After two approaches that resulted in go-arounds, the pilot touched down on the third landing attempt. The pilot reported that he touched down too fast and bounced three times in a "classic porpoise." On the third bounce he attempted a go-around but had insufficient runway remaining. Subsequently, the airplane overran the runway and the main landing gear and nose wheel dug into soft mud. The airplane sustained substantial damage to both wings and fuselage.
The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
