NTSB narrative
The pilot reported that during an aerial application flight with an adequate supply of fuel onboard, the engine lost power. The pilot maneuvered the airplane for an off-airport landing and, during the descent, the airplane collided with trees then the ground. Postaccident examination of the engine revealed uncontaminated fuel and no discrepancies that would have precluded normal engine operation. The engine was removed from the airframe and sent to the manufacturer’s facility for an attempted engine run. Impact-damaged components were replaced, and the engine was placed in a test cell with a test club propeller installed. The engine was started; however, impact damage to the crankshaft precluded a full operational run of the engine. The engine had accrued 1.6 hours of operation since being rebuilt by the manufacturer. The reason for the loss of engine power could not be determined.
Probable cause
A partial loss of engine power for reasons that could not be determined because postaccident examination of the engine did not reveal any anomalies that would have precluded normal operation.

- 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. 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.
