Read the full NTSB narrative

The 18,000-hour pilot completed his fifth aerial application pass and initiated a right turn to return to the field to start his sixth pass, when the airplane impacted terrain. A witness located north of the accident site reported to have observed the airplane in a right turn as it impacted terrain, right wing first followed by the engine. An engine examination, revealed the prime mover exhibited impact damage. The accessory mounting studs were pulled out of the accessory case. The air inlet portion of the gear case assembly was fractured. The compressor, turbine, or propeller shaft would not rotate. The compressor blades were bent aft in the opposite direction of rotation with visual signs of dirt present. Internal components of the gear box rotated freely and appeared to be free of anomalies. The oil and fuel filters were absent of debris. The second stage turbine wheel disc exhibited radial/circumferential scraping against the third vane. Visual evidence of metal spray was observed on the trailing edges of the second stage turbine wheel blades. No anomalies were noted with the engine or airframe.
