Analysis
The pilot reported that, he was going to conduct a high-speed taxi before taxing back to takeoff. During the high-speed taxi, about 2/3 of the way down the grass airstrip, the pilot reduced power and began to slow down. The asphalt overrun approached faster than he expected as the airplane over ran the grass airstrip onto the asphalt run-up area. The pilot overly applied the brakes which resulted in the airplane nosing over and coming to rest inverted. The outboard struts, rudder and engine mount were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
