Sounds like he ground looped it and is blaming the failure of a part. He's just not saying which happened first, yet we have a pretty good idea.
Oops, darn it...

The FAA did mention Tundra Tires were installed. Got to be some reason for that on pavement.

As I recall the FAA stated the left gear fail under the plane as from inward forces.
I see this being the pilot was just not ready for the plane with the complication being he had a long emotional day with taking delivery followed with flight time and lessons/checkout.
When I first read this I did not see mention of wind conditions which have been wreaking havoc around the country for months now. I may need to go back and see if the initial report has been updated.

Ahah! A friend tells me that during an IA renewal seminar at the NW Aviation Show in February,
FAA's main speaker said there will be NO MORE FIELD APPROVALS FOR TUNDRA TIRES!!!
I knew they had a good reason!! :roll:

If it wasn't a crash, it for sure wasn't a successful landing.
A better outcome than would be expected though, considering the circumstances.
A guy I knew, a pretty accomplished pilot IMHO, had something similar happen, a number of years ago.
He was flying into Boeing Field in Seattle early one morning to go to work,
and somehow ended up dangling from powerlines near the airport by one MLG wheel.
His rescue by the fire department was covered on live TV.
Took him a while to live that one down.

How about stopping in a pond on a grey day when the flying has been great. Then after an hour or so taking off only to find yourself in the clouds as you cross the departure end of the pond with no clues that the ceiling had come down! Then in order to get to the nearest airport because the pond was no longer visible you had to fly in the clouds at 100 feet while following the roads looking straight down through holes. For about a total of 8 miles to get to the airport. Follow this road, cross the RR track take the next left, turn left at the traffic light, another mile then another left. There's the cranberry bog, gear down, reduce power keep the gear out of the tree tops. There's the runway close throttle, taxi to the hangar and call it a day.If we’s all honest, In certain conditions We’d all cop to take any landing to get on the ground!
Is that what you are talking about flyrite? This is a true story.

Pete,
That brought back unpleasant memories of a similar incident where an ATC person tried to “help” me out.
Called that night and said thanks but don’t need that kind of “help”.

That was essentially my 100 hr mistake, back in 1983-ish. Never looked up before departing the farm strip for work that day. Took a bit but made it back to the same strip, and learned from it.

Sounds like AOA mfgs are having issues. Boeing....Cirrus...
FAA Grounds Cirrus SF50 Jet over AoA Vane Issue
The FAA on Thursday issued an emergency Airworthiness Directive (AD) on the Cirrus SF50 Vision Jet, grounding the more than 110 in-service single-engine jets for immediate replacement of the aircraft’s angle of attack (AoA) vane. According to the emergency AD, Cirrus reported “the aircraft's stall warning and protection system (SWPS) or Electronic Stability & Protection (ESP) System engag[ed] when not appropriate” in three incidents since November 2018, leading to a stall warning crew alert system (CAS) message and activation of the stick shaker and/or stick pusher despite the aircraft maintaining sufficient airspeed and AoA for normal flight.
Further, the FAA said unintended activation of the SF50’s stall protection systems could result in excessive nose-down attitude and difficulty in maintaining control of the aircraft. The emergency AD came two days after Cirrus Aircraft issued a mandatory Service Bulletin (MSB) requiring immediate AoA vane replacement with a modified part from vane manufacturer Aerosonic after originally installed components were found with improper torquing and retention of two set screws mounting the potentiometer shaft to the AoA vane shaft.
While the Cirrus MSB mandated that SF50 operators have the replacement AoA vanes installed within the next five flight hours, the emergency AD “requires such replacement before further flight,” although operators are able to obtain a special flight permit to a location where the replacement can be performed.

I saw similar issues on several models of Falcon jets, always after de-icing. The vanes would get “sticky” from the fluid and cause some issues. The airspeed tapes displayed a yellow ribbon when approaching a high angle of attack, which would trigger a “stall” audio warning accompanied by either automatic outboard slat extension, or if the slats were out, automatic inboard slat retraction. It took both vanes indicating a stall to trigger the stick shaker. Gets your attention when it happens at rotation.

This certified one did: https://en.wikipedia.org/wiki/Aerocar Not sure it was the exact same one but certainly the same principle.

For reasons not clear to him the airplane departed the runway, shock broke and then the gear folded sideways under the airplane. Hmmm sounds like a ground loop and the shock failed when the gear folded under the airplane

trees are your friends, just big springs(or so i was taught)... don't go into lawn dart mode trying to avoid them, just land in them... know quite a few that walked away, once they figured out how to get down out of the tree....
and I've watch 6 people die in 2 crashes trying to avoid hitting the tress is last 7 or 8 years.... (lawn dart mode/stall)

I have family on my wife’s side that survived without a scratch after soloing on his first ever flight in a GA airplane. I think he lost his eyeglasses and that was it.
This happened after the PIC tried to hand-prop with no chocks and not enough instruction for the brake holder (my kin).
As the story goes, he figured out that pushing forward made the plane go down and he “landed” in the tops of some good South Alabama pines. Crawled down and walked home.
One of my changes of thought over recent years, I am going to have a hundred foot climbing rope tied off to structure under my seat in the plane I am building. The rope maybe knotted or such.
Now a question, did he stall that into the tree or fly it in?

100 feet of Spectra, or other small diameter para-cord type of line in your flight vest with a carabiner may be a better option. Might need to secure it to a tree branch over the pilot seat.
Good suggestion, I have been using AmSteel cord lately which I find impressive material, I expect it may be similar to Spectra. Need to pack a few devices to allow repelling since my hands can not grip those small diameter cords. Not sure anyone can for long.
I think the odds of ending up in this predicament are very slim,
chances of being uninjured and capable of safely respelling even slimmer.
We are blessed to live in a country with an exceptional SAR network.
they are funded and supported to provide aid in situations like this.
Might need to swallow ones pride to enguage their services but that’s what their there for.
Ones focus should be on first, reliable means to summon help, second a means to remain alive till help arrives.
Im all about self rescue, but not if there’s a chance of making matters worse and putting others further at risk.
