Narrative:The 9,901-hour commercial pilot lost control of the tail wheel-equipped airplane while performing aerial application. According to the pilot, the engine produced an "explosion" like noise prior to a total loss of engine power. The pilot was then forced to land the airplane in a cotton and soybean field. Upon landing, the airplane sustained damage to the propeller blades, both main landing gears, both wings, the fuselage, and the vertical stabilizer. The pilot reported that at the time of the mishap the airplanes' altitude was approximately be 5 to 10 feet above ground level, resulting in a lack of suitable terrain for forced landing. Teardown and examination of the engine revealed the failure was initiated by a compressor turbine guide vane ring crack at a weld repair that released material into the compressor turbine blades.
Probable Cause: The total loss of engine power due to a power turbine failure. Contributing to the accident were the lack of suitable terrain available to pilot for the forced landing and the low altitude.
