate ;-)
Wow. He didn’t pull up at all. That was totallly landable.
I watched again. I’m mistaken. The weight and balance is was off on this.
As soon as he lost power he was pulling back on the stick a big no no.. like many others saying stick forward recover airspeed.I know not a real lot of height but would of saved the aircraft I think.
You can distintly hear someone screaming out (in distress) the word "shit!!" at 6:18, 6:43, 6:50, and 7:03. Creepy!
The brakes have Tourette's Syndrome.
It's the brakes lol
Rich oil carb adjust
After listening - I'm guessing that relationship went south afterward !
He should have practiced more engine failures on take off
He forced the plane into taking off instead of letting it attain enough air speed to lift off the ground. Now the engine quits without enough air speed for the elevator controls and now you’re a rock.
So who was flying? the student or instructor? I can't imagine an instructor making such an amateur mistake!
We will address all of this in part 3
Buzz Shannon you'd be surprise!!
When is part 3 coming?
Depends on the CFI. Many CFI's I taught that maneuver could not push the nose down to glide. They panic too.
Looked like a sudden seizure,no warning.
Someone didn't fly gliders before
Best line - "I broke my back but that's Ok".
Not sure why the engine quit, but your CG is why you got hurt. See how much backforce you needed just to rotate?! Only way out after engine failure would’ve been a radical pushover (to low), to gain as much airspeed you could obtain, for the flare. At least y’all walked away relatively unscathed
The problem is this guy we can see (I understand one was student other was instructor), loses the engine and still keeps pulling on the stick. He's stalled. It's about airspeed, means drop the nose, oh look at all that remaining runway, land, no problem. This was pilot error. Odd because one of those two was the "instructor" I hope it wasn't the guy we see pulling on the stick while stalled 20 feet in the air. Glad no one was hurt and I'd recommend some flight training for the both of them.
We will discuss in part 4.
Pilot error. Didn't shove the yoke forward immediately. started losing power at rotation but no pilot input. Probably had the fuel valve off or on a dry tank. I have 10,000+ hours in Quicksilvers.
Takeoff @ 7:30 time stamp...
Let me guess. Vapor lock.
They should have done an engine full throttle test before takeoff. I hate does kind off engine s I rather have a turboprop engine on the plane
Another possibility could be pre-ignition/detonation.
Thats cheating, I'll bet you read our latest Sport Aviation Magazine Article.
LOL!!!!!!! Guilty as charged! Sorry Brian. Hey, at least I read your article though.... Hahaha
May I suggest a run up before you take off in the future, sir? And maybe get the nose down if it occurs again, rather than yanking the stick back.
The engine almost sounded like the ignition was turned off, no stuttering or missing. A cold seizure is a distinct possibility as is lack of the proper amount of 2 Stroke oil in the mixture. The crash resulted from the pilot attempting to climb instead of leveling off when the engine failed, which resulted in a stall and the crash.
Nose down he held it until it stalled
He had to push the nose over but he didn't he panicked
Push stick down for airspeed to land without stalling. Don't have to watch rest of videos. Have done many engine out landings and stalls. Thank God they were all right.
Not About Engine Failure - Engines Fail Every Day All Around The World ... What Matters MOST Is What What Happened After
Tremendous footage. My money is on a fuel supply cutting out.
omg, you dont have enought power = you push on your stick !!
After engine failure there was too low high that is why instinctly pilot was making not right actions and continue to loose speed. Fortunately they were close to ground. I have seen such pilot behavior even with thousands of hours in portfolio.
Testament to the aircraft that it didn't drop a wing when stalled ! Could have been much worse if you landed at a angle.
very slouly crash engine oh my god very very fortunated the man pilot in the air plane w the fly and human progress in the world
Lesson learned, don't stall your airplane.
I think my back is broken but that's OK, Ahahahahahaha!
