Narrative:
The engine lost power as the pilot pulled up from an aerial application run. The pilot immediately made a forced landing in a field and was unable to stop the aircraft before it collided with trees at the end of the field. Postcrash examination of the engine showed the right magneto distributor drive gear had several gear teeth missing, and the gear would occasionally not drive the distributor. This caused the magneto to lose timing with the engine. The pilot said he did not have time to cycle the magneto switches before making a forced landing.

Probable Cause: failure of the distributor drive gear in the right magneto, resulting in loss of engine power and a forced landing. The lack of suitable terrain for a forced landing was a related factor.
