Incident Description
The pilot reported that shortly after takeoff while en route to an aerial application operation, the engine began to lose power and started backfiring. In response, the pilot jettisoned a portion of the load to reduce weight and performed an emergency landing in a soft, unplanted bean field.
Emergency Landing and Outcome
During the landing roll, after traveling approximately 200 feet, the wheels sank into the soft soil, causing the aircraft to nose over. The aircraft came to rest in an inverted position.
Postflight Inspection
A postflight inspection of the engine revealed a crack in the No. 6 cylinder. The insurance company subsequently declared the aircraft a total loss.
