I knew Bruce Bell and flew with him at Golden Gate Airlines. He was a standup guy with a wife and four kids.
Can lessons be learned in this case Sir ?
Remembering him as a standup guy who had a family makes the loss even more heartrending. Thank you for sharing your memories of him.
Very sad story.
Life not fair for some. Every day I’m thankful for that day. What a said story. Prayers for the families.
It's a shame.
As I recall, this plane’s initial attempt to land at Russian Mission had to be aborted at about 300’ agl due to a four wheeler operating on the runway. The crash occurred on the go around for a second attempt to land. May be worth checking out.
I also concur that it is pronounced EEE-MON-ICK.
I had heard that too but never heard anything to substantiate it.
What was a vehicle doing on runway was noone aware thst a flight was coming in
I knew these guys and was at NAC when this happened. It haunts me to this day. I couldn't tell in the video, as I didn't watch all of it, if it mentions that the F/E (rex) and Gary the F/O had switched seats. They missed the first item on an engine shut down. If I remember right they were extremely fatigued with several long days before this trip. Anyways ,all good men, flew with them often. Not forgotten.
Up until this crash NAC had never had a fatal accident since it's start in the 50's.
The narration in this video is a big improvement over the previous ones I've seen from this channel. It flows a lot more naturally.
Thank you for noticing the improvement in the narration. Your feedback is encouraging as I continue to work on enhancing the quality of my videos. Thanks for watching and for your support!
@@flightpathaviation1 There's a tiny bit of chirp in the high frequency region, which is probably just resonance in the microphone. If you're using a headset with in-line mic, consider holding the mic between your fingers to keep the plastic from vibrating. You should be able to EQ it out without issue if it's a regular mic. Your other audio sounds fine, so it's definitely a mic issue. Diction, speed, and tone are great though. 👍
Very sad, DC-6 operators still talk about this accident frequently. A very rare completely catastrophic failure of the P&W R-2800
Well is is no secret in the industry that fire in a radial engine is very serious and if not immediately extinguished the wing will burn! Great video.
The scary thing is it was only 5 minutes from first fire to wing coming off, and the crew did shut the fuel off promptly even if their mistake caused problems feathering. Unlike pod mounted jets, the fire plume from these piston engines is going to impinge upon the wing spar. Given that every conrod on the first row of cylinders had punched through the block, oil must have been pouring out, would feathering have made a difference ?
Only 6 of the 704 DC-6s produced are still flying. The last one rolled off the assembly line in 1958.
It was a local kid riding his four wheeler. In my years of flying in the area it was common to have four wheelers or snow machines using the runway as a racetrack. I went on a night medevac to arrive and find most of the runway lights shot out. Very demanding conditions.
Outstanding video and audio. No idea how you generate this stuff, but it's very well done.
As far as understanding the mishap, however, it's missing a few key points (or perhaps I just didn't see them). Was the engine fire procedure an immediate action (done from memory), or a written checklist? In other words, did they fail to retrieve a written checklist, or misremember a procedure? The video implies the latter, and mentions human factors, but doesn't really explain what they were.
Hopefully that's helpful. Not at all bad as is, but it seems to me it could be much better with just a little more detail.
tombauer5293 is correct that they aborted because of kids playing on the runway otherwise they may have made it OK. The engine fail/fire checklist that was done sounded incorrect as I remember it. I believe it should have been 1. Feather #3 -check for feather -check for fire (I believe the feather button shuts off fuel and oil from the oil tank.) If fire still exists then 2. pull the fire handle to discharge the bottles. Different carriers may have different procedures though. The P&W R-2800 is viewed as an almost bulletproof engine with excellent reliability. Sad story for a great airplane and a fine company.
Over fatigued engine NO.3 that self destructed started the whole catastrophic disaster off. Easier to blame pilots though. Same old story.
The start of the fire was not the fault of the pilots, that they didn't feather the engine before they hit fire suppression is pretty clear cut. Would that have saved the plane, who knows?
I had quite a few friends at NAC. The word i got was that they went around so as not to take out the school close to the end of the initially planned runway.
Your videos are well made with the exception of then endings. If you could nail that issue down your channel would grow much faster and gain more engagement. The endings in your videos are just too abrupt. All the best and take care.
