I am not sure what you mean?
That this was either a line check or a line training sector is highly probable, but that does not in its self make it less safe, the rules that govern pilots under training are well established, they are not flights that are more risky. For most passengers the only way they would be aware of a lower experienced pilot at the helm, might be a firmer landing, but i still do that now and again!!
I have yet to see any pictures of what happened to the landing gear? i would have expected it to have been torn off as in the EMA/TNT event or punched through the wing as in the LHR/BA777 or ROME/RYANAIR event.
