NTSB narrative
The pilot reported he had just completed an agricultural application pass and had entered a turn to setup for the next pass, when he heard a “pop” from the engine and felt the airplane slow down. His efforts to restore engine power were not successful. He dumped the application load and executed a forced landing to a road. After touching down, he maneuvered the airplane to avoid a tractor parked along the side of the road. Unfortunately, the left wing struck the sugar cane crop adjacent to the road causing damage to the lower wings, wing struts, and landing gear. A postaccident examination of the airframe and engine did not identify any preimpact anomalies consistent with an inability of the engine to produce rated power.
Probable cause
Total loss of engine power during the agricultural application flight for reasons that could not be determined.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
