Doesn’t seem difficult - a hard landing is where you have a high rate of descent during the touchdown. Depending on the actual rate, and the subsequent forces exerted, that may or may not exceed the design limits and result in structural damage. A high rate of descent during the landing ‘phase’ can be arrested prior to touchdown or a missed approach carried out. The circumstances behind how and why the high rate of descent occurred might constitute a ‘serious incident’ and warrant an investigation - I’m guessing that’s what is happening here.
