Probable cause

The pilot inadvertently descending into the ground. Contributing to the accident was the inflight opening of the hopper lid which partially obscured the pilot's vision.

Sequence of events

Analysis

The pilot of a crop duster inadvertently flew into the ground while returning to land after the lid to the hopper came open spraying the pilot with the chemical. The chemical partial obscured the visibility of the pilot and when he realized he was descending, the aircraft collided with the ground. The non-current pilot reported no mechanical problems with the aircraft.
