A hard landing isn't supposed to break a commercial airliner apart right?

Notice there is a subtle difference between a "hard landing" and stalling at runway threshold and slamming the ground.

All aircraft are certified to a touchdown vertical speed and usually you can get away with a really hard, firm bash which is sometimes preferred and recommended, if runway is short and wet for example. Trying to "float" and do a "softish" landing can get you off the runway end (happens a lot more than you think or hear about).

I have no clue about "Xi'an Aircraft" but I wouldn't blame the manufacturer (yet).

It depends on how hard the landing was. A "hard landing" shouldn't break the aircraft apart, however, the airframes have structural limitations. I've seen photos of a Lufthansa B747 broken aft of the wings because the jacks under the wings depressurized.

American made can break if the landing is heavy enough, link 1.

But to answer the question, yes a heavy landing can cause considerable damage.

I expect the incident you're talking about is in link 2 which has all the details.

If it is really, really hard (rare), yes, they can break.

A chinese aircraft is much more likely to break though. Same thing for everything else made in china (motorcycles for example).

'Hard landing" covers a lot of territory, anywhere from an unusually hard thump

to just short of a crash.

That said, commercial aircraft are not supposed to make hard landings.

I would never fly or fly in an aircraft made by chinese

Land anything hard enough and it will break.

I think the operative words here are "Chinese made"
