Nosewheel ground loop?

CNN has a thumbnail that won’t resolve on my phone. Looks survivable. Tailwind landing perhaps?

Kind of looks like the most common crosswind landing error: neutralizing the controls after touchdown.

That usually means a lifted wing and dragging the other wing, and I don't see wing damage there.

Touching down too fast means that the wing's angle of attack is lower, so the whole airplane is more level when its nosewheel hits. This usually starts the airplane porpoising as the pilot, out of phase with the pitching, tries to control it. The porpoising gets worse until the nosegear fails.

Too many pilots still don't understand the relationship of airspeed to angle of attack, and this is the result.

 
Too fast no flair landing on nose wheel first could be a possibility
 
Not enough right aileron after the otherwise good crosswind touchdown, and/or the maximum crosswind component for the airplane was exceeded?
 
One of the Oshkosh landing compilations from (?) 2022 shows a Tri Pacer *almost* having this accident in a strong crosswind. Narrow track, short wheelbase, lots of surface area up high means it isn't as stable on its gear as most other trigear aircraft. It is more likely to be tipped in a crosswind, particularly under braking... The nickname "flying milkstool" was bestowed for a reason.

Way too fast, evidenced by all three wheels touching down at the same time. Too fast even for a crosswind.

Have a good bit of Tri-Pacer time and never had trouble with crosswinds...agree on the excess speed.
 
Wheelbarrow landing. I did this on my very first flight after getting my license. I was way too high in a 172 and came in too fast. Lifted the right main off the ground, but caught it in time.
 
Tend to agree with the excess speed. Looking at the video closely it looks like the pilot did apply Right Aileron as the right wing started to come up. I also seem to see left Rudder. Which is good since the Tri-pacer has a Aileron-Rudder interconnect meaning the pilot had to overpower the interconnect to get left rudder in with the Right Aileron. It also has a direct connection to the Nose wheel meaning that left Rudder also mean left nose wheel Steering Might just be the control input where to little to late. Biggest issue I see looking at the wind sock in the background is it looks like a quartering tailwind to me. Which would mean things happened fast and the aileron Rudder would be pretty ineffective as it slowed down. Would be interesting to know what the reported winds were if available.

Caught on camera: Dramatic video of small plane crashing during windy landing at Sunriver Airport; pilot unhurt - KTVZ

The pilot of a nearly 70-year-old small plane was uninjured when the plane tipped over and crashed on its nose during a wind-challenged landing at Sunriver Airport Saturday afternoon.

Looks like almost direct crosswind decided to pick up about the time he landed crashed (~2030Z).

An overreaction to a brief cross wind from the left will cause that to happen. The nosewheel contact with the pavement turns the plane to the right and causes the left wing to drop. The CG "rolls over the nosewheel and left main" and causes the left wing low, tail high, nosewheel overload and prop strike, i.e. "wheelbarrowing" as mentioned above. It's the rare groundloop in a tricycle gear aircraft.
 
I love how the newscaster emphasizes "70 YEAR OLD PLANE"!!!...like it matters.
