The NTSB's narrative final · quoted from the NTSB record

The aerial application airplane was observed in a steep left turn before it descended into a wooded area located along the edge of the field being sprayed. Eyewitness accounts indicated that the airplane was completing a course reversal after a spray run. The airplane exhibited substantial impact damage and fragmentation, consistent with a descent through a wooded area. The wreckage debris path was consistent with the airplane having a significant lateral velocity during the impact sequence. The investigation revealed no preimpact mechanical malfunctions or anomalies that would have prevented the normal operation of the airplane.
