Analysis

The plt was practicing agricultural spray runs when the accident occurred. After making a steep right turn to align with the field, the acft descended and impacted the terrain.a post-crash fire ensued. Metallurgical exam of the rudder cable revealed that all wires on four of the seven cable strands were worn through. The plt was thought to have had less than 100 hours total flight experience. A teardown of the engine failed to reveal any anomalies which would have suggested a failure/malfunction.
