I can't see anyone doing anything for a 2 yr old airframe.

I have seen several of these at our field with larger motors and not seen something like this happen. It would be hard to say exactly what happened. A hard landing or bouncing ( as they sometimes do) could have broken some wood overtime and was missed..

Sorry for your loss.. always hate tos ee that happen.. although with some patience and some long nights it looks like its repairable.. its a fairly clean break. I must say a plane like this is not really designed to be flown at full throttle in level flight.
