Analysis

The pilot stated that he departed to apply fertilizer to a timber field 11 miles southwest of the departure point. He noticed that his fuel was low and turned on the fuel boost pump. He continued to finish his fertilizer load. The pilot stated that during the return to the landing zone, "the airplane ran out fuel and the engine stopped". He then made a forced landing in a field and the airplane collided with a row of trees next to a creek. The pilot turned off all electrical switches and exited the airplane. The pilot was uninjured, and did not report any mechanical or flight control anomalies prior to the accident. Examination of the airplane by an FAA inspector revealed that both fuel tanks were empty. The wings and fuselage were also buckled.
