- I am committed to bringing you exclusive footage from significant incidents and accidents, and today is no exception. This video presents exclusive, never-before-seen footage and imagery associated with an April 20, 2022 accident in which a United States Air Force Rockwell B1-B Lancer supersonic bomber experienced a catastrophic engine failure, explosion, and fire during a ground run-up at Dyess Air Force Base, Taylor County, Texas. One person received minor injuries.
The Accident Investigation Board report summary follows:
On 20 April 2022, at approximately 2216 local time (L), the Mishap Aircraft (MA), a USAF B-1B, tail number 85-0089, assigned to Dyess Air Force Base, 7th Bomb Wing, 7th Maintenance Group, 7th Aircraft Maintenance Squadron, experienced a catastrophic engine failure and fire on a the #1 engine while undergoing maintenance on the main ramp at Dyess AFB, Texas. The MA suffered catastrophic damage to the #1 engine, as well as extensive fire damage to the left nacelle and wing. Debris from the explosion struck one Airman who suffered minor injuries and was treated promptly at the local hospital. The estimated cost of damage sustained by the MA is $14,943,680.00.
Shortly before the accident, the Mishap Maintenance Crew (MMC), comprised of members from the 7th Aircraft Maintenance Squadron and the 489th Aircraft Maintenance Squadron, performed routine corrective maintenance, in accordance with technical orders, in response to the MA's malfunctioning #1 engine variable area exhaust nozzle. During run-up to maximum augmenter to verify correct performance of the #1 engine variable area exhaust nozzle, the #1 engine catastrophically failed, ejecting its 2nd Stage Fan Disk from the intake section and severing fuel lines, which caused a fire to erupt in the engine. The 2nd Stage Fan Disk continued to fly away from the aircraft and landed over five hundred feet from the MA. The MMC executed emergency engine shutdown procedures and egressed away from the aircraft. Emergency crews quickly responded and extinguished the fire within ten minutes.
The Accident Investigation Board President found by a preponderance of the evidence that high cycle fatigue on the #1 engine's 2nd Stage Fan Disk was the cause of the accident. Laboratory testing demonstrated that high cycle fatigue initiated a crack on the surface of the 2nd Stage Fan Disk at the corner of a blade slot and the forward face of the disk. The crack, once initiated by the stress induced from repeated acceleration and deceleration of the engine, was propagated by a mix of high cycle and low cycle fatigue. The crack and its initial growth increased the stress beyond the 2nd Stage Fan Disk's yield strength, leaving it susceptible to low cycle fatigue. The surface crack grew to a depth of approximately 0.7 inches before the 2nd Stage Fan Disk broke apart causing the #1 engine to fail catastrophically. The root cause of the high cycle fatigue that caused the initial crack in the 2nd Stage Fan Disk could not be determined. No factors substantially contributed to this mishap.

Better on the deck than at 50 thousand feet!
B1B, not Concorde!
sure about that ? conflag risk to all those parked around
Probably it would have been better at the altitude. I guess the low pressure combined with high speed would just blow the fuel away before it ignited, and even if it ignited, the damage would be much less severe. The plane would have landed just fine without single engine.
Uncontained engine failures have an unfortunate tendency to also sever hydraulic lines, however. And with several hundred knots of airflow to change the behavior of the fan disk once it decided to launch into the wild blue yonder, losing the entire aircraft and possibly the crew instead of "just" a fourteen million dollar repair bill isn't out of the question either.
No, much better on the ramp than at altitude. Or, given the nature of the failure, during takeoff when the engines are pushed hardest.
I agree,we would most probably lost the airframe.
As former Dyess firefighter ( 27 years) I can tell you that was a fine response. With the new fire station located so close to the ramp, the standby requirements were changed to require standbys only on green engines and as requested by maintainers or other special requirements.
I guess you saw how long it took fire to get there. Thats why you left that comment.
Just glad no one was killed, the jet engines failures are no joke, they oftentimes can be quite spectacular and dangerous.
Damn, thats expensive !!! Thx for sharing with us mate 👍
I love these real-world incidents...keep them coming! I can't believe you guys don't have a bigger subscribe count. Been with you guys since you were small numbers 👍
Really interesting footage, another great acquisition, thank you! Did the AIB report say anything about maintenance? The root cause of the crack might not be knowable but would a different maintenance and inspection cycle have caught the crack?
