Analysis

During day agriculture operations, the pilot lost outside visual references due to dense smoke coming from the chemical hopper. The pilot elected to execute a forced landing on the adjacent runway. During the approach the airplane struck a set of electrical transmission wires. Following the landing the hopper erupted into fire, so the pilot abruptly pulled the airplane off the runway. During the abrupt ground maneuver, the right main landing gear broke off. Following the loss of the landing gear, the fuel cell ruptured and ignited, resulting in the airplane being consumed by fire.
