Analysis

According to the flagman for the aerial applicator the pilot had completed his first swath run and initially pulled up and turned right. He then reversed his turn to the left in order to align the airplane for the second pass. The flagman observed the airplane to be still in the left turn nearing the swath run heading when the right wing seemed to get too high. He stated 'his right wing just seemed to keep coming over till he was 3/4 cocked and going straight down to the ground.' After contacting wires the airplane collided with the ground in a residential street and was involved in an intense post crash fire.
