Narrative:
The aircraft was being used on an animal control flight, and the pilot was executing a low pass over a frozen, flat, snow covered lake surface, in pursuit of a coyote. During this maneuver, the gunner's weapon jammed, and the pilot diverted his attention to the direction of the weapon's muzzle, which was pointed toward a fuel tank. Immediately thereafter, the aircraft's wheels drug in the snow covered surface, and the aircraft nosed over. An overcast existed at the time, and there was a lack of references available on the smooth, even surface of the lake to enhance the pilot's depth perception.

Probable Cause: failure of the pilot to maintain altitude/clearance from the terrain (snow covered, frozen lake). Factors relating to the accident were: the pilot's attention being diverted to a perceived safety hazard, and lack of visual cues for pilot perception of clearance from the lake surface.
