Similar thing happened to United in 2019. Even ended up on the left cowling

Thank you for sharing I’m on the A320 and never flown a Boeing product. Very hard to judge actual sink rate from the video but from my point of view it looks like a hard landing but nothing that I haven’t seen on the line where the plane was fine afterwards except for some egos.

A Trunnion failure is rarely critical and normally does not cause a complete gear collapse. The landing did not look that hard in the video buts that could be deceptive. The answer to that question however I am sure has already been determined by the FDR. A Trunnion failure also does not normally drive the strut up through the wing. It might be months before the real cause is released. The recent Delta evacuation in Atlanta is rumored to be a hard landing but nothing is out yet.

However, I'm not sure they'd give those planes 500 hours. What if a crew tried to do a go-around? With the gear stuck down, part of the upper wing wrecked, and good chance of a dead or degraded motor... all on the same side. What's the Vmc for that?