The engines get overhauled at the OC-ALC (Oklahoma City Air Logistics Complex). Not sure when the last last time the motor was there, but I'm sure they investigated that. I'm pretty sure they do NDI inspections of the disks, etc., and wonder if they missed this.
I don't remember any mountains like those at Dyess AFB.
They are escarpments. Not mountains. But I found it amusing because when growing up in Abilene I called them ‘mountains’ too!
Interesting how you can see the cool foam/water being sprayed as deep black in the thermal image.
Also, in the last sentence of the second paragraph in the report should read "fire" instead of "tire".
Fixed. Thank you.
Boy, I'm here to tell ya, this has to be the coolest piece of infrared footage I've seen in a long time. Life is a series of experiences, former fire captain. Seeing that discharge from the Oshkosh? Just wicked cool. Spent some time with ARFF rigs years ago, that was a sight to behold.
I was stationed in Paktika Province at a Fob Boris around 2011. I was part of a team that monitored enemy actions around the Fob and out to around 20km with IR and high def camera systems. I remember being on watch looking to the west at around 0300 and seeing a B1 flying just above the mountain peaks at a high speed; i couldn't believe my eyes that I saw such a big bird flying so fast and low; i was amazed.
Awesome channel, but seems to have gone dead. Wish it would return, it's very educational!
Well, that seems to be a little too much nitro.
Keep up the work! We all appreciate the effort
The fact that only one person was injured is amazing.
Thank God they were on the ground when this happened, if they had been airborne , it could have been tragic
Appears someone was injured. Hope they are ok.
And now it's a parts bird.
I was sleeping in my dads truck when we were 78 ft away. I woke up to a loud bang and flash. Seeing the fire made me freeze..
Amazed and Thankful that there weren't more & serious injuries or fatalities. Federal Civil Service Crash crew member in mid to late '70s for the Navy. Can't believe they are allowed to do high power engine tests/maintenance on the regular flight line/ramp. Any time a jet was undergoing high power testing, it was moved to a remote, high power test area and a fully manned crash truck was sent to standby with crew in full gear. Spent many hours on such standbys.
Excuse me for my apparent ignorance, but shouldn't aircraft be better dispersed or in revetments to protect against this and possible attacks?
ATTACKS in Abiline Texas are Purdy rare
boy, the fire crew sure knocked that blaze down fast! bravo guys!
I am left to wonder what internal fire suppression systems jet aircraft carry, and why/how did it fail in this case?
If the Nacelle is blown off, fire suppression is not affective. I bet they followed the bolt print anyway and fired the bottles. In my 20 years on the line I saw three engine failures in real time. Its very scary. Salutes to the B1 run crew.
@@williammooney8499 got your point, I was unsure if the nacelle was removed after, for pictures but clearly not. I assumed most of the ejecta would have blown rearward, but I see when the blades are blown off on such a powerful engine, it's not much help.
Mercifully, it wasn't armed with regular munitions. Or the level of destruction would be awful.
Looks expensive.
Yikes! 😯
Wow at least it happened on the ground.
The dod reg is if there are aircraft engines turning up, there is to be a rapid response unit [ie Hotspot] posted & has to be on scene and deploying agent within 60 seconds of the incident starting.
That makes sense; in the two minutes before fire suppression began, loads of damage took place, and it could have been much worse.
@@timothypaul984 I was [med retired] a USMC Crash Fire Rescueman at MCAS Yuma, Az. and whenever there were aircraft engines turning up [both civilian & military] there was a "hotspot" posted as the first in response truck
This response appeared to be slow in the vid
Really? What's the reg? Can you cite a source? "Turning up" is not a technical term. Not sure what you mean.
@@RyeOnHam Gee I don't know, jet engines turn, so there's that. Does everything have to be technical or you're clueless? Are all your conversations filled with cite your source, what's the law, what's the legal definition? Well are they, huh, huh, answer, cite your source?
