What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Engine quit on swath run. No anomalies. Caraburetor icing conditions. Did not use caarburetor heat. Nosed over. (.4)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. (-23)during agricultural aerial application, engine failure occured. Pilot landing in field. Aircraft came to rest inverted. Fuel on board 1/2 full. Last power adjustment 15 minutes prior. Accident engine run indicated engine operating normally. Local weather observation (AWOS) indicated 1C temperature/dew point spread. Carb heat was not being used.
As the FAA filed it
ENGINE QUIT ON SWATH RUN. NO ANOMALIES. CARABURETOR ICING CONDITIONS. DID NOT USE CAARBURETOR HEAT. NOSED OVER. (.4)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. (-23)DURING AGRICULTURAL AERIAL APPLICATION, ENGINE FAILURE OCCURED. PILOT LANDING IN FIELD. AIRCRAFT CAME TO REST INVERTED. FUEL ON BOARD 1/2 FULL. LAST POWER ADJUSTMENT 15 MINUTES PRIOR. ACCIDENT ENGINE RUN INDICATED ENGINE OPERATING NORMALLY. LOCAL WEATHER OBSERVATION (AWOS) INDICATED 1C TEMPERATURE/DEW POINT SPREAD. CARB HEAT WAS NOT BEING USED.
