Does anyone else never buy things sponsored on UA-cam (but look for better alternatives)?
I wonder if having a fuse on the opposite side of the blade that broke so it detaches and compensates the imbalance would work.
Thank you Petter for your excellent work getting the word out on aviation safety! Unfortunately, the FAA & NTSB have had many problems with competence, corruption, as well as the "normal" bureaucratic issues. Hopefully it will change. We'll see.
Anyways, they don't wanna fix these covert issues that they can use at some point in the future to covertly murder someone or many. Is why when you reach out to them, they don't fix it. And this is one of a lot of things they know to target others for murdering.

I am an airline powerplant engineer working with LEAP 1A engines and currently preparing our entry into service for the LEAP 1B. I did have the training for the 1A a few years ago, and the load reduction system was not highlighted during the training. I will highlight this issue to CFM and check if the 1A has a similar fan design. If so, I will escelate it to our flying crews as well. Thanks a lot for your work.
Thank you for warning CFM and another people
I'm a flight crew on the A320, would really appreciate it if you find any information regarding this
Be careful and keep records as higher ups probably know about this but aren’t acting. You can get hostility, but it’s a very important issue. So protect yourself and keep records, in case you have any issues after raising it.
…call me a conspiracy theorist but have you ever wondered how those long lasting contrails are created that criss-cross the skies of all major parts of the planet? Do not forget that during the UN Climate Change Conference (COP21) in Paris held in December 2015 one of the 17 sustainable development goals promoted is to reduce solar radiation with the help of stratospheric sulphate aerosol injection… this stuff is mixed into the jet-fuel and can be activated by ground based Next-Rad radar stations… go to the Aviation Herald and scroll through the last 36 months of incidents reporting -smoke in the cabin, fog in the cabin, burning smell, smell of potential electrical fire… or check the recent incident of Swiss International Flight LX-1885 from Bucharest to Zurich on December 23rd 2023… one flight attendant was killed by the toxic smoke… IT IS NOT HYDRAULIC OILS LEAKING INTO THE BLEED AIR CIRCUIT. Okay dear fellow aviators, do your home work.
This is the stuff we need!
It's not often I see a UA-cam video that has a genuine chance at saving lives, but as an asthmatic who would have a Bad Day if this ever happened on my flight, the life you save just may be my own. Thank you for always advocating for pilot and passenger safety.
Thank you for your kind words
If your pilots are out cold I don't really think your asthmatic issues are going to matter all that much lol. When you're in the sky the only way out is down, and with no pilots the plane meets ground part won't involve any wheels.
it is one of the best channel about aviation. video quality, good narrative skills but also real work and knowledge in behind
@@MentourPilot Petter, I'm going to be "that guy" in the comment section. I saw that you corresponded with the FAA in January, but the actual date was not revealed. Was this early in January or at the end of January? In early January the leadership of the FAA was operating under the policies of Secretary of Transportation Buttigieg, whose focus was on "racist" roads and bridges. After mid-January the FAA began operating under the policies of Secretary of Transportation Sean Duffy, who was sworn in on 28 January. Please try them again.
Excellent analysis, Petter! I’m going to contact my congressmen. It baffles me how a simple bird strike can turn an engine into a formaldehyde fog machine blasting toxic fumes directly into the cabin or cockpit, but it is even more confusing that no regulatory boards seem to think this is a serious issue.
I agree!
Thanks for your help
Choice between trusting a regulator who is ignoring the problem or trusting a Senior Line Captain who is giving us the information before it takes a sober turn....yeah I am gonna trust the Captain before the regulator on this one!
And maybe now they need to start sending emails to the Senators and Higher personal in other Governments.
I would trust the people who know what's going on, and that's NOT the government or one of its agencies. Government critters may (or may not) have some general knowledge, but when it comes to the details...
💯
@mrxmry3264 Typically governments ask multiple experts to know and that works quite nice.
Unless the government is corrupt by some companies.. ya know like the USA government.
This is chilling. The fact that both the american and european agencies tasked with investigating this issue are "nah bro, it's all right" is absolutely mindblowing.
As you mention in the video, this is eerily reminiscent of the cargo door problems of the early DC-10 that led to the tragedy of Turkish Airlines Flight 981 -- even down to the issuing of a "bulletin" that proved to be ineffective. You are doing something very important by bringing this to the attention of the wider aviation community. Thank you!
Thank YOU for watching and helping me spread the word
💯
I read some 20 years after the accident that it turned out that there was an explosive in bin-5 and it was not related to the operation of the bin-5 cargo door.
I was literally just thinking about that gentleman's agreement when he referred to it. CHilling.
