the failure of a cylinder head exhaust rocker shaft boss while the aircraft was performing aerial application. Factors include soft terrain and a drop-off in the field where the emergency landing took place.

Read the full NTSB narrative

During an aerial application flight, the number six cylinder exhaust valve rocker boss cracked, and the engine would not produce enough power to keep the aircraft airborne. The pilot therefore made an emergency landing in a nearby lentil field. Although the touchdown was uneventful, during the landing roll, the aircraft went over a slight rise and became temporarily airborne. When it touched down again its propeller dug into the soft terrain, and the aircraft was thrown sideways, collapsing the main gear and bending the left wing.
