Narrative:
Failure to control the aircraft during landing is the root cause of the accident.weather conditions were light and variable from 140 -> 200 @ 4kts. As usual in the area of ZZZ there were conventional turbulence from the tree-line west of the airport and cliff faces to the south and east. 10+ miles of visibility clouds were no factor.due to the turbulence; I carried additional speed throughout the approach. The target for a three point landing is 55mph and I was flying a stabilized but bumpy approach at 60mph.approximately 10 feet off the ground mid flare; the aircraft descended through a pocket of air. I corrected by increasing the aoa mitigating the rate of decent and landed in a 3 point attitude. Observers from the ground say I rolled about 100 feet on the ground before becoming airborne again. The wing exceeded the critical angle of attack and stalled the drag of the stalled wing pulled the aircraft with a yawing motion while dropping back onto the runway. I input full rudder control inverse of the yaw rotation and attempted pulsing the brakes while leaving the ailerons neutral but it was too little too late. I departed the centerline and spun [approximately] 270 degrees off to the right side of the runway; the typical ground loop. The aircraft wing appears to have touched the ground creating a scuff on the paint smaller than the size of a dime. Accident chain: - failed to maintain proper speed on approach leading to excessive energy during flare and landing. - Failed to correct the attitude of the aircraft after becoming airborne again. - Failed to add power to gain more control authority. To prevent this from occurring again. I am going to practice with a CFI my landing patterns to identify if I have picked up any bad habits. I am going to go-around if my approach is not stable (explicitly; including proper speeds during the approach and before flare). If the aircraft is near flying speed and starts to come unglued from the runway I should consider adding power to give more control authority to the rudder.