@ I closed many bin-5 doors on DC-10s as a ramper and each time, mechanics were there, as Douglas added a window under the door with the metal bar confirmed as closed and locked. It was only revealed some 10-years ago, decades after the accident, that it was not the door design. Yes ... odd.
Just a little over a month ago Swiss Airlines experienced the first fatality in the airline's history caused by a very similar reason - smoke inhalation due to an oil leak in the engine. One of the cabin crew has unfortunately died because of this.
It is not directly related, as it was an A220, but it shows just how dangerous and serious smoke in the cabin can be, the authorities decision is truly baffling.
I'm surprised there are no fine particle detectors in the bleed air system. Seems like a no-brainer.
Look up aerotoxic syndrome, and maybe avherald page. There’s many similar incidents, usually the authorities don’t take them seriously. The passengers are happy as long as they make it to the connecting flight. Never refuse a medical check after a fume event.
Wow, very little information was released on this one ... I heard about the unfortunate death of a crew member, but I suspect the press really don't have a good technical edge on presenting what really happened. It seems to me that these processes on bleed air should apply to all similar engine types.
But wait the Pratt & Whitney engines aren't equipped with LRD
Wait didn't swiss air lose an entire flight out of Boston years ago in a fire
I have several hundred hours flying these Southwest 737 MAX-8 aircraft. I immediately forwarded this presentation to my SWA comrades after viewing it. Thank you for promoting aviation safety. I often use your presentations at my flight school and aircraft dispatcher school. This is top-notch instruction!
I could say they are simply irresponsible, but the fact that they removed their own investigator from the case, well, I interpret this as they are actively trying to bury this.
Thats what I’m afraid of
@@MentourPilot Also, the fact that a leaked memo is part of this story suggests that there are worried insiders.
Murphys law, it is not a question IF but WHEN this will bring a plane down. Needs to be addressed and fixed immediately.
My thought exactly
I have a feeling he is releasing this now because it already HAS brought a plane down, in SK.
I hope this video goes viral, and not just because I really like this channel.
You’re absolutely right, this is a very lethal and serious problem, it needs attention.
Indeed
@@MentourPilotJust finished the video. Your fictional scenario is chillingly likely, and rings really true. I can’t find a fault in your logic. I just hope someone listens before a major crash happens because of this. I guess I don’t know all the details, so maybe I’m not really informed enough to make a decision, but I would personally have grounded all relevant planes pending the software updates, if I was in charge.
Edit: to the keyboard warriors who claim to know better than a seasoned line pilot, first, LOL. Second, it’s very much well known that with respiratory threats, you lose consciousness a fair bit before it is lethal. Which is accurate enough in the hypothetical scenario. 37 seconds of breathing those particular chemicals, especially while stressed (which significantly raises respiratory rates, reducing your resilience against respiratory threats), will absolutely knock you out, at least as far as useful consciousness is concerned. Soon after, death follows, and even if you get your mask on in time, you may still die later from complications, as one of the pilots from the first flight ALREADY HAS.
You can argue with Petter, despite looking silly.
You can’t exactly argue with a gravestone.
@@mycroft3322 no, it is not. Petter has a very deep misunderstanding of 'potentially lethal levels in 39 seconds'. This does not remotely mean you could be incapacitated in 39 seconds, it means if you get your mask on within 39 seconds there is _zero_ chance of it k!lling you.
@@mycosysYou want to be s passenger in an airplane with an engine failure and the cockpit filled with dense smoke, so the pilots can't see the instruments it outside soon after takeoff or just before landing? I don't. Taking your headset off and putting on a mask, goggles, and your headset again will take say 5 seconds, you want the pilots to stop flying during a critical phase of flight? The recommendation to turn off the bleed air to the cockpit during take off and landing is a simple and practically free fix, why take the risk?
@ learn to read
As pointed out by others, please look into LX1885 A220 which suffered an engine failure with fractured shaft and one cabin crew dying after several days. Not a CFM, but I'm surprised that this accident over Graz in about 12000ft did not get more coverage. Thank you for your amazing and dedicated work.
I will have a look at it.. we discussed it in the prep for this video but since it was a completely different system involved, we left it out
@@MentourPilot It is accurate that the Swiss event didn't relate to the LRD system. There seems to be a suspicion about a bad PBE in that event, although recent news raised concerns about a possible PBE swap during investigation, which would make one think about what's really going on. Nevertheless, many other fume events are happening around the world due to different reasons. Airbus has acknowledge, for instance, that oil leaks in the APU are the most common reason for such events in the A320. Often, these leaks get stuck in the A/C packs, and get released a few hours later, during the final stages of a descent/approach, which is a critical stage of flight. The overall message here is, although there is indeed this very specific issue with the LEAP engine, other issues have been causing similar problems in different types of aircraft. Maybe the reason why FAA and EASA are denying addressing this specific LEAP problem is that they know they will be waking up a sleeping giant through the entire industry, which is the fact that bleed air goes inside the aircraft without any kind of barrier or filtration. I have addittional information and relevant documents if you would like to dig deeper. Thank you for an excellent job in raising safety awareness!
