## Analysis

The pilot reported that the landing was "hard and the plane bounced, I tried to get it under control, but the next time it came down it also hit hard." He reported that he tried to execute a go-around but the airplane for a third time, "came down again and ground looped." The airplane departed the runway to the left, the right main landing gear collapsed, and the right wing impacted terrain. A postflight inspection revealed substantial damage to the right wing. The pilot also stated, "I should have had more training in this airplane, and I should not have landed at an airport with such a high density altitude." The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
