The airplane impacted rising terrain while maneuvering on a public use animal control flight. The pilot said that he had turned and was heading south and had begun a shallow descent to maintain a constant altitude above down-sloping terrain. The pilot said, "As we continued to descend I noticed a slight rise in the terrain and determined that we had plenty of altitude to clear that rise and continued on with my southerly flight path and shallow descent. As we approached the slight rise in the terrain the pressure in the stick changed very quickly with a movement in the pitch axis only. The pressure came back immediately and then there was another pressure change in the stick that was a little more pronounced. This movement was identical to the other in that it was a pitch change only; there was no movement in the roll direction. After the second time the pitch change changed I made a remark to the gunner and the crash took place." Flight control continuity was confirmed. An examination of the airplane's systems revealed no anomalies.
Probable Cause: The pilot not maintaining clearance from the rising terrain. A factor contributing to the accident was the rising terrain.