This may be a way-too-obvious question, but wouldn't a common HEPA air filter prevent a lot of the toxic smoke from entering the cockpit? I know that the recirculated air is filtered, but it appears that the incoming bleed air might not be. The filter would eventually get saturated and clogged, but the oxygen masks will be on by that time.
There are ways to handle a saturated filter, but the most primitive one would be best: have the filter on the outside of the vent cover (so the filter is in the cabin), and that has 2 advantages: the pilots can easily see that it has become saturated because the normally-white filter has turned black; and if it needs to be removed quickly, most filters are made of weak materials, so it would be easy to simply rip a hole in it by hand, or have a pull-tab that cuts through it. And there can be an automatic mechanical mechanical bypass caused by the pressure difference if it gets clogged.
Yes! Please do Pétr! I asked the question at the time of the event. That had to be some toxic stuff; and why didn’t he don his PBE?
@@chrisedwards3866it’s not only the particles. The toxic gases are the issue. Formaldehyde is extremely toxic. A particle filter wouldn’t help much, and how much capacity would this filter have to have before it gets saturated.
I for some reason thought this was going to be about the recent crashes, but I definitely am happy about this kind of video. I think it’s great to bring awareness to systems like this. I look forward to watching it!
Glad you are here!
Hey @MentourPilot , could you cover Gol flight 1907 ? It is really close to me as a friend was on the flight, and I would love to see you covering it.
Why would it be about the recent crashes when we know what caused them and it wasn't any system.
The state of affairs and priorities of the FAA over the last few years might very well BE a contributing factor.
Perhaps money is a playing factor in this issue, like in some other events related to safety/design solutions, that proved to be wrong/bad. Why not dumping the oil into the exaust / fan duct? The pollution of the raw oil dumped is negligible compared to the total atmospheric contamination (and perhaps less hazardous) than the burned mix. About the regulators: besides safety, other major 'concerns' are usualy addressed in their's "everyday life"... To you: excellent choice/warning/concern/'wake up gentlmen" video. Thank you!
Petter, you’re a brave man speaking out about this. But you’re also a good man for speaking out about this. I hope this causes enough noise for Boeing to take a look at this system.
This is groundbreaking work you're doing, Petter. Sincerest thanks for your hard work and for continuing to share!
I’m glad you find it helpful! 🩷 thank you for sharing
A BA captain eventually died following these 'toxic fume events'. It is something the industry keeps very quiet about it. It's nasty stuff to inhale - organophosphates
Was that on the BAe146? Flew once as a passenger - smoke at startup was clearly visible in the cabin for a few minutes, but all cleared before takeoff. Quite different if you breathe this stuff several times a day for years...
where would the phosphate come from if its burning oil? its likely just regular smoke and soot from incomplete combustion of oil&kerosene
@@peterheinzo515 I would have thought impurities?
@@lardo666 ,lots of aircrew on the 146 ,ended up with cancer ….
After covid you'd kinda expect hepa filters on ac air. Pretty sure they block smoke and particulates
Thanks so much for being so vocal about this, hopefully this can end with the good scenario where this problem gets fixed without any loss of life.
I hope so too
I teach engineers on LEAP 1A and others engines too. This is the first I have heard of the LRD and what happens when it triggers. Well delivered Sir
Do you know if this issue could occur in the same way with a LEAP 1A on a Neo?
One thing's for sure: the airlines themselves can implement the temporary fix outlined by the FAA investigators, in consultation with Boeing and CFM. They don't have to wait for the FAA to get its act together. The procedure doesn't sound too complicated or too expensive and seems to greatly reduce the risk of toxic levels of smoke entering the cockpit.
Yes, but they always follow the regulator and rarely move outside of what they say.
Already saw this on Patreon, and now I'm happy that also others can watch this, hopefully increasing awareness on this issue. Thank you for the amazing job you're doing, Petter. The world will hopefully become a better place thanks to people like you.
Thanks for your support!
Petter, you're at a unique position to bring issues like this to light, is good you have done so. Will certainly help you sleep better at night if there IS a tragic accident. Love your work!!
Yes, that’s exactly how I felt when I saw this..
if I DIDNT do this, and something would happen, I would never forgive myself.