Thank you for your constructive feedback. I'm always looking for ways to improve, and your point about the abrupt endings is well taken. I'll focus on refining this aspect of my videos to enhance the overall viewing experience. I appreciate your support and wish you all the best too. Take care!
Hmm, it didn’t seem to matter too much to me - all channels on aviation disasters using the exact same format would be less interesting. I wouldn’t really know without seeing it done both ways, but you’re never going to please everyone.
I was just excited to find another good channel on aviation. With fewer commercial accidents and mishaps, the same well known ones seem to be doing the rounds over and over. Sadly accidents from General Aviation I keep being told, are actually increasing and finding a niche there as you seem to have done, may in itself draw subscribers. There are several channels analysing new GA accidents, but older ones with fewer victims aren’t much covered. That’s a bit sad, that it needs to have hundreds of deaths to sensationalise an accident 🤔.
@@moiraatkinson Trouble is, the GA fatal rate has at times been an average of 1 per day, so it's tough to keep up, although the numbers are starting to trend down. We need to learn all the lessons we can from other crashes in order to avoid repeating them and to find and address problems with aircraft, components, pilots, controllers, and ops.
@@moiraatkinsona lot of older commercial crashes still not covered
Your emphasis on learning from these events to avoid repetition is a critical perspective in aviation safety. Thank you for highlighting this significant aspect.
New subscriber…Enjoyed the vid & look fwd to future content. 😉👍✌️
Welcome and thank you for subscribing! I'm glad you enjoyed the video and I'm excited to have you on board for future content. Stay tuned for more..
@@flightpathaviation1 will do. 😉✌️✈️
Why wasnt the jump seat pilot also given a commendarion?
Linjeflyg Flight 618 had a similar procedural error in the airline but this time with the de-iceing system.
The plane stalled when the full flaps where deployed because of ice on the wings causing an airflow separation.
Had they used 10 degrees less flaps they would have survived
The crash is best known in Sweden for crashing in a residential area without fatalities on the ground.
The ol' "X" Factor...human induced negative contributions vis actions or inactions. Sometimes the "X" factor is positive when cockpit resource management are applied correctly.
They may have been highly experienced pilots but how many engine fires had they dealt with previously? Is this something that is dealt with in training and possibly not reviewed? It’s one thing to do an exercise in your head and usually quite another when confronted with it in reality.
Subscribed! 👍🏻
We dealt with it often. I had 18 shutdowns on DC-6s
Longhair pilots with 20 thousand hours are closer to 4000 hours compared to shorthaul bushpilots. It's all about sectors and takeoff and landings.. hours don't reflect flying experience.
A couple of questions-
Firstly, why exactly do props need to be feathered before activating the extinguisher?
Secondly- what exactly was burning? If it was fuel, couldn't they dump it?
Pulling the fire handle on the DC-6 shuts off the fuel and oil connections at the firewall, meaning the prop can’t be completely feathered.
Secondly, it was burning the oil that was pouring out of the crankcase. The DC-6 can dump its fuel, but that wouldn’t have done any good at all in this situation
@@Idaho278 Thanks, and even if the prop on an engine of a multi-engine plane isn't feathered, can planes still fly okay despite the extra drag?
@@tungstenkid2271 absolutely. They can fly with the prop unfeathered but it’d be a lot of resistance for sure.
Also I guess the prop will still feather with the extinguisher pulled, so I wonder if the crank case being broke apart like that completely flushed the oil it needed to feather.
@@Idaho278the propeller can absolutely be feathered after activating the FWSO. Maybe don’t comment if you don’t know what you are talking about
@@Idaho278there is oil reserved for feathering in situations like that. It’s a standpipe oil system
If you don’t feather the props immediately after engine out on dc-6 or 4s your F’ed.
I know the video contains mature subject matter and i dont mean to sound insensitve, but i own the DC6 for MSFS, im actually flying the northern air cargo DC6 as we speak, how do you get the damage modeling like the wing failure with the wing coming off ? Is it just editing or is there a mod for this ?
Through editing and special effects. MSFS doesn't inherently support detailed damage modeling for aircraft as far as I know. Thanks for watching my channel!
The strobe flash edits are unwatchable. Don't do that.
Why didn't the captain get clearance to climb? When flying ancient death traps always be ready to climb in case of fire.
Is this real?
