The airplane’s collision with a submerged object during landing, which resulted in a nose-over.
NTSB analysis
The certified flight instructor (CFI) stated that the purpose of the flight was to practice glassy water landings in the float-equipped airplane. They overflew the practice area to check the condition of the river and the CFI stated that there were no obstacles or debris visible. Shortly after touchdown, both pilots reported hearing a loud bang and the airplane immediately nosed over. Both pilots exited the submerged airplane and sustained minor injuries. According to a Federal Aviation Administration inspector, the wreckage showed damage consistent with striking a submerged object. The airplane incurred substantial damage to its canopy, hull, and tail.