@@MentourPilot Exactly. I've come to cross roads in my life, where i look down two paths, A) I raise the issue, and catch a LOT of grief for doing so (and question myself too, maybe i'm making a big deal over nothing?? maybe i'm just wrong) or B) do nothing, stay quiet.... B is the easy path, but if anyone is ever hurt because of B.... I know I could never forgive myself, it would always haunt me. I just dont need that on my soul. I'll take A over B
Being able to look yourself in the mirror in the morning and not be ashamed of who you see, is one of the most valuable things in life
When you quit piloting and said you were going to commit yourself to safety (my bad paraphrasing), I didn't quite understand, but this sort of video makes it very clear. Thank you Petter!
Bravo, Sir.. "An ounce of prevention is worth a pound of cure" Thanks for this and for all your work. Wishing you and family all the best.
Like always, better than any Netflix documentary. You and your Team somehow still manage to step it up in quality Petter!
A bleed off take off seems to be the reasonable thing to recommend while waiting for a definitive fix. You have all my support and I will speak about this with my coworkers that are on MAX. As per our airlines SOP taking off with bleeds off is at captains discretion.
Thats exactly my view as well
One question I have about this: shouldn't this also apply to the landing?
Why is the government “slow walking” this information? Absolutely love what you are doing here. Let’s ahead of these potential disasters!
The priorities for the FAA, and other federally-directed agencies, over the last few years might be a contributing factor.
@@cindyknudson2715the priority has always been safety. If anyone is trying to insinuate that the priority is DEI, then they need to stop trusting internet memes pushed by utter morons who profit by lying to you.
Given President Elon Musk and his desire for reckless cost cutting I fear that safety culture and regulations will be thrown out with the bath water
Because they dont have a solution most likely.
Petter, I completely agree, this is a very serious issue and should be addressed. My work involves a lot of human performance elements and what I see here is that the recommendation that depends on the pilots putting on their masks immediately assumes that they will do this immediately and they are not already loaded with other tasks, and does not address the huge issue of smoke in the cabin and the visibility issue as well. I think it's always better to engineer systems around the humans rather then depend on the human to react after the fact. It's best to redesign the system so that engine failure does not fill the cockpit with this oil or smoke. Since this requires resign, adding the other procedure of turning off pack1 during takeoff is a good interim workaround because at least the human will be performing this task during routine preparation and not while already overloaded with other tasks and experiencing an engine failure. The FAA is generally very light-handed in adding regulations because many lawmakers consider regulations to be a bad thing that hampers companies
Your videos are so finely crafted that even a person with no engineering, flight experience, or advanced education can understand them. Thank you to you and your team for your dedication to safety and education. I truly hope that your message reaches those who have the power to prevent catastrophe (and that they actually take measures to protect all who fly)
17:45 that's terrible, I thought UPS 6 aftermath addressed the smoke-in-cabin issue. That's an incredibly important issue. Why we still underestimate the impact of smoke!
Hi Petter, I forwarded this to the London-based aviation journalist at the Wall Street Journal… If you follow up personally I’m sure that you can start a conversation.
Sadly, given the state of the US right now I wouldn't expect much action on this 😢
100% agree with you, this is a fatal accident waiting to happen. Good on you for drawing attention to this
As a software developer my main thought from the description of the issue onward was. "Why doesn't LRD activation also perform bleed air shutoff for that engine?".
I lfy for a European operator of the A320 and A32 NEO - we conduct all take-offs packs off as a standard. Packs are switched on after initial thrust reduction, about 1000' AGL.
That sounds very sensible. I imagine big birds fly higher than 1000' though.
@@tehoro68931000 feet isn't much (300 meters) there are still vultures and eagles, sea birds (albatross, seagulls), geese and migratory birds too ... But at that altitude the plane would be stabilized (or in a less critical phase), giving the pilots enough time to put in the mask. By switching on the packs later, the A320s possibly have slightly less danger with this system.
BUT as Petter says, that's just not enough, in an industry where safety must meet high standards, we can't just rely on adding pressure to already overwhelmed pilots during engine failure.
PW1100G or Leap-1A?
@amcconnell6730 - I’m curious why your operator chose to make Packs-Off standard procedure? I’ve always thought about it in the context of obtaining slightly more thrust for performance limited takeoffs. I take it there must be other considerations.
@@ppeterson9359 Increased power.also means you can have a higher reduced thrust, and thus save fuel on every take-off. :)
Good idea to be pre-emptive!
