The pilot was practicing touch-and-go takeoffs and landings at the airport in Camarillo, California.
During the second landing he failed to maintain directional control.
The Piper PA-18 subsequently departed the side of the runway, and ground looped, which resulted in substantial damage to the left wing and left lift strut.
The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operations.
Probable cause: The pilot’s failure to maintain directional control during the landing roll.
