Analysis
The pilot of a float-equipped airplane reported that immediately after touch down, the float plane encountered a boat wake, veered sharply to the left, water-looped, and became submerged inverted. The float plane sustained substantial damage to the left wing. According to the pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The pilot reported that the wake that his float plane encountered which precipitated the water-loop may have been generated by a boat that is used by a local ski school.
