He was cleared to FL230. You see 370 on the datablock because that was the requested cruise altitude. It's not the altitude dialed into the flight director or autopilot. We don't see what altitude is set within any equipment on the aircraft. The sector controlling the aircraft (ZSE05) has an upper limit of FL230, with ZSE16 controlling the airspace above FL230. The controller only assigns the aircraft to her upper limit, with the next controller issuing the climb to the final altitude. I'm a ZSE controller for over 35 years, now working in the regional office for quality control.

​@@dwaynejohnson6277 Reasonable question. The answer is that mechanical malfunction doesn't seem a good fit with the pattern of facts we have at the moment. We know the flight seemed a bit 'off' from early in the flight with that brief unexpected descent around 2117 UTC. We know that at one point he (maybe) dialled a completely incorrect altitude into the autopilot. We know the pilot was communicating on the radio, with apparently slurred speech, and he made no mention of mechanical issues or any problems at all. The almost symmetrical spiral descent seemed consistent with no active control inputs being applied. So the most likely explanation at this time is pilot incapacitation.

Really enjoy your channel!

Have done one instrument departure from Troutdale, it was a climbing left turn before heading south, due to high terrain immediately south and east of airport.

As a lifetime local, and with one whole hour of rotor instruction out of Troutdale, that flight plan makes sense, on good weather days the wind is commonly out of the east from the Columbia River Gorge. So a quick circle after take off to gain altitude makes sense before crossing the mountains.

Thanks for another excellent report, Juan. As a contractor I was required to go through the altitude chamber. I went to Brooks until they’d closed it down. As a private pilot learning my hypoxic symptoms was invaluable. One day we were on a test flight with us contractors and Air Force personnel. The guy next to me asked if I felt funny, and I said yes. A little tingly which is one of my symptoms we called the front end to check the pax (pressurization) and we had been at a cabin altitude of 18,000 ft so we all donned on our masks and carried on. Without the training that would have been unsettling. OH you are right about the color wheel. I couldn’t believe one puff of oxygen and the black and white wheel turned to brilliant colors. I think all general aviation pilots should go on a chamber ride. I talked to an FAA rep at Oshkosh about this experience and he said they could go to Oklahoma City and the FAA would give them a chamber ride free. Don’t know if that is still going on. But any of you GA pilots out there should definitely look into it. It is probably the best thing you could do to keep you safe. thanks again for another great video!

So very sad. Thanks for excellent report.

Juan, I looked at LiveATC and there was audio from 3RB's clearance readback, taxi, and takeoff on the ground frequency at TTD (tower frequency was having issues around T/O time for 3RB). He sounded older and slower on the radio than most, but not impaired. He did have radio issues just after take off when he was being released to departure frequency.

That was a great analysis and possible scenarios of this tragedy.

Very informative, thank you.

I'm a truck driver and I take my significant other along sometimes. About 8500 she starts to sound like this. No medical issues had her checked out immediately. The altitude doesn't bother me so I guess everyone is different.

It's always awful to hear that anybody has crashed. I was Marine Corps Aircrew for several years and training taught me a lot about aeromed and all that can go wrong and lead to a crash. Oddly enough, the altitude chamber picture used in your excellent presentation was the one I was trained in. (Marine C-130 Loadmasters used to go through Little Rock AFB for basic loadmaster training) In it I learned what my symptoms are, where I get symptomatic, and how to handle myself and crewmates when hypoxia rears its ugly head. Would be a shame if it were that "simple" of a problem, but I think others are correct that there was likely something else that was supplemental to or precipitous to hypoxia symptoms.

That’s soo sad! Already 2021 there are two accidents already. One is the Boeing 737 500 SLP182 The other is the Cessna citation N3RB

As usual very informative especially for the interested but none pilot. Thanks Juan 🇬🇧

If hypoxia is anything like carbon monoxide poisoning then I know how insidious it is. Years ago I was on a business trip as a passenger in a colleagues car. A familiar route, probably an hour each way, mostly on highways. On the return trip I suddenly noticed a familiar steel works. I though to myself "we are nearly home" followed by "how the hell did we get here?" the last thing i could remember was merging onto the highway 30 min before. I was feeling very strange so I asked the driver if he was OK - no response, but he was driving perfectly - steady in his lane and speed. I called more loudly and tapped him on the arm. No response. I knocked the car into neutral and gently pulled the handbrake on while nudging the steering towards emergency lane. That broke his trance and he stopped us safely. I don't know whether with hypoxia you recover quickly, but it took at least 30 mins before we could think clearly and I had the worst headache of my life for the rest of the day. It turned out that the exhaust manifold had cracked and the fumes were going into ventilation system.

