- US Air Dash 8-300 Inflight Engine Failure just after takeoff. The #1 engine started surging and as a precautionary measure the captain shut it down and we returned safely to the airport.A news crew was at the airport on another story and filmed the landing. You can see it here at this link • Plane Lands On 1 Engin...
This link has been updated and it works.
Not an engine failure, a precautionary shut down. I had the same thing happen to me a few months ago. It was the beta lock out switch which was unserviceable. This surging was the prop going in and out of feather. The beta lock out is designed to stop the pilot over speeding the prop by accidentally pulling the power levers back behind the gate, which could send the props into a huge over speed. It's happened in the past with the loss of the aircraft and pax/crew. That's when they fitted this back up. You'd have noticed it only started surging once the gear was up and locked. That's because there is a switch, (pseu) that tells the beta system it's in an inflight condition. The AFM now tells you to pull the fuel condition levers back to 900 rpm, (performance permitting), and cycling goes away. It certainly gets your attention though!
+Mark S Hi Mark, what Jarv said is absolutely correct, you can hear the surging at the exact same time as the gear starts to retract, although the pseu switch he mentions senses an inflight condition upon the start of the retraction of the gear - not the actual stowage. It's at the same time the brakes are automatically applied to the wheels to arrest their spinning before stowage. The fact that he knows all about the beta lockout system on Q300's should tell you that he is a pilot though.
So what flight sim do you use.....
thats exactly an engine failure. beta lock out or not, if its not performing as it should = its an engine failure.
@@haitiano1982 precautionary shut down. it would continue to run if you didn't do anything, With an engine failure, you don't get a choice.
Fue justo cuando se replegó el tren de aterrizaje que el motor 1 (izquierdo) se detuvo. Creo que intentaron volverlo a poner en marcha varias veces, hasta que preventivamente decidieron regresar al aeropuerto de origen
So, I googled to see what a Dash 8 looks like since I will be flying on one of these soon and I come up with this video. Nice to see it lands on one engine but I prefer both engines work on my flight.
Your flight will be fine. ALL your flights will be fine and end well!
Hahaha. That is a good one.
I just found this in my recommended videos. Gone are the days of US Air :/
We lost one engine I believe from Exeter- Amsterdam it flew fine all the way back to Southampton UK
All modern multi engine planes can take off and land just fine with one inoperative engine
I was departing from Greensboro, NC. The only explanation we heard was what the Captain said on the video, "a slight abnormality"
Thanks for watching!
Some people feel unsafe on small turboprops, but I feel more safe. They can fly and land on one engine and if both go out.....well, a dash 8 could land in an empty Costco parking lot if it needed to.
All planes glide. It needs more than a parking lot I assure you.
With reverse thrust from 2 working engines, sure.. It can land and come to a stop pretty quickly
With one engine out the stopping distance increases, with no engines.. it takes many, many times farther to stop
DJ Dash 8s don't have reverse thrust, as well as ATRs.
Aircraft can fly with one engien
American 015 they do have reverse thrust. They reverse the pitch of the propellers.
No need to clap when you are in a Dash 8... Only for joy... ;)
This rugged machines are awesome!
Rui Raposo I like them. They ride good. With the high wing, the view is excellent. And anything made by the people who made the Beaver and Otter is OK with me.
and the Mosquito of course. Not made of the same people but made by the deHavilland.
Props to the pilot who identified the situation, and acted accordingly. The only thing negative I can see in this video, is the passengers not clapping when the pilot landed after identifying on board engine failure!
Great Video! Glad everyone is A-OK!
notice how calm the pilots are - no sense of panic at all...no wonder they're one of the most highly trained professionals in the world...and what's amazing is that despite their salaries, these individuals choose PASSION over MONEY = at-most respect :)
I used to work on the dash 8s for America West and us airways. I hate when people don't listen to turn off electronic devices.