I’m not a pilot but have watched many of theses air crashes. It appears that no matter what happens they always and I mean always blame the air crew in part. Is it just low hanging fruit for the insurance companies. Dead aircrews can’t defend themselves. Here the engine catches fire and burns the wing of and some how it’s part the aircrews fault. They will pick fly shittt out of pepper , finding something the aircrew did that wasn’t text book. It’s wrong.
EEEEEE mon Ick not emin nack
I agree with the fatigue issue and other human factors. It is only the crew themselves that may be responsible for flying while not fit, so they are not exonerated. They are to be blamed.
The video correctly cites the NTSB report - Unfortunately the NTSB conclusion and the cause of fatigue fracture is incorrect. I conducted a forensic engineering failure analysis of the connecting rod in 1999. The corrosion pit that the NTSB thought was the initiator was just one of dozens across the entire fracture surface and had clearly occurred post fire. I have seen this phenomenon many times in aircraft fires.
The actual cause was a bent connecting rod, which occurred sometime before this flight due to hydraulic lock during start.
The engine was very low time out of major overhaul.
Perhaps the low time engine gives the flight engineer a false sense of security about the engine. Unfortunate that in 2-3 hrs of operation he didn't notice any anomalies until the engine starting chucking parts with resultant fire..
@@richceglinski7543an engine out of overhaul could be the most dangerous time of all, until it’s been run on a few times. Mistakes usually shows themselves quickly.

@@miragesmack007Like who did the work. I do all the maintenance on my vehicles because of my lack of trust with most mechanics
Just discovered this channel, looks pretty good. Will start the proverbial Binge.
Fantastic to hear that you've discovered my channel and are planning to binge-watch! I hope you find the content both engaging and informative. Enjoy the videos, and feel free to share any feedback or suggestions. Happy viewing!
This accident covers a DC 6. The DC 4 had large diameter cord-reinforced rubber-fuel lines in the wheelbay. These were sensative for embrittlement, and hence fuel leakage. Fuel spill can cause a puddle of fuel in a hot area.
I donot know how the fuel lines of the DC 6 are routed or materialised.
These machines need specialised mechanics and a lot of attention. (= money)
Absolutely agree sir !
Yes, too many moving parts.
It’s important to put the DATE and location of the incident…..
You're right, while the date and location is mentioned in the narration, it's indeed significant enough to be highlighted with a visual text in the video as well like my other videos. I appreciate your helpful feedback!
Not bad at all. Good luck with your channel!
Thank you for the encouragement! I'm glad you enjoyed the content. Stay tuned for more, and thanks again for your support!
This is why the engines on modern planes are mounted on pylons under the wing. They are designed to fall free of the airframe if a fire can't be put out.
How do you customize flight sim like this? Pretty cool looking.
The hours this crew were expected to operate with several take offs and landings, seems to be too much. Was this duty day legal?
Can’t recall the exact number, but 3 man crew duty days were legal yet insane!
20 20 with Hindsight, they say , prevention better than being cured . .
I had been flying in the area for several years just before this crash. I can’t remember if I read about or heard about the first aborted landing attempt.
There should be plenty of evidence on the CVR if available. I don’t know where the audio from the inter crew discussions was pulled from for this RUclips video. It would be monumental if they included it their next video.
Thank you for the video. The flicking between views needs softening as it’s quite difficult to focus on.
Thank you for your feedback. I’ve made some adjustments to the transitions in my latest videos and am always working to enhance the quality of my content. Your input is much appreciated!
Just came back to this video to say thank you for continuing to provide exactly what I said in comments here, that I would love to see more of 😀. This channel is one of my favourites as it offers something different plus a lot of videos of events I haven’t heard about. I hope you continue to gain subscribers and grow.
I get weary of hearing pilot error. Wish some of the smart people would be under unusual circumstances and see how awesome they were. Isn't it convenient for all involved to blame someone who isn't available?
My man is struggling editing the audio 😂
Maintenance is also to blame for failing to find the corrosion pit that led to fatigue cracking.
Alternatively you could say “I know nothing about aircraft maintenance.” Even when changing jugs you typically dont do NDT inspections on crankshaft components unless specifically required. Not to mention this was an engine freshly installed from overhaul. Manufacturer or repair station error.
You don’t get into engine internals unless a part times out or inspection is due. It seems the rod was fatigued from cranking while hydrolocked, which could have easily happened that morning on startup or even in the days prior. You don’t disassemble the motor every time you fly. Lay off maintenance.
