Probable cause

The pilot's failure to maintain directional control during the landing roll.

NTSB narrative

The pilot reported that he had not flown for several years and had just received training from a certified flight instructor. During his first solo flight since the training, he was conducting touch-and-go takeoffs and landings. On the fourth landing, the airplane veered off the runway to the left side and ground-looped. After departing the runway, the airplane impacted a metal obstruction with the left landing gear, substantially damaging the tubular fuselage structure.