@@bruce2357 Nobody asked you, Bruce. He's quoting a regulation. I'm not aware of the regulation. For fairness sake, are all your conversations filled with trolls? Seriously, he was blaming the mechanics and fire personnel for the accident by implying that they weren't following 'dod regs'. I'm calling bullshit. You can't call bullshit on me calling bullshit, Bruce.
Whoa
oh...mann...
That will buff out 😂😂
Good!
Great another dead channel with no explanation. So much for being a loyal and longtime subscriber
lucky that it happened on the ground
So that's where that pesky 10mm socket got to, been looking for that.
😂😂😂
Does this channel crashed like an aircraft? I am still subscribed but this channel has no new content anymore.. 😢
They had four ARFF trucks respond?
I was stationed at Grand Forks in 1979 and a B52 engine caught fire when they started the engine up, back then they were loaded with nukes, but in both cases, glad it happened on the ground and not in flight
Great work as always, WYHS!
Well...that's one way to warm up your engines
Yep.....Another reason the well prepared man never leaves home without his Zippo!
Superb video by the way Guys, well done.
It's a shame it'll never fly again. They picked a Bone from the Boneyard named Lancelot to replace it.
Looks like an un contained disassembly of the turbine ! At least it wasn't airborne !
Was the Aircraft repaired or withdrawn from service due to the damage.
+@mt5144 It sounds repairs are too expensive. A replacement B1 was withdrawn from the boneyard and made flyable, and sent to Oklahoma for extensive upgrades to return to service.
Glad no one was seriously hurt. $14 million 😮
Do you think they got the hell outa there. Or what?
Was the aircraft a write off?
This also will be a learning experance
Mr. Play-It-Safe was afraid to fly
He packed his suitcase and kissed his kids good-bye
He waited his whole damn life to take that flight
And as the plane crashed down he thought "Well isn't this nice"
And isn't it ironic, don't you think?
Dyno fail- 10k, B-1 engine fail- 14 million. Yeah, the gov't has all the fun.
I dont remember this being on the local news. Must have been suppressed for whatever reason. Weve got all the big 3 here plus FOX.
Sweet
KA BOOM 💥...
who thinking at first, its from 60s?
$14,943,680.00. ...... I would have expected a much larger number...... From what I have read here and there, this is an obsolete airframe that is being replaced.
I am also amazed that an explosion of this magnitude didn't kill anyone.......
we dont build new b1's they do however update them from time to time
Obsolete? Not hardly. That airframe has $14 M just in hardware, hehe. Being replaced? Look into the upgrades being rolled out for its sister, the B-52. Those engines alone cost more than that.
Wasn't the first one that it happened to.
As a hater of the military, I approve this mess.
There went 300 million dollars...
Ground wire was still intact tho.
Camera man gets C-
From the wording in the description, is it correct that this aircraft was NOT a total loss and returned to flying status?
Where did you read that? No way it would be returned to flying status in a year.
@@kali6651 I didn't read it anywhere, I was asking if it was returned to flying status. The description states a cost, I was asking if that was a repair cost.
@@TJH1 All it says was that was the estimated repair cost. I don't understand how you could be confused and ask if it was returned to flying status.
Trevor asks a logical question and is immediately called a retard in the most passive aggressive manner possible welcome to the internet 😂
@@kali6651 Seething little freak
Pilots survived????
A giant 5 foot in diameter titanium Ninja star flew 500 feet through the air and didn't hit anyone... I'd say that was a good day, not a bad day.
Another Jet sent to Tucson Arizona
I live right by the Boneyard lol
What you haven't heard... the reason why it blew.
Read the description in the drop down box below the video.
"The Accident Investigation Board President found by a preponderance of the evidence that high cycle fatigue on the #1 engine's 2nd Stage Fan Disk was the cause of the accident.

@@JonBowe Good thing that wasn't in the video or else it may have made sense. Can't have that!
New engine 25 mil not including labor😬
As a matter of interest why haven't B-1's and B-52's been replaced by B-2 stealth bombers by now?
The B2s were too few. At the time they were made, the were more costly than their weight in actual gold. Only 21 were made. Now the B1 and B2 will both be replaced by at least 100 B-21s in the next few years. The B52 will still be around with the B-21s.
