Analysis

The acft went off the departure end of the rwy and collided with a ditch after which it erupted in flames. The temperature was 87 degrees with light wind. The density alt was computed to be 5000 ft. the plt had stated to the operator that he thought it was too hot to spray. The boss asked him to try anyway. Some other plts had trouble climbing out of ground effect and reportedly tried to radio a warning. The acc plt during takeoff tried to jettison his load but the acft failed to clear a ditch off the end of the rwy. The plt had filled his fuel tanks to the full mark but the chemical hopper was only about 2/3 full.