I hope so
@MentourPilot If I'm ever unfortunate enough to be in an airplane that's going down, I think one of my thoughts would be "I wish Petr had made a video explaining whatever is the issue with this airplane/pilot and then this would not be happening" 😂
Agreed, and I think that the FAA is trying to suppress these accidents a bit because of the state the industry is in at the moment. After all the problems with Boeing and the recent three accidents in the first month of the year, it might be that the FAA fears that a detailed report might be the final blow for Boeing, even though Boeing is NOT to blame for this, and cause severe harm the rest of the industry.
You always report the facts with truth, honesty, and integrity. I support your information and opinions one hundred percent!!!
Proactive approach is commendable 👏 👏 👏
I hope it will work
100000% agree with you on this one. Frustrating they seem to be waiting on….. something to happen. Very unfortunate. Great video to bring awareness.
Hopefully it helps
Hi Petter!
I saw the community post yesterday and i have been non stop refreshing your channel page for this
I have been watching the channel for 5 months and have already watched most of your videos. Its just quality
Have a good day Petter (and everyone else)
Why would you refresh constantly when he released a date and timestamp for when it will be available?
Its nice to be as early as possible@@mangos2888
Thank you, Petter. Your commitment to safety is unquestionable here. I will send this to my Congressman immediately.
I recently wrote a paper about how problematic the MCAS system was with reference to these crashes for my college project. My focus was on the duopoly of Boeing and Airbus in the aircraft manufacturing sector and how stifling competition like this can lead to hasty launches like the Boeing 737-Max in response to Airbus 320 neo. I'm so glad you've made a video on this topic, this needs to be discussed.
Not sure even "Sully" could have recovered with the added smoke and additional time (neither he nor his copilot had) dawning masks. I read he's still giving lectures on global aviation safety. I hope he's up on this one. Great presentation!
Thank you for being an excellent advocate for crew and passenger safety! I hope this video will cause a stir so the agencies in charge will get off their rear ends and do something.
Hopefully with all the comments and like the video will go viral. Even big media should be aware of the work youre doing! Great video. Will recommend it to my friends/ family and others. Stay happy and enjoy every single minute with your family! Youre a great producer! :)
Thank you so much for your support
I love how clearly you explain each component in both the sequence of events and each component on the planes! This is a fantastic video, and I hope this message gets to the right people 🙏
With the current state of the air industry in America right now, this is very concerning information!
Working with both fuels and lubricants at university's research lab, I can definitively say that being close to the burning of fuels and lubricants together is nasty. It's a bit like being too close to a bonfire with an acrid smell and very eye irritating smoke. Most unpleasant!
Very carefully and well presented description of what really does look like a problem that needs faster action to be required.
The video takes a little while to get to the issue, but by the end it is absolutely engrossing.
I fear that little will happen right now as the US government is currently in an induced turmoil, but maybe there can still be some people able to take action.
If people in the US do want to contact their representatives, there is an app called “5 calls” that helps you find them and their contact info. Phone calls are MUCH more impactful to them than emails (which are ignored).
In your video you said i could find the sources in the description. THEY ARE NOT THERE
(Sorry just had to write that in capitals) keep on the good work
The problem with Boeing is that they don’t do anything that involves safety unless forced to. That’s the best thing about Airbus-they do that much more often.
Thank you Petter for your excellent work getting the word out on aviation safety! Unfortunately, the FAA & NTSB have had many problems with competence, corruption, as well as the "normal" bureaucratic issues. Hopefully it will change. We'll see.
All we can do is to spread the word
With DOGE in charge of destroying regulatory oversight (and FAA mishap investigations of SpaceX accidents being one major motivation behind this drive), do not expect positive change.
The title should say: "and nothing is Boeing done"
Thx for coming to my TED talk
I am still watching the video, but I think this is a great approach on increasing safety. Well done.
I will be sharing your video and contacting TSB and TC about this issue. Canada has smaller agencies, but sometimes, outside pressure helps fix issues.
Kind of surprised that CFM and Boeing didn't consider the LRD activating could cause the bleed air system to be flooded with smoke... I'd have through they would have at least had the engine loaded with vibration sensors which could detect an LRD activation and by extension disable the bleed air system for that engine...
I think THATS the software change that’s needed
After this video, I truely believe that Boeing engineers are out to get us. When they were designing the Max, they are like “Hey, would it be cool if I add this failure chain that will guarantee deaths and it will be hidden from the regulators just enough to get it pass? Let’s start a pool to see how many of these are activated”. Engineer one then proceeded to add MCAS while laughing manically. The second engineer went with this thing where I’m going to poison and blind the pilots and passengers.
Critically important info, thanks for you work!
Thanks! I hope it can help make a difference.
@@MentourPilot You dp
Thank you Petter! This is probably the most important and thorough aviation video of the year! I'm kind of not surprised that FAA is not doing what they should.
