Analysis
The airplane departed modesto airport (mod), modesto, California, on a v.f.r. pleasure flight to Half Moon Bay airport (haf), Half Moon Bay, CA. The flt to haf was uneventful. The plt negotiated a traffic pattern to runway 30. During the landing roll-out the plt reported the airplane's left wing began to rise and he immediately added power and left aileron, but to no avail. The airplane's right wing contacted the ground and the airplane ground looped to the right. The pilot also stated that the surface winds were calm and the flight controls operated normally.