That was not a "pilot" flying that aircraft. An actual pilot would have stuffed that nose down immediately upon power loss. I'm talking a minimum of 30-40 degrees below the horizon for such a draggy airframe. He needed to increase his airspeed to one which will allow some kind of flare just before touchdown. He obviously never once practiced engine failures upon take-off. So he ran out of energy and smacked her on in! When I practice engine failures in my Hurricane during takeoff, I have to stuff the nose down right away, and I mean immediately once I pull the power! Loss of power should be followed instantaneously by shoving that elevator control to the firewall to maintain airspeed. 100% pilot error. That crash had nothing to do with the engine failure with all that runway below him! I don't care if the engine fails at 2ft, 20ft, 200ft, or 2000ft. If you are over 200ft, you can get away with trimming the plane for best glide, but when you get close to the ground, you better drop that nose a little to pick up airspeed or she will pancake in!
Hey stop flying airplane I fly Glider He should’ve just landed straight ahead but it look like he was pulling the stick back
8:00 RPM starts to drop the nose starts to fall some what does the PIC do pull back more on that yoke he can't figure out why it won't go up even has the engine is almost silent. As the ground starts to rise below him he pulls the yoke back all the way to his chest still hoping it will somehow magically go up. How in the heck did this guy get signed off to even solo his instructor should have his license revoked. My guess lot of these guys flying out there who were poor students but Poor CFI's who making 20k a year sign them off anyway. 8:20 "What happened" response "I don't know" the pilot says. app.ntsb.gov/pdfgenerator/ReportGeneratorFile.ashx?EventID=20171125X91028&AKey=1&RType=HTML&IType=LA Interesting the NTSB report says no injury's sounds like there was.
I disagree. It’s not that the stick didn’t go forwards, it only ever went backwards. So the problem was the pilots’s (in)reaction in dealing with falling airspeed. Engines fail. The backstop is the pilot. This should have just been an inconvenience. I’m glad nobody was killed.
Solo de ver este vídeo , te das cuenta q el piloto huso todo lo q no tenía q hacer , halo el yoje y entro en un stall y el instructor estaba dormido o se asustó también, hay personas q ni nacen para esto si hubieran estado a 150 pies se hubieran matado con el impacto , dios los cuide
No attempt to maintain flying speed. Stick back all the way.
I think my back is broken, but that's ok.
Why is it that every time I watch an ultralight engine failure the pilot pulls back on the stick. Could it be the lack of formal training. Maybe they want to stall to add to the excitement. This crash could have easily been avoided if the pilot had pushed the stick forward and maintained his airspeed. The guys that fly ultralights are the most macho bunch of pilots out there thinking that just because they don't need a license they dont need to take lessons. I feel bad for the passenger and his back.
The real failure here is that EAA stop building primary gliders and letting people learn to fly in them, and instead focused on building fast, tin can metal airplanes. Because primary gliders aren't sexy. Learn in a glider like you are suppose to, and every landing is a dead stick landing, there is nothing out of the ordinary about landing without power.
Fix your airplane, and land 50 times in a row with no power at all, and not just on the runway. All over the place. Farmers fields, backyards, strip mines, soccer fields, river banks, everywhere. When you can do that, then you are ready to fly again over any terrain everywhere. :)
I ve had 3 engine failures in 3 different ultalights and i can tell u the 1st time it happened i did exacltly what this guy did . Only i was alone so the sink rate wasn t so outrageous and it ended up as a hard landing only. Then next 2 were not so much of a surprise. Didn t even ding an aeroplane. All rotex engines btw
Este chico no esta preparado para un solo flight, no calentó el motor lo suficiente, y se a susto y nunca bajo la nariz para mantener el avión volando! Hubiese estado 150 pies se hubiesen matado los dos!
The all too Common "Pilot Panic Pull".
Stalled the plane because they refused to scenario-practice deadsticks..... Airspeed, Airspeed, Airspeed, That aircraft could have been landed........
