Analysis

Aerial application passes were being made north to south with each pass being beneath cross country power lines in the middle of the field. One flagman was positioned at one end of the field with a second beneath the power lines. During the sixth pass, for unknown reasons, the flagman failed to move as the airplane approached. According to the pilot, 'due to the height of the wires and their close proximity, I was committed to pass under them.' He unsuccessfully attempted to pass beneath the wires and over the flagman. The left main gear struck the flagman and the airplane collided with a levee before control could be regained. An uneventful landing followed.