Can't believe that these type of video are actually free to watch
They are not free. You are the product
You are part of the demographic that watches these types of videos. Engaging in it makes the audience grow. more audience means more sponsorship money and more people willing to donate.. even if you aren't paying money you are adding your own small brick to that wall.
Why?
NTSB senior examiner in the DC crash was pretty emotional in the second or third briefing. At one point he said something to the effect of “we have hundreds of unimplemented safety recommendations. If you want to do something about safety, encourage regulators to implement our recommendations” (not in verbatim, from memory) when he started to get upset with the media, and later walked off upset. It was a bit more emotional than you expect from an official, but a very powerful message. Investigators tell you why an incident happened, and how the risk from such incidents can be mitigated. If you don’t implement the recommendations, you’ll get more preventable incidents and with needlessly harmful outcomes. If you refuse to learn from the past, investigating it becomes pointless.
This needs to be heard.
Well, you’ve thoroughly scared the crap out of me, but I’m grateful for you raising the alarm, and I pray this can actually save lives.
Maybe it's just how clearly you explained it, but I am shocked at how no one in the design or manufacturing process of those engines could have realized that intensely heated oil would be leaked into the air conditioning system 🤯
With airflow that is going through the engine it is quite easy to assume that it would mostly go through and the amount sucked with the bleed air would be minimal.
I think it will be very interesting to hear how this system affects the A320, I would be entirely unsurprised to find out that it doesn't have the "vents all oil into the cockpit" issue and the worst case is then what happened on the first flight discussed (non-lethal smoke in the passenger cabin). Potential single passenger fatalities are treated one rank lower in aviation risk assessments than potential flight crew fatalities, so given the already low probability of significant engine damage due to bird strike that probably would have caused this behaviour to be acceptable during the certification process. The LEAP-1 was initially developed primarily with the A320 in mind and then slapped on the 737 as an emergency measure after all, so I'd not be surprised if this issue simply slipped through the cracks... it's an interface problem between the engineand the airframe manufacturer, which is prime breeding ground for problems to happen.
This is excellent information, thank you for highlighting it. I also have to compliment you on the outstanding graphics in these productions. They are only getting better as time goes on.
I worked on an FAA project to improve the Airworthiness Directive process. The Administrator can act without any public or industry review to initiate a mandatory upgrade. Immediately, if necessary. But not an acting administrator. And a new administrator is very unlikely to take industry-unpopular actions. (Based on new administration priorities). So I’m afraid we won’t see much on this, despite rhetoric to the contrary about “safety.”
I hope you are wrong even if I am afraid you could be right...
Sadly, I fear you are correct that, officially, nothing will come of this in the U.S. But perhaps the Europeans will take action. And if individual airlines are made aware of this, perhaps they, too, will alter their training and procedures. And it's possible that Boeing will act on this too.
I also fear that you are correct and we are returning to a so-called "business friendly" approach, one in which regulators are afraid of rocking the boat, even when they know they should. The overall policy direction takes precedence over each individual action. We saw the same during the Bush era with OSHA and EPA, where the presidentially-appointed administrators wouldn't take the actions that their agencies exist to take, because the presidential priority was to reduce oversight; but they couldn't change any laws so they just stopped the enforcement overall. Many workers got life-ruining or ending injuries during that period.
The amount and burden of oversight is a topic that is worthy of debate because it is possible to have too much or too little. But usually the public (and publicized) version of the debate is done without regard to any facts and is just a bunch of grandstanding, red herrings, and hypotheticals. It's much easier to fearmonger with hypotheticals than to study the complicated reality.
Still why previous one did nothing? Don’t push blame to new administration.
I think you mentioned a key point here: unlikely to take unpopular action.
There’s two flaws with that:
1) the FAA uses a blame culture, and retaliation on those suggesting actions etc that improve safety.
2) the FAA shouldn’t care whatsoever it’s popular or not with businesses lobbyists and politicians. They have one job: ensure safety in aviation.
But hearing this explains a lot about the problems with US aviation.
Thank you for bringing this to the attention of the public! Hopefully the regulators will now be forced to act, as well as explain themselves for their initial dismissal of the issue!
An Oil Mist would have been "Carbureted" into the A/C Compressor however in order to be able to inhale such a mist it needs to be further 'Aerosolized' which occurs when the Oil is heated beyond its Smoking Temperature. Aerosolization can also occur during high pressure spray through a Nozzle however I do not believe that occured in this case. It was the heating of the oil that caused the Aerosol Smoke [Haze] to form. It is this Aerosolized Oil that presents the Inhalation Danger. I realize this is a minor difference however it does demark the point between 'messy and deadly'.
