Korean 773 Blows MLG on ldg with clip ...
Well, that Boeing is certainly not going anywhere for a while!
Yeah. A little bit wobbly but I’ve done far worse than that. Looks like some kind of failure in the right gear assembly, not necessarily related to the touchdown. Main gear steering problem, perhaps?
Must admit having looked at it a couple of times I’ve been thinking similar...
Sure there’s what looks like period of what looks like roll PIO and also what appears to be a fairly dramatic but brief reduction in pitch attitude at one point but it doesn’t look like the ROD was massive at touchdown and it doesn’t appear that the truck was thumled into the ground due to a high roll rate...but appearances can be deceptive so it will be interesting to see what “g” was recorded...wonder if we ever will?
Fullwings: just seen your comment about maingear steering - looking at the image of the gear I see what you mean...

Nicely understated! Wheels all wonky, etc. One wonders how much harder it'd have to have been for the gear to have collapsed. Sturdy things.
You can see a certain wobbliness in the approach, quite a lot of yaw to the right just before touchdown (I can't see right rudder being applied), lots of up-elevator just as its touching down, and a boot full of left rudder as the right hand gear gets mushed into the runway. I don't know if it's just the video compression hiding things or not, but the left rudder seems to be applied very suddenly. It looks like it was quite blustery - the grass is getting blown around a lot. Just a bad day at the office? ACMS pointed out that the touchdown itself didn't look very hard. I wonder if it was quite hard, and a lot sideways?

Assume there is a cycle life limit on the landing gear. Any more info about that? The landing itself looks not that bad and no tire did burst. The banana ist still straight so I doubt that this was a hig G landing.

Blocked wheels righthand...?
But visible part of tyres dont look that bad..
so would require flat spots on the opposite side...
Would not be enough for an axle overload like that...
Wobbly approach...
what if it had blocked wheels and touched down rh first?
Would have to look at that on a bigger screen than this mini ipad...

Since its a 300, can the actuator for the levered gear lock so all the weight remains on the rear as it settles down? It appears from the rear view picture that the rears are pointing toward the engine like the rears were taking a heavy side load as it touched down, but it also needed a heavy vertical load to camber them apart like that. Looks kind of like a friend's car when the shop dropped it off their lift.
I like the guy in the photo: “Hmmm, I’m pretty sure it’s not meant to do that...?"
An interesting failure mode. The (titanium?) shaft that forms part of the bogie appears to have split underneath and allowed the rear wheels to rotate upwards. I would be surprised if this isn’t some kind of defect as you’d expect the tyres to go before the undercarriage starts coming apart...

HD version shows it much better, a float, then a sudden pitch down on right landing gear. (note that on youtube, when in HD, under settings, you can have the video play at 0.25 speed)
Nailed it! (the landing that is) Right gear hits so hard that left gear comes off runway)
Now the rebound from the right hitting so hard

4 Reds! Unstable! Go Around!
You will note that the left bogie is almost flat, meaning it is on the ground...
