Read the full NTSB narrative
The pilot reported that while engaged in aerial spraying, approximately 30 minutes after takeoff and 15 minutes after beginning to spray, he noted a reduction in engine power. He advanced the throttle, at which point the engine 'sputtered' and 'popped' a few times and then quit. The pilot performed a forced landing into a field. The airplane encountered soft terrain during the forced landing roll and flipped over. The pilot stated he did not use carburetor heat at the time. Post-accident examination of the engine did not reveal any abnormalities, and the operator successfully test-ran the engine following the accident. Temperatures of 7 to 9 degrees C and dewpoint of 6 degrees C were reported at two nearby weather reporting stations during the accident time frame. This temperature/dewpoint combination represents a hazard of 'serious [carburetor] icing at cruise power', according to FAA data.