That would give a plausible non curruption reason for the downgrade.
If the 39s analysis would be based on wrong assumpion.
This is a very important video, and one that I truly hope gets the audience it deserves. Kudos to you and your team, Petter. Using your reach for something proactive like this is TREMENDOUSLY fantastic.
I doubt I can afford you, but how much would it cost to have you accompany me through life and point out, “make a note of that; it will become important”? I could really use the help.
This needs to be covered by the Times or other major news media outlet ASAP, preferably before we get any casualties. Kudos to Petro and the rest of the team for shining some light on this major oversight bordering on criminal negligence on part of the regulators.
It seems odd that the LRD itself doesn't have some kind of signal trigger (especially considering that the oil dump is an expected side effect). Seems pretty obvious to tie things like cutting off the bleed air to a signal tripped by the LRD breaking?
Yep! I agree
@@jamesdutton4526you should be able to detect a loss of oil pressure though when the system activates and use that as a possible trigger.
I am Austrian and have spent several vacations in and around Salzburg. And when the "Alternative sequence of events" started, I immediately got goosebumps and just thought to myself "left enginge fail at rotate"... Boeing, CFM, FAA, NTSB: Please get started and avoid a "bad outcome" with these LRD and the smoke. Thank you all, especially "Mentour Pilot" - great work!
Yes, it's out, been waiting since the post yesterday.
I hope you will find it interesting
@@MentourPilot I am only 7 minutes in and it is already really interesting.
Very well put together. We appreciate all of the hard work you put into this craft . I hope this gets the attention of the FAA and it makes them reevaluate their position.
I hope so to
I'm surprised that they didn't already have the LRD set up to automatically trip the PRSOV for the affected engine. It seems like a simple and reasonable thing to do.
Same for me - it is actually obvious, that if LRD activates, oil will *always* be dumped to a compressor, and by extension, into bleed air system.
Given how ineffective the FAA has been with Boeing, I simply wouldn’t go anywhere near a MAX aircraft no matter how much you paid me.
Looking forward to this! I hope you and the family had a lovely new year and Christmas Petter! We need to have a coffee the next time you’re near Cambridge or London, or a catch up soon!
Sure Samuel
As I guess your contacts to Ryanair are still very good: Will the chief pilot of Ryanair push for a change of their SOP for their MAX fleet (and maybe other aircrafts)? Or do they also only act if EASA calls for action?
Love these videos! Thanks :)
Fancy seeing you here !
You're welcome!
Your absolute best video ever. You may just have saved lives!
Incredible video Petter, maybe you should consider reaching out to media outlets to bring more attention to this issue and pressure regulators. Thank you for making this content freely available!
You mean regulators like those Trump fired leading to an immediate flurry of disasters?
I've been watching your series since episode 1, and this one is by far my new favorite. Your scenario at the very end hit me hard and, if things are not being done in a timely manner, that exact scenario potentially will happen! Great video as always, I always get really happy when I see you posting your videos ❤️ Excellent job by both you Petter and your amazing team ❤️
Greed and corruption, big businesses with power and money plus toothless regulators.
I really hope you are wrong…
"Defanged regulators" is a more apt description. The FAA used to be a role model across the world, and it wasn't spontaneous developments that changed that.
Hello Petter looking forward to another great story. Just commented even before watching it. I just love this channel ❤
Thank you so much for your support!
POV: You're at the airport and you see that the plane you're gonna board is a 737-MAX:
aaaaaaaaah aaaaaaaaaah aaaaaaaaaaaah eeeaaaaaaaah!!!!
Boeing executives: Why are you running? WHY are you running?!
If you’ve spent any time in Havana, you know how common turkey vultures are. Sadly, one reason they are in urban areas is all of the feral cats and dogs running around. Cuba has no sort of animal control services, being a third world country. 🦃 So there are a ton of feral animals in Havana, who eventually die of disease or starvation.
Another thing to worry about on departure! 😬
This is absolutely a great direction for your channel. There needs to be answers from the FAA on these recent mishaps and the uptick in controller induced near misses to commercial and GA. I hope some of the changes to reprioritize performance based staffing will result in positive changes.
Wow, this intro SLAPS 😮🔥
There are several options here:
- Some kind of sensor to detect when the LRD has been activated and immediately cut off the bleed air to the pack.
- a smoke sensor in the bleed air line to vent the bleed air to the outside when smoke is detected.
- automatic engine shutdown when all the oil is gone or when excessive vibrations are detected.
How fast do you think this software could act ? 39 seconds is so few
@mrxmry3264 when engine fail or fire detected, shut off the corresponding pack... This do not require any new sensors or systems.