I have a feeling this wasn’t hypoxia, the guy seems off from the start, and most people would not experience harsh symptoms of hypoxia that quickly at 13-14 thousand feet (for reference, the FAA doesn’t even post a useful time of consciousness at the altitude, and at 18000ft they state 20-30 minutes).

And not just the chamber ride but the whole course was outstanding! CAMI Summer '84.

Mahalo for the info. I was USN Aircrew. I went in the chamber with a few other classmates to learn our symptoms of hypoxia. I felt like I had a few drinks in about 1min. We played certain games while waiting for the effects,like patty cake, writing our SSN ect. I also saw grey on the color chart. 1 crew member actually got a nose bleed!

Thanks for the updated/amended post. Now it’s much better. One request: When you’re playing the audio and commenting/explaining (and, they are excellent explanations, thanks) please pause the file so you’re not talking over the recorded speech. Dan Gryder’s theory (Probable Cause) is startlingly different and my comment about his video: When the forensic psychological investigation is complete we may know what really happened. For example, is his life highly insured? And, what is his relationship to the other person on board? Were there mass covid-19 deaths at one or more of his businesses? Was he under investigation for that and more financial troubles?

Looking at Foreflight the airport, KTTD, has one Departure - Blue Lake 3. Departing Runway 7 climb via heading 055 degrees to 1,000' then turn left to 310 degrees or as vectored. The plate shows flying to Battleground VOR (BTG) then specific radials from the VOR, V520 (R-089) being the most likely IF they weren't vectored otherwise. The VOR is due north of Portland International (KPDX). There's also a Note: Rwy 7 requires a minimum climb gradient of 430' per NM to 4,000' (not that bad). Rwy 7 is 5,399' long. Field elevation is 39'. There is also a DIverse Vector Area Notice that's too long to reproduce here.

Thank you Sir.

That the passenger did not seemingly attempt to use the microphone, suggests he/she was incapacitated as well. This also raises a question about supply of supplemental oxygen. The pilot could not have been unaware that about 10 passenger masks would have dropped. That would explain why his climb was briefly stopped at 13,000. Supply valve was off or oxygen not serviced? I read where he had purchased the plane in October when it went through a prebuy inspection and service in Scottsdale and he had not flown it since November. Preflight inspection? Checklist?

Thank you. 🖖

Spot on..........

Excellent breakdown. Love the inclusion of VASAviation and Flightradar24, both of which I use constantly. I also immediately thought hypoxia, but as another comment mentioned, the pilot seemed off even prior to reaching the higher flight levels where hypoxia would (normally) start to affect him, although different people have different tolerances. Such a tragic incident, will be interesting to see the final NTSB report to help us understand what happened.

VAS is the man...thanks Juan your ok too

Thanks Juan. As an air traffic controller, I'm looking intently for anything that jumps out to me as perhaps something a controller might have been able to catch in time to perhaps make a difference. The controllers sensed some radio and perhaps navigation difficulties, but nothing that strikes me as sufficiently out of the ordinary as to merit particular concern until it was far too late. With hindsight, the pilot's voice wasn't fast and crisp, but we all hear lots of pilots a day who aren't fast and crisp on the frequency. I agree that he does not seem to have been on autopilot at the end, as no autopilot I know of would do multiple 360-degree turns without very specific and unusual pilot input to do so.

Listen to his respiration on-mic. Something not sounding right there....

I thought the controller did a get job. Saying that 370 was set in the altitude alerter based on the data block shows a lack of knowledge of the systems in airplanes.

I've used the Navy's version of the ROBD and I found it 200% better then the Chamber ride. The chamber was fun, but the ROBD is more scientific and provides a-lot of great feed back (O2 levels vs feelings). Thanks again for the videos!!

I assume that the "sine wave" variation in groundspeed at the end is an effect of an alternating headwind/tailwind in the descending spiral?

@@blancolirio the pilot was sluggishly speaking when he was at 14,000. Kinda low for being full on hypoxic even with NO cabin pressurization... Stroke, aneurism , thrombosis, heart event and medicine side effects are possible, followed by alcohol or recreational drugs. I doubt there was anything wrong with the aircraft.

It's in a moving air mass.
