The NTSB's narrative final · quoted from the NTSB record
The 11,000-hour pilot reported that during an aerial application flight, the "engine began running rough." The pilot initiated a turn back toward the airport and "attempted to gain altitude." At an altitude of approximately 200 feet above ground level and approximately 1/2 mile from the runway when the engine "shuttered violently and quit." The pilot initiated a forced landing to a nearby pasture. The pilot stated that during the landing roll, the airplane impacted a wire fence, crossed two ditches, one road, impacted a second fence, crossed another pasture, and impacted a third fence before coming to rest upright in a plowed field. Examination of the radial engine revealed a piston connecting rod was separated the piston. The operator reported that at the time of the accident, the engine had accumulated 462 hours since major overhaul and 300 hours since the last annual inspection.
