AT ABOUT 1245 EST, THE PLT TOOK OFF ON HIS SECOND FLT OF THE DAY AND FLEW IN THE LOCAL AREA ABOUT 30 MINUTES. UPON RETURNING TO ORANGE COUNTY ARPT, THE PLT OBSERVED THE TETRAHEDRON DURING THE LEFT DOWNWIND LEG FOR RWY 25, AND NOTED THAT THE WIND HAD CHANGED DIRECTION ABOUT 90 DEGREES. ADDITIONALLY, THE WIND SOCK WAS ALMOST STRAIGHT OUT, INDICATING ANINCREASED VELOCITY. THE PLT EXECUTED A TOUCH-AND-GO LANDING, AND ON THE SECOND APPROACH, ACCORDING TO THE PLT, HE WAS UNABLE TO MAINTAIN RWY ALIGNMENT DUE TO LOW LEVEL WIND TURBULENCE, THEREFORE A GO-AROUND WAS PERFORMED. FOLLOWING THE THIRD APPROACH AND TOUCHDOWN, THE ACFT VEERED TO THE LEFT AND DEPARTED RWY 25 ABOUT 800 FEET FROM THE APPROACH END. THE ACFT TRAVELLED ABOUT 400 FEET BEFORE COLLIDING WITH A DRAINAGE DITCH. THE ACFT THEN FLIPPED OVER AND CAME TO REST INVERTED.