@@HongruiFeng I'm not familiar with the intricacies of the electronics of the 737 family, but I'd be interested to know whether any of the cut-off valves have the ability to be controlled through the main flight software. I'd imagine some of them are closed-systems, where tripping a sensor will automatically close the valve and the only interaction with the flight computer will be to alert it that the valve has triggered. Same with the packs, if they're controlled directly through the pack switch(es) in the cockpit then is there even the ability for the software to override it? It would seem like a potential added failure-point if so.
you did an absolutely fantastic job of both explaining the issue and alerting us to it
keep up the good work
Read the description, saw "whistleblowers" & "Boeing", and I'm already anxious. Thanks to you & your team, though, I know I will be able handle watching this.
Brilliant Petter. Excellent video and well explained. I would not want to be a senior person working in any American Government organization at the moment.
I wonder if working towards changing the length of CVR from the length that 1950s mechanical magnetic tape technology provided of 1 hour and including something like $10 100GB usb drive would also help the industry.
It absolutely would. Too bad American regulators are still the ones who grew up with that reel-to-reel tape.
@@doomsdayrabbit4398- The original 30 minute length was a compromise reached between regulators and, believe it or not, pilots' unions - who initially opposed CVRs completely on the grounds of employers using it as a "spy" in the flight deck. I believe this has been expanded to two hours in more recent years - again another compromise. The issue is not intransigence over modern vs. older recording technology, regardless.
@@joehoy9242 Well maybe if we had better protections against employer retaliation...
Id say it should rather be replaced with 1 traditional black box, as well as dusins of tiny "black boxes" that are tiny, float, and have basic location gear. theese could be placed all around the plane. considering how tiny a ssd is, and how robus it could be, with no moving parts it could be basically cast into a material. and some sort of passive location tech could help locate them provided you are near them. and then its just a numbers game.
Thanks for making this video. Knowing what you know and have just done, hopefully, even if it only saves one life, is an amazing and valuable quality of foresight and I hope they hear you loud n clear. ❤️
Sadly with the new resident of the Oval Office at 1600 Penniveined Ave in Washington DC urging traffic controllers to quit 'and get a higher paying private job' as well as hacking and slaying at our government in silly ways, I doubt we'll see them get sufficient focus on this issue to make any recommendation or rules.
Thankfully there's still Europe, although the fact that they also buried their head in the sand so far is baffling
Sir, I'm not a Trump lover by any stretch, but his focus is on getting better qualified personnel into those positions. His focus _is_ on safety. And he's not "hacking and slashing the government in silly ways" either. He's cutting wasteful spending and corruption out as expeditiously as he's allowed. I'll say again, Trump is not my guy, but I also don't care for the way he's constantly attacked with half-truths and outright BS.
@@normie2716 By attempting to freeze ALL government fund, temporarily collapsing the US government if order wasnt dismissed. Oh, and also not even canceling aid to israel.
@normie2716 thank you i feel the same way, I don't agree with the way he says things but it is those very attacks against him that got me to vote for him. He is doing exactly what he was elected to do.
@@zeroyuki92The FAA is the primary regulator of Boeing. It’s rare for EASA to go against it.
Your concerns are 100% valid and the regulators should take action before there is a catastrophe. I am not a pilot, i am involved in fire safety which obviously includes toxic smoke particularly in a confined space such as an aircraft cockpit. I find your videos very informative as i am a great fan of aviation.
When you ask people to operate a sophisticated piece of machinery, don't keep secrets from them. This message needs to cut across industries, not just aerospace.
Great work. I'm glad you reached out to the FAA.
Addicted to your videos...😍
Thanks for watching! 🩷
Awesome proactive work. Thank you for doing this!
It’s outrageous Peta. As a 737 pilot myself is like they have learnt nothing at all. The FAA must be being leaned on by someone either the government or Boeing. There is no reason whatsoever why they wouldn’t do something about this and try preventative measures. Disgusting. Disgraceful. The fact this has been leaked shows there is corruption and a cover up taking place. Best of luck with it hopefully something will be done. I’m in shock. Thanks for the information.
Follow the cash….this sort of lax regulation generally has money at the root.
there's some engineer somewhere concerned about all sorts of potential issues that probably are being shrugged off as annoying, there's a document called the PFMEA (Process Failure Mode and Effects Analysis) that probably should be shared publicly.
the issue is that it isn't taken seriously by executives (it's a standard requirement in industry but I don't even know if it's a legal requirement) if it was a public document (at least when accidents occur) then it may be taken more seriously.
I have seen no discussion about that after mcas
