The pilot in the multi-engine airplane reported that, during the landing roll, shortly after touchdown, the airplane "floated up" into a right bank and then touched back down in a right bank. He added that he did not realized there was any damage until after he shutdown the airplane after parking.
Postaccident examination revealed propeller scars on the asphalt runway, damage to the right engine propeller, and substantial damage to the fuselage structure.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
