Analysis

According to the pilot, he departed Pineland with a load of chemicals, but could not locate the assigned field. He returned to the airport with his full load and was landing on runway 35. The pilot reported that when he 'attempted to stop the airplane by using Beta, the right brake failed and the engine torque pulled the airplane to the left into a ground loop.' During the ground loop, the right main gear folded under the fuselage and bent the right wing at the mid-point.
