## Analysis

THE AG ACFT WAS FLYING LOW OVER A WATER COVERED MUDDY RICE FIELD WHEN THE ENG STOPPED RUNNING. THE PLT THEN JETTISONED THE LOAD OF FERTILIZER & ENTERED A STEEP RIGHT TURN. SUBSEQUENTLY, THE AIRCRAFT STRUCK THE GROUND ON THE RIGHT WING & NOSE, THEN CARTWHEELED. A WITNESS STATED THAT HE THOUGHT THE PLT MAY HAVE BEEN ATTEMPTING TO TURN BACK SO AS TO LAND ON A DIRT ROAD. ONLY RESIDUAL FUEL WAS FOUND IN OR AROUND THE ACFT AFTER THE ACCIDENT. THE SURVIVING FLAGMAN/PAX STATED THAT HE WAS SURE THE ACFT HAD NOT BEEN REFUELED PRIOR TO THE FLT. THIS WAS THE LAST FLT OF THE DAY.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19860618031649A](https://openairdocs.org/incident/19860618031649A), Jun 18, 1986: Ayres S2RR1820, Dundee, MS, Destroyed. Engine failed inflight from fuel exhaustion. Pilot attempted a steep turn at low altitude. Aircraft struck ground.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