Their electronic systems must be incredibly sensitive to mobile phone frequency harmonics then. Afaik there wasn't any successful proof that mobile phones actually intefere with aircraft electronic systems, perhaps a passenger had some sort of jammer or everyone making a call simultaneously (which isn't large for modern phones) or some other high-energy wave creating method.
In fact: Most European Airlines allow you to let your devices powered on. Apart from draining your battery, there is nothing to it.
You may forget there is another reason. 1. Just an unnecessary additional risk. 2. On some airplanes, when passengerns have there cell phones in normal mode you can hear the phones searching for network in the radio or headset of the airplane as a continues rattling sound. This not only just extremly annoying but also an additional risk and can cause to not beeing able to listen to the controllers or other airplanes carefully. You do not neccesarily crash of that single reason of course. But think of the Teneriffe accident which was as well caused by issues to understand each other on the radio (cause of a different reason, sure). They did a lot things wrong of course but the last line of defense was the communication. And this one failed. So interfering sounds in the radio may be the straw the break the camel´s back.
AdventureAirInc You do know, that the communications array of every plane (even a small cessna) is shielded against all radiation, except those in that narrow FM-Band? You can't compare that to your speakers on your desk...
+NFreund Not sufficient shielded for this. Cause it was not a part of the FAAs certification requirements. I know, cause I'm flying all these birds from a cessna up to larger ones. I experienced these issues and a lot of my colleagues as well.
@weatherscience Engine is windmilling a little bit, but this is probably just because of some light sideward motion of the wind. A Turbine engine is really easy to move around. The engine blades are in feathered position so they don't start to windmill (windmilling produces drag). Normally you don't try to restart your engine unless you lose both engine, the engine didn't stop/was shut down for nothing ;)
Loss of an engine on take-off is the absolute worst case scenario in a twin engine aircraft, and almost always results in a crash with piston-engined aircraft. This pilot's skill combined with the power of the turboprop engines saved this flight....
Flew a lot of times from Williamsburg-Newport News VA when at US ARMY Aviation Logistic School FT Eustis twice. Only once made an emergency landing at Richmond Airport and we're picked up and taken to Newport News by the US Airways.
im from norway and we use the dash 8, the engines never fails
That’s a perfect landing with one available engine
what a perfect landing! exactly at the touch-down point, with just one engine running and smooth just like a kiss..hell yeah
That's why maintaining an aircraft before a flight is a priority. Problems like these, don't happen very often in an aviation industry but it is no excuse.
My father experienced the same thing many years ago when he was flying on a commuter plane (it might have been a Dash 8 or an ATR). Thankfully, they landed safely. Great pilots!!
I recall some Danish students making a sort of game about such airplanes having engines falling off - all in Danish. Not online now.
Engine probably was completely failed. The surging that can be heard and was mentioned was the NTS (negative torque sensing) system. This prevents the prop from going to flat pitch with loss of torque, which would be disastrous. Just because prop is still turning does not mean the engine is still running or producting thrust.
The directional gyros are not affected by any magnetic field because of AHRS. Also, ipods and cellphones do not emit any radioactive or magnetic field as they are solid state devices. Even if they did, it wouldnt make sense to prohibit them just on takeoff and landing. The compass would be no more susceptible to the field on takeoff than it would be in cruise. They dont want you using them so that you maintain a sterile cabin environment in the event of an evacuation or emergency.
How about a hand for the flight crew?
how about a head from cabin crew? ;)))
Yer ass is suckin' swamp water!
Funny enough, at my local airport (Birmingham UK). One time the plane (a Q400) nearly crashed wings almost hitting runway because the pilots hand fell off on landing.
They had a beta lockout failure. It was prop RPM surging, not turbine RPM. The procedure is to reduce prop RPM to 900, but this crew had some other indications the issue might have been more involved, hence the shut down.
