## Analysis

The pilot reported that the airplane "bounced twice" as he was attempting to land on the asphalt runway. He decided to execute a go-around and applied full engine power. However, the airplane "did not lift out of ground effect" and a wheel "caught the grass" causing a ground loop. The pilot noted that the accident might have been prevented by leveling off to allow the airspeed to increase before attempting to climb. He reported a variable wind at 10 knots with gusts to 15 knots. The airplane sustained substantial damage to the fuselage and left wing.
