Narrative:

On second approach for landing; after both main wheels touched down; the aircraft moved diagonally from the center of the runway to the left edge; applied right rudder to correct the move left; reorienting the direction of the aircraft back toward the center of the runway; but the left wing dipped and the aircraft felt as if the landing gear wanted to go right; while the mass of the aircraft was going to keep going left; in a twisting motion. I initiated a go around. I did not have sufficient airspeed to correct the left wing dip with ailerons. Before the aircraft achieved sufficient airspeed to lift off directional control was lost and the aircraft ground looped coming to rest on the nose; right main gear and right wing. Winds at the time were reported as 040 @ 10. Pilot and non-rated passenger were both able to escape the aircraft without injury.