Dash 8's are great aircraft. It behaves the same on one engine. To those that think the electronic device caused the engine failure I can say impossible. The p/w 123 engines don't have anything fancy to run them. There is a computer but it has a manual mode which shuts the computer off. Computer is there only to adjust fuel scheduling to compensate for different altitudes and to sync engines together for smoother running. Most likely pilots got a indication that oil pressure was low and shut do
Thats whats awesome about a twin engine. If one goes down you still have the other. Losing it on takeoff is a little hard because the plane wants to yaw because of all the torque of just one engine on one side of the plane.
we practice all types of emergencies including engine failures quite often and that also includes the passenger briefing (even though there are no passengers when this is done)...
to be honest though a single engine failure really is no need for concern. When you lose all engines or have a structural failure is when your blood pressure should increase!
In this one, it's the port engine that's failing. Usually, it's the starboard engine that's most likely to fail, because the starboard engine gets the most wear and tear. The starboard engine is almost always fired up before the port engine. If I had a twin engine aircraft of my very own, I would for one flight fire up the port engine and then the starboard engine. It would be vice versa for the next flight. If I wanted to taxi on one engine to save fuel, I would follow the "POSH" rule, "port out, starboard home". That means I would use the port engine to move from terminal or hanger to runway, and then use the starboard engine to move from runway to terminal or hanger. That way, the engines would wear evenly, and could be serviced simultaneously.
My stepmother worked at de Havilland. She used to pop rivet the wing assemblies on the Dash 8s .
Was surprise that the flight deck crew did not notice a problem with #1 (via the gauges or the "sound & vibrations, etc), as they accelerated towards "V1". The guy with the camera certainly showed that there was a problem, with that engine, early on. Just surprised me. Great return to the airfield with an exquisite landing, considering the circumstances. Not critizing, just curious about what the crew was "experiencing", during their initial roll. Thanks.
After reviewing the video, you are absolutely correct - there doesn't appear to be a problem, as viewed through the guy's camera prior to acceleration. What I was "fooled" by (should know better :-) was the motion of the prop blades, which is really a feature caused by the video recording. "One" can't be right all the time, can "one". :-) Thanks, N-6395T
actually the props are windmilling because you can never have a true 0 angle to the wind. the blades are slightly twisted for aerodynamic reasons. because of that they still windmill. the turbine that spins the prop is so far back wind wont reach it. not too mention then you have to spin the whole prop reduction system
@killbilly069 making an analogy. gas turbines have surges. loosing an engine from surges does not mean anything is broken inside. vapor lock is still a posibility. statistics are per passenger mile not per that their are less vehicles . I'm going to a&p school this spring. I've been studin transportation issues for many decades?? from my experience in the circus ... transportation is the biggest issue for performers.
Holy crap...i've seen passengers more scared of turbulence than the people sounded on here. I know that a plane can continue flying on one engine, but i'm amazed at how level the pilot was able to keep it. I'd always thought the wing with the failed engine would want to droop
I a few years we become shot´s from the flight deck, inside the cabin, tower view, fire fighter helmet cam etc. Impressive video!
I like how they are still windmilling a bit even though they are feathered.
Great landing..... When I've flown on the dash in the UK it's more like a controlled crash landing lol
I fly many times a year on the dash 8 Q400 in England and absolutely love it !!!
I live in the country that the q400 is made and what's weird is I've never been in one. Also, they're my favourite plane.
***** Yeah I KNOW!
Birmingham?
I know right. my least favorite plane is the 8
@TheA340guy when a cellphone searches for a signal it interupts the pilots radio with that annoying beeping that you have probably heard on your car radio right b4 your phone rings, In aviation communication is key , you dont want your phone interupting the pilots communication to the tower then mistakes due to poor communication might happen . but other than that your phone will not bring down the plane .
damn that engine surge sounds horrifying as hell, if i was on that flight id seriously start thinking about bringin parachutes on board just in case
Very Professional in every way, the whole crew did a fine job...
@EnnCamp some do. its all dependant the number of hours and what the company pays. but you have to trudge through mud to get to green pastures sometimes.
