What Your Senators Need to Know About and Act On! REVEALED: This System KILLS in 39 Seconds and Nothing is Being DONE!

Competent Investigator making Safety Recommendations REMOVED from his position. FAA ignores these safety issues! Boeings Failures to make their planes safe and FAA Collusion to keep us all flying on Death Flights makes me want to never fly again. Fly at your own Risk! No wonder we are seeing all these dangerous incidents. Look at some of these comments:
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!
My Senator, Maria Cantwell, is the Ranking Minority member on the Transportation committee. I just sent her an email with a link to this video, and the Seattle Times article, asking her to look into this. Thanks for putting out this video,

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 am one of your long time follower . I am an ED doctor and I have a bacground in clinical toxicology and aviation medicine. Your video highlights an even darker, poorly understood, and largely undocumented concern regarding bleed air contamination, known as Aerotoxic Syndrome. Organophosphates (from engine oil additives such as tricresyl phosphate (TCP)), thousands of volatile organic compounds (VOCs), carbon monoxide, hydraulic fluids, and de-icing agents can potentially infiltrate the cabin air through fume events—not only during dramatic incidents like a bird strike, but also during routine operations. Some pilots have voiced concerns about low-grade exposure due to seal degradation or malfunction, allowing engine oil or hydraulic fluids to leak into the air supply. The long-term health effects of such chronic exposure on crew members and passengers remain largely unknown. Naturally, this is a non-issue for airlines, as diagnosing an engine for this type of problem requires a complete engine teardown, making it both time-consuming and costly. Although the issue is often downplayed, some scientific literature exists on the subject. Studies such as those by Michaelis et al. (2017) and Howard et al. (2018) have documented cases of neurological and respiratory impairments among flight crews, linking them to contaminated cabin air exposure. To the best of my knowledge, no publicly available data exists on bleed air quality under standard operating conditions or during fume events. I would be very interested to hear your thoughts on this issue.

MAX Captain. Probably the most impactful video I’ve ever seen. Plan to write an FSAP, IOR and contact my fleet and ask for transparency. Left pack off or APU pressurizing is simple versus catastrophic left engine failure.

I shared that video with the ALPA OSH at Air Canada since I’m a pilot there and apparently I wasn’t the only concerned pilot. The union and the company are supposed to meet shortly and the pilots advised. Thanks for that great video, truly making a difference!

Many years ago a friend of mine who was a captain with Air Uk and KLM died of a Brian tumour. He had been subjected to fume events while flying BAE 146 aircraft. After his death it was discovered that other pilots had suffered health issues from inhaling the toxic fumes. It is something the manufacturers should really have dealt with

Petter, I believe this is the most important video that you have produced. The culture of not informing pilots of systems on the aircraft they fly is simply unacceptable. There is an increasing look at the FAA since the DC mid-air and the NTSB subsequent frustration with the FAA going public. Hopefully, your video will break the bank so to speak and drive FAA accountability.

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.

Thank you for making this video. The lack of ownership at the FAA is truly concerning.

I work as an aircraft technician and we use a bleed air cart to supply cooling air when we’re performing operational checkouts on the aircraft. Sometimes, if our new guys follow the wrong procedures, or latch the valves in the incorrect order, we can have fumes enter the crew station from the bleed air carts. It happens probably once or twice a year and the first time it happens everyone freaks out, but all of us veterans know what they did wrong and quickly correct it. As someone who’s been doing it for 12 years now, I couldn’t tell you how many times I’ve sat in a crew station during these fume events and just pressed on with the checkouts to get to the next job, often trying to calm down the new guys and letting them know how/why it happened and how they can make sure it doesn’t happen again. However, I never once stopped to think about what I was breathing in and how that could affect my health. We knew it was exhaust fumes, but its rarely enough to seriously affect visibility and it smells kind of like the type of exhaust smell you get when you’re mowing the grass or using a chainsaw, nothing that would immediately cause alarm to someone who regularly uses small gas engines. I think I’ll probably be shutting down and exiting the aircraft the next time this happens.

The email response that there are ‘miscoceptions’ in your question and then no follow up phone call tells you all you need to know. They know they made a mistake in their assessment and are trying to deflect.

Petter, after watching you for years its clear that you are level-headed and never sensationalize. In fact you go out of your way to reassure your viewers of the safety of air travel. The fact that you are this concerned tells me that we need to take this very seriously.

Retired 737 captain: Seeing your video and reading the comments, there seems to be little doubt about the potential danger of releasing oil fumes into the air conditioning system. Both cases happened at low level with autopilot disengaged. Adding a smoke problem ( which was in itself a hated simulator exercise) at such a moment to any other problem is evidently asking for catastrophe. As mentioned in other comments it would seem logic to rethink or stop using bleed air for air conditioning. In the name of all those whose lives you are trying to save: thank you for this excellent and exceptional video!

Can I as a passenger just say that, after reading through the comments and seeing so many responses from people working in aviation who said they will forward this to collegues, I already feel much safer knowing this problem is actively being shared in the community. Fantastic job with this video Petter and team!

I’m a B737 captain having experienced a hydraulic smoke event on the ground right after startup of the left engine. Smoke filled the cockpit so quick you can’t imagine. I shut the engines down immediately and we both pulled the windows open, I couldn’t see my copilot. Shutting down the engine stopped the smoke from becoming more severe and after most smoke went out of the windows I got out of my seat to see what was happening in the cabin behind the cockpit door, I saw a whole cabin of surprised pax watching me coming out of the smoke filled cockpit, no dense smoke was in the cabin, handling was really fast in getting stairs at the airplane and everybody could evacuate via the stairs while the fire brigade checked if there where fire hotspots in the engine causing the smoke with heat detectors, my copilot and I where checked in an ambulance for the smoke inhalation. This happened on the ground at the parking spot. Still don’t know what exactly caused the smoke, I was told a malfunction in the hydraulic pressure system, the airplane was grounded for a long time (months, after being flown back empty and unpressurized to the homebase after 2 weeks) as all air systems had to be replaced. This was on a B737-700 about 10 years ago now.

I have been watching your video since 2015. I worked for an US airline for 20 years retired now. This is in no doubt one of the best video you ever made and should be seen by all flying crews in the industry. It is baffling that the FAA has issued stronger directives to all airlines. Thanks again for your unbiased presentation and your continual work for the industry safety and safety of flying crews worldwide. Thank you.