The B52's and B1's are at Dyess. The B52's are constantly being upgraded and will be good for many more years. Barksdale has B52's and B2's. The B2s were grounded but should be back in service soon. The B52s were all built before the air crews were even born. They are still the best long-range bombers we have.
Because b-2's are already out of production because of their costs
Only 20 B-2s were ever built...That's 1/3rd the number of B-1s currently in service, and almost 1/4th the number of B-52s currently in service.
They're too expensive, only built for a very specific type of mission (and thus don't the versatility of B-1s and B-52s), and are becoming outdated (they'll soon be replaced by the B-21).
because you can only fleece the taxpayers so much
I know this feeling, I had a car that threw a rod once...
You could see the fuel spread, gnarly. I will assume that the aircraft is done. Did they pull one out of mothballs or, one less in the arsenal? They should pull TEN to put back in service.
So... A Bone got smoked on 420...
Time to scrap that bird.
Not good🤔
Tax dollars at work
It did happen on 420 so…
I can hardly believe that the loss was less than $15M! Considering these aircraft are priceless, the fact that they were able to limit the damage is a testament to the airplane, the maintainers and the emergency responders. Kudos folks.
I do find it ironic that this Bone was lit up on 4/20!
Instruments of war aren't "priceless"
@@BrownEyePinch ok, how much to replace a B1?
And that it was part of the "7th Bomb Wing, 7th Maintenance Group, 7th Aircraft Maintenance Squadron." Not so lucky after all.
You must have stock in the military machine.
@@popsfereal no, I was just a guy on the ground who was able to be just a little braver than felt knowing that there were dudes in Blue ready to rain hell if I asked.
Seemed like an incredibly slow response from fire/rescue!
I thought the same. What I know about it could be written on the back of a postage stamp mind...
I'm guessing that having more crash tenders, and where you'd site them, presents it's own problems..
I have responded on that very flight line hundreds of times and that was an excellent time. 2 min 12 sec to get up make it to your bunker gear, get dressed and drive to the end of the Bone ramp. BTW the station is over 100 yards long, you gotta hustle to make the time requirements
Did the pilot survive ???
From the description: "One person received minor injuries." Probably ground crew.
I came to the comments section looking for this and how it started.
All the so called quarterbacks here bitching about response time? Do you think they should have a fire truck waiting while they startup? No doubt the investigation team will find the reason for the malfunction or root cause of this failure. I doubt seriously the USAF is going to scrap that aircraft for one engine failure. The wiring harnesses will be replaced as well as any damaged components and any airframe damage will be repaired as well as any flight surfaces that might have been damaged. That foam stopped the fire quickly and the engine was in the repair bay to discover the point of failure. The IG will take 4:40 it from their and maintenance crews will be given updates as it happens. When the first cause is determined a situation report will be issued to those with
clearance and obviously you are not on that list. It did not look like the airframe
Was damaged that bad and I would expect this bird to be put back in action after all repairs are complete and the test pilot sings off to make it available. I have seen much worse damage and the aircraft was back in action in much less time than you might think. These are not toys but weapons platforms.
It would very expensive to repair and probably a lot more economical to use it as a part bird. Once you actually start pulling it apart to repair you usually find more and parts need replacing and from where do you get these parts plus time and labour are generally always under estimated. I would say 2-3 years to rebuild would be not be out of the question.
What I haven’t seen…is this channel produce content for months. And timed when Jeremy DeWitte went prison. Coincidence, maybe. Hella good rumor? Absolutely.
Did ground crew not have any fire bottles near by to try and suppress the fire before the fire department showed up?
Apparently not.
Until you have been within pissing distance of a JP-4 fire, you have no idea what hot is.
Maybe a small fire, but that one was serious from the moment it let go, and no one would have been effective with a 150lb Halon type bottle, at best, you can get 40 feet to the base of the fire.
That fire was already beyond the effective4 ability of that bottle, and at best, you might have two of those bottles in the vicinity of that event.
At that point, getting tow equipment and moving the adjacent aircraft might have been the only effective thing.
When the shit hits the fan, it moves faster than you can realize.
Easy to sit and watch a video and think of all the things you would do.
Until you have been in such a thing, you have no idea.
(and for those of us that have, we can see that for what it is)
And, yeah. It tends to piss us off.
