Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the aerial application airplane surveyed the field at a higher altitude prior to spraying. He determined that spraying north and south, while flying below high-tension lines, would require the least amount of maneuvering in the heavy airplane. The pilot flew the first pass uneventfully; however, during the second pass, the airplane’s rudder contacted a powerline. The rudder separated and the airplane landed sideways in the field, resulting in substantial damage to the wings and fuselage. The pilot stated that there were no preimpact mechanical malfunctions or failures of the airplane that would have precluded normal operation.
