ERA24FA304 · Air Tractor AT802 A

The agricultural application airplane was loaded with agriculture chemicals and fueled at the owner’s operating base about 25 nautical miles away the accident site. Flight track data showed that upon arrival at the field the pilot began his aerial application to the western section of the field, from south to north. The pilot made a subsequent approach from north to south to spray the east side of the field, then made a right turn for another south to north pass on the west side. After the pass, the pilot initiated a climbing right turn, during which he leveled the wings and continued east-southeast in a relatively straight heading but descending. The airplane impacted mature corn and terrain in a slight right bank, but in a nearly flat attitude. The wings and fuselage impacted the ground in a nearly horizontal attitude with a forward speed estimated to be about 87 kts. The airplane skidded across the terrain, an asphalt road, impacted a ditch, then skidded across a bean field before coming to rest about 220 ft from the initial point of impact. Examination of the airframe, engine and components revealed no preimpact anomalies that would have prevented normal operation or airplane performance. Review of maintenance records did not reveal any systemic or repetitive safety of flight issues. The lack of any turbine, compressor blade, vane, or shroud rubbing damage along with the damage observed to each of the five of the propeller blades indicated the engine was likely at reduced power at the time of impact, but no other anomalies were observed. It could not be determined if the pilot reduced the engine power manually or if he became distracted and lost situational awareness during the climb and turn. Medical and toxicological findings did not suggest an incapacitating event. Based on all available evidence, the pilot, during low altitude maneuvering typical for aerial application flights, lost control of the airplane and impacted terrain for unknown reasons.