@@trunkmonkey9417 well I have experienced fire with an aircraft since I’m in a squadron. And the first thing we did is grabbed all our fire bottles around the aircraft and wheeled them over to try and suppress it before the fire department got to our bird.
@@ryanfitz2214 Context.
I have dealt with JFS fire on F-15 in a TabV in Bitburg, Start Cart fire on F-4 at Eglin and a AB fire in tailpipe on shutdown an F-15 in the hush house. Couple of wheel Brake fires when in AR shop, and most of those were small in comparison to the B-1 engine fuel fed at a high rate and rapid conflagration.
Less than a minute of use for a 150lb bottle, and that is if you can get close enough. 45 feet is all the reach of the stream, and as large as that fire is, having been near that close on a small fire, and having hair singed off, and "sun burn" redness to exposed skin (face and hands), I'll bet no one would have been able to get within 100 feet of that, and most unlikely close enough to get the stream to the base/source of the fire.
I wouldn't give anyone of those maintenance folks any crap about putting distance from themselves, and focusing on moving other aircraft.
We can replace assets.
There are always fire bottles stationed at the aircraft but with this fire it was better for the maintenance folks to evacuate to a safe area and wait the emergency vehicle is. The fire bottles would have done little to keep this fire d
At least no one was hurt , only a few hundred million dollars tax payer $$$ 👍
Not a very good response time from the fire trucks. Maybe they should go two-tiered, first guys just jump in the truck and go in their jammies to expedite, and the second team spends the extra time and gets suited up.
Lemme guess, ahhh Putin done did it! Eh Cleetus?
Damn that Putin. He's done it again.
It sure took the fire department long enough to respond. They were probably doing their diversified training.
This happened on 21 April, 2022. Not a very timely post.
US tax dollars HARD at work and the rich get richer with tax breaks
Just another waste of tax dollars... :(
Had that been the Navy, ground personnel would have been running toward the fire with portable fire suppressors, to attempt to put out the fire before the arrival of the ARFF and to attempt to keep it from spreading to neighboring aircraft. All I saw in this video was the arseholes and elbows of fleeing USAF personnel!
and the brass would be randomly picking a new seaman out to take all the blame. and not accept that this airframe has modified engines that im sure their future employers came up with. this being the secon aircraft to have the same problems ground 50 of them
@@matthewgibbs6886 Are you being serious? You are obviously are creating that conspiracy theory scenario in your head. You have no idea how Naval Aviation works, that much is clear. First off, personnel in the Air Wing under the rank of E-4 are called "airmen," not seamen. Secondly, the Navy trains every enlisted sailor to be a firefighter. I went to a week-long firefighting school at least twice during my time in service, and I had regular scheduled refresher training to remain qualified to work on aircraft on the flight line and on the flight deck of an aircraft carrier.
Plus, you obviously do not know how aircraft maintenance works in any capacity. Squadrons in every branch of the military are not allowed to modify aircraft in any way without permission from the DoD, and the modification is a minor one designed and recommended by the manufacturer and it does not make major changes to aircraft performance or safety. If there are any serious modifications to be done, especially to gas turbine engines, these are done at the manufacturers level, with the permission and acceptance of the Department of Defense.
The U.S. Navy has a standard guideline for how all aircraft squadrons are operated and how acts of maintenance are to be conducted. It is NAVAIR 4790.2D, the Bible and final word for all naval aviation organizations. In it, it specifically states that all maintenance turns done on the flight line must be attended by personnel with fire suppression devices. It seems the USAF is somewhat lacking in this aspect.
Anyone who willfully or carelessly violates official Naval aircraft maintenance doctrine, and it results in the destruction of an aircraft, will rightfully face a Courts Martial, resulting in a lengthy stay in Leavenworth.
So, no.The "brass" does not single out a random "seaman" to pin the blame. That scenario is fantastic, and should be considered merely a paranoid fever dream.
You can tell they don't teach fire fighting in the air force.
At least the Air Force still has it's Diversity and Inclusion .
I hope the USAF junked the plane after the fire, it's more than 40 years old and not worth repairing.
if you're gonna film something, at least know how to hold you phone. very dizzying footage......not even worth watching. (like a bad JJ Abrams movie)