3000 hours of flying Dash 8s. Never had an engine failure.
Looking at the video footage It is certainly a problem either with the turbine itself surging of the governor controller on the prop. The rpm certainly is fluctuating. If prop governor fails it called result in a prop runaway which is not good and worthy of a engine reduced power or shutdown
Left engine is the critical engine with prop spinning anticlockwise when viewed from the front due to corkscrew effect from the prop wash onto the vertical fin which provides a kind of stabilising effect should the right engine fail but again it was the left that pooped and the dash 8 does have a nice large tail and all conditions were favourable
The Dash 8's rudder is a two piece surface, and VMC is below stall speed, so I'm told.
Dash 8 doesn't really have a critical engine like the smaller multi engine piston planes a lot of pilots initially learn on. I flew the Dash 8's for 11 years. The Dash 8 is a well built airplane almost to the point of over engineered...
This is awesome!!!! I didn't think these little guys could do this!!! I'm so psyched now about my flight.
no joke, all the training they went through to handle a situation like this and no applause?? i would have clapped and cheered
@killbilly069 no that's a sign of how safe flying is that an engine failure is not a deal breaker.
First of all I've been on several dozen flights for business. Some flight crews say its not a problem to take pictures and some say no. Either way the only electronics the could screw up a flight is the ones that send and/or receive radio signals which would hamper navigation instruments. Notice even though the plane hasn't stopped the flight crew says the use of cell phones are now permitted. Navigational instruments are not needed then.
Notice the Beta lock or Throttle Quadrant Control malfunction coincided with the retraction of the landing gear.
@188043 Nah, the aircraft has no reason to wobble. Without the left engine, that side of the wing has no thrust so effectively the right wing would travel fast than the left which would cause the right wing to lift, so right alieron will reduce the lift of the right wing because that flap moves up, therefore they balance out. Plane still flies normally. I've pracitced engine outs in a single engine plane and its not much different except you have toput the nose down to maintain airspeed.
No NTS on a Dash 8. They use an autofeather system, but only for takeoff. We disarm it at 1500 ft.
These guys deserve a thumbs up.
This happened over Macho Grande and Elaine did a great job with the passengers.
My stepdad once had a low oil pressure warning for the #2 engine on the dash 8 Q400. Immediately shut the engine down and diverted to Durango.
there are fuelselectors in the cockpit, so the pilot can choose which engine should use the fuel of which tank.
Airliners are required to have controllable multi engine aircraft under US regulations. And yes, Henery, depending on the placement of the engines and other factors, the engine out scenario is a handful for the pilot. In the big jets it is generally not as much of an issue, but the smaller the aircraft the issue is controllability in the event of a failure - and that issue becomes more and more difficult as weight and winds, load balance, temperature, and the airplane's performance in general is effected. While two engines provide excellent power and greater takeoff and cruise thrust, the loss of an engine in a light twin is a loss of not 50% of the power, but equates to 80% power loss. Not as significant with an approved transport like the venerable Dash 8 line, but in a Beech Baron, Piper Seneca, Cessna 310, etc., the pilot must react very quickly and correctly to control the aircraft from rolling over, and maintaining directional control and airspeed control. It can be visualized by imagining yourself paddling a canoe upstream with access to only one side of the canoe - you can only turn in one direction easily, and if you paddle too hard you will be swept around downstream. Returning upstream from that point is so difficult in many cases depending on various factors that it might be impossible. So it is with the light twin.
Good to hear you practice without passengers! Reminds me of that recent incident where the crew played the wrong French language warning about ditching into the sea rather than possible turbulence.
@MrCaptainSr79 Oh yes, sorry you couldn't know that I live in Finland and here warm, dry summer lasts only for about three months else all it is just rain or -30°c and snow. Because SAS (Scandinavian Airline Systems) had these planes about four years ago, all of 'em had landing gear failures and it was catastrophe here, they really were dangerous because the nordic weather rusted those planes fully.
