Approach and Landing
The pilot elected to practice landings on a gravel road. During the first approach, he was high and elected to go around. On the second approach, a landing was made. The pilot reported that during touchdown, the airspeed was fast and the aircraft began to porpoise.
Go-Around and Impact
When it became obvious that there was insufficient room to complete the landing, a go-around was initiated. After lift-off, the aircraft's left stabilizer struck a fence post. Subsequently, the aircraft settled, the nosewheel struck an irrigation system, and the plane nosed over.
Environmental Conditions
The density altitude was about 4700 ft.
