The NTSB's narrative final · quoted from the NTSB record

According to the pilot, during the takeoff climb with full throttle, the agricultural airplane 'felt heavy and the airplane would not climb.' As the pilot turned the airplane to return to the airport, the airplane 'started to settle and he heard a squealing noise from the engine.' The pilot attempted to dump the load; however, the airplane touched down in a field, impacted a ditch, and nosed over coming to rest inverted. The operator determined that the engine supercharger had failed.
