The flight instructor of an amphibious float-equipped airplane reported that, he was demonstrating to the student pilot a water landing and step taxi from the back seat. While in the step taxi and preparing to takeoff, the student alerted the flight instructor to a channel hazard marker directly in front of the airplane. The flight instructor was unable to respond before the left wing and left side float collided with the marker about a second later. The left wing and left side float separated from the fuselage resulting in substantial damage. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The pilot of the tundra tire, and tailwheel-equipped airplane, reported that during the initial touchdown on the asphalt runway, the airplane bounced.

She attempted to correct by adding full left rudder and slight brake pressure, but the airplane continued to the right. She then applied more brake pressure and the airplane nosed over.

The airplane sustained substantial damage to the rudder and left-wing lift strut.