You can hear the power surge and see the fluctuation of the propeller speed on this video. Great landing too.
It's an unusual situation but not dangerous unless there was fuel contamination which might cause both engines to fail. The Dash 8 has enough power in one engine for flight in any situation, even take-off. And I've always hated passengers who clap when a plane lands. You know they're the ones who hardly ever fly.
US Airways Express. I do not remember the registration number. I guarantee you could find out on the NTSB website.
Thanks for watching.
No fatalities, and the crippled plane landed safely...That's the best part...
@txeriff2k6
Actually No, We can "Feather the prop", Ie. Stop it spinning.
A Spinning prop, known as Windmilling, actually causes huge amounts of drag and makes it rather difficult to fly the plane straight and level as the plane will want to yaw/Turn towards the side with the shutdown engine. So in this case the Prop has actually stopped although you are correct, often when filming/recoding footage this effect does happen.
And don't call me Shirley !! "We need to get these people to a hospital" "Why what is it" "Its a building with sick people in it but that's not important right now. "Trust me to pick this week to quit sniffing glue". I love Airplane.
twin engine turboprop....lands balanced on 1 engine???? fuck yea!!!!!!
@24262748 actually its not designed to stay in air with one engine its designed to fly with two engines. but if one fails then the other is a fail safe/ to get them to ground. the pilot has a procedure he runs through if such an occurance should happen.If the plane were designed to run on one engine it would be central like a cessner 172 for example not on a wing.
@188043 wouldnt be too hard for them, just adjust the rudder and or aileron trim to the right and its effortless
@yisasakopaka buddy.. as a pilot my self.. this is something super normal.. he was trained to do stuff MUCH worse than this.. full throttle on the other engine and full rudder thats it the flight is maintained staight and level.. those guys would never get into that flight deck if they warent experianced to deal with such thing as this.. but well done, even though it wasnt critical. I see this couple times a month
yep but that is in general just proper use of controls, procidures and energy managment. but yea its diffinatly on the take off its the most dangerous. its a lot of look after the aircraft and it will look after you.
@JGunlike" ..its an accident only if there was substantial damage to the aircraft and/or passenger during flight .. like crew members incapacitation in flight, in flight fires, a/craft collision..etc are examples ..an engine failure with no ramifications isn't a major incident to FAA. The FARs define "Incident" and "Accident" separately.
Anybody whose played Microsoft Flight Simulator knows how ridiculously hard it is to fly one of these planes with only one engine. I crashed at least 50 times before finally landing one.
Reasons all electronic devices are banned:
Some cause radio interference
In case of an emergency, you could loose grip and the device could hit someone else.
It's a distraction. You aren't going to know what you need to do in an emergency if you aren't paying attention.
Good Job to the pilots of this Dash *. Nice to know that it can fly with one engine...We have them flying in Hawaii. Island Air ..I love them..Nice posting...thanks!!!!
Wow cant belive how calm they are.
They shut them down once in a while so they don't both wear out at the same time. Kinda like rotating your tires with the spare.
@yisasakopaka
The captain was doing his job, landing with one engine isn't all that difficult believe it or not. It's something you must learn to do in order to get your multi engine rating, and then in each aircraft that requires a type rating. Pilot just doing his job.
Not ALL aircrafts are designed to fly on one engine. Per the FAR's Part 23, aircrafts under 6,000lbs an aircraft is NOT required to maintain a positive rate of climb on a single engine, with the critical engine inoperative...
@e081194eng yeah they use them as shuttle planes but now they are being replaced for mini jet planes its sad
I just want to tell you both good luck. We're all counting on you.
Great job CREW. Another expert performance by a well trained crew.
I believe that the cold weather had some particular effect on the landing gear mechanism. In Australia there are lots of Dash-8s but no issues have been found.
@naisi not true at all. it can and does interfere with the communications and instruments. handheld games, cellphones, pretty much anything emitting radio frequencies. i hear my own cellphone seeking service through the headset quite often - i'm just not required to turn it off.
