At about 1700 Eastern time, the airplane was substantially damaged when it nosed over during landing. Visual conditions prevailed. The Certified Flight Instructor and Student pilot were uninjured. The CFI later stated that he was demonstrating a soft-field landing and the airplane was fast and floated down the runway. The pilot was unable to stop the airplane on the runway; it traveled off the end onto grass and nosed over. The CFI stated there was no malfunction of the airplane or its systems.
