What happened
During a scheduled crop spraying operation near Townsend, Montana, an agricultural aircraft experienced a significant mechanical failure. While operating at a low altitude, the left engine suffered a loss of power and subsequently became detached from the aircraft.
In response to the emergency, the crew attempted to perform an unplanned landing. However, the aircraft was unable to complete the maneuver successfully and crashed at the scene. The impact resulted in the total loss of the airframe. There were two occupants on board during the incident, both of whom sustained slight injuries.
Findings
Investigations into the accident determined that the primary factor was a mechanical failure involving the left engine. The engine lost power and physically separated from its mountings while the aircraft was in flight.
