- This animation explores a number of aspects of the midair collision, which occurred on May 13, 2019 about 1221 Alaska Daylight Time. The accident involved a float-equipped de Havilland DHC-2 (Beaver) airplane, N952DB, and a float-equipped de Havilland DHC-3 (Otter) airplane, N959PA, which collided in midair about 8 miles northeast of Ketchikan, Alaska.
The sequence of events was reconstructed based on information extracted from Automatic Dependent Surveillance - Broadcast (ADS-B) tracking data provided by Federal Aviation Administration (FAA), aircraft performance data, weather data, and data from the manufacturers of the equipment and systems on board the aircraft that related to ADS-B.
Map views were constructed with Google Earth backgrounds. Three dimensional animations were developed in Microsoft Flight Simulator.

The photograph right before impact is chilling. RIP.
Yeah, it's like the animation comes to life in the worst possible way
Especially because it was taken by passenger on the disintegrated Beaver.
I agree...it’s a disturbing image for sure.
I wish that passenger had the presence of mind to tell pilot to dive.
@@stopthephilosophicalzombie9017 would of been too late. "HUH?" would of been ensued by the collision
I went on a sight seeing excursion in that exact Beaver a few years before this happened. The company was named Mountain Air and the pilot’s name was Randy I believe, he let me sit up in the co-pilots seat as I was a student pilot at the time and had always dreamed of flying in a DeHavilland Beaver. Super nice and down to earth guy, he put his life savings into buying that airplane and starting that business. My heart sank when I learned that he had gone down with his airplane. He passed on doing what he loved.
Don't mind me, just a weirdo that likes to watch accident analysis videos like this... I do hope that the recommendations made here are listened to
USCSB are great too
@@you900001 yeah they're the first ones I found with videos of this type
As a pilot in training here in Alaska, I find this sad, sobering, and humbling. Excellent learning lesson.
1) Brief your passengers to alert you to proximate traffic.
2) Do not disable equipment or components of safety equipment such as TAWS, TIS, GPWS, etc.
3) Understand and mitigate visibility limitations.
4) Review, know, and practice collision avoidance techniques
Common theme: a chain of events, following the “Swiss cheese effect,” all with preventable actions, lead to these crashes. It’s never any one issue or factor. This is why redundancy and vigilance are so important in aviation. Sad story here.
something else to think about, somebody died because the pilot didn't move his head like 1 inch in either direction. Pretty crazy.
Flew once in a Beaver with Talkeetna Air Taxi around Denali with a glacier landing years ago. It was very beautiful trip, but I noticed other planes in the fairly crowed space. I remember thinking while taking many photos that I would be on the look out for other planes! Seeing the photo taken by a passenger makes me sad to think the only eyes on each plane that may have seen what was about to happen LIKELY failed (I have no way to know) to alert their pilot. We were wired up with headsets so that we could speak and hear each other as well as the pilot. Air tourism in Alaska has a good record of safety.
Everyone at this point has already come to realize that see-and-avoid is a joke. Yes, students are taught to move head to avoid blind spot, but the only time people are doing it is on "traffic advisory" or joining pattern.
Lessons learned: TICAS is way better than ADS-B In, and turn ADS-B traffic alert on in your favorite EFB. You'll likely be near the airport, looking at the field, the instruments or charts, not those beautiful arrows on your "enroute view". Only after watching this video did I realize that I used ADS-B In only for weather (aircraft has TIS though).
Pilots, do your fellows a favor and turn on altitude reporting. And FAA should consider ADS-B out in Class G. UK CAA has even allowed portable ADS-B out for certain operations.
I move my head driving a friggin truck on the ground to avoid blindspot, you guys can move your head in a plane where the consequences are even higher
My second favorite US government funded UA-cam channel
What is #1, USCSB?
@@scose Yes sir, glad I'm not the only one.
It's been so long for a USCSB video. Which is a good thing... but...
Very informative. Hopefully this tragedy will inform pilots and help them to avoid similar accidents in the future
really curious why the Otter didn't have the piece of equipment to broadcast height in pressure units turned on.
Good reminder for me to figure out how to get the Foreflight traffic alerts into my headset rather than just on the screen.
BUT, if one or both pilots were looking at their "traffic screens", they would have still seen the converging traffic, correct?
It should be a regulation of the FAA to make all commercial and private aircraft to have all the bells and whistles activated while in flight ✈️ and especially if they are carrying passengers. SMDH😒😔
Is that FSX of FS2020 ?
FSX
Man, what a heartbreaking and avoidable accident! That picture was haunting...
Sadly, this can serve as a good lesson in many different areas. Complacency and operating any kind of machinery.... not acceptable. Common, but not acceptable.
This is why 'flying cars for everyone' is a horrific idea! people struggle with regular cars..... they, likely, don't have what it takes to be a pilot (that includes me. I'm not a pilot and don't think I have the mental dexterity, at this age, to have the awareness required to fly in a safe manner. maybe with years of training...maybe, I could get there). 🤷♂️
This will be in Season 24!
Why doesn’t ADS-B include GPS altitude in the ADS-B transmission data when no suitable barometric data is available?
Actually, I think GPS altitude data should be standard in an ADS-B, this would limit the errors cause by pilots that are not on the same altimeter setting. When looking at an ADS-B in display, all aircraft are shown with GPS altitude, this gives the pilot one standard frame of reference for the altitude of their aircraft vs the altitude of another.
The ADS-B transmitted altitude is the pressure altitude, not the indicated altitude. It's not affected by the altimeter setting. This is also how altitude is transmitted on altitude-reporting transponders. The receiving aircraft (or ATC in the transponder case) corrects the pressure altitude based on the altimeter setting. So even if the altimeter setting is incorrect, the difference in altitude (which is what really matters) is still correct.
Using GPS for altitude is not that good. GPS altitude isn't very accurate (the error can be as large as 400 feet), plus you need an extra satellite to determine the altitude, something that isn't always available.
Pressure-altitude reporting works as long as the static port isn't blocked or the system isn't disabled as the case in this accident.
Bro this wouldn’t have happened if the beaver descended and the otter climbed
Hang on while I snap a photo of this airplane that's about to hit us.
May those who perished rip, but….COULD NO ONE SEE THE BEAVER OR THE OTTER BEFOREHAND? Obviously they could cuz they took a photo of it just before contact….
I amost got into a crash because of my cars window post, they were in a blind spot
Pilot errors.
3:34 bruh
Season 24
Everyone knows Beavers and Otters are mortal enemies !
Window post is no excuse to not see other aircraft. I have moved my head to see areas obstructed by window posts.
Lesson: Do not flyvith idiot pilots too lazy to look for other aircraft.
