Probable cause

Partial loss of engine power for undetermined reasons.

NTSB narrative

The pilot was departing on an agricultural application flight, and, during takeoff, the engine lost partial power. The pilot released the load of fertilizer and attempted to land on a road. However, the airplane was unable to sustain flight, and the pilot landed the airplane in a field. The airplane collided with concrete obstacles during the landing roll. Postaccident wreckage examination and component testing did not reveal a mechanical reason for the partial power loss. The reported weather conditions were not conducive to serious carburetor icing at cruise power; the engine was operating at a high power setting for takeoff, indicating that carburetor ice was likely not the reason for the partial loss of engine power.