I think that Beta lock out system is the same as Beta backup Protection System which is located in PCU-(pitch control unit) its use is for agains reverse pitch in flight..
Jesh, one engine down and its still landed like a feather, I just love this plane.
You actually hear the surge as it's shutting down. Nice cool max right bank before doing the tar-drop maneuver RTA
Problem is that it runs. All the crew had to do is bring the props back to 900rpm and the problem is done.
This was a new captain and I am sure that he jump the gun by shutting it down. But he did a great job and nice job by that crew.
And nobody applauded the captain when the plane landed. For shame...
+hawksbowlbound
just doing their prayers
Cause everybody s heads was busy...they cleaned their asses from the sit in their pants
agree!
Everyone was on their phones trying to get the first upload to utube
Technically this wasn’t an emergency situation quite yet. The engine was still working, but as a precaution they shut it down.
That was one smooth landing. Excellent skill.
@naisi this function of showing people the way out is secondary to their primary function. as far as security a 130lbs woman with no weapon is not security. checking the seatbelt is a safety issue not security issue. the first attendants , stewardesses were overpayed drink slingers.. put there for the convenience of the passenger. you can safely operate a plane without them. I can find my own way to an emergency exit without an overpayed cocktail waitress. I've followed aviation most of mylife
@CA477544 No. That is an urban legend. It is absolutely safe to use phones in flight.
The airlines just don't want you to for the other passengers convinience.
Amazing video - Real edge of the seat stuff!!
Thanks for sharing... the sighs at the end say it all!!
These were a replacement for the F27 Fokker Friendship. These were a brilliant safe plane to fly and virtually indestructable. Search the net for these Dorniers or Dash 8. These Dash 8s are NOT that safe or so sooooo reliable, check the net.
The pilot sounds calm and professional, but the flight attendant sounds quite scared. Obviously the pilot knows that it's perfectly possible to land safely with one engine, but the FA doesn't.
Every year we fly on the dash 8 or the atr 42-600 n the Bahamas and thank god non of the engines never fail in fact my family and I might be flighing on on tomorrow and I really hope the engine dont fail
You got that backwards on the critical engine part. A failure of the critical engine causes the worse flight control difficulty.
Beta Lockout (mandated by FAA AD) is such a pain to deal with. That system has caused damage to many prop assemblies after failure of this "protective" system... The system becomes active after weight-off-wheels and RadAlt above 50 feet AGL. It takes lightning fast reflexes from the crew to prevent an over-torque of the feathering prop at full take-off power...
It is simply amazing that in today’s world not only does “everything” seem to happen with video recorded but there are two angles available. Not for nothing but the flight Captain’s request was violated with the very recording of this and you could be charged with a Federal crime. Were I to be in danger of dieing (again) in an air crash though I’d probably try and record it too and say to hell with the regulations!
he (or she FO?) even touched down right on the 1000 foot marker, i.e. exactly where it's supposed to go. applause to the crew!
Did anyone hear the engine noise, it sounds like someone was revving it. when that happens you know youre plane is likely having some serious engine issues. And it seems as if the dash 8 series 400 has been having trouble with everything from little computer glitches to landing gear and engine failure
@KingMawerik So I say again, why are they lucky that they were past V1? I'd take a
the magnetic field they put out can fuck with the compass, not that the pilots use it unless they have a vacuum failure (in a conventional cockpit) or some type of crazy electrical failure in glass.
@YYZZZYYY Thank you! As a pilot I can't believe the years of training, thousands of dollars, and everything else we have to go through just to make enough to qualify for food stamps. Definitely need a pay raise!
The captain and first officer who saved your life on this flight are probably earning a COMBINED total of $60,000 a year! But we go where there is work because it is better to be underpaid than unemployed! Also, any airplane used commercially is required to CLIMB well with one engine failed otherwise it wont be certified and put into service.
